Navigation remaining time acquiring method and navigation remaining time acquiring apparatus

Abstract

The present invention belongs to the field of navigation, and provides a navigation remaining time acquiring method and a navigation remaining time acquiring apparatus. The navigation remaining time acquiring method comprises: receiving a navigation remaining time acquiring request; according to the current position and the end point position of a vehicle, determining a navigation remaining route of the vehicle; acquiring real-time vehicle speed information of the navigation remaining route; and according to the real-time vehicle speed information, calculating the navigation remaining time corresponding to the navigation remaining route. According to the embodiments of the present invention, the navigation remaining time is calculated according to the real-time vehicle speed information of the navigation route, such that the accuracy of the acquired navigation remaining time is high.

Description

technical field

[0001] The invention belongs to the field of navigation, in particular to a method and device for acquiring navigation remaining time. Background technique

[0002] When the vehicle uses the navigation system for navigation and positioning, in order to enable the user to better plan the travel time, the time required for the route between the current position of the vehicle and the destination is often calculated in the planned route. By calculating the time values ​​corresponding to different routes, the driver can be provided with more route selection information and the travel time can be effectively reduced.

[0003] The existing vehicle travel time generally uses the following two calculation methods:

[0004] 1. Obtain the current driving speed of the vehicle or the average driving speed of the vehicle in the recent period, and obtain the navigation time through the navigation distance and driving speed;

[0005] 2. Obtain road grade and road speed li...
