Simulation analysis of electric window anti-pinch based on speed difference method

Abstract

: With the continuous development of the automobile industry and people's increasing emphasis on automobile safety, anti-trapping of electric windows as an important safety function has attracted more and more attention from users. This paper studies the speed difference-ripple scheme of electric window anti-pinch, analyzes the theory of speed difference method, and expounds the principle and application of ripple technology. Simulink software is used to model and simulate the current and speed difference, which verifies the feasibility and effectiveness of the scheme. The research results show that the speed differential method-ripple scheme is a feasible and effective anti-pinch technology for electric windows, and it has broad application prospects compared with the traditional Hall sensor anti-pinch technology.
