A regenerative brake system is an effective way of recovering energy that would be lost as heat during brake operation, and such systems are widely used in hybrid and electric vehicles. This paper presents a multi-objective method for allocating brake torque between the hydraulic and regenerative brake systems using model predictive control. The proposed control method has two objectives: bandwidth-based torque allocation and reduction in driveshaft vibrations. A quarter-car model with a PMSM electric drive system is used to investigate this control method’s effectiveness. The simulation results show that the vehicle stopping distance and the drive shaft vibrations will be reduced with the proposed control strategy.
