The invention relates to the technical field of power control, in particular to a torque distribution method, device and equipment under a carbon load overload fault and a medium, and aims at solving the problem that the dynamic property of a hybrid vehicle is low after a DPF overload fault occurs. When the first output torque of the engine is larger than the output torque limit value, the battery electric quantity of the hybrid vehicle and the state value of each operation parameter of the motor are obtained; if the battery electric quantity is larger than the preset electric quantity and the state value of each operation parameter is smaller than the corresponding limit value, the target torque of the engine is determined based on the output torque limit value, and the target torque of the motor is determined based on the first output torque, the output torque limit value and the second output torque of the motor; controlling the engine to output the target torque of the engine, and controlling the motor to output the target torque of the motor; in this way, the overall dynamic property of the hybrid vehicle can be improved by improving the output power of the motor.

    本申请涉及动力控制技术领域,尤其涉及碳载量过载故障下的扭矩分配方法、装置、设备及介质,用于解决混动车辆发生DPF过载故障后动力性低下问题,该方法为:在确定混动车辆的发生碳载量过载故障,且发动机的第一输出扭矩大于输出扭矩限值时,获取混动车辆的电池电量,以及电动机的各运行参数的状态值;若电池电量大于预设电量,且各运行参数的状态值均小于对应限值,则基于输出扭矩限值确定发动机的目标扭矩,以及基于第一输出扭矩、输出扭矩限值和电动机的第二输出扭矩,确定电动机的目标扭矩;控制发动机输出前述发动机的目标扭矩,以及控制电动机输出前述电动机的目标扭矩;这样,可以通过提高电动机输出功率,提高混动车辆整体的动力性。
