The invention relates to a vehicle power system control method and device, computer equipment and a storage medium. The method comprises the steps that the states of a clutch are determined according to the position of the clutch, and the states of the clutch comprise the separation state, the sliding friction state and the combination state; according to the vehicle operation parameters and the target vehicle operation parameters, the first request torque of the engine and the second request torque of the power motor are determined when the clutch is in the separation state, the sliding friction state and the combination state; adjusting the torque of the engine according to the first request torque, and adjusting the torque of the power motor according to the second request torque. Therefore, the torque of the engine and the torque of the power motor at each moment can be controlled in the mode switching process of the vehicle, so that the torque of the vehicle cannot suddenly change and cannot become zero, the smoothness of torque change in the mode switching process of the vehicle is improved, the stability of the vehicle is improved, and the comfort degree of the vehicle is improved.

    本申请涉及一种车辆动力系统控制方法、装置、计算机设备和存储介质。该方法包括:根据离合器的位置,确定离合器的状态,离合器的状态包括分离状态、滑摩状态、结合状态;根据车辆运行参数、目标车辆运行参数,分别确定在离合器处于分离状态、滑摩状态、结合状态时的发动机的第一请求扭矩和动力电机的第二请求扭矩;根据第一请求扭矩,调整发动机的扭矩,根据第二请求扭矩,调整动力电机的扭矩。从而能够在车辆切换模式的过程中,对每一时刻的发动机扭矩和动力电机的扭矩进行控制,使得车辆的扭矩不会发生突变,也不会变为0,提高车辆在切换模式的过程中扭矩变化的平顺度,提高车辆的平稳性,进而提高车辆的舒适度。
