[0050] Step S4, the vehicle door is locked. The locking button is short pressed or the central control button 142 is pressed. The vehicle door controller 15 controls the door lock body 131 to perform a locking action.

[0051] Example Function and Effect

[0052] According to the commercial vehicle electric door, system and control method thereof involved in this embodiment, because the electric door has an electric limiter, a door lock, a switch button part and a door controller, the electric limiter can drive the door body to rotate relative to the vehicle body, the door lock includes a door lock body and a self-sucking lock, the switch button part includes an internal opening button, a central control button and an external opening button, and the door controller is respectively communicated and connected with the electric limiter, the door lock body, the self-sucking lock, the internal opening button, the central control button and the external opening button through a wiring harness, and can control the door lock body to unlock or lock when the central control button is pressed, and control the door lock body to open when the internal opening button or the external opening button is pressed, control the electric limiter to open or close the door, and control the self-sucking lock to close the door so that the door lock body is closed from a semi-locked position to a fully locked position. Therefore, this embodiment uses a button instead of a door handle of a traditional structure, and the door can be opened and closed by pressing the button, which greatly improves the convenience of use, and it is also convenient to enter and exit the vehicle when carrying items. In addition, the button structure is compact and does not protrude from the outer surface of the vehicle, which can reduce the vehicle's drag coefficient.

[0053] In addition, because the door lock also includes an external emergency unlocking assembly, the external emergency unlocking assembly contains an emergency unlocking lock cylinder, a lock cylinder rocker arm, an external emergency unlocking rod and a lock body rocker arm connected in sequence, the emergency unlocking lock cylinder is integrated on the external opening button, and the lock body rocker arm is installed on the door lock body. The emergency unlocking lock cylinder is creatively integrated on the external opening button, which can not only realize the normal button opening and closing operation of the door, but also can use mechanical methods to open the car door in emergency situations such as failure of electrical components, combining functionality and aesthetics.

[0054] In addition, because the door lock also includes an internal emergency unlocking component, which contains an internal emergency handle and an internal emergency unlocking wire, the internal emergency handle is installed on the inner side of the door body, and the two ends of the internal emergency unlocking wire are respectively connected to the internal emergency handle and the door lock body, the car door can be quickly unlocked in an emergency, thereby improving safety.

[0055] In addition, because the commercial electric door system also includes a remote control key, which has an unlock button and a lock button, only two buttons of the remote control key are required. By distinguishing between short presses and long presses of the buttons, four operating instructions, namely door opening, door closing, door lock unlocking, and door lock locking, can be executed. This can not only simplify the remote control key design, but also greatly improve the user experience of the driver and passengers.

[0056] The above-mentioned embodiments are preferred examples of the present invention and are not intended to limit the protection scope of the present invention.
