The invention discloses a curve speed limit control method adaptive to road curvature. The curve speed limit control method comprises the following steps: step 1, carrying out self-learning based on vehicle speed and driver characteristic indexes to obtain a weight coefficient; 2, recognizing the curvature of the lane line based on a camera; and step 3, solving the optimal curve speed by adopting a dynamic planning method. The method has the advantages that the accuracy and the stability of vehicle curve driving can be improved, and according to the driving preference of a driver, the vehicle speed decision of curve driving in different degrees can be adaptively made according to different curve radiuses. Comprehensively optimizing the curve vehicle speed planning by considering the road curvature, the vehicle state, the driver characteristics and the like in a self-adaptive manner.
