The invention discloses a torque distribution method and device, a controller, a vehicle and a medium. The method comprises the steps that target demand feedback torque is determined according to a deceleration signal of the vehicle; when the vehicle battery is in the feedback charging power limited state, a target torque distribution type with the lowest overall feedback efficiency is determined; and executing torque distribution operation according to the target torque distribution type and the target demand feedback torque. According to the invention, the feedback power for charging the vehicle battery is reduced, the risks of battery overcharge and the like caused by the limitation of the maximum allowable charging power of the battery are effectively relieved, the service life of a brake disc is prolonged, and the braking safety is improved.
本发明公开了一种扭矩分配方法、装置、控制器、车辆和介质,该方法包括:根据车辆的减速信号确定目标需求回馈扭矩;当车辆电池处于回馈充电功率受限状态时,确定整体回馈效率最低的目标扭矩分配类型;根据所述目标扭矩分配类型以及所述目标需求回馈扭矩执行扭矩分配操作。本发明减少了用于对车辆电池进行充电的回馈功率,有效缓解了由于电池的最大允许充电功率的受限而带来的电池过充等风险,延长了制动盘寿命,提升了制动安全。
