ABSTRACT:
A collision alarm system for an automotive vehicle is provided which includes an object identifying circuit, a stationary object alarm circuit, a moving object alarm circuit, and an alarm inhibiting circuit. The object identifying circuit determines whether an object falling within a given detection zone is a stationary object or a moving object. The stationary object alarm circuit issues an alarm when a distance between the object identified as a stationary object and a system vehicle equipped with this system falls within a given stationary object warning distance. The moving object alarm circuit issues an alarm when a distance between the object identified as a moving object and the system vehicle falls within a given moving object warning distance. The alarm inhibiting circuit inhibits an operation of the moving object alarm circuit for a preselected period of time after the object falling within the given detection zone which has been identified as the stationary object, is identified as the moving object.
