Embodiment Construction
[0074] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.
[0075] refer to figure 1 , is a flow chart of an anti-pinch control method provided in the embodiment of the present application. This method is applicable to an electronic control unit for electronically controlling the tailgate, such as an electronic control unit for a tailgate of a car, etc., and is mainly used for controlling the tailgate. Anti-pinch detection and control.
[0076] Specifically, the anti-pinch control method in this embodiment may include the following steps: ...

The present application discloses an anti-pinch control method and device. The method includes: during the closing process of the tailgate of the automobile, continuously obtaining the motor current corresponding to the tailgate; based on the continuously obtained motor current, determining the The current working condition and the anti-pinch threshold corresponding to the current working condition; when the current change information of the motor current matches the anti-pinch threshold, control the tailgate to move in the opposite direction. It can be seen that in this application, the current working condition of the car is determined based on the motor current during the tailgate closing process, and the current change information of the motor current is matched and judged by using the corresponding anti-pinch threshold in the current working condition, and then When it is judged that the tailgate encounters an obstacle, that is, when the current change information matches the anti-pinch threshold, it can accurately control the movement of the tailgate in the opposite direction, thereby realizing the anti-pinch control of the tailgate and effectively preventing the user from being pinched by the tailgate .
Description
technical field [0001] The present application relates to the technical field of automotive electronics, in particular to an anti-pinch control method and device. Background technique [0002] With the rapid development of automotive electronic technology, more and more cars use electronic control units to realize the opening and closing of the tailgate. In order to ensure the safety of the user, the car tailgate under the electronic control unit needs to judge whether the tailgate encounters an obstacle when closing, so as to effectively prevent the user from being pinched by the electric tailgate. [0003] At present, by judging the change of the tailgate motor current when the tailgate is closed, and then controlling the reverse movement of the tailgate in time when it is judged that the tailgate encounters an obstacle, so as to prevent being pinched by the tailgate. [0004] However, when the tailgate is closed, the car may be in various working conditions, resulting in...
