Detailed Description

Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. The following embodiments are not limited to the invention according to the technical means, and all combinations of the features described in the embodiments are not limited to the combinations essential to the invention. Two or more of the features described in the embodiments may be arbitrarily combined. The same or similar structures are denoted by the same reference numerals, and repetitive description thereof will be omitted.

With reference to fig. 1, an external appearance of a vehicle 100 according to some embodiments will be described. The vehicle 100 is a saddle-riding motorcycle. Instead, the present invention can also be applied to other vehicles such as a four-wheel vehicle or a three-wheel vehicle. Fig. 1 is a front rear view of a vehicle 100.

The vehicle 100 has a display device 101 at the center in the vehicle width direction. The display device 101 displays information of a driver (hereinafter, simply referred to as a driver) facing the vehicle 100. The display device 101 may be a dot matrix type display device such as a liquid crystal display or an organic EL (electroluminescence) display, or may be a set of indicators that are notified by turning off or on (or blinking) a predetermined mark.

The vehicle 100 includes a left handlebar switch 102 on the inner side of the left handlebar in the vehicle width direction. The appearance of the left side handlebar switch 102 will be described with reference to fig. 2. The left handlebar switch 102 includes a plurality of switches. At least some of the plurality of switches are operable by a left-hand thumb while the driver holds the left-hand handlebar with the left hand. A switch used for a cooperative function (described below) of the vehicle 100 and the mobile device will be described below. The other switches of the left-side handle switch 102 (i.e., the switches used for the functions of the vehicle 100 other than the cooperative function) may have the same configuration as the conventional ones, and thus their description is omitted.

The left handlebar switch 102 includes an upper switch 200U, a lower switch 200D and a left-right switch 200H. The left-right switch 200H is disposed substantially in the center of the left handlebar switch 102. The left-right switch 200H is a tilt switch capable of tilting in the left-right direction. The driver can input a left direction instruction by tilting the left-right switch 200H to the left, and can input a right direction instruction by tilting the left-right switch 200H to the right. The upper switch 200U is disposed above the left and right switches 200H. The upper switch 200U is a push-type switch. The driver can input an upward direction instruction by pressing the up switch 200U. The lower switch 200D is disposed below the left and right switches 200H. The lower switch 200D is a push-type switch. The driver can input a downward direction instruction by pressing the down switch 200D. The upper switch 200U, the lower switch 200D, and the left-right switch 200H are collectively referred to as a direction switch 200. The direction switch 200 is not limited to the configuration of fig. 2, and may have any configuration capable of inputting instructions of four directions.

With reference to fig. 3, a functional configuration of a collaboration system 350 that provides collaboration functions according to some embodiments of the present invention will be described. The collaboration system 350 includes the vehicle 100, the mobile device 310, the portable communication device 320 (headset), and the electronic key 340 described above. Here, the portable communication device 320 is configured to be capable of being mounted inside the helmet 330 of the driver. The portable communication device 320 is configured to be detachable from and portable with the helmet 330.

(Structure of vehicle 100)

The vehicle 100 includes a control unit 301, a display unit 304, a direction input unit 305, a communication unit 306, an output unit 307, and a driving device 308. The control unit 301 controls the entire vehicle 100. The control unit 301 is composed of, for example, a processor 302 and a memory 303. In this case, the operation by the control unit 301 is realized by the processor 302 executing a program stored in the memory 303. Part or all of the operations of the control unit 301 may be realized by a dedicated circuit such as an ASIC (application specific integrated circuit) or an FPGA (field programmable gate array).

The display portion 304 displays information for the driver. The display unit 304 is realized by the display device 101, for example. The direction input section 305 acquires instructions from four directions of the driver. The direction input unit 305 is implemented by, for example, the upper switch 200U, the lower switch 200D, and the left-right switch 200H. The communication portion 306 provides a function for the vehicle 100 to communicate with the outside. The communication unit 306 may support short-range wireless communication such as Bluetooth (registered trademark). The communication unit 306 may support cellular communication, road-to-vehicle communication, and the like.

The direction input unit 305 may receive two-stage input for each direction using the direction switch 200. For example, the direction input unit 305 may accept a short-press input (for example, an input having a duration of less than 1 second) and a long-press input (for example, an input having a duration of 1 second or more). Alternatively, the direction input unit 305 may accept a single click input (for example, an input in which an interval of 1 second or more is present until the subsequent input) and a double click input (for example, two consecutive inputs in which an interval of less than 1 second is present).

The output unit 307 includes a speaker therein, and gives an alarm under the control of the control unit 301. The driving device 308 is a device that generates driving force for running the vehicle 100, and may be configured by an engine, a motor, a battery, a transmission, and the like. The output of the driving device 308 is controlled by the control unit 301.

The control unit 301 can measure the distance and direction between the communication unit 306 of the vehicle 100 and the communication unit 323 of the portable communication device 320 (headphone) by the radio wave intensity in the wireless communication between the communication unit 306 and the communication unit 323 of the portable communication device 320 (headphone) registered in the communication unit 306 by the pairing of the short-range wireless communication. After the vehicle 100 is stopped, the control unit 301 sets a guard mode for preventing the portable communication device 320 (headphone) from being stolen.

Fig. 18 is a timing chart of the processing in the control section 301. The control unit 301 sets a guard mode and starts processing based on the reception of a signal (ign_off signal) for turning OFF the ignition switch.

In this precaution mode, the control unit 301 determines whether or not the portable communication device 320 (headphone) is present within a predetermined distance DS as shown in fig. 19, for example, based on a determination using measurement of radio wave intensity in wireless communication, and when it is determined that the portable communication device 320 is not present within the predetermined distance, controls the output unit 307 of the vehicle 100 to sound an alarm (process 1802 in fig. 18). As an example of a determination process in the case of sounding an alarm, after a predetermined time has elapsed, the control unit 301 can control whether or not to sound an alarm based on a state change in the presence state of the portable communication device 320 within a predetermined distance. For example, the control unit 301 may control the output unit 307 to sound an alarm when it is determined that the communication unit 323 of the portable communication device 320 is within a predetermined distance after a predetermined time elapses from the stop of the vehicle 100 and the communication unit 323 of the portable communication device 320 is in a state of being not within the predetermined distance.

On the other hand, in order to prevent erroneous determination in the determination process, the control unit 301 can perform a determination process for distinguishing between a case where the driver leaves the vehicle 100 with the portable communication device 320 (headset) mounted in the helmet 330 and a case where a third person other than the driver steals the helmet 330 (portable communication device 320 (headset)) held in the vehicle 100 and leaves the vehicle 100. The judgment processing for preventing erroneous judgment corresponds to the processing 1801 and the processing 1803 shown in fig. 18, and when the driver leaves a predetermined distance from the vehicle 100 with the portable communication device 320 mounted in the helmet 330, the prevention mode is terminated without sounding an alarm.

As shown in fig. 18, it is assumed that after the vehicle 100 is stopped and the guard mode is set, for example, before a predetermined time elapses, the driver carries the helmet 330 (portable communication device 320 (headphone)) and leaves the vehicle 100. In such a case, the control unit 301 does not generate an alarm in order to prevent erroneous determination. That is, when the control unit 301 determines that the communication unit 323 of the portable communication device 320 is not present within the predetermined distance DS (fig. 19) before the predetermined time elapses from the stop of the vehicle 100 (after the prevention mode is set), the alarm is not sounded from the output unit 307 (processing 1801 of fig. 18).

In order to suppress the power consumption of the battery caused by the short-range wireless communication in the guard mode, the control unit 301 ends the guard mode when it is determined that the communication unit 323 of the portable communication device 320 is not present within a predetermined distance before a predetermined time elapses from the stop of the vehicle 100 (after the guard mode is set).

The control unit 301 measures the distance and direction from the electronic key 340 described later, and when the distance and direction from the electronic key 340 and the distance (change in distance) and direction (change in direction) from the helmet 330 are substantially the same, the control unit 301 does not generate an alarm (process 1803 in fig. 18). In this case, the control unit 301 does not generate an alarm and ends the precautionary mode, in a state in which the driver leaves the vehicle 100 while carrying the helmet 330 and the electronic key 340. The specific processing by the control unit 301 will be described in the third embodiment with reference to fig. 17 to 22.

(Structure of Mobile device 310)

The mobile device 310 includes a control unit 311, a display unit 314, an input unit 315, a communication unit 316, and an output unit 317. The mobile device 310 may be a mobile phone device such as a smart phone, for example. The user of the mobile device 310 may be the same as the driver. Hereinafter, a case where the driver uses the mobile device 310 will be described. The mobile device 310 may be held by the driver or may be housed in the vehicle 100. The control unit 311 controls the entire mobile device 310. The control unit 311 is composed of, for example, a processor 312 and a memory 313. In this case, the operation by the control unit 311 is realized by the processor 312 executing a program stored in the memory 313. Programs may also include an operating system and applications. Part or all of the operations of the control unit 311 may be realized by a dedicated circuit such as an ASIC or FPGA.

The display 314 displays information for the driver. The display unit 314 is implemented by a display device such as a liquid crystal display or an organic EL display, for example. The input section 315 acquires an input from the driver. The input unit 315 is implemented by an input device such as a touch panel or buttons, for example. The communication section 316 provides a function for the mobile device 310 to communicate with the outside. The communication unit 316 may support short-range wireless communication such as Bluetooth (registered trademark). The communication unit 306 may support cellular communication, wiFi (registered trademark) communication, and the like.

The communication unit 316 of the mobile device 310 can communicate with the communication unit 306 of the vehicle 100. In the precaution mode, when it is determined that the communication unit of the portable communication device is not present within the predetermined distance, the control unit 301 of the vehicle 100 outputs notification information indicating the result of the determination to the mobile device 310 registered in the communication unit 306 of the vehicle 100.

When receiving the notification information from the vehicle 100, the control unit 311 of the mobile device 310 displays the result of the determination on the display unit 314.

The output unit 317 includes a speaker therein, and when receiving notification information indicating the result of the determination from the vehicle 100, the control unit 311 of the mobile device 310 notifies the result of the determination by sounding from the output unit 317.

(Structure of Portable communication device 320 (Headset))

The portable communication device 320 (headphone) is configured to be attachable to the inside of the helmet 330 of the driver, and includes a microphone 321, a speaker 322, and a communication unit 323. The portable communication device 320 is fitted to the head of the driver. The microphone 321 acquires a voice input from the driver. Speaker 322 outputs a voice for the driver. The communication unit 323 may support short-range wireless communication such as Bluetooth (registered trademark). The communication unit 323 can communicate with the communication unit 306 of the vehicle 100 by wireless communication.

(Structure of electronic Key 340)

The electronic key 340 has a communication unit 341 and a storage unit 342. The communication unit 341 may support short-range wireless communication such as Bluetooth (registered trademark). The communication unit 341 can communicate with the communication unit 306 of the vehicle 100 by wireless communication. The storage unit 342 stores authentication information of the electronic key 340, and the electronic key 340 can be carried by the driver of the vehicle 100.

To start the driving device 308 of the vehicle 100, first, wireless communication is performed between the communication unit 341 of the electronic key 340 and the communication unit 306 of the vehicle 100, and when the authentication information of the electronic key 340 stored in the storage unit 342 matches the authentication information registered in advance in the memory 303 (storage unit) of the vehicle 100, the control unit 301 releases the lock of the driving device 308 and turns on the ignition switch, whereby the driving device 308 of the vehicle 100 is started.

The authentication by the electronic key 340 can also be performed by the mobile device 310. For example, the authentication information may be stored in the memory 313 of the mobile device 310, and transmitted from the mobile device 310 to the communication unit 316 of the vehicle 100 by wireless communication. The control unit 311 of the vehicle 100 determines whether or not the authentication information registered in advance in the memory 303 (storage unit) matches the authentication information, and if the authentication information matches the authentication information, the authentication is established, and if the authentication information does not match the authentication information, the authentication is not established. When authentication is established between the mobile device 310 and the vehicle 100, the control unit 301 of the vehicle 100 may start the driving device 308 of the vehicle 100 by unlocking the driving device 308 and turning on the ignition switch.

The control unit 301 of the vehicle 100 can measure the distance and direction between the communication unit 306 of the vehicle 100 and the communication unit 341 of the electronic key 340 by the radio wave intensity in the wireless communication between the communication unit 306 and the communication unit 341 of the electronic key 340 registered in the communication unit 306 by the pairing of the short-range wireless communication.

In some embodiments of the present invention, the vehicle 100 and the mobile device 310 cooperate with each other. Specifically, a communication link based on short-range wireless communication is established between the vehicle 100 and the mobile device 310, for example. The vehicle 100 and the mobile device 310 exchange data via the communication link. In addition, a communication link based on short-range wireless communication is established between the mobile device 310 and the portable communication device 320, for example. The mobile device 310 and the portable communication device 320 exchange data via the communication link.

At least a portion of the plurality of functions provided by mobile device 310 are capable of cooperating with vehicle 100. The function that can cooperate with the vehicle 100 among the functions provided by the mobile device 310 is hereinafter referred to as a cooperation function. The driver inputs a direction to the mobile device 310 through the direction input unit 305 of the vehicle 100. The directional input is sent from the vehicle 100 to the mobile device 310. The mobile device 310 performs an operation of the cooperative function according to a direction input from the driver, and generates an image representing an operation state. The mobile device 310 transmits the generated image to the vehicle 100. The vehicle 100 displays the received image on the display unit 304.

In addition, the mobile device 310 transmits a voice output to the driver to the portable communication device 320. Portable communication device 320 outputs the received voice output from speaker 322. The portable communication device 320 transmits the voice input from the driver, acquired by the microphone 321, to the mobile device 310. The mobile device 310 performs an action of a cooperative function corresponding to a voice input from the driver.

(first embodiment)

A first embodiment of a case where the display device 101 is a dot matrix will be described. Fig. 4 illustrates a display example of display unit 304 during the cooperative operation of vehicle 100 and mobile device 310. The screen 400 is an example of a screen displayed on the display device 101. The travel speed is displayed in the center of the screen 400, and the fuel level is displayed below the travel speed. A tachometer is displayed on the left side of the screen 400.

The area 401 located on the right side of the screen 400 is an area for displaying an image provided from the mobile device 310 by the vehicle 100 in cooperation with the mobile device 310. Hereinafter, such an image is referred to as a cooperative image. During periods when no collaboration images are provided from mobile device 310 (i.e., during periods when vehicle 100 is not collaborating with mobile device 310), vehicle 100 may also display other images, such as images not associated with collaboration functions, in region 401. For example, the vehicle 100 may display selectable images such as a riding mode parameter (for example, information set in the vehicle 100 such as an operating condition of an ABS (antilock brake system)) and a level adjustment in the region 401. In the region 401, an image of low importance among images not associated with the cooperative function (for example, images related to the running of the vehicle 100) may be displayed. By sharing the image of low importance with the collaborative image without associating the region 401 with the collaborative function, the space of the screen 400 can be effectively utilized.

The area 402 located on the lower side of the screen 400 is an area for displaying an image provided from the mobile device 310 in a state in which the vehicle 100 is not in cooperation with the mobile device 310. Hereinafter, such an image is referred to as an interruption image. During periods when no interrupt image is provided from mobile device 310, vehicle 100 may also display other images, such as images not associated with a collaboration function, in area 402.

A specific operation example of the cooperation function will be described with reference to fig. 5 to 9. The mobile device 310 provides a number of collaboration functions. The plurality of collaboration functions may include two or more of a weather information providing function, a call function, a messaging function, a music playing function, and a route guidance function. Hereinafter, a case where the mobile device 310 provides all of the five cooperative functions will be described. The weather information providing function refers to a function of providing information of the weather of a specific place. The climate may include at least one of weather and air temperature. The call function is a function of making a call with another person. The messaging function refers to a function of exchanging text/messages with others. The music playing function refers to a function of playing music. The route guidance function is a function of guiding a route to a specified destination.

The mobile device 310 receives two types of inputs from the vehicle 100 for four directions (up, down, left, right), respectively. In the following example, the case where two types of inputs are short press and long press is handled. In FIGS. 5 to 9, the short press is indicated by a darkened triangle, and the long press is indicated by a darkened triangle labeled "]. In fig. 5 to 9, all the images other than the image 500 are collaborative images, that is, images that the mobile device 310 transmits to the vehicle 100 and displays on the display device 101 of the vehicle 100 in the course of executing the collaborative function. Therefore, in the following description of fig. 5 to 9, description of display of the subsequent cooperative image is omitted until transmission of the cooperative image is described.

While the vehicle 100 is not cooperating with the mobile device 310 (i.e., while the mobile device 310 is not executing any cooperation function), an image 500 other than the cooperation function is displayed in the area 401 of the screen 400. When a long left press input is acquired from the driver via the direction input unit 305 of the vehicle 100 while the mobile device 310 is not in cooperation with the vehicle 100, the mobile device starts cooperation with the vehicle 100. In the following description, the direction input is also acquired from the driver via the direction input unit 305 of the vehicle 100, and therefore, only the input direction (up, down, left, right) and the input method (short press/long press) will be described below.

The plurality of collaboration functions have top page images, respectively. The top page image is an image that the mobile device 310 transmits to the vehicle 100 for one of the cooperation functions immediately after the cooperation function is selected. The image 501 is a top page image of the weather information providing function. An image 501 shows the current weather of the vehicle 100 and the current air temperature. When a destination is set in the vehicle 100, an image indicating the weather of the destination and the air temperature of the destination may be displayed on the image 501. Image 502 is a top page image of the call function. The image 502 contains an image representing a call function. The image 503 is a top page image of the path guidance function. The image 503 contains an image representing a path guidance function. Image 504 is a top page image of the music playing function. The image 504 contains an image representing a music play function. Image 505 is a top page image of a messaging function. Image 505 contains an image representing a messaging function.

When the collaboration is started, the mobile device 310 selects any one of the plurality of collaboration functions, and transmits a top page image of the selected collaboration function. The cooperation function selected here may be a cooperation function set in advance as an initial function. Such a cooperative function is referred to as an initial cooperative function. In the following description, a call function is set as an initial collaboration function. Thus, the mobile device 310 transmits the image 502 immediately after the collaboration begins. The driver can set the other cooperative function as the initial cooperative function. The mobile device 310 may also notify that collaboration has been initiated by voice.

When the mobile device 310 acquires the right long press input in a state in which the top page image (in this example, the image 502) of the initial cooperation function is displayed, the cooperation with the vehicle 100 is ended. In this case, the mobile device 310 transmits a notification to the vehicle 100 to end the cooperation, and the vehicle 100 ends the cooperation operation based on the notification and displays the image 500 other than the cooperation function in the area 401. The mobile device 310 may also notify the end of the collaboration by voice.

As described above, the collaborative image is displayed in the region 401 located on the right side of the screen 400. Therefore, when the cooperative image is displayed in the region 401 at the start of the cooperation, the driver feels that the cooperative image passes beyond the right end of the screen 400 from the outside of the screen 400 and enters the region 401. Since the input direction (left direction) for starting the cooperative motion coincides with the assumed moving direction of the cooperative image, the driver can intuitively start the cooperative function. In order to make this effect more remarkable, the vehicle 100 may be displayed in an animation such as a collaborative image from the right side in the region 401. When the cooperative image in the region 401 is deleted at the end of the cooperation, the driver feels that the cooperative image is moved beyond the right end of the screen 400 and is moved outside the screen 400. Since the input direction (right direction) for ending the cooperative motion coincides with the assumed moving direction of the cooperative image, the driver can intuitively end the cooperative function. In order to make this effect more remarkable, the vehicle 100 may be displayed in an animation in which the cooperative image is deviated from the region 401 to the right. Further, the vehicle 100 may also correspond to the input direction to the movement direction of the image in the display of another cooperative image. That is, the vehicle 100 may display an image received as a response to the instruction to transmit the upward, downward, leftward, and downward directions to the mobile device 310 by moving in the instructed direction.

Next, a description will be given of switching a plurality of cooperation functions. When the mobile device 310 acquires the up short press input or the down short press input in a state where any one of the top page images (any one of the images 501 to 505) of the plurality of collaboration functions is displayed, the mobile device switches the collaboration function in the selection to another collaboration function, and transmits the top page image of the collaboration function after the switching. For example, when the mobile device 310 acquires the press-down input in a state where the top page image of the selected collaboration function is displayed, the collaboration function in the selection is switched in the order of the weather information providing function, the call function, the route guidance function, the music playing function, and the messaging function, and the top page image (any one of the images 501 to 505) corresponding to the switched collaboration function is transmitted. Further, the mobile device 310 switches the selected collaboration function in reverse order in response to the acquisition of the short press input in a state in which the top page image of the selected collaboration function is displayed, and transmits the top page image (any one of the images 501 to 505) corresponding to the switched collaboration function. Although not shown, a direct switch from the weather information providing function to the messaging function and a reverse switch may be possible. The mobile device 310 may also notify the switched collaboration function by voice at the same time as the switching of the collaboration function.

Even when a long left press input is acquired during the display of any of the collaboration images shown in fig. 5 to 9, the mobile device 310 can shift to the transmission of the top page image (image 502 in this example) of the initial collaboration function. When a long press input is acquired during the display of any of the collaborative images shown in fig. 5 to 9, the mobile device 310 sets the volume of the voice output to the driver to zero (i.e., suppresses noise). On the other hand, when the mobile device 310 receives the long press input in the sound deadening state, the sound deadening state is released and the sound volume before sound deadening is restored. The mobile device 310 may end the cooperation operation when the right long press input is acquired while any of the cooperation images shown in fig. 5 to 9 is displayed. Alternatively, the mobile device 310 may receive the instruction to end the cooperative operation only in a state where the top page image of the initial cooperative function (in this example, the image 502) is displayed, or may receive the instruction to end the cooperative operation only in a state where the top page image of any one of the cooperative functions is displayed.

A specific operation example of the call function will be described with reference to fig. 6. When the right short press input is acquired while the image 502 is displayed, the mobile device 310 shifts to transmission of the image 602. The image 602 is an image for requesting a designation of a call target from the driver. The mobile device 310 may request the designation of the call target from the driver by voice while transmitting the image 602. When the mobile device 310 acquires the down-press input, the right-press input, and the left-press input while the image 602 is displayed, it shifts to transmission of the image 603, transmission of the image 604, and transmission of the image 502, respectively.

The image 603 is an image including a name of a call target set in advance. When transferring to the transmission of the image 603, the mobile device 310 reads out a name set in advance as a call target from the memory 313 and includes the name in the image 603. The mobile device 310 may transmit the image 603 and simultaneously notify the driver of the read name of the call target by voice. When the up short press input, the right short press input, and the left short press input are acquired while the image 603 is displayed, the mobile device 310 shifts to transmission of the image 602, transmission of the image 606, and transmission of the image 502, respectively.

The image 604 is an image showing a standby state of voice search. The image 604 may also contain an image representing the input direction for ending the voice search. The mobile device 310 may also notify the driver of the waiting for voice search by voice while transmitting the image 603. After transmitting the image 604, the mobile device 310 waits for voice input via the portable communication device 320. After obtaining the voice input, mobile device 310 searches for a call object from the contact list in memory 313 based on the voice input. The mobile device 310 shifts to transmission of the image 605 when the call target can be determined, and does not transmit a new image when the call target cannot be determined (i.e., the vehicle 100 continues display of the image 604). If the call target cannot be specified, the mobile device 310 may notify the driver of the call target by voice. When the left short press input is acquired while the image 604 is displayed, the mobile device 310 shifts to transmission of the image 602.

The image 605 is an image containing the name of the call object determined by the voice search. The mobile device 310 may also notify the driver of the determined name of the call object by voice while transmitting the image 605. When the right short press input and the left short press input are acquired while the image 605 is displayed, the mobile device 310 shifts to transmission of the image 606 and transmission of the image 602, respectively.

The image 606 is an image showing the execution status of the call function. The image 606 may also contain the call object and the call status (in-call or in-call (in this case, talk time)). The image 606 may also contain an image representing the direction of the input for ending the call. The mobile device 310 starts the power-off to the call target while transmitting the image 606, and updates the image 606 according to the call situation. Voice of a call is input and output between the mobile device 310 and the driver via the portable communication device 320. When the mobile device 310 acquires the left short press input while the image 606 is displayed, the call is ended, and the transmission of the image 502 is shifted. In the case where the mobile device 310 acquires the up-short press input or the down-short press input in the state where the image 606 is displayed, the volume output from the portable communication device 320 is increased or decreased. When the left long press input is acquired while the image 606 is displayed, the mobile device 310 transitions to transmission of the image 601 while continuing the call.

Image 601 is a top page image of a call function that is executing the call function. On the other hand, the image 502 is a top page image in which a call function other than the call function is being executed. The call function being performed may also be that a call or a call with a call partner is being made. The image 601 may include a call target and a call status (call in progress, call in progress (call time in this case)). Since the image 601 is a top page image, when the mobile device 310 acquires the up short press input or the down short press input while the image 601 is displayed, the call function is switched to another collaboration function. The mobile device 310 may maintain the call state when the call function is switched to another collaboration function during the time when the call function is being executed. When the right short press input is acquired while the image 601 is displayed, the mobile device 310 transitions to transmission of the image 606 while continuing the call. When the call is ended (call target end call) with the image 601 displayed, the mobile device 310 shifts to transmission of the image 502. The mobile device 310 may not receive an instruction to end the call from the driver in a state where the image 601 is displayed.

A specific operation example of the path guidance function will be described with reference to fig. 7. When the mobile device 310 acquires the right short press input in the state where the image 503 is displayed, the transmission of the image 702 is shifted. The image 702 is an image for requesting designation of a destination from a driver. The mobile device 310 may also request designation of a destination from the driver by voice while transmitting the image 702. When the mobile device 310 acquires the down-press input, the right-press input, and the left-press input while the image 702 is displayed, it shifts to transmission of the image 703, transmission of the image 704, and transmission of the image 503, respectively.

The image 703 is an image including a destination set in advance. When transferring transmission to the image 703, the mobile device 310 reads a location set in advance as a destination from the memory 313 and includes the location in the image 703. The mobile device 310 may also notify the driver of the read destination by voice while transmitting the image 703. When the up short press input, the right short press input, and the left short press input are acquired while the image 703 is displayed, the mobile device 310 shifts to transmission of the image 702, transmission of the image 706, and transmission of the image 503, respectively.

The image 704 is an image showing a standby state of voice search. The image 704 may also contain an image representing the input direction for ending the voice search. The mobile device 310 may also notify the driver of the waiting for voice search by voice while transmitting the image 703. After transmitting the image 704, the mobile device 310 waits for voice input via the portable communication device 320. After acquiring the voice input, the mobile device 310 determines a destination based on the voice input, for example, from map information. The mobile device 310 shifts to transmission of the image 705 if the destination can be determined, and does not transmit a new image if the destination cannot be determined (i.e., the vehicle 100 continues display of the image 704). The mobile device 310 may also notify the driver of the fact by voice in the case where the destination cannot be determined. When the left short press input is acquired while the image 704 is displayed, the mobile device 310 shifts to transmission of the image 702.

The image 705 is an image containing a destination determined by voice search. The mobile device 310 may also notify the driver of the determined destination by voice while transmitting the image 705. When the right short press input and the left short press input are acquired while the image 705 is displayed, the mobile device 310 shifts to transmission of the image 706 and transmission of the image 702, respectively.

The image 706 is an image showing the execution status of the route guidance function. The image 706 may include a distance to a place where the vehicle should turn and a turning direction. The image 706 may also contain an image representing the input direction for ending the path guidance. The mobile device 310 starts path guidance while transmitting the image 706, and updates the image 706 according to the guidance status. The path-guided voice is output from the mobile device 310 to the driver via the portable communication device 320. When the left short press input is acquired while the image 706 is displayed, the mobile device 310 shifts to transmission of the image 707. In the case where the mobile device 310 acquires the up-short press input or the down-short press input in the state where the image 706 is displayed, the volume output from the portable communication device 320 is increased or decreased.

The image 707 is an image for confirming whether or not to end the route guidance. The image 707 may include an image requesting confirmation and an image representing an input direction for responding to the confirmation. When the mobile device 310 acquires the right short press input while the image 707 is displayed, the path guidance is ended and the transmission of the image 503 is shifted. When the right long press input is acquired while the image 707 is displayed, the mobile device 310 transitions to transmission of the image 706 while continuing the path guidance.

The image 701 is a top page image of the path guidance function in the path guidance functions being executed. On the other hand, the image 503 is a top page image in which a route guidance function other than the route guidance function is being executed. The route guidance function being executed may be a condition in which the route is being guided toward the driver. The image 701 may include the distance to the place where the vehicle should turn and the turning direction. As described above, when the mobile device 310 acquires the long left press input in a state where the route guidance function (that is, any one of the image 503 and the images 701 to 707 is displayed) is selected, the mobile device transitions to the transmission of the top page image of the initial cooperation function. In the case where the route guidance function is selected again later, if route guidance is being performed at the time of the last selection, the mobile device 310 transmits the image 701 as a top page image of the route guidance function.

Since the image 701 is a top page image, when the mobile device 310 acquires the up short press input or the down short press input in the state where the image 701 is displayed, the path guidance function is switched to another cooperation function. When the right short press input is acquired while the image 701 is displayed, the mobile device 310 transitions to transmission of the image 706 while continuing the route guidance. When the mobile device 310 ends the route guidance (reaches the destination) in the state where the image 701 is displayed, it shifts to transmission of the image 503. The mobile device 310 may not receive an instruction to end the route guidance in a state where the image 701 is displayed.

A specific operation example of the music playing function will be described with reference to fig. 8. When the right short press input is acquired while the image 504 is displayed, the mobile device 310 shifts to transmission of the image 802. Image 802 is an image for searching for music to be played. The mobile device 310 selects a song in the playlist in memory 313 while transmitting the image 802 and is included in the image 802. The mobile device 310 may also notify the driver of the name of the selected song by voice while transmitting the image 802. When the right short press input and the left short press input are acquired while the image 802 is displayed, the mobile device 310 shifts to transmission of the image 803 and transmission of the image 504, respectively. In the case where the mobile device 310 acquires the short press input in the state where the image 802 is displayed, the last song in the playlist is selected, and the image 802 is updated accordingly. In the case where the mobile device 310 acquires the press-down input in the state where the image 802 is displayed, the next song in the playlist is selected, and the image 802 is updated accordingly.

The image 803 is an image showing the execution status of the music play function. The image 803 may also contain the name of the song being played and the playing status (playing time). The image 803 may contain an image representing the input direction for ending the play and the input direction for skipping the song being played. The mobile device 310 updates the image 803 according to the play status of the song while transmitting the image 803. The song being played is output from the mobile device 310 to the driver via the portable communication device 320. When the left short press input is acquired while the image 803 is displayed, the mobile device 310 ends the playback and shifts to transmission of the image 802. When the mobile device 310 acquires the right short press input in the state in which the image 803 is displayed, the next song in the playlist is selected, and the image 803 is updated accordingly. When the up short press input or the down short press input is acquired in a state where the image 803 is displayed, the mobile device 310 increases or decreases the volume output from the portable communication device 320. When the left long press input is acquired while the image 806 is displayed, the mobile device 310 transitions to transmission of the top page image (image 502 in this example) of the initial collaboration function while continuing to play.

Image 801 is a top page image of a music play function in the music play functions being executed. On the other hand, the image 504 is a top page image that is executing a music play function other than the music play function. The music playing function may also be being performed as music is being played to the driver. The image 801 may also contain the name of the song being played and the playing status (playing time). As described above, when the mobile device 310 acquires the long left press input in a state where the music playing function (that is, any one of the image 504 and the images 801 to 803 is displayed) is selected, the transmission of the top page image of the initial cooperation function is shifted. In the case where the music play function is selected again later, if music play is being performed at the time of the last selection, the mobile device 310 transmits the image 801 as a top page image of the music play function.

Since the image 801 is a top page image, when the mobile device 310 acquires the up short press input or the down short press input in the state in which the image 801 is displayed, the music playing function is switched to another cooperation function. When the right short press input is acquired while the image 801 is displayed, the mobile device 310 transitions to transmission of the image 803 while continuing music playback. When the mobile device 310 ends the music play (playlist is completed) with the image 801 displayed, the process shifts to transmission of the image 504. The mobile device 310 may not accept an instruction to end music play in a state where the image 801 is displayed.

A specific operation example of the message transmitting/receiving function will be described with reference to fig. 9. When the mobile device 310 acquires the right short press input in the state where the image 505 is displayed, it shifts to transmission of the image 901. The image 901 is an image for requesting a designation of a recipient from the driver. The mobile device 310 may also request the designation of the addressee from the driver by voice while transmitting the image 901. When the mobile device 310 acquires the down-press input, the right-press input, and the left-press input while the image 901 is displayed, it shifts to transmission of the image 902, transmission of the image 903, and transmission of the image 505, respectively.

The image 902 is an image containing a name of a recipient set in advance. When transferring to the transmission of the image 902, the mobile device 310 reads out the name set in advance as the recipient from the memory 313 and includes the name in the image 902. The mobile device 310 may also communicate the read addressee name to the driver by voice at the same time as the image 902 is transmitted. When the up-press input, the right-press input, and the left-press input are acquired while the image 902 is displayed, the mobile device 310 shifts to transmission of the image 901, transmission of the image 905, and transmission of the image 505, respectively.

The image 903 is an image showing a standby state of voice search. The image 903 may also contain an image representing the input direction for ending the voice search. The mobile device 310 may also notify the driver of the waiting for voice search by voice while transmitting the image 902. After transmitting the image 903, the mobile device 310 waits for voice input via the portable communication device 320. After obtaining the voice input, mobile device 310 searches for the recipient from the contact list in memory 313 based on the voice input. The mobile device 310 transitions to transmission of the image 904 if the addressee can be determined, and does not transmit a new image if the addressee cannot be determined (i.e., the vehicle 100 continues display of the image 903). The mobile device 310 may also notify the driver of the situation by voice in the event that the addressee cannot be determined. When the left short press input is acquired while the image 903 is displayed, the mobile device 310 shifts to transmission of the image 901.

Image 904 is an image containing the name of the recipient determined by the voice search. The mobile device 310 may also notify the driver of the determined addressee's name by voice while transmitting the image 904. When the right short press input and the left short press input are acquired while the image 904 is displayed, the mobile device 310 shifts to transmission of the image 905 and transmission of the image 901, respectively.

The image 905 is an image showing a standby state of voice input. The image 905 may also contain an image indicating an input direction for ending voice input and an input direction for starting transmission. The mobile device 310 may also transmit the image 905 while informing the driver of the waiting for voice input by voice. After transmitting the image 905, the mobile device 310 waits for voice input via the portable communication device 320. The mobile device 310 acquires the input voice as a message to be transmitted. When the left short press input, the right short press input, and the down short press input are acquired while the image 903 is displayed, the mobile device 310 shifts to transmission of the image 904, transmission of the image 907, and transmission of the image 906, respectively.

The image 906 is an image of a fixed sentence including a message set in advance. When transferring to the transmission of the image 906, the mobile device 310 reads out a fixed sentence of a message set in advance from the memory 313 and includes the fixed sentence in the image 906. Image 906 may also contain an image representing the input direction for canceling transmission and the input direction for starting transmission. The mobile device 310 may also notify the driver of the read fixed sentence by voice at the same time as the image 906 is transmitted. When the up-press input, the right-press input, and the left-press input are acquired while the image 906 is displayed, the mobile device 310 shifts to transmission of the image 905, transmission of the image 907, and transmission of the image 904, respectively.

Image 907 is an image representing the execution status of the messaging function. Image 907 may also contain an image representing a message being sent. The mobile device 310 starts transmitting the message to the recipient at the same time as transmitting the image 907, and shifts to transmission of the image 505 after the transmission is completed.

As shown in fig. 6 to 9, images transmitted through the respective collaboration functions (i.e., collaboration images) are classified into three levels of a menu level, an object selection level, and an activity level. In the menu hierarchy, a top page image of the collaboration function in the selection is contained. In the object selection hierarchy, an image of an execution object for selecting a collaboration function in selection is included. The activity hierarchy includes an image indicating the execution status of the selected collaboration function.

In each collaboration function having an object selection hierarchy, transition from the menu hierarchy to the object selection hierarchy is performed based on a right short press input. In addition, in each collaboration function having an activity hierarchy, transition from the object selection hierarchy to the activity hierarchy is performed based on a right short press input. In this way, since the transition of any hierarchy is performed based on the right short press input, the driver can intuitively transition the hierarchy. In addition, a switch other than a direction switch such as a decision switch is not required. Further, transition from the active hierarchy to the object selection hierarchy and transition from the object selection hierarchy to the menu hierarchy are performed based on the left short press input in the opposite direction to the right short press input. Thus, the driver can intuitively return to the hierarchy. In addition, the mobile device 310 does not perform confirmation based on the image of the driver when transferring from the menu hierarchy to the object selection hierarchy and from the object selection hierarchy to the activity hierarchy. This can reduce the amount of operations until the execution of the processing.

In each hierarchy, the up short press input and the down short press input are used for transition of processing within the same hierarchy. As described above, the left-right switch 200H is a tilt-type switch, and the upper switch 200U and the lower switch 200D are independent push-type switches. Therefore, the amount of movement of the finger of the driver in one of the left and right directions is smaller than that in the up-down direction. In the above-described embodiment, the shift between layers is performed by the input in the left-right direction, and thus the amount of movement of the finger of the driver can be reduced.

In the object selection hierarchy, transition to voice search is made based on right short press input. In this way, transition to voice search can be made based on input (right short press input) in the same direction as transition to the deep hierarchy, whereby a unified operation feeling can be provided.

A specific example of interrupt processing by the cooperation function will be described with reference to fig. 10. The interrupt process refers to a process in which the mobile device 310 requests the vehicle 100 to start the cooperative function, regardless of the instruction of the driver. For example, the mobile device 310 requests the start of the interrupt process in the case that there is an incoming call of another person or in the case that a message of another person is received.

In the case where there is an incoming call to the mobile device 310, the mobile device 310 transmits an image related to the interruption process of the call function (i.e., an interruption image) to the vehicle 100, and the vehicle 100 displays the interruption image in the area 402 of the screen 400. The interrupt image may also contain the name of the caller, an input direction for indicating a response to the call, and an input direction for indicating a non-response to the call. When a collaboration function other than the call function is selected at this time, an image having the selected collaboration function is displayed in the area 401. On the other hand, when the cooperation function is not being executed at this time, an image other than the cooperation function is displayed in the area 401. When the right short press input is acquired while the interrupt image is displayed, the mobile device 310 responds to the power-on and shifts to the transmission of the image 606. At this time, a cooperative image (specifically, image 606) is displayed in the region 401. At this time, the vehicle 100 may delete the interrupt image from the region 402 and display an image based on the non-cooperative function. The same process is also performed when the mobile device 310 receives a message.

An example of the operation of the control method of the mobile device 310 will be described with reference to fig. 11. The method may also begin with the mobile device 310 being started. The following steps of the operation are executed by the control unit 311 of the mobile device 310.

In step S1101, the control unit 311 establishes a communication link with the vehicle 100 and the portable communication device 320. As described above, the communication link may be a short-range wireless communication such as Bluetooth (registered trademark). The control unit 311 may establish a communication link with either the vehicle 100 or the portable communication device 320, or may establish both. In addition, the communication link with the portable communication device 320 may be established at the time of voice output to the portable communication device 320.

In step S1102, the control unit 311 determines whether or not an instruction to start cooperation is acquired. When this instruction is acquired (yes in S1102), the control unit 311 shifts the process to step S1103, and otherwise (no in S1102), the control unit 311 repeats step S1102. In the above example, when receiving the long left press input from the vehicle 100, the control unit 311 determines that the instruction to start the cooperation is acquired.

In step S1103, the control unit 311 transmits the top image (image 502 in the above example) of the initial cooperation function to the vehicle 100. At this time, an initial collaboration function (in the above example, a call function) is selected.

In step S1104, the control unit 311 determines whether or not an instruction to change the cooperative function being selected is acquired. When this instruction is acquired (yes in S1104), the control unit 311 shifts the process to step S1105, and otherwise (no in S1104), the control unit 311 shifts the process to step S1106. In the above example, when the up short press input or the down short press input is received from the vehicle 100, the control unit 311 determines that the instruction to change the cooperative function is acquired.

In step S1105, the control unit 311 changes the selected cooperative function, and transmits the top page image of the changed cooperative function to the vehicle 100.

In step S1106, the control unit 311 determines whether or not an instruction associated with the selected cooperative function is acquired. When the instruction is acquired (yes in S1106), the control unit 311 shifts the process to step S1107, and otherwise (no in S1106), the control unit 311 shifts the process to step S1108.

In step S1107, the control unit 311 performs processing of the cooperative function in the selection in accordance with the acquired instruction. The processing of the cooperation function is described in detail in fig. 6 to 9, and is not repeated here.

In step S1108, the control unit 311 determines whether or not an instruction to end the cooperation is acquired. When the instruction is acquired (yes in S1108), the control unit 311 shifts the process to step S1102, and otherwise (no in S1108), the control unit 311 shifts the process to step S1104. In the above example, when receiving the right long press input from the vehicle 100, the control unit 311 determines that the instruction to end the cooperation is acquired.

An operation example of the interrupt process when the call function of the mobile device 310 receives an incoming call will be described with reference to fig. 12. The method may begin with the mobile device 310 being started. The following steps of the operation are executed by the control unit 311 of the mobile device 310.

In step S1201, the control unit 311 determines whether or not an incoming call is accepted. When an incoming call is received (yes in S1201), the control unit 311 shifts the process to step S1202, and otherwise (no in S1201), the control unit 311 repeats step S1201.

In step S1202, the control unit 311 generates an interrupt image and transmits the interrupt image to the vehicle 100. The interrupt image may also contain the name of the caller, an input direction for indicating that the call is responded to, and an input direction for indicating that the call is not responded to. The control unit 311 may notify the user of the incoming call by voice while transmitting the interrupt image. When the communication link with the vehicle 100 is not established at this time, the control unit 311 establishes the communication link with the vehicle 100.

In step S1203, the control unit 311 determines whether or not an instruction to respond to the incoming call is acquired. When this instruction is acquired (yes in S1203), the control unit 311 shifts the process to step S1204, and otherwise (no in S1203), the control unit 311 ends the process. For example, the control unit 311 may consider the right short press input as an instruction to respond to an incoming call and the left short press input as an instruction to not respond to an incoming call.

In step S1204, the control unit 311 transmits an image of the active level of the call function (i.e., the image 606) to the vehicle at the same time as the call is started. Instead of transmitting the image 606, the control unit 311 may transmit the image 601. When a cooperative function other than the call function is being executed at this time, the control unit 311 may end the function according to the priority of the cooperative function being executed. For example, when the priority of the music playing function is set to be lower than the priority of the call function, the control unit 311 ends the music playing function being executed.

In step S1205, the control unit 311 determines whether or not the call is ended. When the call ends (yes in S1205), the control unit 311 ends the process, and otherwise (no in S1205), the control unit 311 repeats step S1205. After the call is completed, the control unit 311 may maintain the cooperation state with the vehicle 100 or may end the cooperation with the vehicle 100. The control unit 311 may restart the cooperation function when another cooperation function is executed at the start time of the interrupt processing.

An example of the operation of interrupt processing when the messaging function of the mobile device 310 receives a message will be described with reference to fig. 13. The method may also begin with the mobile device 310 being started. The following steps of the operation are executed by the control unit 311 of the mobile device 310.

In step S1301, the control unit 311 determines whether a new message is received. When a new message is received (yes in S1301), the control unit 311 shifts the process to step S1302, and otherwise (no in S1301), the control unit 311 repeats step S1301.

In step S1302, the control unit 311 determines whether or not the non-response setting is on. If the non-response setting is on (yes in S1302), the control unit 311 ends the process, and otherwise (no in S1302), the control unit 311 shifts the process to step S1303. The non-response setting refers to a setting as to whether or not to send an interrupt image to the vehicle 100 in the case where a new message is received. The setting may be turned on by default or by the driver. The set value may be stored in the memory 313.

In step S1303, the control section 311 determines whether or not the automatic response setting is on. If the automatic response setting is on (yes in S1303), the control unit 311 shifts the process to step S1304, and otherwise (no in S1303), the control unit 311 shifts the process to step S1305. The automatic response setting refers to a setting as to whether or not the mobile device 310 performs an automatic response in the case of receiving a new message. The setting may be turned on by default or by the driver. The set value may be stored in the memory 313.

In step S1304, the control unit 311 automatically responds to the received message. For example, the control unit 311 may return a stationary message indicating that the vehicle is being driven.

In step S1305, the control unit 311 generates an interrupt image and transmits the interrupt image to the vehicle 100. The interrupt image may also contain the name of the sender, an input direction for indicating reply messages, and an input direction for indicating no reply messages. The control unit 311 may notify the reception of the message by voice while transmitting the interrupt image. When the communication link with the vehicle 100 is not established at this time, the control unit 311 establishes the communication link with the vehicle 100.

In step S1306, the control unit 311 determines whether or not the auto read setting is on. If the auto-reading setting is on (yes in S1306), the control unit 311 shifts the process to step S1307, and otherwise (no in S1306), the control unit 311 shifts the process to step S1308. The auto-read setting refers to a setting as to whether the mobile device 310 automatically reads a message in the case that a new message is received. The setting may be turned on by default or by the driver. The set value may be stored in the memory 313.

In step S1307, the control unit 311 transmits a voice reading the received message to the portable communication device 320, and the portable communication device 320 outputs the voice to the driver. When the communication link with the portable communication device 320 is not established at this time, the control unit 311 establishes the communication link with the portable communication device 320. When a cooperative function other than the messaging function is being executed at this time, the control unit 311 may end the function according to the priority of the cooperative function being executed. For example, when the priority of the music playing function is set to be lower than the priority of the messaging function, the control section 311 ends the music playing function being executed.

In step S1308, the control unit 311 determines whether or not an instruction to reply to the message is acquired. When an instruction to reply to the message is acquired (yes in S1308), the control unit 311 shifts the process to step S1309, and otherwise (no in S1308), the control unit 311 ends the process. For example, the control unit 311 may consider the right short press input as an instruction to reply to a message, and the left short press input as an instruction to not reply to a message.

In step S1309, the control section 311 transitions to transmission of the image 905 to generate a message, and replies to the voice input message. After the message is transmitted, the control unit 311 may maintain the cooperation state with the vehicle 100, or may end the cooperation with the vehicle 100. The control unit 311 may restart the cooperation function when another cooperation function is executed at the start time of the interrupt processing.

An example of the operation of the control method of the vehicle 100 will be described with reference to fig. 14. The method may also begin with the vehicle 100 being started. The following steps of the operation are executed by the control unit 301 of the vehicle 100.

In step S1401, the control unit 301 establishes a communication link with the mobile device 310. As described above, the communication link may be a short-range wireless communication such as Bluetooth (registered trademark). The communication link with mobile device 310 may also be established at the time of sending the indication to mobile device 310.

In step S1402, the control unit 301 determines whether or not an instruction to start cooperation is acquired. When this instruction is acquired (yes in S1402), the control unit 301 shifts the process to step S1403, and otherwise (no in S1402), the control unit 301 repeats step S1402. In the above example, when the left long press input is acquired via the direction switch 200, the control unit 301 determines that the instruction to start the cooperation is acquired.

In step S1403, the control unit 301 transmits an instruction to start cooperation to the mobile device 310. The control unit 301 may directly transmit the left long press input, that is, may transmit any information that the mobile device 310 can recognize as the start of the cooperation.

In step S1404, the control unit 301 determines whether or not the cooperative image is received from the mobile device 310. When the cooperative image is received (yes in S1404), the control unit 301 shifts the process to step S1405, and otherwise (no in S1404), the control unit 301 shifts the process to step S1406.

In step S1405, the control unit 301 displays the received collaborative image on the area 401 of the screen 400 of the display device 101.

In step S1406, the control unit 301 determines whether or not a direction instruction is acquired. When the direction instruction is acquired (yes in S1406), the control unit 301 shifts the process to step S1407, and otherwise (no in S1406), the control unit 301 shifts the process to step S1408. When any one of the up-down, left-right direction input is acquired via the direction switch 200, the control unit 301 determines that the direction instruction is acquired.

In step S1407, the control unit 301 transmits the acquired direction instruction to the mobile device 310.

In step S1408, the control unit 301 determines whether or not an instruction to end the cooperation is acquired. When this instruction is acquired (yes in S1408), the control unit 301 shifts the process to step S1402, and otherwise (no in S1408), the control unit 301 shifts the process to step S1404. In the above example, when the right long press input is acquired via the direction switch 200, the control unit 301 determines that the instruction to end the cooperation is acquired.

An example of the operation of the interrupt process in the vehicle 100 will be described with reference to fig. 15. The method may also begin with the vehicle 100 being started. The following steps of the operation are executed by the control unit 301 of the vehicle 100.

In step S1501, the control unit 301 determines whether or not an interrupt image is received from the mobile device 310. When the interrupt image is received (yes in S1501), the control unit 301 shifts the process to step S1502, and otherwise (no in S1501), the control unit 301 repeats step S1501.

In step S1502, the control unit 301 displays the received interrupt image in the area 402 of the screen 400 of the display device 101.

In step S1503, the control unit 301 determines whether or not a direction instruction is acquired. When the direction instruction is acquired (yes in S1503), the control unit 301 shifts the process to step S1503, and otherwise (no in S1503), the control unit 301 ends the process. When any one of the up-down, left-right direction input is acquired via the direction switch 200, the control unit 301 determines that the direction instruction is acquired.

In step S1504, the control unit 301 transmits the acquired direction instruction to the mobile device 310.

In step S1505, the control unit 301 determines whether or not the cooperative image is received from the mobile device 310. When the cooperative image is received (yes in S1505), the control unit 301 shifts the process to step S1506, and otherwise (no in S1505), the control unit 301 ends the process.

In step S1506, the control unit 301 starts a cooperative operation with the mobile device 310. When the cooperation operation is started by the interrupt processing, the control unit 301 may end the cooperation operation after the interrupt processing is ended.

In the above-described method, the vehicle 100 displays the cooperative image and the interrupt image received from the mobile device 310 on the display device 101. Alternatively, the vehicle 100 may receive information necessary for generating the collaborative image and the interrupt image from the mobile device 310, create the collaborative image and the interrupt image using the information, and display the collaborative image and the interrupt image on the display device 101.

(second embodiment)

Next, a second embodiment will be described in the case where the display device 101 is a set of indicators. Fig. 16 illustrates a display example of display unit 304 during the cooperative operation of vehicle 100 and mobile device 310. The display device 101 includes an indicator configuration area 1600. The pointer arrangement area 1600 includes an area 1601 in which four pointers indicating states of the cooperation function are arranged. A pointer not associated with the cooperation function is arranged in a portion other than the region 1601 in the pointer arrangement region 1600. The indicator not associated with the cooperation function may be an existing indicator, and thus a detailed description thereof will be omitted.

In the second embodiment, the mobile device 310 may provide two or more of a call function, a messaging function, a music playing function, and a path guidance function. Hereinafter, a case where the mobile device 310 provides all of the four cooperative functions will be described.

The second embodiment may be similar to the first embodiment with respect to transmission of the direction instruction from the vehicle 100 to the mobile device 310. On the other hand, in the second embodiment, the mobile device 310 transmits an indication of the lighting condition of the indicator instead of transmitting the cooperative image and the interrupt image to the vehicle 100.

The operation of the second embodiment is the same as the operation described in fig. 11 to 15 of the first embodiment. The differences will be described below. Before performing the cooperative action, the vehicle 100 extinguishes all indicators within the region 1601.

Instead of transmitting the top page image in step S1103 of fig. 11, the mobile device 310 transmits information indicating the cooperative function in the selection to the vehicle 100. Instead of determining whether or not the cooperative image is received in step S1404 of fig. 14 and step S1505 of fig. 15, the vehicle 100 determines whether or not information indicating the cooperative function in the selection is received. Instead of displaying the cooperative image in step S1405 of fig. 14, the vehicle 100 lights up an indicator representing the cooperative function in the selection. For example, in a case where the call function is being selected, the vehicle 100 lights up an indicator on the upper left in the area 1601.

Instead of transmitting the interrupt image in step S1202 of fig. 12 and step S1305 of fig. 13, the mobile device 310 transmits information indicating the cooperative function requesting the interrupt to the vehicle 100. Instead of determining whether the interrupt image is received in step S1501 of fig. 15, the vehicle 100 determines whether information indicating a cooperative function requesting an interrupt is received. Instead of displaying the cooperative image in step S1502 of fig. 15, the vehicle 100 lights up an indicator indicating a cooperative function requesting interruption. For example, in the case where the call function request is interrupted, the vehicle 100 lights up an indicator on the upper left in the region 1601. When the other cooperative function is in the live state at this time, the vehicle 100 maintains the lighting of the indicator indicating the cooperative function. The vehicle 100 may not light up but blink an indicator that indicates a cooperative function that requests interruption. When the vehicle 100 ends a low priority cooperative function (for example, a music play function for interruption of a call function) at the time of interruption, an indicator indicating the ended cooperative function is turned off.

In the second embodiment, the mobile device 310 transmits information indicating the selected collaboration function and the collaboration function for which interruption is requested, instead of transmitting the collaboration image and the interruption image. Alternatively, the mobile device 310 may transmit the cooperative image and the interrupt image, and determine which indicator the vehicle 100 lights up based on the image. According to this aspect, the mobile device 310 can perform the same operation regardless of the type of the display device 101 of the vehicle 100.

In the above embodiment, the vertical direction input and the horizontal direction input can be exchanged. For example, left direction input may be used instead of upper direction input, right direction input may be used instead of lower direction input, upper direction input may be used instead of left direction input, and lower direction input may be used instead of right direction input. In response, the position of the region 401 in the screen 400 may be changed. For example, when the cooperation is started by the long press input, and the cooperation is ended by the long press input, the region 401 may be arranged on the upper side of the screen. In the above embodiment, the left direction input and the right direction input can be replaced. For example, left direction input may be used instead of right direction input, and right direction input may be used instead of left direction input. In response, the position of the region 401 in the screen 400 may be changed. For example, when the cooperation is started by the right long press input and the cooperation is ended by the left long press input, the region 401 may be arranged on the left side of the screen.

(third embodiment)

In the third embodiment, a specific process of the control unit 301 of the vehicle 100 in the guard mode will be described. Fig. 17 is a diagram illustrating a flow of processing by the control unit 301, and fig. 18 is a timing chart of processing by the control unit 301.

First, in S1701 of fig. 17, as shown in fig. 18, when the control unit 301 of the vehicle 100 receives a signal (ign_off signal) that the ignition switch is turned OFF, the control unit 301 sets a guard mode and starts the process. The processor 302 of the control section 301 starts measuring the elapsed time from the time when the guard mode is set by the internal clock.

In S1702, the control unit 301 measures the distance between the communication unit 306 of the vehicle 100 and the communication unit 323 of the portable communication device 320 (headphone) by the radio wave intensity in the wireless communication between the communication unit 306 and the communication unit 323 of the portable communication device 320 (headphone) registered in the communication unit 306 by the pairing of the short-range wireless communication.

Here, fig. 19 is a diagram schematically showing a positional relationship of the helmet 330 (portable communication device 320) with respect to the communication unit 306 of the vehicle 100. Based on the measurement result of the distance, the control unit 301 determines whether or not the portable communication device 320 (headphone) is present within a predetermined distance DS as shown in fig. 19. If the portable communication device 320 (headphone) is not present within the predetermined distance DS (S1702-no), the control unit 301 advances the process to S1709 to end the process. This process corresponds to the process 1801 of fig. 18, and when the control unit 301 determines that the communication unit 323 of the portable communication device 320 is not present within the predetermined distance DS (fig. 19) before the predetermined time elapses from the stop of the vehicle 100 (after the prevention mode is set), the control unit ends the process without sounding an alarm from the output unit 307.

On the other hand, in the determination at S1702, if the portable communication device 320 (headphone) is present within the predetermined distance DS (S1702—yes), the control unit 301 advances the process to S1703.

In S1703, the control unit 301 determines whether or not a predetermined time (for example, 10 minutes) has elapsed based on the measurement result of the time of the internal clock of the processor 302. When the measured time has not elapsed for a predetermined time (S1703-no), the control unit 301 returns the process to S1702 and repeats the same process.

On the other hand, in the determination at S1703, when the predetermined time has elapsed during the measurement time (S1703-yes), the control unit 301 advances the process to S1704.

In S1704, the control unit 301 determines whether the portable communication device 320 (headphone) is present within the predetermined distance DS as shown in fig. 19, based on the measurement result of the distance. If the portable communication device 320 (headphone) is not present within the predetermined distance DS (S1704-no), the control unit 301 advances the process to S1709 and ends the process.

For example, it is assumed that after the guard mode is set, even after a predetermined time has elapsed, for example, when the driver leaves the vehicle 100 with the helmet 330 (portable communication device 320 (headphone)), the control unit 301 does not generate an alarm in order to prevent erroneous determination in such a case.

On the other hand, in the determination at S1704, when the portable communication device 320 (headphone) is present within the predetermined distance DS (S1704-yes), the control unit 301 advances the process to S1705.

In S1705, the control unit 301 advances the process to S1706 after the sampling time (Δt: for example, 0.5 seconds) elapses based on the measurement result of the time of the internal clock of the processor 302.

In S1706, the control unit 301 determines whether the portable communication device 320 (headphone) is present within a predetermined distance DS as shown in fig. 19, based on the measurement result of the distance. When the portable communication device 320 (headphone) is present within the predetermined distance DS (S1706-yes), the control unit 301 returns the process to S1705 and repeats the same process.

On the other hand, in the determination of S1706, when the portable communication device 320 (headphone) is not present within the predetermined distance DS (S1706-no), the control unit 301 advances the process to S1707. In this case, the control unit 301 determines that the change from the presence state to the absence state of the portable communication device 320 within the predetermined distance has occurred, and advances the process to S1707.

In S1707, the control unit 301 measures the distance (first distance) and direction (first direction) between the communication unit 306 and the communication unit 341 of the electronic key 340, with respect to the distance and direction with respect to the electronic key 340, by the radio wave intensity in the wireless communication between the communication unit 306 and the communication unit 341 of the electronic key 340 registered in the communication unit 306 by the pairing of the short-range wireless communication. Further, regarding the distance and direction to the portable communication device 320, the control unit 301 measures the distance (second distance) and direction (second direction) between the communication unit 306 and the communication unit 323 of the portable communication device 320 by the radio wave intensity in the wireless communication between the communication unit 306 and the communication unit 323 of the portable communication device 320 registered in the communication unit 306 by the pairing of the short-range wireless communication.

Here, fig. 20 is a diagram schematically showing a positional relationship of the helmet 330 (portable communication device 320) with respect to the communication unit 306 of the vehicle 100 and a positional relationship of the electronic key 340 (communication unit 341) with respect to the communication unit 306.

As shown in fig. 20, the control unit 301 compares the measured distances (first distance and second distance) and further compares the measured directions (first direction and second direction) with respect to the helmet 330 (portable communication device 320) and the electronic key 340 (communication unit 341). In the comparison of the distances, when the difference (absolute value) between the first distance and the second distance is within the threshold distance, the control unit 301 determines that the first distance and the second distance are substantially equal. In the comparison of the directions (angles), when the difference (absolute value) between the first direction and the second direction is within the threshold angle as the reference, the control unit 301 determines that the first direction and the second direction are substantially equal.

In the guard mode, the control unit 301 determines that the first distance between the communication unit 306 and the communication unit 341 of the electronic key 340 and the second distance between the communication unit 306 and the communication unit 316 of the portable communication device 320 are substantially equal (S1707-yes), and when the control unit 301 determines that the first direction of the communication unit 341 for the electronic key 340 and the second direction of the communication unit 316 for the portable communication device 320 are substantially equal (S1707-yes), the control unit 301 advances the process to S1709 to end the guard mode. In this case, the driver is carrying the helmet 330 (portable communication device 320) and the electronic key 340 (communication unit 341), and the control unit 301 ends the process without issuing an alarm.

On the other hand, in the determination at S1707, when the control unit 301 determines that the measured distances (first distance and second distance) are not present at substantially the same distance (S1707-no), or when the control unit 301 determines that the measured directions (first distance and second distance) are not present at substantially the same direction (S1707-no), the processing proceeds to S1708.

In S1708, the control unit 301 controls the output unit 307 of the vehicle 100 to sound an alarm (sound an alarm), and ends the process (S1709).

As a process of determining whether or not the driver is carrying the helmet 330 and the electronic key 340, in addition to S1707—yes in the determination process of S1707, a change in the measured distance (first distance, second distance) and a change in the measured direction (first direction, second direction) may be compared, respectively, based on attenuation (change) of the radio wave intensity in the wireless communication as in S2101 of fig. 21.

For example, in S2101 of fig. 21, the control unit 301 may compare the changes in the distance (first distance, second distance) and the direction (first direction, second direction) based on the attenuation (change) of the radio wave intensity in the predetermined sampling time interval (Δt1- Δt2).

In the comparison of the changes in distance, when the difference (absolute value) between the change in the first distance and the change in the second distance, which is obtained based on the attenuation (change) in the radio wave intensity at the predetermined sampling time interval (Δt1—Δt2), is within the distance change of the threshold value as the reference, the control unit 301 determines that the change in the first distance and the change in the second distance are substantially equal. In comparison of the changes in direction, when the difference (absolute value) between the change in the first direction and the change in the second direction, which is obtained based on the attenuation (change) of the radio wave intensity at the predetermined sampling time interval (Δt1—Δt2), is within the angular change of the threshold value as the reference, the control unit 301 determines that the change in the first direction is substantially equal to the change in the second direction.

That is, when the control unit 301 determines that the change in the first distance of the electronic key 340 obtained based on the attenuation (change) in the radio wave intensity at the predetermined sampling time interval (Δt1 to Δt2) is substantially equal to the change in the second distance of the portable communication device 320 (S2101—yes), the control unit 301 further advances the process to S1709 to end the guard mode when the control unit 301 determines that the change in the first direction of the electronic key 340 obtained based on the attenuation (change) in the radio wave intensity at the predetermined sampling time interval is substantially equal to the change in the second direction of the portable communication device 320 (S2101—yes). In this case, the control unit 301 ends the process without issuing an alarm.

By combining the determination process (S2101) based on the attenuation (change) of the radio wave intensity and the determination process of S1707 of fig. 17, it is possible to determine with higher accuracy whether the driver is in a state of carrying the helmet 330 (portable communication device 320) and the electronic key 340.

On the other hand, in the determination at S2101, when the control unit 301 determines that the measured distance changes (the first distance changes and the second distance changes) are not substantially the same (S2101-no), or when the control unit 301 determines that the measured direction changes (the first direction changes and the second direction changes) are not substantially the same (S2101-no), the processing proceeds to S1708. Then, in S1708, the control unit 301 controls the output unit 307 of the vehicle 100 to sound an alarm (alarm occurrence), and ends the process (S1709).

(processing after starting the drive device 308)

Fig. 22 is a diagram schematically illustrating the process after the activation of the driving device 308, schematically showing the positional relationship of the helmet 330 with respect to the communication section 306 of the vehicle 100 and the positional relationship of the portable communication device 320 with respect to the communication section 306. At the start of driving, the driver turns on the ignition switch, whereby the driving device 308 of the vehicle 100 is started. In the positional relationship shown in fig. 22, the driver is in a state of attaching the helmet 330, and the helmet 330 is present in the vicinity of the vehicle 100, but the portable communication device 320 is in a state of not being present within the predetermined distance DS (non-present state), or a state in which the portable communication device 320 cannot be detected (non-detection state).

As a case where the portable communication device 320 is in the above-described non-existing state after the driving device 308 of the vehicle 100 is started, for example, a case where the driver forgets to take the portable communication device 320 home or the like and the portable communication device 320 is not mounted on the helmet 330. In addition, as a case where the portable communication device 320 is in the above-described non-detection state after the activation of the driving device 308, for example, a case where the portable communication device 320 is not powered on and the portable communication device 320 cannot be detected within the predetermined distance DS is described. As processing in this case, after the driving device 308 is started, the control section 301 determines whether the portable communication device 320 is present within a predetermined distance DS (whether it can be detected) within a predetermined determination time (for example, 1 minute after the start). When the control unit 301 determines that the mobile communication device 320 is in the absent state or the undetected state within the predetermined determination time, the control unit 301 generates notification information for notifying the absence state or the undetected state of the mobile communication device 320, and the communication unit 306 outputs the generated notification information to the mobile device 310. That is, when it is determined that the communication unit 323 of the portable communication device 320 is not present within the predetermined distance DS within the predetermined determination time after the driving device 308 of the vehicle 100 is started, the control unit 301 outputs notification information indicating the result of the determination to the mobile device 310 registered in the communication unit 306.

When the mobile device 310 receives the notification information, the notification information is displayed on the display unit 314 of the mobile device 310. When the communication unit 316 of the mobile device 310 receives the notification information output from the communication unit 306 of the vehicle 100, the control unit 311 of the mobile device 310 displays the notification information on the display unit 314 by, for example, lighting an indicator or displaying an icon.

When the mobile device 310 receives the notification information, the mobile device 310 notifies the reception of the notification information by sounding from the output unit 317 of the mobile device 310. When receiving the notification information from the vehicle 100, the control unit 311 of the mobile device 310 notifies the driver of the reception of the notification information by the sound generation (for example, the output of a buzzer sound or the like) from the output unit 317.

By generating the notification information by the control unit 301 of the vehicle 100, the driver can be notified of a state in which the portable communication device 320 is forgotten to be mounted or a state in which the power supply is not turned on. By preventing the driver from forgetting to attach the portable communication device 320 or from turning on the power supply, the processing of the control unit 301 in the prevention mode can be effectively utilized.
