Problems solved by technology

[0003] When implementing the above technical solution, the inventors found at least the following problems in the prior art: in the prior art, if the information triggering position is too far away from the graphic representative position, the terminal will display the graphic real-time traffic information prematurely, which is harmful to the user Driving has an impact; if the information trigger position is too close to the graphical representative position, the terminal will display graphical real-time traffic information too late, resulting in insufficient time for the user to make a decision
In the above two cases, the terminal cannot provide high-quality graphical real-time traffic information display function, which makes the user experience poor

Embodiment 1

[0022] The embodiment of the present invention provides a method for information trigger position selection, such as figure 1 As shown, the method includes the following steps:

[0023] 101. Select an estimated information trigger position.

[0024] 102. According to the estimated information trigger distance between the estimated information trigger position and the graphic representative position, and the historical time record value of the estimated information trigger distance, acquire the estimated information trigger position to the graphic representative position reference speed.

[0025] The triggering position of the estimated information is described relative to the representative position of the graphic, and the representative position of the graphic is the first divergent intersection depicted by the graphical real-time traffic information. The distance between the graphic representative position and the estimated information triggering position is the estimated ...

Embodiment 2

[0031] The embodiment of the present invention provides a method for information trigger position selection, such as figure 2 As shown, the method includes the following steps:

[0032] 201. Select an estimated information trigger position according to a preset selection rule.

[0033] 202. According to the estimated information trigger distance between the estimated information trigger position and the graphic representative position, and the historical time record value of the estimated information trigger distance, acquire the estimated information trigger position to the graphic representative position reference speed.

[0034] The triggering position of the estimated information is described relative to the representative position of the graphic, and the representative position of the graphic is the first divergent intersection depicted by the graphical real-time traffic information. The distance between the graphic representative position and the estimated information...

Embodiment 3

[0054] An embodiment of the present invention provides a device for information trigger location selection, such as image 3 As shown, the device includes: an estimated information trigger position selection unit 31 , a reference speed acquisition unit 32 , and an actual information trigger position selection unit 33 .

[0055] The estimated information trigger position selection unit 31 is used for selecting the estimated information trigger position.

[0056] The reference speed acquisition unit 32 is used to obtain the estimated information trigger position to The graph represents the reference velocity of the position.

[0057] The triggering position of the estimated information is described relative to the representative position of the graphic, and the representative position of the graphic is the first divergent intersection depicted by the graphical real-time traffic information. The distance between the graphic representative position and the estimated information ...

Abstract

The embodiment of the invention provides a method and a device for selecting an information trigger position, relates to the field of intelligent traffic information service, and can display graphical real-time traffic information on a terminal in appropriate time. The method comprises the following steps of: by using a pre-estimation information trigger distance which is set and a recording value of historical time in which a vehicle runs for the pre-estimation information trigger distance, acquiring a reference speed at which the vehicle runs from a pre-estimation information trigger position to a graph representation position, and thus obtaining an appropriate practical information trigger distance by multiplying pre-set reference time by the reference speed; and determining an appropriate practical information trigger position. The embodiment of the invention is applicable to displaying of the graphical real-time traffic information.

Description

technical field [0001] The invention relates to the field of intelligent traffic information services, in particular to a method and device for selecting an information trigger position. Background technique [0002] With the continuous improvement of intelligent transportation technology, more and more users start to use various terminals, such as navigator terminals (GPS, Global Positioning System), mobile phone terminals, etc., to obtain real-time graphical traffic information. Take the navigator terminal as an example. On the navigator terminal, the map, as well as the current position of the vehicle, driving speed, route prompts, intersection steering and other driving information will be displayed. When the vehicle drives to the information trigger position, the navigator terminal can automatically send a request to the server, and after receiving the information returned by the server, it will display the graphical real-time traffic information of the graphical repres...
