Device and procedure with multiple accident estimation, algorithm for triggering a restraint in a vehicle with occupants.

摘要

Apparatus and method are presented for actuating a passenger restraint system in a passenger vehicle. A sensor senses vehicle deceleration and provides a deceleration signal having a value which varies in accordance therewith. A plurality of crash evaluation circuits each respond to the deceleration signal for evaluating the deceleration signal in accordance with respectively different crash evaluation algorithms. Each evaluation circuit provides a vote signal when its evaluation of the deceleration signal indicates that the restraint system should be actuated. The vote signals are summed to provide a summation signal. The summation signal has a fractional value dependent upon the ratio of the number of vote signals to the total number of evaluation votes. The restraint system is actuated when the summation signal exceeds a threshold level.
