Method for determining the yaw rate of a vehicle

摘要

The laser (12) on the road vehicle (10) can scan a semicircular area (14) in front of the vehicle. It can send out short pulses of light which may be reflected off other vehicles (16,18). Reflections may be received from various parts (34,36) of the nearby vehicles. Signals received at different times may be compared to calculate relative speeds of other vehicles.
