Navigation system with simplified display mode and display method thereof

Abstract

The invention discloses a navigation system with a simplified display mode and a display method thereof. The navigation system can improve the road driving safety and also has very high using convenience. The navigation system is provided with a normal operation mode and the simplified display mode. The navigation system comprises a processing module and a display module. When the navigation system is in the normal operation mode, the processing module generates a display content. The display content comprises a plurality of map resource layers and is used for displaying road information, while the display module displays the display content in a display picture. When the navigation system is in the simplified display mode, the processing module omits part of content ( such as part of map resource layers in the plurality of map resource layers) in the display content to generate a simplified display content, while the display module displays the simplified display content in the display picture.

Description

technical field [0001] The invention relates to a navigation system, in particular to a navigation system and a display method thereof which can omit part of display content in normal operation mode to produce simplified display content. Background technique [0002] A portable navigation device (PND) is a portable navigation system, which is generally used for both handheld and vehicle purposes, and provides rich and convenient navigation functions. The portable navigation device can retrieve relevant road information and point of interest (POI) information from the map database along with the positioning results, and display them on the screen for user reference, and can also plan an optimal route connection for use The starting point and end point set by the user, and indicate the direction and distance of the user to travel. figure 1 It is a common navigation display screen.

Problems solved by technology

figure 1 It is a common navigation display screen. As shown in the figure, there are many information displayed on the screen, such as the direction of travel, distance, speed, time, planned route, nearby alleys and points of interest, etc. However, the powerful function At the same time, the display screen of the portable navigation device has also become quite complicated. When the user cannot concentrate on identifying the information provided on the display screen while driving, an overly complex screen is not conducive to use.
