The invention discloses a parallel system torque distribution method and device, equipment and a medium. The method comprises the steps that the current total demand torque and the current total actual response torque are obtained; calculating an absolute value of a first difference value between the current total demand torque and the current total actual response torque; when the absolute value of the first difference value is larger than the preset value, the engine demand torque is distributed to be a second difference value between the current total demand torque and the current actual motor torque; when the absolute value of the first difference value is smaller than the preset value, the engine demand torque is distributed to be a third difference value between the current total demand torque and the current motor demand torque; wherein the current motor demand torque is obtained according to the current total demand torque, the actual rotating speed of the motor and the torque distribution calibration map. And furthermore, by comparing the current total demand torque with the current total actual response torque and adopting different torque distribution methods, the final torque distribution value sum of the motor and the engine is consistent with the intention of the driver as much as possible, so that the intention of the driver is met.
本发明公开了一种并联系统扭矩分配方法、装置、设备和介质,方法包括:获取当前总需求扭矩和当前总实际响应扭矩;计算当前总需求扭矩和当前总实际响应扭矩之间的第一差值的绝对值;当第一差值的绝对值大于预设值时,分配发动机需求扭矩为当前总需求扭矩与当前电机实际扭矩的第二差值;当第一差值的绝对值小于预设值时,分配发动机需求扭矩为当前总需求扭矩与当前电机需求扭矩的第三差值;其中,当前电机需求扭矩根据当前总需求扭矩、电机实际转速、扭矩分配标定map得到。进而,通过对比当前总需求扭矩和当前总实际响应扭矩之间的大小,采用不同的扭矩分配方法,使得最终电机与发动机的扭矩分配值总和尽量与驾驶员意图相一致,从而满足驾驶员意图。
