Description
The present invention relates to a vehicle traveling direction display method and apparatus.
A head-up display (HUD) for a vehicle displays various driving information such as vehicle speed, RPM, navigation information (for example, a map, information on the progress of a vehicle, etc.) on the front window of a vehicle, It is a device to help safe driving by helping the driver to keep the front view without turning his head to check the information while driving the vehicle.
Generally, in order to check the speed of a vehicle while driving, it is necessary to look at the speedometer of the instrument panel by tilting the head so that the driver's view is moved from the front of the vehicle to the instrument panel for a short period of time. However, when the driver uses the head-up display (HUD), he can check the necessary information without having to bow his head.
Korean Patent Registration No. 10-0813492 (Mar. 07, 2008) discloses a light source for generating illumination light; A video source having a micro display panel for receiving various video information required by a driver and outputting an image signal; An optical system having a filter for converting an image output from an image source through the illumination light into a stereoscopic image; A mirror system for outputting a stereoscopic image output from the optical system in a windshield glass direction; And a combiner for reflecting the stereoscopic image output from the mirror system in a direction of the driver. The head-up display device of the present invention can realize compact or slim-like three-dimensional image information.
FIG. 1 shows an embodiment in which a conventional navigation device displays navigation information, and FIG. 2 shows an example of a traveling direction of the vehicle in a conventional head-up display.
Referring to FIG. 1, the navigation device also displays information about the vehicle traveling direction and information about the complex road of the vehicle. In this way, when the vehicle makes a right turn in front of a certain distance (for example, about 100M) in a complex area having a plurality of lengths, the conventional hair-up display merely displays a right turn direction as shown in FIG. In this case, the driver can not find the correct road.
This is because the screen displaying the data on the front windshield of the vehicle by outputting the navigation information in the conventional head-up display is as small as about 5 inches, so that only the rotation information is simply expressed by using the predetermined icon only the traveling direction of the vehicle It is because.
In addition, since the route guidance information used by the conventional head-up display is expressed by simplifying the direction information into several direction icons, accurate road guidance information can not be transmitted to the driver in the road environment as shown in FIG. In addition, the conventional head-up display has a problem that it is difficult to precisely confirm the road in a situation where the driver's view is not secured, such as nighttime or mist.
