The invention discloses a torque distribution method, device, equipment and medium under the parallel working condition of a hybrid power system, and the method comprises the steps that when a hybrid power vehicle is in the parallel state of direct driving of an engine, the operation working condition of the vehicle is determined; when the vehicle is in the cruise working condition, controlling a driving motor to output zero torque and controlling an engine to output positive torque to drive the vehicle according to the target torque of the whole vehicle, or controlling the driving motor and the engine to jointly output the positive torque to drive the vehicle; when the vehicle is in the braking working condition, the driving motor is controlled to reduce the output torque to zero, and the generator is controlled to output the negative torque with the target that the whole vehicle driving torque is smaller than or equal to zero, so that the positive torque output by the engine and the driving motor is counteracted; when the vehicle is in the cruising working condition and the braking working condition, the driving motor is kept in the positive torque output state or the zero torque output state, perceptible whole vehicle shaking caused by zero passage of the torque of the driving motor in the regenerative braking process is avoided, and the driving feeling of the whole vehicle in the high-speed cruising process is improved.

    本发明公开了一种混动系统并联工况时的扭矩分配方法、装置、设备及介质,该方法包括当混动车辆处于发动机直接驱动的并联状态时,确定车辆的运行工况;当车辆处于巡航工况时,根据整车目标扭矩控制驱动电机输出零扭矩且控制发动机输出正扭矩驱动车辆,或者控制驱动电机和发动机共同输出正扭矩驱动车辆;当车辆处于制动工况时,控制驱动电机将其输出扭矩降低到零,并以整车驱动扭矩小于或等于零为目标控制发电机输出负扭矩,以抵消发动机和驱动电机输出的正扭矩,实现了在整车进入并联后,车辆在巡航工况和制动工况时驱动电机均保持在输出正扭矩状态或者零扭矩状态,避免了在回馈制动时驱动电机扭矩过零导致可感知的整车抖动,提高了整车高速巡航时的驾驶感受。
