Problems solved by technology

[0005] The purpose of the present invention is to overcome the defects of the existing vehicle navigation method and vehicle navigation system, and provide a new vehicle navigation method and vehicle navigation system. The navigation marks are directly marked on the image, which can solve the situation in the prior art that the driver chooses the wrong driving route because it takes a long time to understand the planar map or the three-dimensional map. It is very suitable for practical use.

Abstract

The invention relates to a vehicle navigation method and a vehicle navigation system. When the vehicle navigation system is navigating, a view image in front of a vehicle is determined to be displayed based on a fact that whether the distance between the current position of the vehicle and a crossroad in front of the vehicle is less than a critical length. If the distance between the current position of the vehicle and the crossroad in front of the vehicle is less than the critical length, the view image in the front is displayed by the navigation system, and a navigation mark is indicated on the front view image based on the map information used by the system and the navigation path determined by the information, thereby accurately guiding a driver to drive on the navigation path.

Description

technical field [0001] The present invention relates to a vehicle navigation method and a vehicle navigation system, in particular to a method for guiding 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 A vehicle navigation method and a 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 r...
