A vehicle-based road condition information forecasting system and method

Abstract

The invention provides a vehicle-based road condition information forecasting system and method. Corresponding decision information, including road condition information, road use information, meteorological disaster information, various auxiliary driving information and the like, can be intelligently provided for a driver according to factors such as the degree of the familiarity of the driver with surrounding information, environment change factors, vehicle traveling tracks and expected destination routes. The system and method are different from the prior art in that one route is recommended according to starting point and destination information set by the user and is not changed any more. According to the vehicle-based road condition information forecasting system and method providedby the technical schemes of the invention, the driver can automatically receive updated decision information in an advancing process, the decision information is actively pushed without intervention of the driver, and therefore, safety is guaranteed while driving efficiency is improved to the greatest extent; and various possible factors including an actual road condition in actual data acquisition, an inferred road condition based on actually acquired data, and a predicted road condition based on the inferred road condition and the like are considered.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a vehicle-based road condition information forecasting system and method. Background technique [0002] At present, drivers often receive road condition information when driving on the road, and make predictions about the road ahead based on the road condition information, and plan the road itinerary. Road condition is a technology proposed for today's urban traffic congestion. It can reflect the traffic conditions in the area in real time, guide the best and fastest driving route, and improve the efficiency of road and vehicle use. [0003] With the rapid development of the automobile industry, more and more in-vehicle devices have been developed, such as in-vehicle navigation system, GPS (Global Positioning System) positioning, TTS (Text to Speech) broadcast, in-vehicle DVD player, in-vehicle communication, etc. At present, the application of locating the cur...

AI Technical Summary

Problems solved by technology

However, the system needs to judge and prompt common routes when the navigation is turned on after the vehicle is turned on for route planning and search.

It is impossible to obtain the vehicle route information before the car is started, it takes time to wait, and at the same time it needs to think about the operation, the navigation is not smart enough and convenient

In the Chinese patent document with the publication number CN101571401A, a navigation system is disclosed, which takes into account the traffic restriction factors of the road when planning the navigation path, but does not consider actively forecasting road condition information to the user, and further traffic congestion in the area. Path avoidance; the degree of fit with the actual traffic and vehicle conditions is not high enough, and it is not humanized enough

[0005] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
