Safety Concerns
- Real-life problems
- Sensors
- Failure modes
Automatic breaking AEB
Automatic emergency breaking AEB
- Detect objects
- Find range, velocity, heading
- Determine critical objects. Time to collision TTC.
- False positive: Nobody will buy a system with these
- False negative: kills innocent people
Stop the vehicle before colliding.
