Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, when the destination of a vehicle is a predetermined store, the vehicle traveling on the road crosses the sidewalk and enters the store from the road. At this time, a target person such as a pedestrian on the sidewalk or a driver riding a bicycle can predict that the vehicle will enter the store across the sidewalk from the road by confirming the lighting of the vehicle's turn signal.

[0005] However, when there are a plurality of store candidates, it becomes difficult for a target person on the sidewalk to predict which store among the plurality of stores the vehicle will enter. Therefore, when a plurality of stores are arranged side by side, even if the vehicle turns on the turn signal, there may be a risk of contact between the vehicle and the target person on the sidewalk.

[0006] In view of such problems, an object of the present invention is to provide a light-emitting notification system capable of reducing the contact risk between a vehicle and a target person on a sidewalk.

[0010] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in such embodiments are merely examples for facilitating the understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals to omit redundant description, and elements not directly related to the present invention are not shown.

[0011] FIG. 1 is a schematic configuration diagram showing the configuration of the light emission notification system 100 according to the present embodiment. As shown in FIG. 1, the light emission notification system 100 includes a light emitting device 200 and a vehicle 300. In the example shown in FIG. 1, a sidewalk 130 is provided between a plurality of stores 110 and a roadway 120. The roadway 120 is a road for the vehicle 300 to travel, which is demarcated by an outer lane line 120a of the roadway. The sidewalk 130 is a road for pedestrians to walk, which is demarcated by a road boundary line 130a and the outer lane line 120a of the roadway. Here, the sidewalk 130 includes a bicycle lane and the like, and in addition to pedestrians walking, bicycles can also travel. FIG. 1 shows an example in which the target person 140, who is a pedestrian or a driver riding a bicycle, is moving on the sidewalk 130.

[0012] The plurality of stores 110 includes a first store 110A and a second store 110B. The first store 110A and the second store 110B are provided adjacent to each other along the sidewalk 130. In the example shown in FIG. 1, when viewed from the extending direction of the roadway 120 and the sidewalk 130, the first store 110A and the second store 110B are located between the subject 140 and the vehicle 300. The first store 110A is located on the vehicle 300 side with respect to the second store 110B. The second store 110B is located on the subject 140 side with respect to the first store 110A. In the present embodiment, an example in which the plurality of stores 110 are two stores, the first store 110A and the second store 110B, will be described. However, the present invention is not limited to this, and the plurality of stores 110 may be three or more stores.

[0013] The vehicle 300 traveling on the roadway 120 can enter a parking lot (not shown) provided in each store 110. For example, the vehicle 300 traveling on the roadway 120 can enter a parking lot provided in a predetermined first store 110A across the sidewalk 130.

[0014] The light-emitting device 200 is provided on the sidewalk 130 located between each store 110 and the roadway 120. One light-emitting device 200 is provided for each store 110. That is, one light-emitting device 200 is provided for one store 110. In the present embodiment, one light-emitting device 200 is provided for the first store 110A. Also, one light-emitting device 200 is provided for the second store 110B. In the present embodiment, an example in which one light-emitting device 200 is provided for one store 110 will be described, but the present invention is not limited to this, and if the light-emitting device 200 can identify one store 110, a plurality of light-emitting devices 200 may be provided for one store 110.

[0015] FIG. 2 is a block diagram showing an example of the configuration of a light-emitting device 200 according to the present embodiment. The light-emitting device 200 includes a light-emitting body 210, a light-emitting control device 220, and a light-emitting side communication device 230. The light-emitting body 210 is an object that emits light, and is, for example, a lamp, a light bulb, a fluorescent lamp, a light-emitting diode, or the like. The light-emitting device 200 is embedded in, for example, a sidewalk 130 so as not to interfere with the movement of the vehicle 300 and the target person 140. However, the present invention is not limited to this, and the light-emitting device 200 may be provided, for example, on the front surface or a signboard of a store 110 so as not to interfere with the movement of the vehicle 300 and the target person 140. The light-emitting body 210 lights up by receiving a control command from the light-emitting control device 220. Note that the light-emitting body 210 turns off while not receiving a control command from the light-emitting control device 220.

[0016] The light-emitting body 210 lights up in a predetermined color. In the present embodiment, the light-emitting body 210 lights up in red. However, the present invention is not limited to this, and the light-emitting body 210 may emit light in a color other than red. Further, in the present embodiment, the light-emitting device 200 blinks the light-emitting body 210. However, the present invention is not limited to this, and the light-emitting device 200 may not blink the light-emitting body 210.

[0017] The light-emitting control device 220 controls the lighting of the light-emitting body 210. The light-emitting control device 220 includes an I / F 221, a data holding device 222, a system bus 223, one or more processors 224, and one or more memories 225. The I / F 221 is an interface for exchanging data with the light-emitting side communication device 230 and the light-emitting body 210. For example, the I / F 221 acquires data transmitted from the vehicle 300 via the light-emitting side communication device 230.

[0018] The data holding device 222 is composed of a RAM, a flash memory, an HDD, etc., and holds various information necessary for the processing of the following processor 224. In the present embodiment, store identification information for identifying the store 110 is stored in the data holding device 222.

[0019] Here, the store identification information is, for example, a store ID. The store ID is a unique identifier assigned to each store 110 and is used to individually identify each store 110. One store identification information is assigned to one store 110. For example, the first store identification information is assigned to the first store 110A, and the second store identification information is assigned to the second store 110B.

[0020] Also, one light-emitting device 200 is associated with one store 110. The store identification information of the associated store 110 is stored in the data holding device 222 of the light-emitting device 200. For example, the first store identification information assigned to the first store 110A is stored in the data holding device 222 of the light-emitting device 200 associated with the first store 110A. Also, the second store identification information assigned to the second store 110B is stored in the data holding device 222 of the light-emitting device 200 associated with the second store 110B.

[0021] However, it is not limited to this, and the store identification information may be the position information of the latitude and longitude of each store 110, or the position information of the address of each store 110. In this way, the data holding device 222 of the light-emitting device 200 functions as a storage device that stores the store identification information for identifying the store 110. The system bus 223 is a transmission path that electrically connects the I / F 221, the data holding device 222, the processor 224, and the memory 225 and transmits data between them.

[0022] The processor 224 includes, for example, a CPU (Central Processing Unit). The memory 225 includes, for example, a ROM (Read Only Memory) and a RAM (Random Access Memory). The ROM is a storage element that stores programs and calculation parameters used by the CPU. The RAM is a storage element that temporarily stores data such as variables and parameters used in the processing executed by the CPU.

[0023] The light-emitting side communication device 230 communicates with the vehicle side communication device 330 described later. Specifically, the light-emitting side communication device 230 receives the data transmitted from the vehicle side communication device 330 of the vehicle 300 and transmits the received data to the I / F 221. Also, the light-emitting side communication device 230 receives the data transmitted from the I / F 221 and transmits the received data to the vehicle 300.

[0024] FIG. 3 is a block diagram showing an example of the functional configuration of the light emission control device 220 according to the present embodiment. For example, as shown in FIG. 3, the light emission control device 220 includes a communication control unit 220a, a determination control unit 220b, and a light emission control unit 220c.

[0025] The processor 224 shown in FIG. 2 cooperates with the program included in the memory 225 and executes the program included in the memory 225, thereby realizing various processes including the processes described below performed by the communication control unit 220a, the determination control unit 220b, and the light emission control unit 220c.

[0026] The communication control unit 220a receives a signal including the destination information and the current position information of the vehicle 300 from the vehicle side communication device 330. The determination control unit 220b determines whether or not the destination information received by the communication control unit 220a matches the store identification information stored in the data holding device 222. The light emission control unit 220c controls the light emission of the light emitter 210 based on the determination result of the determination control unit 220b. Details of the processing of the communication control unit 220a, the determination control unit 220b, and the light emission control unit 220c will be described later.

[0027] FIG. 4 is a block diagram showing an example of the configuration of the vehicle 300 according to the present embodiment. The vehicle 300 includes a blinker 310, a vehicle control device 320, a vehicle side communication device 330, a position acquisition device 340, and a storage device 350.

[0028] The blinker 310 is a direction indicator for communicating the traveling direction of the vehicle 300 to following vehicles and the surroundings. The blinker 310 lights up by receiving a control command from the vehicle control device 320. Also, the blinker 310 turns off while not receiving a control command from the vehicle control device 320. Specifically, a driver boarding the vehicle 300 can operate an operation device (not shown) provided in the vehicle 300, and the vehicle control device 320 detects the operation of the operation device. When the vehicle control device 320 detects the operation of the operation device, it determines that the driver has performed an operation to emit light of the blinker 310, transmits a control command to the blinker 310, and executes lighting control to turn on the blinker 310.

[0029] The vehicle control device 320 controls the entire vehicle 300. The vehicle control device 320 includes an I / F 321, a data holding device 322, a system bus 323, one or more processors 324, and one or more memories 325. The I / F 321 is an interface for exchanging data with the vehicle-side communication device 330, the blinker 310, the position acquisition device 340, and the storage device 350. For example, the I / F 321 transmits data to the light-emitting device 200 via the vehicle-side communication device 330.

[0030] The data holding device 322 is composed of a RAM, a flash memory, an HDD, etc., and holds various information necessary for the processing of the processor 324 shown below. The system bus 323 is a transmission path that electrically connects the I / F 321, the data holding device 322, the processor 324, and the memory 325 and transmits data between them.

[0031] The processor 324 includes, for example, a CPU. The memory 325 includes, for example, a ROM and a RAM. The ROM is a storage element that stores programs and arithmetic parameters used by the CPU. The RAM is a storage element that temporarily stores data such as variables and parameters used for processing executed by the CPU.

[0032] The vehicle - side communication device 330 communicates with the light - emitting - side communication device 230. Specifically, the vehicle - side communication device 330 receives the data transmitted from the I / F 321 and transmits the received data to the light - emitting - side communication device 230. Also, the vehicle - side communication device 330 receives the data transmitted from the light - emitting - side communication device 230 and transmits the received data to the I / F 321.

[0033] FIG. 5 is a block diagram showing an example of the functional configuration of the vehicle control device 320 according to the present embodiment. For example, as shown in FIG. 5, the vehicle control device 320 includes a storage control unit 320a, an acquisition control unit 320b, a communication control unit 320c, and a lighting control unit 320d.

[0034] The processor 324 shown in FIG. 4 cooperates with the program included in the memory 325 and executes the program included in the memory 325 to realize various processes including the processes described below performed by the above - mentioned storage control unit 320a, acquisition control unit 320b, communication control unit 320c, and lighting control unit 320d.

[0035] The storage control unit 320a performs control to store the destination information regarding the destination of the vehicle 300 in the storage device 350. The acquisition control unit 320b performs control to acquire the current position information regarding the current position of the vehicle 300. The communication control unit 320c performs control to transmit a signal including the destination information and the current position information to the light - emitting - side communication device 230. The lighting control unit 320d performs control to turn on the blinker 310 when a light - emitting operation of the blinker 310 by the driver is detected. Details of the processes of the storage control unit 320a, acquisition control unit 320b, communication control unit 320c, and lighting control unit 320d will be described later.

[0036] The vehicle 300 is provided with a car navigation device (not shown) having a function of guiding the current position of the vehicle 300 and the route to the destination, and the position acquisition device 340 and the storage device 350 are included in this car navigation device.

[0037] The position acquisition device 340 acquires position information regarding the position of the vehicle 300. The position acquisition device 340 is, for example, a GPS (Global Positioning System). Specifically, the position acquisition device 340 acquires position information of latitude and longitude indicating the current position of the vehicle 300.

[0038] The storage device 350 stores destination information regarding the destination of the vehicle 300. For example, the driver operates a car navigation device mounted on the vehicle 300 to set the destination of the vehicle 300. The storage device 350 stores destination information indicating the position of the destination set by the driver.

[0039] The destination information includes, for example, position information of latitude and longitude of the first store 110A which is the destination of the vehicle 300, and store identification information for identifying the first store 110A which is the destination of the vehicle 300. Note that the vehicle-side communication device 330 transmits a signal including such destination information regarding the destination of the vehicle 300 and position information regarding the position of the vehicle 300 to the light-emitting side communication device 230.

[0040] Incidentally, when the destination of the vehicle 300 is the predetermined first store 110A, the vehicle 300 traveling on the road 120 crosses the sidewalk 130 and passes from the road 120 to the first store 110A. At this time, the target person 140 such as a pedestrian on the sidewalk 130 or a driver riding a bicycle can predict that the vehicle 300 will enter the store 110 by crossing the sidewalk 130 from the road 120 by confirming the lighting of the blinker 310 of the vehicle 300.

[0041] However, when there are a plurality of candidates for the store 110, it becomes difficult for the target person 140 on the sidewalk 130 to predict which store 110 among the plurality of stores 110 the vehicle 300 will enter. Therefore, when a plurality of stores 110 are arranged adjacent to each other, even if the vehicle 300 turns on the blinker 310, there may be a risk of contact between the vehicle 300 and the target person 140 on the sidewalk 130.

[0042] Therefore, in the present embodiment, a light-emitting device 200 is provided on a sidewalk 130 located between each store 110 and a roadway 120. The light-emitting device 200 receives destination information and current position information from a vehicle 300 traveling on the roadway 120, and when the destination of the vehicle 300 corresponds to a predetermined store 110, it executes a process of causing a light-emitting body 210 to emit light according to the relative distance from the vehicle 300. Hereinafter, the processes in the light-emitting device 200 and the vehicle 300 of the present embodiment will be described in detail. Note that, hereinafter, an example in which the vehicle 300 is traveling on the roadway 120 with the first store 110A as the destination will be described. When the vehicle 300 has the second store 110B as the destination, the same process as when the vehicle 300 has the first store 110A as the destination is performed, and thus detailed description thereof will be omitted.

[0043] First, when the navigation device of the vehicle 300 is operated by the driver and the destination of the vehicle 300 is set, the storage control unit 320a stores destination information regarding the destination of the vehicle 300 in the storage device 350. In the present embodiment, the destination information includes first store identification information assigned to the first store 110A.

[0044] Also, the acquisition control unit 320b acquires current position information regarding the current position of the vehicle 300 from the position acquisition device 340. Then, the communication control unit 320c calculates the relative distance between the vehicle 300 and the first store 110A based on the destination information and the current position information. For example, the communication control unit 320c calculates the relative distance between the vehicle 300 and the first store 110A from the latitude and longitude of the first store 110A and the latitude and longitude of the current position of the vehicle 300. Note that the relative distance between the vehicle 300 and the first store 110A is assumed to be equal to the relative distance between the vehicle 300 and the light-emitting device 200 associated with the first store 110A.

[0045] In addition, the communication control unit 320c determines whether or not a lighting operation of the blinker 310 by the driver is detected. When the lighting operation of the blinker 310 by the driver is detected, the lighting control unit 320d executes lighting control to turn on the blinker 310.

[0046] When the relative distance between the vehicle 300 and the first store 110A is less than a predetermined distance and the light emission operation of the blinker 310 is detected, the communication control unit 320c determines that a predetermined condition is satisfied. Here, the predetermined distance is, for example, 30 m. Then, when determining that the predetermined condition is satisfied, the communication control unit 320c transmits a signal including the destination information stored in the storage device 350 and the current position information of the vehicle 300 to the light emission side communication device 230.

[0047] The communication control unit 220a of the light emission device 200 receives a signal including the destination information and the current position information transmitted from the communication control unit 320c of the vehicle 300. The determination control unit 220b determines whether or not the store identification information stored in the data holding device 222 matches the store identification information included in the signal transmitted from the vehicle 300. In the present embodiment, it is assumed that the store identification information stored in the data holding device 222 and the store identification information included in the signal transmitted from the vehicle 300 are the first store identification information assigned to the first store 110A and they match.

[0048] When it is determined by the determination control unit 220b that they match, the light emission control unit 220c permits the light emission of the light emitter 210 and performs control to cause the light emitter 210 to emit light. On the other hand, when it is determined by the determination control unit 220b that they do not match, the light emission control unit 220c prohibits the light emission of the light emitter 210. In the present embodiment, the destination of the vehicle 300 is the first store 110A, and the light emission control unit 220c of the light emission device 200 associated with the first store 110A performs control to permit the light emission of the light emitter 210 when it is determined by the determination control unit 220b that they match. On the other hand, the light emission control unit 220c of the light emission device 200 associated with the second store 110B performs control to prohibit the light emission of the light emitter 210 when it is determined by the determination control unit 220b that they do not match. Thereby, when the vehicle 300 is located near a predetermined destination, the light emission device 200 associated with the predetermined destination performs control to permit light emission, and the light emission device 200 not associated with the predetermined destination performs control to prohibit light emission.

[0049] As described above, according to the present embodiment, the communication control unit 320c of the vehicle 300 calculates the relative distance between the vehicle 300 and the store 110 that is the destination based on the destination information and the current position information of the vehicle 300. Then, when the relative distance is less than a predetermined distance and the lighting operation of the blinker 310 is detected, the communication control unit 320c transmits a signal including the destination information and the current position information toward the light emitting device 200. Further, the light emission control unit 220c of the light emitting device 200 controls the light emitter 210 to emit light according to the destination information and the current position information transmitted from the vehicle 300. As a result, when the distance between the vehicle 300 and the store 110 that is the destination is less than the predetermined distance and the blinker 310 of the vehicle 300 is turned on, the light emitter 210 can be made to emit light in the light emitting device 200. As a result, the subject person 140 can easily grasp both the store 110 that the vehicle 300 is about to enter and the vehicle 300 that is about to enter the store 110 by visually observing the blinker 310 of the vehicle 300 and the light emission of the light emitting device 200.

[0050] Furthermore, according to the present embodiment, the determination control unit 220b of the light emitting device 200 determines whether or not the store identification information stored in the data holding device 222 matches the store identification information received from the vehicle 300. Then, when it is determined by the determination control unit 220b that they match, the light emission control unit 220c permits the light emitter 210 to emit light, and when it is determined that they do not match, the light emission control unit 220c prohibits the light emitter 210 from emitting light. As a result, only the light emitting device 200 linked to the store 110 that is the destination of the vehicle 300 can be made to emit light, and the light emitting device 200 linked to the store 110 that is not the destination of the vehicle 300 can be prevented from emitting light. As a result, the risk of contact between the vehicle 300 and the subject person 140 on the sidewalk 130 can be reduced.

[0051] As described above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings. Needless to say, the present invention is not limited to such embodiments. It is obvious that those skilled in the art can conceive of various modification examples or correction examples within the scope described in the claims, and it is naturally understood that those also belong to the technical scope of the present invention.

[0052] In the above embodiment, an example has been described in which the communication control unit 320c transmits a signal including destination information and current position information when the relative distance between the store 110, which is the destination of the vehicle 300, and the current position of the vehicle 300 is less than a predetermined distance. However, the present invention is not limited to this, and the communication control unit 320c may transmit a signal including destination information and current position information when the relative distance between the store 110, which is the destination of the vehicle 300, and the current position of the vehicle 300 is equal to or greater than a predetermined distance.

[0053] In the above embodiment, an example has been described in which the communication control unit 320c transmits a signal including destination information and current position information when a lighting operation of the turn signal 310 by the driver is detected. However, the present invention is not limited to this, and the communication control unit 320c may transmit a signal including destination information and current position information even when a lighting operation of the turn signal 310 by the driver is not detected. That is, regardless of whether or not the turn signal 310 is lit, the communication control unit 320c may transmit a signal including destination information and current position information if the relative distance between the store 110, which is the destination of the vehicle 300, and the current position of the vehicle 300 is less than a predetermined distance.

[0054] In this case, the communication control unit 320c of the vehicle 300 calculates the relative distance between the store 110, which is the destination, and the vehicle 300 based on the destination information and the current position information. Then, when the relative distance becomes less than a predetermined distance, the communication control unit 320c transmits a signal including destination information and current position information toward the light emitting device 200. Thereby, even when the driver forgets to operate the turn signal 310 and tries to enter the store 110, when the distance between the vehicle 300 and the store 110, which is the destination, is less than a predetermined distance, the light emitter 210 can be caused to emit light in the light emitting device 200. Therefore, the target person 140 can grasp that the vehicle 300 is about to enter the store 110 even when the turn signal 310 of the vehicle 300 is not lit.

[0055] In the above embodiment, an example has been described in which the communication control unit 320c of the vehicle 300 calculates the relative distance between the store 110 which is the destination of the vehicle 300 and the current position of the vehicle 300. However, the present invention is not limited to this, and the light emission control unit 220c of the light emitting device 200 may calculate the relative distance between the store 110 which is the destination of the vehicle 300 and the current position of the vehicle 300. Specifically, the communication control unit 320c of the vehicle 300 transmits a signal including the destination information and the current position information of the vehicle 300. The communication control unit 220a of the light emitting device 200 receives a signal including the destination information and the current position information from the vehicle 300. Then, the light emission control unit 220c calculates the relative distance between the store 110 which is the destination of the vehicle 300 and the current position of the vehicle 300 based on the received destination information and current position information. When the calculated relative distance is less than a predetermined distance, the light emission control unit 220c controls the light emitter 210 to emit light. Thereby, similar to the above embodiment in which the relative distance is calculated on the vehicle 300 side, the subject 140 on the sidewalk 130 can visually confirm which store 110 among the plurality of stores 110 the vehicle 300 is approaching. As a result, the risk of contact between the vehicle 300 and the subject 140 on the sidewalk 130 can be reduced. Further, the calculation of the relative distance between the destination and the current position on the vehicle 300 side can be omitted, and the processing load of the vehicle control device 320 can be reduced.

[0056] In the above embodiment, an example has been described in which the light emitter 210 of the light emitting device 200 blinks in red. However, the present invention is not limited to this, and the light emitting device 200 may rotationally drive the light emitter 210. For example, the light emitter 210 is constituted by a lamp, and the light emission control unit 220c of the light emitting device 200 may rotationally drive the lamp. Further, the light emitting device 200 may generate a sound in addition to the light emission of the light emitter 210. For example, the light emission control unit 220c of the light emitting device 200 may cause the light emitter 210 to emit light and cause a warning sound to be generated by a sound device (not shown). Thereby, the subject 140 can more easily recognize the store 110 into which the vehicle 300 is about to enter.

[0057] Further, the light emitter 210 may be part of a display device capable of displaying characters or symbols. In that case, the light emission control unit 220c of the light emitting device 200 may perform control to cause the light emitter 210 to emit light so as to display characters or symbols. For example, the light emission control unit 220c may cause the light emitter 210 to emit light so as to display a cautionary character to alert the entry of the vehicle 300 into the sidewalk 130. Further, the light emission control unit 220c may cause the light emitter 210 to emit light so as to display an arrow symbol indicating the route by which the vehicle 300 enters the store 110. Thereby, the target person 140 can more easily recognize the store 110 into which the vehicle 300 is about to enter.

[0058] Note that the series of processes by the light emission control device 220 and the vehicle control device 320 according to the above-described embodiment may be realized using any one of software, hardware, or a combination of software and hardware. The program constituting the software is stored in advance, for example, in a non-transitory storage medium provided inside or outside each device. Then, the program is read from a non-transitory storage medium (for example, ROM) into a temporary storage medium (for example, RAM) and executed by a processor such as a CPU.

[0059] It is possible to create a program for realizing each function of the above-described devices and install it in the computers of the above-described devices. When the processor executes the program stored in the memory, the processing of each of the above functions is executed. At this time, the program may be executed in a shared manner by a plurality of processors, or the program may be executed by one processor. Further, each function of the above-described devices may be realized by cloud computing using a plurality of computers interconnected by a communication network. Note that the program may be provided to and installed in the computers of each device by distribution from an external device through a communication network.
