Embodiment Construction

[0012] Please refer to image 3 , image 3 It is a functional block diagram of a personal navigation device 200 in the present invention. The personal navigation device 200 includes a screen 12 , a GPS receiver 14 , a processor 16 , a user interface 18 , a memory 20 , and an electronic paper (E-paper) 22 . The GPS receiver 14 is used to receive a location signal, and the processor 16 can calculate the current coordinates of the personal navigation device 20 according to the location signal. The memory 20 stores a map database 32 and a route planning software 34 . After the user selects or inputs the information of the destination through the user interface 18, the processor 16 will execute the route planning software 34 to obtain all the information from the map database 32 according to the current coordinates of the personal navigation device 20 and the coordinates of the destination. Possible travel routes, and then the best travel route is displayed on the screen 12 to p...

Abstract

The invention discloses a personal navigation device for providing an electronic navigation map and a navigation method therefor. The personal navigation device comprises a housing, a screen and an electronic paper. The screen is installed on the housing and is used for displaying instructions for navigation from a starting point to a destination. The electronic paper is removably connected to the housing and is used for storing and displaying a detailed map showing an area which has a preset range and comprises a destination within the preset range.

Description

【Technical field】 [0001] The present invention relates to a personal navigation device and a related navigation method, in particular to a personal navigation device and a related navigation method that can provide mobile electronic maps. 【Background technique】 [0002] The Global Positioning System (GPS) is a medium-distance circular orbit satellite navigation system that can provide accurate positioning, speed measurement and high-precision time standards for most of the earth's surface (98%). A GPS-based personal navigation device is a well-known device widely used in the vehicle field, and its basic functions include providing a map database for displaying navigation instructions on the screen of the personal navigation device. In order to provide navigation information so that users can smoothly arrive at a destination from a starting point, the personal navigation device needs to have a positioning function, which can use an internal system (such as a GPS receiver) to ...
