Integrated vehicle chassis control based on direct yaw moment, active steering and active stabiliser

In order to coordinate steering. braking/traction and active stabiliser. an integrated vehicle Chassis controller is proposed. The controller is realised via a main/servo-loop structure: in the main-loop. stabilising forces/moments are first calculated using robust sliding mode controller: then in the servo-loop. the stabilising forces/moments are optimally distributed to tyre control input, i.e. active steering and wheel torques. To reduce body roll angle and assist to track the desired yaw rate, active stabilisers arc further integrated. Through open-loop and closed-loop simulations Using Matlab/Simulink (R) and MSC CarSim (R), it is verified that the controller can significantly improve vehicle handling performances and ride in comfort in the meantime.
