@atpfm@siracusa@caseyliss@marcoarment I’m quite confident speedometer and cameras (in addition to drivetrain function) is on a RTOS. You can reboot a Rivian infotainment and it’ll show a crappy speedometer number and camera feeds on a black screen the second you reboot it even as the infotainment is rebooting (this also works under a full car reboot too FWIW after about 2-3 seconds after initial “on.”)
@siracusa@snazzyq I’m behind on ATP, and I’ll listen when I get a chance, but it’d be bananas to the point of being dangerous if it wasn’t an RTOS. There are commercial OSs available that can be customized to do what they’d need. I’ve a high regard for Rivian and I’d be shocked if they’d half assed something that important.
@snazzyq@siracusa true, but when you consider how the camera feeds and speed information feed into various safety features (adaptive cruise control, auto emergency braking etc) it makes sense these would be managed by a RTOS. This page from QNX (RTOS used by Rivian) specifically uses adaptive cruise control as an example where a RTOS is needed. https://blackberry.qnx.com/en/ultimate-guides/software-defined-vehicle/automotive-rtos It’s hard to find documentation, but I imagine the RTOS handles the data and the infotainment OS makes it look pretty.
