The invention discloses a dual-motor single-flywheel hybrid power system brake control method, and belongs to the field of electric vehicle control. The method is characterized in that working modes such as single-motor driving, dual-motor driving, flywheel driving and dual-motor driving can be realized according to vehicle operation conditions, under low brake demand power, the single motor is controlled to participate in regenerative braking, the energy recovery rate can be increased, the dual motors or flywheels and the motors are controlled to participate in regenerative braking of the vehicle under the medium braking demand power, the dual motors and the flywheels are controlled to participate in regenerative braking of the vehicle under the high braking demand power, the running process of the vehicle is increased, and the economy of the vehicle is improved.

    一种双电机单飞轮混合动力系统制动控制方法属于电动汽车控制领域,其特征在于能够依据车辆运行工况实现单电机、双电机、飞轮与双电机驱动等工作模式,低制动需求功率下,控制单电机参与再生制动,可提高能量回收率,中等制动需求功率下,控制双电机或飞轮与电机参与车辆的再生制动,高制动需求功率下,控制双电机与飞轮三者一起参与车辆的再生制动,增加了汽车的行驶历程,提高了车辆的经济性。
