[0004] In the digital key system of Patent Document 1, after communication between the mobile terminal and the vehicle is established by BLE wireless communication, the distance to the mobile terminal is measured using UWB wireless communication, and after detecting that the mobile terminal is located in the vicinity of the vehicle, the distance measurement of the mobile terminal by UWB wireless communication is started.

[0005] Incidentally, the ranging by BLE wireless communication may be less accurate than the ranging by UWB wireless communication. Also, the accuracy of the ranging by BLE wireless communication varies depending on the performance of the mobile terminal and the environment around the vehicle. Therefore, it may be difficult to uniformly maintain the accuracy of the ranging by BLE wireless communication in consideration of the performance of the mobile terminal, the environment around the vehicle, etc. That is, when performing ranging by UWB wireless communication according to the result of ranging by BLE wireless communication, there is a risk of erroneously detecting the mobile terminal and performing unnecessary ranging by UWB wireless communication.

[0006] An object of the present invention is to provide an information processing apparatus, a vehicle, an information processing method, and an information processing program that can suppress the execution of unnecessary ranging by UWB wireless communication when performing ranging by UWB wireless communication according to the result of ranging by BLE wireless communication.

[0007] The information processing apparatus according to claim 1 communicates with a mobile terminal using BLE wireless communication, and when the intensity of the signal related to the BLE wireless communication is equal to or higher than a predetermined threshold value, starts ranging between the own apparatus and the mobile terminal using UWB wireless communication, a determination unit that determines whether the ranging result by the UWB wireless communication satisfies a predetermined operation condition, and a notification unit that notifies the mobile terminal of a proposal to change the threshold value when the operation condition is satisfied.

[0008] The information processing apparatus according to claim 1 starts ranging the distance to the mobile terminal by UWB wireless communication when the intensity of the signal in the BLE wireless communication is equal to or higher than a predetermined threshold value, and notifies the mobile terminal that the threshold value is to be changed when the ranging result by the UWB wireless communication satisfies a predetermined operation condition. That is, according to the information processing apparatus, when performing ranging by UWB wireless communication according to the result of ranging by BLE wireless communication, the execution of unnecessary ranging by UWB wireless communication can be suppressed.

[0009] The information processing apparatus according to claim 2 is the information processing apparatus according to claim 1, wherein the determination unit determines at least one of the conditions of whether the duration of the distance measurement by the UWB wireless communication is equal to or longer than a predetermined time and whether the frequency of the distance measurement by the UWB wireless communication is equal to or higher than a predetermined frequency as the operation condition.

[0011] The information processing apparatus according to claim 3 is the information processing apparatus according to claim 2, wherein after starting the distance measurement by the UWB wireless communication, the distance measurement unit stops the distance measurement by the UWB wireless communication when the intensity of the signal is less than a predetermined threshold value.

[0015] The vehicle according to claim 5 includes the information processing apparatus according to any one of claims 1 to 4, and the information processing apparatus determines whether the operation condition is satisfied when an operation of the own vehicle by the user cannot be detected.

[0016] According to the vehicle according to claim 5, it is possible to detect that the user is in a position where the own vehicle cannot be operated, and propose a change in the threshold value to the user.

[0017] The vehicle according to claim 6 is the vehicle according to claim 5, wherein the information processing device counts the number of times of starting distance measurement by the UWB wireless communication, and when the operation is detected, initializes the number of times.

[0018] According to the vehicle of claim 6, it is possible to suppress the notification of unnecessary proposals.

[0019] The information processing method according to claim 7 performs communication between the own device and the mobile terminal using BLE wireless communication.

Modes for Carrying Out the Invention

[0025] A control system including a control ECU (Electronic Control Unit) as an information processing device of the present invention will be described. The control ECU functions as a device that controls the search for a mobile terminal that transmits an instruction related to a vehicle using BLE (Bluetooth Low Energy) wireless communication and UWB (Ultra Wide Band) wireless communication.

[0026] (Control System) As shown in FIG. 1, the control system 10 of the present embodiment includes a vehicle 12 and a mobile terminal 30. The vehicle 12 includes a control ECU 20 as an information processing device and a plurality of ECUs 22 that are devices for controlling the devices mounted on the vehicle 12. The control ECU 20 and the mobile terminal 30 can be mutually connected by BLE wireless communication and UWB wireless communication.

[0027] The control ECU 20 has a function of acquiring communication information based on the CAN (Controller Area Network) protocol transmitted from each ECU 22. As the ECU 22 of the present embodiment, a body ECU described later is exemplified. The control ECU 20 and each ECU 22 are mutually connected via an external bus 20H.

[0028] In addition, the control ECU 20 communicates with the mobile terminal 30 using BLE wireless communication and UWB wireless communication. The control ECU 20 measures the distance to the mobile terminal 30 using the signal strength in BLE wireless communication, and when the signal strength is equal to or greater than a predetermined threshold (the mobile terminal 30 exists within a predetermined distance range), UWB wireless communication is performed. The control ECU 20 measures the distance to the mobile terminal 30 using the propagation time of the signal by UWB wireless communication (TOA: Time Of Arrival). Here, when the ranging result by UWB wireless communication satisfies a predetermined operating condition, the control ECU 20 transmits a notification regarding a proposal to change the threshold of the signal strength related to BLE wireless communication to the mobile terminal 30. In the following, the threshold of the signal strength related to BLE wireless communication is referred to as the "intensity threshold".

[0029] The mobile terminal 30 is a terminal such as a smartphone that can be carried by the owner of the vehicle 12. A digital key related to the vehicle 12 is pre-stored in the mobile terminal 30, and the mobile terminal 30 can perform operations such as locking and unlocking the doors in the vehicle 12 by remote control using the digital key. When the mobile terminal 30 receives a notification related to the change of the intensity threshold from the vehicle 12, it displays the notification on the monitor. The mobile terminal 30 transmits the changed value of the intensity threshold (hereinafter referred to as the "changed value") input by the user to the control ECU 20. In this embodiment, the form in which the terminal communicating with the vehicle 12 is the mobile terminal 30 carried by the user will be described. However, it is not limited to this. For example, if the user can carry it, terminals such as a tablet and a car navigation device may be used.

[0030] As an example, as shown in FIG. 2, when the mobile terminal 30 is included in the range 40 where BLE wireless communication is possible, distance measurement is performed by BLE wireless communication. Also, as an example, as shown in FIG. 3, when the mobile terminal 30 held by the user enters the range 41 indicating the intensity threshold as the user approaches the vehicle 12, distance measurement by UWB wireless communication is started.

[0031] Here, for example, when the vehicle 12 is parked in a parking lot adjacent to a building such as a house, the user may approach the vehicle 12 without the intention of getting into the vehicle 12, and the mobile terminal 30 held by the user may be included in the range 40 and the range 41.

[0032] Therefore, in response to the notification by the control ECU 20, the user transmits the changed value to the control ECU 20 to change the intensity threshold, so that, as shown in FIG. 4 as an example, the mobile terminal 30 is outside the range 41 indicating the intensity threshold. That is, distance measurement by UWB wireless communication is no longer performed.

[0033] FIG. 5 shown as an example is a sequence diagram showing an example of the process executed by the cooperation of the control ECU 20 and the mobile terminal 30.

[0034] As shown in FIG. 5, the control ECU 20 and the mobile terminal 30 perform BLE wireless communication (step S101).

[0035] The control ECU 20 determines whether the intensity of the signal in the BLE wireless communication is equal to or greater than the intensity threshold (step S102). If the intensity of the signal is equal to or greater than the intensity threshold (step S102: Yes), the control ECU 20 proceeds to step S103. On the other hand, if the intensity of the signal is not equal to or greater than the intensity threshold (the intensity of the signal in the BLE wireless communication is less than the intensity threshold) (step S102: No), the control ECU 20 waits until the intensity of the signal becomes equal to or greater than the intensity threshold.

[0036] The control ECU 20 and the mobile terminal 30 perform UWB wireless communication together with the BLE wireless communication (step S103).

[0037] The control ECU 20 determines whether a predetermined operating condition in the UWB wireless communication is satisfied (step S104). If the predetermined operating condition is satisfied (step S104: Yes), the control ECU 20 proceeds to step S105. On the other hand, if the predetermined operating condition is not satisfied (step S104: No), the control ECU 20 continues the BLE wireless communication and the UWB wireless communication.

[0038] The control ECU 20 notifies the mobile terminal 30 of a proposal to change the intensity threshold (step S105).

[0039] After receiving the notification, the mobile terminal 30 transmits the changed value input by the user to the control ECU 20 (step S106).

[0040] The control ECU 20 accepts the changed value from the mobile terminal 30 (step S107) and sets the accepted changed value as the intensity threshold (step S108).

[0041] (Vehicle) As shown in FIG. 6, the vehicle 12 according to the present embodiment includes a control ECU 20, a plurality of ECUs 22, and a plurality of in-vehicle devices 24.

[0042] The control ECU 20 includes a CPU (Central Processing Unit) 20A, a ROM (Read Only Memory) 20B, a RAM (Random Access Memory) 20C, an in-vehicle communication I / F (Interface) 20D, a BLE communication unit 20E, and a UWB communication unit 20F. The CPU 20A, the ROM 20B, the RAM 20C, the in-vehicle communication I / F 20D, the BLE communication unit 20E, and the UWB communication unit 20F are communicably connected to each other via an internal bus 20G.

[0043] The CPU 20A is a central processing unit that executes various programs and controls each part. That is, the CPU 20A reads a program from the ROM 20B and executes the program using the RAM 20C as a work area.

[0044] The ROM 20B stores various programs and various data. The ROM 20B of the present embodiment stores a control program 100 that executes a process of controlling the search for the mobile terminal 30. The RAM 20C temporarily stores a program or data as a work area.

[0045] The in-vehicle communication I / F 20D is an interface for connecting to each ECU 22. The communication standard based on the CAN protocol is used for the interface. The in-vehicle communication I / F 20D is connected to an external bus 20H.

[0046] The BLE communication unit 20E has a BLE antenna 24A connected thereto. The BLE communication unit 20E is a wireless communication module for communicating with devices such as the mobile terminal 30 via the BLE antenna 24A. The BLE antenna 24A is a communication device that performs wireless communication in the Bluetooth frequency band (2.4 GHz), for example, transmits a request signal to the mobile terminal 30, and receives a response signal from the mobile terminal 30.

[0047] The UWB communication unit 20F is connected to the UWB antenna 24B. The UWB communication unit 20F is a wireless communication module for communicating with devices such as the mobile terminal 30 via the UWB antenna 24B. The UWB antenna 24B is a communication device that performs wireless communication using, for example, a pulsed radio wave signal in an ultra-wideband (e.g., from 3.1 GHz to 10.6 GHz), transmits a request signal to the mobile terminal 30, and receives a response signal from the mobile terminal 30.

[0048] The ECU 22 includes at least the body ECU 22A. The body ECU 22A controls each part of the body of the vehicle 12. The locking actuator 24C that constitutes the in-vehicle device 24 is connected to the body ECU 22A. The body ECU 22A locks and unlocks the doors of the vehicle 12 in response to instructions for locking and unlocking the doors of the vehicle 12. The locking actuator 24C locks and unlocks the doors in response to the instructions. Here, when the user performs an operation to open the door of the vehicle 12, the body ECU 22A according to the present embodiment notifies the control ECU 20 that the door has been operated.

[0049] As shown in FIG. 7, in the control ECU 20 of the present embodiment, the CPU 20A functions as the BLE ranging unit 200, the UWB ranging unit 210, the storage unit 220, the determination unit 230, the notification unit 240, the reception unit 250, and the setting unit 260 by executing the control program 100.

[0050] The BLE ranging unit 200 measures the distance to the mobile terminal 30 using the strength of the signal in the BLE wireless communication. Specifically, the BLE ranging unit 200 measures the distance to the mobile terminal 30 according to the strength (RSSI: Received Signal Strength Indication) of the signal received from the mobile terminal 30 in the BLE wireless communication.

[0051] When the intensity of the signal received by the UWB ranging unit 210 through BLE wireless communication is equal to or greater than the intensity threshold, the UWB ranging unit 210 communicates with the mobile terminal 30 and starts ranging with the mobile terminal 30 through UWB wireless communication. Here, after starting the ranging by the UWB ranging unit 210 through UWB wireless communication, when the intensity of the signal in the BLE wireless communication becomes less than the intensity threshold, the UWB ranging unit 210 stops the ranging by the UWB wireless communication.

[0052] The storage unit 220 counts the number of times the ranging by the UWB ranging unit 210 is stopped (hereinafter referred to as the "stop count") and stores the stop count. In addition, the storage unit 220 measures the duration of the ranging by the UWB ranging unit 210 and stores the duration. In this embodiment, as the frequency of stopping the ranging by the UWB ranging unit 210, a form will be described in which the stop count of stopping the ranging until the vehicle 12 is operated or the intensity threshold is changed is counted. However, it is not limited to this. The total number of times the ranging is stopped may be counted, or the number of times the ranging is stopped within a predetermined period may be counted.

[0053] The determination unit 230 determines whether a predetermined operating condition in the UWB wireless communication is satisfied. Here, the operating condition is that when the stop count of stopping the ranging by the UWB ranging unit 210 is equal to or greater than a predetermined number of times, and when the duration of the ranging by the UWB ranging unit 210 is equal to or greater than a predetermined time.

[0054] In addition, the determination unit 230 determines whether a notification indicating that the door of the vehicle 12 has been operated has been transmitted from the body ECU 22A.

[0055] When the notification unit 240 satisfies predetermined operating conditions in UWB wireless communication, it notifies the mobile terminal 30 of a proposal to change the intensity threshold. Specifically, the notification unit 240 notifies the mobile terminal 30 when no notification is being transmitted from the body ECU 22A and the number of times the distance measurement by the UWB distance measurement unit 210 has been stopped is equal to or greater than a predetermined number of times, or when the duration of the distance measurement by the UWB distance measurement unit 210 is equal to or greater than a predetermined time. In this embodiment, the case where notification is made when the number of stops is equal to or greater than a predetermined number of times or the duration is equal to or greater than a predetermined time has been described. However, it is not limited to this. Notification may be made when the number of stops is equal to or greater than a predetermined number of times and the duration is equal to or greater than a predetermined time.

[0056] The reception unit 250 receives a change value from the mobile terminal 30. Specifically, after notifying the mobile terminal 30 of a proposal to change the intensity threshold, the reception unit 250 receives a change value for changing the intensity threshold.

[0057] The setting unit 260 sets the received change value as the intensity threshold. By setting the change value received from the mobile terminal 30 as the intensity threshold, the execution of distance measurement by UWB wireless communication is suppressed.

[0058] (Flow of processing) Next, with reference to FIG. 8, the operation of the control ECU 20 according to this embodiment will be described. FIG. 8 is a flowchart showing an example of the flow of control processing according to this embodiment. The control processing shown in FIG. 8 is executed when the CPU 20A reads and executes the control program 100 from the ROM 20B. The control processing shown in FIG. 8 is executed, for example, when the control ECU 20 detects the mobile terminal 30.

[0059] In step S201, the CPU 20A executes BLE wireless communication with the mobile terminal 30. Hereinafter, the CPU 20A continuously executes BLE wireless communication.

[0060] In step S202, the CPU 20A measures the distance to the mobile terminal 30 using the signal strength in BLE wireless communication.

[0061] In step S203, the CPU 20A determines whether the signal strength in BLE wireless communication is equal to or greater than the strength threshold. If the signal strength is equal to or greater than the strength threshold (step S203: YES), the CPU 20A proceeds to step S204. On the other hand, if the signal strength is less than the strength threshold (step S203: NO), the CPU 10A returns to step S202 and continues to measure the distance by BLE wireless communication.

[0062] In step S204, the CPU 20A performs UWB wireless communication with the mobile terminal 30.

[0063] In step S205, the CPU 20A measures the distance to the mobile terminal 30 using the signal propagation time in UWB wireless communication. Here, the CPU 20A measures the duration of distance measurement and stores the duration.

[0064] In step S206, the CPU 20A measures the distance to the mobile terminal 30 using the signal strength in BLE wireless communication.

[0065] In step S207, the CPU 20A determines whether the signal strength in BLE wireless communication is equal to or greater than the strength threshold. If the signal strength is equal to or greater than the strength threshold (step S207: YES), the CPU 20A proceeds to step S209. On the other hand, if the signal strength is less than the strength threshold (step S207: NO), the CPU 10A proceeds to step S208.

[0066] In step S208, the CPU 20A disconnects the UWB wireless communication with the mobile terminal 30 and stops the distance measurement by UWB wireless communication. Here, the CPU 20A sets 0 to the duration and increments the stop count by 1.

[0067] In step S209, the CPU 20A determines whether there has been an operation on the vehicle 12 by the user. If there has been an operation on the vehicle 12 by the user (step S209: YES), the CPU 20A proceeds to step S215. On the other hand, if there has been no operation on the vehicle 12 by the user (step S209: NO), the CPU 10A proceeds to step S210.

[0068] In step S210, the CPU 20A determines whether the duration of distance measurement by UWB wireless communication is equal to or greater than a predetermined time. If the duration is equal to or greater than the predetermined time (step S210: YES), the CPU 20A proceeds to step S212. On the other hand, if the duration is less than the predetermined time (step S210: NO), the CPU 10A proceeds to step S211.

[0069] In step S211, the CPU 20A determines whether the number of stops of distance measurement by UWB wireless communication is equal to or greater than a predetermined number of times. If the number of stops is equal to or greater than the predetermined number of times (step S211: YES), the CPU 20A proceeds to step S212. On the other hand, if the number of stops is less than the predetermined number of times (step S211: NO), the CPU 10A proceeds to step S205 to continue distance measurement by UWB wireless communication.

[0070] In step S212, the CPU 20A notifies the mobile terminal 30 of a proposal to change the intensity threshold.

[0071] In step S213, the CPU 20A receives a change value from the mobile terminal 30.

[0072] In step S214, the CPU 20A sets the received change value as the intensity threshold.

[0073] In step S215, the CPU 20A initializes the duration and the number of stops.

[0074] In step S216, the CPU 20A determines whether to end the process. If it is determined to end the process (step S216: YES), the CPU 20A ends the process. On the other hand, if it is determined not to end the process (step S216: NO), the CPU 20A proceeds to step S201 and executes BLE wireless communication with the mobile terminal 30.

[0075] (Summary of the Embodiment) When the signal strength in the BLE wireless communication is equal to or greater than a predetermined threshold, the control ECU 20 of the present embodiment starts distance measurement of the distance to the mobile terminal by UWB wireless communication, and when the distance measurement result by the UWB wireless communication satisfies a predetermined operating condition, the control ECU 20 notifies the mobile terminal of the change of the threshold.

[0076] As described above, according to the present embodiment, when performing distance measurement by UWB wireless communication according to the result of distance measurement by BLE wireless communication, it is possible to suppress the execution of unnecessary distance measurement by UWB wireless communication.

[0077] [Remarks] Note that various processes executed by the CPU 20A by loading software (program) in the above embodiment may be executed by various processors other than the CPU. Examples of the processor in this case include a PLD (Programmable Logic Device) whose circuit configuration can be changed after manufacture, such as an FPGA (Field-Programmable Gate Array), and a dedicated electric circuit which is a processor having a circuit configuration dedicated to executing specific processes, such as an ASIC (Application Specific Integrated Circuit).

[0078] Also, in the above embodiment, each program has been described in a mode where it is pre-stored (installed) in a non-transitory computer-readable recording medium.
