The invention relates to the technical field of intelligent driving, in particular to a speed limit control and crossroad steering recognition method and system fusing multiple features, and the method comprises the following steps: S1, obtaining the current speed of a vehicle, adaptively calculating the preview distance in front of the vehicle based on a speed time chart, obtaining the preview distance, and obtaining a section of map points in front of the position of the vehicle; the method does not need to depend on high-precision map labeling, manual labeling workload and cost are reduced, curvature speed limiting refers to adjusting the vehicle speed according to the road curvature so as to ensure safe driving, the system calculates and updates the curvature information of the road in real time through multi-sensor fusion, and therefore the accuracy and real-time performance of speed limiting control are improved, and the driving safety is improved. The multi-feature fusion means that the system not only depends on a single sensor, but comprehensively utilizes various data sources to reduce the influence of environmental change on speed limit calculation, so that the driving safety is improved.
