Abstract
A control apparatus of an occupant protection device has at least one front acceleration sensor provided in a front part of a vehicle, in addition to a room acceleration sensor provided in a room of the vehicle. Whether the vehicle is in a collision requiring a drive of the occupant protection device is decided based on each of sensor outputs of the room and front acceleration sensors, respectively, and the occupant protection device is driven when the collision is detected based on at least one of the sensor outputs. Since the front acceleration sensor is provided in the front part of the vehicle, the front acceleration sensor detects a collision acceleration early and gives it to the control unit, even in case of a collision, such as the offset or an oblique collision, in which a collision acceleration transmitted to the room acceleration sensor may be weakened. Therefore, the control unit can exactly drive the occupant protection device without causing delay in collision detection.
