The invention provides an automatic driving vector line curvature fitting method and device, electronic equipment and a medium, and relates to the technical field of electronic maps, and the method comprises the steps: obtaining a distance value of a target road section and a corresponding curvature original value; sorting the path value and the curvature original value according to a sequence from small to large to obtain a path number and a curvature sequence number; determining the curvature original value corresponding to the point of which the curvature serial number is the preset threshold value as a curvature target value; cyclically traversing the curvature original value based on the curvature target value to obtain an upper curvature target value and a lower curvature target value of each point of the arc line segment or the straight line segment in the target road segment; and determining the average value of the curvature upper target plate value and the curvature lower target plate value as the c
