| Abstract(E) | This paper studies the feasibility of using actively controlled aerodynamic devices as actuators for suppressing parasitic motions and improving handling and stability of vehicles in cornering manoeuvres. Using a three DOF vehicle model to describe the side slip, yaw and roll motion of vehicles, the LQR control design with active aerodynamic devices is optimised to track a desired yaw rate trajectory and simultaneously to suppress the parasitic rolling motion of vehicles. It is found that significant improvements in handling and dynamic stability of a base-line front wheel steered vehicle can be achieved provided the yaw and roll actuator moments are adequate. The configurations of aerodynamic actuators are considered for improving vehicle handling in cornering on motorways. |
