Abstract
A collision-determining device arranged to prevent a passenger protection mechanism from erroneously operating by determining the polar relationship between an acceleration signal indicative of vehicle acceleration and a pseudo signal used to determine whether a vehicle collision has occurred. A G sensor generates the pseudo signal having a polarity opposite from that of a deceleration signal based on a control signal from a microcomputer. An A-D converter receives the pseudo signal via a signal processing circuit and generates a pseudo voltage. The microcomputer determines whether a collision has occurred based on whether the pseudo voltage has been generated and based on the polarity thereof.
