Description

[Technical field]

[0001] The present invention relates to a vehicle, an information processing device, a parking assistance method, an information processing method, and a program. [Background technology]

[0002] In recent years, parking assistance devices have been developed that allow a vehicle to be parked in a specified position by operating a remote terminal from outside the vehicle. In such parking assistance devices, it is considered that the operator of the remote terminal operates an electronic key, and parking assistance operations are accepted on the condition that user authentication is performed using the electronic key.

[0003] In this case, the user is required to operate the electronic key every time he or she performs a parking assistance operation, which causes the operation to be complicated.

[0004] On the other hand, a parking assistance device has been proposed that, when accepting parking assistance operations from a mobile terminal, it identifies the area in which the mobile terminal is located in relation to the vehicle, and if there is only one electronic key present within that area, it identifies and authenticates the operator's electronic key, enabling parking assistance operations to be performed (see Patent Document 1). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-32895 A Summary of the Invention [Problem to be solved by the invention]

[0006] In the above prior art, whether or not the user has the electronic key for the vehicle is determined based on whether the area where the mobile device is located matches the area where the electronic key is located. This eliminates the need for the user to operate the electronic key every time they perform parking assistance operations on the mobile device, making parking assistance operations easier.

[0007] However, if multiple users each having different electronic keys for the vehicle are located close to each other in the same area, there is a risk that the vehicle will not be able to determine which electronic key belongs to the user performing the parking assistance operation.

[0008] In other words, it is desirable to eliminate the need for the user to operate an electronic key when performing a parking assistance operation, and to be able to reliably authenticate the user performing the parking assistance operation.

[0009] In consideration of the above, the present invention aims to provide a vehicle, an information processing device, a parking assistance method, an information processing method, and a program that can reliably authenticate a user while eliminating the need for a user to operate an electronic key when performing parking assistance operations. [Means for solving the problem]

[0010] The vehicle of the first aspect includes a first acquisition unit that acquires information of a mobile device on which an operation has been performed to perform parking assistance for the vehicle, a determination unit that determines whether a first electronic key of the vehicle associated with the mobile device has been detected outside the vehicle within a predetermined range from the vehicle, and a control unit that, when the determination unit determines that the first electronic key has been detected, transitions the mobile device to a state in which it can accept parking assistance operations, and, when the determination unit determines that the first electronic key has not been detected, transitions the mobile device to a state in which it can accept parking assistance operations on the condition that operation of a second electronic key of the vehicle different from the first electronic key is detected.

[0011] In this vehicle, a first acquisition unit acquires information on a mobile device on which an operation for performing parking assistance for the vehicle has been performed. Next, a determination unit determines whether or not a first electronic key for the vehicle associated with the mobile device has been detected outside the vehicle within a predetermined range from the vehicle. Next, when the determination unit detects the first electronic key outside the vehicle within a predetermined range from the vehicle, the control unit transitions to a state in which it can accept parking assistance operations from the mobile device.

[0012] On the other hand, if the determination unit does not detect the first electronic key outside the vehicle within a specified range from the vehicle, it transitions to a state in which it can accept parking assistance operations from the mobile terminal, provided that it detects operation of a second electronic key of the vehicle that is different from the first electronic key.

[0013] In other words, in this vehicle, when a first electronic key associated with a mobile terminal is detected within a specified range from the vehicle, the vehicle's (control unit) determines that the user performing parking assistance operations on the mobile terminal is in possession of the first electronic key (user authentication), and makes it possible to accept parking assistance operations from the mobile terminal.

[0014] Even if the first electronic key is not detected within a predetermined range from the vehicle, the user may have brought a second electronic key other than the first electronic key. In this case, the vehicle (control unit) determines that the user performing the parking assistance operation is carrying the second electronic key (user authentication) on the condition that the operation of the second electronic key is detected, and makes it possible to accept parking assistance operations from a mobile terminal.

[0015] In other words, by previously associating the vehicle user's mobile terminal with the first electronic key, when the user operates the parking assistance function on the mobile terminal, the user can perform the parking assistance function simply by carrying the first electronic key (without operating it).

[0016] Even if the user has a second electronic key that is different from the first electronic key that is pre-associated with the mobile terminal, parking assistance operations can be performed from the mobile terminal by operating the second electronic key.

[0017] Incidentally, "detecting the operation of the second electronic key" means detecting an operation signal from the second electronic key in the vehicle and detecting a vehicle operation based on the operation signal, such as a wireless unlocking operation of the door lock. In addition, an "operation for performing parking assistance for a vehicle" refers to, for example, starting up a parking assistance app on a mobile terminal or inputting an operation start command for a parking assistance operation.

[0018] The vehicle of the second aspect is the vehicle of the first aspect, further comprising a key operation detection unit that detects operation of the second electronic key, and if the first electronic key is not detected by the determination unit and the key operation detection unit does not detect operation of the second electronic key, the control unit does not transition to a state capable of accepting the parking assistance operation.

[0019] In this vehicle, if the determination unit cannot detect a first electronic key associated with a mobile terminal outside the vehicle within a specified range from the vehicle, and the key operation detection unit does not detect operation of a second electronic key, which is an electronic key for the vehicle other than the first electronic key, the control unit does not transition to a state capable of accepting parking assistance operations.

[0020] That is, the vehicle determines that the user performing the parking assist operation cannot be authenticated, and stops accepting (deems unacceptable) the parking assist operation.

[0021] A vehicle according to a third aspect further includes a first transmission unit that transmits an operation request signal for the second electronic key to the mobile terminal when the determination unit does not detect the first electronic key in the vehicle according to the first or second aspect.

[0022] In this vehicle, if the determination unit cannot detect a first electronic key that is pre-associated with the mobile terminal within a specified range from the vehicle outside the vehicle, the first transmission unit transmits an operation request signal to the mobile terminal to prompt the user performing the parking assistance operation to operate a second electronic key that is different from the first electronic key.

[0023] When the mobile terminal receives this operation request signal, it notifies the user of the operation request, for example, by displaying a screen that prompts the user to operate the (second) electronic key. As a result, the user operates the second electronic key, and the operation is detected by the vehicle, which puts the vehicle in a state in which it can accept parking assistance operations. As a result, the user can perform parking assistance operations from the mobile terminal.

[0024] That is, by transmitting an operation request signal for the electronic key to the portable terminal on which the parking assistance operation is performed, the user can be prompted to operate the electronic key via the portable terminal.

[0025] A vehicle according to a fourth aspect includes the relay device according to any one of the first to third aspects, further including a registration unit that registers a correspondence relationship between the first electronic key, the mobile terminal, and the vehicle.

[0026] In this vehicle, the correspondence between the mobile device used by the user, the first electronic key, and the vehicle is registered in the registration unit. For example, by registering the relationship between the mobile device and the corresponding first electronic key in the registration unit of the vehicle, the correspondence between the mobile device and the vehicle in which the registration unit is provided is also registered.

[0027] Therefore, in the vehicle, when information about the mobile device on which an operation for parking assistance was performed is acquired by the first acquisition unit, the determination unit checks the first electronic key associated with the mobile device from the correspondence registered in the registration unit, and determines whether or not the first electronic key can be detected within a specified range from the vehicle outside the vehicle.

[0028] In other words, by registering the correspondence between the mobile device carried (used) by the user and the first electronic key in a registration section in the vehicle, the vehicle can perform parking assistance operations simply by detecting the first electronic key, without the user having to operate the first electronic key.

[0029] An information processing device according to a fifth aspect is an information processing device that can be used for parking assistance operations of a vehicle, and includes: a reception unit that receives operations for parking assistance of the vehicle; a second transmission unit that transmits an operation start signal to the vehicle when the reception unit starts to receive the operation; a second acquisition unit that receives an electronic key operation request signal transmitted from the vehicle when the vehicle that has received the operation start signal cannot detect a first electronic key of the vehicle associated with the information processing device outside the vehicle, or a reception possible signal transmitted from the vehicle when the first electronic key can be detected outside the vehicle and when operation of a second electronic key of the vehicle that is different from the first electronic key is detected after transmitting the electronic key operation request signal; and a display control unit that causes the reception unit to display an operation request screen prompting the user to operate the second electronic key when the second acquisition unit receives the electronic key operation request signal, and causes the reception unit to display an operation screen when the second acquisition unit receives the reception possible signal.

[0030] In this information processing device, the reception unit receives a user operation for parking assistance. When reception of the parking assistance operation starts, the second transmission unit transmits a parking assistance operation start signal to the vehicle.

[0031] The second acquisition unit of the information processing device receives from the vehicle an electronic key operation request signal requesting operation of the electronic key when the vehicle that has received the operation start signal cannot detect the first electronic key associated with the information processing device within a predetermined range from the vehicle outside the vehicle, and receives from the vehicle an acceptance signal accepting a parking assist operation when the vehicle can detect the first electronic key within the predetermined range or detects operation of the second electronic key.

[0032] When the information processing device receives the electronic key operation request signal, the display control unit causes the reception unit to display an operation request screen that prompts the user to operate the electronic key.

[0033] When a user who sees this operation request screen operates the electronic key of the vehicle (a second electronic key different from the first electronic key), the vehicle detects the operation of the second electronic key and can authenticate the user who is performing the parking assistance operation. In other words, even if the user does not have the first electronic key associated with the information processing device, the electronic key operation request screen can be displayed on the reception unit of the information processing device to prompt the user to operate the second electronic key that he or she has.

[0034] In addition, in the information processing device, when the reception possible signal is received, the display control unit causes the reception unit to display an operation screen. Therefore, the user performs parking assistance operation by viewing and operating the operation screen of the reception unit, and parking assistance for the vehicle is executed based on the operation.

[0035] A parking assistance method according to a sixth aspect includes a computer executing a process in which the computer acquires information about a portable device on which an operation for performing parking assistance for a vehicle has been performed, determines whether a first electronic key for the vehicle associated with the portable device has been detected outside the vehicle within a predetermined range of the vehicle, and, if it is determined that the first electronic key has been detected, transitions the portable device to a state in which it can accept parking assistance operation, and, if it is determined that the first electronic key has not been detected, transitions the portable device to a state in which it can accept parking assistance operation on the condition that operation of a second electronic key for the vehicle different from the first electronic key is detected.

[0036] According to this parking assist method, the same advantageous effects as those of the first aspect are achieved.

[0037] In an information processing method according to a seventh aspect, a computer receives an operation for assisting parking of a vehicle, transmits an operation start signal to the vehicle when reception of the operation starts, receives an electronic key operation request signal transmitted from the vehicle when the vehicle that has received the operation start signal cannot detect a first electronic key of the vehicle associated with an information processing device outside the vehicle, or receives an acceptance signal transmitted from the vehicle when the first electronic key can be detected outside the vehicle and when operation of a second electronic key of the vehicle that is different from the first electronic key is detected after transmission of the electronic key operation request signal, and executes processing to display an operation request screen prompting operation of the second electronic key when the electronic key operation request signal is received, and to display an operation screen when the acceptance signal is received.

[0038] According to this information processing method, the same advantageous effects as those of the fifth aspect are achieved.

[0039] A program according to an eighth aspect causes a computer to execute the following process: acquire information about a portable device on which an operation for performing parking assistance for a vehicle has been performed; determine whether a first electronic key for the vehicle associated with the portable device has been detected outside the vehicle within a predetermined range of the vehicle; if it is determined that the first electronic key has been detected, transition the portable device to a state in which it can accept parking assistance operation; and if it is determined that the first electronic key has not been detected, transition the portable device to a state in which it can accept parking assistance operation on the condition that operation of a second electronic key for the vehicle different from the first electronic key is detected.

[0040] By executing this program on a computer, the same effects as those of the first aspect can be achieved.

[0041] A program according to a ninth aspect causes a computer to execute processing to accept an operation for assisting parking of a vehicle, transmit an operation start signal to the vehicle when acceptance of the operation starts, receive an electronic key operation request signal transmitted from the vehicle when the vehicle that has received the operation start signal cannot detect a first electronic key of the vehicle associated with an information processing device outside the vehicle, or receive an acceptance signal transmitted from the vehicle when the first electronic key can be detected outside the vehicle and when operation of a second electronic key of the vehicle that is different from the first electronic key is detected after the transmission of the electronic key operation request signal, and display an operation request screen prompting the user to operate the second electronic key when the electronic key operation request signal is received, and display an operation screen when the acceptance signal is received.

[0042] By executing this program on a computer, the same effects as those of the fifth aspect can be achieved. Effect of the Invention

[0043] This makes it possible to reliably authenticate the user while eliminating the need for the user to operate the parking assistance device with an electronic key. [Brief description of the drawings]

[0045] [Embodiment] A remote parking system for remotely parking a vehicle according to one embodiment will be described with reference to the drawings.

[0046] As shown in FIG. 1, the remote parking system 10 includes a vehicle 12, a smartphone 14 that is normally used (carried) by a user, and an electronic key 16 that is normally used (carried) by the user.

[0047] The smartphone 14 corresponds to an "information processing device, mobile terminal."

[0048] Furthermore, when it is necessary to distinguish between the multiple smartphones 14 and the multiple electronic keys 16, they will be referred to as smartphones 14α, 14β and electronic keys 16α, 16β, respectively.

[0049] The vehicle 12 has a clearance sonar ECU (hereinafter referred to as the "clear sonar ECU") 20 that performs remote parking control based on remote parking operation signals from the smartphone 14, a verification ECU 22 that performs verification (user authentication) between the user's smartphone 14 and the electronic key 16 when remote parking begins, and a display control unit (hereinafter referred to as the "DCU") 24 that transmits and receives operation signals to and from the smartphone 14.

[0050] First, the hardware configuration of the checksonator ECU 20 will be described with reference to FIG.

[0051] The Cleansona ECU 20 includes a CPU (Central Processing Unit: processor) 20A, a ROM (Read Only Memory) 20B, a RAM (Random Access Memory) 20C, a storage 20D, and an input / output interface (input / output I / F) 20E. Each component is connected to each other so as to be able to communicate with each other via a bus 20F.

[0052] The CPU 20A is a central processing unit that executes various programs and controls each part. That is, the CPU 20A reads the programs from the ROM 20B or the storage 20D, and executes the programs using the RAM 20C as a working area. The CPU 20A controls each of the above components and performs various arithmetic processing according to the programs recorded in the ROM 20B or the storage 20D.

[0053] The ROM 20B stores various programs and various data. The RAM 20C temporarily stores programs or data as a working area.

[0054] The storage 20D is configured with a hard disk drive (HDD) or a solid state drive (SSD), and stores various programs including an operating system, and various data.

[0055] The input / output interface 20E is an interface for communicating with each of the other devices (the DCU 24 in this embodiment). Therefore, the check sonar ECU 20 is configured to be able to transmit and receive data to and from the smartphone 14 (on which the remote parking app is started) via the DCU 24.

[0056] Next, an example of the functional configuration of the checksonator ECU 20 will be described with reference to FIG.

[0057] The Clissona ECU 20 has a start information acquisition unit 30, a smartphone ID information transmission / reception unit 32, a matching result reception unit 34, an operation reception unit 35, a key operation request unit 36, a key operation detection unit 37, and an acceptance / rejection information transmission unit 38. Each functional configuration is realized by the CPU 20A reading and executing a program stored in the ROM 20B or the storage 20D.

[0058] The start information acquisition unit 30 detects that a remote parking operation has started by acquiring an operation start signal transmitted from the smartphone 14 to the vehicle 12 side when the remote parking app is launched on the smartphone 14.

[0059] The smartphone ID information transmitting / receiving unit 32 acquires the smartphone ID information transmitted from the smartphone 14 to the vehicle 12 side together with the operation start signal, and transmits the smartphone ID information to the verification ECU 22 .

[0060] The verification result receiving unit 34 receives the verification result transmitted from the verification ECU 22 based on whether or not an electronic key having an electronic key ID that is registered in pairing with the smartphone ID has been detected.

[0061] When the operation receiving unit 35 receives a matching OK signal described later from the matching ECU 22, or when the key operation detection unit 37 detects operation of an electronic key under specified conditions, the Clissona ECU 20 enables the Clissona ECU 20 to accept a remote parking operation (signal) from the smartphone 14.

[0062] This operation reception unit 35 corresponds to the "control unit."

[0063] If the comparison result is negative, the key operation request unit 36 ​​transmits a key operation request signal to the smartphone 14, requesting the operation of the electronic key 16. This key operation request unit 36 ​​corresponds to a "first transmission unit."

[0064] The key operation detection unit 37 detects whether the electronic key operation requested by the key operation request signal has been performed. As an example, the key operation detection unit 37 detects (confirms) the operation of the electronic key 16 by detecting the operation of a part of the vehicle 12 (e.g., wireless unlocking of the door) caused by the key operation in the vehicle 12 within a predetermined time from the transmission of the key operation request signal.

[0065] If the matching result is positive, or if the matching result is negative but operation of the electronic key 16β different from the electronic key 16α registered in pairing with the smartphone 14 is detected (confirmed), the acceptance information transmission unit 38 transmits an acceptance signal to the smartphone 14 indicating that the remote parking operation is acceptable. On the other hand, if the matching result is negative and operation of the electronic key 16β is not confirmed, the acceptance information transmission unit 38 transmits an acceptance failure signal to the smartphone 14 indicating that the remote parking operation is not acceptable.

[0066] Next, the hardware configuration of the verification ECU 22 will be described with reference to Fig. 2. Components similar to those in the hardware configuration of the checksonator ECU 20 are given the same reference numerals after the reference numeral 22, and detailed description thereof will be omitted.

[0067] That is, the verification ECU 22 includes a CPU 22A, a ROM 22B, a RAM 22C, a storage 22D, and an input / output interface (input / output I / F) 22E. Each component is connected to each other so as to be able to communicate with each other via a bus 22F.

[0068] The storage 22D of the verification ECU 22 stores a registration table 46 (see the dashed line in FIG. 2) in which the correspondence between the smartphone 14 and the corresponding electronic key 16 is registered.

[0069] The matching ECU 22 is connected to a wireless device 40 (see dashed line in Figure 2), an outdoor antenna 42 (see dashed line in Figure 2), an indoor antenna 44 (see dashed line in Figure 2), and a display unit (touch panel) 48 (see dashed line in Figure 2) via the input / output I / F 22E.

[0070] Next, the functional configuration of the verification ECU 22 will be described.

[0071] 4, the verification ECU 22 has, as examples of functional configurations, a registration unit 50, an electronic key information acquisition unit 52, a smartphone information acquisition unit 54, a correspondence information acquisition unit 56, a determination unit 58, and a verification result transmission unit 60. Each functional configuration is realized by the CPU 22A reading and executing a program stored in the ROM 22B or the storage 22D.

[0072] The registration unit 50 checks whether the user wishes to associate and register (pair link registration) the smartphone 14 and electronic key 16 that the user normally uses (carries) at any timing when the user's entry is detected by the vehicle 12, and when performing pairing registration, the smartphone ID information of the smartphone 14 and the electronic key ID information of the electronic key 16 are associated with each other and recorded (registered) in a registration table 46 stored in the storage 22D. As a result, the smartphone 14, the electronic key 16, and the vehicle 12 are registered in association with each other.

[0073] When the display control unit 51 confirms with the user a desire to register pairing, it causes the display unit (touch panel) 48 provided in the vehicle 12 to display a message saying "Do you want to register the correspondence (pairing) between the electronic key and smartphone?", and when the user touches the "YES" button (agrees), it causes the display control unit 51 to display a message saying "Please set the pairing with your smartphone and Bluetooth (registered trademark)."

[0074] The electronic key information acquisition unit 52 detects that the electronic key 16 is outside the vehicle 12 and within a predetermined range from the vehicle 12 by using the exterior antenna 42 of the vehicle 12 to detect an output signal transmitted from the electronic key 16 that has detected a weak radio wave output from the wireless device 40. It also detects that the electronic key 16 is within the vehicle cabin by using the interior antenna 44 of the vehicle 12 to detect an output signal transmitted from the electronic key 16. At this time, ID information of the detected electronic key 16 (hereinafter referred to as "electronic key ID") is also acquired.

[0075] The smartphone information acquisition unit 54 acquires individual identification information (hereinafter referred to as "smartphone ID information") of the smartphone 14 by pairing with the verification ECU 22 via Bluetooth (registered trademark) during the above registration. In addition, the smartphone information acquisition unit 54 acquires the smartphone ID information from the smartphone 14 via the Clissona ECU 20 by starting a remote parking application on the smartphone 14. This smartphone information acquisition unit 54 corresponds to the "first acquisition unit."

[0076] The correspondence information acquisition unit 56 acquires information (electronic key ID) of the electronic key 16 associated with the smartphone 14 (smartphone ID) based on the correspondence relationship registered in the registration unit 50 (pairing registration).

[0077] The determination unit 58 determines whether the electronic key 16 having the electronic key ID acquired by the correspondence information acquisition unit 56 is located outside the vehicle 12 within a predetermined range from the vehicle 12. Specifically, the electronic key information acquisition unit 52 makes this determination based on whether the electronic key ID of the electronic key that is located outside the vehicle 12 within the predetermined range from the vehicle 12 matches a registered electronic key ID.

[0078] The matching result transmission unit 60 transmits a matching result signal indicative of the matching (determination) result of the determination unit 58 to the Checksonar ECU 20. Specifically, if the determination unit 58 detects an electronic key 16 with a predetermined ID number outside the vehicle 12 within a predetermined range from the vehicle 12, it outputs a matching OK signal to the Checksonar ECU 20. If the determination unit 58 does not detect an electronic key 16 with the predetermined ID number, it outputs a matching NG signal to the Checksonar ECU 20.

[0079] Next, the hardware configuration of the smartphone 14 will be described with reference to Fig. 2. Components similar to those in the hardware configuration of the smart phone ECU 20 will be given the same reference numerals after the reference numeral of 14, and detailed description thereof will be omitted.

[0080] That is, the smartphone 14 includes a CPU 14α, a ROM 14β, a RAM 14C, a storage 14D, and an input / output interface (input / output I / F) 14E. Each component is connected to each other via a bus 14F so as to be able to communicate with each other.

[0081] The storage 14D stores a remote parking application (program) 70 (see the dashed line in FIG. 2), and by starting the remote parking application 70, a matching process, which will be described later, is performed.

[0082] The smartphone 14 also has a touch panel 72 (see the dashed line in FIG. 2). The touch panel 72 functions as an operation (reception) screen when the remote parking app is started, and also functions as a display screen.

[0083] Next, an example of the functional configuration of the smartphone 14 will be described with reference to FIG.

[0084] The smartphone 14 has, in its functional configuration, an operation input receiving unit 80, a matching request unit 81, a key operation request acquiring unit 82, an acceptance / non-acceptance information acquiring unit 84, and a display control unit 86. Each functional configuration is realized by the CPU 14α reading out and executing a program (remote parking application 70) stored in the ROM 14β or the storage 14D.

[0085] The operation input receiving unit 80 receives operation input from the user through the touch panel 72 that functions as an operation (input) screen. For example, when the user touches the operation screen for remote parking, the operation input for remote parking is received and an operation signal is transmitted to the vehicle 12. This operation input receiving unit 80 corresponds to the "receiving unit."

[0086] When the remote parking application is started on the smartphone 14, the verification request unit 81 transmits an operation start signal to the vehicle 12 (the Smartphone ECU 20) and also transmits smartphone ID information of the smartphone 14.

[0087] This matching request unit 81 corresponds to the "second transmitting unit."

[0088] The key operation request acquisition unit 82 receives a key operation request signal transmitted from the check sonar ECU 20, thereby acquiring a key operation request from the vehicle 12 side.

[0089] The acceptance information acquisition unit 84 acquires acceptance information regarding the remote parking (parking assistance) operation from the clearsona ECU 20. Specifically, the acceptance information regarding the remote parking operation is acquired by receiving an acceptance signal or an acceptance not possible signal from the clearsona ECU 20.

[0090] This acceptance / rejection information acquiring unit 84 corresponds to the "second acquiring unit."

[0091] When the display control unit 86 receives the key operation request signal, it causes the touch panel 72 to display an operation request screen requesting the user to operate the electronic key 16 (for example, "Please perform wireless unlock operation").

[0092] Moreover, when an acceptance possible signal is received, a remote parking operation screen is displayed on the touch panel 72. Furthermore, when an acceptance impossible signal is received, a remote parking impossible screen is displayed on the touch panel 72 to inform the user that remote parking is not available.

[0093] (Processing flow) The process flow in the remote parking system 10 configured as above will be described with reference to the flowcharts in Figures 6 to 9. Here, the registration process for pairing the smartphone 14 that the user normally uses with the electronic key 16 in the remote parking system 10 will be described, and then the verification process when the user performs remote parking will be described.

[0094] (Registration process) The registration process in the verification ECU 22 will be described.

[0095] First, the registration process shown in FIG. 6 is started at any timing when it is detected that the user has entered the vehicle 12.

[0096] In step S100 of FIG. 6 (hereinafter, "FIG. 6" will be omitted), the CPU 22A of the verification ECU 22 uses the function of the electronic key information acquisition unit 52 to determine whether or not the electronic key is present inside the vehicle cabin based on whether or not the indoor antenna 44 receives an output signal from the electronic key that has received a weak radio wave transmitted from the wireless device 40.

[0097] If an affirmative determination is made in step S100, the process proceeds to step S101. On the other hand, if a negative determination is made in step S100, there is no electronic key to be registered for pairing, and therefore the registration process is terminated.

[0098] In step S101 , the CPU 22A of the verification ECU 22 obtains electronic key ID information of the detected electronic key 16 using the function of the electronic key information obtaining unit 52 .

[0099] Next, in step S102, the CPU 22A of the verification ECU 22, using the function of the correspondence information acquisition unit 56, refers to the registration information recorded in the registration table 46 stored in the storage 22D to determine whether the detected electronic key ID has already been registered for pairing.

[0100] If the determination in step S102 is affirmative, that is, if the detected electronic key 16 has already been paired, pairing registration is not necessary and the process ends.

[0101] On the other hand, if a negative determination is made in step S102, the process proceeds to step S104.

[0102] In step S104, the CPU 22A of the verification ECU 22 uses the function of the display control unit 51 to display a question regarding pairing registration on the display unit (touch panel) 48 provided in the vehicle 12, for example, the monitor of a car navigation device, such as "Do you want to pair and register the electronic key and smartphone with this vehicle?"

[0103] Next, in step S106, the CPU 22A of the verification ECU 22 determines, by the function of the registration unit 50, whether or not an agreement signal has been input by the user A operating the display unit (touch panel) .

[0104] If the determination in step S106 is negative, the registration process is immediately terminated, whereas if the determination in step S106 is positive, the process proceeds to step S108.

[0105] In step S108, the CPU 22A of the verification ECU 22 causes the display unit (touch panel) 48 to display a pairing request screen for setting up pairing with the vehicle 12 side via Bluetooth (registered trademark), using the function of the display control unit 51. For example, a message "Please pair the smartphone to be registered with the vehicle side via Bluetooth (registered trademark)" is displayed.

[0106] In step S110, the CPU 22A of the verification ECU 22 determines whether or not ID (hereinafter, referred to as "smartphone ID") information of the smartphone 14 has been acquired by the function of the smartphone information acquisition unit 54. That is, it determines whether or not information on the smartphone ID of the smartphone 14 has been acquired as a result of the user A setting up pairing between the smartphone 14 and the vehicle 12 side via Bluetooth (registered trademark).

[0107] If the determination in step S110 is affirmative, the process proceeds to step S112. On the other hand, if the determination in step S110 is negative after waiting until a predetermined time has elapsed since step S108, the registration process ends.

[0108] Next, in step S112, the CPU 22A of the matching ECU 22, using the function of the registration unit 50, registers (pairs) the “electronic key ID” of the electronic key 16 detected inside the vehicle cabin and the “smartphone ID” of the smartphone 14 in the registration table 46 stored in the storage 22D in association with each other (pairing registration).

[0109] In this way, one smartphone 14 is registered in association with one electronic key 16. Therefore, when there are multiple users using the vehicle 12, the electronic key 16α and smartphone 14α used by user A can be paired and registered, and the electronic key 16β and smartphone 14β used by user B can also be paired and registered. Even in this case, only one smartphone can be paired and registered with one electronic key.

[0110] [Matching process] Next, the verification process will be described. First, the process on the smartphone side will be described, then the process on the checksonner ECU side will be described, and finally the process on the verification ECU side will be described.

[0111] (Processing on the smartphone side) In order to perform remote parking, when user A launches the remote parking application 70 on the smartphone 14, the smartphone 14 starts a matching process.

[0112] In steps S200 and S201 in FIG. 7 (hereinafter, “in FIG. 7” will be omitted), the CPU 14α of the smartphone 14 transmits an operation start signal and information on the smartphone ID of the smartphone 14 to the vehicle 12 using the function of the matching request unit 81.

[0113] As will be described in detail later, on the vehicle 12 side, the verification ECU 22 determines whether or not the electronic key 16 having the electronic key ID associated (registered by pairing) with this smartphone ID (smartphone 14) has been detected outside the passenger compartment of the vehicle 12 within a predetermined range from the vehicle 12, and outputs a positive signal if it has been detected, or a negative signal if it has not been detected, to the checksona ECU 20. If the checksona ECU 20 receives a negative signal, a key operation request signal requesting operation of the electronic key is transmitted from the vehicle 12 to the smartphone 14.

[0114] Next, in step S202, the CPU 14α of the smartphone 14 determines, through the functions of the key operation request acquisition unit 82 and the acceptance information acquisition unit 84, whether or not a signal (a key operation request signal, an acceptance signal, or an acceptance not possible signal) has been received from the vehicle side.

[0115] If a negative determination is made in step S202, the process waits in step S202 until a signal is received. On the other hand, if a positive determination is made in step S202, the process proceeds to step S204.

[0116] In step S204, the CPU 14α of the smartphone 14 determines, by the function of the key operation request acquisition unit 82, whether or not the received signal is a key operation request signal.

[0117] If the determination in step S204 is affirmative, the process proceeds to step S206, and if the determination is negative, the process proceeds to step S208.

[0118] In step S206, the CPU 14α of the smartphone 14 uses the function of the display control unit 86 to display a key operation request screen for requesting the user to perform a key operation on the touch panel 72. For example, it displays "Please perform wireless unlock operation."

[0119] When a user who sees this display operates, for example, a wireless unlock operation, an electronic key 16β other than the electronic key 16α registered in pairing with the smartphone 14, the operation of the electronic key 16β is detected (confirmed) on the vehicle side, for example, by detecting a wireless unlock operation signal or a wireless unlock operation. If the operation of the electronic key 16β is detected, an acceptance signal is transmitted from the vehicle side to the smartphone 14, and if not, an acceptance not signal is transmitted.

[0120] After performing the screen display control in step S206, the CPU 14α of the smartphone 14 returns to step S202 and waits for the next signal reception.

[0121] On the other hand, in step S208, the CPU 14α of the smartphone 14 determines whether the received signal is an acceptable signal or not (an unacceptable signal) by the function of the acceptance information acquisition unit 84. If the result in step S208 is affirmative, the process proceeds to step S210, and if the result is negative, the process proceeds to step S212.

[0122] In step S210, the CPU 14α of the smartphone 14 displays an operation screen on the touch panel 72 to enable the user to perform a remote parking operation using the function of the display control unit 86. For example, an operation screen is displayed that allows the user to instruct the moving direction and parking position of the vehicle to perform remote parking.

[0123] When the user operates the operation screen of the touch panel 72, an operation signal for remote parking is transmitted to the vehicle 12, which causes the parking sensor ECU 20 to output a drive signal to each actuator, thereby performing remote parking of the vehicle 12.

[0124] Meanwhile, in step S212, the CPU 14α of the smartphone 14 uses the function of the display control unit 86 to display an operation-prohibited screen on the touch panel 72. For example, the touch panel 72 displays "Remote parking is not possible" or "Authentication not possible. Remote parking operation is not possible."

[0125] The CPU 14α of the smartphone 14 ends the authentication process by displaying the above-mentioned operation screen or the operation-prohibited screen on the touch panel 72.

[0126] (Chrisona ECU processing) 8, step S300 (hereinafter, "FIG. 8" will be omitted), the CPU 20A of the Clissona ECU 20 determines whether or not an operation start signal has been received from the smartphone 14, using the function of the start information acquisition unit 30. If a negative determination is made in step S300, the process waits in step S300, and if a positive determination is made, the process proceeds to step S302.

[0127] In step S302, the CPU 20A of the check-sona ECU 20 acquires the smartphone ID information transmitted from the smartphone 14 by using the function of the smartphone ID information transmitting / receiving unit 32, and outputs the smartphone ID information to the verification ECU 22.

[0128] In step S304, the CPU 20A of the checksonator ECU 20 determines whether or not a matching result signal (matching OK signal or matching NG signal) has been received from the matching ECU 22 through the function of the matching result receiving unit 34. If a negative determination is made in step S304, the process waits in step S304 until the matching result signal is received. On the other hand, if a positive determination is made in step S304, the process proceeds to step S306.

[0129] In step S306, the CPU 20A of the checksonator ECU 20 determines whether the received matching result signal is a matching OK signal or not (matching NG signal) by the function of the matching result receiving unit 34. If the determination in step S306 is affirmative, the process proceeds to step S314, and if the determination is negative, the process proceeds to step S308.

[0130] In step 308, the CPU 20A of the smart phone ECU 20 uses the function of the key operation request unit 36 ​​to send a key operation request signal to the smartphone 14 via the DCU 24. This key operation request signal is a signal that requests the touch panel 72 of the smartphone 14 to display an operation request screen that requests the user to operate the electronic key.

[0131] Next, in step S310, the CPU 20A of the Cleansona ECU 20 determines, through the function of the key operation detection unit 37, whether or not an operation using an electronic key 16β of the vehicle 12 other than the electronic key 16α has been confirmed within a predetermined time from the timing of the transmission of the key operation request signal. The key operation, for example, a wireless unlock operation, is confirmed by detecting a wireless unlock operation signal or a wireless unlock operation of the doors.

[0132] If the determination in step S310 is negative, the process proceeds to step S312, and if the determination is positive, the process proceeds to step S314.

[0133] In step S312, the CPU 20A of the check-sona ECU 20 uses the function of the acceptance / rejection information transmitting unit 38 to transmit an acceptance rejection signal to the smartphone 14 via the DCU 24, notifying the smartphone 14 that the remote parking operation from the smartphone 14 cannot be accepted. That is, the CPU 20A of the check-sona ECU 20 transmits the acceptance rejection signal to the smartphone 14 when it receives a matching NG signal from the matching ECU 22 (NO in step S306) and cannot confirm the operation of the electronic key 16β (NO in step S310).

[0134] In step S314, the CPU 20A of the checksona ECU 20 uses the function of the acceptance information transmission unit 38 to transmit an acceptance signal to the smartphone 14 via the DCU 24, notifying the smartphone 14 that the remote parking operation can be accepted (acceptance has started) from the smartphone 14. That is, the CPU 20A of the checksona ECU 20 transmits the acceptance signal to the smartphone 14 when it receives a verification OK signal from the verification ECU 22 (YES in step S306) or when it confirms the operation of the electronic key 16β (YES in step S310).

[0135] The checksonator ECU 20 ends the verification process by transmitting a non-acceptance signal (step S312) or an acceptance signal (step S314) to the smartphone 14.

[0136] (Processing on the verification ECU side) In step S400 in FIG. 9 (hereinafter, "FIG. 9" will be omitted), the CPU 22A of the verification ECU 22 determines whether or not the smartphone ID information has been acquired (received) from the checksonator ECU 20 using the function of the electronic key information acquisition unit 52.

[0137] If the determination in step S400 is negative, the process waits in step S400 until the smartphone ID information is acquired. On the other hand, if the determination in step S400 is positive, the process proceeds to step S402.

[0138] In step S402, the CPU 22A of the verification ECU 22, using the function of the correspondence information acquisition unit 56, refers to the registration table 46 stored in the storage 22D to determine whether there is an electronic key ID (electronic key 16) that is associated (registered by pairing) with the smartphone ID (smartphone 14).

[0139] If the determination in step S402 is negative, the process proceeds to step S410, and if the determination is positive, the process proceeds to step S404.

[0140] In step S404, the CPU 22A of the verification ECU 22 uses the function of the electronic key information acquisition unit 52 to search for an electronic key located outside the vehicle 12 within a predetermined range from the vehicle 12, and if an electronic key is detected (the output signal of the electronic key 16 is detected by the exterior antenna 42), acquires the electronic key ID information of the electronic key.

[0141] Next, in step S406, the CPU 22A of the verification ECU 22 determines, by the function of the determination unit 58, whether or not the electronic key 16 associated with the smartphone 14 has been detected. Specifically, if an electronic key is detected outside the vehicle 12 within a predetermined range from the vehicle 12, it is determined whether or not the electronic key ID of the electronic key matches the electronic key ID associated with the smartphone ID of the smartphone 14.

[0142] If the determination in step S406 is affirmative, the process proceeds to step S408, and if the determination is negative, the process proceeds to step S410.

[0143] In step S408, the CPU 22A of the verification ECU 22 transmits a verification OK signal to the checksonator ECU 20 by using the function of the verification result transmission unit 60.

[0144] This is done by detecting the electronic key 16 that has been registered in association with the smartphone 14 outside the vehicle 12 within a specified range of the vehicle 12, and determining that the user operating the smartphone 14 is in possession of the electronic key 16 that is associated with the smartphone 14, and determining that user authentication (matching) is OK.

[0145] On the other hand, in step S410, the CPU 22A of the verification ECU 22 uses the function of the verification result transmission unit 60 to transmit a verification NG signal to the check-sona ECU 20 (from the check-sona ECU 20 to the smartphone 14 via the DCU 24).

[0146] This is because when an electronic key is not registered in association with the smartphone 14 (NO in step S402) or when the electronic key 16 that was registered in association with the smartphone 14 cannot be detected outside the vehicle 12 within a specified range of the vehicle 12, it is determined that the user operating the smartphone 14 cannot be authenticated and the match is determined to be NG.

[0147] In this manner, the verification ECU 22 transmits a verification result signal (verification OK signal or verification NG signal) to the checksonator ECU 20, thereby completing the verification process.

[0148] (effect) In this way, in the remote parking system 10 of this embodiment, the smartphone 14 normally carried by the user of the vehicle 12 and the electronic key 16 (with the vehicle 12) are associated and pre-registered (paired) in the verification ECU 22 of the vehicle 12 (recorded in the registration table 46).

[0149] In this way, by previously registering the combination of the smartphone 14 and electronic key 16 normally owned by the (authorized) user of the vehicle 12 on the vehicle 12 side as a pair, the user can operate the remote parking function without operating the electronic key 16 by simply launching the remote parking app on the smartphone 14 outside the vehicle 12 within a specified range of the vehicle 12.

[0150] In addition, since it is confirmed that the electronic key 16 detected outside the vehicle 12 within a predetermined range from the vehicle 12 is the electronic key 16 that has been paired and registered in advance with the smartphone 14, it can be reliably determined that the electronic key 16 is owned by the user operating the smartphone 14. In other words, user authentication can be performed reliably.

[0151] Furthermore, even if the user has not registered the correspondence between the smartphone 14 and the electronic key 16 in advance in the vehicle 12, or if the user has an electronic key 16β other than the registered electronic key 16α, the vehicle 12 can display an operation request screen on the touch panel 72 of the smartphone 14 to prompt the user to operate the electronic key 16β, making it possible to perform remote parking operation (acceptance) on the condition that the vehicle detects (confirms) the operation of the electronic key 16β.

[0152] In this case, if the operation of the electronic key 16β is a wireless unlock operation, it is preferable because the user does not need to approach excessively close to the vehicle 12 to perform the operation. This is because there is a risk that the user may be positioned excessively close to the vehicle 12 when performing a remote parking operation.

[0153] In addition, the correspondence between the smartphone 14 and the electronic key 16 can be registered in a one-to-one manner for multiple smartphones 14 (e.g., smartphones 14α, 14β) with different electronic keys 16 (e.g., electronic keys 16α, 16β). That is, combinations such as "smartphone 14α-electronic key 16α" and "smartphone 14β-electronic key 16β" can be registered. As a result, when multiple users A and B have different electronic keys 16α and 16β for the vehicle 12, each occupant A and B can perform remote parking by simply starting the remote parking app on their respective smartphones 14α and 14β, without operating the electronic keys 16α and 16β.

[0154] Furthermore, if the electronic key 16α registered and paired with the smartphone 14 cannot be detected, and the operation of an electronic key 16β different from the electronic key 16α cannot be detected (confirmed), a screen indicating that remote parking is not accepted can be displayed on the smartphone 14 to notify the user that remote parking operation is not possible.

[0155] (others) In this embodiment, all information exchange between the smartphone 14 and the verification ECU 22 is performed via the checksonar ECU 20, but the present invention is not limited to this. A part or all of the information may be exchanged by the smartphone 14 and the verification ECU 22, or only information required by the checksonar ECU 20 may be transmitted from the smartphone 14 and the verification ECU 22 to the checksonar ECU 20. In addition, in this embodiment, an operation start signal and smartphone ID information were sent to the vehicle side by launching the remote parking app on smartphone 14, but the configuration may also be such that the operation start signal and smartphone ID information are sent to the vehicle side by performing an operation start operation on the operation screen of smartphone 14.

[0156] Although the emergency call device and the like according to the embodiment have been described above, it goes without saying that the present invention can be embodied in various forms without departing from the spirit and scope of the present invention.

[0157] Moreover, the display process that the CPU reads the software (program) and executes in the above embodiment may be executed by various processors other than the CPU. In this case, examples of the processor include a PLD (Programmable Logic Device) such as an FPGA (Field-Programmable Gate Array) whose circuit configuration can be changed after manufacture, and a dedicated electric circuit such as an ASIC (Application Specific Integrated Circuit) which is a processor having a circuit configuration designed exclusively for executing a specific process. Moreover, the process may be executed by one of these various processors, or may be executed by a combination of two or more processors of the same or different types (for example, a plurality of FPGAs, and a combination of a CPU and an FPGA). Moreover, the hardware structure of these various processors is, more specifically, an electric circuit that combines circuit elements such as semiconductor elements.

[0158] Furthermore, in the above embodiment, various data are stored in the storage, but this is not limiting. For example, a recording medium such as a CD (Compact Disk), a DVD (Digital Versatile Disk), or a USB (Universal Serial Bus) memory may be used as the storage unit. In this case, various programs and data are stored in these recording media. [Explanation of symbols]
