Description

[Technical Field]

[0001] The present disclosure relates to a charging system, a vehicle, and a charging station. [Background technology]

[0002] Charging stations capable of charging the drive batteries installed in battery electric vehicles (hereinafter abbreviated as BEVs) and plug-in hybrid electric vehicles (hereinafter abbreviated as PHEVs) have been put to practical use. Patent Document 1 listed below discloses technology for linking charging stations with electronic key systems.

[0003] According to the technology described in Patent Document 1 below, if a vehicle user loses a portable device that serves as an electronic key while the electric vehicle is being charged, the portable device can be searched for using a removable portable communication device search unit provided at the charging station. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2014-024458 Summary of the Invention [Problem to be solved by the invention]

[0005] The inventors of the present invention have been studying technology for installing charging stations such as those described above in home parking lots and other locations. When installing a charging station in such a location, it is desirable to be able to charge one's own car and the cars of family members. At the same time, it is desirable to prevent other people's cars from charging without permission. In some cases, it may also be desirable to allow friends' cars to be charged.

[0006] Generally, a mechanism for allowing only specific users to use equipment involves the adoption of an authentication system in which a password or personal identification number (hereinafter collectively referred to as a password, etc.) is required to be entered when using the equipment, and the equipment can be used only if the correct password, etc. is entered.

[0007] However, if such an authentication system is adopted, even if a legitimate user uses a charging station, they will be required to enter a password or other information every time they use the charging station, which will be a considerable amount of work.In addition, it will be necessary to properly manage passwords, such as making sure not to forget them and not letting others know them.

[0008] In this context, the present inventors have studied mechanisms for making it easier to use charging stations and have arrived at the technical idea of ​​the present disclosure. In one aspect of the present disclosure, it is desirable to provide a charging system that can appropriately determine whether a vehicle is a target for charging and then perform charging. [Means for solving the problem]

[0009] One aspect of the present disclosure is a charging system (1) including vehicles (20A, 20B, 20C) and a charging stand (40). The vehicles include first communication units (31, 32), a first storage unit (30B), an authentication unit (30A), and a first control unit (30A). The first communication unit wirelessly communicates with portable devices (60A, 60B, 60C) carried by users and receives first information from the portable devices, the first information being capable of identifying each portable device. The first storage unit stores second information. The authentication unit performs authentication based on the first information received by the first communication unit and the second information stored in the first storage unit. When authentication is successful in the authentication unit, the first control unit controls a control target mounted on the vehicle to operate the control target. The charging stand includes a second storage unit (74), second communication units (42, 43), and a second control unit (41). The second storage unit stores first information acquired from a portable device corresponding to the vehicle. The second communication unit, when a request for charging the vehicle is made, wirelessly communicates with the vehicle and transmits the first information stored in the second storage unit to the vehicle, and when authentication is successful in the vehicle, wirelessly communicates with the vehicle and receives an authentication success notification transmitted from the vehicle. The second control unit, when the second communication unit receives the authentication success notification, charges the vehicle, but does not charge the vehicle if the second communication unit does not receive the authentication success notification. The first communication unit, when a request for charging the vehicle is made, wirelessly communicates with the charging stand and receives from the charging stand the first information stored in the second storage unit (S303). Furthermore, the first communication unit is configured so that the authentication unit performs authentication based on the first information received from the charging stand and the second information stored in the first storage unit (S305), and when the authentication is successful (YES in S307), wirelessly communicates with the charging stand and transmits an authentication success notification to the charging stand (S311).

[0010] In the charging system configured as described above, the vehicle and the portable device constitute a control system that controls a control target mounted on the vehicle. Also, the vehicle and the charging station constitute a charging system capable of charging the vehicle. In configuring such a charging system, the second storage unit stores first information acquired from the portable device corresponding to the vehicle.

[0011] When a request for charging of the vehicle is made, the second communication unit wirelessly communicates with the vehicle and transmits the first information stored in the second storage unit to the vehicle. At this time, the first communication unit wirelessly communicates with the charging stand and receives the first information stored in the second storage unit from the charging stand. In the vehicle, the authentication unit performs authentication based on the first information received by the first communication unit and the second information stored in the first storage unit.

[0012] If the authentication is successful, the first communication unit communicates wirelessly with the charging stand and transmits an authentication success notification to the charging stand. At this time, the second communication unit communicates wirelessly with the vehicle and receives the authentication success notification transmitted from the vehicle. If the second communication unit receives the authentication success notification, the second control unit charges the vehicle. On the other hand, if the second communication unit does not receive the authentication success notification, the second control unit does not charge the vehicle.

[0013] The charging system described above can be configured by utilizing part of the configuration of the control system described above. Therefore, compared to a charging system configured without utilizing the configuration of the control system described above, part of the configuration can be shared between the control system and the charging system, thereby reducing the number of devices to be installed in the vehicle.

[0014] Furthermore, if the first information acquired from the portable device is stored in the first storage unit, when the vehicle corresponding to the portable device and the charging stand communicate with each other thereafter, authentication by the authentication unit is established, and the charging stand can charge the vehicle. This eliminates the need to input a password or the like every time the vehicle is charged, and eliminates the need to manage such passwords or the like.

[0015] The vehicle that constitutes a charging system together with the charging station, and the charging station that constitutes a charging system together with the vehicle, are also novel and useful. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] Next, the above-mentioned charging system will be described with reference to an exemplary embodiment. [Charging system configuration] As shown in Fig. 1, the charging system 1 described below is a system used when vehicles 20A, 20B, and 20C are parked in parking spaces 11 provided in a home parking lot 10 and charging the vehicles 20A, 20B, and 20C. The vehicles 20A, 20B, and 20C are, for example, BEVs or PHEVs, and are equipped with a drive battery (not shown). Since the vehicles 20A, 20B, and 20C are configured almost identically, the following description will focus on vehicle 20A in detail, and Fig. 1 also illustrates the detailed configuration of vehicle 20A.

[0018] The vehicle 20A is provided with a verification ECU 30, an LF transmitter 31, an RF receiver 32, a charging start / stop switch 33, an in-vehicle monitor 34, an ignition switch 35, etc. ECU is an abbreviation for Electronic Control Unit. LF is an abbreviation for Low Frequency. RF is an abbreviation for Radio Frequency.

[0019] A charging stand 40 is installed in the home parking lot 10. The charging stand 40 is a facility for charging the vehicles 20A, 20B, and 20C. The charging stand 40 is provided with a CPU 41, an LF receiver 42, an RF transmitter 43, a speaker 44, a camera 45, a charging control unit 46, and the like. The CPU 41 functions as a charging function unit 41A by executing a charging process described below. The CPU 41 also functions as a key information registration function unit 41B by executing a key information registration process described below. When charging the vehicle 20A, the vehicle 20A and the charging stand 40 are connected via a charging cable 55.

[0020] Vehicle 20A is equipped with a passive entry / passive start (hereinafter abbreviated as PEPS) system. The PEPS system is composed of vehicle 20A and portable device 60A. Vehicle 20B and portable device 60B together constitute a PEPS system, and vehicle 20C and portable device 60C together constitute a PEPS system. The configurations of portable device 60B and portable device 60C are the same as those of portable device 60A, and therefore are not shown in FIG. 1.

[0021] The portable device 60A includes a CPU 61, a memory 62, an LF receiver 63, and an RF transmitter 64. When a user of the vehicle 20A touches a door handle or a back door opener switch (not shown), the LF transmitter 31 is activated to form an LF transmission area in the vicinity of the door handle or the back door opener switch. The vicinity of the door handle or the back door opener switch here refers to, for example, a range of approximately 40 cm to 80 cm around the door handle or the back door opener switch.

[0022] When a user carries portable device 60A within this LF transmission area, portable device 60A receives information transmitted from LF transmitter 31 at LF receiver 63. When this LF communication is established, CPU 61 of portable device 60A reads key information A stored in memory 62 from memory 62 and controls RF transmitter 64 to transmit key information A to vehicle 20A.

[0023] In the vehicle 20A, the RF receiver 32 receives the key information A transmitted from the portable device 60A. The CPU 30A included in the verification ECU 30 verifies the key information A received by the RF receiver 32 with the key information A stored in the memory 30B, and determines that authentication is successful if the two match, and determines that authentication is unsuccessful if the two do not match. If authentication is successful, the verification ECU 30 recognizes that the portable device 60A present near the door handle is the portable device 60A corresponding to the vehicle 20A. In this case, the verification ECU 30 transmits the successful authentication to an ECU that controls locking and unlocking of a locking device attached to the door (not shown), and locking or unlocking control of the locking device is executed.

[0024] When comparing the key information A received by the RF receiver 32 with the key information A stored in the memory 30B, it is possible to simply compare whether they match, or to transmit and receive encrypted key information A and decrypt the key information A before comparing. Alternatively, it is also possible to perform a logical operation on key information A with a predetermined value before comparing.

[0025] When the user touches a trunk opener switch (not shown), the vehicle 20A and the portable device 60A execute similar processes to lock or unlock the locking device attached to the trunk. When the user touches the ignition switch 35 inside the vehicle 20A, the vehicle 20A and the portable device 60A execute similar processes to control the engine or motor starting device.

[0026] As described above, the portable device 60A is a device that constitutes the PEPS system together with the vehicle 20A, but this portable device 60A is also commonly used as a device that constitutes the charging system 1. More specifically, the charging stand 40 includes an LF transmitter 71, a key information registration switch 72, an RF receiver 73, and a memory 74, and is configured to be able to acquire key information A from the portable device 60A by communicating with the portable device 60A.

[0027] That is, the LF transmitter 71 and RF receiver 73 provided in the charging stand 40 are configured to behave in the same manner as the LF transmitter 31 and RF receiver 32 provided in the vehicle 20A when viewed from the portable device 60A. Therefore, as will be described in detail later, when communication is established between the charging stand 40 and the portable device 60A, the portable device 60A transmits key information A to the communication partner without particularly distinguishing whether the communication partner is the vehicle 20A or the charging stand 40.

[0028] The charging stand 40 stores the key information A acquired from the portable device 60A in the memory 74. A key information list as shown in FIG. 2 is stored in the memory 74, and the above-mentioned key information A is registered in the key information list. As shown in FIG. 2, the key information list is configured so that multiple pieces of key information can be registered. The key information list illustrated in FIG. 2 has three pieces of key information registered therein: key information A, key information B, and key information C.

[0029] In this embodiment, key information A is information stored in vehicle 20A, which is the owner's own car, and portable device 60A. Key information B is information stored in vehicle 20B, which is a family member's car, and portable device 60B. Key information C is information stored in vehicle 20C, which is a friend's car, and portable device 60C.

[0030] In the key information list, a start date and time and an end date and time can be set for each piece of key information. These start date and time and end date and time indicate the validity period of the key information. If the actual date and time recognized by the charging station 40 is earlier than the start date and time, the key information is treated as invalid even if it is registered in the key information list. Furthermore, if the actual date and time recognized by the charging station 40 is later than the end date and time, the key information is treated as invalid and is deleted from the key information list.

[0031] Key information for which the start date and time and the end date and time are not registered is always treated as valid key information. Note that, in addition to the start date and time and the end date and time, a flag indicating whether the key information is valid or invalid may be set for each key information. In the key information list illustrated in FIG. 2, key information A corresponds to vehicle 20A, which is the owner's own car, and therefore no validity period is set for the key information so that it can be charged at any time. Key information B also corresponds to vehicle 20B, which is a family member's car, and therefore no validity period is set for the key information so that it can be charged at any time.

[0032] On the other hand, since key information C corresponds to vehicle 20C, which is a friend's car, the validity period of key information C is set taking into consideration the friend's planned visit. As a result, charging of vehicle 20C is possible as long as it is within the validity period of key information C. Furthermore, once the validity period of key information C expires, key information C is deleted, and charging of vehicle 20C becomes impossible thereafter. In this case, if charging of vehicle 20C is to be permitted again, key information C must be registered again in the key information list.

[0033] [Key information registration process] Next, the key information registration process will be described with reference to FIG. The key information registration process is executed by the CPU 41 of the charging stand 40 when the CPU 41 functions as the key information registration function unit 41B. The left side of Fig. 3 illustrates the key information registration process executed by the CPU 41, and the right side of Fig. 3 illustrates the key information transmission process executed in parallel with the key information registration process by the CPU 61 of the portable device 60A. The key information registration process is executed when the user operates the key information registration switch 72 provided in the charging stand 40.

[0034] When the key information registration process starts, in S101, the CPU 41 controls the LF transmitter 71 to transmit a key information request by LF. At this time, an LF transmission area is formed near the LF transmitter 71. If the portable device 60A is present within this LF transmission area, in S201, the CPU 61 controls the LF receiver 63 to receive the key information request by LF. Subsequently, in S203, the CPU 61 transmits key information A read from the memory 62 by RF.

[0035] At this time, in S103, the CPU 41 controls the RF receiver 73 to receive key information A via RF. Subsequently, in S105, the CPU 41 determines whether the key information A received in S103 is unregistered key information. In S105, the CPU 41 determines whether the key information A is unregistered by referring to the key information list stored in the memory 74. If the key information is not unregistered in S105, that is, if the key information is registered, the determination in S105 is NO, and in this case, the key information registration process is terminated. On the other hand, if the key information is unregistered in S105, the determination in S105 is YES, and in this case, the process proceeds to S107. In S107, the CPU 41 additionally registers the received key information in the key information list.

[0036] Next, in S109, the CPU 41 determines whether or not an expiration date has been input. The expiration date can be arbitrarily input by the user using a UI (not shown) of the charging stand 40. Examples of the UI of the charging stand 40 include an operation panel provided in the charging stand 40, or an operation panel provided in a communication terminal connected to the charging stand 40 wirelessly or via a cable.

[0037] If no expiration date has been input in S109, a NO determination is made in S109, and in this case, the key information registration process is terminated. On the other hand, if an expiration date has been input in S109, a YES determination is made in S109, and in this case, the process proceeds to S111. In S111, the CPU 41 stores the expiration date in the memory 74. More specifically, in S111, the expiration date is registered in the key information list stored in the memory 74. Once S111 is completed, the key information registration process is terminated.

[0038] By executing the key information registration process as described above, key information is registered in a key information list such as that shown in Fig. 2. In the case of the key information list illustrated in Fig. 2, key information A and key information B correspond to information that was added and registered in S107 and for which it was determined in S109 that no expiration date had been entered. Key information C corresponds to information that was added and registered in S107 and for which it was determined in S109 that an expiration date had been entered and for which the start date and end date and time of the expiration date were stored in S111.

[0039] [Charging request processing and charging processing] Next, the charge request process and the charge process will be described with reference to FIGS. The charging request process is a process executed by the CPU 30A provided in the verification ECU 30 of the vehicle 20A. The charging process is a process executed by the CPU 41 of the charging stand 40 when the CPU 41 functions as the charging function unit 41A. The charging request process is executed when a user operates the charging start / stop switch 33 provided in the vehicle 20A. The charging process is executed in conjunction with the execution of the charging request process in the vehicle 20A.

[0040] When executing the charge request process in vehicle 20A, first, as a preliminary preparation, vehicle 20A is parked in parking space 11 in home parking lot 10, and vehicle 20A is connected to charging stand 40 via charging cable 55. By parking vehicle 20A in parking space 11, LF receiver 42 provided in charging stand 40 can be positioned within the LF transmission area formed by LF transmitter 31 provided in vehicle 20A. Once such preliminary preparation is complete, the user operates charging start / stop switch 33 provided in vehicle 20A, and the charge request process is executed in vehicle 20A.

[0041] 4, when the charging request process is started, the CPU 30A controls the LF transmitter 31 to transmit a key information request by LF in S301. At this time, an LF transmission area is formed near the LF transmitter 31. If an LF receiver 42 is present within this LF transmission area, the CPU 41 of the charging stand 40 starts the charging process.

[0042] 5, when the charging process starts, the CPU 41 controls the LF receiver 42 to receive a key information request via LF in S401. Then, in S403, the CPU 41 controls the RF transmitter 43 to transmit, via RF, key information read from the key information list stored in the memory 74. If multiple pieces of key information are registered in the key information list, these pieces of key information are transmitted sequentially in S403.

[0043] The specific procedure for sequentially transmitting multiple pieces of key information is not particularly limited, but for example, multiple pieces of key information may be transmitted in order, and a transmission completion notice may be transmitted at the end to terminate the transmission. Alternatively, each time a piece of key information is transmitted, a response indicating that the key information has been received may be waited for, and once the response is received, the next piece of key information may be transmitted.

[0044] When S403 is executed at charging stand 40, CPU 30A in vehicle 20A controls RF receiver 32 to receive key information via RF in S303 shown in Fig. 4. As described above, if multiple pieces of key information are transmitted in S403 shown in Fig. 5, the multiple pieces of key information are received in S303 shown in Fig. 4.

[0045] Next, CPU 30A collates the key information in S305, as shown in Fig. 4. In S305, the key information received by RF receiver 32 in S303 is collated with key information A stored in memory 30B, and if they match, authentication is established; if they do not match, authentication is not established. If multiple pieces of key information have been received in S303, each of the multiple pieces of key information is collated with key information A stored in memory 30B in S305. When the multiple sets of key information are collated, if there is even one set of key information that matches, authentication is established; if there is not even one set of key information that matches, authentication is not established.

[0046] Next, in S307, CPU 30A determines whether authentication was successful in S305. If authentication was successful in S305, YES is determined in S307 and the process proceeds to S311. If the process proceeds to S311, CPU 30A controls LF transmitter 31 to transmit an authentication success notification by LF in S311.

[0047] At this time, as shown in FIG. 5, in the charging station 40, the CPU 41 repeats S405, S407, and S409 to wait for a notification from the vehicle 20A. More specifically, in S405, the CPU 41 determines whether or not an authentication success notification has been received via LF. If the authentication success notification has not been received via LF, the result of the determination in S405 is NO, and in this case, the CPU 41 determines whether or not an authentication failure notification has been received via LF. If the authentication failure notification has not been received via LF, the result of the determination in S407 is NO, and in this case, the CPU 41 determines whether or not a timeout has occurred in S409. If the timeout has not occurred, the result of the determination in S409 is NO, and in this case, the process returns to S405.

[0048] In vehicle 20A, when CPU 30A transmits an authentication success notification via LF in S311 shown in Fig. 4 and receives the authentication success notification via LF, a determination of YES is made in S405 shown in Fig. 5, and in this case, the process proceeds to S411. In S411, CPU 30A controls charging control unit 46 to start operation of charging control unit 46. As a result, charging stand 40 starts charging vehicle 20A.

[0049] After charging starts, the CPU 41 provided in the charging stand 40 determines in S413 whether the charging state has reached 100%. If the charging state has not reached 100%, the result of S413 is NO, and the process proceeds to S415. In S415, the CPU 41 controls the RF transmitter 43 to transmit a charging state notification via RF. Subsequently, in S417, the CPU 41 determines whether a charging stop request has been received via LF. If a charging stop request has not been received via LF, the result of S417 is NO, and the process returns to S413.

[0050] Therefore, if the state of charge has not reached 100% and a request to stop charging has not been received via LF, S413, S415, and S417 are repeated, and a charging state notification is sent each time S415 is executed. The charging state notification includes information indicating the current state of charge percentage.

[0051] On the other hand, after completing S311 shown in FIG. 4, the CPU 30A provided in the vehicle 20A determines in S313 whether or not a charging stop operation has been performed. Here, if the user has not operated the charging start / stop switch 33 in the vehicle 20A, the determination in S313 is NO, and the process proceeds to S315. In S315, the CPU 30A determines whether or not a charging completion notification has been received via RF. If a charging completion notification has not been received via RF, the determination in S315 is NO, and the process proceeds to S317. In S317, the CPU 30A determines whether or not a charging status notification has been received via RF. If a charging status notification has not been received via RF, the determination in S317 is NO, and the process returns to S313.

[0052] Therefore, if the user has not operated the charging start / stop switch 33, and the charging completion notification has not been received via RF, and the charging completion notification has not been received via RF, S313, S315, and S317 are repeated. As described above, S413, S415, and S417 are repeated in the charging stand 40, and a charging status notification is sent each time S415 is executed. Therefore, if a charging status notification is received via RF, a determination of YES is made in S317, and the process proceeds to S321. In S321, the charging status is displayed on the in-vehicle monitor 34 based on the information included in the charging status notification. Information indicating the percentage of charging that has been reached is displayed on the in-vehicle monitor 34.

[0053] At the charging stand 40, if the state of charge reaches 100% while the CPU 41 repeats S413, S415, and S417 shown in FIG. 5, a determination of YES is made at S413. In this case, the CPU 41 stops the operation of the charging control unit 46 at S421. As a result, the charging stand 40 stops charging the vehicle 20A. Next, at S423, the CPU 41 controls the RF transmitter 43 to transmit a charging completion notification by RF. After executing S423, the CPU 41 ends the charging process.

[0054] 4, if the CPU 30A of the vehicle 20A receives a charging completion notification via RF, the CPU 30A determines YES in S315 and proceeds to S331. In S331, the CPU 30A displays the charging completion on the in-vehicle monitor 34. After executing S331, the CPU 30A ends the charging request process.

[0055] 4, if the user operates the charging start / stop switch 33, the CPU 30A of the vehicle 20A determines YES in S313 and proceeds to S341. In S341, the CPU 30A controls the LF transmitter 31 to transmit a charging stop request by LF.

[0056] As described above, the charging stand 40 repeats S413, S415, and S417 shown in FIG. 5 . Therefore, when a charging stop request is transmitted from the vehicle 20A, the CPU 41 determines YES in S417 and proceeds to S431. In S431, the CPU 41 stops the operation of the charging control unit 46. As a result, the charging stand 40 stops charging the vehicle 20A. Next, in S433, the CPU 41 controls the RF transmitter 43 to transmit a charging stop notification by RF. After executing S433, the CPU 41 ends the charging process.

[0057] When a charging stop notification is transmitted from charging stand 40, in vehicle 20A, CPU 30A receives the charging stop notification via RF in S343. Next, in S345, CPU 30A displays the charging stop on in-vehicle monitor 34. After executing S343, CPU 30A ends the charging request process.

[0058] The above is the process corresponding to the case where it is determined that authentication is successful in S307 shown in Fig. 4. On the other hand, if it is determined that authentication is not successful in S307 shown in Fig. 4, a NO determination is made in S307 and the process proceeds to S351. If the process proceeds to S351, the CPU 30A controls the LF transmitter 31 to transmit an authentication failure notification by LF. Next, in S353, the CPU 30A displays on the in-vehicle monitor 34 that charging is not possible, and then ends the charge request process.

[0059] When an authentication failure notification is sent from vehicle 20A, the CPU 41 at charging stand 40 repeats S405, S407, and S409 shown in Fig. 5, and determines YES in S407, and proceeds to S441. When an authentication failure notification is sent, there is a possibility that a vehicle not registered with charging stand 40 has attempted to charge, so in S441, crime prevention processing is executed. The specific content of the crime prevention processing is arbitrary, but it is preferable to execute, for example, recording the date and time, taking a photo with camera 45, and issuing a warning via speaker 44.

[0060] The date and time may be recorded internally in the charging stand 40, or may be stored in an external device configured to be able to communicate with the charging stand 40, or may be sent to a mobile terminal carried by the user by means of e-mail or the like. The images taken by the camera 45 may be either video or still images. These video or still image data may be stored internally in the charging stand 40, or may be sent to an external device configured to be able to communicate with the charging stand 40. The warning from the speaker 44 may be an audible warning, or a verbal warning message may be issued. After completing S441, the CPU 41 ends the charging process.

[0061] In S403, if an authentication success notification or an authentication failure notification is received after the key information is transmitted from the charging stand 40, the above-described processing is executed. However, if the vehicle side does not have a mechanism compatible with the charging stand 40 even though the key information is transmitted from the charging stand 40, it is possible that neither an authentication success notification nor an authentication failure notification is transmitted. Therefore, the CPU 41 determines that a timeout has occurred after a certain period of time has elapsed, and in this case, a YES determination is made in S409, and the processing proceeds to S441 described above. In other words, S441 is executed in both cases, namely, when an authentication failure notification is received and when a timeout occurs.

[0062] [effect] (1) The vehicle 20A and the portable device 60A constitute a control system that controls a control target mounted on the vehicle 20A. The vehicle 20A and the charging stand 40 constitute a charging system 1 that can charge the vehicle 20A. In configuring such charging system 1, key information A obtained from the portable device 60A corresponding to the vehicle 20A is stored in a memory 74 provided in the charging stand 40.

[0063] When charging of vehicle 20A is requested, LF receiver 42 and RF transmitter 43 communicate wirelessly with vehicle 20A and transmit key information A stored in memory 74 to vehicle 20A. At this time, LF transmitter 31 and RF receiver 32 communicate wirelessly with charging stand 40 and receive key information A stored in memory 74 from charging stand 40. In vehicle 20A, CPU 30A performs authentication based on key information A received by LF transmitter 31 and RF receiver 32 and key information A stored in memory 30B.

[0064] If the authentication is successful, the LF transmitter 31 and the RF receiver 32 communicate wirelessly with the charging stand 40 and transmit an authentication success notification to the charging stand 40. At this time, the LF receiver 42 and the RF transmitter 43 communicate wirelessly with the vehicle 20A and receive the authentication success notification transmitted from the vehicle 20A. If the LF receiver 42 and the RF transmitter 43 receive the authentication success notification, the CPU 41 charges the vehicle 20A. On the other hand, if the LF receiver 42 and the RF transmitter 43 do not receive the authentication success notification, the CPU 41 does not charge the vehicle 20A.

[0065] With the charging system 1 as described above, it is possible to configure the charging system 1 as described above by using part of the configuration of the control system as described above. Therefore, compared to configuring the charging system 1 without using the configuration of the control system as described above, part of the configuration can be shared between the PEPS system and the charging system 1, and the number of devices to be installed in the vehicle 20A can be reduced.

[0066] Furthermore, once key information A acquired from portable device 60A is stored in memory 30B, authentication by CPU 30A is established when vehicle 20A corresponding to portable device 60A and charging stand 40 communicate with each other. If authentication is established, charging stand 40 can charge vehicle 20A. Therefore, it is not necessary to input a password or the like every time charging vehicle 20A is performed, and there is no need to manage such a password or the like.

[0067] (2) In this embodiment, CPU 30A is configured to control locking devices attached to the doors or trunk of vehicle 20A and the engine or motor mounted on vehicle 20A as control targets, and is configured to be able to control the locking / unlocking of the doors or trunk by the locking devices and the starting of the engine or motor. That is, CPU 30A, LF transmitter 31, and RF receiver 32, together with portable device 60A, constitute a PEPS system in vehicle 20A. With the charging system 1 described above, the charging system 1 described above can be configured using part of the configuration of the PEPS system described above.

[0068] (3) In this embodiment, the memory 74 is configured to store multiple pieces of key information A, B, and C acquired from multiple portable devices 60A to 60C associated with the vehicles 20A to 20C. Therefore, charging can be performed for multiple vehicles 20A to 20C.

[0069] (4) In this embodiment, the RF transmitter 43 transmits multiple pieces of key information A, B, and C stored in the memory 74 to the vehicle 20A. The RF receiver 32 receives the multiple pieces of key information A, B, and C from the portable device 60A. The CPU 30A repeats authentication multiple times based on each of the multiple pieces of key information A, B, and C received by the RF receiver 32 and the key information A stored in the memory 30B. If one of the multiple authentications is successful, the CPU 30A wirelessly communicates with the charging stand 40 and transmits an authentication success notification to the charging stand 40. Therefore, if the key information A stored in the memory 30B is included in the multiple pieces of key information A, B, and C received by the RF receiver 32, the charging process can be executed appropriately.

[0070] (5) In this embodiment, when predetermined operating conditions are met in vehicle 20A, LF transmitter 31 and RF receiver 32 are configured to wirelessly transmit a request signal to charging stand 40 to start wireless communication with charging stand 40. When charging stand 40 receives the request signal, it transmits key information A stored in memory 74 to vehicle 20A. Therefore, the charging process can be started when the operating conditions are met on the vehicle 20A side.

[0071] (6) In this embodiment, vehicle 20A is provided with charging start / stop switch 33 that is operated when a user issues a command to start charging. When charging start / stop switch 33 is operated, LF transmitter 31 determines that an operating condition is met in vehicle 20A and transmits a request signal to start wireless communication with charging stand 40 via wireless communication to charging stand 40. Therefore, the charging process can be started in response to the switch operation in vehicle 20A.

[0072] (7) In this embodiment, when the LF receiver 42 does not receive the authentication success notification, the CPU 41 executes a crime prevention process including at least one of recording information to a recording medium, transmitting information to a transmission destination, and issuing an alarm to those in the vicinity. Therefore, when a suspicious vehicle approaches the charging station 40, the crime prevention process can be executed.

[0073] (8) In this embodiment, while the CPU 41 is charging the vehicle 20A, the RF transmitter 43 transmits a charging status notification to notify the vehicle 20A of the progress of charging. The RF receiver 32 receives the charging status notification from the charging stand 40. When the LF transmitter 31 and the RF receiver 32 receive the charging status notification, the CPU 30A outputs the charging progress status from the in-vehicle monitor 34 as information that can be recognized by the user, based on the charging status notification. Therefore, the user can recognize the charging progress status by looking at the in-vehicle monitor 34.

[0077] (A) For example, in the above embodiment, a single piece of key information A is stored in the memory 30B of the vehicle 20A. However, multiple pieces of key information may be stored in the memory 30B of the vehicle 20A. For example, if multiple portable devices are associated with one vehicle 20A, multiple pieces of key information corresponding to each of the multiple portable devices may be stored in the memory 30B.
