Description

The present invention relates to a parking line display device.

As a parking line display device, a road surface light emitting block embedded in the ground can be adopted (see, for example, Patent Document 1). This road surface light emitting block has a surface light emitting portion that diffuses light from an LED as a light source body to emit light on the entire surface. Since the entire surface emits light, the visibility is excellent as compared with a device in which each LED emits point light, and it is suitable for guidance / warning.

JP-A-2009-230756

However, in Patent Document 1, since the LED is arranged below the surface light emitting portion, when embedding the road surface light emitting block, the depth of the recess for accommodating the road surface light emitting block becomes deep, which takes time and effort for construction. Was there.

The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a parking line display device that can be easily installed.

Hereinafter, effective means and the like for solving the above problems will be described while showing actions, effects and the like as necessary. In the following, for the sake of easy understanding, the reference numerals of the corresponding configurations in the embodiment of the invention are appropriately shown in parentheses or the like, but the present invention is not limited to the specific configurations shown in the parentheses or the like.

The first invention is a parking line display device (20) provided in a recess (19) extending continuously or discontinuously in the vehicle traveling direction in a parking area, and is a light emitting unit (20) arranged in the recess and emitting surface light. The light emitting unit includes a light emitting unit (41) provided with the light emitting surface (41a) facing upward, and a light source body (42) provided on the side portions (41b, 41c) of the light emitting unit. And, characterized by having.

Therefore, when the vehicle is parked, the light emitting portion arranged in the concave portion extending continuously or discontinuously in the vehicle traveling direction is surface-emitting to serve as a guide for the vehicle traveling direction. Further, since the light source body is provided on the side portion of the light guide portion, the depth of the recess can be made shallow. This facilitates the provision of recesses for the parking line display device.

In the second invention, the light emitting unit has a plurality of light source units arranged continuously in a line shape, and the light source unit has a long shape extending in the vehicle traveling direction. A holding member (43) for holding the light source body is attached to a side portion, and the holding member holds a plurality of the light source bodies in a direction along the longitudinal direction of the light guide portion, and the light guide portion. It is characterized by having a length shorter than the length in the longitudinal direction of the light source.

In the light emitting unit, in a configuration in which a plurality of light guide units are continuously arranged in a line shape, for example, by causing each light guide unit to emit light individually, it is possible to realize a wide variety of light emitting modes.

Further, each light guide unit is individually provided with a light source body, and electrical wiring is connected to the light source body. In this case, in a configuration in which a plurality of light guide portions are continuously arranged, since the holding member has a length shorter than the length in the longitudinal direction of the light guide portion, the holding member is located on the side portion of the light guide portion. In the state where the light guide is attached, a wiring space in which the holding member does not exist is formed for each light guide on the side of the light guide. Thereby, for example, the electric wiring connected to the light source body can be passed below or above the light guide portion from the wiring space. Therefore, it is possible to prevent the electrical wiring from the light source body from becoming an obstacle in the state where the light guide portions are continuously arranged.

In the third invention, the holding member includes a first holding member (43b) and a second holding member (43c), which are attached to both side portions of the light guide portion in the lateral direction, respectively. The first holding member is attached with one end in the longitudinal direction aligned with one end (41e) of the light guide, and the second holding member has one end in the longitudinal direction of the light guide. It is characterized in that it is attached in a state of being aligned with the other end portion (41f) of the portion.

Light source bodies are held by holding members on both sides of the light guide portion. Therefore, for example, by causing the light source bodies on both sides to emit light, the brightness of the light emitting surface can be increased, and the difference in brightness from the ground can be further increased. Therefore, it becomes easy to use as a guide when parking.

Further, holding members are alternately provided on both side portions of the light guide portion. Therefore, the light source body is held on one of the side portions of the light guide portion in the longitudinal direction. As a result, when a plurality of light guide portions are continuously arranged, it is possible to prevent the light source body from being held at the joint between the light guide portion and the light guide portion, and the brightness suddenly decreases at the joint. Can be suppressed. Therefore, the light emitting surface becomes a continuous line shape, and it is possible to easily recognize the vehicle traveling direction.

In the fourth invention, the light guide portion has a long shape extending in the vehicle traveling direction, and a holding member (43) for holding the light source body is attached to a side portion thereof. Each of the holding members has a first holding member (43b) and a second holding member (43c) attached to both sides of the light guide portion in the lateral direction, and the holding members have different emission colors. The light source bodies (42a, 42b) of the above are held.

As a result, it is possible to emit light in a plurality of colors. Further, since the emission color is different for each holding member, the emission color can be changed by causing each holding member to emit light, which simplifies control.

A fifth aspect of the present invention is characterized in that the bottom portion (19d) of the recess is provided with a pedestal member (30) that holds the light guide portion at a position above the bottom portion.

As a result, even if water enters the recess, the inconvenience that the light guide portion is immediately immersed in water can be suppressed.

In the sixth invention, the opening (19a) of the recess is provided with a lid member (50) that covers the opening while transmitting light from the light guide, and the lid member is provided with a lid member (50). It is characterized in that it is provided so as to be separated from the light emitting portion.

Even if a load acts on the lid member from above, the lid member is separated from the light emitting portion, so that the load on the lid member is not directly transmitted to the light emitting portion. Therefore, the light emitting portion can be protected by the lid member.

According to a seventh aspect of the present invention, the parking area is provided inside the garage (12), and the light emitting portion is also arranged in the recess provided along the vehicle traveling direction to the garage. It is characterized by.

This makes it easier to recognize the direction of travel of the vehicle to the garage and makes it easier to prevent contact with the garage.

An eighth invention includes a control device (60) for controlling light emission of the light source body, and the control device causes light emission based on the light emission request when a light emission request is made due to parking of the vehicle. It is a feature.

As a result, when a light emission request is made due to the parking of the vehicle, the light source body emits light. For this reason, the light emitting part is usually inconspicuous and the aesthetic appearance is improved.

A ninth aspect of the present invention is characterized in that the control device determines the presence or absence of a suspicious person, and when it is determined that there is a suspicious person, causes the light source body to emit light in a predetermined alarm pattern.

As a result, the parking line display device can be used to inform the surroundings that a suspicious person is present.

Hereinafter, an embodiment embodying the present invention will be described. FIG. 1 is a diagram showing a building with a garage. As shown in FIG. 1, a building 10 such as a house is provided on the site, and the building 10 is provided with an indoor space portion 11 such as a living room or a living room, and a garage 12 as a so-called inner garage. The inside of the garage 12 is a parking area. The vehicle entrance 13 of the garage 12 faces the entrance space 14 provided in the site, and the entrance space 14 faces the road 15 outside the site. A parking position PA having a rectangular shape in a plan view is determined in the garage 12, and the vehicle V is parked at the parking position PA. In the present embodiment, the parking position PA has a width and a depth capable of parking one automobile, and is surrounded by a wall 16 (side wall 16a and back wall 16b) except for the vehicle entrance / exit 13.

The entrance space 14 has a rectangular shape in a plan view. The width of the entrance space 14 (the width in the left-right direction in FIG. 1) is wider than the width of the garage 12. Further, in the extended portion of the entrance space 14 that is extended with respect to the width of the garage 12, a entrance 17 that allows entry and exit to the indoor space portion 11 is arranged. It is possible to enter and exit the indoor space portion 11 through the entrance 17. Further, the entrance door 17 is provided with the entrance door 18. The entrance door 18 includes a hinged door that can rotate to the outdoor side.

The floors of the garage 12 and the entrance space 14 are paved with, for example, concrete or brick. A pair of left and right storage recesses 19 extending continuously in the vehicle traveling direction are provided on the floors of the garage 12 and the entrance space 14, and a parking line display device 20 is embedded in the storage recesses 19. The parking line display device 20 has a function of displaying a line that serves as a guide for the vehicle traveling direction of the vehicle V when the vehicle V is parked at the parking position PA. The details will be described below.

FIG. 2 is a cross-sectional view taken along the line AA of FIG. 1 showing a schematic configuration of the parking line display device 20. In the present embodiment, the parking line display device 20 includes a pedestal member 30 provided in the accommodation recess 19, a light emitting portion 40 provided in the accommodation recess 19 to emit light, and a lid member 50 covering the opening 19a of the accommodation recess 19. Be prepared.

First, a storage recess 19 in which the parking line display device 20 is housed will be described. As shown in FIG. 1, the pair of left and right accommodating recesses 19 are provided so as to extend in parallel along the side wall 16a of the garage 12. Each storage recess 19 extends straight from the parking position PA of the garage 12 to the entrance space 14 outside the garage 12. That is, each accommodating recess 19 is provided along the vehicle traveling direction to the garage 12.

Further, in the width direction (left-right direction in FIG. 1), each storage recess 19 is provided outside the parking position PA. That is, the parking position PA is located inside the pair of left and right storage recesses 19. The width L1 (see FIG. 1) of each accommodating recess 19 is narrower than the tire width of a general vehicle. The housing recess 19 has, for example, a width of 10 to 20 cm and a depth of 5 to 10 cm.

As shown in FIG. 2, thin plate-shaped side wall plates 21 are provided on the left and right side wall surfaces 19b of the groove-shaped accommodating recesses 19. The side wall plate 21 is made of iron and is provided over the entire surface of the side wall 19b of the accommodating recess 19. The side wall plate 21 is matched to the shape of the side wall 19b of the accommodating recess 19. The side wall plate 21 protects the side wall 19b of the accommodating recess 19. Further, the accommodating recess 19 is provided with one step portion 19c protruding inward of the accommodating recess 19 on each of the left and right sides.

Next, the pedestal member 30 will be described. The pedestal member 30 is arranged at the bottom 19d of the accommodating recess 19. The pedestal member 30 is made of, for example, channel steel. Further, the pedestal member 30 has a long shape, and is provided in a straight line shape along the accommodating recess 19 in the depth direction (vertical direction in FIG. 1). The pedestal member 30 is arranged at the bottom 19d of the accommodating recess 19 from the front side (road 15 side) to the back side (back wall 16b side). The pedestal member 30 is arranged so as to open downward (on the bottom 19d side of the accommodating recess 19).

Further, the width of the pedestal member 30 is narrower than the width of the bottom 19d of the accommodating recess 19. Then, at the bottom 19d of the accommodating recess 19, the side wall plate 21 and the pedestal member 30 are separated from each other. Therefore, a space X1 is formed between the pedestal member 30 and the side wall 19b (more specifically, the side wall plate 21) of the accommodating recess 19. This space X1 can be used to pass electrical wiring.

Then, the pedestal member 30 holds the light emitting portion 40 at a position above the bottom portion 19d of the accommodating recess 19. More specifically, the light emitting unit 40 is held on the pedestal member 30. As a result, even if water enters the storage recess 19, it flows into the space X1, so that the inconvenience that the light emitting unit 40 is immediately immersed in water can be suppressed.

Next, the light emitting unit 40 will be described. The light emitting unit 40 includes a light guide plate 41 as a light guide unit having a light emitting surface 41a that emits surface light, an LED (light emitting diode) 42 as a light source body, and a holder 43 as a holding member for holding the LED 42.

A plurality of light guide plates 41 (10 in this embodiment) are continuously arranged in a line shape. The light guide plate 41 is a long flat plate extending in the vehicle traveling direction. These plurality of light guide plates 41 are continuously arranged so that the longitudinal direction of the light guide plate 41 is along the vehicle traveling direction. The plate thickness (height) of the light guide plate 41 is constant. Then, the light guide plate 41 is held by the pedestal member 30 so that the light emitting surface 41a of the light guide plate 41 faces the upper surface.

The light guide plate 41 is made of acrylic and has light transmittance. The light guide plate 41 is processed to emit light incident from the side portions (side surfaces) 41b and 41c in the lateral direction from the light emitting surface 41a.

A reflective sheet 44 is attached to the lower surface 41d of the light guide plate 41. The reflective sheet 44 reflects the light emitted from the lower surface 41d of the light guide plate 41 and re-enters the light guide plate 41. As a result, more light is emitted from the light emitting surface 41a, and the brightness of the light emitting surface 41a is increased.

Holders 43 are attached to both side portions 41b and 41c of the light guide plate 41 in the lateral direction. In the following, the holder 43 attached to the right side portion 41b of the light guide plate 41 in FIG. 2 may be referred to as a first holder 43b (first holding member). Similarly, the holder 43 attached to the left side portion 41c of the light guide plate 41 may be referred to as a second holder 43c (second holding member).

The holder 43 holds a plurality of LEDs 42 in the direction along the longitudinal direction of the light guide plate 41. More specifically, as shown in FIG. 3, the holder 43 holds a plurality of LEDs 42 at predetermined intervals in the longitudinal direction. As a result, the entire surface of the light emitting surface 41a of the light guide plate 41 can be made to emit light. Therefore, when the light guide plate 41 is continuously arranged in the accommodating recess 19, when light is emitted, the light emitting surface 41a is continuously formed into one line, which is excellent in visibility. Further, since the holder 43 of the present embodiment is made of aluminum and has excellent heat dissipation, failure due to heat is unlikely to occur even if a plurality of LEDs 42 are held.

Further, the holder 43 holds the LED 42 so that the light from the LED 42 is incident on both side portions 41b and 41c of the light guide plate 41. As a result, when the LED 42 emits light, the light emitting surface 41a of the light guide plate 41 emits surface light. Further, since the LED 42 is held on both side portions 41b and 41c of the light guide plate 41, it is possible to increase the brightness of the light emitting surface 41a as compared with the case where the LED 42 is held only on one of the side portions 41b and 41c. It becomes.

The holder 43 has a U-shaped cross section, and is attached so as to surround the side portions 41b and 41c of the LED 42 and the light guide plate 41. Then, when the holder 43 is attached to the light guide plate 41, a space 43a in the holder for passing the electrical wiring is formed in the holder 43. Using the space 43a in the holder, the electrical wiring connected to each of the LEDs 42 is passed in the longitudinal direction of the holder 43. Further, since the end portion of the holder 43 in the longitudinal direction is open, the electrical wiring passing through the holder inner space 43a is drawn out from the end portion of the holder 43.

By the way, since the light guide plate 41 is continuously arranged, if the holder 43 is provided over the entire length in the longitudinal direction of the light guide plate 41, it interferes with the holder 43 attached to the other light guide plate 41, and the electrical wiring is provided. It cannot be pulled out from the end of the holder 43. Therefore, in the longitudinal direction, the holder 43 is made shorter than the light guide plate 41, and is arranged so that a wiring space for drawing out the electric wiring is formed at one end of the light guide plate 41. Is desirable.

However, since the LED 42 is not held by the holder 43 in the wiring space, if the wiring space is formed on both side portions 41b and 41c of the light guide plate 41, it may not be possible to emit light on the entire surface of the light emitting surface 41a. There is a possibility that the brightness will be low in the portion where the wiring space is provided. For example, when wiring spaces are formed on both side portions 41b and 41c at one end of the light guide plate 41, the LED 42 is not held at the end, so that the brightness is low at the end. In this case, even if the light guide plates 41 are arranged continuously, the brightness may be low at the end portion which is a joint, and the joint may be conspicuous.

Therefore, in the present embodiment, the first holder 43b and the second holder 43c are attached alternately in the longitudinal direction. Specifically, as shown in FIG. 3, the first holder 43b is attached in a state where one end thereof in the longitudinal direction is aligned with one end portion (end portion in the longitudinal direction) of the light guide plate 41. On the other hand, the second holder 43c is attached in a state where one end thereof in the longitudinal direction is aligned with the other end portion of the light guide plate 41. Since the lengths of the first holder 43b and the second holder 43c are shorter than the length of the light guide plate 41 in the longitudinal direction, the first holder 43b and the second holder 43c are attached alternately in the longitudinal direction. It becomes.

More specifically, the end portion of the first holder 43b in the longitudinal direction is positioned with one end portion (hereinafter referred to as the first end portion 41e) of the longitudinal end portions 41e and 41f of the light guide plate 41. It is matched. The right end in FIG. 3 is referred to as the first end 41e. Since the length of the first holder 43b is shorter than the length of the light guide plate 41, the first holder 43b is provided near the other end of the light guide plate 41 (hereinafter referred to as the second end 41f). Absent. That is, in the side portion 41b of the light guide plate 41 to which the first holder 43b is attached, a wiring space X2 open in the vertical direction is formed in the vicinity of the second end portion 41f of the light guide plate 41. Using this wiring space X2, the electrical wiring K1 is pulled out from the end of the first holder 43b and passed through the space X1 below the light emitting unit 40.

Similarly, the end portion of the second holder 43c is aligned with the second end portion 41f of the longitudinal end portions 41e and 41f of the light guide plate 41. Since the length of the second holder 43c is shorter than the length of the light guide plate 41, the second holder 43c is not provided near the first end portion 41e of the light guide plate 41. That is, in the side portion 41c of the light guide plate 41 to which the second holder 43c is attached, a wiring space X3 open in the vertical direction is formed in the vicinity of the first end portion 41e of the light guide plate 41. Using this wiring space X3, the electrical wiring K2 is pulled out from the end of the second holder 43c and passed through the space X1 below the light emitting unit 40.

Further, since the first holder 43b and the second holder 43c are attached alternately in the longitudinal direction, one of the side portions 41b and 41c is also provided in the vicinity of the longitudinal end portions 41e and 41f of the light guide plate 41. The LED 42 is held in the. This makes it possible to emit light on the entire surface of the light emitting surface 41a. Therefore, when a plurality of light guide plates 41 are continuously arranged, it is possible to prevent the LED 42 from being held at all at the joint between the light guide plate 41 and the light guide plate 41 (that is, the ends 41e and 41f of the light guide plate 41). However, it is possible to prevent the brightness from suddenly decreasing at the joint.

Further, the emission color of the LED 42 held by the first holder 43b and the emission color of the LED 42 held by the second holder 43c are different. More specifically, the first holder 43b holds the RGB LED 42a (full color LED), and the second holder 43c holds the white LED 42b. Thereby, the emission color can be changed.

Next, the lid member 50 will be described. As shown in FIG. 2, the lid member 50 includes a flat plate-shaped first lid member 51 and a flat plate-shaped second lid member 52. The lid member 50 is formed by superimposing the second lid member 52 on the first lid member 51. Then, the lid member 50 is mounted on the stepped portion 19c of the accommodating recess 19 via the side wall plate 21 so as to cover the opening 19a of the accommodating recess 19.

Further, the lid member 50 is provided over the entire area of the opening 19a of the accommodating recess 19 in the longitudinal direction. That is, the lid member 50 is continuously provided in a line along the accommodating recess 19.

The first lid member 51 is made of polycarbonate. Further, the first lid member 51 is translucent and milky white while having light transmission. Therefore, the light from the light emitting unit 40 passes through the first lid member 51. On the other hand, since the first lid member 51 covering the opening 19a of the storage recess 19 is translucent milky white, it becomes difficult for the light emitting portion 40 and the like housed in the storage recess 19 to be directly visually recognized. The lid is aesthetically pleasing.

The second lid member 52 is made of tempered glass, has light transmission, and is colorless and transparent. Therefore, the light that has passed through the first lid member 51 passes through the second lid member 52 as it is. That is, the light from the light emitting unit 40 passes through the second lid member 52 via the first lid member 51. Therefore, the lid member 50 covers the opening 19a of the accommodating recess 19 in a state where the light from the light guide plate 41 is transmitted. An aluminum frame 53 is provided on the peripheral edge of the second lid member 52. This frame 53 may be omitted.

The height L3 from the bottom 19d of the accommodating recess 19 to the light emitting portion 40 (the highest portion of the light emitting portion 40) is lower than the height L4 up to the stepped portion 19c. Therefore, even if the lid member 50 is placed on the stepped portion 19c, the lid member 50 is separated from the light emitting portion 40, and the lower surface of the lid member 50 (the lower surface of the first lid member 51) and the light emitting portion 40. A gap is formed between the and. As a result, even if a load acts on the lid member 50 from above, the load applied to the lid member 50 is not directly transmitted to the light emitting unit 40.

The thickness of the lid member 50 (the sum of the thickness of the first lid member 51 and the thickness of the second lid member 52) is substantially the same as the height L5 from the step portion 19c to the floor surface. Therefore, when the lid member 50 covers the opening 19a of the accommodating recess 19, the floor surface and the upper surface of the lid member 50 (the upper surface of the second lid member 52) become substantially flat, and the appearance is improved. Further, since it is flat, it does not trip over the lid member 50 or the accommodating recess 19.

The width of the opening 19a of the accommodating recess 19 (excluding the thickness of the side wall plate 21) and the width of the lid member 50 are substantially the same. Therefore, there is no gap between the lid member 50 and the side wall plate 21, and the appearance is improved.

The first lid member 51 may be composed of one member, or may be composed of a plurality of members arranged in succession. The same applies to the second lid member 52. Further, the sizes (lengths in the longitudinal direction) of the first lid member 51 and the second lid member 52 are made different, and the number of the first lid member 51 and the number of the second lid member 52 are made different. May be good.

Next, the electrical configuration of the parking line display device 20 will be described with reference to FIG. The parking line display device 20 includes a controller 60 as a control device for controlling the light emission of each LED 42. The controller 60 includes an RGB control unit 60a that controls the light emission of the RGB LED 42a and a white control unit 60b that controls the light emission of the white LED 42b.

The controller 60 includes a control means such as a CPU and a storage means such as a ROM or RAM. The storage means stores a program for causing the control means to execute various processes such as light emission processing related to light emission, and a light emission pattern for specifying the light emission mode of the light emitting surface 41a. The light emitting pattern includes, for example, a parking light emitting pattern corresponding to a light emitting request associated with parking and a warning light emitting pattern corresponding to a light emitting request accompanying abnormality detection. There are a plurality of types of light emitting patterns for parking. For example, when the driver or the like uses the automatic parking function, the light emitting pattern for automatic parking is selected, and the driver manually parks the vehicle V at the parking position PA. Has a light emission pattern for manual parking that is selected. The warning light emission pattern includes, for example, an alarm pattern selected when a suspicious person is detected. The light emitting mode of the light emitting surface 41a is, for example, a light emitting timing, a light emitting color, and a brightness. The automatic parking function is a function in which the vehicle V recognizes the parking position PA by an in-vehicle sensor or the like and autonomously (automatically) parks at the parking position PA.

The controller 60 is connected to each RGBLED 42a, and outputs a signal to make each RGBLED 42a emit light. The controller 60 is configured so that the RGBLED 42a can be identified for each light guide plate 41. Therefore, the controller 60 can control the light emission of the RGB LED 42a for each light guide plate 41. Further, the controller 60 is also connected to the white LED 42b in the same manner, and the light emission of the white LED 42b can be controlled for each light guide plate 41.

Further, the parking line display device 20 includes a power controller 61. The power controller 61 is connected so that the power supplied from the outside can be supplied to the controller 60. The controller 60 uses the electric power supplied from the power controller 61 to output a signal and cause the LED 42 to emit light.

Further, the controller 60 is configured to be able to input an abnormality detection signal as a light emission request accompanying abnormality detection from a sensor 62 provided in the site (in the present embodiment, the left side of the entrance space 14). The sensor 62 has a function of detecting a suspicious person in the premises (more specifically, the garage 12 and the entrance space 14), and when the suspicious person is detected, an abnormality detection signal is output to the controller 60.

Further, the controller 60 can input a request signal as a light emission request associated with parking wirelessly or preferentially from an operation terminal 63 operated by a driver or the like or an operation panel 64 provided in a building 10. The operation terminal 63 can output a request signal for automatic parking and a request signal for manual parking. The request signal for automatic parking is a signal for notifying a light emission request associated with parking using the automatic parking function, and the request signal for manual parking is a signal for notifying a light emission request associated with manual parking. is there. The operation terminal 63 outputs a request signal according to the operation when the operation button of the operation terminal 63 is operated by a driver or the like.

Next, based on FIG. 5, a light emitting process for causing the light emitting surface 41a of the light guide plate 41 to emit light will be described in order to display a line that serves as a guide for the vehicle traveling direction of the vehicle V. The light emitting process is executed by the controller 60 at predetermined intervals.

The controller 60 determines whether or not an abnormality detection signal has been input from the sensor 62 (step S101). That is, in step S101, the controller 60 determines the presence or absence of a suspicious person on the premises.

When the abnormality detection signal is input (step S101: Yes), the controller 60 determines that there is a suspicious person and selects a warning light emission pattern (step S109).

On the other hand, when the abnormality detection signal is not input (step S101: No), the controller 60 determines whether or not the request signal for parking is input from the operation terminal 63 (step S102). That is, the controller 60 determines whether or not a light emission request for parking has been made from the operation terminal 63. When the request signal is not input (step S102: No), the controller 60 ends the light emission processing.

On the other hand, when the request signal is input (step S102: Yes), the controller 60 selects the parking light emitting pattern according to the type of the input request signal (step S103). Specifically, the controller 60 selects the automatic parking light emitting pattern when the request signal for automatic parking is input, and selects the manual parking light emitting pattern when the request signal for manual parking is input. The selected parking light emitting pattern is stored in the storage means of the controller 60.

Next, the controller 60 determines whether or not the request signal for automatic parking has been input (step S104). When the request signal for automatic parking is input (step S104: Yes), the controller 60 selects to make the light emitting surface 41a emit light with high brightness (step S105). When it is selected to emit light from the light emitting surface 41a with high brightness, information (flag or the like) indicating that fact is stored in the storage means of the controller 60.

On the other hand, after the processing of step S109 or when the request signal for automatic parking is not input (step S104: No), that is, when the request signal for manual parking is input, the controller 60 is at night. It is determined whether or not there is (step S106). Whether or not it is nighttime may be determined by the controller 60 based on the time, or may be determined based on the detected illuminance by providing an illuminance sensor.

At night (step S106: Yes), the controller 60 chooses to emit light from the light emitting surface 41a at low brightness (step S107). When it is selected to emit light from the light emitting surface 41a with low brightness, information (flag or the like) indicating that fact is stored in the storage means of the controller 60.

On the other hand, when it is not at night (step S106: No), that is, when it is daytime, the controller 60 performs the process of step S105.

Then, after performing the process of step S105 or step S107, the controller 60 controls the light emission of each LED 42 (step S108). In step S108, the controller 60 controls the light emission of each LED 42 so that the light emitting surface 41a emits light in the light emitting mode specified by the light emitting pattern stored in the storage means. At that time, when the storage means stores information indicating that the light emitting surface 41a is to emit light at high brightness, the controller 60 causes the light emitting surface 41a to emit light at high brightness. When the storage means stores information indicating that the light emitting surface 41a is to emit light at low brightness, the controller 60 causes the light emitting surface 41a to emit light at low brightness.

In the present embodiment, when the brightness of the light emitting surface 41a is increased, the voltage applied to each LED 42 is increased as compared with the case where the brightness of the light emitting surface 41a is decreased. As another example, when the brightness of the light emitting surface 41a is increased, the number of LEDs 42 to be emitted by each light guide plate 41 may be increased as compared with the case where the brightness of the light emitting surface 41a is decreased.

By executing such a light emitting process, when the operation terminal 63 is operated and a request signal for automatic parking is output, the light emitting surface 41a is made to emit light in a light emitting mode specified by the light emitting pattern for automatic parking. , The light emission of each LED 42 is controlled. When the light emission of each LED 42 is controlled so that the light emitting surface 41a emits light in the light emitting mode specified by the light emitting pattern for automatic parking, for example, all the light emitting surfaces 41a emit white light. For this reason, the light emitting unit 40 can usually be made inconspicuous, and the aesthetic appearance is improved.

Further, when the request signal for automatic parking is output, the brightness of the light emitting surface 41a is higher than that when the request signal for manual parking is output, and the light emitting surface 41a is in contact with the ground (the floor of the garage 12 and the entrance space 14). The difference in brightness becomes clear. When the difference in brightness between the ground and the light emitting surface 41a becomes clear, the vehicle V (vehicle-mounted sensor) can easily recognize the light emitting surface 41a. Therefore, the vehicle V (in-vehicle sensor) can easily recognize the parking position PA, and it is possible to support the vehicle V to park automatically.

Further, when the operation terminal 63 is operated and a request signal for manual parking is output, the light emission of each LED 42 is controlled so as to cause the light emitting surface 41a to emit light in the light emitting mode specified by the light emitting pattern for manual parking. To. When the light emission of each LED 42 is controlled so that the light emitting surface 41a emits light in the light emitting mode specified by the light emitting pattern for manual parking, for example, all the light emitting surfaces 41a emit blue light. When the request signal for manual parking is output, the brightness of the light emitting surface 41a is higher in the daytime and in the daytime than in the nighttime, and the ground (garage 12 and entrance space) even in the daytime. The difference in brightness from the 14 floors) becomes clear. At night, the brightness of the light emitting surface 41a is low, but since the surroundings are dark, the difference in brightness between the light emitting surface 41a and the ground becomes clear. Further, by lowering the brightness, the power consumption can be suppressed.

When the sensor 62 detects a suspicious person, the light emission of each LED 42 is controlled so that the light emitting surface 41a emits light in the light emitting mode specified by the alarm pattern. When the light emission of each LED 42 is controlled so as to make the light emitting surface 41a emit light in the light emitting mode specified by the alarm pattern, for example, all the light emitting surfaces 41a blink in red. As a result, the parking line display device 20 can be used to inform the surroundings that a suspicious person is present.

According to the present embodiment described in detail above, the following excellent effects can be obtained.

A light emitting unit 40 that is arranged in a housing recess 19 that extends continuously along the vehicle traveling direction when the vehicle V is parked at the parking position PA and emits surface light is provided. Then, by causing the light emitting unit 40 to emit light from the surface, a line extending along the vehicle traveling direction is displayed to the parking position PA, which serves as a guide for the vehicle traveling direction when the vehicle V is parked at the parking position PA.

Further, LEDs 42 are provided on the side portions 41b and 41c of the light guide plate 41. Therefore, the depth of the accommodating recess 19 can be made shallower as compared with the case where the LED 42 is arranged below the light guide plate 41. This facilitates the provision of the accommodation recess 19 for the parking line display device 20.

Further, since the holder 43 has a length shorter than the length in the longitudinal direction of the light guide plate 41, when the holder 43 is attached to the side portions 41b and 41c of the light guide plate 41, the side portions 41b and 41c of the light guide plate 41 are attached. In, wiring spaces X2 and X3 in which the holder 43 does not exist are formed for each light guide plate 41. As a result, the electrical wirings K1 and K2 connected to the LED 42 can be passed from the wiring spaces X2 and X3 to the space X1 below the light guide plate 41. Therefore, it is possible to prevent the electrical wirings K1 and K2 from the LED 42 from getting in the way when the light guide plates 41 are continuously arranged. This makes it easier to arrange the light guide plates 41 continuously.

The LED 42 is held by the holder 43 on both side portions 41b and 41c of the light guide plate 41, respectively. Therefore, for example, by causing the LEDs 42 on both sides 41b and 41c to emit light, the brightness of the light emitting surface 41a can be increased, and the difference in brightness from the ground can be further increased. Therefore, it becomes easy to use as a guide when parking.

Further, the holders 43 are alternately provided on both side portions 41b and 41c of the light guide plate 41. Therefore, at the longitudinal end portions 41e and 41f of the light guide plate 41, the LED 42 is held on one of the side portions 41b and 41c. As a result, when a plurality of light guide plates 41 are continuously arranged, it is possible to prevent the LED 42 from being held at the joints (ends 41e, 41f) of the light guide plates 41 and the light guide plates 41, and the brightness is increased at the joints. It is possible to prevent the sudden decrease. Therefore, the light emitting surface 41a becomes a continuous line shape, and it is possible to easily recognize the vehicle traveling direction.

Further, the light emitting unit 40 is arranged in the accommodation recess 19 extending from the parking position PA to the outside of the garage 12 (entrance space 14). Therefore, by making the light emitting unit 40 emit light from the surface, a line extending from the entrance space 14 to the parking position PA in the garage 12 along the vehicle traveling direction is displayed, so that the vehicle traveling direction can be recognized even outside the garage 12. It will be easier to do.

The controller 60 may be configured so that each LED 42 can be identified and the light emission of the LED 42 may be controlled. Similarly, the controller 60 may configure the LED 42 to be identifiable for each of the side portions 41b and 41c of the light guide plate 41, and control the light emission of the LED 42 for each of the side portions 41b and 41c. As a result, it is possible to realize a wide variety of light emitting modes at the parking position PA of the vehicle V.

As a result, the LED 42 can be held on the entire side portions 41b and 41c of the light guide plate 41, and the light emitting surface 41a can be made to emit light uniformly. In this case, in order to arrange the light guide plate 41 continuously, a space for drawing out the electric wiring may be provided on the upper surface of the holder 43 or the like. Further, when the lengths of the holder 43 and the light guide plate 41 are the same, the light guide plates 41 do not have to be continuously arranged in order to pull out the electric wiring from the end portion of the holder 43.

-In the above embodiment, the holder 43 is attached to both side portions 41b and 41c of the light guide plate 41, but the holder 43 may be attached to only one of the side portions.

-In the above embodiment, the holder 43 holds LEDs having different emission colors, but the same emission color may be used.

-The parking line display device 20 may be provided only inside the garage 12 (or only at the parking position PA). The length of the accommodating recess 19 is shortened, which facilitates construction.

The controller 60 causes the light emitting surface 41a to emit light when a light emission request is made, but the controller 60 may always emit light. For example, the controller 60 may always make the light emitting surface 41a emit white light. In this configuration, when a light emission request is made, the controller 60 may control the light emission of the LED 42 so as to change the light emission mode of the light emitting surface 41a based on the light emission request. For example, when an abnormality detection signal is input, the light emitting surface 41a may be made to emit light so as to change from white to red. Further, as long as the power is not turned off, the same light emission pattern may always be emitted. In this case, the power controller 61 may directly supply electric power to each LED 42, and the controller 60, the sensor 62, or the like may not be provided. As a result, the electrical configuration of the parking line display device 20 can be simplified.

-The type of light emitting pattern for parking and the light emitting mode specified by the light emitting pattern for parking may be arbitrarily changed. That is, the light emitting mode of the light emitting surface 41a when a light emitting request is made due to parking may be arbitrarily changed. For example, there may be a parking light emitting pattern in which the light emitting surface 41a sequentially emits light for each light guide plate 41. Further, there may be a parking light emitting pattern in which the light emitting color and the brightness of the light emitting surface 41a change with the passage of time. Further, there may be a parking light emitting pattern in which the light emitting surface 41a is repeatedly turned on and off. As a result, when parking, the light emitting mode is diversified, and the driver and the like can be entertained.

-The parking light emission pattern created by the user may be configured to be memorable.

-Although the type of the parking light emitting pattern was selected based on the type of the request signal, the parking light emitting pattern type may be selected by another method. For example, the type of the parking light emitting pattern may be selected by the lottery, or the type of the parking light emitting pattern may be selected depending on the current time. Further, for example, the type of the parking light emitting pattern may be selected depending on the type of the operation terminal that outputs the signal.

-A device other than the operation terminal 63 or the operation panel 64 may request light emission associated with parking. For example, the controller 60 includes a vehicle detection sensor that outputs a vehicle detection signal when the vehicle V is detected in the garage 12 or the entrance space 14, and the controller 60 is based on a predetermined parking light emitting pattern when the vehicle detection signal is input. , The light emission of the LED 42 may be controlled. When the vehicle V is detected, the light is emitted, so that the driver or the like does not have to operate the operation terminal 63 or the operation panel 64. Further, when a shutter is provided at the vehicle entrance / exit 13 of the garage 12, the controller 60 may control the light emission of the LED 42 based on a predetermined parking light emission pattern when the shutter is opened.

As a result, if the vehicle traveling direction of the vehicle V is not along the line, a warning is given, so that the vehicle V can be easily parked at the parking position PA.

-Similar to the parking light emitting pattern, the type of the warning light emitting pattern and the light emitting mode specified by the warning light emitting pattern may be arbitrarily changed.

-When a plurality of types of warning light emission patterns are provided, the selected warning light emission pattern may be changed according to the type of abnormality detection signal. For example, in addition to the sensor 62, a smoke detection device that outputs a smoke detection signal as an abnormality detection signal indicating that smoke is generated when smoke is detected is provided, and when the smoke detection signal is input. May select a fire warning emission pattern.

-The material of the light guide plate 41 is not limited to acrylic, and may be a material generally used for the light guide plate 41 such as polycarbonate.
