Technical Field
The invention relates to an automobile electric control technology, in particular to an automobile electric window control technology.
Background
At present, the automatic lifting function of the electric window is well developed in the automobile industry, the realization of the electric window also brings convenience for drivers and passengers, but some unsolved defects exist, such as the passenger is damaged by the automatic window, and the automobile flameout window is not closed, so that financial loss is caused. In order to solve the problems, previous researches provide some solutions, such as an anti-pinch technology based on a hall sensor, a non-contact type car window anti-pinch technology based on infrared detection, and a technology of judging whether a car window is automatically closed or not after whether a person exists in the car is judged based on a pressure sensor.
Prevent pressing from both sides hall sensor's hall signal that hall sensor just produced when needing to detect window motor rotation based on hall sensor, realize the door window through analysis hall signal and prevent pressing from both sides the function.
Non-contact door window anti-pinch technology based on infrared detection utilizes infrared light to form the light curtain on the door window frame, and when the appearance shelters from the thing, the light intensity of receiving can change. Whether the car window meets an obstacle in the ascending process or not is identified according to the principle, and an anti-pinch effect is achieved.
The technology of judging whether a vehicle window is automatically closed or not after whether a person exists in the vehicle or not is judged based on the pressure sensor, and whether a passenger exists in the vehicle body or not is detected by mounting the pressure sensor on the cushion, so that whether the vehicle window is closed or not is judged.
However, most of existing electric windows cannot realize one-key window control, so that people or hands are clamped in the electric windows, and financial loss can be caused when an owner forgets to close the electric windows after an automobile is shut down.
