Under the hood of the Subaru Levorg: ADAS and programmable logic
- BoorishBears 6y ago> Everybody realizes that the more sensors you put on cars, the richer the fusion of data you get. Well, not everyone... I hear we're getting a cross-country drive in 2019 using just cameras
- cma 6y agoHow about that robo taxi network that operates without anyone in the driver seat in all human-drivable conditions and all human-drivable locations that is supposed to release in the next 4 days. They said they just needed winter 2019 to make sure it was trained up for ice and snow.
- gumby 6y agoPatience, please! Just wait until 2017 by when, it has been predicted, we will a ton of self-driving cars on the road.

- flyinglizard 6y agoQuite impressive of Subaru - a tiny manufacturer by automative standards - to go their own way instead of buying from Mobileye etc.
- netsharc 6y agoHmm, the article says they're buying from Xilinx... Never heard of this company before, but opening their website the headline is that AMD announced a while ago they were acquiring them...
- flyinglizard 6y agoXilinx provides the logic chips, but building the system around that seems totally up to Subaru.
- sgerenser 6y agoYes, buying chips from Xilinx would be a bit like buying CPUs from Intel, not like buying a complete turnkey solution from MobilEye (which I realize is also Intel).
- uxp100 6y agoYeah, I wasn't quite sure of that reading the article. I think to prove the usefulness of this hybrid SoC they did at least some of the development. There are situations where Xilinx makes a commodity product that you buy from a distributor, but based on almost nothing, I really suspect developing the software and logic of this system was a subaru/xilinx partnership, or maybe primarily Xilinx.
- touisteur 6y agoMaybe middle of the road. Xilinx seem to have developed a lot of CNN/DL API/library stuff recently. Far from turnkey, but I wasn't expecting so much stuff when I looked it up recently.
- cf100clunk 6y agoSubaru is the automotive manufacturing component of a conglomerate once known as Fuji Heavy Industries but now called Subaru Corporation. I'm not surprised at the home grown tech being available to create this in-shop product. As you say though, impressive.
- d136o 6y agoI got a 2020 forester at the start of the year and did three round trips to LA and Bay Area which allowed me to learn how well the eyesight system works right now. I took Interstate 5 along the San Joaquin, pretty much a straight drive (I wouldn’t call it boring because the farmland is pretty beautiful). It works very very well in predictable highway situations. Basically something I felt safe and comfortable using while in the leftmost lane, where there were no exits. It helped maintain the set speed subject to the constraint of maintaining a distance to the next vehicle. It also did lane keeping pretty well. But it’s not a perfect system and it’s important not to trust your life to it: * once, when on the right lane of two lane I5, it veered towards an exit ramp while going 60 mph+. I had looked away to grab a French fry. * the detection of the car ahead of it isn’t perfect, I’ve had cars merge into my lane, which weren’t detected immediately, and distance wasn’t added until the system self corrected eventually. * false positives on obstacle detection. It’s happened a few times, where hard sun lighting on the highway, combined with shadows on the payment from bridges/trees/other seem to make it pick up an obstacle and make the vehicle start to break hard. * I get the sense that the control system doesn’t account for the physics of the car. For example, it’ll take highway turns at high speeds, because that’s the set speed. But we humans know to slow down as we enter such turns. They need to add a bit of fear of the unknown to this thing hah. All in all it’s a neat system that makes highway driving fun. But one needs to closely monitor it or it’ll lead to a new class of accidents. For city driving the only time I might consider using it is for bumper to bumper really slow traffic. Again with close supervision. But there hasn’t been much city driving during pandemic.
- chiph 6y agoA coworker in Austin had a Subaru with the EyeSight system, and it would hard-brake on RM-2222 when it saw the rock walls in a curve. Presumably the "obstacle" took precedence over the fact that the road was curving. She pretty much had to stop using the system on her commute. https://goo.gl/maps/BdzW5Y1aQdFNKKSt6 https://goo.gl/maps/BdzW5Y1aQdFNKKSt6 GM's Super Cruise system looks impressive (caveat: I haven't tried it out yet). But I'm not sure they have the funds and corporate will to create the LIDAR maps of the US road system that are needed for full coverage. https://www.cadillac.com/ownership/vehicle-technology/super-cruise https://www.cadillac.com/ownership/vehicle-technology/super-...
- syntaxing 6y agoDoes anyone know of any car manufacturer that offers a SUV that has the ADAS capabilities similar to OpenPilot that’s not Tesla?
- bitexploder 6y agoJust curious why exclude Tesla? Their lane keeping and autopilot is better than anyone else’s I think.
- lhoff 6y agoProbably because he already knew that Tesla hat something like that. But since Tesla is (sadly) still and outlier as the don't produce gas engine cars it might not be seen as a company in the same field.
- syntaxing 6y agoMainly distance, I need something that can go further than 300 miles a day easily
- seppel 6y agoUnless you mean something specific, at least Mercedes, BMW, Audi and Volvo offer very good ACC with lane assist in their SUVs.
- the_pwner224 6y agoNissan and Honda's implementations are also pretty good.
- johnrgrace 6y agoIf its has to be a SUV, GM has Supercruise coming out on the 2021 Escalade.
- bch 6y agoADAS == Advanced Driver Assistance System, which I didn’t know. Annoyingly “ADAS” is used in the article without description, until the text of a figure.
- Treblemaker 6y agoLikewise ASIL - Automotive Safety Integrity Level https://en.wikipedia.org/wiki/Automotive_Safety_Integrity_Level https://en.wikipedia.org/wiki/Automotive_Safety_Integrity_Le...
- PopePompus 6y agoOh, God help us - it apparently honks the car horn automatically in some situations. Fully autonomous driving may or may not be "AI Complete", but deciding when it is appropriate to honk the horn definitely is.
- souprock 6y agoThe feature should be called "road rage assist". After honking the horn, it could bring the car to a stop. Then you get out and brawl. (it's not a full self-fighting car yet)
