A seven-degree-of -freedom model of the vehicle with crosswind and actuator failure is built to obtain the information of the actual actuator failure. In order to realize the actuator FD of the ESC system in the presence of crosswind interference, a differential homeomorphic transformation is executed so that the undetectable interference is transformed into the measurable input of the system. Subsequently, the observer for actuator FD is proposed corresponding to the transformed system. The actuator fault can be positioned on a certain wheel by the residual, and the actual actuator failure estimation is obtained. The effectiveness of the method is verified by simulation.
