Embodiment 1

[0017] An embodiment of the present invention provides a traffic information prompt method, such as figure 1 As shown, the method includes the following steps:

[0018] Step 1, the navigation device determines the current navigation route. The current navigation path is a navigation path used during current navigation. The navigation path may be a navigation path planned by the navigation device, or may be multiple navigation paths planned by the navigation device according to different planning principles (such as system recommendation, high-speed priority, least charge, shortest time, or shortest distance, etc.), The user selects one of the multiple navigation paths as the current navigation path, or it can be a planned and available navigation path transmitted by other devices;

[0019] Specifically, the navigation route planned by the navigation device may be planned to obtain the navigation route according to the destination and the departure place, and the departure pl...

Abstract

The invention discloses a traffic information issuing method and a navigation device and belongs to the field of location-based service. The method comprises determining a current navigation path; according to the navigation path, determining traffic information to be downloaded; downloading the determined traffic information and issuing the traffic information. The invention also discloses a navigation device for implementing the traffic information issuing method. According to the traffic information issuing method, by determining the traffic information to be downloaded according to the navigation path, the downloaded traffic information can be associated with the navigation path, and the downloaded traffic information can be issued. Compared with a mode of downloading the traffic information of a whole map interface every time, the traffic information issuing method can save the downloading time and the downloading traffic, achieve pointed traffic information issuing and provide users with more pointed effective information.

Description

technical field [0001] The invention relates to the field of location services, in particular to a traffic information prompting method and a navigation device. Background technique [0002] A navigation device refers to a device with location service functions and related functions. Its working principle is that the navigation device determines the location coordinates of a specific location, and matches them with the location coordinates recorded in the electronic map stored by itself, so as to determine the location of the vehicle equipped with the device. The accurate position of the navigation object of the navigation device in the electronic map. The navigation device can be a vehicle terminal, a portable navigator, a mobile phone terminal, and the like. Navigation objects can be vehicles, pedestrians, etc. After the user sets the starting point and the destination, the navigation device will plan a navigation path, and navigate for the user according to the planned ...
