Abstract

The invention provides a vehicle-mounted navigation device, which comprises an input module, a current position detecting module, a memory, a micro controller and an output module, wherein the output module comprises a driver, projection equipment and a universal bracket; the input module is used for inputting commands and requests of a user to the vehicle-mounted navigation device; the current position detecting module is used for detecting the current position and the time of a vehicle; the memory is used for storing a digital map; the micro processor is used for calling the digital map in the memory to generate the road guiding according to the commands and requests inputted by the user and the current position of the vehicle, and outputting the generated result; and the output module is used for receiving road guiding information generated by the micro processor. The vehicle-mounted navigation device directly projects the road guiding information of the navigation system on front wind shield glass of the vehicle by utilizing the projection mode, thereby improving the driving safety of a driver; moreover, the invention also provides a navigation system utilizing the vehicle-mounted navigation device.

Description

technical field [0001] The invention relates to the field of car navigation, in particular to a car navigation device for car driving and a navigation system using the same. Background technique [0002] With the rapid development of electronic technology and digital information technology, more and more high-tech technologies are used in automobiles, and car navigation system is one of them. The car navigation system uses the advanced Global Positioning System (Global Positioning System, GPS) positioning technology, combined with the geographic information system (Geographic Information System, GIS) database provided by the vehicle navigation device and the traffic information network, so that the vehicle in motion has real-time automatic Positioning, navigation and other functions. [0003] Usually, the car navigation device is loaded on the car to determine the guiding route until the set destination, and guide the car to travel according to the determined guiding route,...
