Diagnostic method for use with a vehicle dynamic control system (vdcs)

摘要: A diagnostic method for improving the reliability, accuracy, efficiency and/or robustness of a vehicle dynamic control system (VDCS) by providing analytical redundancy one or more sensor readings. Sensor readings such as wheel speed, yaw rate, lateral acceleration, longitudinal acceleration and steering angle are oftentimes related to another. Thus, may use these relationships detect faults in without having add additional redundant hardware complex circular logic structures, which can increase cost impose processing burdens on VDCS. In an exemplary embodiment, checks faulty through process that includes intra- inter-parameter evaluations linear forward dependencies.
