Embodiment Construction

[0019] Such as figure 1 Shown is a structural block diagram of the application platform of the vehicle navigation system of the present invention. The navigation system 11 communicates with the GPS system 12 installed on the vehicle, and the GPS terminal 12 communicates with the communication satellite 11 . The GPS system 12 can obtain the position signal of the vehicle in real time through the interaction with the communication satellite. The GPS system belongs to the prior art and will not be repeated here.

[0020] The navigation system 13 acquires positioning data from the GPS system 12, and provides real-time navigation information for the car according to the positioning data

[0021] Such as figure 2 As shown, the navigation system 13 includes a GPS receiving unit 21 , a yaw processing unit 22 , a human-computer interaction interface 23 , an electronic map 24 , and a path planning unit 25 .

[0022] The electronic map 24 can directly use the electronic map in the G...

Abstract

A vehicle navigation system comprises GPS receiving unit for receiving GPS positioning data, path planning unit for providing optimum path between two points based on electronic map stored in storage,yaw processing unit for judging whether vehicle is yawed from path planned by path planning unit or not according to received GPS positioning data and for sending command of replanning a path using current position as start point to path planning unit if it is. A navigation method is also disclosed.

Description

technical field [0001] The invention relates to a vehicle navigation system and method, in particular to a vehicle navigation system and method utilizing global positioning system data. Background technique [0002] With the development of the Global Positioning System (GPS), it is increasingly used for vehicle navigation. And similar navigation devices usually have the function of current position detection, that is, utilize the GPS system to determine the current position of the vehicle. A similar navigation device can also plan a route from the start point to the end point according to the start point and end point input by the user, and display the planned path on the display screen to guide the vehicle. Due to the reception blind area of ​​the GPS system or due to traffic congestion and other conditions, the vehicle often deviates from the predetermined route unintentionally or intentionally. If returning to the predetermined route again, it is often time-consuming an...
