Description

A method of displaying vehicle speed based on satellite positioning data through a heads-up display and an electronic device thereof

The present invention relates to a method of displaying a vehicle speed based on satellite positioning data through a heads-up display and an electronic device thereof, and more particularly, to processing the vehicle position and speed using satellite positioning data received from a satellite. and to a method for displaying through a heads-up display and an electronic device thereof.

Recently, various systems have been developed that effectively transmit vehicle driving information and surrounding situation information to a driver. Among them, a head-up display (HUD) for a vehicle is used.

Such a head-up display displays driving information such as speed and location of the vehicle, navigation information, and vehicle status information on the windshield of the vehicle within a range that does not deviate from the driver's field of vision.

The initial head-up display was developed to provide flight information to the pilot when attached to an aircraft, and the vehicle head-up display was developed to apply this principle to a vehicle. In general, a method of providing information to a driver by reflecting a display output from a liquid crystal display through a windshield (windshield) or a combiner is applied to the head-up display.

Although such a head-up display may be provided in a state of being embedded mounted around the instrument panel of the vehicle, a vehicle equipped with a head-up display is often provided in an expensive vehicle or a vehicle equipped with a high-level option, so that the driver A separate head-up display terminal is often used by attaching it to a vehicle.

However, the liquid crystal display of the separately attached head-up display terminal has a problem in that the information projected on the windshield appears very faintly in the daytime due to the very low straightness of light.

This problem causes major problems such as making it difficult for the driver to intuitively check information output through the head-up display, and blurring the driver's concentration by dispersing the driver's field of vision.

In addition, most of the speed of the vehicle displayed through the head-up display of the vehicle is the speed confirmed through the vehicle driving record self-diagnostic device, and it is significantly different from the actual speed of the vehicle according to various variables such as vehicle settings and tire conditions. Therefore, the driver is learning the wrong sense of speed by driving based on the wrong speed by referring to this speed.

In addition, the departure of the speed enforcement zone may be determined by passing the location of the enforcement camera.

For example, the electronic device 100 may display the fixed camera icon 245 on the display when it is confirmed that the vehicle enters within 1 km in front of the fixed camera (or mobile camera) location. In addition, the static apparatus 100 may output information about the stationary camera and the speed limit by voice.

In addition, in displaying the distance from the reference position after the vehicle enters the speed enforcement zone, the electronic device 100 uses an indicator such as a plurality of points, bars, and blocks listed. The configured distance display area 651 may be displayed.

For example, referring to FIG. 6 , the distance display area 651 includes five (n) bars and states of these indicators (eg, ON, off, blinking, or strobe ( strobe)) to indicate the distance from the reference position when the vehicle enters the speed control zone.

When the distance of 1 km from the reference position is determined as the starting distance for the speed enforcement zone guidance according to the setting information of the electronic device 100 , one bar may mean a distance of 200 m. That is, one bar may be set to 20% (1/n) of the guide start distance.

For reference, assuming that the number of vehicle accidents is less in the second speed limit zone than in the first speed limit zone, the first guide start distance corresponding to the first speed limit zone is the second speed limit zone corresponding to the second speed limit zone. It may be set to be longer than the guide start distance. This is because it is necessary to start guidance in advance as the number of times of vehicle accidents increases, the more dangerous the area becomes.

When the vehicle continues to approach the stationary camera and is located at a distance of 200 m from the stationary camera, the electronic device 100 may turn off the second bar of the distance display area 651 .

When the vehicle continues to approach the stationary camera and is located at a distance of less than 200 m from the stationary camera, the electronic device 100 may display the first bar of the distance display area 651 in a blinking state.

When the vehicle continues to approach the stationary camera and arrives at the position of the stationary camera, the electronic device 100 may turn off bar 1 of the distance display area 651 and determine that the vehicle has left the speed limit zone.
