The invention discloses a vehicle control mode switching method and device, electronic equipment and a storage medium. The method comprises the steps of determining a target control mode and calculating a target engine torque and a target motor torque when it is determined that a current control mode meets a mode switching condition according to a vehicle demand torque, a current engine torque, a current engine rotating speed and a current battery electric quantity; the difference value between the current engine torque and the whole vehicle demand torque is calculated, the motor compensation torque in the mode switching process is determined, and the current engine torque is compensated; and the current motor torque is obtained, when it is determined that the target control mode meets the switching ending condition according to the current engine torque, the current motor torque and the motor compensation torque, the target control mode is switched to, and an engine and a motor of the current vehicle are controlled. According to the technical scheme, the stability and smoothness of the vehicle mode switching process of the hybrid electric vehicle are improved.

    本发明公开了一种车辆控制模式切换方法、装置、电子设备及存储介质。该方法包括:在根据整车需求扭矩、当前发动机扭矩、当前发动机转速和当前电池电量,确定当前控制模式满足模式切换条件时,确定目标控制模式,计算目标发动机扭矩和目标电机扭矩;计算当前发动机扭矩和整车需求扭矩之间的差值,确定模式切换过程中的电机补偿扭矩,对当前发动机扭矩进行补偿;获取当前电机扭矩,在根据当前发动机扭矩、当前电机扭矩和电机补偿扭矩,确定目标控制模式满足结束切换条件时,切换至目标控制模式,对当前车辆的发动机和电机进行控制。本发明实施例的技术方案提高了混动汽车的车辆模式切换过程的稳定性和平顺性。
