摘要
Abstract
Tire pressure monitoring system which is mainly used to monitor the tire pressure during driving in realtime has crucial significance for improving the safety of vehicles. Based on the hardware of tire pressure monitoring system,this paper describes the acquirement of wheel speed signals. How to reject the singular point has been researched. A method of attenuating wheel speed sensor errors by means of the resilient back propagation neural network has been presented. The corresponding neural network has been designed and the wheel speed correction has been realized. The results of simulation and experiment show that the method of eliminating wheel speed sensor error whose resolution is 2x10-4 rad, can remarkably decrease the error of sensor, and improve the resolution of wheel speed signals.关键词
