  Hereinafter, the operation of the remote control system 1 of the present embodiment will be described. In this remote operation system 1, the remote operation device 3, the portable information terminal 5, and the information center 7 each have a program for realizing the following functions in a ROM or the like, and operate according to the program. These programs can be recorded on a computer-readable recording medium such as a CD, a DVD, or a hard disk.

  In the remote operation system 1 of the present embodiment, when the user voluntarily blinks or extinguishes the turn signal lamp at a position away from the vehicle (execution of the car finder function), for the prevention of theft or forgetting operation, etc. When performing a remote operation of a vehicle device such as when locking or unlocking a vehicle door, the web browser is activated by operating the input operation unit 5b of the portable information terminal 5. The information center 7 stores a format (hereinafter referred to as a remote operation request screen) for requesting a remote operation necessary for driving a vehicle device remotely by operating the portable information terminal 5.

  When an operation by the user is performed via the input operation unit 5a while the web browser is activated, the portable information terminal 5 performs wireless communication connection via the information center 7 and the communication network in accordance with the operation. The information center 7 is requested to provide a web screen for requesting remote operation of the center 7.

  Upon receiving a request from the portable information terminal 5, the information center 7 establishes communication connection with the remote control device 3 and acquires the current vehicle state information such as the open / close state of the window and the locked / unlocked state of the door. To do. Thereafter, the information center 7 provides the portable information terminal 5 with a remote operation request screen (web screen) to which the current vehicle state information is added.

  As shown in FIG. 2A, the remote operation request screen 100 to which the current vehicle state information 101 is added is displayed on the screen display unit 5a of the portable information terminal 5 that has received this remote operation request screen. At this time, the user can easily confirm the current vehicle state information 101 on the remote operation request screen 100, and can reliably and easily perform an operation instruction to the vehicle device.

  Note that the remote operation request screen 100 may be stored in advance in the ROM of the portable information terminal 5. In this case, when an input operation by the user is performed via the input operation unit 5b, the remote operation request screen 100 is displayed on the screen display unit 5a without performing communication connection with the information center 7. Further, the above-described current vehicle state information 101 indicates that the portable information terminal 5 has received information from the information center 7 when an instruction operation is performed on the operation item on the remote operation request screen 100 via the input operation unit 5b. It may be configured to obtain.

  The remote operation request screen 110 displayed on the screen display unit 5a can be remotely controlled by operating the portable information terminal 5, as shown in FIG. Operation items 111 such as closing, locking / unlocking of a vehicle door, and lighting / extinguishing of a hazard lamp may be provided. In the operation item 111, a check box 112 is provided for each operation item. The user checks the check box 112 corresponding to the desired operation item 111 on the remote operation request screen 110 via the input operation unit 5b. As a check method of the check box 112, for example, the mobile information terminal 5 checks the remote operation request screen 110 by moving the cursor on the remote operation request screen 110 and clicking on the check box 112. The presence or absence of a check on the box 112 is recognized, and it is determined whether the remote operation of any vehicle device is desired by the user. When the mobile information terminal 5 makes a transmission request with one of the check boxes 112 checked by an operation by the user, the information center indicates that the remote operation of the vehicle device corresponding to the check is requested. A remote operation request instruction is transmitted to the information center 7 to notify the information center 7.

  By the way, for example, when the window of the vehicle is open and the door of the vehicle is unlocked (open), it can be assumed in advance that the user executes an operation item for closing the window and an operation item for locking the door. . As described above, when a combination of operation items to be executed by the user is assumed in advance, if the combined operation items can be collectively executed by only a single operation by the user, each operation item is individually executed as in the past. Compared with the case where it makes it, the operation burden of a user is reduced significantly and the convenience improves.

  Therefore, a batch execution operation item 102 that can execute a predetermined combination of operation items in a batch is set in the remote operation request screens 100 and 110 of the portable information terminal 5 according to the present embodiment. That is, on the remote operation request screens 100 and 110 displayed on the screen display unit 5a, a batch execution operation item (for example, displayed as “reliable set”) 102 composed of graphics such as icons and characters is displayed by the user. By performing an instruction operation via the input operation unit 5b, a predetermined combination of operation items is collectively executed.

  Note that the operation items excluding the inappropriate state items among the operation items in a predetermined combination are actually executed. Here, the improper state item is, for example, when the operation item for closing the window, the operation item for locking the door, and the operation item for closing the slide roof are operation items in a predetermined combination, and the slide roof is already closed. May be in a state. In this case, since the operation item for closing the slide roof does not need to be executed already, it corresponds to the inappropriate state item and is not executed.

  Further, the batch execution operation item 102 may be always displayed on the remote operation request screens 100 and 110, and the number of items obtained by excluding inappropriate state items from a predetermined combination of operation items is 2 or more (however, a hazard lamp is displayed). The batch execution operation item 102 may be displayed only when the operation item is turned off.

  As described above, the operation item for closing the window, the operation item for locking the door, and the operation item for closing the slide roof are combined in a predetermined combination of operation items (in this case, the collective execution operation item 102 is set to “reliable set”. And). In addition, an operation item for closing the window and an operation item for setting the air conditioner to automatic temperature setting (or a temperature set by the user using the portable information terminal 5) and a predetermined combination of operation items (in this case, the batch execution operation item 102). May be referred to as a “comfortable set”. Further, an operation item for starting the engine, an operation item for closing the window, and an operation item for setting the air conditioner to automatic temperature setting (or a temperature set by the user using the portable information terminal 5) are combined into a predetermined combination of operation items ( In this case, the batch execution operation item 102 may be “warm air set”. These predetermined combinations of operation items are stored in advance in the database 7b of the information center 7 using a table, a map, or the like.

  The predetermined combination of operation items stored in the database 7b of the information center 7 is configured to be freely set / changed freely by an instruction operation through the portable information terminal 5 by the user. Furthermore, the predetermined combination of operation items may be stored in advance in the ROM of the portable information terminal 5 together with the remote operation request screens 100 and 110.

  Next, a processing flow when the batch execution operation item 102 is executed on the remote operation request screens 100 and 110 will be described. FIG. 3 is a flowchart showing a processing flow when the batch execution operation item 102 is executed.

  For example, as shown in FIG. 2A, the batch execution operation item 102 set on the remote operation request screens 100 and 110 of the screen display unit 5a is instructed through the input operation unit 5b, and the transmission item 103 is set. When an instruction operation is performed (hereinafter, step 1 is referred to as S1), the communication control unit 5d establishes communication connection with the information center 7. Further, the communication control unit 5d acquires a predetermined combination of operation items executed by the collective execution operation item 102 from the database 7b of the information center 7 and displays it on the screen display unit 5a. As a result, the user can reconfirm the predetermined combination of operation items executed by the batch execution operation, which leads to prevention of erroneous operations.

  At this time, the information center 7 connects to the remote control device 3 of the vehicle, and based on the information from the master ECU 3b of the remote control device 3, the hazard lamp of the vehicle is in a lighting state (the lighting state includes a blinking state). ) Is determined (S2).

  When the information center 7 determines that the hazard lamp of the vehicle is lit, as shown in FIG. 4A, the hazard lamp is turned off by the batch execution operation together with the predetermined combination of operation items 121 described above. For example, a remote operation request screen 120 displaying characters, diagrams, and animations 122 such as “Do not erase hazards with a secure set” is transmitted to the communication control unit 5 d of the portable information terminal 5. The communication control unit 5d of the portable information terminal 5 displays the received remote operation request screen 120 displaying the above-mentioned predetermined combination of operation items 121 and 122 indicating that the buzzer lamp is not turned off by the batch execution operation. It is displayed on the part 5a (S3).

  In some cases, the hazard lamp is intentionally turned on / flashed when the vehicle is stopped. For this reason, when the hazard lamp is turned off by the batch execution operation described above, the operation may be contrary to the user's intention. Therefore, the predetermined combination of operation items 121 is configured not to include a hazard lamp extinguishing operation in advance, and operation execution contrary to the user's intention is suppressed. In addition, since the operation item 121 of the predetermined combination is configured not to include the operation of turning off the hazard lamp in this way, in order to prevent an erroneous operation due to a user's misunderstanding, as described above, the buzzer lamp can be controlled by the collective execution operation. A message 122 indicating that the light is not turned off is displayed to alert the user.

  Further, the remote operation request screen 120 of the screen display unit 5a is not turned off by a predetermined combination of the operation items 121 and the batch execution operation so that the user can intentionally turn off the hazard lamp. The individual item operation 104 for turning off the hazard lamp may be set together with the display of the effect 122, for example, “the hazard lamp is turned off in addition to the above operation items”, and the operation item for turning off the hazard lamp is individually set. May be. The user can intentionally turn off the hazard lamp by instructing the individual item operation 104 or the like for turning off the hazard lamp via the input operation unit 5b.

  On the other hand, when the information center 7 determines that the hazard lamp of the vehicle is in an extinguished state, based on the determination, as shown in FIG. 4 (b), a remote operation request that displays only a predetermined combination of operation items 121 is displayed. The screen 130 is transmitted to the communication control unit 5d of the portable information terminal 5. The communication control unit 5d of the portable information terminal 5 causes the screen display unit 5a to display the received remote operation request screen 130 for only the above-described predetermined combination of operation items 121 (S4).

  Next, when the user instructs the transmission item 103 on the remote operation request screens 120 and 130 via the input operation unit 5b, the remote operation request instruction is transmitted to the information center 7 (S5).

  The information center 7 establishes a wireless communication connection with the vehicle remote control device 3 corresponding to the portable information terminal 5 via a communication network. Further, the information center 7 transmits a remote operation request instruction indicating that a remote operation of a specific vehicle device is requested by an operation of the portable information terminal 5 to the remote operation device 3.

  The DCM 3a of the remote operation device 3 receives the remote operation request instruction transmitted from the information center 7 via the communication network and the data communication antenna 3c, and the master ECU 3b performs the remote operation of the vehicle device for which the remote operation is requested. In order to implement, a signal (operation instruction) requesting that the vehicle device should be remotely operated is transmitted to the slave ECU 3d that drives the vehicle device.

  When the slave ECU 3d receives the operation instruction from the master ECU 3b, the slave ECU 3d performs a process for executing a remote operation of the corresponding vehicle device. For example, when the slave ECU 3d receives an operation instruction signal for door lock from the master ECU 3b, the slave ECU 3d performs an operation for switching all vehicle doors from the unlocked state to the locked state.

  As described above, in the remote operation request screens 100 and 110 of the portable information terminal 5 according to the present embodiment, the batch execution operation item 102 that can collectively execute the predetermined combination of the operation items 121 that can be predicted to be executed by the user. Is set. The user can easily execute remote operations of a plurality of vehicle devices only by instructing the batch execution operation item 102. Therefore, the user's operation burden is greatly reduced, and convenience is improved.

  Further, in the portable information terminal 5 according to the present embodiment, the predetermined combination of operation items 121 is configured not to include an operation item for turning off the hazard lamp in advance. Further, when it is determined that the hazard lamp of the vehicle is in a lighting state, a remote operation request screen displaying 122 indicating that the buzzer lamp is not turned off by the batch execution operation together with the operation item 121 of the predetermined combination described above. 120 is transmitted to the communication control unit 5d of the portable information terminal 5 and displayed on the screen display unit 5a. Accordingly, it is possible to prevent the hazard lamp from being turned off against the user's intention, and at the same time, the user is surely recognized that the hazard lamp is not turned off in advance, and the misunderstanding in operation is eliminated.

  In the remote operation system 1 of the present embodiment, the user operates the portable information terminal 5 to make a remote operation request from the portable information terminal 5 to the remote operation device 3 via the information center 7. The mounted vehicle equipment is operated remotely. For this reason, the user can drive the vehicle device by operating the portable information terminal 5 at a place away from the vehicle even if the user is not on the vehicle. As a result, the vehicle device can be remotely transferred to a desired state.

  As mentioned above, although the best mode for carrying out the present invention has been described using one embodiment, the present invention is not limited to such one embodiment, and within the scope not departing from the gist of the present invention, Various modifications and substitutions can be made to the above-described embodiment.

  For example, in the above-described embodiment, on the remote operation request screen 110, a predetermined combination of the operation items 111, the corresponding check boxes 112, and the batch execution operation items (for example, the security set) 102 are displayed on separate screens. Alternatively, as shown in FIG. 2B, they may be displayed simultaneously on the same screen. In this case, only by the user selecting and instructing the batch execution operation item 102, a check is automatically input to the check box 112a corresponding to a predetermined combination of operation items as shown in FIG. (However, the operation item 112b for turning off the hazard lamp is excluded). Thereafter, the transmission item 103 on the remote operation request screen 140 is instructed, and the remote operation request screen 140 is transmitted from the portable information terminal 5 to the information center 7. Further, as shown in FIG. 5B, an operation confirmation screen 150 for confirming the operation content may be returned from the information center 7 to the portable information terminal 5 to prevent erroneous operation.

  In the embodiment described above, when an instruction operation (instruction operation by the individual item operation 104 or the like) for canceling an operation of closing a window, a slide roof or the like is performed on the remote operation request screens 100 and 110 of the portable information terminal 5, for example, The display unit 5a may display a warning screen based on environmental information such as weather information around the vehicle detected by the environmental information detection unit 9. Specifically, information for calling attention such as “It is raining around the vehicle” may be provided on the screen. The environmental information detection means 9 is disposed on load information from a load sensor disposed on the hood of the vehicle, image information around the vehicle photographed by the camera, inter-vehicle communication with other vehicles, or on the road. For example, weather information such as rainfall, snowfall, outside air, wind speed, and the like is detected on the basis of, for example, driving information of a wiper device of another vehicle acquired by road-to-vehicle communication with a communication device. The weather information detected by the environment information detection means 9 is transmitted to the information center 7 via the vehicle remote control device 3. For example, when the information center 7 is instructed to cancel the operation of closing the window, the slide roof, etc., and further determines that the weather around the vehicle is rain, snow, etc., the information center 7 displays “ A warning message such as “It is raining around the vehicle” is added and transmitted to the portable information terminal 5. Thereby, the user can perform a remote operation of the vehicle in consideration of the weather information.

  In the above-described embodiment, the above-described caution display for alerting the user that the buzzer lamp is not turned off may be displayed on the remote operation request screen 100 together with the current vehicle state information 101. Thereby, the user can perform an operation based on the precautions when confirming the vehicle state information. In this case, the reconfirmation 122 after the collective execution operation may be omitted.

  In addition, the above-described caution display for alerting the operator that the hazard lamp is not turned off is changed when the state of each operation item is changed (for example, the hazard lamp is changed from the turn-off operation to the lighting operation).
