Abstract This invention relates to an acceleration sensor system having self-checking the operation of an air bag safety system while a vehicle is being driven, an acceleration sensor element suitable for self-checking while driving is obtained by a planar piezoelectric element supported so that it can vibrate, a detecting electrode prodvided on an upper face of said planar piezoelectric element, and actuator means to add vibrations of a predetermined frequency to said planar piezoelectric element. A sensitivity checking circuit generates a sensitivity checking signal representing sensitivity of said acceleration sensod from said detected signal. A signal processing circuit generates an acceleration signal representing the applied acceleration to said acceleration sensor from said detected signal. An operation checking circuit generates a self-checking signal representing the operational state of the acceleration sensor system by checking the operation of said signal processing circuit and said acceleration sensor from said acceleration signal and said sensitivity checking signal.
