Description

Head-up displaying device for preventing lane departure}

The present invention relates to a head-up display device for preventing lane departure, and more particularly, by being configured to display a lane image on the windshield of the vehicle, which is the driver's visible area, to prevent the driver from departing from the lane and to ensure safe driving of the driver. It relates to a head-up display device for preventing lane departure, which can induce not only induction, but also can increase convenience and efficiency of use by simple installation and operation, and reduce cost by having a simple structure and design.

In recent years, as roads have been expanded and the vehicle penetration rate has increased exponentially, the incidence of traffic accidents has also rapidly increased.

In particular, in the case of a novice driver who is inexperienced in driving, as the phenomenon of departure from a lane while driving occurs uncommonly, various devices and systems for preventing lane departure of a vehicle are being studied.

On the other hand, as various sensing and shooting technologies are advanced, various vehicle information is displayed as virtual images on the windshield, which is the front glass window of the driver's seat, so that the driver can check vehicle information while continuously looking ahead while driving the vehicle. A display (HUD, Head-Up Display) system has been developed and is being mounted on a vehicle.

In general, a conventional head-up display (HUD) system includes a collection means for collecting information related to driving of a vehicle made up of various sensors and cameras, and meaningful information necessary for a driver by analyzing and utilizing the data collected by the collection means. It consists of a control unit for generating in-vehicle information, and irradiation means for displaying the vehicle information generated by the control unit on a vehicle windshield.

However, the conventional head-up display (HUD) has disadvantages in that various sensors and cameras are installed on the vehicle body, so installation and operation are complicated and cost is burdened.

In particular, assuming that the conventional head-up display system displays a virtual lane image, the conventional head-up display system not only needs to install collection means for collecting the location information of the actual lane, but also analyzes the collected data.

In particular, assuming that the conventional head-up display system displays a virtual lane image, in the conventional head-up display system, the collection means for detecting the location information of the actual lane must be installed in the vehicle body, and at the same time, the collection means As the calculation process of analyzing the collected data and detecting the location on the windshield of the virtual lane corresponding to the location of the lane must be performed, installation and operation are complicated, the cost burden increases, and the calculation processing is complicated. do.

1 is a flowchart illustrating a lane display method disclosed in Korean Patent Registration No. 10-1767434 (Title of the Invention: Lane Display Apparatus and Method Using Head-Up Display).

In the lane display method (hereinafter referred to as the prior art) of FIG. 1 ( S100 ), the control unit receives the front image of the vehicle from the image capturing unit ( S110 ) and extracts the lane from the front image input at the step S110 ( S110 ) After recognizing the lane in step S20 and S120 step S120, comparing the lane reliability with the set value in steps 130 (S130) and comparing the lane reliability and the set value in step 130 (S130) Thus, when the lane reliability is less than or equal to the set value, the virtual lane is converted into augmented reality in accordance with the step 140 (S140) of analyzing the type of lane to display the lane on the head-up display, and the color of the lane and the location of the actual lane. In step 150 (S150) of determining the position of the lane to be displayed on the heads-up display, and in step 150 (S150), when the color and location of the lane to be displayed on the head-up display are determined, an image of the lane according to the type of lane is generated It consists of a step 160 (S160) and a step 170 (S170) of displaying the image of the lane generated in step 160 (S160) on the head-up display.

In this case, step 130 (S130) compares the lane reliability with a set value and ends without displaying a lane on the head-up display when the lane reliability exceeds the set value.

The prior art (S100) configured as described above recognizes the lane from the front image and analyzes the type, sets the type and color of the lane, and displays the lane by overlapping the lane of the road. It has the advantage of improving the visibility of the lane.

However, the prior art (S100) has disadvantages in that the installation and operation are complicated and cumbersome, and the cost increases because the image capturing unit for photographing the front of the vehicle must be installed on the vehicle body.

In addition, the prior art ( S100 ) has a disadvantage in that the calculation process is complicated because a control unit that analyzes the image obtained by the image capturing unit to set the type and color of the lane and displays it overlapping the lane of the road must be installed.

In general, even in the same vehicle and in the same lane, the driver's field of view is formed differently depending on external factors such as the driver's sitting height and the angle of rotation of the driver's seat backrest. That is, the driver with a short sitting height has a relatively low field of view looking at the lane compared to a driver with a relatively tall seated height, and accordingly, the position on the windshield corresponding to the field of view is formed at a low position. .

However, since the prior art (S100) does not take these external factors into account at all, due to these external factors, the lanes of the road and the displayed lane images do not match, rather confounding and obstructing the driver's view, causing a traffic accident. Occurs.

In addition, the prior art (S100) has a structural limitation of increasing the power consumption of the vehicle because each component of the image capturing unit, the control unit, and the head-up display is operated using the vehicle battery.
