The “request from the administrator (user, owner) of the vehicle 40” may be a request for the administrator to register the vehicle 40 in the car sharing system. The “request from the administrator (user, owner) of the vehicle 40” may be rephrased as permission for the administrator to lend the vehicle 40 to the user of the car sharing system. In addition, when the administrator of the vehicle 40 wants to cancel the registration of the vehicle 40 to the car sharing system (when the rental of the vehicle 40 ends), the group ID assigned to the vehicle 40 by the operation of the administrator of the vehicle 40 is It is preferable that it can be appropriately deleted.

  Note that the server 10 may perform processing such as reservation management of the vehicle 40, permission to use the vehicle 40, and update of the usage history of the vehicle 40 as functions of the car sharing system. For example, the server 10 has a function of communicating with the vehicle 40 (for example, a function of communication between the server 10 and a DCM (Data Communication Module) mounted on the vehicle 10), operation of one or more vehicles used in the car sharing system. Functions for managing each situation, information on the operation status of the vehicle 40 (for example, information on whether the vehicle is sharing or waiting, information on the position of the vehicle 40, date and time information, etc.) and recording (accumulating) It may have a part or all of the function.

  The server 10 may recognize that the vehicle 40 has been returned by receiving a return processing signal from the terminal device 20, the electronic key 30, or the vehicle 40. Further, if the vehicle 40 is not returned after the reservation time has elapsed, the server 10 generates a reservation time overload signal including information indicating that, and the terminal device 20, the electronic key 30, or the vehicle 40. May be sent to.

(Configuration of terminal device 20)
The terminal device 20 performs wireless communication with the server 10 via a communication network such as a mobile phone communication network or the Internet. The terminal device 20 communicates with the server 10 via near field radio communication or the like. Note that the terminal device 20 is a small computer such as a smartphone, a mobile phone, a tablet terminal, a personal information terminal, or a wearable computer (smart watch or the like).

  The terminal device 20 includes a communication unit 21, a memory 22, a control unit 23, and a communication unit 24. For the sake of explanation, the communication unit 21 that communicates with the server 10 and the communication unit 24 that communicates with the electronic key 30 are described separately, but the terminal device 20 may include one communication unit. . In other words, one communication unit may have a function of performing both communication using a mobile phone network and short-range wireless communication. Although not shown, it is preferable that the control unit 23 is connected to at least the communication unit 21, the memory 22, and the communication unit 24 by wired connection or wireless connection. Note that at least the communication unit 21, the memory 22, and the communication unit 24 are preferably controlled by the control unit 23. The control unit 23 may be referred to as an electronic control unit (ECU, Electronic Control Unit). Note that the communication unit 21, the memory 22, the control unit 23, and the communication unit 24 may be referred to as an ECU.

  The communication unit 21 receives the key ID of the vehicle 40 transmitted from the communication unit 13. The memory 22 stores the key ID of the vehicle 40 received by the communication unit 21. The control unit 23 performs preprocessing for transmitting the received key ID of the vehicle 40 to the electronic key 30. The communication unit 24 transmits the key ID of the vehicle 40 to the electronic key 30.

The setting related to the transmission of the key ID of the vehicle 40 used by the control unit 23 may be the same as the setting related to the transmission of the key ID of the vehicle 40 determined by the control unit 12 of the server 10. In this case, the processing load on the control unit 23 can be reduced.

  Note that the communication unit 21 may transmit request information and / or reservation information to the server 10.

  When the terminal device 10 receives the request information and / or reservation information together with the key ID of the vehicle 40 from the server 10, the terminal device 10 receives the key of the received vehicle 40 based on the received request information and / or reservation information. It may be determined whether the ID is addressed to the user. Note that “determine whether or not the received key ID of the vehicle 40 is addressed to itself” means that the terminal device 10 determines whether or not the received key ID of the vehicle 40 is transmitted to the terminal device 10. It may be to do. Note that “determine whether or not the key ID of the received vehicle 40 is addressed to itself” means that the key ID of the received vehicle 40 is transmitted to the terminal device 10 or addressed to a terminal device other than the terminal device 10. It may be that the terminal device 10 determines whether it is transmitted to the terminal.

FIG. 3 is an example of a flow for determining whether or not the received key ID of the vehicle 40 is addressed to itself.
The terminal device 10 receives request information and / or reservation information together with the key ID of the vehicle 40 (step S301). The terminal device 10 determines whether the received request information and / or reservation information corresponds to its own request and / or reservation. For example, the terminal device 10 compares the received request information and / or reservation information with its own request and / or reservation, and determines that it corresponds to its own request and / or reservation when they match (step S302). . When step S302 is Yes, the terminal device 10 determines that the received key ID of the vehicle 40 is addressed to itself (step S303). When step S302 is No, the terminal device 10 determines that the received key ID of the vehicle 40 is not addressed to itself (step S304). When it is determined that the key ID of the received vehicle 40 is not addressed to itself (in the case of step S304), the received key ID of the vehicle 40 is preferably discarded.

  In the car sharing system to be described, the terminal device 10 may not be essential. For example, the server 10 and the electronic key 30 may communicate directly. In addition, when the server 10 and the electronic key 30 communicate directly, it is preferable that the electronic key 30 is provided with a part or all of the function of the terminal device 10.

(Configuration of electronic key 30)

  The communication unit 31 receives the key ID of the vehicle 40 transmitted from the communication unit 24. The memory 32 stores the key ID of the vehicle 40 received by the communication unit 31. The control unit 33 performs preprocessing for transmitting the received key ID of the vehicle 40 to the vehicle 40. The communication unit 34 transmits the key ID of the vehicle 40 to the vehicle 40.

  Here, the preprocessing for transmitting the key ID of the vehicle 40 to the vehicle 40 in the control unit 33 may be determining a setting related to transmission of the key ID of the vehicle 40. In addition, since the description regarding the transmission of the key ID of the vehicle 40 is the same as the description in the control part 12, it abbreviate | omits. The setting related to the transmission of the key ID of the vehicle 40 used by the control unit 33 may be the same as the setting related to the transmission of the key ID of the vehicle 40 determined by the control unit 12 of the server 10. It may be the same as the setting related to the transmission of the key ID of the vehicle 40 determined in the control unit 23. In this case, the processing load on the control unit 33 can be reduced.

  Here, the state where the key ID of the vehicle 40 is stored in the memory 32 may be referred to as a state where the first authority (function) is given to the electronic key 30. For example, the state in which the key ID of the vehicle 40 is stored in the memory 32 may be referred to as a state in which the authority (function) as the vehicle key of the vehicle 40 is given to the electronic key 30. That is, receiving the key ID of the vehicle 40 from the terminal device 20 by the electronic key 30 may be referred to as giving the first authority (function) to the electronic key 30 by the terminal device 20. That is, receiving the key ID of the vehicle 40 from the terminal device 20 by the electronic key 30 may be referred to as giving the authority (function) as the vehicle key of the vehicle 40 to the electronic key 30 by the terminal device 20. That is, the electronic key 30 is an electronic key that can be given authority (function) as a vehicle key of the vehicle 40. In other words, the electronic key 30 is an electronic key that can be given authority (function) as a vehicle key of any vehicle. In other words, the electronic key 30 is an electronic key that can be given the first authority (function).

  Here, a state in which the key ID of the vehicle 40 is not stored in the memory 32 may be referred to as a state in which the first authority (function) is not given to the electronic key 30. It may be referred to as a state where authority (function) can be granted, or as a state where the second authority (function) is granted to the electronic key 30. For example, a state in which the key ID of the vehicle 40 is not stored in the memory 32 may be referred to as a state in which the authority (function) as the vehicle key of the vehicle 40 is not given to the electronic key 30. For example, the electronic key 30 may be referred to as a state where authority (function) as a vehicle key of the vehicle 40 can be given.

  The memory 32 or the control unit 33 may be referred to as an authorization unit, a part of the memory 32 or the control unit 33 may be referred to as an authorization unit, and the electronic key 30 may be referred to as the memory 32 or the control unit 33. Alternatively, an authority granting unit (not shown) may be provided. In addition, it is preferable that an authority provision part has the function to provide the authority (function) mentioned above. For example, it is preferable that the authority granting part grants the first authority (function) to the electronic key 30. For example, it is preferable that the authority granting part grants the authority (function) as the vehicle key of the vehicle 40 to the electronic key 30.

  Here, the communication used by the communication unit 31 is preferably short-range wireless communication. In other words, the communication between the terminal device 20 and the electronic key 30 is preferably short-range wireless communication.

  Here, it is preferable that the communication unit 34 receives information from the vehicle 40 using a radio signal in the first frequency band and transmits information to the vehicle 40 using a radio signal in the second frequency band. In other words, the communication between the electronic key 30 and the vehicle 40 is preferably communication using the first frequency band and the second frequency band. In other words, the communication between the electronic key 30 and the vehicle 40 is preferably a communication used with a known smart key. Note that the second frequency band is preferably a frequency band different from the first frequency band. That is, the communication used by the communication unit 34 is preferably FDD (Frequency Division Duplex) communication. For example, the first frequency band is an LF (Low Frequency) band, and is a second frequency band UHF (Ultra Hi Frequency) band.

  Further, the second frequency band may be the same frequency band as the first frequency band. That is, the communication used by the communication unit 34 may be TDD (Time Division Duplex) communication.

  In addition, when the communication part 34 receives information from the vehicle 40 using the radio signal of the 1st frequency band, it is preferable to transmit information to the vehicle 40 using the radio signal of the 2nd frequency band. For example, when the communication unit 34 receives information related to the transmission request for the key ID of the vehicle 40 from the vehicle 40 using the radio signal in the first frequency band, the communication unit 34 uses the radio signal in the second frequency band. It is preferable to transmit the key ID of the vehicle 40 to the vehicle. That is, the information related to the transmission request for the key ID of the vehicle 40 is preferably information transmitted from the vehicle 40 to the electronic key 30, and the electronic key 30 that has received the information related to the transmission request for the key ID of the vehicle 40.

The electronic key 30 (communication unit 34) may transmit the key ID of the vehicle 40 to the vehicle 40 when the user holding the electronic key 30 approaches the vehicle 40. For example, the electronic key 30 (communication unit 34) may transmit the key ID of the vehicle 40 to the vehicle 40 when detecting that the electronic key 30 exists within a predetermined distance from the vehicle 40.

  The electronic key 30 is preferably held in advance by a user (user) who uses car sharing. When the user wants to use the first vehicle among a plurality of vehicles, the user assigns the authority as the vehicle key of the first vehicle to the electronic key 30 that is held in advance. It can be used as a vehicle key of a vehicle. As a result, the user can use the first vehicle to be used. In other words, the user can use a plurality of vehicles using one electronic key 30. In other words, the electronic key 30 is an electronic key that can be used in common by a plurality of vehicles. In other words, the electronic key 30 is an electronic key shared by a plurality of vehicles. In other words, the electronic key 30 is an electronic key that can be used in common by a plurality of vehicles held in advance by a user. In other words, the electronic key 30 is an electronic key shared by a plurality of vehicles that is held in advance by the user. Note that “preliminarily held” means that one is assigned to each user who uses car sharing.

  An operation when the electronic key 30 belongs to any group (for example, when a group ID is assigned to the electronic key 30) will be described. When the electronic key 30 belongs to any group, the electronic key 30 transmits the group ID together with the key ID of the vehicle 40 to the vehicle 40.

  The electronic key 30 is preferably assigned a group ID in advance. For example, the group ID of the electronic key 30 may be set when the electronic key 30 is shipped from the factory, may be set by the seller of the electronic key 30, or may be set by the provider of the car sharing service.

  By using the electronic key 30, a facility for storing the electronic key such as a key box becomes unnecessary, and a car sharing system with a low manufacturing cost can be provided. In addition, by using the electronic key 30, the user can get on various vehicles using one electronic key, so that convenience for the user is improved. Further, by using the electronic key 30, it is not necessary to take out the electronic key from a facility for storing the electronic key such as a key box, so that convenience for the user is improved. Further, in the car sharing system using the conventional key box, there is a problem that other users cannot use the vehicle when the user accidentally brings back the electronic key. However, the problem is solved when the user holds the electronic key 30 in advance.

(Configuration of vehicle 40)
The vehicle 40 performs wireless communication with the electronic key 30.

  The vehicle 40 includes a communication unit 41, a memory 42, and a control unit 43. Although not shown, the control unit 43 is preferably connected to at least the communication unit 41 and the memory 42 by wired connection or wireless connection. Note that at least the communication unit 41 and the memory 42 are preferably controlled by the control unit 43. The control unit 43 may be referred to as an electronic control unit (ECU, Electronic Control Unit). The communication unit 41, the memory 42, and the control unit 43 may be referred to as an ECU. Moreover, the control part 43 may control the apparatus (For example, the apparatus regarding a door lock, the apparatus regarding an ignition lock, etc.) for making the vehicle 40 a usable state.

  The communication unit 41 receives the key ID of the vehicle 40 transmitted from the communication unit 34. The memory 42 stores the key ID of the vehicle 40 received by the communication unit 41. The control unit 43 collates the key ID of the vehicle 40 received via the communication unit 41 with the key ID held in advance by the vehicle 40. When the verification is established, the control unit 43 puts the vehicle 40 into a usable state.

  Here, the key ID held in advance by the vehicle 40 is preferably a key ID for collating the key ID of the vehicle 40 received via the communication unit 41. For example, the key ID previously held by the vehicle 40 is preferably a key ID stored (set) in the memory 42 in advance. The key ID stored (set) in advance in the memory 42 may be a key ID set when the vehicle 40 is shipped from the factory, or may be a key ID set by the seller of the vehicle 40. It may be a key ID set by a provider of a car sharing service using the vehicle 40. In addition, when the vehicle 40 has a function of communicating with an external device such as the server 10, a key ID for collation may be received from the external device and stored, set, and / or updated in the memory 42.

  Here, “check key ID” means whether or not the key ID of the vehicle 40 received via the communication unit 41 matches the key ID held in advance by the vehicle 40. It is to confirm whether or not the key ID of the vehicle 40 is correct.

  FIG. 4 shows an example of a key ID verification flow. 4 may be started when the vehicle 40 receives the key ID of the vehicle 40, or may be started when the user operates the electronic key 30. It may be started periodically, or may be started when the vehicle 40 makes a transmission request for the key ID of the vehicle 40 to the electronic key 30. The vehicle 40 receives the key ID of the vehicle 40 (step S401). The vehicle 40 collates the key ID of the vehicle 40 received in step S401 with the key ID held in advance by the vehicle 40 (step S402). If step S402 is Yes, the vehicle 40 determines that the key ID of the vehicle 40 received in step S401 is correct (step S403). Then, the vehicle 40 is made available (step S404). When step S402 is No, the vehicle 40 determines that the key ID of the vehicle 40 received in step S401 is not correct (step S405). The vehicle 40 determines that the key ID of the vehicle 40 received in step S401 is not correct (in the case of step S405), and the received key ID of the vehicle 40 is preferably discarded. That is, the vehicle 40 can be said to be in a usable state when receiving the correct key ID of the vehicle 40 from the electronic key 30. Further, when the vehicle 40 receives an incorrect key ID of the vehicle 40 from the electronic key 30, it can be said that the vehicle 40 is not in a usable state.

  An operation when the vehicle 40 belongs to any group (for example, when a group ID is received from the server 10) will be described. Even if it is determined that the received key ID of the vehicle 40 is correct based on the key ID verification flow of FIG. 4, the key ID is received from the electronic key 30 belonging to a group different from the group to which the vehicle 40 belongs. If it is, the received key ID of the vehicle 40 is determined to be incorrect. The group ID verification flow is preferably the same as the key ID verification flow in FIG. That is, the “key ID” in FIG. 4 may be rephrased as “group ID” as appropriate. Then, the vehicle 40 is not made available. For example, the vehicle 40 may determine whether or not the group to which the electronic key 30 belongs is the same as itself by receiving the group ID together with the key ID from the electronic key 30.

  That is, the vehicle 40 determines whether or not the group ID and key ID received from the electronic key 30 match the group ID and key ID stored in the vehicle 40. May be in a usable state.

  Here, “to make the vehicle 40 usable” means to permit the vehicle 40 to get on, to release the lock of the vehicle 40, to make the vehicle 40 ready to run, and to lock the door of the vehicle 40. , Release the ignition lock of the vehicle 40, turn on the power of the vehicle 40, permit the start of the engine of the vehicle 40, permit the start of the motor of the vehicle 40, It is preferable that a part or all of permitting use of the device, enabling use of the in-vehicle device of the vehicle 40, and allowing the user to access the vehicle 40 are included.

  The communication unit 41 preferably transmits information to the electronic key 30 using a radio signal in the first frequency band and receives information from the electronic key 30 using a radio signal in the second frequency band. In other words, the communication between the electronic key 30 and the vehicle 40 is preferably communication using the first frequency band and the second frequency band. In other words, the communication between the electronic key 30 and the vehicle 40 is preferably a communication used with a known smart key.

  The communication unit 41 may receive information from the electronic key 30 using the radio signal in the second frequency band when the information is transmitted to the electronic key 30 using the radio signal in the first frequency band. preferable. For example, when the communication unit 41 transmits information related to the transmission request for the key ID of the vehicle 40 to the electronic key 30 using the wireless signal in the first frequency band, the communication unit 41 electronically uses the wireless signal in the second frequency band. It is preferable to receive the key ID of the vehicle 40 from the key 30. That is, the information related to the transmission request for the key ID of the vehicle 40 is information transmitted from the vehicle 40 to the electronic key 30, and the electronic key 30 that has received the information related to the transmission request for the key ID of the vehicle 40 is The key ID of the vehicle 40 is transmitted to 40. Note that the vehicle 40 (communication unit 41) may transmit information related to the transmission request for the key ID of the vehicle 40 to the electronic key 30 when the user holding the electronic key 30 approaches the vehicle 40. For example, when the vehicle 40 (communication unit 41) detects that the electronic key 30 exists within a predetermined distance from the vehicle 40, the vehicle 40 (communication unit 41) transmits information related to the transmission request for the key ID of the vehicle 40 to the electronic key 30. Also good.

  Note that the key ID of the vehicle 40 may be converted in any of the server 10, the terminal device 20, the electronic key 30, and the vehicle 40. For example, the key ID of the vehicle 40 may be transmitted to the electronic key 30 after being converted by the control unit 23 of the terminal device 20. In other words, the key ID of the vehicle 40 may be transmitted to the electronic key 30 after being converted for the electronic key 30 in the control unit 23 of the terminal device 20. For example, the key ID of the vehicle 40 may be transmitted to the vehicle 40 after being converted by the control unit 33 of the electronic key 30. In other words, the key ID of the vehicle 40 may be transmitted to the vehicle 40 after being converted for the vehicle 40 by the control unit 33 of the electronic key 30. Note that the conversion mechanism is preferably known in the server 10, the terminal device 20, the electronic key 30, and the vehicle 40. For example, when the vehicle 40 receives the key ID converted in the electronic key 30, the vehicle 40 resolves the key ID conversion based on a known conversion mechanism, and then stores the received key ID and the previously held key. You may collate with ID. For example, when the vehicle 40 receives the key ID converted by the electronic key 30, the vehicle 40 converts the key ID held in advance based on a known conversion mechanism and then holds the received key ID in advance. The key ID may be collated. In addition, “the key ID of the vehicle 40 being converted” may be paraphrased as the generation of information based on the key ID of the vehicle 40.

  As described above, direct communication between the vehicle 40 and the terminal device 20 may be unnecessary. For example, the vehicle 40 may have only a communication function with a conventional electronic key. Since the vehicle 40 does not communicate with the terminal device 20, the vehicle 40 does not need to be equipped with a communication unit (communication module) for directly communicating between the vehicle 40 and the terminal device 20. / Or the cost of remodeling the vehicle 40 is reduced. Moreover, security is improved by not communicating directly between the vehicle 40 and the terminal device 20. Moreover, since the key box for storing the electronic key for exclusive use of a vehicle like the prior art may be unnecessary, the manufacturing cost of the vehicle 40 and / or the modification cost of the vehicle 40 fall. Further, when it is possible to get into the vehicle using a smartphone or the like instead of the electronic key, the conventional take-out alarm does not act (for example, the user may misplace the smartphone instead of the electronic key in the vehicle). However, the conventional take-out alarm can be continuously used by using the electronic key 30.

  That is, the described car sharing system is a car sharing system that is possessed by a server and a user, and includes an electronic key to which a group ID is assigned in advance, and a vehicle. The group ID is assigned to the vehicle based on a request from an administrator of the vehicle, the server assigns the vehicle to the user based on the user's reservation request, and the user accesses the vehicle. The server generates a key ID for enabling the server, the server transmits the generated key ID to the electronic key, and transmits the generated key ID to the vehicle. Is detected within a predetermined distance from the vehicle, a transmission request is transmitted to the electronic key, and the transmission request is The transmitted electronic key transmits the group ID and the key ID to the vehicle, and the vehicle stores the group ID and the key ID received from the electronic key in the vehicle. It is a car sharing system that determines whether or not an ID matches a key ID, and permits access to the vehicle by the user when it is determined to match.
