Abstract

The invention discloses a vehicle navigation method and a vehicle navigation system. The navigation system determines whether the front visual field image of a vehicle is displayed according to a case that whether a distance from the present position of the vehicle to an intersection in front of the vehicle is less than a critical length during navigation. When the distance from the present position of the vehicle to the intersection is greater than the critical length, the navigation system displays the front visual field image, and marks a navigation marker according to used map information and a determined navigation path to accurately guide a driver to drive on the navigation path.

Description

technical field [0001] The present invention discloses a vehicle navigation method and a vehicle navigation system, especially a vehicle navigation that guides the driver of the vehicle to drive correctly on the navigation route indicated by the map information by marking the navigation mark on the front view image of the vehicle Method and vehicle navigation system. Background technique [0002] Generally, when a vehicle receives instructions from a navigation system to find a driving route while driving, the navigation route indicated by the navigation system will be displayed on a plane map or a three-dimensional map recorded by the navigation system, so that the driver of the vehicle can follow the plane map or the three-dimensional map. The adjacent road names or landmarks recorded on the three-dimensional map understand the navigation route indicated by the navigation system, and accordingly the vehicle is driven according to the navigation route in real time. When th...
