- Animats 7y agoThey did most of that back in 2015.[1] This is version 2. It's interesting what's happening as the control theory people get into machine learning. The controls people don't typically run a neural net as a controller. They use the trained net as a tool for building a controller with known continuity properties. The trouble with pure neural net controllers is that they sometimes do something totally bogus for some data point within the normal input space. That's not OK in control systems. This has all the math of machine learning plus the math of control theory and I don't understand it, although I sometimes look at the papers.

- AndrewKemendo 7y ago>They use the trained net as a tool for building a controller with known continuity properties. This sentence and comment is a revelation to me so thanks! I was very into control theory from 2001-2006 before jumping into Bayes nets and eventually ML. Having not really returned to CT since, it's always been a question in my mind how to use ML for SCADA & PLCs without running into the problems that you describe. As with most problems like this, it seems obvious now that it's described as such - though not actually obvious to those like me outside of it!
- sillysaurusx 7y agoI would highly recommend https://www.youtube.com/watch?v=PYylPRX6z4Q https://www.youtube.com/watch?v=PYylPRX6z4Q as a way of framing the problem. It seems like our options for ML are currently: self-play, dataset fitting, or human feedback. It's possible to solve any problem that can fit into one of those molds. (Unfortunately the opposite is true: if a problem doesn't fit into those categories, it seems very hard to solve with any form of ML.) But, now that I think about it a bit more, the sentence "use a trained net as a tool for building a controller with known continuity properties" seems neither obvious nor straightforward to do. I'm decently well-versed in AI techniques at this point, and I can't really think how I'd sit down and write a program that would generate such a system. Anyone have any leads? Basically, the goal is to make a neural net that helps you design a system that can be predictable. One way would be to write a loss function that penalizes unpredictability, and then let it run until it converges on a predictable control system. But that's a bit like saying "Just draw an owl." Not so easy to think of the actual code to do that.
- Animats 7y agoOne approach is that you have a semi-traditional control system, which has integrators, filters, adders, etc. All these components have tuning parameters, and tuning complex controllers is hard. But once you get them tuned, they behave in a reasonably predictable way. The machine learning part is used to get a predictor. You operate the thing and train a model of what will happen for various inputs. The machine learning system is just an observer in this training phase; it doesn't control anything. You train from recorded data. Then you use the trained model to tune the controller. The model lets you get an output for any set of inputs, so you can now choose input test sets which are suitable for tuning the model, like changing one input at a time and noting the output change. Automatically generating the structure of the controller (how those blocks are connected) is a separate problem. That's called "system identification". See [1].

- saagarjha 7y agoI was half expecting a Toyota Sprinter Trueno and Eurobeat. Pop references aside, though, what is this useful for? I thought cars were designed to not skid normally due to ABS?
- joshvm 7y agoI believe the idea is partially to understand how to train models to recover from skids. ABS gives you an assist, but it may be that the car can drift itself out of danger? > “We’re trying to develop automated vehicles that can handle emergency maneuvers or slippery surfaces like ice or snow,” Gerdes said. “We’d like to develop automated vehicles that can use all of the friction between the tire and the road to get the car out of harm’s way. We want the car to be able to avoid any accident that’s avoidable within the laws of physics.”
- sudhirj 7y agoABS is a very human-centric system the tries to keep the car controllable under low traction, often by sacrificing something aspect of movement. The neural nets here throw all that out of the window, and control the car with direct physics, without being once or twice removed from reality. The video also has some very interesting points about how the AI should be able to control the acceleration and braking on each wheel individually - so we really don't need to limit AI driving with human safety or control systems.
- tempestn 7y agoThat, and also ABS only prevents the wheels from locking (much) under braking. It doesn't help you if you enter a corner too fast, or hit a patch of ice, or stab the throttle too early on exit, etc. Traction control helps with the last of those scenarios, and modern stability control can start to help with others. But as you said, this system would theoretically be able to go straight to the most effective inputs in any given situation, since it doesn't have to deal with a human driver in the loop.
- taneq 7y agoThis was what finally killed my long-held attitude of "we don't need no stinkin' ABS". No matter how good I am, I will never be able to independently limit-brake each wheel of my car.
- spectramax 7y agoThis could be a pay-to-ride-for-thrill startup idea. What a ride!
- m0zg 7y agoUntil someone spills a bit of oil on the pavement and it drifts straight into a nearby wall because oily pavement is "out of domain" for its deep learning systems.
- djmips 7y agoIf you notice in the video there are no nearby hard walls, it's a giant open parking lot and the course is set up by soft pieces like plastic traffic cones. I'm sure a course could be made with appropriate margins for safety. Even so, in the ride world there are accidents but that doesn't stop people from riding.
- chongli 7y agoNot to mention the fact that this system is monitoring the traction of all 4 wheels constantly and would detect the slip in milliseconds, transferring power to other wheels. It would be fine. They probably already have a bunch of lubricant on that lot in order to reduce wear on the tires.
- metaphor 7y ago> They probably already have a bunch of lubricant on that lot in order to reduce wear on the tires. That's a real skid pad at a real road course[1] with real rules and regulations[2], not some expendable engineering testbed greased up to save tires.

- yobananaboy 7y agoOn top of that, there's the deadman's switch on the console that stops the car if the driver releases it. Would definitely pay to ride in something like this.
- jamestimmins 7y agoSo is the general idea that by removing the automated controls, which normally limit drift so human drivers don't lose control, they're able to gather data at the extremes of car handling? I'm curious how this would be applied in the real world. It almost seemed to suggest that a self-driving car would operate with those stability controls turned off, allowing it operate evasive maneuvers that would be impossible in a human-driven car.
- jcims 7y agoI think you have the right idea, this is just dipping the toes of autonomous vehicles into the pool of kinetic friction.
- zone411 7y agoStability control is just another algorithm running in the car so it's logical that a more general system would supersede it. Keeping existing code in place would limit car's possibilities and increase complexity.
- mmerlin 7y agoI'd like to see this car vs humans in the Hyperdrive series on Netflix
- dharmab 7y agoDrifting is objectively less effective and safe than normal manuevering and braking. Drifting as a sport exists to look cool and stylish. It's like figure skating with cars. (There is one exception- off road racing on loose surfaces requires drifting. But driving that way off road is only useful for speed at the expense of safety and reliability.)
- tempestn 7y agoAnother exception of a sort, and I believe the one this research is meant to address, is when the drift is initiated unintentionally. Say you hit a patch of black ice mid-corner, for example. This kind of work can expand the envelop of the control system to encompass these scenarios.

- joejerryronnie 7y agoYou’re telling me that not one Stanford engineering student could come up with a mock Flux Capacitor?!!
- hirundo 7y agoI guess if you can afford a DeLorean you can afford to keep replacing the tires you burn up by drifting on pavement. I'd rather have my car programmed for long tire life and high mpg please.
- campfireveteran 7y agoIn the US, a new DeLorean isn't all that expensive compared to typical "jelly-bean" vehicles that are the most common. Back in 2005, I narrowed down a vehicle purchase decision to a new DeLorean, an used Lotus Elise or a new G coupe. I went with a bone-stock manual G that I kept for a few years before I got into Cold War-era West German and French vehicles. I'm not a rich person, far from it.
- LoSboccacc 7y agothe worst part of the 2009 crisis is that the the European used car market is shot I got a 3 year old gt in 2007 and with that money today I could barely get a panda.
- chrisseaton 7y ago> a new DeLorean They're still making them?
- A_Parr 7y agoSort of. Someone bought the leftover parts from the original factory, and brought back the company name, selling completely refurbished ones. They've been trying to sell completely new ones as a low-volume automaker, but haven't successfully navigated the bureaucracy on that so far.

- keyle 7y agoThat's incredible footage just on its own :)
- ohadron 7y agoSomewhat reminds the progress airplanes did in the 1970s with fly-by-wire technology. Specifically they way it was utilised in the F-16. Moving from directly piloted controlled surfaces (rudder, elevator, flaps, ailerons etc) to using a computer to convert the pilot command input to servo actuators. Flight surfaces had much more authority, much better performance could be achieved, but the flight computer was in charge of safety and keeping the aircraft within limits. https://en.wikipedia.org/wiki/Fly-by-wire https://en.wikipedia.org/wiki/Fly-by-wire
- Neil44 7y agoSteer and brake by wire is a safety thing, all manufacturers so far have kept a mechanical link in place despite electric assistance because of the potential for lawsuits. Infinity has gone the closest to full steer by wire so far that I’m aware of.
- bborud 7y agoWell, a very key factor of steering is that it connects your fingers to the interface between tyres and road surface and imparts critical information about what’s going on there. If you decouple the steering completely from the mechanical bits you have to recreate that channel of information. Which isn’t necessarily easy to get right. Even servo assisted steering systems can easily become a bit numb. If you have ever driven a tractor it is very different from a light sports car without power steering for instance.
- xeromal 7y agoI drove an old redneck work truck once that someone installed assisted or power steering into. It also had a giant steering wheel from before that stuff was installed so it was comically easy to drive.
- Too 7y agoI’ve heard steer by wire can have faster feedback than pure mechanical systems. Even a mechanical steering has lag in cogs and there is never 100% stiffness in the steering column, etc.
- fouc 7y agoSeems like a DeLorean isn't necessarily that expensive, prices range from $20,000 to $45,000.
- Already__Taken 7y agoLooks like they had fun with it given the car didn't matter as they replaced the brakes, engine and suspension.
- psim1 7y agoAre you telling me they built an automated drift car... out of a DeLorean? The way I see it, if you’re going to build an automated drift car, why not do it with some style?
- dragosmocrii 7y agoArticle mentions each tire gets 7,000Nm torque from its electric motor. Is that a typo?
- jcims 7y agoProbably not. Teslas, for example, have a ~9:1 drive reduction from motor output shaft to drive wheels. 1000Nm is a high torque motor to be sure, but not that hard to find.

- grecy 7y agoI genuinely hope Tesla get a 2020 Roadster to lap the Nurburgring on autopiliot with nobody inside. If it lives up to promises, it will easily set the all time lap record as the fastest vehicle ever. It will be an interesting time when a $200k production car can whip the pants of a multi-million dollar F1 racecar.
- abcpassword 7y agoF1 could go faster. They’re limited by the regulations. Literally “formula” cars.
- kart23 7y agoTheres no way a tesla roadster is beating the current record holder, the 919 evo. The roadster would be magnitudes heavier, plus it wouldn't have the aero for the downforce. https://youtu.be/PQmSUHhP3ug https://youtu.be/PQmSUHhP3ug
- grecy 7y agoObviously we have to take it with a grain of salt, though Elon said it will. So far we've heard of an 8.8 sec quarter and 0-60mph in 1.9s. The chief designer also said it will better all publicly announced numbers.
- danielh 7y agoElon Musk claimed in a tweet that the roadster can beat a time of 6:44 min on the Nürburgring Nordschleife, which is (currently) 20.832 km long. The current lap record for street legal cars is 6:40 set by a Porsche GT2RS MR. The overall record is 5:19.55 set by a Porsche 919 Evo. F1 last raced the Nordschleife in the 70s. The lap record is 7:06.4, but the track was 22.835 km long back then. The Roadster might have a chance at beating the lap record for street-legal cars, but physic will make sure that it will not come even close to an overall lap record.
- grecy 7y agoDon't forget the 2020 roadster will actually have rocket boosters. (Elon has given his word on this more than once)
- GistNoesis 7y agoSo, in Back to the future : Tokyo drift, did MARTY met Sally when Flash tried to bring back Doc (Hudson)...
- lecarore 7y agoI'm impressed by how well this complicated page renders without javascript.
- fieldmeasure 7y agoDon't get me wrong I think this is an impressive feat and I am always impressed to see universities pull off these kinds of complex system and control projects. Yet, there are a few things that I would like to mention. The article says that the car does "doughnuts with inhuman precision" and they want to develop vehicles that can handle "emergency maneuvers or slippery surfaces like ice or snow". In this context, I feel this demo falls a bit short. The car can drive with superhuman precision, but it also gets superhuman capabilities like inch-precision localization (and an IMU is my guess) or superhuman steering wheel turning speeds. And the vehicle is heavily modified for this specific use-case. Drifting looks stable in the video but I really cannot judge how much easier it is with this car than a normal car. In addition, the asphalt also looks fresh and clean. I would like to see what happens if it suddenly encounters wet surfaces (or ice). edit: typos
- sudosysgen 7y agoInch precision localization isn't out of the grasp of human drivers. Kimi Raikkonen at Monaco coming millimetetd from the walls repeatedly comes to mind. It also isn't out of the abilities of a bog standard optical SLAM+IMU.
- matt-attack 7y agoDon’t forget a “normal” car is typically front wheel drive. I’m fairly certain drifting like this is nearly impossible with front wheel drive.
- Jamwinner 7y agoCorrect in this case. And to a pro driver, this is not drifting. This is donuts. Mashing the gass to lose grip is the lowest tier of 'drifting'. Real drifting as racers do it uses mostly the momentum and changing inerta from braking at corner entry to get sideways, using the gas only to modulye traction. That can be done in any car, fwd included.
- taneq 7y ago"This leads to the physically insightful result that one can use the rotation rate of the vehicle's velocity vector to track the path, while simultaneously using the yaw acceleration to stabilize sideslip." This sounds like what every racer will tell you: When the car is sliding, you control your direction with the throttle and control the angle of the slide with the steering.
- mootzville 7y agoI want a longer version of the drifting with some classical music as a backdrop
- williesleg 7y agoI'd say that would be fun to put gramma in and send her to the grocery store!
- deleted 7y ago[deleted]
- devit 7y agoDoesn't this sort of movement cause a lot of wear on the tires, thus making it unsuitable for routine use?
- Digit-Al 7y agoIt's not supposed to be for routine use. The idea is that if the car gets into a situation where stability is lost it will know how to handle it. As an example, imagine an autonomous car is going around a bend and hits a large patch of black ice and goes into a slide. Current systems will struggle to handle the car and it could result in a crash. With this knowledge added the car will know how to handle slides and will recover easily. Another example (given in the article) is if a person darts out into the path of the car it can perform a sharp turn and gracefully handle manoeuvring around them without losing control using this knowledge.
- HeWhoLurksLate 7y agoThis is exactly right. Recently, I drove a big 4WD SUV at about 5 mph onto ice in the middle of a 90 degree turn and lost traction in the front, and instead of doing anything helpful, the system decided the thing to do was engage the parking brake, which instead of stopping the vehicle put it into a slide, and almost got damaged because of it- when the vehicle stopped, it was less than half an inch away from a big transformer box in the front and less than 5 inches away from a concrete pole on the passenger's side. I think I honestly could have done better without traction control than the stupid stutter-stutter click slide that came with it in that situation.
- toss1 7y agoYes, but. Yes #1 is that this is mostly Drifting techniques, which are mostly for show/style competition. The tyre slip angles mentioned are around 40deg, far past the optimal level of grip. Yes #2 Racing techniques are more explicitly seeking to optimize for maximum grip, often found around 3 to 6 degree slip angles (depending on tyres, tyre pressure, tread & road temps, road cleanliness, dryness, etc.). Both still are in the ranges of tyre slippage, at the edges of control, and burn tyres at crazy rates vs street use (drifting just insanely so). Moreover, as someone with race training & experience, I can say that anyone doing full race/drift techniques on the streets as an ordinary practice is a real a*hole & a hazard. BUT, all that said, it is absolutely critical to have thise techniques in your bag of tricks, available to use when something exceptional happens. In those rare-ish events, being able to use the full performance envelope of the vehicle is a real life saver, both for you and the others nearby. So, for sure not every day, but these guys are absolutely right about the need to work on the full dynamic range of the performance spectrum.
- fourthark 7y agoIt sounded like it precomputed the route, steering, drift for the whole course first, then executed it. If the friction were variable and unknown it would get completely lost.
- ehnto 7y agoWhich is very common, even in controlled drift events. Over the course of a single run, tires can completely change grip coefficients.
- fourthark 7y agoSo you got the sense that it was recalculating based on the response it got? I wasn’t clear on that from the article.
- ehnto 7y agoI combed through the article and a previous article linked in it, but I can't find any concrete answer one way or the other. My intuition is that it would have to be recalculating it's inputs as the environmental variables change. They could have modeled in expected tire friction coefficient changes, or perhaps the task is more forgiving of that changing variable than I expected. One of their stated goals is to drift in tandem with another human driven vehicle though, so they are likely aiming for complete, adaptable autonomy.
- asdfman123 7y agoCan we just stop for a minute and admire the fact that there are people out there who have found a way to get paid to program a DeLorean to drift?
- lyjackal 7y agoMy thoughts exactly
- YeGoblynQueenne 7y agoMore like, if you can program a DeLorean to drift, someone will pay you for it.
- tachyonbeam 7y agoThat's definitely not true. Making something cool and useful doesn't necessarily translate into making money. In this case, these people are getting funding because they convinced someone that this was useful research, probably through a grant application of some kind.
- jayeshsalvi 7y agoNext step: Controlled flip!
- deepsun 7y agoImagine if the car could also do that in the air, where the "ground" is unstable and changes all the time, but autonomy system should still maintain narrow range glissade. Wait, that's called landing autopilot.
- mensetmanusman 7y agoThis group has done good work, and at talks about their work I was able to come away with an interesting trivia. When they try to compete with the best racers in the world, they do lose by a consistent amount. It turns out the human racers are constantly pushing the vehicle+tires to the limit of control to understand the sharpest possible turns they can make without losing time. As the tires wear, the human is in constant learning mode to compensate turn approaches as the coefficient of friction changes. Work on the DeLorean will hopefully feed into their racing controls and then they might be able to beat the best human racers in the world on arbitrary tracks.
- Fjolsvith 7y agoI see James Bond plot twists in the future.
- cdnsteve 7y agoKen Block eat your heart out. He should trademark an enable Block mode.
- chkaloon 7y agoBack in the late 70s, my high school driving instructor said "don't tell your parents, but the best way to learn how to control a car is to go out to the school parking lot on a snowy night and spin donuts." Funny that they are finding that artificial intelligence can use the same method.
- xeromal 7y agoHe's not wrong. When there's a solid snow, I love to find an empty parking lot and just do some stupid maneuvers. It really let's you get a feel for what works and what does. Like, if I turn my steering all the way and slam on the brakes. How far do I slide. Where do I end up? It's really good for getting comfortable with all kinds of scenarios
- perl4ever 7y agoI've never tried it with a RWD car, but as a teenager, I thought the behavior of FWD in the snow was really fun. Go around a turn as fast as possible, and push on the gas pedal, it slides towards the outside, front first. Let off on the gas, and the front snaps back to the inside of the turn. I also buried my car in a snowbank more than once and had to dig it out.
- chkaloon 7y agoI always thought RWD was more intuitive, and in this video the car appears to be RWD. It probably depends on what you grew up with.
- zzzeek 7y agothey have gotten this car to do complex and exotic movements via automated manipulations of the car's human-oriented interface, that is, a single steering wheel, four wheels that turn in the same direction, and then the brakes / accelerator. It seems though that if you are actually trying to design autonomous cars that feature greater maneuverability than what is normally possible you'd instead ditch the whole assumption of a single steering column and all of that and just consider all the wheels as independent, or maybe add more wheels that engage for some kinds of maneuvers, or probably a whole lot of other things that im sure all the car people here know are possible if you are no longer constrained to controls created for a single human with only four limbs and extremely limited coordination and reaction time.
- DreamScatter 7y agoThe people working on this car are designing a vehicle control system, not an actual new vehicle.
- freedomben 7y ago> Besides, MARTY, the driver :-D Too many software engineers overlook the fantastic opportunity for cleverness when naming things. It's one of the hardest problems in computer science, but one of the most rewarding.
- sap9433 7y agoIf self-driving tech has become so advanced, I wonder why Waymo is not delivering anything? I wonder why is Tesla taking forever to deliver self-driving, why Uber discontinued its self-driving program, Why Apple ain't serious about Apple car yet? Does this demo hide something that we should know?
- papreclip 7y agoA couple traffic cones out in the street could direct this thing onto the sidewalk, where it would drift over pedestrians or slam into a brick wall without hesitation. There's a big gap between a car that can drive on a closed course and one that can navigate the real world for millions of miles without killing anyone
- btbuildem 7y agoI think in this demo they simply paint a path for the car to follow. The cones etc are there just to help us see whether it's following the path well. If there was a cone in the middle of the path, it would've run right over it.
- thr0w__4w4y 7y agoYes, this. Not trying to take anything away from this, but this car is essentially "running a program." I would love for someone to come on here from the program and publicly repudiate what I'm about to say. I bet they ran that "dance" hundreds of times, no cones or hay or obstacles, got it to the point where it was precise and repeatable enough to then set up the cones and barriers (I mean, we have robots that place parts to within 0.001" or better repeatably). What would impress me (seriously). I go out the L.A. Colliseum parking lot, set up cones / a track that the car can definitely do (based on radiuses & turns in this video), the car "studies" the track (I don't care if a drone looks at it & takes measurements), and then the car calculates and executes a perfect path through the course the first time without hitting anything. Again, not trying to crap on this, I'm just saying that anyone who's worked in controls, automation, engine control, etc. (I've done all these & more) isn't utterly wow'ed by this. Kudos, but we didn't just put a man on Mars.

- natch 7y ago“It almost like as if we did some math for this.” lol, awesome.
- tzs 7y agoI wonder if it would be feasible to make a fleet of race cars that have self driving technology that has each car communicating with the others and monitoring the human drivers, with the car letting the human drive but able to step in if the human tries to do something that would cause a crash? I bet you could make some pretty good money with such a fleet running open races that members of the public can pay to drive in. The self driving system could keep track of the number and severity of its safety interventions which could be used to give time penalties at the end of the race [1], so that the winner is determined by the skills of the humans. Besides racing, you could also do car chases that recreate scenarios from action movies. Add in something to simulate guns, and you could do scenarios where a car with a driver and a couple armed passengers is trying to escape a couple pursuing cars, each with a driver and armed passenger. [1] Or maybe actually do the time penalties during the race. If the self driving system has to take over from you, it could slow you down for a bit before returning control to you.
- DreamScatter 7y agoI doubt race car drivers (who are better drivers than the average car driver) would want a computer to yank their steering or do something unexpected in a race. Autonomous cars aren't necessarily better than race car drivers.. would be interesting if human racers and autonomous compete
- Jamwinner 7y agoThere has been progress since the millenium on race traction control. In the beginning, it was a crut h for bad drivers. Some systems today are banned in racing. Both for ocassional advantange, and for not-occasional mishaps that endanger other drivers. It always seemed odd to me that tech not safe enough for racing is now mandated on the road.
- EGreg 7y agoCan an autonomous car beat the best version of Frank Martin in The Transporter series, let alone any of the Fast & Furious drivers? Now we have the answer. It’s game over people! Even the fictional drivers in the movies have no chance against real world AI today. This means in the future when an autonomous car or robot is chasing you — you may as well give up. You just better hope it doesn’t get cheap enough that someone can simply hire a swarm of robots or autonomous cars to kidnap people or incapacitate them or wreak havoc en masse (eg crashing into 10,000 gas stations at once).
- fnord77 7y agoI seem to recall a video Thrun's/Stanford's DARPA car "Junior" drifting in a parking lot autonomously. Around 2007. Cannot find the video, though.
- slowhand09 7y agoResponse is twofold: I think the cars maneuvering is impressive. How did they get enough power from a a DeLorean to drift? Hail to MrFusion!
- Jamwinner 7y agoExactly, that terrible french engine makes a delorean a terrible car to actually drive. It is likely one of the many with an engine swap. As cool as they look, buy are they crappy cars. The lotus designed suspension cant help being overweight, underpowered, and assembled in northern ireland during rough years. I wonder if the tesla truck will fare better.
- Jamwinner 7y agoFunny, I built a mechanical rig to do figure 8s years ago. It was some rope and a few pulleys, and caster adjustment on the car. This seems like using a laser to peel an apple for internet points.
- nkrisc 7y ago> This seems like using a laser to peel an apple for internet points. How so? From what I can tell they're working to improve autonomous vehicle handling in extreme situations. That seems very practical and useful. I'm curious how you arrived at that conclusion about "internet points." Because the question I really want to ask you is against the rules here. Also the capabilities of your mechanical rig pale in comparison to what this can apparently do.
- Luechkt 7y agoWhere we're going, we don't need roads.
