Embodiment 1

[0028] figure 1 The implementation flow of the method for obtaining the remaining navigation time provided by the first embodiment of the present invention is shown, and the details are as follows:

[0029] In step S101, a request for acquiring the remaining navigation time is received, and the remaining navigation route of the vehicle is determined according to the current location and the destination location of the vehicle.

[0030] Specifically, the request for obtaining the remaining navigation time may be sent when the vehicle starts to navigate, or periodically during the navigation process. Send a navigation remaining time acquisition request when starting navigation, for requesting to obtain the driving time required for the entire navigation remaining route; periodically send a navigation remaining time acquisition request during the navigation process, for navigating the remaining navigation time according to the sending cycle The driving time required for the rema...

Embodiment 2

[0048] figure 2 The implementation flow of the method for obtaining the remaining navigation time provided by the second embodiment of the present invention is shown, and the details are as follows:

[0049] In step S201, a request for obtaining the remaining navigation time is received, and the remaining navigation route of the vehicle is determined according to the current location and the destination location of the vehicle.

[0050] In step S202, the first time point is obtained, the first time point is the time point when the request for obtaining the remaining navigation time is received, and the remaining navigation route is divided into N road sections according to the driving speed, and the N is a positive integer greater than 0.

[0051] Wherein, the remaining route of the navigation is divided into N road sections according to the driving speed, and the driving speed can be the driving speed of historical statistics, can be divided by different road section names,...

Embodiment 3

[0067] image 3 The implementation process provided by the third embodiment of the present invention is shown, and the details are as follows:

[0068] In step S301, a request for obtaining the remaining navigation time is received, and the remaining navigation route of the vehicle is determined according to the current location and the destination location of the vehicle.

[0069] In step S302, a first time point is obtained, the first time point corresponds to the time point when the navigation remaining time acquisition request is received, and the navigation remaining route is divided into N road sections according to the driving speed, and the N is a positive integer greater than 0.

[0070] In step S303, according to the time point when the vehicle arrives at the i-th road segment, the vehicle speed corresponding to the time point when the vehicle arrives at the i-th road segment is obtained. , the driving speed corresponding to the i-1th road section before this road ...

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...
