The invention discloses a shunting automatic driving fusion positioning technology, and belongs to the field of railway traffic management. In order to solve the problem that the positioning accuracy is reduced in a shunting scene with more turnouts, the positioning error is minimized by fusing an accelerometer, a speed sensor, a GNSS receiver, an interlocking system, a query host and other sensors and integrating an electronic map, station track relative offset position information and other modes, and the positioning accuracy is improved. And through interaction with a ground control center, a shunting operation list and cache position information are obtained, train joint positioning is participated, and the position information of the parking train is obtained in real time. The method is used in a railway signal and control system, and has the advantages of high precision and high reliability.
