Navigation system for vehicles and its method

Abstract

The invention provides a vehicle navigation system and method. The vehicle navigation system includes a signal receiving module capable of electrically connected with each other for obtaining the first position information of vehicle, a position selected module for obtaining the second position information of the vehicle, a route programming module for obtaining the predetermined progress route according to the first and the second position information, an image obtaining module for obtaining at least one road condition image information related with the predetermined progress route according to the predetermined progress route, a display module for displaying at least road condition image information, and a route selected module for selecting for keeping the former determined progress route or response to the route programming module to obtain the new predetermined progress route.

Description

technical field [0001] The present invention relates to a vehicle navigation system and method, in particular to a vehicle navigation system and method capable of displaying road condition image information related to a vehicle's predetermined travel path. Background technique [0002] Generally speaking, when the driver is driving the vehicle, if he can know the road conditions (such as traffic volume, congestion level, whether there is a traffic accident or whether it is under construction, etc.) on a bad path. In addition to saving driving time, it can also ensure driving safety. [0003] However, the vehicle navigation system in the known technology can only provide navigation guidance according to the planned predetermined route, and cannot let the driver know the road conditions on the planned predetermined route in advance. Therefore, the driver may drive on a path with poor road conditions according to the planned predetermined path. Although the known technology ...

[0003] However, the vehicle navigation system of the known technology can only provide navigation guidance according to the planned predetermined route, and cannot let the driver know the road conditions on the planned predetermined route in advance.

Therefore, the driver may drive on a path with poor road conditions according to the planned predetermined path

Although the known technology can allow the driver to listen to the road condition report by the radio, the broadcast method can only be used for comprehensive and large-scale road condition reports, and cannot provide individualized and individualized road conditions for each driver. really limited

Moreover, the road condition reporter and each driver have different subjective opinions on whether the road condition of the same route is good or not. Therefore, if the driver simply listens to the road condition report, he may still not be able to correctly judge whether to maintain the original driving route or change the road.

Furthermore, the broadcasting method usually cannot be dynamically updated in real time, so the road condition report listened to by the driver is likely to be in error with the current actual situation, causing the driver to make a wrong judgment
