I think this is a pretty important point for any well-built self-driving software. Does anyone know if radar advancements could help increase this?
- MBCook 3y agoMy understanding is no. The big problem is that a stopped vehicle looks exactly the same to the radar as any other stationary object. So if it sees something stationary it could be a stopped vehicle or it could be a reflection from a road sign. Or a lip in the pavement. Or something else like that. Basically from what I’ve heard if it were to try and stop whenever it saw something stopped ahead it would constantly slam on the brakes unnecessarily. So stationary things have to be ignored, and it can’t save you from them. They all suffer from this. The only solution I’ve heard of is LIDAR but obviously that’s a huge step up.
