Embodiment Construction

[0017] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. This system includes the following aspects.

[0018] Aspect 1, module: the control object of the window control system is the window, which can refer to the windows on the left and right sides of the vehicle body, of course, it can also refer to windows at other positions on the vehicle such as the sunroof. In this embodiment, the windows on the left and right sides of the vehicle body are taken as an example. The functional module diagram of this system is as follows: figure 1 shown.

[0019] The basic module diagram of the system is as follows: figure 2 shown. Among them, the microprocessor uses the powerful STM32 chip as the first choice to control Hall sensors, DC motors, etc. Vehicle power supply, power management module provides power for microcontrollers, voice recognition modules, infrared sensors, etc. The specific hardware composi...

Abstract

The invention discloses a car window anti-pitch self-inspection control system and method. The method comprises the steps that the car window displacement height is measured by adopting a hall pulse counting method and combining with a current ripple pulse measuring method, an infrared sensor measuring displacement method and a multi-channel mutual compensation method; according to the more accurate car window displacement data after comprehensive correction, the basis for judging whether the car window enters the anti-pitch area or not and whether the car window rises to the top or not afteran engine is turned off is obtained; and combined with infrared detection and speech recognition, anti-pitch warning is achieved in advance, and after the engine is turned off, whether the car windowis closed or not is checked according to the current reserved window displacement information.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a window anti-pinch self-check control system and method. Background technique [0002] As more and more cars install electric doors, windows and sunroofs, potential dangers also follow. Incidents of electric doors and windows pinching fingers happen from time to time. The safety of the sunroof has been brought to the forefront, and has attracted extensive attention and discussion from OEMs, parts companies and the media. In order to prevent passengers from being injured, it has become an inevitable trend for electric doors, windows and sunroofs to have anti-pinch functions. In order to ensure the safety of personnel, my country, North America, Europe, Japan and many other countries and regions have issued regulations and standards for the anti-pinch function of windows and sunroofs. [0003] At present, the existing window anti-pinch technology has the following...
