The invention discloses a moving vehicle positioning filtering and predicting method in a traffic light matching process. The method comprises the following steps of determining a fact that a vehicleoperation state is driving to a traffic light; acquiring current driving position positioning information of the vehicle and traffic light information in real time, and calculating distance between the moving vehicle and the traffic light; determining whether the distance gradually reduces, if yes, determining no positioning error, buffering a distance value and positioning information; if the distance suddenly increases and is higher than L, adding one to a continuous accumulation number-of-times CN, and entering a next step; and after a positioning error is determined, performing filtering and predicting, and correcting the distance value and the positioning data. According to the method, after the fact that the moving vehicle drives to the traffic light is determined, factors such as distance between the moving vehicle and the traffic light and moving vehicle turning around time are comprehensively considered so that correction is performed through a filtering and predicting algorithm when a positioning error of the positioning equipment occurs, thereby realizing high real-time performance. The moving vehicle positioning filtering and predicting method can be applied to an embedded system and can be easily applied to engineering practice.
