[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of an embodiment will be described in detail below with reference to the accompanying drawings. Fig. 1 illustrates a configuration of an authentication system 10 according to an embodiment. The authentication system 10 is an example of a remote control system.

[0011] The authentication system 10 includes a first mobile device 11. The first mobile device 11 is a device that can be carried by a person. In this example, the first mobile device 11 is carried by a first person 21.

[0012] The authentication system 10 includes a second mobile device 12. The second mobile device 12 is a device that can be carried by a person. In this example, the second mobile device 12 is carried by a second person 22.

[0013] The authentication system 10 may be used, for example, to authorize a first person 21 to use a vehicle 30 by authenticating a first mobile device 11, and to authorize a second person 22 to use the vehicle 30 by authenticating a second mobile device 12. The shape of the vehicle 30 is merely exemplary. The vehicle 30 is an example of a moving object.

[0014] The authentication system 10 includes a communication device 13. In this example, the communication device 13 is mounted on a vehicle 30. The communication device 13 includes an antenna capable of wireless communication with the first mobile device 11 and the second mobile device 12.

[0015] The authentication system 10 includes a control device 14. In this example, the control device 14 is mounted on a vehicle 30. The control device 14 is configured to control the operation of a locking / unlocking device 31 mounted on the vehicle 30 based on an authentication process. The locking / unlocking device 31 is a device that locks and unlocks the doors of the vehicle 30. The locking / unlocking device 31 is an example of a controlled device.

[0016] The first mobile device 11 is configured to transmit a first request signal RS1 by radio wave to request the locking / unlocking device 31 to lock or unlock the door. The first request signal RS1 includes first request information RQ1 and first authentication information AT1. The first request information RQ1 is information indicating whether the operation requested of the locking / unlocking device 31 is a locking operation or an unlocking operation. The first authentication information AT1 is information for identifying at least one of the first mobile device 11 and the first person 21. The first request signal RS1 may be an analog signal or a digital signal.

[0017] The second mobile device 12 is configured to transmit a second request signal RS2 by radio wave to request the locking / unlocking device 31 to lock or unlock the door. The second request signal RS2 includes second request information RQ2 and second authentication information AT2. The second request information RQ2 is information indicating whether the operation requested of the locking / unlocking device 31 is a locking operation or an unlocking operation. The second authentication information AT2 is information for identifying at least one of the second mobile device 12 and the second person 22. The second request signal RS2 may be an analog signal or a digital signal.

[0018] 2, the communication device 13 includes a reception unit 141. The reception unit 141 is configured as an interface that receives first request information RQ1 and first authentication information AT1 included in a first request signal RS1 received by the communication device 13. When the first request signal RS1 is an analog signal, the reception unit 141 includes an appropriate conversion circuit including an A / D converter.

[0019] Similarly, the reception unit 141 is configured as an interface that receives the second request information RQ2 and the second authentication information AT2 contained in the second request signal RS2 received by the communication device 13. When the second request signal RS2 is an analog signal, the reception unit 141 includes an appropriate conversion circuit including an A / D converter.

[0020] The control device 14 includes a processing unit 142. The processing unit 142 is configured to compare the first authentication information AT1 acquired by the reception unit 141 with the first authentication information AT1 stored in a storage device (not shown) when the first request signal RS1 is received by the communication device 13. When the degree of match between the two exceeds a threshold, the authentication of the first mobile device 11 is established.

[0021] Similarly, the processing unit 142 is configured to compare the second authentication information AT2 acquired by the reception unit 141 with the second authentication information AT2 stored in a storage device (not shown) when the second request signal RS2 is received by the communication device 13. When the degree of match between the two exceeds a threshold, the second mobile device 12 is authenticated.

[0022] The control device 14 includes an output unit 143. The processing unit 142 allows the output of a control signal CS from the output unit 143. The control signal CS is a signal that controls the operation of the locking / unlocking device 31. The control signal CS may be a digital signal or an analog signal. When the control signal CS is an analog signal, the output unit 143 includes an appropriate conversion circuit including a D / A converter.

[0023] The processing unit 142 is configured to output, when authentication of the first mobile device 11 is successful, from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform the operation (locking or unlocking) specified by the first request information RQ1.

[0024] Similarly, the processing unit 142 is configured to output, when authentication of the second mobile device 12 is successful, a control signal CS from the output unit 123 to cause the locking / unlocking device 31 to perform the operation (locking or unlocking) specified by the second request information RQ2.

[0025] 1, a first request signal RS1 wirelessly transmitted from the first mobile device 11 and a second request signal RS2 wirelessly transmitted from the second mobile device 12 may be simultaneously received by the communication device 13. In other words, the first request information RQ1 and the second request information RQ2 may be simultaneously received by the receiving unit 141 of the control device 14.

[0026] The expression "accepted simultaneously" used here means that the second request information RQ2 is accepted by the accepting unit 141 before authentication of the first mobile device 11 based on the first authentication information AT1 is established, or the first request information RQ1 is accepted by the accepting unit 141 before authentication of the second mobile device 12 based on the second authentication information AT2 is established. In other words, the time when the first request information RQ1 is accepted by the accepting unit 141 and the time when the second request information RQ2 is accepted by the accepting unit 141 may differ within a certain time range.

[0027] The process performed by the processing unit 142 of the control device 14 in such a case will be described with reference to FIG.

[0028] The processing unit 142 determines whether a plurality of requests have been received simultaneously by the receiving unit 141 (STEP 1). That is, the processing unit 142 determines whether the first request information RQ1 and the second request information RQ2 have been received simultaneously by the receiving unit 141.

[0029] If it is determined that the first request information RQ1 and the second request information RQ2 have been received simultaneously by the receiving unit 141 (YES in STEP 1), the processing unit 142 determines whether the operation of the locking / unlocking device 31 specified by the first request information RQ1 differs from the operation of the locking / unlocking device 31 specified by the second request information RQ (STEP 2).

[0030] If it is determined that the operation of the locking / unlocking device 31 specified by the first request information RQ1 differs from the operation of the locking / unlocking device 31 specified by the second request information RQ (YES in STEP 2), the processing unit 142 executes arbitration processing to invalidate either the first request information RQ1 or the second request information RQ2 (STEP 3). As a result, either the operation of the locking / unlocking device 31 specified by the first request information RQ1 or the operation of the locking / unlocking device 31 specified by the second request information RQ is made valid.

[0031] Next, the processing unit 142 outputs a control signal CS for causing the locking / unlocking device 31 to perform one of the enabled operations from the output unit 123 (STEP 4). The locking / unlocking device 31 executes the operation based on the control signal CS.

[0032] For example, when the first request information RQ1 requests the locking / unlocking device 31 to lock the doors and the second request information RQ2 requests the locking / unlocking device 31 to unlock the doors, and the first request information RQ1 and the second request information RQ2 are simultaneously received by the reception unit 141, arbitration processing is executed. If the first request information RQ1 is determined to be valid as a result, the locking / unlocking device 31 locks the doors.

[0033] According to this configuration, the control device 14 that controls the operation of the locking / unlocking device 31 can be provided with an arbitration function for different operation requests for the locking / unlocking device 31 wirelessly transmitted from multiple mobile devices. In other words, when different requests for the operation of the locking / unlocking device 31 are made from multiple mobile devices, none of the requests will be rejected, and one of the requests will always be adopted. This improves the convenience of the authentication system 10 that can remotely control the operation of the locking / unlocking device 31 using multiple mobile devices.

[0034] If the first request information RQ1 and the second request information RQ2 are not simultaneously received by the receiving unit 141 (NO in STEP 1), as described above, a control signal CS corresponding to the received request is output (STEP 4).

[0035] Also, when the first request information RQ1 and the second request information RQ2 are simultaneously received by the receiving unit 141, and it is determined that the operation of the locking / unlocking device 31 specified by the first request information RQ1 matches the operation of the locking / unlocking device 31 specified by the second request information RQ (NO in STEP 2), a control signal CS corresponding to the received request is output (STEP 4).

[0036] 4 shows an example of an arbitration process executed by the processing unit 142 of the control device 14. In this example, the processing unit 142 is configured to cause the locking / unlocking device 31 to perform an operation designated by the request information that is accepted earlier by the acceptance unit 141.

[0037] In the illustrated example, at time t1, first request information RQ1 specifying a locking operation is received from the first mobile device 11, and at time t2, which is later than time t1, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12. In this case, the processing unit 142 validates the first request information RQ1 received earlier, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform a locking operation.

[0038] Similarly, at time t3, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12, and at time t4, which is later than time t3, first request information RQ1 specifying a locking operation is received from the first mobile device 11. In this case, the processing unit 142 validates the second request information RQ2 received earlier, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform an unlocking operation.

[0039] 5 shows another example of the arbitration process executed by the processing unit 142 of the control device 14. In this example, the processing unit 142 is configured to cause the locking / unlocking device 31 to perform an operation designated by the request information accepted later by the accepting unit 141.

[0040] In the illustrated example, at time t1, first request information RQ1 specifying a locking operation is received from the first mobile device 11, and at time t2 later than time t1, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12. In this case, the processing unit 142 validates the second request information RQ2 received later, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform an unlocking operation.

[0041] Similarly, at time t3, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12, and at time t4, which is later than time t3, first request information RQ1 specifying a locking operation is received from the first mobile device 11. In this case, the processing unit 142 validates the first request information RQ1 received later, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform a locking operation.

[0042] 6 shows another example of the arbitration process executed by the processing unit 142 of the control device 14. In this example, the processing unit 142 is configured to adopt a request that may change the current state of the locking / unlocking device 31. The processing unit 142 may determine the current state of the locking / unlocking device 31 based on the operation of the locking / unlocking device 31 associated with the last output control signal CS.

[0043] In the illustrated example, with the locking / unlocking device 31 locking the door, first request information RQ1 specifying a locking operation is received from the first mobile device 11 at time t1, and second request information RQ2 specifying an unlocking operation is received from the second mobile device 12 at time t2, which is later than time t1. In this case, the processing unit 142 validates the second request information RQ2 that can change the current state of the locking / unlocking device 31, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform an unlocking operation.

[0044] On the other hand, with the locking / unlocking device 31 unlocking the door, first request information RQ1 specifying a locking operation is received from the first mobile device 11 at time t3, and second request information RQ2 specifying an unlocking operation is received from the second mobile device 12 at time t4, which is later than time t3. In this case, the processing unit 142 validates the first request information RQ1 that can change the current state of the locking / unlocking device 31, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform an unlocking operation.

[0045] According to such a configuration, it is possible to avoid a situation in which a request that cannot change the state of the locking / unlocking device 31 is given priority and an effective request is rejected.

[0046] 7 shows another example of the arbitration process executed by the processing unit 142 of the control device 14. In this example, the processing unit 142 is configured to cause the locking / unlocking device 31 to perform an operation specified by request information transmitted from a mobile device to which a higher authority level has been assigned. As one example, between a mobile device having a master key function and a mobile device having a spare key function, a higher authority level is assigned to the mobile device having the master key function. As another example, between a mobile device owned by the owner of the vehicle 30 and a mobile device owned by a family member of the owner, a higher authority level is assigned to the mobile device owned by the owner.

[0047] Information on the authority level granted to the first mobile device 11 may be included in the first authentication information AT1 and transmitted. Similarly, information on the authority level granted to the second mobile device 12 may be included in the second authentication information AT2 and transmitted. The processing unit 142 of the control device 14 may determine which mobile device has a higher authority level, based on the first authentication information AT1 and the second authentication information AT2 accepted by the accepting unit 141.

[0048] In the illustrated example, a higher authority level is granted to the second mobile device 12. At time t1, first request information RQ1 specifying a locking operation is received from the first mobile device 11, and at time t2, which is later than time t1, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12. In this case, the processing unit 142 validates the second request information RQ2 transmitted from the second mobile device 12, which is granted a higher authority level, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform an unlocking operation.

[0049] Subsequently, at time t3, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12, and at time t4, which is later than time t3, first request information RQ1 specifying a locking operation is received from the first mobile device 11. In this case as well, the processing unit 142 validates the second request information RQ2 transmitted from the second mobile device 12, which is granted a higher authority level, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform an unlocking operation.

[0050] 8 shows another example of the arbitration process executed by the processing unit 142 of the control device 14. In this example, the processing unit 142 is configured to cause the locking / unlocking device 31 to perform an operation designated by request information transmitted from a mobile device that is more closely related to the locking / unlocking device 31.

[0051] Examples of mobile devices that can remotely control the locking / unlocking device 31 include (1) a key device that wirelessly transmits locking / unlocking signals to the communication device 13 by button operation, (2) a dedicated mobile device that is carried around and automatically authenticates with the communication device 13, and when the authentication is established, performs locking / unlocking operations when the doorknob is touched, and (3) a general-purpose mobile device in which an application having a locking / unlocking function is installed. In this case, it is assumed that the device (1) or the device (2) has a higher relevance to the locking / unlocking device 31 than the device (3).

[0052] Information regarding the association of the first mobile device 11 with the locking / unlocking device 31 may be included in the first authentication information AT1 and transmitted. Similarly, information regarding the association of the second mobile device 12 with the locking / unlocking device 31 may be included in the second authentication information AT2 and transmitted. The processing unit 142 of the control device 14 may determine which mobile device is more closely associated with the locking / unlocking device 31, based on the first authentication information AT1 and the second authentication information AT2 accepted by the accepting unit 141.

[0053] In the illustrated example, the first mobile device 11 has a higher association with the locking / unlocking device 31. At time t1, first request information RQ1 specifying a locking operation is received from the first mobile device 11, and at time t2, which is later than time t1, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12. In this case, the processing unit 142 validates the first request information RQ1 transmitted from the first mobile device 11 having the higher association, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform a locking operation.

[0054] Subsequently, at time t3, second request information RQ2 specifying an unlocking operation is received from the second mobile device 12, and at time t4, which is later than time t3, first request information RQ1 specifying a locking operation is received from the first mobile device 11. In this case as well, the processing unit 142 validates the first request information RQ1 transmitted from the first mobile device 11, which has a higher relevance, and outputs from the output unit 123 a control signal CS that causes the locking / unlocking device 31 to perform a locking operation.

[0055] The processing unit 142 of the control device 14 having the various functions described above can be realized by a general-purpose microprocessor that operates in cooperation with a general-purpose memory. Examples of the general-purpose microprocessor include a CPU, an MPU, and a GPU. Examples of the general-purpose memory include a ROM and a RAM. In this case, the ROM can store a computer program that executes the above-mentioned processing. The ROM is an example of a non-transient computer-readable medium that stores a computer program. The general-purpose microprocessor specifies at least a part of the computer program stored on the ROM, deploys it on the RAM, and executes the above-mentioned processing in cooperation with the RAM. The above-mentioned computer program may be pre-installed in the general-purpose memory, or may be downloaded from an external server device (not shown) via a wireless communication network (not shown) and then installed in the general-purpose memory. In this case, the external server device is an example of a non-transient computer-readable medium that stores a computer program.

[0056] The processing unit 142 may be realized by a dedicated integrated circuit capable of executing the above computer program, such as a microcontroller, an ASIC, or an FPGA. In this case, the above computer program is pre-installed in a storage element included in the dedicated integrated circuit. The storage element is an example of a non-transitory computer-readable medium that stores a computer program. Each processor may also be realized by a combination of a general-purpose microprocessor and a dedicated integrated circuit.

[0057] The above-described embodiments are merely examples for facilitating understanding of the present invention. The configurations according to the above-described embodiments may be modified or improved as appropriate without departing from the spirit and scope of the present invention.

[0058] The number of mobile devices capable of simultaneous wireless communication with the communication device 13 may be three or more.

[0059] In each of the above-described embodiments, the control device 14 is mounted on the vehicle 30. With such a configuration, communication delays that may occur in short-range wireless communication between the first mobile device 11 and the second mobile device 12 can be easily suppressed.

[0060] However, at least a part of the authentication process performed by the processing unit 142 of the control device 14 may be performed in an external server device (not shown) that can communicate with the first mobile device 11 and the second mobile device 12 via a wireless communication network (not shown).

[0061] The controlled device controlled by the control device 14 as a result of the authentication process is not limited to the locking / unlocking device 311. Other examples of controlled devices include an ignition power supply, an engine, an air conditioner, audiovisual equipment, lighting devices, and position adjustment mechanisms for seats and steering wheels mounted on the vehicle 30. Different requests for the operation of each controlled device are subjected to arbitration. For example, requests include starting and stopping the engine, and turning on and off the air conditioner and lighting devices. The number of operations of controlled devices that can be subjected to arbitration may be three or more.

[0062] The authentication system 10 may be applied to a moving body other than the vehicle 30. Examples of other moving bodies include trains, airplanes, ships, etc. The moving body may not require a driver.

[0063] The opening / closing body that is locked and unlocked by the locking / unlocking device 31 is not limited to the door of the mobile body. Doors and windows in a house or facility can also be examples of the opening / closing body. In other words, the communication device 131 does not need to be mounted on the mobile body.

[0064] In order to remotely control the operation of a controlled device using a mobile device carried by person 20, an authentication process does not necessarily have to be performed. [Explanation of symbols]
