Abstract: This paper is concerned with the control mechanism design for automotive power windows system to enhance safety and comfort for the driver and the passenger. A new low-cost anti-pinch system has been presented for exceeding FMVSS118-S5 safety standards. First, the Hall effect IC as a speed sensor is specifically installed on the motor rotor for the anti-pinch system. Next, the effects of the number of Hall sensors and angular position of each sensor on the anti-pinch performance have been investigated to obtain optimal speed resolution. Then, three Hall IC sensors have been employed to a new anti-pinch system. In addition, it is found that the optimal sensor position is 60° through extensive experimental tests. Finally, the new motorised window system has been verified to exceed the rigorous international regulations while guaranteeing safety and comfort.
