(Operation of the vehicle operating device 1)
FIG. 3 is an example of an execution function table for each scene (scene). In this example, the collective operation registration unit 220 registers scene 1 assigned to the switch 101 shown in FIG. 1, scene 2 assigned to the switch 102, and scene 3 assigned to the switch 103, for example.

  Scene 1 is assumed to get off at home. In such a situation, the windows of all seats are closed, the wiper operation is turned off, the sunshade is opened, and the door is unlocked. The user can execute such functions all at once by simply touching the switch 101 whose display unit 101a is lit, and the user can open the door and get off.

  Scene 2 assumes refueling at a gas station. In such a situation, the D seat window is opened, the wiper operation is turned off, the light is turned off, the audio is turned off, and the fuel lid is opened. The user can execute such functions all at once by simply touching the switch 102 whose display unit 102a is lit, and can send a refueling instruction from the opened window.

  Scene 3 assumes a product order by drive-through. In such a scene, the seat D window is opened and the audio output is muted. The user can execute such a function in a lump by simply touching the switch 103 whose display unit 103a is lit, and can send an instruction to order a product from the opened window.

  However, in the scene as described above, there may be a case where it is desired to delete (change) the function execution of a specific in-vehicle device from the batch operation item. For example, in scene 1, when it is scheduled to get on again after getting off, there is a case where it is desired not to close the windows of all seats. Or, in scene 2, there may be cases where it is desired not to turn off the audio. In such a case, the function execution of a specific in-vehicle device is deleted by voice input. That is, the function can be customized with a simple operation (voice input).

  FIG. 4 is a flowchart showing the operation of the vehicle operating device according to the embodiment of the present invention. Hereinafter, description will be given according to this flowchart.

  Scene determination unit 210 of operating device ECU 200 determines whether or not a collective operation condition is satisfied. It is determined whether or not the pre-registered scenes 1 to 3 satisfy the collective operation condition (Step 1). As a condition of the scene 1, by acquiring the position information of the GPS unit 310, it is determined from the previously registered map information whether the vehicle 5 is located at the registered home. Further, by acquiring the speed of the vehicle 5 by the vehicle speed sensor 320, it is determined whether or not the vehicle 5 is stopped. If both conditions are satisfied, it is determined that the condition of scene 1 is satisfied. As a condition of the scene 2, by acquiring the position information of the GPS unit 310, it is determined from the previously registered map information whether the vehicle 5 is located at the registered gas station. Further, by acquiring the speed of the vehicle 5 by the vehicle speed sensor 320, it is determined whether or not the vehicle 5 is stopped. If both conditions are satisfied, it is determined that the condition of scene 2 is satisfied. As a condition of the scene 3, by acquiring the position information of the GPS unit 310, it is determined from the previously registered map information whether the vehicle 5 is located at the registered drive-through store. Further, by acquiring the speed of the vehicle 5 by the vehicle speed sensor 320, it is determined whether or not the vehicle 5 is stopped. If both conditions are satisfied, it is determined that the condition of scene 3 is satisfied. If the registered scene condition is satisfied, the process proceeds to Step 2 assuming that the condition for the batch operation is satisfied. If not satisfied, Step 1 is repeatedly executed.

  Next, the control unit 230 of the operating device ECU 200 turns on the display units (101a, 102a, 103a) of the switches 101, 102, 103 of the collective operation switch unit 100 (Step 2). For example, in Step 1, when it is determined that the conditions for the batch operation are satisfied by considering the conditions of the scene 1, the display unit 101a of the switch 101 is turned on. If it is determined that the condition for the batch operation is satisfied by considering the conditions of the scene 2, the display unit 102a of the switch 102 is turned on. If it is determined that the conditions for the batch operation are satisfied based on the conditions of the scene 3, the display unit 103a of the switch 103 is turned on.

  Next, the control unit 230 of the controller device ECU 200 determines whether the lit switches (101, 102, 103) are touched. The switches (101, 102, 103) are capacitive touch switches, and it is possible to determine whether or not a touch operation has been performed on the switches by detecting the amount of change in the capacitance (Step 3). . When the touch operation is performed, the process proceeds to Step 4, and when the touch operation is not performed, the process proceeds to Step 5.

  When touched operation of the lit switch is performed, the control unit 230 of the operating device ECU 200 executes collective operation of the in-vehicle devices assigned corresponding to the touched switch. That is, the control unit 230 executes a plurality of in-vehicle devices registered in the storage unit 250 as registered function items via the in-vehicle LAN (Step 4). In the scene 1 batch operation, the windows of all seats are closed, the wiper operation is turned off, the sunshade is opened, and the door is unlocked. In the batch operation of scene 2, the window of the D seat is opened, the wiper operation is turned off, the light is turned off, the audio is turned off, and the fuel lid is opened. In the batch operation of scene 3, the seat D window is opened and the audio / audio output is muted. By executing the collective operation as described above, this flow ends (end).

  Control unit 230 of operating device ECU 200 determines whether or not the lit switches (101, 102, 103) have been touched for a long time. A long touch can be determined based on whether or not a touch time longer than the time set for a long time is detected with respect to the normal touch operation time (Step 5). When the long touch operation is performed, the process proceeds to Step 6, and when the touch operation is not performed, the flow ends (end).

  The operation of the control unit 230 turns on the voice input unit (voice recognition unit) 240 and the microphone 260 and transitions to the voice input mode (Step 6). In this voice input mode, the voice input unit (voice recognition unit) 240 acquires the voice uttered by the user with the microphone 260.

  Next, the voice input unit (speech recognition unit) 240 selects a phrase that matches a previously stored phrase by voice recognition processing, and recognizes a specific item of an operation corresponding to the phrase (Step 7). When the voice input unit (voice recognition unit) 240 recognizes the specific item, the process proceeds to Step 8, and when the specific item is not recognized, the flow ends (END).

  The control unit 230 deletes the recognized specific item from the batch operation item. The control unit 230 executes the batch operation item changed by deleting the specific item from the batch operation item (Step 8). For example, when the word “door unlock” is recognized by the voice input unit 240, the door lock operation is deleted from the batch operation item. In addition, it uses advanced speech recognition technology that divides the sentence "Do not close the window" and performs speech recognition processing for each section, and selects words corresponding to speech information from candidate words based on the results. It is also possible.

  With the series of flows as described above, the operation of the vehicle operating device according to the embodiment of the present invention ends (end).
