According to the parking guide system 100 of the present embodiment, the laser light 20 including the line generator 212 is installed on the side wall 11b of the raised floor 10 that is separated from the parking space S and extends above the traffic area G. The line generator 212 irradiates the passing region G with the laser light 23 so as to trace the width regulation line WL of the parking space S, and forms the guide line 24 on the passing region G. Therefore, the parking guide system 100 does not process the traffic area G in which the vehicle is parked, and when the markings or obstacles such as the white line W of the parking space S are hard to see at night or the like, or are hidden by snow or the like. It can guide the parking of the vehicle in case of accident.

In the passage area G, a white line W is drawn at a position where the parking space S and the width regulation line WL overlap. The guide line 24 formed by the line generator 212 is formed so as to overlap the white line W. Therefore, the vehicle can be parked at the same position as during the daytime or in good weather.

The line generator 212 irradiates the side where the vehicle is parked with respect to the entrance regulation line AL with the laser light 23 to form the guide line 24. Therefore, the driver of the vehicle can visually recognize the entry regulation line AL as the end of the guide line 24, and the vehicle is prevented from exceeding the entry regulation line AL.

As described above, one embodiment of the present invention has been described in detail with reference to the drawings. However, the specific configuration is not limited to this embodiment, and a configuration change, a combination, etc. within a range not departing from the gist of the present invention are also possible. included.

For example, in the parking guide system, the guide line 24 may be formed by the laser light 20 installed on the support structure provided on the left side or the right side of the parking space S.

The laser light 20 may irradiate the passage area G with the laser light 23 so as to trace the entry restriction line AL of the parking space S, and form a guide line on the passage area G.

The length of the guide line in the depth direction may be shorter than the white line W or longer than the white line W.

The guide line has a high illuminance part where the illuminance is high for a place where the driver is required to pay particular attention, and a low illuminance part where the illuminance is low for a place where it is not necessary to draw the driver special attention. The line generator may be configured as follows.

FIG. 6 is a functional block diagram of a modified example of the parking guide system. As shown in FIG. 6, the parking guide system may include a distance measuring sensor 30 and a control unit 40. The parking guide system including the distance measuring sensor 30 controls the laser light 20 via the control unit 40.

FIG. 7 is a flowchart showing the operation of the parking guide system having the distance measuring sensor 30. As shown in FIG. 7, in step S1, the distance measuring sensor 30 measures the distance D between the vehicle and the parking space S and transmits information on the distance D to the control unit 40, and the control unit 40 keeps the distance D constant. It is determined whether the value is greater than or equal to the value. If the distance D is greater than or equal to a certain value, the distance measuring sensor 30 and the control unit 40 end the operation. If the distance D is less than the fixed value, the control unit 40 performs the process of step S2. In step S2, the control unit 40 causes the laser light 20 to emit the laser light 23. After performing the process of step S2, the control unit 40 returns to the process of step S1.

The parking guide system including the distance measuring sensor 30 stops the emission of the laser light 23 from the laser light 20 when the vehicle is not approaching the parking space S and there is no vehicle to park. Therefore, the parking guide system including the distance measuring sensor 30 can save power consumption and energy consumption.
