[0120] like Figure 9 As shown, the present invention provides a second embodiment of the electric tailgate speed control method, including:
[0121] Step S301: The electric tailgate enters the manual state from the control command of the stop state, and determines whether the manual state is the manual open state? If it is in the manual open state, then enter step S302;
[0122] Step S302: When the manual state is the manual open state, judge whether the current position of the electric tailgate has reached the preset opening threshold; if the current position of the electric tailgate has not reached the preset opening threshold, enter Step S303, if the current position of the electric tailgate reaches the preset opening threshold, go to step S305;
[0123] like Figure 10 As shown, it is a schematic diagram of the preset dividing point of the electric tailgate, and the preset opening dividing point is a position 10° away from the maximum position point.

[0129] like Figure 11 As shown, the present invention provides a third embodiment of the electric tailgate speed control method, including:
[0130] Step S401: The electric tailgate enters the manual state from the control command of the stopped state, and determines whether the manual state is the manually closed state? If it is in the manual closing state, enter step S402;
[0131] Step S402: When the manual state is the manual closing state, judge whether the current position of the electric tailgate has reached the preset closing threshold; if the current position of the electric tailgate has not reached the preset closing threshold, enter Step S403, if the current position of the electric tailgate reaches the preset closing threshold, go to step S405;
[0132] like Figure 10 As shown, it is a schematic diagram of the preset dividing point of the electric tailgate, and the preset closing dividing point is a position 20° away from the minimum position point.

Abstract
The invention provides a speed control method and device for an electric tail gate. The speed control method for the tail gate is applied to the electric tail gate in a manual operation process and includes the following steps: S1, judging whether a first control variable of the electric tail gate is larger than a manual operation threshold value or not, S2, conducting brake control on the electric tail gate if the first control variable of the electric tail gate is larger than the manual operation threshold value to ensure that the control variable of the electric tail gate is not larger than the manual operation threshold value in the manual operation process and a mechanical supporting structure is not damaged, S3, making brake measures instantly in a manually opened state when the electric tail gate is close to an extreme position, S4, reducing the speed of the electric tail gate to zero to protect the mechanical structure of the electric tail gate, S5, judging whether the control variable of the electric tail gate is larger than a manual-lock brake threshold value or not when the electric tail gate is in a manual-lock state, and S6, conducting brake control if the control variable of the electric tail gate is larger than the manual-lock brake threshold value to prevent the electric tail gate from smashing into a gate lock and damaging the mechanical structure. According to the speed control method for the electric tail gate, the speed of the electric tail gate is guaranteed to be stable and a user can use the electric tail gate safely when the user opens or closes the electric tail gate manually too fast.
Description
technical field [0001] The invention relates to the field of automation, in particular to a method and device for controlling the speed of an electric tailgate. Background technique [0002] With the advancement of technology in the automotive field and the continuous improvement of the quality of life of human beings, cars have become an indispensable means of transportation for human beings to go out. Humans will inevitably carry items when they go out, and use the tailgate of the car to load and unload items. In order to facilitate human beings Using the tailgate of the car, the tailgate of many cars has been changed to an electric state. Humans send control commands to the tailgate of the car through the remote control switch, and the tailgate of the car receives the control command and controls the tailgate of the car to open or close automatically through the program. The tailgate controlled by the control command is called the electric tailgate, the process of the ele...
