Abstract :
Split-mu braking means that a vehicle brakes on a road surface with left right dissymmetrical friction coefficient. For most drivers, a heavy braking on split-mu road surface will cause vehicle to skid or spin or lose the steering control. In this paper, an active front steering control was designed to improve the maneuver stability while braking on split-mu road surface with four-channel Anti-lock Braking System which will produce an additional yaw torque to let the vehicle deviate from the straight direction but can achieve maximum braking force. A multi-body vehicle model was built to simulate and analyze the vehicle dynamics performance during braking on split-mu road surface. The simulation results show that the new control system integrated with active front steering and four-channel ABS can improve the vehicle lateral stability on split-mu road surface braking.
