Embodiments for Carrying Out the Invention

[0015] Hereinafter, in the present disclosure, the drawings are associated with one or more embodiments. Also, in all the drawings, the same components are denoted by the same reference numerals, and the description thereof is omitted as appropriate.

[0016] As shown in Fig. 1, the power transmission control system includes a transmission device 10 and a power transmission control device 20, and is used together with a wireless power transmission device 30 and a wireless power reception device 42. The wireless power transmission device 30 is installed on a road, and the wireless power reception device 42 is mounted on a vehicle 40. The wireless power transmission device 30 and the wireless power reception device 42 supply power to the vehicle 40 while the vehicle 40 is traveling on the road. This power is stored, for example, in a secondary battery mounted on the vehicle 40. The vehicle 40 may be, for example, an electric vehicle or a hybrid vehicle.

[0017] The wireless power transmission device 30 is controlled by the power transmission control device 20. In the example shown in this figure, the power transmission control device 20 controls a plurality of wireless power transmission devices 30. The plurality of wireless power transmission devices 30 are controlled independently of each other. For example, the timing of the power supply operation of the plurality of wireless power transmission devices 30 is controlled independently of each other.

[0018] The transmission device 10 can be mounted on the vehicle 40 and is mounted on the vehicle 40 at least while the vehicle 40 is traveling. A part of the information necessary when the power transmission control device 20 controls the wireless power transmission device 30 is transmitted to the power transmission control device 20. The transmission device 10 may be a portable communication device or a communication device fixed to the vehicle 40. In the former case, the transmission device 10 may be a wireless communication device possessed by the user of the vehicle 40, such as a smartphone or a tablet terminal.

[0019] The position of the wireless power reception device 42 in the vehicle 40 may vary depending on the vehicle 40. Specifically, as shown by the solid line and the dotted line in Fig. 2, the position of the wireless power reception device 42 in the width direction of the vehicle 40 may vary depending on the vehicle 40. Also, as shown by the solid line and the dotted line in Fig. 3, the position of the wireless power reception device 42 in the front-rear direction of the vehicle 40 may also vary depending on the vehicle 40. When the positions of the wireless power reception devices 42 in the same vehicle model are the same, the positions of the wireless power reception devices 42 may vary depending on the vehicle model.

[0020] As shown in FIG. 4, the transmission device 10 includes a transmission unit 120. The transmission unit 120 transmits first position information to the power transmission control device 20. The first position information is information that can specify the position of the wireless power receiving device 42 within the vehicle 40.

[0021] As shown in FIG. 4, the transmission device 10 may further include a first detection unit 110. The first detection unit 110 detects that the relative position between the vehicle 40 and the wireless power transmission device 30 installed on the road on which the vehicle 40 is traveling satisfies a standard. In this case, when this relative position satisfies the standard, the transmission unit 120 transmits the first position information to the power transmission control device 20.

[0022] The first position information may indicate the position of the wireless power receiving device 42 in the width direction of the vehicle 40, may indicate the position of the wireless power receiving device 42 in the front-rear direction of the vehicle 40, or may indicate both of these. The first position information may indicate the distance from one end of the vehicle in the width direction, for example, the right end or the left end, to the center of the wireless power receiving device 42. The first position information may indicate the distance from one end of the vehicle in the front-rear direction, for example, the front end or the rear end, to the center of the wireless power receiving device 42.

[0023] The first position information may be information indicating the type of the vehicle 40. In this case, the control unit 220 uses the first position information and storage means that stores information indicating the position of the wireless power receiving device 42 in each vehicle type, that is, for each vehicle type, to specify the position of the wireless power receiving device 42 in the vehicle 40. This storage means may be possessed by the power transmission control device 20 or may be provided outside the power transmission control device 20.

[0024] As shown in FIG. 5, the power transmission control device 20 includes an acquisition unit 210 and a control unit 220. The acquisition unit 210 acquires the first position information from the vehicle 40. The control unit 220 controls the wireless power transmission device 30 using the first position information.

[0025] As a hardware configuration, the transmission device 10 has, for example, as shown in FIG. 6, a bus 1010, a processor 1020, a memory 1030, a storage device 1040, an input / output interface 1050, and a network interface 1060.

[0026] The bus 1010 is a data transmission path for the processor 1020, the memory 1030, the storage device 1040, the input / output interface 1050, and the network interface 1060 to transmit and receive data to and from each other. However, the method of connecting the processor 1020 and the like to each other is not limited to bus connection.

[0027] The processor 1020 is a processor realized by a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), or the like.

[0028] The memory 1030 is a main storage device realized by a RAM (Random Access Memory) or the like.

[0029] The storage device 1040 is an auxiliary storage device realized by an HDD (Hard Disk Drive), an SSD (Solid State Drive), a removable medium such as a memory card, or a ROM (Read Only Memory), and has a recording medium. The recording medium of the storage device 1040 stores program modules that realize each function of the transmission device 10 (for example, the first detection unit 110 and the transmission unit 120, and the vehicle position detection unit 130, the travel control unit 140, and the second detection unit 160 described later). By the processor 1020 loading and executing these program modules onto the memory 1030, each function corresponding to the program module is realized. Further, the storage device 1040 may function as a map information storage unit 150 described later.

[0030] The input / output interface 1050 is an interface for connecting the transmission device 10 and various input / output devices.

[0031] The network interface 1060 is an interface for connecting the transmission device 10 to a network. This network is, for example, a LAN (Local Area Network) or a WAN (Wide Area Network). The method by which the network interface 1060 connects to the network may be a wireless connection or a wired connection. The transmission device 10 may communicate with the power transmission control device 20 via the network interface 1060.

[0032] Note that the transmission device 10 may be realized by a plurality of devices each having the configuration shown in FIG. 6. Also, the example of the hardware configuration of the power transmission control device 20 is the same as the example of the hardware configuration of the transmission device 10.

[0033] The transmission device 10 and the power transmission control device 20 operate as shown in, for example, FIG. 7. The vehicle 40 is traveling on a road. At least one wireless power transmission device 30 is installed on the road. The first detection unit 110 of the transmission device 10 detects that the relative position between the vehicle 40 and the wireless power transmission device 30 installed on the road on which the vehicle 40 is traveling satisfies a reference (step S10). When this relative position satisfies the reference, the transmission unit 120 transmits the first position information to the power transmission control device 20 (step S20).

[0034] The acquisition unit 210 of the power transmission control device 20 acquires the first position information transmitted by the vehicle 40. Then, the control unit 220 of the power transmission control device 20 controls the wireless power transmission device 30 using the first position information (step S30). An example of this control is at least one of control of the timing to start the power supply operation of the wireless power transmission device 30 and control of the timing to end the power supply operation of the wireless power transmission device 30. When the control unit 220 controls a plurality of wireless power transmission devices 30, an example of this control also includes selecting the wireless power transmission device 30 that performs the power supply operation.

[0035] Note that when the transmission device 10 does not include the first detection unit 110, step S10 is omitted.

[0036] In this way, when the transmission device 10 and the power transmission control device 20 are used, the wireless power transmission device 30 is controlled according to the position of the wireless power reception device 42 in the vehicle 40. Therefore, it is possible to suppress a decrease in power transmission efficiency due to a deviation in the relative position between the wireless power transmission device 30 and the wireless power reception device 42.

[0037] For example, as shown in FIG. 8, when a plurality of wireless power transmission devices 30 are installed in the width direction of the road 50, the first position information indicates at least the position of the wireless power reception device 42 in the width direction of the vehicle 40. Then, the control unit 220 of the power transmission control device 20 causes the wireless power transmission device 30 corresponding to the first position information to perform a power supply operation. For example, the control unit 220 causes the wireless power transmission device 30 closest to the wireless power reception device 42 in the width direction of the road 50 to perform a power supply operation.

[0038] Also, as shown in FIG. 9, when a plurality of wireless power transmission devices 30 are installed in the front-rear direction of the road 50, the first position information indicates at least the position of the wireless power reception device 42 in the front-rear direction of the vehicle 40. Then, the control unit 220 of the power transmission control device 20 causes the wireless power transmission device 30 corresponding to the first position information to perform a power supply operation. For example, when the vehicle 40 is stopped, the control unit 220 causes the wireless power transmission device 30 closest to the wireless power reception device 42 in the front-rear direction of the road 50 to perform a power supply operation.

[0039] Also, as shown in FIG. 10, when a plurality of wireless power transmission devices 30 are installed in each of the width direction and the front-rear direction of the road 50, the first position information indicates at least the position of the wireless power reception device 42 in the width direction of the vehicle 40. Then, the control unit 220 causes the plurality of wireless power transmission devices 30 closest to the wireless power reception device 42 in the width direction of the road 50 to perform a power supply operation. The first position information preferably further indicates the position of the wireless power reception device 42 in the front-rear direction of the vehicle 40. In this case, when the vehicle 40 is stopped, the control unit 220 causes the wireless power transmission device 30 closest to the wireless power reception device 42 in the front-rear direction of the road 50 to perform a power supply operation.

[0040] Note that the wireless power transmission device 30 is installed, for example, before and after a gate installed at the boundary between an exclusive road for automobiles and a general road, before and after a traffic signal, and before and after an intersection, etc., at locations where the vehicle 40 decelerates or stops.

[0041] When supplying power to the vehicle 40, the transmission device 10 may transmit the identification information of the vehicle 40 to the power transmission control device 20. The identification information of the vehicle 40 is, for example, at least one of a registration number, i.e., the number on the license plate, a vehicle body number, and the number of a credit card for ETC (Electronic Toll Collection System). The identification information of the vehicle 40 is used, for example, when billing the user for the cost related to power supply.

[0042] As shown in FIG. 11, on the road 50, a signal transmission device 60 that wirelessly transmits signals, for example, a beacon, may be installed at a position in front of the wireless power transmission device 30 in the traveling direction of the vehicle 40. The distance from the signal transmission device 60 to the wireless power transmission device 30 in the front-rear direction of the road 50 is, for example, 10 m or more and 200 m or less, preferably 50 m or more and 150 m or less. This distance may be changed according to the legal speed of the road 50. For example, this distance on a road 50 with a high legal speed is larger than this distance on a road 50 with a low legal speed. The communicable distance of the signal transmission device 60 is, for example, 50 m or less. When the signal transmission device 60 is provided, the first detection unit 110 of the transmission device 10 detects that the relative position between the vehicle 40 and the wireless power transmission device 30 satisfies the standard by receiving a signal from the signal transmission device 60. In other words, when the first detection unit 110 receives a signal from the signal transmission device 60, it determines that this relative position satisfies the standard. By doing so, the first detection unit 110 can accurately detect that the relative position between the vehicle 40 and the wireless power transmission device 30 satisfies the standard. Then, the power transmission control device 20 acquires the first position information from the transmission device 10 and starts the power supply operation of the wireless power transmission device 30 corresponding to this first position information.

[0043] As shown in FIG. 12, in addition to the first detection unit 110 and the transmission unit 120, the transmission device 10 may further include a vehicle position detection unit 130 and a travel control unit 140. The transmission device 10 may also be able to utilize the information stored in the map information storage unit 150. The map information storage unit 150 stores map information. The map information storage unit 150 may be a part of the transmission device 10 or may be located outside the transmission device 10.

[0044] The vehicle position detection unit 130 detects the position of the vehicle 40 in the real space. For example, the vehicle position detection unit 130 generates latitude and longitude information indicating the position of the vehicle 40 using GPS information.

[0045] The map information stored in the map information storage unit 150 also includes information indicating the position where the wireless power transmission device 30 is installed among the roads 50, for example, latitude and longitude information. Here, the map information may include information indicating how a plurality of wireless power transmission devices 30 are installed in that location. The map information stored in the map information storage unit 150 is used, for example, in a navigation system for guiding the vehicle 40. Therefore, in addition to the above-described information, this map information includes various types of information necessary for guiding the vehicle 40. However, the map information storage unit 150 may be composed only of information indicating the position where the wireless power transmission device 30 is installed among the roads 50. In this case, map information used in the navigation system is prepared separately from the information stored in the map information storage unit 150.

[0046] Then, the first detection unit 110 uses the position of the vehicle 40 detected by the vehicle position detection unit 130 and the position of the wireless power transmission device 30 stored in the map information storage unit 150 to detect that the relative position between the vehicle 40 and the wireless power transmission device 30 satisfies the standard. An example of the standard used here is that the relative distance between the vehicle 40 and the wireless power transmission device 30 becomes equal to or less than the reference value. This reference value is selected from, for example, the range of 10 m or more and 100 m or less, but values outside this range may also be used. Further, this reference value may be changed according to the legal speed of the road 50. For example, the reference value for the road 50 with a higher legal speed is larger than the reference value for the road 50 with a lower legal speed.

[0047] Even in this way, the first detection unit 110 can accurately detect that the relative position between the vehicle 40 and the wireless power transmission device 30 satisfies the standard.

[0048] In addition, the acquisition unit 210 of the power transmission control device 20 may acquire second position information indicating the position of the vehicle 40 on the road 50. The control unit 220 further controls the wireless power transmission device 30 using the second position information. An example of the control performed here is as described with reference to FIGS. 9 and 10.

[0049] An example of the second position information is information generated by the vehicle position detection unit 130 of the transmission device 10, for example, latitude and longitude information. In this case, the transmission unit 120 of the transmission device 10 transmits the second position information generated by the vehicle position detection unit 130 to the power transmission control device 20. The acquisition unit 210 of the power transmission control device 20 acquires this second position information. Then, the control unit 220 of the power transmission control device 20 determines the start timing and the end timing of the power supply operation of the wireless power transmission device 30 so as to include a period in which at least a part of the wireless power reception device 42 overlaps at least a part of the wireless power transmission device 30 in the front-rear direction of the road 50.

[0050] For example, the transmission unit 120 repeatedly transmits the second position information generated by the vehicle position detection unit 130 to the power transmission control device 20. This transmission interval is, for example, 0.5 seconds or more and 30 seconds or less. Then, the control unit 220 starts the power supply operation of the wireless power transmission device 30 at the timing when the position indicated by the second position information reaches a predetermined distance in front of the wireless power transmission device 30. This predetermined distance is, for example, 5 m or more and 100 m or less, but is not limited thereto. Also, the control unit 220 ends the power supply operation of the wireless power transmission device 30 at the timing when the position indicated by the second position information reaches a predetermined distance behind the wireless power transmission device 30. This predetermined distance is, for example, 5 m or more and 100 m or less, but is not limited thereto.

[0051] Further, the transmission unit 120 may transmit the second position information generated by the vehicle position detection unit 130 and the speed information indicating the speed of the vehicle 40 to the power transmission control device 20. For example, the control unit 220 of the power transmission control device 20 calculates the distance from the vehicle 40 to the wireless power transmission device 30 using the second position information, and divides this distance by the speed indicated by the speed information to calculate the time until the vehicle 40 reaches the wireless power transmission device 30 from now, that is, the arrival time. The arrival time may be a time. Then, the control unit 220 specifies the start timing of the power supply operation of the wireless power transmission device 30 by subtracting a predetermined time from the arrival time. This predetermined time is, for example, 1 second or more and 5 seconds or less, but is not limited to these ranges. Also, the control unit 220 specifies the end timing of the power supply operation of the wireless power transmission device 30 by adding a predetermined time to the arrival time. This predetermined time is, for example, 1 second or more and 5 seconds or less, but is not limited to these ranges.

[0052] Also, when the vehicle 40 stops, the vehicle position detection unit 130 may cause the wireless power transmission device 30 closest to the wireless power reception device 42 in the front-rear direction of the road 50 to perform a power supply operation.

[0053] These controls may be performed simultaneously with, for example, the control described with reference to FIG. 8 or the control described with reference to FIG. 10.

[0054] Also, as shown in FIG. 13, when a sensor 70 for detecting the position of the vehicle 40 is provided on the road 50, the acquisition unit 210 may generate second position information using the information generated by the sensor 70. An example of the sensor 70 is an imaging device. In this case, the acquisition unit 210 generates the second position information by processing the image generated by the imaging device. Note that the sensor 70 is not limited to the imaging device. For example, the sensor 70 may be a sensor that generates second position information, such as a proximity sensor. The detection area by the sensor 70 is, for example, slightly in front of the area where the wireless power transmission device 30 is installed in the longitudinal direction of the road 50, and is at least a part of, for example, 10 m or more and 100 m or less from the area.

[0055] The second position information may include information indicating the position of the vehicle 40 in the width direction of the road 50. For example, when the sensor 70 is an imaging device, the acquisition unit 210 can include, in the second position information, information indicating the position of the vehicle 40 in the width direction of the road 50. Then, the control unit 220 selects the wireless power transmission device 30 to perform the power supply operation among the plurality of wireless power transmission devices 30 using the position of the vehicle 40 in the width direction of the road 50. For example, the control unit 220 specifies the position of the wireless power reception device 42 in the width direction of the road 50 using the first position information and the second position information. Then, the control unit 220 selects the wireless power transmission device 30 closest to the wireless power reception device 42 at this position and starts the power supply operation of the selected wireless power transmission device 30.

[0056] Using the second position information improves the power transmission efficiency from the wireless power transmission device 30 to the wireless power reception device 42.

[0057] The travel control unit 140 controls the travel of the vehicle 40. For example, the travel control unit 140 controls the travel route and speed of the vehicle 40 using the detection results of the sensors mounted on the vehicle 40 and the information stored in the map information storage unit 150.

[0058] Here, the travel control unit 140 may acquire third position information indicating the position on the road 50 where the wireless power transmission device 30 is provided, and control the travel on the road 50 using this third position information. For example, when the distance between the wireless power transmission device 30 and the vehicle 40 approaches, the travel control unit 140 may reduce the speed of the vehicle 40. Further, the travel control unit 140 may stop the vehicle 40 for a certain period of time at the timing when the distance between the vehicle 40 and the wireless power transmission device 30 becomes the closest. By doing so, the power transmission efficiency is improved.

[0059] When the map information storage unit 150 stores information indicating the position of the wireless power transmission device 30, the travel control unit 140 may acquire this information from the map information storage unit 150 as the third position information.

[0060] Also, as shown in FIGS. 14 and 15, a mark 52 indicating the position of the wireless power transmission device 30 may be provided on the road 50. An example of the mark 52 is a pattern drawn on the road surface of the road 50.

[0061] In the example shown in FIG. 14, the mark 52 is provided at a position overlapping the wireless power transmission device 30 for each of the plurality of wireless power transmission devices 30.

[0062] In the example shown in FIG. 15, the mark 52 is provided in front of the wireless power transmission device 30 on the road 50. And in the width direction of the road 50, the position of the mark 52 overlaps the position of the wireless power transmission device 30. When a plurality of wireless power transmission devices 30 are arranged side by side in the width direction of the road 50, the mark 52 is provided for each of the plurality of wireless power transmission devices 30.

[0063] When the mark 52 is provided on the road 50, the transmission device 10 may have a second detection unit 160 that detects the mark 52 and generates third position information as shown in FIG. 16. The second detection unit 160 detects the mark 52 using, for example, the detection result of a sensor mounted on the vehicle 40, and generates third position information using this detection result. As an example, the second detection unit 160 uses the detection result of this sensor to generate information indicating the presence of the mark 52 and the position of the mark 52 in each of the longitudinal and width directions of the road 50. The sensor used here is, for example, an imaging device or LiDAR (Light Detection And Ranging). This sensor may be mounted on the vehicle 40 in advance or on the transmission device 10.

[0064] Then, the travel control unit 140 controls the travel of the vehicle 40 using the third position information generated by the second detection unit 160.

[0065] For example, when the distance between the wireless power transmission device 30 and the vehicle 40 approaches, the travel control unit 140 may reduce the speed of the vehicle 40. Also, the travel control unit 140 may stop the vehicle 40 for a certain period of time at the timing when the distance between the vehicle 40 and the wireless power transmission device 30 is the closest. By doing so, the power transmission efficiency from the wireless power transmission device 30 to the wireless power reception device 42 is improved.

[0066] Also, as shown in FIGS. 14 and 15, when a plurality of wireless power transmission devices 30 are arranged side by side in the width direction of the road 50 and the marks 52 indicate the positions of the respective wireless power transmission devices 30 in the width direction of the road 50, the travel control unit 140 may control the position of the vehicle 40 in the width direction of the road 50 using the first position information, that is, the information indicating the position of the wireless power receiving device 42 in the width direction of the vehicle 40, and the third position information. For example, the travel control unit 140 controls the position of the vehicle 40 so that the wireless power receiving device 42 is closest to the wireless power transmission device 30 in the width direction of the road 50. Further, when the wireless power receiving device 42 and the wireless power transmission device 30 overlap in the width direction of the road 50, the travel control unit 140 controls the position of the vehicle 40 in the width direction of the road 50 so that the overlapping area between them is maximized. By doing so, the power transmission efficiency from the wireless power transmission device 30 to the wireless power receiving device 42 is improved.

[0067] In addition, in the example shown in FIG. 15, at least one of the shape and pattern of the plurality of marks 52 may be different from each other.

[0068] As shown in FIG. 17, when the road 50 has a plurality of lanes 54 having the same traveling direction, at least one wireless power transmission device 30 may be provided in each of the plurality of lanes 54. In this case, in at least two lanes 54, the positions of the wireless power transmission devices 30 in the width direction of the lanes 54 may be different. In this case, the travel control unit 140 of the vehicle 40 may select a lane 54 using the first position information and control the vehicle 40 to travel in the selected lane 54.

[0069] For example, the third position information indicates the positions of the wireless power transmission devices 30 in the respective lanes 54. Then, the travel control unit 140 selects the lane 54 in which the wireless power receiving device 42 is closest to the wireless power transmission device 30 using the position of the wireless power receiving device 42 indicated by the first position information, and controls the vehicle 40 to travel in the selected lane 54.

[0070] The third position information may be, for example, the information stored in the map information storage unit 150 as described above, or may be generated when the second detection unit 160 detects the mark 52.

[0071] The third position information may be wirelessly transmitted from the outside to the transmission device 10 when the relative position between the vehicle 40 and the area where the wireless power transmission device 30 is installed on the road 50 satisfies the standard, for example, when the distance between the area and the vehicle 40 becomes equal to or less than the reference value. As an example, the signal transmission device 60 shown in FIG. 11 may transmit the third position information of the road 50 corresponding to the signal transmission device 60 to the transmission device 10 of the vehicle 40.

[0072] Even in this way, the power transmission efficiency from the wireless power transmission device 30 to the wireless power reception device 42 is improved.

[0073] As described above, according to the present embodiment, the power transmission control system includes the transmission device 10 having the first detection unit 110 and the transmission unit 120, and the power transmission control device 20 having the acquisition unit 210 and the control unit 220. Therefore, the power transmission control system can bring the distance between the wireless power reception device 42 and the wireless power transmission device 30 closer, or select the wireless power transmission device 30 close to the wireless power reception device 42 among the plurality of wireless power transmission devices 30 to perform the power supply operation. Therefore, the power transmission efficiency from the wireless power transmission device 30 to the wireless power reception device 42 is improved.
