Description

[Technical field]

[0001] The present disclosure relates to vehicles. [Background technology]

[0002] 2. Description of the Related Art Conventionally, there is known a technique for remotely prohibiting the driving of a vehicle engine or the like (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2007-253818 A Summary of the Invention [Problem to be solved by the invention]

[0004] The remote immobilizer disclosed in the background art is a function that allows a user to remotely set an immobilizer from a user terminal. If the user terminal is set in advance to set the immobilizer every time the IG power supply of the vehicle is turned off, the remote immobilizer is set every time the IG power supply is turned off. Therefore, if a user who is the owner of a vehicle lends the vehicle to another person (e.g., a family member, etc.), there is a risk that the immobilizer will be set during the loan, and the borrower will not be able to start the engine while traveling. This reduces the convenience of the borrower. The remote immobilizer can also be deactivated from the navigation screen of the vehicle, but security is reduced because a PIN code that only the owner knows is shared with the borrower. Thus, the background art has a problem when a borrower of a vehicle deactivates the remote immobilizer. In other words, there is insufficient consideration of the trade-off between strengthening security to prevent theft and convenience of the borrower who borrows the vehicle.

[0005] The objective of the present disclosure, made in consideration of the above circumstances, is to ensure convenience for vehicle renters while strengthening security against theft. [Means for solving the problem]

[0006] A vehicle according to an embodiment of the present disclosure includes: A vehicle including a DCM and a verification ECU, When it is determined that the vehicle is rented out, a request for setting a remote immobilizer is not transmitted to the verification ECU even if the IG power supply of the vehicle is turned off. Effect of the Invention

[0007] According to one embodiment of the present disclosure, it is possible to ensure convenience for vehicle renters while strengthening security against theft. [Brief description of the drawings]

[0008] [Figure 1] 1 is a schematic diagram of an information processing system according to an embodiment of the present invention. [Diagram 2] FIG. 2 is a sequence diagram showing an operation of the information processing system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] 1 is a schematic diagram of an information processing system S according to the present embodiment. The information processing system S includes an information processing device 1, a vehicle 2, and a user terminal 3 that are capable of communicating with each other via a network NW. The network NW includes, for example, a mobile communication network, the Internet, or a fixed communication network.

[0010] For ease of explanation, FIG. 1 illustrates one each of information processing devices 1, vehicles 2, and user terminals 3. However, the respective numbers of information processing devices 1, vehicles 2, and user terminals 3 are not limited to this. For example, the processing executed by the information processing device 1 may be executed by multiple information processing devices 1 that are distributed.

[0011] The information processing device 1 may be a server that supports the provision of services by a business operator. The information processing device 1 may be installed, for example, in a facility dedicated to the business operator or in a shared facility including a data center. As an alternative example, the information processing device 1 may be mounted on a vehicle 2.

[0012] The vehicle 2 includes any type of automobile, such as, for example, a gasoline vehicle, a diesel vehicle, an HEV, a PHEV, a BEV, or an FCEV. "HEV" is an abbreviation for hybrid electric vehicle. "PHEV" is an abbreviation for plug-in hybrid electric vehicle. "BEV" is an abbreviation for battery electric vehicle. "FCEV" is an abbreviation for fuel cell electric vehicle. The operation of the vehicle 2 may be automated at any level. The level of automation may be, for example, any of levels 1 to 5 in the SAE level classification. "SAE" is an abbreviation for Society of Automotive Engineers. The vehicle 2 may be a MaaS-only vehicle. "MaaS" is an abbreviation for Mobility as a Service. As an alternative, the vehicle 2 may be driven by a driver.

[0013] The vehicle 2 includes a DCM 21 (Data Communication Module), a verification ECU 22, a navigation system 23, a body 24, a face recognition system 25, and an alarm 26. The components of the vehicle 2 are connected to each other so as to be able to communicate with each other.

[0014] The user terminal 3 is operated by a person who owns the vehicle 2 (i.e., the owner). The user terminal 3 is, for example, a mobile device such as a mobile phone, a smartphone, a wearable device, or a tablet. Alternatively, the user terminal 3 may be a general-purpose device such as a PC, or a dedicated device. "PC" is an abbreviation for personal computer.

[0015] The information processing device 1 includes a control unit 11, a communication unit 12, and a storage unit 13. The components of the information processing device 1 are connected to each other so as to be able to communicate with each other.

[0016] The control unit 11 includes, for example, one or more general-purpose processors including a CPU (Central Processing Unit) or an MPU (Micro Processing Unit). The control unit 11 may include one or more dedicated processors specialized for specific processing. Instead of including a processor, the control unit 11 may include one or more dedicated circuits. The dedicated circuits may be, for example, a FPGA (Field-Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). The control unit 11 may include an ECU (Electronic Control Unit). The control unit 11 transmits and receives any information via the communication unit 12.

[0017] The communication unit 12 includes a communication module compatible with one or more wired or wireless LAN (Local Area Network) standards for connecting to a network. The communication unit 12 may include a module compatible with one or more mobile communication standards including LTE (Long Term Evolution), 4G (4th Generation), or 5G (5th Generation). The communication unit 12 may include a communication module compatible with one or more short-range communication standards or specifications including Bluetooth (registered trademark), AirDrop (registered trademark), IrDA, ZigBee (registered trademark), Felica (registered trademark), or RFID. The communication unit 12 transmits and receives any information via the network.

[0018] The memory unit 13 includes, but is not limited to, for example, a semiconductor memory, a magnetic memory, an optical memory, or a combination of at least two of these. The semiconductor memory is, for example, a RAM or a ROM. The RAM is, for example, an SRAM or a DRAM. The ROM is, for example, an EEPROM. The memory unit 13 may function as, for example, a main memory device, an auxiliary memory device, or a cache memory. The memory unit 13 may store information resulting from analysis or processing by the control unit 11. The memory unit 13 may store various information related to the operation or control of the information processing device 1, etc. The memory unit 13 may store system programs, application programs, embedded software, etc. The memory unit 13 may be provided outside the information processing device 1 and accessed by the information processing device 1.

[0019] A schematic configuration of the present embodiment will be described. The user terminal 3 shown in FIG. 1 is a terminal for setting the remote immobilizer. The information processing device 1 transmits a remote immobilizer command from the user terminal 3 to the DCM 21. The DCM 21 receives the command from the information processing device 1 and decodes the remote immobilizer command. The DCM 21 judges whether or not to issue a remote immobilizer setting request to the verification ECU 22 each time the IG power supply of the vehicle 2 is turned off. The verification ECU 22 sets the remote immobilizer of the vehicle 2 in accordance with the remote immobilizer setting request from the DCM 21. The navigation system 23 receives the remote immobilizer setting of the verification ECU 22 and displays a remote immobilizer release screen the next time the IG power supply is turned on. The face recognition 25, as a device of the verification ECU 22, can identify the owner of the vehicle 2 by face recognition. The body 24 is an ECU that detects an alarm in the event of theft and notifies the DCM 21.

[0020] In FIG. 2, an information processing method executed in the information processing system S of this embodiment will be described in detail.

[0021] In this embodiment, an owner P1 of a vehicle 2 lends the vehicle 2 to another person (here, a borrower P2). For comparison, a normal case in which the owner P1 does not lend the vehicle 2 and a borrowed case in which the owner P1 lends the vehicle 2 to the borrower P2 will be described here.

[0022] A normal case will be described. At S1, the user terminal 3 accepts a remote immobilization request from the owner P1 and transmits it to the DCM 21. At S2, the DCM 21 receives the remote immobilization request. At S3, the IG power supply of the vehicle 2 is turned off by user operation. At S4, when the DCM 21 detects that the IG power supply is off, it transmits a remote immobilization setting request to the verification ECU 22 and the navigation system 23. At S5, the verification ECU 22 sets the remote immobilization. At S6, the IG power supply is turned on. At S7, the navigation system 23 displays a remote immobilization release screen. At S8, the navigation system 23 accepts input of a PIN code from the owner P1 and transmits a remote immobilization release request to the verification ECU 22. At S9, the verification ECU 22 releases the remote immobilization.

[0023] The case of borrowing will be described. In S11, the user terminal 3 of the owner P1 requests the setting of a GDM (Guest Driver Monitor) mode. The GDM mode is a mode that is set when the owner P1 lends the vehicle 2 to the borrower P2.

[0024] In S12, the DCM 21 sets the GDM mode. In S13, the IG power supply is turned off. In S14, the DCM 21 detects that the IG power supply is turned off.

[0025] In S15, the DCM 21 determines whether the GDM mode is set, i.e., whether the vehicle 2 is rented out. Additionally or alternatively, the DCM 21 may determine that the vehicle 2 is rented out in any of the following cases: 1. The verification ECU 22 identifies the user of the smart key. The DCM 21 receives the result and determines that the user is a registered user other than the owner P1. 2. The navigation system 23 determines the user from the terminal connected via Bluetooth (registered trademark). The DCM 21 receives the result and determines that the user is a registered user other than the owner P1. 3. The verification ECU 22 identifies the user based on the result of face authentication. The DCM 21 receives the result and determines that the user is a registered user other than the owner P1. 4. When valet mode (security deactivation) is set by user instruction via the user terminal 3 or navigation system 23, and the result is received by the DCM 21.

[0026] If the answer is Yes in S15, the DCM 21 determines that the vehicle 2 is rented out and ends the flow. In this case, the DCM 21 does not set the remote immobilizer. As an alternative, the DCM 21 may reject a request to set the remote immobilizer even if it has been received from the information processing device 1, and notify the information processing device 1 of the rejection. However, if an alarm report is generated and a theft is detected, the DCM 21 may enable the remote immobilizer setting even when the GDM mode is set.

[0027] If the result in S15 is No, the DCM 21 transmits a request to set the remote immobilizer to the verification ECU 22 and the navigation system 23. In S16, the verification ECU 22 sets the remote immobilizer. The process after the remote immobilizer is set has been described in the normal case above, so that a description thereof will not be repeated here.

[0028] As described above, according to this embodiment, when the DCM 21 determines that the vehicle 2 is rented out, it does not transmit a remote immobilizer setting request to the verification ECU 22 even if the IG power supply of the vehicle 2 is off. With this configuration, the vehicle 2 can ensure the convenience of the borrower of the vehicle 2 while strengthening the security against theft.

[0029] Although the present disclosure will be described based on various drawings and examples, it should be noted that those skilled in the art may make various modifications and alterations based on the present disclosure. Other modifications are possible within the scope of the present disclosure. For example, the functions included in each means or step can be rearranged so as not to cause logical inconsistencies, and multiple means or steps can be combined into one or divided.

[0030] For example, in the above embodiment, a program for executing all or part of the functions or processes of the information processing device 1 or the vehicle 2 can be recorded in a computer-readable recording medium. The computer-readable recording medium includes a non-transitory computer-readable medium, for example, a magnetic recording device, an optical disk, a magneto-optical recording medium, or a semiconductor memory. The program is distributed, for example, by selling, transferring, or lending a portable recording medium such as a DVD (Digital Versatile Disc) or a CD-ROM (Compact Disc Read Only Memory) on which the program is recorded. The program may also be distributed by storing the program in the storage of an arbitrary server and transmitting the program from the arbitrary server to another computer. The program may also be provided as a program product. The present disclosure can also be realized as a program executable by a processor. [Explanation of symbols]
