Description

System for operating guide of cars

More particularly, the present invention relates to a guide for driving a vehicle, and more particularly, it relates to a vehicle guiding device that visually and audibly instructs a driver to adjust a traveling direction of a vehicle when a car moving in a curved ramp is likely to collide with a side wall of a curved ramp, To a device and system for preventing collision with a side wall of a ramp.

Cars are convenient and useful for moving passengers and goods, but they must be parked at a designated location when not in use. Cars can not be parked anywhere because of their volume, and they should be parked in specially designated places, such as parking lots. Parking lots are installed in large buildings such as apartments, department stores, large marts and officetels, and parking problems can be solved simply by driving the car and moving to the parking lot.

1B is an embodiment in which a curved ramp 110-1 is installed on the outer side of a parking building 120-1 on the ground, FIG. 1B is an embodiment in which a curved ramp 110-2 is installed on a ground parking building or an underground parking building An example in which the curved ramp 110-3 is installed at the inner center of the parking building 120-2, and the curved ramp 110-3 is installed at the inner side of the parking building 120-3 from Fig. 1C.

As illustrated in FIG. 1, it is general and common sense that designing a ramp through a curved (and thus curved ramp) ramp to travel to a parking lot can effectively use a narrow space. According to Article 6 of the Enforcement Regulations of the Parking Lot Act (the structure and equipment standard of the out-door parking lot), parking lot entrance roads, curved roads, are built with a width of 3.3 ~ 3.6m (meters)

If the width of the straight passage is 3.3 ~ 3.6m, there is no problem to move the car. However, when the width of the curved ramp is 3.3 ~ 3.6m, it is difficult for the novice driver to move the car along the curved ramp, It is easy to expect that drivers who are familiar with driving will have to pay considerable attention when moving along the ramp. In addition to these inconveniences, it is also expected that a car moving along a curved ramp will collide with the side of the curved ramp to the side of the car, thereby damaging both the car and the side wall.

Recently, newly built apartments and business buildings tend to decorate entrance and parking lots in order to increase the value of the building. Since there is a sign of accident on the side of the curved ramp that the car moves, There is a proposed solution.

Open Patent No. 10-2009-0122850 relates to an illegal parking prevention and parking convenience system, in which an ultrasonic sensor is used to display the distance between a wall and a vehicle through an LCD, thereby allowing the driver to park more conveniently and prevent collision .

However, the disclosed invention includes the inconvenience that the driver must always focus on the marked distance when parking, since it only displays the distance and does not give any warning.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicle operation guide device for projecting a center display line on a curved ramp to a central portion of a curved ramp and projecting a vehicle center display line onto a vehicle.

Another object of the present invention is to provide a vehicle driving guide system including the vehicle driving guide device, the vehicle width detection sensor, and vehicle progress instruction means for generating a vehicle progress instruction signal indicating a correct traveling direction of the vehicle .

According to an aspect of the present invention, there is provided a guide device for a vehicle, including at least one of a first guide line display means and a second guide line display means. The first guide line display means is installed on the upper side of the curved ramp or the side wall of the curved ramp so as to sense the width of the curved ramp and project the center display line with a curved ramp at the center of the curved ramp. The second guide line display means is installed on the upper side of the curved ramp or the side wall of the curved ramp to detect the width and position of the vehicle in operation in real time and displays the vehicle center Project the line in real time. The curved ramp center display line and the vehicle center display line are visually displayed in different colors.

According to another aspect of the present invention, there is provided a vehicle driving guide system, comprising: a plurality of the vehicle driving guide devices and the curved ramp, And vehicle progress instruction means for comparing the center display line with the vehicle center display line and transmitting a vehicle progress instruction signal indicating the correct traveling direction of the vehicle to the driver.

The use of the vehicle driving guide device and the vehicle driving guide system according to the present invention enables the driver to avoid collision with the side wall of the curved ramp through audible warning as well as visual warning, In addition, since the damage caused by the collision to the side wall of the curved ramp is suppressed as much as possible from the viewpoint of the manager of the facility, the cost required when the accident occurs can be minimized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like reference symbols in the drawings denote like elements.

2 is an embodiment of a vehicle driving guide system according to the present invention.

Referring to FIG. 2, the vehicle driving guide system 200 according to the present invention can be broadly classified into a vehicle driving guide device 210 and a vehicle progress instruction device 250.

The vehicle driving guide device 210 includes a first guideline display means 220 and a second guideline display means 230.

The first guide line display means 220 is provided on the upper side of the curved ramp or on the side wall of the curved ramp to sense the width of the curved ramp and then project the center display line with a curved ramp at the center of the curved ramp A first sensor 221 for detecting the width of the curved ramp for this purpose, and ramp centerline information indicating the center of the curved ramp using information on the width of the curved ramp received from the first sensor 221 And a first laser point 223 for generating and projecting a curved ramp center display line corresponding to the ramp center line information to the center of the curved ramp.

The second guide line display means 230 is installed on the upper side of the curved ramp or on the side wall of the curved ramp to sense the width and position of the vehicle in operation, A second sensing sensor 231 for sensing the width and the position of the vehicle in operation in real time for performing the function of projecting the display line, a vehicle center line A second signal processing unit 232 for calculating information in real time, and a second laser point 233 for projecting a vehicle center display line, which changes in real time corresponding to vehicle center line information, to the center of the vehicle.

On the other hand, although not shown in the drawings, a camera may be used instead of the second sensing sensor 231. The second signal processing device 232 can calculate the position of the vehicle and the distance from the vehicle to the wall surface through the image of the vehicle taken by the camera, And controls the second laser point 233 to project the center display line to the center of the vehicle.

At this time, it is preferable that the center display line and the vehicle center display line of the curved ramp are displayed in visually different colors, which will be described later.

The first guideline display means 220 includes a first sensing sensor 221 capable of recognizing the width of the curved ramp on which the first guideline display means 220 is installed, And the first signal processing device 222 for calculating the inclination center line information indicating the center of the curved ramp using the information of the width of the ramp, the installer does not need to consider the width of the curved ramp at the installation place There are advantages. In other words, if the first sensor 221 and the first signal processor 222 are not provided, the projection direction of the laser point should be automatically adjusted manually or by using a separate device depending on the installation location.

In addition, the second guide line display means 230 also includes a second sensing sensor 231 for sensing in real time the width and position of the vehicle in operation, a vehicle center line Since the second signal processing device 232 for calculating information in real time is included, there is an advantage that the width of the vehicle entering the curved ramp need not be separately considered.

The first laser point 223 and the second laser point 233 output a laser beam to project a certain display line. However, the first laser point 223 is installed only once the center display line is determined with a curved ramp The vehicle center display line output from the second laser point 233 must be changed in real time because the position of the vehicle moving in the curved ramp changes in real time while the output laser beam remains unchanged The output direction of the beam is different in that it must be changed in real time.

In the above description, both of the two laser points 223 and 233 are used. However, even in the case of using only the first laser point 223 and the case of using only the second laser point 233, Can be obtained. That is, when only the first laser point 223 is used, the center display line is projected with a curved ramp at the center of the curved ramp, so that the driver can suppress the collision by operating the center display line with reference to the curved ramp. In the case of using only the second laser point 233, even if the center display line is not projected on the curved ramp, referring to the vehicle center display line, the center of the vehicle can be matched to the imaginary center of the curved ramp, A predetermined effect of suppressing collision can be expected.

A plurality of vehicle progress instruction means (250) are provided on the upper side of the curved ramp or on the side walls of the curved ramp. The vehicle progress instruction means (250) compares the center display line and the vehicle center display line with a curved ramp, And includes a line comparison device 251, a third signal processing device 252, a speaker 253, and an automobile sensor guide 254 for conveying the signal to the driver.

The line comparing device 251 compares the center display line and the vehicle center display line with a curved ramp to generate a comparison signal. The third signal processing device 252 generates an instruction signal instructing to fix or modify the position of the vehicle in response to the comparison signal. A plurality of speakers 253 are provided on the upper side of the curved ramp or the side walls of the curved ramp, and display the vehicle progress instruction signal in voice or sound according to the instruction signal.

A plurality of vehicle guide sensor guides 254 are provided on the side wall of the curved ramp. The vehicle guide sensor 254 displays a vehicle progress instruction signal by flashing light or displaying a warning message in response to the instruction signal, and blinks the light in response to the approach detection signal The fourth signal processing device 256, the LED panel 257, the second signal processing device 256, the second signal processing device 256, A front panel 258, and a third laser point 259. As shown in FIG.

The vehicle detection sensor 255 generates an approach distance detection signal having information on whether the vehicle approaches the vehicle travel sensor guide 254 within a predetermined distance and information on the distance between the vehicle and the side of the curved ramp do. The fourth signal processing device 256 compares the access distance detection signal with a predetermined access limit distance to generate an access comparison signal. The LED panel 257 is provided with a plurality of LEDs that blink in response to an instruction signal or an approach detection signal. The light panel 258 displays a progress arrow indicating the traveling direction of the vehicle, or displays a warning in response to the approach comparison signal. The third laser point 259, in response to the instruction signal or the approach detection signal, instructs the bonnet of the vehicle to change the direction of the vehicle, such as an arrow, as a laser signal.

On the other hand, although not shown in the drawings, a camera may be used in place of the vehicle detection sensor 255. The fourth signal processor 256 can calculate the position of the vehicle and the distance from the vehicle to the wall surface through the image of the vehicle photographed by the camera. The distance between the calculated vehicle and the wall is set in advance, May be compared to generate an access comparison signal.

As described above, the vehicle driving guide system 200 according to the present invention can be roughly classified into a vehicle driving guide device 210 and a vehicle driving instruction device 250. The vehicle driving guide device 210 is a visual warning device, The vehicle progress instruction means 250 can prevent the driver from colliding with the side wall of the curved ramp by an audiovisual warning. Therefore, although collision prevention can be said to be most effective when used in combination, it can be easily predicted that a predetermined collision preventing effect can be obtained even when these are separately installed and used.

Fig. 3 shows an embodiment in which a vehicle driving guide system according to the present invention is installed.

Fig. 3A shows a conventional curved ramp in which only the protruding portion of the lighting installed on the upper portion of the road and the lower portions of the right and left side surfaces are covered with the induction paint.

FIG. 3B shows a state in which the vehicle progress instruction means 250 according to the present invention is installed on the side wall of the curved ramp of FIG. 3A. The LED panel 257 constituting the vehicle progress instruction means 250 illuminates the road surface of the curved ramp and the front panel 258 guides the traveling direction. The LED panel 257 is used to determine whether the vehicle has approached the vehicle progress instruction means 250 by a predetermined distance using the vehicle sensor 255 and the fourth signal processor 256 constituting the vehicle progress instruction means 250 It is possible to optimize the power consumed in illuminating the road surface of the curved ramp. Of course, the LED panel 257 can be controlled to emit light only when the vehicle is located within a certain distance from the corresponding LED panel 257, under the control of the vehicle sensor 255 and the fourth signal processor 256. The light is emitted only when the vehicle is located for a certain period of time or within a certain distance, so that it illuminates the vicinity of the entrance and exit walls only while the vehicle passes through, and is turned off after the vehicle passes, thereby saving electricity.

The vehicle detection sensor 255 generates an approach distance detection signal having information on the distance between the vehicle and the side of the curved ramp in addition to the approach detection signal having information on whether the vehicle approaches the vehicle travel sensor guide 254 within a predetermined distance do. The fourth signal processing device 256 compares the access distance detection signal with a predetermined access limit distance to generate an access comparison signal.

The access comparison signal has information on whether the vehicle traveling on the curved ramp approaches the side wall on which the vehicle travel sensor guide 254 is mounted and is closer to the predetermined distance or closer to the approach limit distance to possibly collide with the side wall have. For example, assuming that the access limit distance is set to 15 cm, if the vehicle is 18 cm away from the side wall from the approach distance detection signal, the access comparison signal contains information that the possibility of collision is low, Conversely, if the vehicle is 13 cm away from the side wall from the approach distance detection signal, it will contain information that there is a possibility of collision in the access comparison signal.

If the access comparison signal includes information indicating that there is a possibility of a collision, a warning message will be displayed instead of an arrow indicating the traveling direction of the vehicle to the electric panel 258 that normally guided the vehicle's traveling direction.

Fig. 4 shows an embodiment of vehicle progress instruction means according to the present invention.

4A shows a front panel 258 displaying an arrow for guiding the traveling direction of the vehicle and a warning display (left warning) indicating that the vehicle is approaching the left wall and is likely to collide with the left wall. In Fig. 4a, two front panel 258 are shown, except that the left panel is 10 inches and the right panel is 12 inches.

FIG. 4B is a wall-mounted type in which the front panel 258 displays a warning sign (right warning) or a danger of approaching black or displays green, thereby indicating that there is no problem in the progress of the vehicle.

Fig. 4C is a stand-type, and Fig. 4D is a wall-mounted type.

5 shows another embodiment of the vehicle progress instruction means according to the present invention.

Referring to FIG. 5, the vehicle progress indicator 250 may be implemented as a laser point 510 installed at an upper portion and an LED panel 257 provided at a lower portion of the speaker 253 in the middle. The laser point shown in the upper part can be set to emit a warning laser to the driver of the vehicle when it is judged that there is a possibility that the vehicle may collide with one side surface.

As described above, even in the configurations of Figs. 3B and 4, it is possible to prevent the vehicle from colliding with the side surface of the curved ramp when the driver enters the car park along the curved ramp. However, since it may be difficult to consider the left and right sides of the vehicle depending on the driver's driving experience and driving characteristics, the present invention proposes to selectively use the vehicle driving guide device 210 described later.

FIG. 6 shows an embodiment in which a vehicle operation guide device according to the present invention is installed in a curved ramp.

Referring to FIG. 6, a vehicle progress instruction unit 250 according to the present invention is installed on a side of a curved ramp, and a first guide line display unit 220 of an automobile travel guide unit 210 is further installed And the first guide line display means 220 is projecting a red laser line 610 at the center of the curved ramp, that is, the center display line at a curved ramp.

Fig. 7 shows an embodiment of a vehicle driving guide apparatus according to the present invention.

Referring to FIG. 7, two curved ramps are shown, which means an ascending line and a descending line. At the center of each curved ramp, a center display line with a curved ramp projected from the first guideline display means 220 It can be seen that they are projected in different colors. Although FIG. 7 is divided into red and green, this is for illustrative purposes only, and the color of the center display line can be variously selected by a curved ramp.

The curved ramp center display line shown in Figs. 6 and 7 means the center line of the curved ramp, which means the center portion from the left and right sides of the curved ramp. That is, if the center of the vehicle running on the curved ramp coincides with the center display line with a curved ramp, there is a minimum possibility that the vehicle will collide with the left and right sides of the curved ramp. It is difficult for an experienced driver to be sure whether the center of the vehicle that he or she is driving is coincident with the center display line on a curved ramp. Whether the novice driver or the driver of the large vehicle matches the center of the vehicle driven by the curved ramp to the center display line It is more difficult to be sure.

Therefore, in the present invention, the vehicle center display line indicating the center of the vehicle moving the curved ramp is projected in real time to the center of the vehicle, and the driver can visually compare the vehicle center display line and the curved ramp center display line, It is proposed to additionally use the following second guide line display means 230 so as to modify the proceeding direction.

Fig. 8 shows a curved ramp center display line and a vehicle center display line projected on the upper side of a moving vehicle in a curved ramp. Fig.

Referring to FIG. 8, it can be seen that the center display line and the vehicle center display line are projected in red and green on the curved ramp on the upper surface of the vehicle. If the curved ramp indicates that the center display line is green and the vehicle center display line is red, then the vehicle is biased to the left of the curve ramp.

At this time, the line comparison device 251 constituting the vehicle progress instruction means 250 compares the center display line and the vehicle center display line with a curved ramp to generate a comparison signal, and the third signal processing device 252 compares the comparison signal response Thereby generating an instruction signal instructing to fix or correct the position of the vehicle. The indicating signal may be implemented by at least one of a speaker 253 for generating a voice or an acoustic signal and an electric panel 258 for generating an optical signal.

When the indicating signal is activated, the speaker 253 may warn the driver by outputting a voice or sound signal about the possibility of the vehicle colliding with the left wall or the right wall. The embodiment that warns the front panel 258 has already been mentioned in the description of FIG. 4, and therefore will not be described here.

5, the laser point 510 on the upper part of the vehicle progress instruction means 250 shown in FIG. 5 displays a display instructing to change the traveling direction of the vehicle in the direction of the arrow when the instruction signal is activated, To the top of the bonnet. When the arrow is pointing to the left, the vehicle is instructed to change its direction to the left because the vehicle is shifted to the right, and when the arrow is pointing to the right, it is instructed to reverse the vehicle to the right. When projecting an arrow using a laser light, care should be taken that the arrow is not projected directly onto the eyes of the driver or the person sitting next to the driver.

Referring to FIG. 8, a curved ramp center display line and a vehicle center display line are projected onto the interior of the vehicle as well as the upper portion of the bonnet, which is an area that can be visually recognized by the driver. Accordingly, when the driver warns the warning of the vehicle progress instruction means 250 installed on the left and right walls of the vehicle and drives the center display line and the vehicle center display line to coincide with each other at a curved slope, It can be effectively prevented.

9 shows an embodiment of the laser point constituting the guideline display means according to the present invention.

9A shows a first laser point 223 projecting red color and FIG. 9B shows a second laser point 233 projecting green. A first laser point 223 projecting red is used in the embodiment already shown in Fig. 6 shows an embodiment in which only a first laser point 223 for projecting red color is used. The second laser point 233 for projecting green light has a first laser point 223 projecting a red color, But it is also possible to install them in parallel.

At this time, the colors of the two laser points should be different from each other so that the driver can distinguish the center display line and the vehicle center display line from the curved ramp.

The actual curved ramp may be a one-lane one-way lane or a one-lane two-lane traffic lane. However, the vehicle driving guide device 210 and the vehicle progress instruction device 250 may be installed at appropriate intervals, It is preferable to be determined according to the width, inclination and curvature of the ramp.

For example, the vehicle travel guide device 210 is installed at regular intervals on the upper side of the curved ramp or on the side of the curved ramp depending on the width, inclination, and curvature of the curved ramp. The speaker 253 constituting the vehicle progress instruction means 250 is installed at regular intervals on the upper side of the curved ramp or on the side of the curved ramp depending on the width, the inclination and the curvature of the curved ramp, Are installed at regular intervals on the sides of the curved ramp according to the width, inclination and curvature of the curved ramp.

While the present invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope of the present invention.
