An electromechanical flywheel hybrid power system driving control method belongs to the field of electric vehicle control and is characterized in that a hybrid power system can be controlled to operate in various driving modes according to vehicle operation conditions. Under low driving power, the second power source motor is controlled to participate in vehicle driving, so that the economy of thevehicle can be improved; under medium driving demand power, the first power source motor and the second power source motor are controlled to jointly drive the vehicle to run, and the vehicle energy utilization efficiency is improved; and under high driving demand power, the first power source motor, the second power source motor and the flywheel are controlled to jointly drive the vehicle to run,the instantaneous high-power output advantage of the flywheel is utilized, large-amplitude fluctuation of motor and battery power under the working conditions of large load and sudden load change isreduced, so that the service life of a battery is prolonged.

    一种机电飞轮混合动力系统驱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,控制混合动力系统运行于多种驱动模式。低驱动功率下,通过控制第二动力源电机参与车辆驱动,可提高车辆的经济性;中等驱动需求功率下,控制第一动力源电机与第二动力源电机联合驱动车辆行驶,提高了车辆能量利用效率;高驱动需求功率下,控制控制第一动力源电机、第二动力源电机和飞轮三者联合驱动车辆行驶,利用飞轮瞬时高功率输出优势,降低大负荷以及负载突变工况下电机以及电池功率大幅波动,延长了电池的使用寿命。
