VEHICLE CONDITION DETECTING UNIT AND OCCUPANT PROTECTION APPARATUS INCLUDING THE UNIT

摘要

Vehicle condition detecting unit (1) comprising a sensor section (acceleration sensor (11)) for detecting of the behavior of vehicle; an integration processing section (integration circuit (12)) capable of integrating the physical quantity based on an output from the sensor section and generating an output signal indicating the condition of the vehicle; and diagnosing section (2) capable of feeding a self-driving signal to the sensor section and comparing the output signal obtained from the integration processing section with upper and lower limit tolerances preset for the output signal to thereby attain self-diagnosis of the sensor section.
