Design of Anti-pinch Window Lift Control Module

摘要

This paper puts forward a control scheme based on LIN bus for automotive anti-pinch power window. The article first gives an overview of the structure and function of the system, and then describes the design of the hardware and software in detail. We choose a 16-bit Free-scale chip MC9S12VR64 which has a mixed signal processing performance as the microcontroller. The anti-pinch algorithm is mainly based on the Hall signal, and the network communications use LIN bus. Finally, through trial and error to amend the anti-pinch algorithm, we get a satisfactory result.
