Summary of the Invention

Problems to be Solved by the Invention

[0004] The remote immobilizer disclosed in the above background art is a function that allows a user to remotely set an immobilizer from a user terminal. If it is previously set via the user terminal to set the immobilizer every time the vehicle's IG power supply is turned off, the remote immobilizer will be set every time the IG power supply is turned off. Therefore, when a user who is the owner of the vehicle lends the vehicle to another person (for example, a family member, etc.), there is a risk that the immobilizer will be set during the borrowing period, and the borrower may not be able to start the engine while moving. This reduces the convenience for the borrower. Although the remote immobilizer can be released from the vehicle's navigation screen, sharing the PIN code known only to the owner with the borrower will result in a reduction in security. Thus, the above background art has problems in releasing the remote immobilizer by the borrower of the vehicle. That is, there is insufficient consideration for the trade-off between strengthening security for theft prevention and the convenience of the borrower who has borrowed the vehicle.

[0005] In view of such circumstances, an object of the present disclosure is to ensure the convenience of the borrower of the vehicle while strengthening the security for theft prevention.

Means for Solving the Problems

[0006] A vehicle according to one embodiment of this disclosure is A vehicle including a DCM and a matching ECU, wherein the DCM is If it is determined that the vehicle is on loan, a remote immobilizer setting request is not sent to the matching ECU, even if the vehicle's ignition power is off. [Effects of the Invention]

[0007] According to one embodiment of the present disclosure, it is possible to ensure the convenience of the vehicle borrower while enhancing security to prevent theft. [Brief explanation of the drawing]

[0008] [Figure 1] This is a schematic diagram of the information processing system of this embodiment. [Figure 2] This is a sequence diagram illustrating the operation of an information processing system. [Modes for carrying out the invention]

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

[0011] The information processing device 1 may be a server that supports the provision of services by a service provider. The information processing device 1 may be installed, for example, in a facility exclusively for the service provider, or in a shared facility including a data center. Alternatively, the information processing device 1 may be mounted on a vehicle 2.

[0012] Vehicle 2 includes any type of automobile, such as a gasoline car, diesel car, HEV, PHEV, BEV, or 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 Vehicle 2 may be automated to any level. The level of automation may be, for example, one of levels 1 to 5 in the SAE classification. "SAE" is an abbreviation for Society of Automotive Engineers. Vehicle 2 may also be a vehicle dedicated to MaaS. "MaaS" is an abbreviation for Mobility as a Service. As an alternative, Vehicle 2 may be driven by a driver.

[0013] Vehicle 2 includes a DCM 21 (Data Communication Module 21), a matching ECU 22, a navigation system 23, a body 24, facial recognition 25, and an alarm 26. Each component of Vehicle 2 is connected to communicate with one another.

[0014] User terminal 3 is operated by the owner of vehicle 2. User terminal 3 is a mobile device such as a cell phone, smartphone, wearable device, or tablet. Alternatively, 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. Each component of the information processing device 1 is connected to each other in a way that allows for communication.

[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 processors, the control unit 11 may include one or more dedicated circuits. The dedicated circuits may be, for example, an FPGA (Field-Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit). The control unit 11 may also include an ECU (Electronic Control Unit). The control unit 11 sends and receives arbitrary information via the communication unit 12.

The communication unit 12 transmits and receives arbitrary information via the network.

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

[0019] The schematic configuration of this embodiment will be described. The user terminal 3 shown in FIG. 1 is a terminal for setting a remote immobilizer. The information processing apparatus 1 transmits the remote immobilizer command from the user terminal 3 to the DCM 21. The DCM 21 receives the command from the information processing apparatus 1 and decodes the remote immobilizer command. The DCM 21 determines whether to issue a remote immobilizer setting request to the collation ECU 22 each time the IG power supply of the vehicle 2 is turned off. The collation ECU 22 sets the remote immobilizer of the vehicle 2 according to the remote immobilizer setting request from the DCM 21. The navigation 23 receives the remote immobilizer setting of the collation ECU 22 and displays a remote immobilizer cancellation screen when the next IG power supply is turned on. The face authentication 25 can identify the owner of the vehicle 2 by face authentication as a device of the collation ECU 22. The body 24 is an ECU that detects an alarm during theft and notifies the DCM 21.

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

[0021] In this embodiment, the owner P1 of the vehicle 2 lends the vehicle 2 to another person (here, the borrower P2). Here, for the sake of comparison, the normal case where the owner P1 does not lend the vehicle 2 and the case during borrowing where the owner P1 lends the vehicle 2 to the borrower P2 are explained for the sake of comparison.

[0022] The normal case is explained. At S1, the user terminal 3 receives a remote immobilization request from the owner P1 and transmits it to the DCM21. At S2, the DCM21 receives the remote immobilization request. At S3, the ignition power supply of the vehicle 2 is turned off by the user operation. At S4, when the DCM21 detects the turn-off of the ignition power supply, it transmits a remote immobilization setting request to the collation ECU22 and the navigation 23. At S5, the collation ECU22 sets the remote immobilization. At S6, the ignition power supply is turned on. At S7, the navigation 23 displays a remote immobilization cancellation screen. At S8, when the navigation 23 receives the input of the PIN code from the owner P1, it transmits a remote immobilization cancellation request to the collation ECU22. At S9, the collation ECU22 cancels the remote immobilization.

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

[0024] At S12, the DCM21 sets the GDM mode. At S13, the ignition power supply is turned off. At S14, the DCM21 detects the turn-off of the ignition power supply.

[0025] At S15, the DCM21 determines whether the GDM mode is set, that is, whether the vehicle 2 is lent out. As an additional example or an alternative example, the DCM21 may determine that the vehicle 2 is lent out in any of the following cases. 1. The collation ECU22 determines the user of the smart key. When the DCM21 receives the result and determines that the user is a registered user other than the owner P1. 2. Navi 23 identifies the user from the connected device via Bluetooth (registered trademark). DCM21 receives the result and determines that the user is a registered user other than owner P1. 3. The matching ECU22 identifies the user based on the facial recognition result. The DCM21 receives the result and determines that the user is a registered user other than owner P1. 4. When valet mode (security deactivation) is set by user instruction via user terminal 3 or navigation 23, and the DCM21 receives the result.

[0026] If the answer to S15 is Yes, DCM21 determines that vehicle 2 is on loan and terminates the flow. In this case, DCM21 does not perform remote immobilizer setup. Alternatively, even if DCM21 receives a remote immobilizer setup request from information processing device 1, it rejects it and notifies information processing device 1 of the rejection. However, if DCM21 detects that an alarm has been triggered and theft has occurred, it may enable remote immobilizer setup even while the above GDM mode is being set.

[0027] If the answer in S15 is No, the DCM21 sends a remote immobilizer setting request to the matching ECU22 and the navigation system 23. In S16, the matching ECU22 sets the remote immobilizer. The processing after setting the remote immobilizer has already been explained in the normal case above, so a further explanation is omitted here.

[0028] As described above, according to this embodiment, when the DCM21 determines that vehicle 2 is being rented, it does not send a remote immobilizer setting request to the matching ECU22 even if the ignition power of vehicle 2 is off. This configuration allows vehicle 2 to enhance security against theft while ensuring convenience for the borrower of vehicle 2.

[0029] While this disclosure is described based on drawings and embodiments, it should be noted that those skilled in the art may make various modifications and alterations based on this disclosure. Furthermore, changes are permitted as long as they do not depart from the spirit of this disclosure. For example, the functions included in each means or step can be rearranged in a logically consistent manner, and multiple means or steps can be combined into one or divided.

[0030] For example, in the above embodiment, a program that performs all or part of the functions or processing of the information processing device 1 or the vehicle 2 can be recorded on a computer-readable recording medium. The computer-readable recording medium includes non-temporary computer-readable media, such as a magnetic recording device, optical disc, magneto-optical recording medium, or semiconductor memory. The program can be distributed, for example, by selling, transferring, or lending a portable recording medium such as a DVD (Digital Versatile Disc) or CD-ROM (Compact Disc Read Only Memory) on which the program is recorded. Alternatively, the program can be distributed by storing it in the storage of any server and transmitting the program from any server to another computer. The program can also be provided as a program product. This disclosure can also be implemented as a program that can be executed by a processor. [Explanation of Symbols]
