ABSTRACT:
An accident alarm system continuously assesses the potential for a collision between a host vehicle and an object, based solely on input signals representative of the host vehicle velocity and the distance to the object measured at intervals at time t, by first assessing the status of the host vehicle to determine whether it is moving with constant velocity, stationary, accelerating, or decelerating, and then carrying out different signal processing routines to determine, as necessary, whether the object is moving with constant velocity, stationary, accelerating, or decelerating, the magnitude of the host vehicle and object accelerations, and the direction of movement of the object. Warning signals are generated based on these determinations, which assume that the vehicle and object will continue to possess the same acceleration or deceleration until a collision occurs. The system can also be used to activate additional safety devices by performing additional determinations as to whether a severe collision is imminent.
