Problems solved by technology

However, with the aging or wear of the various parts of the window, the anti-pinch force set at the factory can no longer guarantee its anti-pinch function. It is necessary to revise the anti-pinch force of the electric window regularly, which will increase the maintenance cost and is not conducive to the anti-pinch function. Promotion of clamping electric windows

Embodiment Construction

[0016] The object of the present invention is to provide a control method for anti-pinch electric vehicle windows, which can solve the change of self-adaptive anti-pinch force when the performance of the vehicle window changes. It solves the problem of different anti-pinch force for a single window. After the window is installed, it learns the anti-pinch force automatically, and uses different anti-pinch force for different windows. It solves the misjudgment of the anti-pinch force of the window caused by the difference in the rising resistance of the window. Fixed window manual restart anti-pinch algorithm after maintenance.

[0017] In the invention, the anti-pinch force of the vehicle window is learned for the first time when the vehicle window is assembled successfully, and the anti-pinch force is judged during the automatic rising process, and then the reference force is judged and updated.

[0018] Such as figure 1 As shown, after the window controller is installed on ...

Abstract

The invention discloses a control method for an anti-pinch electric vehicle window. The control method is characterized in that a variation range of anti-pinch force is divided into 40 relatively independent intervals by the control method, wherein each interval corresponds to an anti-pinch force; the position of the vehicle window and the interval of the anti-pinch force are initialized; whether ascending resistance meets basic resistance or not is judged during ascending of the vehicle window; when the ascending resistance meets the basic resistance, the ascending resistance is stored; and whether the reference force and the anti-pinch force of the vehicle window are updated or not is judged. Since the structure is adopted, the variation in the anti-pinch force can be automatically adapted when the performance of the vehicle window varies.

Description

technical field [0001] The invention relates to the field of automatic control of automobiles, in particular to a control method for anti-pinch electric vehicle windows. Background technique [0002] As automobile safety is paid more and more attention by people, the traditional electric windows cannot meet people's safety requirements. Since the anti-pinch electric window can effectively prevent accidental injury to the human body during the rising process of the window, it is more and more widely used in various cars, and has become the development trend of car windows, and has also become the standard configuration of high-end cars. [0003] Existing anti-pinch electric vehicle windows are all set and fixed before leaving the factory to the control of anti-pinch force. However, with the aging or wear of the various parts of the window, the anti-pinch force set at the factory can no longer guarantee its anti-pinch function. It is necessary to regularly revise the anti-pin...
