Problems solved by technology

[0004] The existing car window control method has the following problems. If it is in the cold winter, the hardness of the car window seal will increase, resulting in an increase in the running resistance of the car window. The current of the window increases, and when it reaches the stall threshold of the window motor, the window control module controls the window motor to turn off, causing the window to fail to open or close normally

Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0042] In existing cars, the window motor is driven by the window control module, and the window control module drives and outputs a constant current value, that is, the driving current of the window motor is constant, that is, the output power of the window motor is constant. When the hardness of the window seal increases , leading to an increase in the running resistance of the window, and the output power of the window motor is not enough to drive the window...

Abstract

The invention provides an automobile window motor control method and system and an automobile. The current environment temperature value is obtained, and whether the current environment temperature value is lower than a preset temperature threshold value or not is judged; and when it is judged that the current environment temperature value is lower than the preset temperature threshold value, a driving circuit is controlled to increase a driving current so as to increase a working current of an automobile window motor. By increasing the driving current, the output power of the automobile window motor is increased correspondingly to enough drive an automobile window to overcome operation resistance, so that clamping is avoided, the situation that clamping of the automobile window causes rotating blocking of the automobile window motor, so that the current in the circuit is increased rapidly to reach the rotating blocking threshold value of the automobile window motor is further avoided, and namely, smooth opening or closing of the automobile window in a cold environment can be achieved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of automobile engineering, in particular to a method and system for controlling a window motor and an automobile. Background technique [0002] With the increasing popularity of automobiles, the development of automobile technology is more and more reflected in the field of automobile electronics to enhance the comfort and safety of automobiles. Among them, electric windows have become the standard configuration of most cars. [0003] At present, the vehicle window control method usually drives the window motor by the window control module, and the window control module drives the output constant current value, and the window operates normally. When the window rises to the roof, the current value increases to exceed the threshold value. The window control module determines that the window motor is blocked and stops. [0004] The existing car window control method has the following...
