Corrective device for acceleration sensors, has control unit with processing unit to input self-diagnosis check signal to sensor and to execute offset corrective operation of sensor output before check signal is entered

摘要

The device has a control unit (3) for processing an output of an acceleration sensor (1) to make a collision judgment and for executing an activation processing of an air bag (7). The control unit includes an operation-processing unit (3) for inputting a self-diagnosis check signal to the acceleration sensor and for executing an offset corrective operation of the output of the sensor before the check signal is entered. AN Independent claim is also included for a method of correcting an output of an acceleration sensor.
