Embodiment Construction

[0025] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0026] In order to make car owners use the electric tailgate more conveniently and safely, the basic idea of ​​the present invention is to use the electric tailgate ECU device based on the CAN bus to open and close the vehicle tailgate through the vehicle key switch or the remote control key. The tailgate switch is installed to open and close the tailgate, and the tailgate can only be opened when the vehicle is cut into the parking gear (P gear) and the speed is zero; in addition, when the tailgate is opened and closed, it is detected by the obstacle set in the support motor The unit detects the surrounding environment of the tailgate. When an obstacle is detected, the motor of the strut bar is controlled to stop or reverse the motor, which has the function of anti-clamping, which will greatly improve the s...

Abstract

The invention discloses an electric tail gate ECU device and control method based on CAN bus. The device comprises a central processing unit, and the device further comprises a CAN bus processing unit, a jackstay motor control unit, a self-absorption motor control unit, an obstacle detection unit, a locking detection unit, a tail gate signal detection unit, a keying unit and an alarm unit. The method comprises the step of controlling a tail gate to be opened and closed according to vehicle state information, tail gate ascending and descending environment information, tail gate locking state information and tail gate open-closed state information. According to the electric tail gate ECU device and control method based on the CAN bus, by obtaining vehicle CAN bus information and utilizing various sensors for judging the vehicle state, the tail gate is controlled to be opened, closed and locked automatically according to the vehicle state, so that the vehicle tail gate is opened and closed in a safe and reliable mode, more humanization and intelligentization are achieved, use by a user is facilitated, user experience is improved, and good economic and social benefits are achieved. The device can be widely applied to automated control systems of various vehicle tail gates.

Description

technical field [0001] The invention relates to the field of vehicle automation control, in particular to an automatic control device and control method for an electric tailgate. Background technique [0002] ECU: Electronic Control Unit, electronic control unit, also known as "driving computer", "vehicle computer" and so on. [0003] CAN bus: ControllerAreaNetwork, controller area network, was developed by German BOSCH company, which is famous for R&D and production of automotive electronic products, and eventually became an international standard (ISO11898), which is one of the most widely used field buses in the world. [0004] In modern cars, the electric tailgate function has become a highlight of high-end and high-end vehicles. Some vehicles have a higher ground clearance after the tailgate is opened, and female car owners and some short male car owners have difficulty opening and closing the tailgate, and some vehicles have a relatively large tailgate torque, which i...
