ABSTRACT:
A method for functional testing of a lateral-acceleration sensor in a vehicle equipped with a dynamic stability control system. To simulate dynamic acceleration during driving on a curve, the sensor is checked by gravitational acceleration under static conditions. The method involves positioning the vehicle on a transverse ramp with known angle of inclination and comparing the acceleration force measured by the lateral-acceleration sensor with a preset sensor value determined on the basis of the angle of inclination of the ramp. The comparison is performed on the basis of amplitude and sign, and installation errors can be diagnosed based on an error log.
