Problems solved by technology

[0003] Since the navigation process is carried out along with the driving of the vehicle, correspondingly, not only the vehicle mark indicating the current position of the vehicle will move on the position of the electronic map, but also the displayed electronic map will also move as the vehicle advances. However, in the prior art , the movement of the car logo with the current position of the vehicle is not synchronized with the movement of the electronic map with the progress of the vehicle. It often appears that the car logo is located at the corner of the display screen of the navigation device. Location

Embodiment Construction

[0022] Such as figure 1 As shown, an embodiment of the present invention provides a navigation display method, including:

[0023] 11. Determine the user's current location and the current scale used to display the map.

[0024] 12. According to the current map display mode and the current map display mode, determine the preset display position of the car logo used to identify the user's current position on the display screen.

[0025] 13. According to the preset display position of the car logo, the current position of the user, and the current scale used to display the map, the map data to be displayed is obtained from the map database and displayed.

[0026] The execution subject of the navigation display method in the embodiment of the present invention may be a navigation system or a navigation device.

[0027] It can be seen from the technical solutions provided above that during the navigation process, regardless of the movement of the current position of the vehicle and the move...

Abstract

The embodiment of the invention relates to navigation display method and device, wherein the navigation display method comprises the following steps of: determining the current position of a user and a current measuring scale for displaying a map; determining the preset display position of a car mark for identifying the current position of the user on a display screen according to the current map display mode and the current map display way; and acquiring and displaying map data to be displayed from a map database according to the preset display position of the car mark, the current position of the user and the current measuring scale for displaying the map. In the navigation process, no matter whether the current position of a vehicle is moved and the displayed electronic map is moved or not, the navigation display method and device can ensure that the car mark for identifying the current position of the user is displayed in the preset position of the display screen all the time to prevent the car mark from positioning in the corner of the display screen, thereby being convenient for the user to visually determine the current position of the user on the display screen.

Description

Technical field [0001] The invention belongs to the technical field of navigation, and particularly relates to a navigation display method and device. Background technique [0002] At present, the vehicle-mounted Global Positioning System (GPS) has been widely used in daily work and life. The user can set the starting point, destination, place to pass, avoiding place, etc. in the navigation device. The navigation device plans an appropriate route according to the user's setting and displays it for the user's reference. During the navigation process, the electronic map and the current location of the user are displayed on the display screen of the navigation device, and the current location of the user is generally displayed with a car logo. [0003] Since the navigation process is carried out with the driving of the vehicle, correspondingly, not only the car mark indicating the current position of the vehicle will move on the position of the electronic map, but also the displayed ...
