Is called. Thus, the driver can adjust the direction of the vehicle in accordance with the light until it approaches the parking space, and can pay attention to the protrusion from the doorway (for example, contact with the opening of the garage) after approaching the parking space. . Moreover, it can alert | report to a driver that it is approaching a parking space by the aspect of light emission changing. Accordingly, for example, attention can be given to a vehicle parked adjacently, an inner wall of a garage, or the like.

Means 4. The light source emits directional light;

Thereby, the display of the target position by light emission of the parking position guide part and the display of the approach route by the direct light from the light source can be suitably performed, and a practically preferable configuration can be realized. For example, the guidance of the approach route may be performed on the side that is the inner ring side of the vehicle. Normally, when moving a vehicle, it is assumed that the driver's line of sight is likely to be directed toward the center of rotation. As described above, by indicating the approach route on the inner ring side, that is, the rotation center side, the approach route can be easily recognized.

(First embodiment)
Below, the building with a garage which is one embodiment which actualized the invention is demonstrated, referring FIG. FIG. 1 is an explanatory diagram showing a schematic configuration of a garage portion of a house 10 which is a building with a garage and its surroundings, FIG. 1A is a front view of the house 10, and FIG. 1B is a cross-sectional view of the house 10. is there.

  As shown in FIG. 1, the house 10 is a two-story building (multi-story building), and a garage 11 is provided in the first-floor space. The garage 11 is an attached garage (inner garage) provided integrally with the house 10, and a parking space for one vehicle is secured in the garage 11.

  In the garage 11, a vehicle entrance / exit 13 having a substantially rectangular shape is formed on the outer wall surface 12 of the house 10, and the garage 11 communicates with the outside of the house 10 through the vehicle entrance / exit 13. That is, the entry / exit of the vehicle V (entrance and exit) is possible through the vehicle entrance 13. Further, on the back side of the garage 11, a ring stopper 14 is arranged on the floor surface. The wheel stopper 14 restricts the movement of the vehicle V toward the back. In a state where the movement of the vehicle V is restricted by the wheel stopper 14, the entire vehicle V is stored in the garage 11 (see FIG. 1B).

  The garage 11 is provided with a parking position guidance system that assists parking in the garage 11. As a specific configuration relating to the system, an entrance / exit light-emitting device 30 and a light source device 40 for displaying and displaying the vehicle entrance / exit 13 are provided. The entrance / exit light emitting device 30 and the light source device 40 are attached to a recess 21 formed at the edge of the vehicle entrance / exit 13 on the outer wall surface 12. More specifically, the recess 21 is recessed in a stepped shape toward the back side of the garage 11, and is formed along the edge of the vehicle entrance 13 on the entire periphery of the edge of the vehicle entrance 13. And the protrusion from the inner wall face of the garage 11 of the entrance / exit light-emitting device 30 grade | etc., Is suppressed by fitting the entrance / exit light-emitting device 30 and the light source device 40 in this recessed part 21. FIG. Thereby, the inconvenience that the vehicle V and the entrance / exit light-emitting device 30 and the like come into contact at the time of entering and leaving is less likely to occur. Hereinafter, the entrance / exit light-emitting device 30 will be described in detail.

  The entrance / exit light-emitting device 30 is disposed along the vehicle entrance / exit 13 and includes a light-transmitting member 31 having optical transparency. The light transmitting member 31 is formed by integrally forming a left and right vertical light emitting portion 32 extending in the vertical direction along the inner wall of the garage 11 and a horizontal light emitting portion 34 extending in the left and right direction along the ceiling. It has a frame shape that surrounds. That is, it is substantially U-shaped open to the floor surface side. The vertical light emitting section 32 and the horizontal light emitting section 34 have a shape corresponding to the concave portion 21 (specifically, a substantially rectangular parallelepiped shape), and are fitted in the concave portion 21.

  These left and right vertical light emitting portions 32 are arranged a predetermined distance apart from the floor surface of the garage 11. And the light source device 40 is arrange | positioned between the lower end part and floor surface of each vertical light emission part 32, respectively. A light incident port 35 is formed at a portion of the vertical light emitting unit 32 that faces the light source device 40, and light from the left and right light source devices 40 is transmitted through the light incident port 35 to the light transmitting member 31 (specifically, vertical light emission). Part 32). The left and right light source devices 40 have the same configuration. For convenience of explanation, the right side when viewing the garage 11 from the outdoor side is referred to as a “right light source device 40R”, and the left side is referred to as a “left light source device 40L”. I will call it. Similarly, regarding the vertical light emitting unit 32, the right side when the garage 11 is viewed from the outdoor side is also referred to as a “right vertical light emitting unit 32R”, and the left side is also referred to as a “left vertical light emitting unit 32L”.

  In addition, a reflector 37 that guides light incident from the vertical light emitting unit 32R to the horizontal light emitting unit 34 is provided at a boundary portion between the vertical light emitting unit 32R and the horizontal light emitting unit 34 on the right side. Specifically, the reflecting plate 37 is disposed in a state where the reflecting surface intersects both the longitudinal direction of the vertical light emitting unit 32R and the longitudinal direction of the lateral light emitting unit 34. The reflection plate 37 is fixed in a state where it is inserted into a hole formed in the light transmission member 31. The light that has passed through the right vertical light emitting unit 32R is reflected by the reflecting plate 37 toward the horizontal light emitting unit 34, whereby light can be supplied from the right light source device 40R to the horizontal light emitting unit 34. That is, the right light source device 40R supplies light to the right vertical light emitting unit 32R and the horizontal light emitting unit 34, and the left light source device 40L supplies light to the left vertical light emitting unit 32L. Thereby, the light supply to the entire area of the entrance / exit light emitting device 30 (specifically, the light transmitting member 31) is realized.

  A light reflecting member 39 constituting the entrance / exit light-emitting device 30 is provided in a portion of the left and right vertical light-emitting portions 32 and the horizontal light-emitting portion 34 facing the recess 21 (see FIG. 2A). The light reflecting member 39 reflects the light that passes through the light transmitting member 31 and diffuses toward the concave portion 21 toward the front of the vehicle entrance and the inside thereof. That is, the light emitted from the entrance / exit light-emitting device 30 is positively irradiated by the light reflecting member 39 toward the front and inward of the vehicle entrance / exit. The light reflecting member 39 is fixed to the light transmitting member 31 by attachment means such as adhesion. And the entrance / exit light-emitting device 30 integrated in this way is the state fixed to the recessed part 21 with fasteners, such as a screw.

  Next, the light source devices 40L and 40R will be described in detail with reference to FIG. 2A is a front view of the house 10 as in FIG. 1A, and is a schematic diagram showing the left light source device 40L and its surroundings in an enlarged manner, and FIG. 2B is the same as FIG. Similarly, it is the figure seen from the side of the house 10, Comprising: It is the schematic which expands and shows the left light source device 40L and its periphery, FIG.2 (c) is the schematic which looked at the left light source device 40L from the upper direction. Since both the light source devices 40L and 40R have the same configuration and differ only in the mounting direction, the left light source device 40L will be described first, and then the right light source device 40R will be briefly described including the difference in mounting direction.

  As described above, the left light source device 40L is disposed between the lower end of the left vertical light emitting unit 32 and the floor surface. Specifically, the height position is set to be approximately the same as the height position of the tire of the vehicle V parked in the garage 11.

  The light source device 40 includes a shaft portion 41 as an attachment portion with respect to the concave portion 21, and the light source device 40 is mounted by fixing the shaft portion 41 to the concave portion 21. The shaft portion 41 is set so that the center axis thereof faces the width direction (that is, the left-right direction) of the garage 11, and a movable portion 42 is attached to one end thereof. The movable portion 42 is pivotally supported by the shaft portion 41, and is rotatable about the shaft portion 41 (specifically, its central axis) (see FIGS. 2A and 2B). ).

  A light source 43 (hereinafter referred to as a laser light source 43) that emits laser light having a high directivity in a predetermined direction is attached to the movable portion 42. The light emitted from the laser light source 43 is composed of a single color, and the guidance by the laser light is always performed in the same color. In addition, as described above, the laser beam emission direction changes as the movable portion 42 rotates. Specifically, as indicated by the alternate long and short dash line in FIG. 2, laser light is emitted in the direct upward direction L1 and the outdoor horizontal direction L2. The laser light is directed to the direct upward direction L1, that is, the light incident port 35, so that the light transmission member 31 is irradiated with light, and the laser light is directed to the outdoor horizontal direction L2, that is, in front of the garage 11, so A guidance path is shown. Details of the display of the guide route by the laser light will be described later.

  In addition, light is directly irradiated to the driver by setting the height position of the light source device 40 to be approximately the same as the height position of the tire and emitting the laser light toward the outdoor horizontal direction L2. Is avoiding. Since dazzling can be suppressed by this, it is hard to produce the problem that it becomes difficult to drive | operate resulting from the display of a guidance route. Incidentally, it is also possible to direct the emission direction of the laser light downward from the horizontal direction. Further, instead of the laser light source 43, an LED or the like can be used as the light source.

  Further, the laser light source 43 is provided so as to be movable with respect to the movable portion 42. Specifically, the laser light source 43 is rotatable with respect to the movable portion 42, and the center axis thereof is set to be orthogonal to the center axis of the shaft portion 41. Thereby, the outdoor emission direction of the laser beam can be changed (that is, swinging irradiation is possible) (see FIG. 2C). As described above in detail, the light source device 40 has two rotation center axes that are orthogonal to each other and can be rotated in two different directions, so that the emission direction of the laser light can be set in the vertical direction, the horizontal direction, and the front-rear direction. It can be changed in each direction. The operation of the movable portion 42 with respect to the shaft portion 41 and the operation of the laser light source 43 with respect to the movable portion 42 are performed by an actuator or the like (not shown).

  In the right light source device 40R, the mounting direction with respect to the recess 21 is opposite to that of the left light source device 40L, but the basic configuration is the same. That is, similarly to the left light source device 40L, it has a shaft portion 41, a movable portion 42, and a laser light source 43, and the emission direction of the laser light can be changed.

  In these light source devices 40L and 40R, the emission direction of the laser light is defined in advance. That is, the light is emitted toward the light incident port 35 of the entrance / exit light-emitting device 30 in the directly upward direction L1, and in the outdoor horizontal direction L2, the front of the garage 11, the right diagonal front of the garage 11 and the diagonally left front of the garage 11 are three. It is stipulated to be selectively ejected in one of two different directions. Further, when the laser beams are emitted in the outdoor horizontal direction L2, the two laser beams are set to be parallel to each other.

  The emission direction of the laser light in the light source devices 40L and 40R is changed based on the position of the vehicle V toward the garage 11. Hereinafter, a configuration for acquiring the position information of the vehicle V will be described in detail.

  Referring to FIG. 1 again, a vehicle position detection device 60 for detecting the position of the vehicle V is provided above the vehicle entrance 13 and in the center in the width direction of the vehicle entrance 13. The vehicle position detection device 60 includes a non-contact sensor (specifically, an ultrasonic sensor) (not shown). The ultrasonic sensor is composed of an ultrasonic transmitter and an ultrasonic receiver, and the ultrasonic wave transmitted from the ultrasonic transmitter to the front of the garage 11 is reflected and then received by the ultrasonic receiver. Thus, it is possible to grasp that some detection target exists. More specifically, the distance to the detection target (vehicle V) is measured by measuring the reflection time. Particularly in the present embodiment, a plurality of ultrasonic transmitters are arranged in the width direction of the garage 11, and vehicle detection in a wide area in front of the garage 11 is possible. Further, a plurality of ultrasonic receivers are arranged in parallel in the width direction of the garage 11. By providing a plurality of transmitters and receivers in this way, it is possible to specify in which direction viewed from the vehicle position detection device 60, that is, the approach direction of the vehicle V with respect to the garage 11. ing.

  It should be noted that an optical range sensor such as a laser scanner can be used instead of the ultrasonic sensor as the detecting means for detecting the position of the vehicle V.

  As shown in FIG. 1B, the vehicle position detection device 60 described above is electrically connected to the control device 70, and the detection information of the vehicle V grasped by the vehicle position detection device 60 is the control device 70. Sent to. Specifically, the distance from the vehicle position detection device 60 to the vehicle V and its direction are output to the control device 70. The control device 70 is connected to the light source device 40, and the emission direction of the laser light in the light source device 40 is changed based on the detection result.

  Here, based on FIG. 3 (schematic diagram showing the detection area of the vehicle position), the detection area where the vehicle V is detected by the vehicle position detection device 60 will be described in detail.

  As shown in FIG. 3, the detection area of the vehicle position detection device 60 is set so as to spread radially (semi-circular) in front of the garage 11 with the vehicle position detection device 60 as the center. More specifically, the detection area is divided into three areas from the side closer to the vehicle entrance 13 to the side farther from the side. A first area E1 adjacent to the vehicle entrance 13 is provided in front of the vehicle entrance 13, and a second area E2 is provided outside the first area E2. A third area E3 is provided outside the second area E2. The radius dimension of the first area E1 is set to be smaller than the overall length dimension of the vehicle V. When the vehicle V exists in the first area E1, the garage 11 and the vehicle V are in close proximity. Indicates that Further, the length of the second area E2 and the third area E3 in the radial direction is set to be sufficiently larger than the total length of the vehicle V. After the detection result from the vehicle position detection device 60 is sent to the control device 70, the control device 70 determines in which area E1, E2, E3 the vehicle V exists. The detection area of the vehicle position detection device 60 is divided into three in the circumferential direction with the vehicle position detection device 60 as a reference. That is, a fan-shaped central area EM is set in front of the vehicle position detection device 60, and right and left sides of the central area EM are fan-shaped right area ER (the garage 11 from the front). A right side when viewed and a left side area EL (left side when the garage 11 is viewed from the front) are set. After the detection result from the vehicle position detection device 60 is sent to the control device 70, the control device 70 determines in which area EM, ER, EL the vehicle V exists.

  Next, control processing executed by the control device 70 will be described based on the flowchart shown in FIG. First, in step S101, it is determined whether or not the information from the vehicle position detection device 60 includes vehicle position detection information. If the position information is not included, the process returns to step S101, and step S101 is repeated until the position information is acquired. On the other hand, when the position information of the vehicle V is included, the distance between the garage 11 and the vehicle V is calculated. Based on this information, in step S102 and subsequent steps, it is determined in which of the areas E1 to E3 the vehicle V exists. First, in step S102, it is determined whether or not the vehicle V exists in the area E3. If it is determined that the vehicle V exists in the area E3, the entrance / exit light-emitting device 30 is caused to emit light in step S103, and the process returns to step S101. On the other hand, when it determines with the vehicle V not existing in the area E3 in step S102, it progresses to step S104. In step S104, it is determined whether or not the vehicle V exists in the area E2. If it is determined in step S104 that the vehicle V is present in the area E2, the process proceeds to step S105, and it is determined in which of the areas EL, EM, and ER the vehicle V is present. . That is, the approach direction of the vehicle V is specified. Thus, after the approach direction of the vehicle V is specified, it progresses to step S106. In step S106, one of the preset injection patterns to the front of the garage 11 is selected based on the determination result of step S105, and the laser beam is emitted toward the front of the garage 11 (outdoor horizontal direction L2). . Thereafter, the process returns to step S101.

  If it is determined in step S104 that the vehicle V does not exist in the area E2, that is, if it is determined that the vehicle V exists in the area E1, the process proceeds to step S103, and the entrance / exit light-emitting device 30 is caused to emit light. Thereafter, the process returns to step S101.

  Hereinafter, the operation of the parking position guidance system based on the vehicle position detection result will be described with reference to FIG. FIG. 5 is an operation explanatory diagram showing the relationship between the vehicle position and the parking guidance. For example, guidance is performed in the order of (a) → (b) → (c) at the time of warehousing.

  When the vehicle V approaches the garage 11, position detection by the vehicle position detection device 60 is performed when the vehicle V enters the detection area (for example, the third area E3). Specifically, first, based on the detection result, the control device 70 determines the distance between the vehicle V and the garage 11, that is, whether the vehicle V is located in the first area E1, the second area, or the third area. Is determined. As shown in FIG. 5A, when it is determined that the vehicle V is located in the third area E3, the light source devices 40L and 40R emit laser light toward the entrance / exit light-emitting device 30 side, that is, directly upward. To be driven. As a result, the entrance / exit light-emitting device 30 is turned on, and the periphery of the vehicle entrance / exit 13 is brightly illuminated. Therefore, the driver can easily grasp the vehicle entrance 13 to which the vehicle V should go.

  In the state where the vehicle V is moved toward the vehicle entrance 13 and enters the second area E2 as shown in FIG. 5B, the parking guidance mode is based on the detection result of the vehicle position detection device 60. Be changed. Specifically, the light source devices 40 </ b> L and 40 </ b> R are driven so that laser light is emitted toward the front of the garage 11. In such a case, it is also determined whether the vehicle V is located in the right area ER, the central area EM, or the left area EL. For example, as shown in FIG. 5C, when it is determined that the vehicle V is located in the left area EL, the laser beam is emitted in the predetermined direction described above (specifically, the diagonally left front direction of the vehicle entrance 13). The light source devices 40L and 40R are driven so that Thereby, the guide route to the garage 11 is shown by the laser light. By moving the vehicle V along this laser beam, the vehicle V is guided to the vehicle entrance 13. The laser beams are emitted so as to be parallel to each other. When the vehicle V is moved so as to be within the range sandwiched between these laser beams, the vehicle V is guided more suitably toward the garage 11.

  In a state where the vehicle V further moves and approaches the garage 11, that is, a state where the vehicle V enters the first area E1, the mode of parking guidance is changed based on the detection result of the vehicle position detection device 60. Specifically, the light source devices 40L and 40R are driven, and the laser light is adjusted to be emitted toward the entrance / exit light emitting device 30 side. As a result, the entrance / exit light-emitting device 30 is turned on, and the vehicle entrance / exit 13 is brightly illuminated. Thus, by visually illuminating the boundary of the vehicle entrance / exit 13, the vehicle entrance / exit 13 can be easily viewed. That is, it becomes easy to grasp the distance (gap) between the vehicle V and the vehicle doorway 13. Thereby, it is possible to make it difficult for the vehicle V to come into contact with the vehicle entrance 13.

  According to the embodiment described in detail above, the following excellent effects are obtained.

  When the vehicle approaches the garage 11 by the entrance light emitting device 30 provided at the edge of the vehicle entrance 13, the periphery of the vehicle entrance 13 is lit. Thereby, grasping | ascertaining the direction (namely, garage 11) which should go is easy. In particular, the left and right edges of the vehicle entrance / exit 13 are lit to facilitate the grasp of the width of the vehicle entrance / exit 13. At night or the like, the vehicle entrance / exit 13 is lit in this manner, so that the boundary between the garage 11 and the outer wall surface 12 can be easily determined. For this reason, the inconvenience that a vehicle and the vehicle entrance / exit 13 contact is suppressed suitably.

  Further, when the vehicle heads for the garage, a parking route (guideline) is indicated by the laser light from the light source devices 40L and 40R. By moving the vehicle along the laser beam, the vehicle is easily guided to a predetermined parking position. Thus, parking can be made easier by showing a parking route. In particular, in the present embodiment, the laser light is emitted in parallel from the two light sources, and when operating the vehicle so as to fall between the laser light from the left and right light source devices 40L and 40R, the route The error can be further reduced.

  It is assumed that the driver's attention is likely to concentrate on the vehicle entrance 13 of the garage 11 because the target to be headed is likely to be limited to the vehicle entrance 13 when normal parking is performed. In this regard, if the direction to be directed by the laser beam can be grasped as described above, the driver's attention can be directed not only to the vehicle entrance 13 but also to the laser beam side, that is, the left and right sides of the vehicle. As a result, the driver's line of sight can be directed to a wider range, which can contribute to ensuring safety during parking.

  As described above, the parking guidance by the laser beam is secured not only in the front of the garage 11 but also in the case of approaching from either the left or right direction. Furthermore, when parking is attempted from the diagonally front with respect to the vehicle entrance / exit 13, the degree of freedom of the approach route is considered to be smaller than parking from the front side. In the present embodiment, the width of the guide path formed by the two laser beams is configured to be small when it swings in the left-right direction. That is, the width of the guide route is also changed according to the degree of freedom of the approach route. Therefore, the response | compatibility according to the approach route of a vehicle is possible.

  Based on the detection information of the vehicle position detection device 60, the control device 70 determines the degree of approach of the vehicle (that is, the position of the vehicle). Since the guidance mode can be changed according to the position of the vehicle thus determined, parking guidance suitable for the situation can be provided in a series of flows during parking. Thereby, parking assistance can be made more suitable. Particularly in the present embodiment, a plurality of light guiding modes are realized by using the same light source. Thereby, the said effect can be show | played, suppressing complication of a structure.

  Moreover, according to this Embodiment, the vehicle position detection apparatus 60 can contribute to the improvement of the safety at the time of vehicle leaving. Specifically, even when some presence (for example, an obstacle such as another vehicle or a person) is detected in front of the garage 11 at the time of delivery, the light emission at the peripheral portion of the vehicle entrance 13 or the front of the garage 11 is detected. A laser beam is emitted to the laser beam. In such a case, the driver can grasp that there is a possibility that an obstacle exists outside the garage 11. Thus, by detecting an obstacle and emitting light, it is easy to call attention to the front space of the garage 11 at the time of leaving, which can contribute to improvement of safety.

  Further, laser light is used as a light source, and the laser light passes through the light transmitting member 39 so that the entrance / exit light-emitting device 30 emits light in almost the entire area. Thereby, light emission in a wide range is possible while suppressing an increase in the number of light sources.

(Another example in the first embodiment)
In the above embodiment, the laser light emission directions of the left and right light source devices 40L and 40R are the same, but the laser light emission directions of the light source devices 40L and 40R may be set separately and independently. . For example, as shown in FIG. 6A, in a state where the vehicle V is present in the second area E2, the light source device 40L emits laser light toward the outdoor horizontal direction, and the light source device 40R is an entrance / exit light-emitting device. A configuration in which laser light is emitted toward 30 may be adopted. Thereby, a guidance route can be shown, with the vehicle entrance 13 lighted. In this example, the guidance route is displayed by the light source device 40 on the vehicle approach direction side. Thereby, a guidance route can be shown on the inner ring side of the vehicle V. Usually, it is assumed that the driver's line of sight (attention) tends to face toward the center of rotation of the vehicle V. For this reason, if the guidance route is shown on the inner wheel side, the vehicle V can be guided more suitably than the case where the guidance route is shown on the outer wheel side.

  In the above embodiment, the laser beams in the light source devices 40L and 40R are configured to be parallel to each other when emitted in the outdoor horizontal direction, but this may be changed as follows. That is, as shown in FIG. 6B, the laser light from the light source devices 40 </ b> L and 40 </ b> R may intersect in front of the garage 11. Specifically, the intersection CP of these laser beams may be arranged on an ideal guiding path that is set in advance. In particular, by arranging the laser beam intersection CP on the ideal parking line, it is possible to more clearly indicate the course on which the vehicle V should travel.

  In the above embodiment, the light source device 40 is configured to irradiate laser light toward the outdoor horizontal direction (the front space of the garage 11), but this is changed in addition to the outdoor horizontal direction of the garage 11, It is also possible to adopt a configuration in which laser light irradiation is performed by the light source device 40 toward the indoor horizontal direction (a parking space in the garage 11).

  Specifically, in a state where the vehicle V is present in the first area E1, the laser light from the light source devices 40L and 40R may be emitted horizontally and inward of the garage 11. In such a case, it is desirable to cross the laser beams at a target parking position TP as shown in FIG. Thereby, an ideal parking position can be specified clearly. Usually, when the vehicle V exists in the 1st area E1, it is assumed that the inside of a garage is in a visible state. As described above, if the parking position is guided even inside the garage 11, guidance to an appropriate parking position can be made more suitable. In addition, it is also possible to cross | intersect the laser beam irradiated toward the indoor horizontal direction on the wall surface (for example, back wall) in a garage.

  In the above embodiment, the reflector 37 is disposed at the boundary portion between the right vertical light emitting portion 32R and the horizontal light emitting portion 34, but can also be disposed at the boundary portion between the left vertical light emitting portion 32L and the horizontal light emitting portion 34. It is. It is also possible to place them at both boundary portions.

(Second Embodiment)
In the present embodiment, the configuration relating to the light source device and the configuration associated therewith are different from those in the first embodiment. Therefore, these differences will be described in detail below with reference to FIGS. FIG. 7 is a schematic diagram showing a schematic configuration of a garage part of a house, which is a building with a garage in the present embodiment, and its surroundings, and FIG. is there. In addition, since the structure regarding the house 10 grade | etc., Is the same as that of 1st Embodiment, description is abbreviate | omitted.

  As shown in FIG. 7, in the present embodiment, a reflecting plate 100 that reflects light is provided at a connection portion with the vertical light emitting unit 32 at both ends of the horizontal light emitting unit 34 of the light transmitting member 31. Like the reflection plate 37, the reflection plate 100 is arranged so that the reflection surface intersects both the longitudinal direction of the vertical light emitting unit 32 and the longitudinal direction of the horizontal light emitting unit 34.

  A light source device 40R that emits laser light is disposed between the lower end portion of the right vertical light emitting portion 32R and the floor surface, and a light incident port 35 is provided at the lower end portion of the right vertical light emitting portion 32R. ing. On the other hand, instead of the light source device 40L, a light reflecting device 102 that reflects light in a predetermined direction is provided between the lower end of the left vertical light emitting unit 32L and the floor surface, and the left vertical light emitting unit 32L. A light exit port 101 is formed at the lower end of the. The laser light emitted from the light source device 40R enters the right vertical light emitting unit 32R through the light incident port 35, and passes through the right vertical light emitting unit 32R. Thus, the laser light that has passed through the right vertical light emitting unit 32R is reflected by the right reflector 100 and guided to the horizontal light emitting unit 34. The laser light that has passed through the horizontal light emitting unit 34 is reflected again by the left reflector 100 and guided to the left vertical light emitting unit 32L. Then, the light that has passed through the left vertical light emitting unit 32 </ b> L is emitted from the light transmission member 31 through the light emission port 101. The light reflecting device 102 is disposed on the path of the laser light emitted from the light emission port 101, and is configured to reflect the laser light toward the outdoor horizontal direction.

  The light reflecting device 102 includes an attachment portion 103 for the recess 21. One end of the mounting portion 103 is provided with a main body portion 105 having a reflection plate 104 in the internal space. The main body 105 is formed of a light transmitting member that transmits light. For this reason, light entering the reflecting plate 104 through the main body 105 and light exiting the light reflected by the reflecting plate 104 are allowed. The reflector 104 is disposed inside the main body 105 in an inclined state with respect to the traveling direction of the laser beam. Specifically, it is arranged so that the reflecting surface intersects both the front-rear direction and the up-down direction (in this embodiment, the angle formed between the traveling direction of the laser beam and the reflecting surface is inclined to about 45 °). . The reflecting plate 104 is rotatable inside the main body 105 about an axis extending in the same direction as the laser beam emitted from the light exit port 101 (that is, the vertical direction). As the reflecting plate 104 rotates, the laser beam reflected by the reflecting plate 104 is emitted in a predetermined direction in front of the garage 11. That is, by adjusting the rotation angle of the reflecting plate 104, the laser light emission direction can be changed. Further, in the present embodiment, the emission direction of the laser light of the light source device 40 is fixed toward the entrance / exit light emitting device 30 (specifically, the light entrance 35). That is, the light source device 40 does not require a configuration for changing the emission direction of the laser light. Therefore, it is possible to change the light source device 40 and provide only the laser light source. The reflector 104 is rotated by driving means such as an actuator, but detailed description of these actuators and the like is omitted.

  As shown in FIG. 8, in a state where the vehicle V is present in the third area E3 to the first area E1, the laser light from the reflector 104 is emitted toward the front of the garage 11 and is directed to the garage 11. A guidance path is shown. In such a case, since the laser light from the light source device 40 passes through the entrance / exit light-emitting device 30, guidance of the vehicle entrance / exit 13 by light emission from the entrance / exit light-emitting device 30 is also performed at the same time. Thus, a control process can be simplified by setting it as the structure which does not change the display mode for every area E1-E3.

  As shown in FIG. 8, the guidance of the vehicle entrance / exit 13 by the entrance / exit light-emitting device 30 and the display of the guide route by the laser light from the reflector 104 are performed at the same time, so that the guidance to the garage 11 at the time of parking is more preferable. It can be carried out.

(Another example in the second embodiment)
In the configuration shown in FIG. 7, the light source device 40 is provided on the right side and the light reflecting device 102 is provided on the left side with the vehicle entrance 13 interposed therebetween, but both of them may be interchanged. In other words, the laser beam is emitted from the lower left end portion of the vehicle entrance / exit 13 toward the outdoor horizontal direction, but the laser beam is emitted from the lower end portion of the right side of the vehicle entrance / exit 13 toward the outdoor horizontal direction. It is good.

  In the present embodiment, the light source device 40 is provided on one of the left and right sides of the vehicle entrance / exit 13, and the light reflecting device 102 is provided on the other side. However, this can be changed as follows. That is, it is possible to provide both the light source device 40 and the light reflecting device 102 on the left and right sides of the vehicle entrance 13. In such a case, the laser light emitted from the left light source device 40L can be guided to the right light reflection device 102, and the laser light emitted from the right light source device 40R can be guided to the left light reflection device 102. For example, the light source devices 40L and 40R to be driven may be switched according to the approach direction of the vehicle to the detection area defined by the vehicle position detection device 60. More specifically, laser beam irradiation in the horizontal direction on the inner ring side of the vehicle may be performed.

(Other examples)
As a condition for driving the light source device 40 and the light reflecting device 102 (that is, performing laser light irradiation), in addition to detecting the presence of the vehicle by the vehicle position detecting device 60, the outdoor brightness is below a predetermined level. It is good also as a structure which determines that it has become. Specifically, a detection device for detecting outdoor brightness is separately provided, and the light source device 40 and the light reflection device 102 are driven only when the detection device determines that the brightness is below a predetermined level. What is necessary is just to make it the structure made to do.

  Further, it is possible to drive the light source device 40 and the like only during a preset time period. For example, it may be configured such that driving of the light source device 40 is permitted in a time zone in which the periphery of a building is dark.

  In each of the above embodiments, the laser beam is irradiated in the outdoor horizontal direction only when the vehicle enters the vehicle. However, this is changed, and the laser beam is irradiated in the outdoor horizontal direction at the time of entry and also at the time of delivery. It is good also as composition which performs. Specifically, it is preferable to provide a calculation means for calculating an expected course in conjunction with each steering operation, and to irradiate a laser beam indicating the guidance path toward the expected course. Thereby, it can alert | report to the periphery that the vehicle is leaving or is going to leave. As a result, it can contribute to ensuring safety at the time of delivery.

  In each of the above embodiments, the vehicle approach is detected by the vehicle position detection device 60 having a non-contact sensor. However, the approach of the vehicle can be changed by installing a communication function device with the vehicle. You may know. For example, it is good to cooperate with the parking assist function (for example, IPA) which a vehicle has.

  The detection area by the vehicle position detection device 60 (that is, the boundary of the detectable area) may be set to coincide with the site of the house 10. For example, the outer edge or the like of the third area E3 may be matched with the boundary of the site of the house 10. Thereby, it is possible to detect a specific vehicle coming to the house 10, that is, a vehicle related to the house 10, while suppressing detection of a vehicle or the like not related to the house 10. Thereby, the guidance of the vehicle by a parking position guidance system can be implemented focusing on a specific vehicle, and irradiation of an unnecessary laser beam can be suppressed. It is also possible to set the outer edges of the areas E1 and E2 so as to coincide with the boundary of the site of the house 10.

  -You may provide the recognition means which recognizes vehicle information. When a vehicle approaches the house 10 (specifically, the garage 11), the light emission of the entrance light emitting device 30 or the like is performed on the condition that the recognition unit recognizes that the vehicle is a specific vehicle registered in advance. It is good also as composition which performs. For example, a transmitter that transmits vehicle information may be provided on the vehicle side, and a receiver that receives a signal from the transmitter may be provided on the house side.

  -You may provide the sensor which detects the presence of the vehicle in a garage. In this case, when it is determined that the vehicle exists in the garage, the light emission of the light source device 40 and the like may be stopped.

  In each of the embodiments described above, guidance is provided by laser light emitted in the outdoor horizontal direction and light emission around the vehicle entrance / exit 13 regardless of whether the vehicle is parked forward or rearward. However, the light emission guidance may be performed only when the vehicle is parked rearward. Specifically, a back signal receiving device that receives the back signal of the vehicle may be provided in the house 10 and the light emission guidance may be allowed only when the back signal receiving device detects the backward movement of the vehicle.

  The laser light emitted from the light source device 40 may be switched between a plurality of colors. For example, it may be possible to switch between the normal color and the warning color. A sensor or the like for detecting a gap (distance) between the vehicle entrance / exit 13 of the garage 11 and the vehicle V is individually provided, and the risk of contact between the vehicle entrance / exit 13 and the vehicle V is recognized by the sensor or the like. It may be notified that the possibility of contact with the vehicle doorway 13 or the like is high by switching to a warning color based on the above condition.

  In the case where the approach of the vehicle to the garage 11 is detected by the vehicle position detection device 60, a notification unit that notifies the approach of the vehicle inside the house 10 may be provided. Further, an entry sensor or the like for detecting that a vehicle has entered the garage 11 may be provided, and when the entry is detected by the entry sensor, the notification means may notify that the vehicle has entered.

  In each of the above embodiments, the parking position guidance system is applied to the attached garage 11 integrated with the house 10, but may be applied to a garage provided separately from the house. Moreover, unlike a garage, it is also possible to adapt to a parking lot that does not have a roof part or a surrounding wall part.
