Abstract: A Layered Coordinated Control (LCC) strategy for chassis system that is divided into upper and bottom layer control parts is proposed. The bottom controllers are made up of three separate controllers, i.e. suspension, steering and braking systems. Each of them is used to carry out different control tasks and to achieve performance indices of subsystems. The Upper Coordinated Controller receives information coming from chassis system and modifies the decision-making of bottom controllers, aiming at improving whole vehicle synthesis performance. To demonstrate the performance of our proposed method, it is implemented under the MATLAB/SIMULINK software environment, and the simulation results show that chassis system based on LCC strategy is able to achieve better ride comfort, more security and higher handling stability than that of the commonly used single layered control one.
