Description

How to display the screen of the vehicle traffic guidance system

The present invention relates to a method of displaying a screen of a vehicle traffic guidance system that reads map data stored in an internal memory and displays it on a monitor while receiving radio wave information corresponding to a vehicle's current position from a satellite. When displaying the map to the desired destination on the screen, the driver can selectively display the colors of the road, buildings, rivers, etc. and the background color of the map displayed on the screen according to the surrounding environment of the screen. The present invention relates to a screen display method of a traffic guide system for a vehicle to improve visibility while selecting arbitrarily.

Nowadays, the increasing number of vehicles has driven many people to drive to their destinations, and the complexity of road conditions and the increasing number of vehicles has led to a lot of traffic coming from behind if they do not drive quickly and accurately to their destination. It hindered the progress of the vehicles.

In the case of a first-time or busy city, if the driver does not know the exact route to his destination, the embarrassed driver may not be able to operate the vehicle smoothly and delays in finding the destination.

Therefore, it is necessary to ask a passing pedestrian for directions or look at the route to the destination where the map is intended to go, but there is a problem in that it causes inconvenience to the driver, as well as damages other vehicles following from behind during the delayed time.

Therefore, the data of each map is subdivided and input using CD-ROM (Compact Disk-Read Only Memory) for navigation system for vehicle traffic guidance, and then GPS (Global Positioning System) receiver, gyro sensor, Geomagnetic sensors and vehicle speed sensors are used to match the current vehicle's location with map data and to display it on a monitor installed inside the vehicle for easy road search and route selection.

However, the vehicle navigation system as described above in the vehicle CD-ROM driver, CD-ROM map program, GPS receiver. By using hardware such as gyro sensor, geomagnetic sensor, vehicle speed sensor, etc., the map of longitude and latitude is converted into a flat map and displayed on the display screen, displaying the current location mark and destination mark of the vehicle and responding to the movement of the vehicle. Since the display was to be able to check the color of the screen according to the surrounding environment, there was a disadvantage that visibility is poor.

Therefore, in the related art, a first color code storage means for storing various color codes and a second color code storage means having at least one of the combination of the color codes and the color code having a different combination are different according to the driver's choice. The display was made by sum of colors.

However, according to the screen display method of the conventional vehicle traffic guidance system as described above, even if the color of one part is difficult to see on the current screen, the total color tones must be changed to another color tones. There was a problem that occurs when the visibility is not improved.

Accordingly, in the present invention, when the driver driving the vehicle selects the display mode of the map and looks at the screen and the visibility is reduced by the surrounding environment, the driver arbitrarily outputs the color stored in the color storage means. It is an object of the present invention to provide a screen display method of a traffic guidance system for a vehicle that allows a driver to see the screen visibly by automatically outputting a color that is not currently displayed if there is no selection.

In order to achieve the above object, the present invention enables a microprocessor to recognize traffic information in consideration of a driving direction of a vehicle in a general vehicle traffic guide system so as to guide the image and voice,

Selecting an arbitrary color by the color selection key and storing by the color storage key;

When the driver selects the display mode of the map through the selection key of the key input unit, the microprocessor displays the starting position and the destination position of the vehicle through the display unit and the driver inputs the place name of the starting point and the destination through the up / down keys and the input key. To make it work,
