The invention relates to the field of hybrid electric vehicles, and provides a control method and device of a hybrid electric vehicle, a medium and the hybrid electric vehicle. Determining an initial motor request torque and an initial engine request torque based on the motor rotation speed change, the engine rotation speed change, the vehicle speed change, the accelerator opening degree change and the gear change; determining a target engine request torque based on a first torque difference obtained by subtracting the initial demand torque from the initial motor request torque and the initial engine request torque, so that the engine speed does not exceed a preset maximum engine speed; and a target motor request torque is determined based on the initial demand torque and the initial engine request torque, so that the rotating speed of the motor does not exceed the preset maximum rotating speed of the motor, and therefore, the power performance and the whole vehicle performance of the hybrid electric vehicle can be improved.

    本发明涉及混合动力汽车领域,提供一种混合动力汽车的控制方法、装置、介质和混合动力汽车,方法包括:获取初始需求扭矩;基于电机转速变化、发动机转速变化、车速变化、油门开度变化以及挡位变化确定初始电机请求扭矩以及初始发动机请求扭矩;基于由所述初始需求扭矩与所述初始电机请求扭矩作差得到的第一扭矩差、以及所述初始发动机请求扭矩,确定目标发动机请求扭矩,以使发动机转速不超过预设最大发动机转速;基于所述初始需求扭矩与所述初始发动机请求扭矩确定目标电机请求扭矩,以使电机转速不超过预设最大电机转速,如此可以提升混合动力汽车的动力性能和整车性能。
