METHOD AND APPARATUS FOR DIAGNOSING INERTIA SENSOR

摘要

A control system adapted to be mounted on a motor vehicle for control of a motor vehicle system in accordance with the inertial state of the motor vehicle. The control system includes an inertial sensor providing an inertial measurement output in accordance with the inertial state of the motor vehicle, where the inertial measurement output is referenced to a reference voltage. A controller is provided for controlling the motor vehicle system at least partially in accordance with the inertial measurement output. The controller includes a circuit for comparing the reference voltage used by the inertial sensor to a nominal voltage. The circuit causes the controller to discontinue use of the inertial measurement output when the reference voltage deviates from the nominal voltage.
