The invention provides a method, a system and a device for generating auxiliary lane changing information by a high-precision map. The method comprises the following steps: S1, acquiring lane data of lane change in a high-precision map; s2, reconstructing a lane topology according to lane characteristics in a lane changing interval, and generating a new lane center line link; s3, completing the generation of a lane changing point and the curve optimization of a lane changing lane according to the newly generated lane center line link; and S4, outputting a new high-precision map, and refreshing the generated lane center line and lane changing point into the high-precision map. A clear lane change mark is provided, and the lane center line of a road change section is optimized, so that a lane guiding effect can be provided; lane change reminding and lane change guiding are achieved, lane change of a compact line of a lane is avoided, the driving experience is improved, and support and adaptation of a high-precision map to the lane change function of automatic driving are improved. The performance of the lane changing function in automatic driving is improved, and the automatic driving process is accelerated to a certain extent.
