Personalized dynamic real time navigation method and navigation system

Abstract

The invention provides a personalized dynamic real time navigation method, and relates to the GPS navigation field. The method comprises the following steps: a navigation terminal generates a path programming request and sends the path programming request to a navigation server; the navigation server generates an optimal path according to road network data, real time road condition information and user preference, and returns the optimal path to the navigation terminal; the navigation terminal periodically sends its own GPS position to the navigation server after navigation begins; and the navigation server sends a path update message to a corresponding terminal according to triggering conditions until navigation ends. The invention also provides a navigation system for realizing the personalized dynamic real time navigation method. The navigation system comprises the navigation terminal and the navigation server. The navigation method and the system thereof enable the navigation terminal to dynamically navigate according to the user preference and real time traffic information in order to guarantee that a vehicle runs according to the optimal path. The method and the system reduce the data traffic load, and time and energy consumed for data processing, so the method is feasible and is easy to popularize.

Description

technical field [0001] The invention relates to the field of GPS (Global Positioning System, global positioning system) navigation, in particular to a personalized dynamic real-time navigation method and a navigation system. Background technique [0002] With the development of the domestic navigation industry, the navigation technology has developed from static navigation to dynamic navigation, that is, dynamic path planning and navigation based on dynamic traffic information. Most of the current dynamic navigation methods put the calculation of the navigation path on the navigation terminal. In order to realize dynamic navigation, the navigation terminal needs to dynamically obtain real-time road condition information through data communication, and then judge whether it is necessary to re-calculate the route according to the road condition information. In this way, during a navigation process, the navigation terminal needs to perform a large amount of data communication ...

AI Technical Summary

Problems solved by technology

In terms of data traffic, data processing time consumption and energy consumption of navigation terminals, it is not conducive to the popularization of navigation methods

In addition, when calculating the route, the existing navigation method only avoids the congested road sections, which cannot guarantee the optimality of the route, and does not plan a personalized optimal route according to the user's driving preference, making the user experience poor
