ABSTRACT:
A collision detection system utilizing a set of primary sensors and a secondary sensor. When a sufficient collision load is applied to the sensors, the sensors output a signal. The primary sensors are constructed to be more sensitive than the secondary sensor. Based on the outputs of the primary and secondary sensors, a control unit detects the collision. Upon detecting the collision, the control unit outputs a collision detection signal which activates a protection device, such as an air bag.
