Disclosed are a road feature point extraction method and system. The road feature point extraction method comprises: acquiring map information for the current position of a vehicle (S110), wherein the map information comprises the attributes of the current road and the attributes of the next road section; comparing the attributes of the current road with the attributes of the next road section to determine the road type of the next road section (S120); and extracting, in conjunction with the road type of the next road section and the map information corresponding to the next road section, a road feature point representing a road scene on the next road section, and outputting the name of the extracted road feature point and information of the relative distance between the road feature point and the vehicle (S130). By determining a road feature point capable of precisely representing a road scene and extracting the name and position information of an important road feature point relating to vehicle control, without the need for separately collecting overall road information in the vicinity of the current position of a vehicle, the vehicle can be precisely controlled.
