Abstract
A control apparatus of an occupant protection device, in addition to a room acceleration sensor provided in a room of a vehicle, has at least one front acceleration sensor provided in a front part of the vehicle. The front acceleration sensor, when detecting a predetermined collision acceleration, gives a detection signal to a control unit. The control unit sets a second threshold value lower than a first threshold value if the detection signal is input, and drives the occupant protection device when an integrated value of an acceleration signal of the room acceleration sensor exceeds the second threshold value. Since the front acceleration sensor is provided in the front part of the vehicle, even when a collision acceleration transmitted to the room acceleration sensor is weakened, the front acceleration sensor detects the collision acceleration early and gives the detection signal to the control unit. By this, since the second threshold value lower than the first threshold value is set, the control unit can exactly drive the occupant protection device, such as an airbag, without causing a delay.
