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. The front acceleration sensor detects an acceleration of the vehicle and gives the control unit a sensor output representative thereof. The control unit, when the sensor output of the front acceleration sensor is a sensor output caused by a collision of the vehicle, detects a variational quantity of the sensor output of the front acceleration sensor based on sensor outputs of the front acceleration sensor at two different time points, and increases an integrated value of an acceleration signal of the room acceleration sensor based on the variational quantity. Then, when the integrated value of the room acceleration sensor exceeds a threshold value, the occupant protection device is driven.
