ABSTRACT:
A method is disclosed for analyzing range and range rate data obtained by a vehicle obstacle detection system to determine whether the dynamic situation justifies alerting the vehicle operator of reducing the speed of the vehicle. Assumed values of vehicle and obstacle deceleration are used with known and assumed values of their velocities to calculate limiting warning distances that in turn are used to calculate an estimated warning distance. The estimated distance is compared with the range value as a basis of determining whether an alert is made.
