METHOD FOR ACQUIRING ON-VEHICLE NAVIGATION INFORMATION AND ON-VEHICLE NAVIGATION SYSTEM

摘要

Disclosed in the present invention are a method for acquiring on-vehicle navigation information and an on-vehicle navigation system. The method comprises: acquiring information about a current target location to be reached by a vehicle, and planning a driving route for the vehicle (S302); acquiring key location information from the driving route, wherein the key location information comprises at least one of the following: one or more road sections on which the actual distance between neighboring at-grade intersections is less than a first preset distance, and one or more separated multi-level intersections (S304). According to the technical solution provided by the present invention, by analyzing road information in the driving route, the foundation is laid for a driver to expect to have a grasp of the road sections on which he is likely to go the wrong way while driving and pay attention accordingly.
