Method, device and system for controlling electrically operated gate of vehicle

The invention discloses an electrically operated gate control method, device and system for a vehicle, and the method comprises the steps: obtaining perception information according to a CAN bus; according to the sensing information, judging whether collision with a target vehicle occurs or not; if yes, determining the collision level of the collision with the target vehicle; and generating a corresponding electrically operated gate enable signal according to the collision level so as to unlock the electrically operated gate before collision. Whether the vehicle is about to collide or not and the collision level are pre-judged by collecting the information such as the vehicle speed signal, the front vehicle distance, the brake pedal opening degree and the steering wheel turning angle on the vehicle CAN bus, the vehicle door is automatically unlocked and opened according to the collision level, the harm that the vehicle door cannot be opened when the vehicle collides is avoided, and the safety of the vehicle i
