(1-6) Passenger on front seat Capable of performing open or close operations of the sunroof 40 by the sunroof switch 42, and open or close operations of the sunshade 41 by the sunroof switch.


Furthermore, as will be described later, the window control unit 72 performs open or close operations of each of the windows 11, 16, 21, 26, 40, and the sunshade 41 in accordance with open or close instructions of the windows by the voice of the passengers.


The second control device 90 is a control unit configured with a second processor 100, a second memory 110, and the like. The second processor 100 functions as a voice recognition unit 101, a window open or close instruction recognition unit 102, a window lock information saving unit 103, a window operation restriction unit 104, and a window operation restriction notification unit 105 by loading and executing a second control program 111 saved in the second memory 110.


The second processor 100 corresponds to the computer of the present disclosure, and the second control program 111 corresponds to the mobile body control program of the present disclosure. The second control program 111 may be recorded on a recording medium such as a magnetic disk, an optical disc, or a flash memory, loaded on the second control device 90 from the recording medium, and saved in the second memory 110, or may also be downloaded to the second control device 90 from an external system such as the mobile body support server 510 and saved in the second memory 110.


The processing executed by the window open or close instruction recognition unit 102 corresponds to a window open or close instruction recognition step of the mobile body control method according to the present disclosure, and the processing executed by the window operation restriction unit 104 corresponds to a window operation restriction step of the mobile body control method according to the present disclosure.


The voice recognition unit 101 analyzes the voice detected by the microphone 30 and recognizes the instruction content made by the voice of the passengers. In the embodiment, the voice recognition unit 101 starts to recognize the instruction by the voice upon recognizing a prescribed wakeup word (“Ok, my car”, or the like) or when the talk switch 33 is operated. The window open or close instruction recognition unit 102 recognizes that the voice instruction recognized by the voice recognition unit 101 is instructing to open or close a window.


The window lock information saving unit 103 saves, in the second memory 110, window lock information 112 indicating as being in a window lock state or a window unlock state by an operation of the window lock switch 12a through executing the processing of the flowchart illustrated in FIG. 5.


In step S1 of FIG. 5, the window lock information saving unit 103 recognizes the operation state of the window lock switch 12a recognized by the switch operation state recognition unit 71 by having communication between the first control device 60 and the second control device 90. In following step S2, the window lock information saving unit 103 determines whether the window lock switch 12a is in a lock instructed state.


Then, the window lock information saving unit 103 shifts the processing to step S4 when the window lock switch 12a is in a lock instructed stated, and shifts the processing to step S3 when the window lock switch 12a is in an unlock instructed state. In step S4, the window lock information saving unit 103 saves the window lock information 112 indicating as being in a window lock state to the second memory 110. In step S3, the window lock information saving unit 103 saves the window lock information 112 indicating as being in a window unlock state to the second memory 110.


Thereby, when checking whether it is in a window lock state by the second control device 90, it becomes possible to promptly recognize whether it is in a window lock state by referring to the window lock information 112 without performing communication between the first control device 60 and the second control device 90 each time to check the operation state of the window lock switch 12a.


The window operation restriction unit 104 executes the processing (window operation inhibition processing) for restricting the operation of the window by the voice of the passengers as in following (2-1) to (2-2) according to the conditions indicated in FIG. 4.


(2-1. In a Case where Voice Recognition is Activated by Wakeup Word)


When it is in a window unlock state, the passengers on all seats are capable of performing open or close operations of the driver seat window 11, the front seat window 16, the right rear seat window 21, the left rear seat window 26, the sunroof 40, and the sunshade 41.


When it is in a window lock state, the passengers on all seats are capable of performing only the open or close operation of the sunshade 41 but not capable of performing the open or close operations of the driver seat window 11, the front seat window 16, the right rear seat window 21, the left rear seat window 26, and the sunroof 40. Thereby, in accordance with the kinds of the windows, it is possible to give an instruction to open or close the sunshade 41 that is relatively lightweight by a voice operation even in a window lock state, while it is not possible to perform the open or close operations by the voice operation for the driver seat window 11, the front seat window 16, the right rear seat window 21, the left rear seat window 26, and the sunroof 40 other than sunshade 41.


(2-2. In a Case where Voice Recognition is Activated by Talk Switch 33)


When it is in a window unlock state, the driver is capable of performing open or close operations of the driver seat window 11, the front seat window 16, the right rear seat window 21, the left rear seat window 26, the sunroof 40, and the sunshade 41.


When it is in a window lock state, the driver is capable of performing only the open or close operation of the sunshade 41 but not capable of performing the open or close operations of the driver seat window 11, the front seat window 16, the right rear seat window 21, the left rear seat window 26, and the sunroof 40.


In a case where the operation by the voice is restricted by the window operation restriction unit 104 because of the window lock state, the window operation restriction notification unit 105 displays, on the touch panel 32, a screen notifying that the operation by the voice is being inhibited when the voice recognition unit 101 recognizes an open or close instruction by the voice for any of the driver seat window 11, the front seat window 16, the right rear seat window 21, the left rear seat window 26, and the sunroof 40.


3. Window Open or Close Processing According to Voice Instruction

Window open or close processing performed in accordance with a voice instruction will be described according to flowcharts illustrated in FIG. 6 to FIG. 7.


When a wakeup word is recognized in S10 or the talk switch 33 is operated in S20 by looping through steps S10 and S20 of FIG. 6, the voice recognition unit 101 shifts the processing to step S11. When a voice instruction is recognized in step S11 before a prescribed time passes in step S30 by looping through steps S11 and S30, the voice recognition unit 101 shifts the processing to step S12. Furthermore, when a prescribed time has passed in step S30, the voice recognition unit 101 shifts the processing to step S10.


In step S12, the window open or close instruction recognition unit 102 determines whether the voice instruction is an open or close instruction of the window. Then, the window open or close instruction recognition unit 102 shifts the processing to step S13 when the voice instruction is an open or close instruction of the window, and shifts the processing to step S10 when the voice instruction is not an open or close instruction of the window.


In step S13, the window open or close instruction recognition unit 102 determines whether the target of the open or close instruction is the sunshade 41. Then, the window open or close instruction recognition unit 102 shifts the processing to step S15 of FIG. 7 when the target of the open or close instruction is the sunshade 41, and shifts the processing to step S14 of FIG. 7 when the target of the open or close instruction is not the sunshade 41.


In step S14, the window operation restriction unit 104 refers to the window lock information saved in the second memory 110 and recognizes whether it is in a window lock state. Then, when it is in a window lock state, the window operation restriction unit 104 shifts the processing to step S50 where a screen 200 notifying that it is in a window lock state and that the operation of the windows by the voice is not possible is displayed on the touch panel 32, and then shifts the processing to step S10.


In the meantime, when it is not a window lock state (in a window unlock state), the window operation restriction unit 104 shifts the processing to step S15 of FIG. 7. In this case, operations of the windows by the voice are not restricted. In step S15, the window control unit 72 executes an open operation or a close operation of the window in accordance with a voice instruction.


The window control unit 72 recognizes the window of the operation target and the operation direction (open operation or close operation) based on an execution command corresponding to the voice instruction transmitted to the first control device 60 from the second control device 90. For example, when the voice instruction is “open the window of the front seat”, the window control unit 72 operates the actuator 16a of the front seat window 16 to the opening direction so as to open the front seat window 16.


In following step S16, the window operation restriction notification unit 105 displays, on the touch panel 32, a window-operating screen 210 notifying that the window is being operated. On the window operating screen 210, a window stop button 211 for instructing to stop the operating window is displayed. The window stop button 211 corresponds to a switch provided to the mobile body of the present disclosure.


Following step S17 and steps S60 to S61 are the processing (window operation stop processing) performed by the window operation restriction unit 104. By looping through step S17 and step S60, the window operation restriction unit 104 determines in step S17 whether the operation of the window is ended, and determines in step S60 whether the window stop button 211 is operated.


Then, when the operation of the window is ended, the window operation restriction unit 104 shifts the processing from step S17 to step S18. Furthermore, when the window stop button 211 is operated, the window operation restriction unit 104 shifts the processing from step S60 to step S61 to stop the operating window, and then shifts the processing to step S18.


Note that the operating window may also be stopped in accordance with the voice instruction, when a switch other than the window stop button provided to the vehicle 1 is operated. For example, the window operation restriction unit 104 may stop the operating window, when any of the driver seat window switch 12b, the front seat window switch 12c, the right rear seat window switch 12d, and the left rear seat window switch 12e of the driver seat door switch 12, the front seat door switch 17, the right rear seat door switch 22, and the left rear seat door switch 27 is operated.


4. Another Embodiment

In the embodiment above, described is the processing of a case where the window open or close instruction recognition unit 102 recognizes the voice operation giving an open or close instruction of the window. As another embodiment, the window open or close instruction recognition unit 102 executes the same processing as that of the case where the voice operation is recognized, also when the buttons 301 to 306 for operating respective windows displayed on the touch panel of the mobile terminal 300 are operated, as described above by referring to FIG. 1.


That is, the window open or close instruction recognition unit 102 executes the processing where the voice operation in the flowcharts of FIG. 6 to FIG. 7 is replaced with the operations of the buttons 301 to 306 displayed on the touch panel of the mobile terminal 300. Specifically, the processing of steps S10, S11, S12, S20, and S30 in FIG. 6 is “processing of determining which of the buttons 301 to 306 is operated”, and step S50 is the processing of “notifying that the open or close operation of the window via the mobile terminal is inhibited”.
