In order to achieve the safety and rapid response requirements of the electric windows, the electric window anti-trap system based on LIN bus using signal detection technology is designed. The real time positions of the windows are detected by the Holzer sensor, and the system uses the changes in current of the DC motor to deter- mine the obstacle with the Freescale's MM912F634 as the controller. The platform is connected by a LIN btls. The experimental results show that the system can effectively detect the obstacle, and respond quickly to the anti-trap. The system is stable, reliable, fast in operation and low in cost. It also has strong anti-interference ability and great potential on the market.
