The invention belongs to the technical field of hybrid electric vehicles, and discloses a torque control method, device and equipment of a hybrid electric vehicle, a storage medium and a product. According to the method, the oil-electricity distribution torque and the front-rear axle distribution torque are determined according to the battery electric quantity corresponding to the hybrid electric vehicle, and then the engine torque, the rear motor torque and the front motor torque are determined according to the oil-electricity distribution torque and the front-rear axle distribution torque; and then threshold value judgment is conducted on the engine torque, the rear motor torque and the front motor torque, and torque control is conducted on the hybrid electric vehicle according to judgment results. According to the method, torque coordination can be carried out on the oil-electricity distribution torque and the front-rear axle distribution torque, the accurate engine torque, the accurate rear motor torque and the accurate front motor torque are obtained, and then torque control is effectively carried out on the engine, the front motor and the rear motor according to the engine torque, the rear motor torque and the front motor torque. And the hybrid electric vehicle can run smoothly in an energy-saving manner.

    本申请属于混合动力汽车技术领域,公开了一种混合动力汽车的扭矩控制方法、装置、设备、存储介质及产品。本申请根据混合动力汽车对应的电池电量确定油‑电分配扭矩和前‑后轴分配扭矩,然后根据油‑电分配扭矩和前‑后轴分配扭矩确定发动机扭矩、后电机扭矩以及前电机扭矩,再对发动机扭矩、后电机扭矩以及前电机扭矩分别进行阈值判断,并根据判断结果对混合动力汽车进行扭矩控制。本申请能够对油‑电分配扭矩和前‑后轴分配扭矩进行扭矩协调,得到准确的发动机扭矩、后电机扭矩以及前电机扭矩,再根据发动机扭矩、后电机扭矩以及前电机扭矩有效地对发动机、前电机、后电机进行扭矩控制,使混合动力汽车实现节能、平顺地运行。
