FAULT DETECTION METHOD OF ACTIVE GEOMETRY CONTROL SUSPENSION

摘要

A fault detecting method of an active geometry control suspension is provided to detect the fault of AGCS simply by software without mounting any additional mechanical devices. A fault detecting method of an active geometry control suspension includes the steps of receiving wheel speed and steering angle, obtaining an estimated yaw rate and estimated lateral acceleration according to the received wheel speed and steering angle(S210), controlling a bump toe angle according to the estimated lateral acceleration, receiving a measured yaw rate and a measured lateral acceleration, and determining the fault of the AGCS according to the comparison between the estimated and measured values.
