摘要

This paper describes a study on the improvement of positioning accuracy for car navigationrnsystems, which will realize so-called door-to-door navigation. In today's car navigationrnsystems, directions of a vehicle detected by a yaw-rate gyroscope sensor sometimesrndeteriorate as the vehicle body inclines, which result in serious positioning errors.rnWe have developed an algorithm which compensates the output of a yaw-rate gyroscopernsensor using estimated pitch and roll angles of a vehicle. Experimental results show thernproposed algorithm has improved the positioning error over 50 percent.
