[0016] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In addition, in all the drawings of the following embodiments, the same or corresponding parts are denoted by the same reference numerals. Further, the present disclosure is not limited to the embodiments described below.
[0017] (Embodiment)
[0018] First, a power supply control system according to an embodiment will be described. Figure 1 It is a schematic diagram showing a power supply control system including a power supply management device according to an embodiment. Figure 2 It is a block diagram for explaining the configuration of a vehicle (vehicle control device) according to an embodiment. Figure 3 It is a diagram showing an example of a vehicle and a driving lane in a power supply control system according to an embodiment. [[ID=’39]]
[0019] As Figure 1 shown, the power supply control system 1 according to this embodiment includes a driving lane management device 20, vehicles 30, and a power supply management device 40. In the power supply control system 1 according to this embodiment, the driving lane management device 20, each vehicle 30, and the power supply management device 40 are connected via a network 10 so as to be able to communicate with each other. The network 10 is composed of an Internet line network, a mobile phone line network, etc. that can communicate between the driving lane management device 20, the vehicle 30, and the power supply management device 40. In the present embodiment, the vehicle 30 is set to be a vehicle that can travel in a hybrid driving mode or an EV driving mode. The vehicle 30 is charged using the power supplied from the power supply device 41 managed by the power supply management device 40.
[0020] The travel lane management device 20 controls the queue of vehicles 30 traveling on the travel lane and sends information for controlling the power supply method in the travel lane to the power supply management device 40. The travel lane management device 20 includes a control information creation unit 21, a control unit 22, and a storage unit 23. The travel lane management device 20 is constituted by one or more computers including a CPU (Central Processing Unit), an FPGA (Field Programmable Gate Array), a ROM (Read Only Memory), and a RAM (Random Access Memory). The travel lane management device 20 corresponds to a travel control device.
[0021] Based on the received disaster-related information, the control information creation unit 21 creates travel lane control information for controlling the power supply in the travel lane.
[0022] The control unit 22 comprehensively controls the operations of the respective units of the travel lane management device 20.
[0023] The storage unit 23 is constituted by a computer-readable recording medium and stores various programs and various data in a writable and readable manner. As this recording medium, it is configured to have a storage medium such as an optical disk, a flash memory, a magnetic disk, and a driving device for these storage media.
[0024] In addition, the storage unit 23 stores the power supply control information used when the control information creation unit 21 creates control information. This power supply control information includes the power supply ratios allocated to each travel lane in the normal state and when a disaster occurs. The "normal" state mentioned here refers to a state where there is no obstacle to the travel of the vehicle 30 due to an accident, a disaster, or the like.
[0025] [[ID=!5]]The power supply ratio is, for example, the ratio of the allocated power to the total power that can be supplied to the travel lane of the power supply target. In the normal state, the same ratio is set for each travel lane, and in the event of a disaster, the ratio is set according to the width of the travel lane. The power supply ratio in the event of a disaster is set such that the wider the travel lane in which the vehicle 30 is traveling, the higher the priority of the power supply.
[0026] In this embodiment, non-contact charging is implemented between the vehicle 30 and the power supply device 41. Communication is performed between the receiving unit 31 provided in the vehicle 30 and the power supply device 41 connected to the power supply management device 40, thereby transmitting a power supply signal to the vehicle 30. The receiving unit 31 and the power supply device 41 are each constituted by, for example, a coil, a switching circuit, and a rectifying and smoothing circuit, and the power supply signal is transmitted and received by magnetic field resonance. Thus, the vehicle 30 and the power supply device 41 communicate in a non-contact state. The power supply device 41 preferably extends along the driving lane on the basis of taking a longer power supply section. In addition, in this embodiment, an example of power supply and information transmission using electromagnetic waves is described, but it may also be configured to perform power supply / information transmission using light.
[0027] In addition, the receiving unit 31 may not accept the input of the power supply signal when the remaining charge amount of the battery in the vehicle 30 reaches the upper limit value. The remaining charge amount is, for example, SOC (State Of Charge).
[0028] The power supply device 41 is provided in a plurality of lanes (driving lanes) on which the vehicle travels and is electrically connected to the power supply management device 40. In addition, in this embodiment, the power supply device 41 may also have a detection function for detecting the vehicle 30 located on the power supply device 41 and a receiving function for receiving information of the vehicle 30. The detection function and the receiving function are each constituted by, for example, a loop antenna. For example, regarding the detection function, a detection signal is transmitted to the power supply management device 40 when the vehicle 30 is detected. In addition, if the vehicle can be detected by a coil for power supply or the like, the coil may also be used as a detection coil in common with the power supply. [[ID=,8]]
[0029] Next, refer to Figure 2 The configuration of the vehicle 30 will be described. The vehicle 30 includes a receiving unit 31, a communication unit 32, a GPS (Global Positioning System) unit 33, an input / output unit 34, and an ECU (Electronic Control Unit) 35. In addition, a battery 36 for supplying power to each unit is provided in the vehicle 30. The battery 36 is configured to be rechargeable. In this embodiment, the vehicle control device 300 is constituted by the communication unit 32, the GPS unit 33, the input / output unit 34, and the ECU 35. The vehicle control device 300 is constituted by one or more computers including a CPU, an FPGA, a ROM, a RAM, and the like.
[0030] The receiving unit 31 receives a power supply signal from the power supply device 41. In addition, the receiving unit 31 can be configured to obtain energy from a power supply device 41 such as light, or can load its own information onto an electromagnetic wave and send it to the power supply device 41. The receiving unit, the obtaining unit, and the sending unit can also be provided separately instead of integrally. The power supply signal received by the receiving unit 31 is supplied as electric power to the battery 36.
[0031] The communication unit 32 communicates with the driving lane management device 20 via wireless communication over the network 10. The communication unit 32 receives driving support information for supporting the driving of the vehicle 30 from the driving lane management device 20. In addition, the driving support information includes road traffic information such as restrictions and congestion. Additionally, the communication unit 32 can also be configured to send its own information to the power supply management device 40.
[0032] The GPS unit 33 receives radio waves from GPS satellites and detects the position of the vehicle 30. The detected position is output as the position information of the vehicle 30 to the outside (the driving lane management device 20) or stored in the storage unit.
[0033] In addition, the input / output unit 34 is composed of a touch panel display, a speaker, a microphone, etc. The input / output unit 34 is configured to be able to display characters, graphics, etc. on the screen of the touch panel display and output sound from the speaker according to the control of the ECU 35, so as to input and output predetermined information such as information related to driving support. Additionally, the input / output unit 34 is configured to be able to input predetermined information to the ECU 35 by the user of the vehicle 30 operating the touch panel display and speaking towards the microphone.
[0034] The ECU 35 is composed of an information processing device such as a microcomputer including a CPU, an FPGA, a ROM, and a RAM, etc. The ECU 35 comprehensively controls the electrical operations of each part of the vehicle 30. The ECU 35 is configured to perform calculations using the input data, pre-stored data, and programs, and output the calculation results as control instruction signals.
[0035] In addition, the vehicle 30 is equipped with a storage unit, sensors for detecting objects approaching the vehicle 30, etc. The storage unit includes storage media such as hard disks and semiconductor memories and driving devices for these storage media. The operating system (OS) and various application programs required for the ECU 35 to comprehensively control the operations of each part of the vehicle 30 are stored in the storage unit.
[0036] In addition, the vehicle 30 is equipped with a control mechanism and an operating mechanism for driving the vehicle 30. Specifically, the vehicle 30 is equipped with a power transmission system and drive wheels as the driving mechanism. The power transmission system includes a power source that generates driving force and outputs it from the output shaft, and a power transmission mechanism that transmits the driving force output by the power source to the drive wheels.
[0037] In addition, the operating mechanism is composed of a gear shift lever, an accelerator pedal, etc.
[0038] The power supply management device 40 is connected to the power supply device 41, receives the information obtained by the power supply device 41 from each vehicle 30, and controls the power supply to the vehicle 30 based on the received information. The power supply management device 40 is constituted by one or more computers including a CPU, an FPGA, a ROM, a RAM, etc.
[0039] In addition, the power supply management device 40 includes a control unit 40a.
[0040] The control unit 40a comprehensively controls the operations of the respective parts of the power supply management device 40. The control unit 40a controls the power supply to the power supply devices 41 provided in each driving lane according to the control information obtained from the driving lane management device 20.
[0041] Here, in the present embodiment, a road 50 provided with driving lanes in which the vehicles 30 travel in the same direction is taken as an example for description. The road 50 includes a first driving lane 51, a second driving lane 52, and a third driving lane 53, and the widths of the respective driving lanes are different from each other. The width mentioned here refers to the length in the direction orthogonal to the traveling direction of the vehicle 30, that is, the longitudinal direction of the driving lane. Specifically, the first driving lane 51, the second driving lane 52, and the third driving lane 53 are arranged in sequence, and the widths of the lanes increase in this order. In addition, Figure 3 The relationship of the widths shown is an example, and is set according to the scale of the road 50 and the vehicles 30 passing through.
[0042] In the normal state, the vehicles 30 travel on each driving lane regardless of the category. As the categories of vehicles, they are roughly divided into vehicles with high urgency and other vehicles. The higher the public nature such as medical treatment and material transportation, the higher the urgency. In addition, the vehicle 30 is classified into small, medium, and large types according to, for example, the weight of the vehicle 30 (including the loadable weight). In the present embodiment, the vehicles with high urgency are classified as large vehicles. For example, in Figure 3 the large vehicle 30 is designated as 30L, the medium vehicle 30 is designated as 30M, and the small vehicle 30 is designated as 30S.
[0043] A plurality of power supply devices 41 are provided at preset intervals on each driving lane. The power supply devices 41 are provided at intervals of, for example, several kilometers. In addition, in Figure 3 an example is shown in which the installation area of the power supply device 41 is smaller (shorter) than the vehicle 30, but it can be made longer than the vehicle 30 or the power supply devices 41 can be made adjacent to each other to adjust the power supply range.
[0044] Next, refer to Figure 4A description will be given of the driving control process performed on the power supply control system 1. Figure 4 It is a timing chart showing the driving control process performed by a power supply control system according to an embodiment.
[0045] First, the control unit 22 of the driving lane management device 20 determines whether disaster-related information (hereinafter referred to as disaster information) has been received (step S101). The disaster information is issued, for example, from disaster prevention centers of the state or local governments. When the control unit 22 determines that no disaster information has been received (step S101: No), it repeatedly performs the reception confirmation. In contrast, when the control unit 22 determines that disaster information has been received (step S101: Yes), it proceeds to step S102. In addition, before obtaining the disaster information, the power supply control (power supply ratio) in the driving lane is in the normal state. That is, on each driving lane, the ratio of power supply is equal.
[0046] In step S102, the control information creation unit 21 creates driving lane control information including the power supply ratio in the driving lane of the disaster area based on the received disaster information. The power supply ratio set here is set in such a way that the power supply to the widest driving lane (for example, Figure 3 the third driving lane in Figure 3 is the largest. Here, in the example shown in
[0047] it can be set, for example, in such a way that the power supply ratio increases in the order of the first driving lane 51, the second driving lane 52, and the third driving lane 53, or in such a way that the power supply ratio of the third driving lane 53 is the largest and the power supply ratios of the first driving lane 51 and the second driving lane 52 are the same.
[0048] The control unit 22 sends the driving lane control information created in step S102 to the power supply management device 40 (step S103). At this time, the driving lane control information is sent to the power supply management device 40 that has jurisdiction over the power supply device 41 in the disaster area.
[0049] In step S105, the control unit 40a changes the power supply control for each driving lane according to the driving lane control information. The control unit 40a controls the ratio of the power supplied to each driving lane according to the power supply ratio. Thus, power is preferentially supplied to the third driving lane 53 with the widest road width. At this time, power may not be supplied to the driving lanes where the vehicle 30 does not travel due to the disaster.
[0050] Through the control of step S105, for example, if a vehicle 30 with high urgency (vehicle 30L) travels on the driving lane with the widest width ( Figure 3 the third driving lane 53 therein) to go to the disaster area or the like, it can travel under stable power supply.
[0051] After that, the control unit 22 determines whether it has received the elimination information indicating that the disaster has subsided and the adverse conditions caused by the disaster have been eliminated (step S106). Here, when the control unit 22 determines that it has not received the elimination information (step S106: No), it repeatedly performs the reception confirmation. In contrast, when the control unit 22 determines that it has received the elimination information (step S106: Yes), it moves to step S107.
[0052] In step S107, the control unit 22 re - sets the power supply ratio of the driving lanes equally and sends the release information including the set power supply ratio to the power supply management device 40.
[0053] The control unit 40a determines whether it has received the release information (step S108). When the control unit 40a determines that it has not received the release information (step S108: No), it repeatedly performs the reception confirmation. In contrast, when the control unit 40a determines that it has received the release information (step S108: Yes), it moves to step S109.
[0054] In step S109, the control unit 40a returns the power supply ratio for supplying power to the power supply devices 41 in each driving lane to the normal ratio (here, equal).
[0055] In the present embodiment described above, in the normal state where the driving lane management device 20 supplies power equally to a plurality of driving lanes with different widths regardless of the driving lane, when a disaster occurs, it controls in such a way that the power supply to the driving lane with the widest width is prioritized. According to the present embodiment, in the event of a disaster, if a vehicle 30 with high urgency travels on the driving lane with the widest width to go to the disaster area or the like, it can travel under stable power supply. As a result, in the event of a disaster or the like, the state where vehicles with high public nature can travel can be maintained.
[0056] In addition, in the embodiment, an example in which each vehicle 30 travels by manual driving according to the driver's operation has been described. However, it can also be applied to a case where each vehicle 30 that controls the travel lane and speed of each vehicle 30 by the travel lane management device 20 travels by autonomous driving.
[0057] (Modification example)
[0058] Figure 5 FIG. is a schematic diagram showing a power supply control system according to a modification example. With respect to the configuration of the power supply control system 1 in the embodiment, the power supply control system 1A in the modification example includes a power supply management device 40A instead of the power supply management device 40, and also includes a disaster area determination device 60. Hereinafter, parts different from the embodiment (the power supply management device 40A, the disaster area determination device 60, and the processing content) will be described. In addition, in this modification example, the power supply management device 40A receives information on the SOC associated with the time from the communication unit 32 of the vehicle 30.
[0059] The power supply management device 40A is connected to the power supply device 41. The power supply device 41 receives information such as the SOC from each vehicle 30 and controls the power supply to the vehicle 30. The power supply management device 40A is configured by using one or more computers including a CPU, an FPGA, a ROM, a RAM, and the like. The power supply device 41 outputs the acquired transmission information to the power supply management device 40A.
[0060] In addition, the power supply management device 40A includes a power supply efficiency calculation unit 40b and a control unit 40c.
[0061] The power supply efficiency calculation unit 40b calculates the power supply rate (power supply efficiency) per unit time based on the SOC acquired from the vehicle 30 that is the power supply target. The power supply efficiency calculation unit 40b can adopt a known method for calculating the power supply efficiency.
[0062] The control unit 40c comprehensively controls the operations of the respective units of the power supply management device 40A.
[0063] The disaster area determination device 60 receives information related to the power supply efficiency of each vehicle 30 from the power supply management device 40A, and determines whether a disaster has occurred at the power supply location based on the received information, and determines the disaster area. Further, the disaster area determination device 60, for example, sends disaster information to a regional center or the like that has jurisdiction over the location where the disaster has been determined.
[0064] The disaster area determination device 60 includes a disaster determination unit 61, a control unit 62, and a storage unit 63. The disaster area determination device 60 is configured by using one or more computers including a CPU, an FPGA, a ROM, a RAM, and the like.
[0065] The disaster determination unit 61 determines whether a disaster has occurred in the area managed by the power supply management device 40A based on the power supply efficiency obtained from the power supply management device 40A.
[0066] Here, when debris accumulates on the driving lane and this debris is between the vehicle 30 and the power supply device 41, the intensity (transmission efficiency) of the electromagnetic wave decreases, and due to this decrease in intensity, the power supply efficiency decreases. Examples of the debris include liquids such as water, ice (snow), sediment, volcanic ash, and collapsed structures. At this time, multiple thresholds can be set according to the degree of decrease in the power supply efficiency, and the degree of the disaster can be determined based on each threshold. Also, when the reduction rate of the power supply efficiency is different between the debris, a threshold can be set for each piece of debris. In the case of setting the threshold according to the type of debris, the disaster determination unit 61 compares the power supply efficiency with each threshold to determine the type of the disaster (such as a flood, etc.).
[0067] The control unit 62 comprehensively controls the operations of each part of the disaster determination device 60.
[0068] The storage unit 63 is constituted by a computer-readable recording medium, and various programs and various data are stored in a writable and readable manner. As this recording medium, it is configured to have storage media such as optical discs, flash memories, magnetic disks, and drive devices for these storage media.
[0069] In addition, the storage unit 63 stores the thresholds used by the disaster determination unit 61 when determining whether a disaster has occurred. The threshold is, for example, the lower limit value of the power supply efficiency set based on the reduction rate of the power supply efficiency caused by the debris. For example, multiple thresholds can be set for each model of the power supply device 41, or multiple thresholds can be set based on the reduction rate of the power supply efficiency caused by the type of debris.
[0070] In addition, there is a case where the intensity of the electromagnetic wave increases due to debris or the like. When it is assumed that the power supply efficiency becomes extremely high due to such debris, an upper limit value can also be set for the threshold, so that the disaster determination unit 61 determines that a disaster has occurred even when the upper limit value is exceeded.
[0071] Next, the disaster determination process in the disaster determination device 60 will be described. Figure 6 It is a timing chart showing the disaster determination process performed by the power supply control system of the modified example. In Figure 6 As an example, an example of determining a flood disaster will be described.
[0072] The power supply management device 40A supplies power to the power supply device 41 that has detected the vehicle 30, and performs power supply processing from the power supply device 41 to the vehicle 30 (step S201). For example, the power supply management device 40A obtains the SOC at the start of power supply and the start time of power supply via the power supply device 41. When the power supply processing ends, the power supply management device 40A obtains the SOC at the end of power supply and the end time of power supply via the power supply device 41, for example. In addition, the SOC at the start and end of power supply may be uniformly sent to the power supply management device 40A. At this time, when the SOC reaches the upper limit value during the power supply period, the charging end time becomes the time when the SOC reaches the upper limit value.
[0073] After that, the power supply efficiency calculation unit 40b calculates the power supply efficiency (step S202). For example, the SOC at the time immediately before power supply and the SOC at the time immediately after power supply are obtained from the vehicle 30 to be powered. The power supply efficiency calculation unit 40b calculates the power supply rate (the increase rate of SOC) per unit time based on the obtained times and SOC, and sets it as the power supply efficiency.
[0074] The power supply management device 40A sends the power supply information including the calculated power supply efficiency to the disaster area determination device 60 (step S203). In addition to the power supply efficiency, the power supply information includes information related to the location of the power supply device 41 for which the power supply efficiency is calculated.
[0075] The disaster area determination device 60 determines whether it has received the power supply information (step S204). When the disaster area determination device 60 determines that it has not received the power supply information (step S204: No), it repeatedly confirms the reception of the power supply information. When the disaster area determination device 60 determines that it has received the power supply information (step S204: Yes), it proceeds to step S205.
[0076] In step S205, the disaster area determination device 60 determines whether a flood has occurred based on the power supply efficiency. Specifically, the disaster determination unit 61 determines whether a flood has occurred at the location managed by the power supply management device 40A based on the power supply efficiency obtained from the power supply management device 40A. Furthermore, the disaster determination unit 61 estimates the flood area based on the location (area) of the power supply device 41 to be determined.
[0077] Specifically, the disaster determination unit 61 compares the power supply efficiency with the threshold value stored in the storage unit 63. When the power supply efficiency is less than the threshold value, it is determined that a disaster has occurred at the location where the power supply device 41 is installed or in the area including this location. Furthermore, the disaster determination unit 61 estimates the disaster area based on the determination results of each power supply device 41. For example, a region is associated with each installation location of the power supply device 41. When there are multiple power supply devices 41 for which it is determined that a disaster has occurred, the disaster determination unit 61 sets a disaster area formed by combining the regions of each power supply device 41. The disaster location is determined according to the determination result of the disaster determination unit 61.
[0078] In addition, the disaster determination unit 61 may also determine whether a disaster has occurred based on the number and continuity of the power supply devices 41 with a power supply efficiency lower than the threshold value. For example, when the disaster determination unit 61 determines that a disaster has occurred for a predetermined number or more of the power supply devices 41 among all the power supply devices 41 managed by the power supply management device 40, it is determined that a disaster has occurred in the area managed by the power supply management device 40. In addition, when the number (consecutive number) of the power supply devices 41 for which it is determined that a disaster has occurred and whose installation positions are adjacent to each other is a predetermined number or more, the disaster determination unit 61 determines that a disaster has occurred in the area managed by the power supply management device 40. "Adjacent to each other" here means adjacent in the same driving lane, or the respective power supply devices are arranged in one driving lane among multiple driving lanes and are adjacent at the closest distance.
[0079] The disaster location determination device 60 generates flood occurrence information based on the determination result of the disaster determination unit 61 (step S206). The disaster location determination device 60 generates information including the flood occurrence area determined by the disaster determination unit 61 as the flood occurrence information. In addition, when the degree of the flood is determined by setting a threshold value, the information is also included in the flood occurrence information.
[0080] The disaster location determination device 60 distributes the flood occurrence information to the driving lane management device 20, the regional center that manages the flood area, etc. (step S207). When receiving the flood occurrence information, the regional center distributes the information to the regional center of the area, notifies the occurrence of the flood through disaster prevention broadcasting, sets a traffic prohibition area, and stops the operation of the power supply device 41 in this area.
[0081] The driving lane management device 20 performs the same power supply control on the area where the flood has occurred as the implementation method (refer to Figure 4 ). Specifically, it implements control to prioritize the power supply to the widest driving lane. At this time, when the widest driving lane is flooded and the vehicle 30 cannot drive, the power supply to the second widest driving lane is prioritized. In addition, for the flooded driving lane, the supplied power can be reduced or power supply (cut-off) can be stopped.
[0082] In this variation described above, similar to the embodiment, the lane management device 20 normally supplies power equally to multiple lanes of varying widths. However, in the event of a disaster, the device controls the system to prioritize power supply to the widest lane. According to this variation, during a disaster, if a high-need vehicle 30 travels in the widest lane to reach a disaster site, for example, it can maintain a stable power supply. As a result, during disasters, vehicles with high public access can continue to travel.
[0083] Furthermore, in this variation, the presence of a disaster is determined by using the power supply efficiency of contactless charging, which varies depending on the presence of debris between the vehicle 30 and the power supply device 41. This variation obtains information from the power supply device 41 that supplies power to the vehicle 30, making it possible to infer the presence of a disaster at the location of the power supply device 41. This allows the disaster site to be identified without the need to introduce new equipment. This allows local officials to identify the occurrence of a disaster without having to visit the site. Furthermore, by using the difference in the rate of reduction in power supply efficiency based on the presence of debris, it is possible to determine the type of disaster, such as flooding or mudslide damage, and to send notifications to the appropriate area.
[0084] Furthermore, in this modified example, since the lane where the disaster occurred can be identified by the placement of each power supply device 41, power supply to the affected lane can be appropriately distributed, thereby efficiently supplying power. Furthermore, since the number of vehicles 30 traveling in the affected lane is extremely reduced, reducing or cutting off the power supply to that lane can suppress wasteful power consumption.
[0085] Furthermore, in this modified example, the disaster determination unit 61 determines whether a disaster has occurred based on the number and continuity of power supply devices 41 whose power supply efficiency is lower than a threshold. This allows for a more accurate determination of whether a disaster has occurred, by distinguishing between a failure of a power supply device 41 and the occurrence of a disaster.
[0086] In this modification, the power supply management device 40A may not include the power supply efficiency calculation unit 40 b , and the disaster site identification device 60 may obtain SOC information from the vehicle 30 , and the disaster determination unit 61 may calculate the power supply efficiency.
