An apparatus detects a collision according to a signal from an acceleration sensor 1, to deploy an air bag of a car. The apparatus prevents an erroneous deployment of the air bag when the car is driving along a rough road. The apparatus employs two deceleration thresholds for a signal from the acceleration sensor 1. The apparatus has a signal integrator 3 that integrates an area of the signal defined by the thresholds as well as an acceleration area of the same signal. The apparatus has a determination unit 4 that determines a collision if an integral provided by the signal integrator 3 is above a value corresponding to an OFF collision that requires no deployment of the air bag.
