Electric Window Regulator Based on Intelligent Control

         

摘要

In order to effectively solve the problem of installation cost of automobile electric windows and the safety of passengers,the window regulator of the car must have an intelligent control function.For example,most automobile windows now have an anti-pinch function.In this paper,the model of dc brushed motor is analyzed,an intelligent control scheme for automotive power windows is proposed,and the relationship between current ripple and window travel,motor current,and extemal resistance are verified.In the hardware design,S9S 12G128 is the main control chip,and the motor current acquisition method is designed.In the software design,intelligent control methods such as current integration method,adaptive and self-learning algorithm,and intelligent speed regulation method are proposed to realize functions such as automatic w indow opening and closing,intelligent anti-pinch,and intelligent speed regulation.After many experiments,the results prove the feasibility of the above methods and the stability of the system.
