Abstract

This invention refers to the navigation technology, aiming to defect existed in the current technology that the vehicle speed cannot be pre-adjusted because the state of the crossing traffic indicating lamp to be arrived cannot be pre-acquired. This invention provides a navigation device, comprising: a display device for displaying the navigation path; a crossing state indicating module that has a communication connection with the display device and is used for determining the crossing state of the crossing to be arrived on the navigation path, and controlling the display device to display the corresponding indicating information. This invention further provides a navigation method. The crossing state of the cross to be arrived can be predetermined and pre-displayed by depending on the state periodic table of the traffic indicating lamp, thereby determining the current state of the crossing traffic indicating lamp and the rest keeping time thereof, such that the user can pr-adjust the vehicle speed to adapt to the traffic indicating lamp state of the crossing to be arrived.

Description

technical field [0001] The present invention relates to navigation technology, more specifically, to a navigation device and a navigation method thereof. Background technique [0002] Vehicle navigation technology is an important branch of GPS (Global Positioning System, GPS) technology. The working principle of the vehicle navigation system based on this technology is that the vehicle navigation terminal receives the position coordinates transmitted by at least 3 satellites among the 24 GPS satellites around the earth, and compares them with the position coordinates recorded in the electronic map stored in the terminal itself. Matching, in order to determine the exact position of the navigation object equipped with the terminal in the electronic map. [0003] In a specific application process, the car navigation device can quickly calculate the best route according to the origin and destination information input by the user, and display it on the display device configured ...
