Abstract
In a control system for actuating vehicle safety devices, data representing change in the detected vehicle speed is calculated on the basis of the acceleration sensed by a vehicle acceleration sensor. The data is compared with a reference signal depending upon the vehicle running speed to discriminate whether or not the change in the detected vehicle speed has reached a level determined by the reference signal, whereby the occurrence collision can be detected reliably and without erroneous detection over a wide range of vehicle running speeds.
