ABSTRACT:
A control system for controlling the vehicle safety devices comprises first means for calculating from an acceleration signal produced by an acceleration sensor a first evaluation value related to vehicle speed change, second means for calculating from the acceleration signal a second evaluation value related to passenger position change, third means for squaring the acceleration signal and calculating from the squared value a third evaluation value related to the collision energy magnitude, operation control means for starting and stopping the calculations in the first to third means in response to the acceleration signal, and decision means for deciding whether or not to activate the vehicle safety devices in response to the first to third evaluation values. The control system can quickly and accurately discriminate and respond to collisions irrespective of type.
