The invention discloses a hybrid mode switching method and device, electronic equipment and a medium. The method comprises the steps that the target driving wheel speed, the current engine rotating speed and the current engine torque are obtained; determining a target engine rotating speed based on the target driving wheel speed and the target speed ratio; determining a rotating speed difference value, and determining a current engine acceleration corresponding to the current engine rotating speed; if it is detected that the rotating speed difference value is smaller than a preset rotating speed threshold value and the current engine acceleration is smaller than a preset acceleration threshold value, the clutch torque is controlled based on a pre-calibrated clutch combination slope; determining a target generator torque based on the rotating speed difference value and a corresponding relation between the rotating speed difference value and the generator torque, and determining a target total torque based on the target generator torque and a preset offset torque; and if it is detected that the clutch torque is larger than the target total torque, the target vehicle is switched from the serial driving mode to the parallel driving mode, and therefore more stable hybrid mode switching operation can be conducted on the vehicle.

    本发明公开了一种混动模式切换方法、装置、电子设备和介质。该方法包括:获取目标驱动轮轮速、当前发动机转速和当前发动机扭矩;基于目标驱动轮轮速和目标速比,确定目标发动机转速;确定转速差值,并确定当前发动机转速对应的当前发动机加速度;若检测到转速差值小于预设转速阈值,且当前发动机加速度小于预设加速度阈值,则基于预先标定的离合器结合斜率控制离合器扭矩;基于转速差值和转速差值与发电机扭矩之间的对应关系,确定目标发电机扭矩,并基于目标发电机扭矩与预设偏移扭矩确定目标总扭矩;若检测到离合器扭矩大于目标总扭矩,则将目标车辆从串行驱动模式切换至并行驱动模式,从而可以对车辆进行更平稳地混动模式切换操作。
