Abstract: With the intelligent development of chassis, the conflicts between chassis systems become more and more obvious. In order to solve the system conflict of chassis, a layered integrated control is designed to control all chassis systems. According to the function, there are many layers of control, including signal processing, state estimation, control target calculation, vehicle control, control allocation, and each system control. The control objectives of the vehicle are determined according to the state of the vehicle and the operation of the driver, and the control objectives are uniformly assigned to each system according to the execution ability of each system, so as to meet the vehicle control objectives. It is concluded that the integrated chassis control can effectively extend the lateral linear zone of the vehicle, reduce the response delay of the vehicle and improve the overshoot in the transient to steady transition of the vehicle. Therefore, the development of integrated chassis control technology can give full play to chassis performance, optimize chassis control architecture, and make the overall control architecture clearer and more concise communication.
