The invention discloses an automatic switching system and method for driving modes of an oil-electric hybrid vehicle. The automatic switching system comprises a VCU module connected with the oil-electric hybrid vehicle. A hybrid power mode, a fuel oil mode, a pure electric mode and a parking charging mode are arranged in the VCU module; the vehicle runs in the default hybrid mode, the motor participates in driving when the vehicle is started in the hybrid mode, and the engine participates in driving again when the vehicle reaches a certain speed. When the power supply battery of the vehicle fails and cannot be applied to high voltage, the power supply battery is closed and automatically switched to a fuel oil mode; in the pure electric mode driving process, when the electric quantity of a power supply battery is lower than 30%, an engine is involved, and the hybrid mode is automatically switched; when the electric quantity of a power supply battery is lower than 20% in the hybrid power mode running process, the fuel oil mode is automatically switched; or when the temperature of the power supply battery or the VCU module or the vehicle-mounted controller exceeds the upper limit when the vehicle is in the pure electric mode or the hybrid mode, the power supply battery is closed, and the vehicle is automatically switched to the fuel oil mode; and the driving is more intelligent.

    本发明公开了一种油电混动车辆行驶模式自动切换系统及方法,包括连接油电混动车辆的VCU模块;VCU模块内设置有混动模式、燃油模式、纯电模式以及驻车充电;本发明通过在车辆默认混动模式运行,混动模式下车辆起步时电机参与驱动,车辆达到一定速度时,发动机再参与驱动。当车辆供电电池出现故障无法上高压时,供电电池关闭,自动切换为燃油模式;纯电模式行驶过程中,供电电池电量低于30%时,发动机介入,自动切换为混动模式;混动模式行驶过程中供电电池电量低于20%时,自动切换为燃油模式;或在当车辆处于纯电模式或者混动模式下供电电池或VCU模块或车载控制器温度超过上限时,供电电池关闭,自动切换为燃油模式;使驾驶更智能。
