Research On Anti-Pinch Algorithm And System For Electrical Window

Modern automotive technology is the microcosm of the development of human technology and civilization. With the rapid development of automotive electronic technology, the technology of automotive electronics has made a remarkable development. However, the domestic research begins very late, and the gap between the domestic and foreign countries is so large. Consequently, many technology gaps are to be filled. This author carries out the research on the force of the technology of anti-pinch algorithm and system for electrical window in the context of the development.In this paper, the author gives a summary on the development on the controlling technology of anti-pinch system for electrical window, points out that the emphasizes are high reliability, low cost, integration and the ability of the resistance to the change of environment, and determines to have research on the anti-pinch algorithm and system for electrical window.The author gives the parameter of calculation and the model of the window lift system. After comparing the other three methods, the author points out the definition of the anti-pinch region and force. In this paper, matlab simulation which is based on the given model focuses on the relationship among the algorithm, anti-pinch region, road conditions and the mistaken pinch. The results show that matlab simulation is useful for the analysis and calculation of the anti-pinch system. In addition, the author also describe the anti-pinch strategies of the complex environment, and designs the hardware and software. The design criteria of hardware are integration, miniaturization, and low cost. The goals of the software design are personalized, high safety, and reliability.Under the context of the overall controlling optimization of the automotive electronic, anti-pinch system for electrical window will be more secure and reliable, and the anti-pinch technology on electrical window will develop much more rapidly. The research of this paper is a trial of the anti-pinch technology for electrical window. It is expected that the work and results will do some help for the research in relevant field.
