Control method for power operated tailgate

Abstract

The invention discloses a method for controlling an electric tailgate, which relates to the field of control. The method comprises: driving the electric tailgate to run through an electric tailgate strut system, and determining the number of counting sensors in the nth time period of the electric tailgate running. A count value, and a second count value in the n+1th time period, calculate the count difference between the second count value and the first count value, and detect whether the count difference is within the difference range; if the count If the difference exceeds the range of the difference, the electric tailgate is controlled by the electric tailgate brace system to perform a preset anti-trap operation; the control method detects the difference between the count values ​​collected by the count sensor in two adjacent time periods. Judging whether the electric tailgate is blocked, and controlling the electric tailgate to perform anti-pinch operation when it is judged that it is blocked, the judgment time is short and the response speed is fast.

Description

technical field [0001] The invention relates to the control field, in particular to an electric tailgate control method. Background technique [0002] With the advancement of technology in the automotive field, more and more vehicles have adopted the form of electric tailgate. The user sends the door open / close command through the button in the car or the remote control key, and the control unit of the vehicle controls the drive motor to drive the tailgate to realize the tailgate. automatic switch. [0003] In order to avoid accidental accidents caused by the opening and closing of the automatic tailgate, it is usually necessary to judge whether the electric tailgate is blocked during the operation of the electric tailgate. Check whether the tailgate is blocked. When it detects that the driving motor is over-current or stalled, it will control the electric tailgate to stop running. A large torque is enough to cause great damage, so neither of these two judgment methods can...

[0003] In order to avoid accidental accidents caused by the opening and closing of the automatic tailgate, it is usually necessary to judge whether the electric tailgate is blocked during the operation of the electric tailgate. Check whether the tailgate is blocked. When it detects that the driving motor is over-current or blocked, it will control the electric tailgate to stop running. However, when the control unit detects that the driving motor has over-current or blocked, the tailgate has already generated Large torque is enough to cause great damage, so these two judgment methods cannot judge the situation of the tailgate being blocked in time, and the response time is relatively long
