    Hello Members,

    Recently I got interested in the process of how tesla makes its cars and even went to the extent of watching a documentary on YouTube about the creation of the Model S. What I didn't find was the process of installing the hardware and software simulation of the AutoPilot feature (probably because it was not available at the time).
    So my questions are..
    - How does tesla install this feature?
    - Is there a video that explains it?
    - Does tesla test out autopilot or not?
    - Do they actually drive every car on the road just to see if it actually works?
    - Or is it just predetermined that the technology works?

    Thanks,
    Jaspal Singh

    Hey Jas,

    Tesla installs the software at the factory and tests each car on their track outside the factory. Once the car is sent to the service center for delivery it goes through a final inspection and software update.

    If you're referring to the software update nature of Autopilot in the sense that you didn't buy it when you bought the car is can be activated by Tesla remotely as they can connect to the cars over the air. All the cars are connected to Tesla HQ through a VPN connection. They can also activate it at a service centre. My understanding is that if you decide one day that you want Autopilot you can simply call Tesla, pay them and they can activate it right there and then, no need to visit a service centre. Same thing applies to unlocking a battery too.

    Tesla does Autopilot development in-house and tests on the roads, at Alameda naval base and with a select group of beta testers (including ELon himself). Once the features are deemed safe enough they then do a limited rollout to more people then more widespread roll outs to the rest of the world, pending regulations of course.

    I have seen the "How it's made Tesla Model S" and it is very interesting. But, they do not show how the battery is made. I have a good understanding how with help from TrevP but it would be nice to see a video of it.

    Its classified, they said that in the documentary. The orientation of the cells is Tesla's "Formula."

    I'll try and find a clip that I've seen but it's really short. It's of a Tesla robot doing a pick and place of the cells into modules. Doesn't show much so nothing really lost. There's lots of pictures of the battery disassembled on the internet you can find with a simple Google image search.

    Folks,

    I have a question for you on the Tesla radar. (which is part of the Autopilot system).

    1. Is the Tesla radar a simple radar ? By that I mean does it just send out a pulse and then wait for a reflection to return. Then from the delay figure out how far away the object is. It does not know where the object is (left, right, up, down) just the distance and maybe the size of the object from the reflection strength.

    2. Or does the Tesla radar have some spatial resolution. i.e does it have any information on the location of an object ?
    One type of radar that can do this is a "Phased array radar" and some work has been done on this for automotive applications. (see link below).

    http://www.automotive-eetimes.com/n...tial-phased-array-radar-automotive-deployment

    Any idea where Tesla is with regard to it's current radar tech or where it's going ?

    Thanks
    James

    Given Elon's recent tweets concerning the radar, it sounds like it has a good bit of directional capabilities.

    Also Tesla uses both radar for distance and sonar for within 16ft on all sides of the car. My understanding is the radar does place what it sees, but the sonar may not. (plus the optical camera adding to the radar's information)
    Radar (RAdio Detection And Range) detects hard objects locations, their direction of travel and relative speed beyond the distance of the headlights and can 'see' thru visual obstacles like rain, fog, snow or other soft objects (IE person/animal).
    Sonar (SOund Navigation And Range) detects everything within 16' of the car, including a small child, dog, beachball or dump truck.

    I'm not so sure the Tesla radar has much resolution. If it did surely it would have been able to detect a large
    truck pulling out in front of a model S. It may be tuned to look at the ground in front of the car, to tune out overhead signs etc. Hence the gap under the truck looked like a clear road ahead. I think a phased array radar would have performed better in this case.

    Regards
    James

    The radar hardware is made by Bosch. You can look up the specs online.

    What they're doing in software however is really what matters. It's interesting to note that while Google and the other players are insisting on Lidar, Elon has said he doesn't think Tesla will need it. His recent tweet suggests they might have a lidar type of solution by using the existing radar hardware to create a point cloud.

    Here's some data on a Bosch radar unit.
    http://www.bosch-mobility-solutions...l_CO_PC_Driver-Assistance_641.html?compId=146

    So this is what I think is going on. The radar sends out a single pulse but the receiving antenna has an array of 6 antennas to measure phase and hence calculate position. I wonder if this is optimised for the horizontal or vertical ? Elon mentioned that overhead signs are an issue, so I'm thinking the antenna array is optimised for the horizontal . I suppose you could just turn the radar unit through 90 degrees.

    BTW....a true phased array radar has an array for both transmitting and receiving. Instead of just sending out a single pulse in all directions it can direct the beam and raster the environment to build up a picture.

    I think too much emphasis is being put on a single wreck where autopilot was engaged, but used outside of it's current limitations. If it interpreted the side of a trailer as a sign or not is irrelevant as the current system is designed to follow lane markers and vehicles traveling in the same direction.
    At it's current iteration, the system isn't broken or needing to be fixed. It is what it is and its crazy the blame is on the system. Tesla has said from the first announcement of AP that it would have multiple releases to build up to being fully autonomous, so why scrutinized it not acting like a fully autonomous system when they have clearly identified that it's not that (at this point)?

    It would be similar to expecting my auto-on/off headlights to control the high beams when oncoming cars are detected. Because it can do one thing doesn't mean it should do everything related that it wasn't designed to do. (my car is pretty low-tech and the auto on headlights is as 'autonomous' as it gets ;) )

    I am 100% sure, even before this wreck, the people much smarter than the majority of the public/media commenting on how it should have reacted, have been working on the next version that will go beyond the current version's limitations and have already considered how it should respond to cross traffic and on coming traffic conditions.

    (that little rant wasn't directed at you James, but more at every single person I've encountered in my day to day life that has commented on Tesla screwing up and their system having dangerous flaws since the FL story was released)

    There's no need to embed pictures of tweets in our system. Just copy the link to the tweet and our system will fetch and embed it for you!

    Yes, at the very least.

    Autopilot technology is still improving and will not wait for Model 3, it's going into Model S and X as soon as it's ready and whatever version is out when the Model 3 arrives is the minimum that will be implemented.

    I'm thinking more about the sensor hardware since the design is done.

    If they know in advance what they're going to do in terms of the AP 2.0 hardware then the wiring harness and general placement of the sensors are taken into account for the M3 design.

    OK - so are they building the wiring harness into the September Model S production line? How long does it take to go from drafting table to hardwired on the production line? Would that be "now"????

    I am anxious for my M3, so anxious that I probably going to execute a MS order soon. How soon? As soon as AP2 hardware is on the production line!! Tell me its SO!

    Autopilot price on the Model S is now $4,000 in Canada. Impact on Model 3?
