VEHICLE POSITIONING METHOD AND SYSTEM BASED ON MULTI-DATA FUSION, AND VEHICLE TERMINAL

A vehicle positioning method and system based on multi-data fusion, and a vehicle terminal. The method includes the following steps: calculating three vehicle body change angles through a wheel speed pulse signal, a steering wheel signal, and an inertial measurement unit; performing data fusion on the second vehicle body change angle and the third vehicle body change angle to obtain a fused change angle; performing, when data of the first vehicle body change angle is refreshed, filtering correction on the fused change angle through the first vehicle body change angle to obtain a filtering coefficient, and calculating a current vehicle body angle according to a vehicle body angle of a previous moment; and calculating a current vehicle body position of a vehicle according to a vehicle body position of the previous moment, the vehicle body angle of a current moment, and a vehicle driving distance.
