The invention discloses a control method, device and equipment of a range extending system and a vehicle. The method comprises the steps that it is detected that the range extending system works at a preset power point; the initial torque distributed to the second motor, the third motor and the fourth motor is controlled to be one fourth of the net torque output by the engine; obtaining a calculation difference value between the actual torque and the initial torque of the first motor; if the absolute value of the calculated difference value is larger than the first threshold value, the torque distributed to the second motor, the third motor and the fourth motor is adjusted according to the calculated difference value, so that the calculated difference value is within the preset range. According to the embodiment of the invention, the torque of the four motors can be dynamically adjusted, so that the torque difference is within the preset range, power generation is balanced, torque balance among the motors is automatically realized, mechanical stress is more balanced, mechanical loss caused by torque imbalance is reduced, and the service life is prolonged.
本发明公开了一种增程系统的控制方法、装置、设备及车辆,该方法包括:检测到增程系统在预设功率点工作;控制分配给第二电机、第三电机以及第四电机的初始扭矩均为发动机输出的净扭矩的四分之一;获取第一电机的实际扭矩与初始扭矩的计算差值;若计算差值的绝对值大于第一阈值,则根据计算差值调整分配给第二电机、第三电机以及第四电机的扭矩,使得计算差值在预设范围内。本发明实施例能够动态调整四个电机的扭矩,使得扭矩差距在预设范围内,进而均衡发电,自动实现电机间的扭矩均衡,使得机械受力更平衡,减小扭矩不均衡带来的机械损耗,延长使用寿命。
