- drewg123 9y agoI'm pretty sure maps are important because having good maps and routing data is a prerequisite for better autopilot and eventually full self driving. I'm still hoping the $3K I paid for FSD will pay off...
- jijojv 9y agoThey use Google maps today already, so just another move to cut costs. They can make it pretty but data can't be better than Google's whose waymo.com has real FSD trials happening now.
- TaylorAlexander 9y agoWaymo appears to be ahead, but Tesla has little incentive at this moment to publicize anything partially complete. Waymo is certainly leading the pack on published capabilities, but Tesla has another advantage: tens of thousands of vehicles shipped with a sensor package they claim can support self driving. I’ve heard rumors they may need to upgrade the compute on those vehicles to support full autonomy, but no other company on Earth is better equipped to activate a fleet of tens of thousands of self driving cars (if the sensor package is indeed sufficient).
- astrodust 9y agoTechnically Tesla has far more vehicles on the road than Google does, and if they came up with a way to use their cars to capture data they'd have better maps than Google for major cities in the course of a single weekend. The problem is bandwidth for upload, but if SpaceX launches internet satellites the Tesla cars can get free access to...
- magnetic 9y agoI suspect they're doing that already. I don't think the bandwidth is an issue, unless they plan on reporting full frames of visual data (ie pixel maps) rather than vectorized or telemetry data. They can always use a store & forward approach if they want to limit their interface usage to WiFi. For real time data (like traffic conditions), even their 3G network should be sufficient (remember that they are already streaming music over it).
- drewg123 9y agoI don't think b/w is a problem. They are capturing different large chunks of video data already for improving self driving, and uploading via owner's wifi. Some owners with rooted cars have reported large video uploads, and have noted that Tesla seems to have a "trigger" system that uploads camera data based on certain conditions. Eg, "it was raining and driver reclaimed control from AP in a curve"..
- astrodust 9y agoI don't know about you, but I'd be pretty cheesed off if my car blew my bandwidth cap because it was secretly uploading terabytes of mapping information over the course of a month. If it was doing it via some other method, like via satellite, I wouldn't be concerned. Little car, do your thing!
- drewg123 9y agoThe kind of do and don't use Google maps. The center display shows Google maps, however the instrument cluster map and nav system uses an on-board traditional GPS system (like the tom-tom or garmin systems) due to them not being allowed to use Google for routing. The differences in the maps are sometimes jarring. Eg, the Nav will be telling you to turn onto "unnamed road" when the center console clearly displays the name.
- dogma1138 9y agoAutonomous vehicles need HD maps to be able to localize themselves accurately on a centimeter scale, GPS and current maps do not allow that. The higher the resolution of your map is the better and faster the localization is, better localization means better and more accurate decision making for your car. To illustrate it simply we’ve all been at a point where the GPS app we use put us on the curb or on a different lane sometimes even in incoming traffic. This is because your phone localized you erroneously. While we ignore it or make a joke about it if this happens to an autonomous vehicle someone can get hurt or worse. HD maps are the new gold rush in autonomous vehicles and companies are rushing to find ways to cheaply produce, update and more importantly distribute them to vehicles.
- jorvi 9y agoCurrent maps might not, but afaik Galileo has (will have?) centimeter accuracy by default and sub-centimeter accuracy when enhanced.
- dogma1138 9y agoThat isn’t a correct way of thinking about this problem and in more than one way. The first reason is that you want your car to be able to localize it self with its onboard sensors alone, this is always faster and more resilient than using GPS. GPS would put you in the ballpark and your localization goes from there. Second GPS and any other simmilar positioning system is only as good as your maps because they give you coordinates if your map isn’t accurate or the resolution of your map is lower than the resolution of your positioning system then you again lose localization accuracy. Galileo and GPS offer about the same resolution however high precision is costly (both in time and compute power) for both systems and you still need HD maps to be able to localize yourself on a centimeter scale.
- mycall 9y agoSnap to lane and quality learned vectors is good to compensate for bad GPS signals.
