防止误进换电模式溜坡方法、装置、系统和车辆

The invention discloses a method, a device, a system and a vehicle for preventing a power conversion mode from sliding down by mistake, wherein the method comprises the steps of acquiring a trigger signal of a user on a power conversion soft switch from an instrument, establishing a communication link with a power conversion station according to the trigger signal, and transmitting a power conversion intention to the power conversion station through the communication link; and after determining that the execution of the power switching intention meets the ASIL A safety level, sending a power switching request to the electronic parking brake mechanism by using the whole vehicle controller conforming to the ASIL B safety level, and controlling the electronic parking brake mechanism to determine whether a driver is positioned in the vehicle or not through a sensor conforming to the ASIL A safety level, wherein when the driver is not positioned in the vehicle, the electronic parking brake mechanism does not respond to the power switching request so as to maintain the clamping state of the calipers. According to the invention, before releasing the calipers, whether the driver is in the car or not is detected, so that the condition of sliding a slope caused by the fact that the car enters a power conversion mode by mistake is avoided. The safety of the whole vehicle is improved. The invention is mainly used in the technical field of vehicles.
