Fahrzeugzustands-Erfassungsvorrichtung und Insassenschutzapparat mit derselben Vorrichtung

摘要

A vehicle state detecting device 1 includes a sensor section (acceleration sensor 11) for detecting the behavior of a vehicle; an integration processing section (integrating circuit 12) for generating an output signal indicating a state of the vehicle by integrating physical quantity based on the sensor output; and a diagnostic section 2 for supplying the sensor section with a self-driving signal, and for carrying out self-diagnosis of the sensor section by comparing the output signal from the integration processing section with upper and lower permissible limits preset for the output signal.
