I was involved in a Nissan advertisement project connecting Playstation 4 with a cars as controllers[1]. They did a convention tour with 4 cars playing the same football game in front of a projector.

I did everything except front end and CAN interface though, $20 USB CAN reader device + python. I remember it took a while for my colleague to figure out the right input signals as the bus was quite chatty/high output, like tailing android logcat on verbose. We didn't use any factory unlock codes or anything to get more data.

As a gamer it was not really up to par - big deadzone when turning the wheel from one side to the other as we did not have time to get analogue movement read correctly.

On that particular car model you had to interact with the touch display every 15 minutes or else the whole car went into power saving mode and the CAN bus stopped sending messages.

Sounds like a really cool project to work on but the video is unintentionally hilarious

No, the game is not Rocket League, it's just a regular football game and all these players have to talk to the camera about how great it was to play FIFA with a Nissan Qashqai. All the absurdity of USB steering wheel memes, but played with a straight face

Wait, what? I guess that doesn't disturb ordinary operation, i.e. driving? Very easy of course to imagine a scenario when you drive and don't touch the display for 15 minutes.

That would have made sense if the CAN was for non-driving stuff only (like the entertainment system) but your application seems to indicate that not being true.

How does the car still operate if the CAN bus goes dark?

I'd assume that the demo car was not having its engine running - it's usual for cars to switch to power-save after 5-10 minutes, mostly to prevent cars from draining their battery if the user forgot to take the key out.

Presumably you can also have the engine running.
