Abstract:
A control apparatus of an occupant protection device having a room acceleration sensor, provided in a room of a vehicle, for detecting an acceleration of the vehicle and outputting an acceleration signal representative thereof, comprising:at least one front acceleration sensor, provided in a front part of the vehicle, for detecting the acceleration of the vehicle and outputting an acceleration signal representative thereof or an integrated value of the acceleration signal as a sensor output; anda control unit, connected to said room acceleration sensor and said front acceleration sensor, for inputting the acceleration signal of said room acceleration sensor and the sensor output of said front acceleration sensor,said control unit driving the occupant protection device when an integrated value of the acceleration signal of said room acceleration sensor exceeds a predetermined threshold value,said control unit detecting whether the vehicle is in a collision requiring to drive the occupant protection device based on the sensor output of said front acceleration sensor, and increasing the integrated value of said room acceleration sensor when the collision is detected based on the sensor output of said front acceleration sensor.
