To the hybrid electric vehicle in the adhesion coefficient road to start or in low speed under engine participation mode, prevent the generation of a greater additional yaw moment and affect the stability of the vehicle, coordinated control strategy of engine and motor unit hydraulic brake based on multi-target dynamic coordinate control is proposed. According to the characteristics of the hybrid vehicle, the force model of the vehicle driving wheel was built, and the control strategy was formulated based on the inverse model of the hydraulic brake torque control algorithm and the engine target torque design. Based on Simulink simulation, the simulation results of hybrid electric vehicle control system in the hydraulic b-+rake coordination control strategy of the engine were analyzed. The results show that this method can improve the vehicle's acceleration performance, and more effectively inhibit the low adhesion side drive wheel slip.
