They have a Bosch supplied radar but insisted on doing their own signal/object processing.
- Animats 9y agoWhat seems to have gone wrong in radar processing is that they'd get false alarms when approaching an overhead object such as an overpass when not on flat ground. Older model automotive radars scan horizontally, but not vertically, so there's no height information. The "solution" was to ignore some of the radar returns, not fit a better radar. Even with that, there's no way that the China incident of rear-ending a street sweeping machine on a freeway should have happened. From the crash videos, it looks like any obstacle not directly ahead of the vehicle centerline is ignored. 2D scan radars exist.[1][2] Tesla didn't use them.
