A Control Strategy of Regenerative Braking System with Motor ABS for In-Wheel-Motor Vehicle

The electro-mechanical braking system of In-Wheel-Motor vehicle is analyzed by applying vehicle braking stability theory. Considering the properties of composite lectro-mechanical braking system, a regenerative braking system control strategy with ABS function for In-Wheel-Motor vehicle is proposed. In the strategy, the ABS function is achieved by adjust the motor torque. With using the new strategy, simulations are conducted on an in-wheel-motor vehicle model, and the road adhesion coefficient in the simulation is 0.2 and 0.8 respectively. The result shows that the control strategy proposed enhances the braking stability of In-Wheel-Motor vehicle.
