  Hereinafter, the best mode for carrying out the present invention will be described in several embodiments with reference to the drawings.

  FIG. 1 is a diagram showing a configuration example of a remote control system according to the present invention. The remote operation system 100 includes an in-vehicle terminal device V, a communication center C, and an operation terminal M.

  Wireless communication is performed between the in-vehicle terminal device V and the communication center C using a mobile phone frequency or the like, and between the communication center C and the operation terminal M is wireless communication using a mobile phone frequency or the like using an optical cable or a coaxial cable. Wired communication is performed. Note that direct communication may be performed between the in-vehicle terminal device V and the operation terminal M by specific power-saving radio.

  The in-vehicle terminal device V includes a control unit V1, a transceiver V2, and a position detection device V3, and is connected to the light emitter control device V4 and the acoustic control device V5.

  The control unit V1 is a computer including a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an NVRAM (Non-Volatile RAM), and the like.

  The transceiver V2 is a device used for communication between the in-vehicle terminal device V and the communication center C, or between the in-vehicle terminal device V and the operation terminal M, and the operation terminal M via the communication center C using a mobile phone frequency. Or direct communication with the operation terminal M by a specific power-saving radio having an operation range of tens to thousands of meters.

  The position detection device V3 is a device for detecting vehicle position information. For example, the position detection device V3 determines the vehicle position (latitude, longitude, altitude) based on a GPS signal output from a GPS satellite via a GPS antenna by a GPS receiver. Position and calculate. The positioning method may be any method such as independent positioning or relative positioning (including interference positioning), but preferably relative positioning with high accuracy is used. At this time, the vehicle position may be corrected based on outputs of various sensors such as a steering angle sensor, a vehicle speed sensor, and a gyro sensor, and various information received via the beacon receiver and the FM multiplex receiver.

  The light emitter control device V4 is an in-vehicle device that controls lighting and extinction of light emitters such as a hazard lamp, a brake lamp, a headlight, a parking light, and an indoor light in response to a remote operation request from the operation terminal M.

  The acoustic control device V5 is a device that controls an acoustic device such as a horn, a buzzer, or a vehicle-mounted speaker in response to a remote operation request from the operation terminal M.

  Here, the “remote operation request” means that the operation terminal M causes the communication center C (in order to cause the in-vehicle device such as the light emitter control device V4 and the acoustic control device V5 connected to the in-vehicle terminal device V to execute a predetermined operation. This signal is transmitted to the in-vehicle terminal device V), and may consist of only a remote operation request for one in-vehicle device, or may consist of remote operation requests for a plurality of in-vehicle devices.

  Functions that can be used by remote operation include, for example, a car finder function for notifying a vehicle position to the surroundings by causing a light emitter to emit light by the light emitter controller V4 or generating sound from the acoustic device by the sound controller V5. , Door control function to unlock and lock the door, engine start function to start the engine for a certain period of time for warm-up operation, vehicle interior temperature control function to control the temperature in the vehicle interior by operating the air conditioner, vehicle interior by direct sunlight There is a sunshade function for operating the sunshade so that the temperature does not rise.

  The communication center C is a facility for relaying communication between the in-vehicle terminal device V and the operation terminal M, and includes a control unit C1 and a transceiver C2. The control unit C1 is in-vehicle as in the control unit V1. This is a computer capable of executing predetermined arithmetic processing based on information from the terminal device V or information from the operation terminal M.

  The operation terminal M is a device for remotely operating the in-vehicle device. For example, the operation terminal M is an operation terminal such as a mobile phone, a PHS (Personal Handyphone System), a notebook personal computer, a transceiver, etc. Although it is possible, it may be an operation terminal such as a desktop computer or a dedicated console, which is connected to the communication center C by wire via the Internet.

  The operation terminal M includes a control unit M1, a transceiver M2, a display device M3, and a position detection device M4. The control unit M1 is a computer including a CPU, RAM, ROM, NVRAM, and the like, similar to the control unit V1 of the in-vehicle terminal device V, and the transceiver M2 is used for communication between the in-vehicle terminal device V and the communication center C. Used.

  The display device M3 is a device for displaying information from the in-vehicle terminal device V and the communication center C, and is, for example, an LCD (Liquid Crystal Display) or an organic EL (ElectroLuminescence) display.

  The position detection device M4 is a device for detecting the position information of the operation terminal M. For example, the position detection device M4 is operated based on a GPS signal output from a GPS satellite by a GPS receiver, similarly to the position detection device V3 of the in-vehicle terminal device V. Measure and calculate the terminal position (latitude, longitude, altitude).

  Next, referring to FIG. 2 showing a configuration example of the control unit V1 in the in-vehicle terminal device V, the authentication unit V10, the remote operation execution unit V11, the authentication necessity determination unit V12 included in the control unit V1 of the in-vehicle terminal device V, Vehicle position information acquisition means V13, operation terminal position information acquisition means V14, and execution result notification means V15 will be described.

  The authentication unit V10 is a unit for authenticating an operator who operates the operation terminal M. For example, an authentication screen is distributed to the operation terminal M to allow the operator to input a password, and an appropriate password is input. To authenticate the operator.

  The authentication means V10 may authenticate the operator based on the voice print of the voice uttered by the operator, and reads the operator's vein pattern or fingerprint by a dedicated reading device mounted on the operation terminal M to identify the operator. Alternatively, authentication may be performed, or an operator may be photographed by a camera mounted on the operation terminal M, and the operator may be authenticated by recognizing an iris (a pattern outside the pupil) or a face.

  The remote operation execution means V11 is a means for executing an operation of the in-vehicle device in response to a remote operation request from the operation terminal M. For example, the light emitter control device V4 causes a hazard lamp to be operated for a predetermined time (for example, 2 minutes). It blinks or the sound control device V5 sounds the horn intermittently at a predetermined interval (for example, 30 seconds).

  The authentication necessity determination means V12 performs another remote operation by the remote operation execution means V11 when receiving another remote operation request via the operation terminal M from the operator who has already been authenticated and executed the remote operation. This is a means for determining whether or not to request re-authentication of the operator before execution. For example, the elapsed time from when the operator who has already been authenticated first makes a remote operation request is a predetermined time ( For example, until it exceeds 24 hours), it is determined that re-authentication of the operator is not necessary, and the remote operation is executed by the remote operation execution means V11. The elapsed time may be an elapsed time from the time when the authentication of the operator is performed by the authentication unit V10 or the time when the operation terminal M receives the execution result of the remote operation.

  If it is within the predetermined time, it can be assumed that the remote operation request has already been made by an operator who has already been authenticated, and while maintaining a certain level of security, processing related to authentication such as authentication screen distribution and password entry can be omitted. This is because the convenience for the operator can be improved.

  The remote operation in this case may be limited to functions that do not cause a security problem even if executed, such as a car finder function or a sunshade function. This is because when the door is unlocked by remote operation without the operator's authentication like the door control function, the vehicle may be stolen.

  The authentication necessity determination unit V12 determines that the operator does not need to be re-authenticated when the distance between the operation terminal M and the in-vehicle terminal device V (vehicle) is less than a predetermined value, and executes the remote operation. The remote operation may be executed by the means V11. This is because the operator is present in the vicinity of the vehicle, so that it can be estimated that the remote operation request is issued by the operator who has already been authenticated.

  Further, the authentication necessity determination unit V12 performs re-authentication of the operator when the distance between the operation terminal M and a predetermined position (for example, work or home) is less than a predetermined value (for example, 100 meters). It may be determined that it is not necessary, and the remote operation execution means V11 may execute the remote operation. This is because the operation terminal M (operator) is close to home or the like, so that it can be estimated that the remote operation request is issued by an already authenticated operator.

  On the contrary, the authentication necessity determination means V12 determines that the operator needs to be re-authenticated when the operation terminal M is within a predetermined geographical area (for example, a downtown area), and performs remote operation. In order to execute remote operation by means V11, re-authentication of the operator by inputting a password or the like may be requested. This is because it is considered that there are relatively many opportunities for theft and security is not deteriorated.

  Further, the authentication necessity determination unit V12 may determine that the re-authentication of the operator is not required during a predetermined time zone or day of the week, and may cause the remote operation execution unit V11 to execute the remote operation. This is to balance security and convenience according to the behavior pattern of the operator.

  The vehicle position information acquisition means V13 is a means for acquiring information related to the vehicle position. For example, the vehicle position information acquisition means V13 receives a signal from the position detection device V3 and acquires information related to the vehicle position.

  The operation terminal position information acquisition unit V14 is a unit for acquiring information about the operation terminal position. For example, the operation terminal position information acquisition unit V14 receives a signal from the position detection device M4 and acquires information about the operation terminal position.

  The execution result notification means V15 is means for notifying the operation terminal M of the execution result of the remote operation executed by the in-vehicle terminal device V in response to the remote operation request. For example, the fact that the car finder function has been appropriately executed Alternatively, the operation terminal M is notified by e-mail that the car finder function could not be executed due to the failure of the light emitter control device V4.

  The execution result notification means V15 may notify the operation terminal M by attaching a hyperlink that prompts re-execution of remote operation (for example, a car finder function) to an electronic mail. This is to improve the convenience of the operator, and when the authentication necessity determination means V12 determines that re-authentication is not necessary, the operator can re-execute the car finder function with a single click operation. .

  The execution result notifying means V15 attaches a hyperlink that prompts re-execution only when notifying that the execution result of the preceding remote operation has been properly executed, and the execution result of the preceding remote operation is appropriate. When notifying that it could not be executed, a hyperlink that prompts re-execution may not be attached. This is because the operation is wasted when the execution is attempted again unless the problem that causes the failure (for example, the failure of the light emitter control device V4) is solved.

  Next, with reference to FIG. 3, transmission / reception of signals between the operation terminal M, the communication center C, and the in-vehicle terminal device V, and processing executed in the operation terminal M, the communication center C, and the in-vehicle terminal device V will be described. To do.

  FIG. 3 shows the passage of time from the upper part of the drawing to the lower part of the drawing, showing the contents of processing executed by the operation terminal M at the left end, the communication center C at the center, and the in-vehicle terminal device V at the right end. Indicates transmission and reception.

  First, the operation terminal M transmits a remote operation request to the vehicle terminal device V via the communication center C in order to execute a remote operation (for example, a car finder function) (SG1). When receiving the remote operation request, the in-vehicle terminal device V determines whether or not the operator needs to be authenticated by the authentication necessity determination unit V12 (P1). Since this remote operation request is transmitted for the first time from the operation terminal M, it is determined by the authentication necessity determination means V12 that authentication is required, and the in-vehicle terminal device V makes an authentication request to the operation terminal M (SG2). .

  Receiving the authentication request, the operating terminal M displays an authentication screen on the display device M3, requests the operator to input a password, and transmits the input password to the in-vehicle terminal device V (SG3).

  The in-vehicle terminal device V receives the password and determines whether or not the password is appropriate. If the password is appropriate, the in-vehicle terminal device V determines that the operator has been authenticated and performs the car finder function in response to the remote operation request. Execute (P2). On the other hand, when the password is inappropriate, the in-vehicle terminal device V notifies the operation terminal M that the password is inappropriate without executing the car finder function.

  When there are a plurality of functions that can be remotely operated, the in-vehicle terminal device V that authenticates the operator by receiving an appropriate password causes the operation terminal M to transmit a remote operation menu screen and select a remote operation to be executed. May be. In this case, the operator selects a desired remote operation (car finder function) on the operation terminal M, and transmits the selection content to the in-vehicle terminal device V. And the vehicle-mounted terminal device V which received the selection content transmits the confirmation screen for confirming that the content which the runner selected is correct to the operation terminal M. The operator confirms that the content of the remote operation selected by the operator on the confirmation screen displayed on the display device M3 of the operation terminal M is the car finder function, and transmits a final execution command to the in-vehicle terminal device V. Thereafter, the in-vehicle terminal device V that has received the execution command executes the car finder function.

  After executing the car finder function, the in-vehicle terminal device V notifies the operation terminal M of the execution result of the car finder function by the execution result notifying means V15 (SG4). The execution result is notified to the operation terminal M in the form of an e-mail with a hyperlink that prompts re-execution of the car finder function together with a message notifying whether or not the car finder function is functioning normally (see FIG. 4). .)

  If the operator clicks on a hyperlink that prompts the car finder function to be re-executed before a predetermined time (for example, 24 hours) has elapsed since the execution result notification is received, the operation terminal M sends a remote operation request to the vehicle. It transmits to the terminal device V (SG5).

  The in-vehicle terminal device V that has received the remote operation request again determines whether or not the operator needs to be authenticated by the authentication necessity determination unit V12 (P3). Since this remote operation request is retransmitted within a predetermined time (for example, 24 hours) after the operation terminal M receives the notification of the execution result, it is determined by the authentication necessity determination means V12 that authentication is not necessary, The terminal device V executes the car finder function without requesting operator authentication (P3), and notifies the operation terminal M of the execution result of the car finder function (SG6).

  With this configuration, the remote support system 100 originally distributes the authentication screen to the operation terminal M and requests input of a password, but the processing can be omitted, thereby reducing the burden on the operator. The amount of communication between the operation terminal M and the vehicle terminal device V can be reduced.

  In addition, there are a plurality of functions that can be remotely operated, and among them, when it is desired to execute the car finder function again, originally, the authentication screen is distributed by the in-vehicle terminal device V, the password is input by the operator, the in-vehicle terminal device V The remote support system 100 distributes the remote operation menu screen, selects the remote operation by the operator, distributes the confirmation screen by the in-vehicle terminal device V, and final confirmation by the operator. Therefore, the burden on the operator can be greatly reduced, and the amount of communication between the operation terminal M and the in-vehicle terminal device V can be greatly reduced.

  On the other hand, when the operator clicks a hyperlink that prompts the car finder function to be re-executed after a predetermined time (24 hours) has elapsed from the time when the notification of the execution result is received, the operation terminal M sends a remote operation request to the in-vehicle terminal. It transmits to the apparatus V (SG7).

  The in-vehicle terminal device V that has received the remote operation request again determines whether or not the operator needs to be authenticated by the authentication necessity determination unit V12 (P4). Since this remote operation request is retransmitted after a predetermined time (for example, 24 hours) has elapsed since the operation terminal M received the notification of the execution result, it is determined that authentication is required by the authentication necessity determination unit V12. The in-vehicle terminal device V makes an authentication request to the operation terminal M (SG8).

  After that, similarly to the above-described processing, the operation terminal M that has received the authentication request displays an authentication screen on the display device M3, requests the operator to input a password, and sends the input password to the in-vehicle terminal device V. Transmit (SG9). Further, the in-vehicle terminal device V receives the password, determines whether or not the password is appropriate, and if the password is appropriate, the in-vehicle terminal device V determines that the operator can be authenticated and responds to the remote operation request by the car finder. The function is executed (P5), and the execution result is notified to the operation terminal M (SG10).

  With this configuration, the remote support system 100 permits the omission of re-authentication only for a predetermined time, so that it is possible to prevent abuse of remote operation by a third party when the operation terminal M is lost. In addition, it is possible to prevent an authenticated operator from re-executing the remote operation after a predetermined time has elapsed since the notification of the execution result was received.

  Next, the notification contents of the execution result displayed on the display device M3 of the terminal device M will be described with reference to FIG. The example of the execution result shown in FIG. 4 is for the case where the car finder function is functioning normally. The message indicating that the car finder function is functioning normally, the date and time when the car finder function was executed, the car finder function It consists of a message for prompting re-execution, a hyperlink for re-execution, a message for prompting detailed browsing of execution results, and a hyperlink for detailed browsing.

  The hyperlink for re-execution and the hyperlink for detailed browsing are displayed in an underlined state, and are differentiated from normal messages.

  The details of the execution result are, for example, the number of executions of the car finder function executed without re-authentication, the date and time when the previous car finder function was executed, and the like.

  With the above configuration, the remote operation system 100 can be used only when a predetermined temporal or spatial condition is satisfied when an operator who has been once authenticated and executed a remote operation tries to execute the remote operation again. Since the remote operation can be executed without requesting re-authentication, the convenience of the operator can be improved while ensuring a certain level of security.

  FIG. 5: is performed in the remote control system which concerns on Example 2 by transmission / reception of the signal between the operation terminal M, the communication center C, and the vehicle-mounted terminal device V, and the operation terminal M, the communication center C, and the vehicle-mounted terminal device V. FIG. 4 is a diagram for explaining the processing, showing the passage of time from the upper part of the drawing to the lower part of the drawing, showing the contents of processing executed by the operation terminal M at the left end, the communication center C at the center, and the in-vehicle terminal device V at the right end. Signal transmission / reception is indicated by arrows in between.

  In the first embodiment, the authentication means V10, the remote operation execution means V11, the authentication necessity determination means V12, the vehicle position information acquisition means V13, the operation terminal position information acquisition means V14, which are arranged in the control unit V1 of the in-vehicle terminal device V, and The execution result notifying unit V15 includes an authentication unit C10, a remote operation execution unit C11, an authentication necessity determination unit C12, a vehicle position information acquisition unit C13, an operation terminal position information acquisition unit C14, and an execution result notification unit C15. It is assumed that it is arranged in the C control unit C1.

  First, the operation terminal M transmits a remote operation request to the communication center C in order to execute a remote operation (for example, a car finder function) (SG11). Upon receiving the remote operation request, the communication center C determines whether or not the operator needs to be authenticated by the authentication necessity determination unit C12 (P11). Since this remote operation request is transmitted for the first time from the operation terminal M, the authentication necessity determination means C12 determines that authentication is necessary, and the communication center C makes an authentication request to the operation terminal M (SG12).

  Receiving the authentication request, the operating terminal M displays an authentication screen on the display device M3, requests the operator to input a password, and transmits the input password to the communication center C (SG13).

  The communication center C receives the password and determines whether or not the password is appropriate. If the password is appropriate, the communication center C determines that the operator has been authenticated (P12) and sends a remote operation request to the in-vehicle terminal device V. (SG14), and the vehicle-mounted terminal device V is caused to execute the car finder function (P13). On the other hand, when the password is inappropriate, the communication center C notifies the operation terminal M that the password is inappropriate without transmitting a remote operation request to the in-vehicle terminal device V.

  After causing the in-vehicle terminal device V to execute the car finder function and receiving the execution result from the in-vehicle terminal device V, the communication center C sends the execution result (see FIG. 4) to the operation terminal M by the execution result notifying unit C15. In addition, the vehicle position information acquired by the vehicle position information acquisition means C13 via the position detection means V3 of the in-vehicle terminal device V is notified to the operation terminal M (SG15).

  When the operator clicks a hyperlink that prompts the car finder function to be re-executed, the operation terminal M transmits the remote operation request and the operation terminal position information detected by the position detection means M4 to the communication center C (SG16, SG19). ).

  The communication center C that has received the remote operation request again and the operation terminal position information determines whether or not the operator needs to be authenticated by the authentication necessity determination unit C12 (P14 and P16).

  The authentication necessity determination means C12 is based on the vehicle position information acquired by the vehicle position information acquisition means C13 and the operation terminal position information acquired by the operation terminal position detection means C14 via the position detection means M4 of the operation terminal M. The distance between the in-vehicle terminal device V (vehicle) and the operation terminal M is calculated, and when the calculated distance is less than a predetermined value (for example, 30 m), it is determined that the operator authentication is not required (P14). ).

  When it is determined by the authentication necessity determination means C12 that the operator is not required to be authenticated, the communication center C transmits a remote operation request to the in-vehicle terminal device V (SG17), and causes the in-vehicle terminal device V to execute the remote operation. (P15). Thereafter, the communication center C notifies the operation terminal M of the execution result and the vehicle position information by the execution result notifying unit C15 (SG18).

  On the other hand, if the calculated distance is greater than or equal to a predetermined value (for example, 30 m), the authentication necessity determination unit C12 determines that the operator needs to be authenticated (P16).

  If it is determined by the authentication necessity determination means C12 that authentication is necessary, the communication center C makes an authentication request to the operation terminal M (SG20), and the operation terminal M that has received the authentication request sends it to the display device M3. The authentication screen is displayed, the operator is requested to input a password, and the input password is transmitted to the communication center C (SG21).

  The communication center C receives the password and determines whether or not the password is appropriate. If the password is appropriate, the communication center C determines that the operator has been authenticated (P17) and sends a remote operation request to the in-vehicle terminal device V. (SG22), and makes the in-vehicle terminal device V execute the car finder function (P18). Thereafter, the communication center C notifies the operation terminal M of the execution result and the vehicle position information by the execution result notification means C15 (SG23).

  With the above configuration, the remote operation system according to the second embodiment operates within a predetermined geographical range from the vehicle when an operator who has once been authenticated and executed the remote operation tries to execute the remote operation again. As long as the terminal M exists, the remote operation can be executed without requiring re-authentication, so that the convenience of the operator can be improved while ensuring a certain level of security.

  The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the present invention. Can be added.

  For example, in the above-described embodiment, the authentication necessity determination unit V12 in the in-vehicle terminal device V determines whether or not authentication is necessary based on the elapsed time from when the operation terminal M receives the notification of the execution result of the remote operation. The remote operation request via the hyperlink attached to the e-mail is based on the elapsed time from the time when the operation terminal M received the execution result by the hyperlink limiting means arranged in the control unit M1 of the operation terminal M.
