Embodiment Construction

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0040] In the existing real-time road condition navigation route updating and displaying method, the navigation server periodically sends the updated navigation route to the mobile terminal. Although the updated navigation route is the current optimal route, if the entire route is considered, the updated navigation route is the optimal route, but ...

Abstract

The invention provides a method for updating and displaying a navigation route of a real-time traffic status and a navigation server. The method comprises the following steps of: calculating the running distance of a mobile terminal which runs for a first preset period of time according to an acquired current optimal route; calculating a second period of time needed by the mobile terminal for running by the running distance according to the acquired current displayed route; and when the difference between the second period of time and the first preset period of time is more than a preset threshold, transmitting the current optimal route to the mobile terminal to update a current displayed route into a current optimal route by using the mobile terminal. Due to the adoption of the method for updating and displaying the navigation route of the real-time traffic status and the navigation server, the displayed navigation route is updated only when the current optimal route is remarkably superior to the current displayed route, the updating frequency of the navigation route is lowered, and valuable communication resource is saved.

Description

technical field [0001] Embodiments of the present invention relate to intelligent transport system (Intelligent Transport System, ITS for short) navigation technology, in particular to a real-time road condition navigation route update display method and a navigation server. Background technique [0002] The intelligent transportation system realizes the harmonious and close cooperation of people, vehicles and roads by dispatching vehicles, thereby improving transportation efficiency, alleviating traffic congestion, improving road network passing capacity, reducing traffic accidents, reducing energy consumption, and reducing environmental pollution. Pollution. Specifically, in an intelligent transportation system, navigation technology can be used to dispatch vehicles. Set up a mobile terminal for navigation on the vehicle, and the navigation server plans according to the starting point and destination of the user using the mobile terminal, obtains the navigation route and ...
