Description

  The present invention relates to a vehicle operation explanation support device that is mounted on a vehicle and used when a driver receives an operation explanation of an operation unit in a vehicle compartment via communication with an external device such as a help desk where an operator resides. .

  2. Description of the Related Art In recent years, with the enhancement of functions of vehicles such as automobiles, a large number of operation units such as switches are provided around the driver's seat. For this reason, for example, a driver who rides in a car that is not on board due to car sharing or the like may not know what function the switch around the driver's seat has. Similarly, a driver who is not good at handling a machine may not know what function a switch around the driver's seat has even if it is a vehicle owned by the driver.

  As a method for solving such a problem, there is a method in which a help desk operator provided in advance as an external device of a vehicle has two-way conversation with a driver via communication to explain functions and positions of an operation unit. is there. However, the conversation is not efficient because the driver's intention is not well communicated to the operator and may take a long time. In addition, it is not preferable that the driver concentrates on the conversation and the concentration in driving decreases because the driver tries to convey his intention to the operator while the vehicle is running.

  In view of this, there has been proposed an apparatus for irradiating a laser to an operation portion of a vehicle designated by an operator through communication when the driver talks with the operator. By using this device, the driver can immediately grasp the switch designated by the operator and can receive an explanation efficiently (for example, see Patent Document 1).

JP 2008-296606 A

  However, in the invention described in Patent Document 1, even if the operation unit designated by the operator can be transmitted to the driver in an easy-to-understand manner, the position of the operation unit that the driver wants to know the function from the driver is easily transmitted to the driver. I can't. Accordingly, the present invention provides a vehicle operation explanation support device that is mounted on a vehicle and receives an operation explanation of an operation unit in a vehicle compartment via communication with an external device. The operation unit designated by the driver is sent to the external device. It was made for the purpose of smooth notification.

  In the vehicle operation explanation support apparatus of the present invention made to achieve the above object, the receiving means receives the operation explanation of the operation unit in the vehicle compartment via communication with an external device and provides it to the driver. On the other hand, the operation unit determination means detects the driver's line of sight to determine the operation unit being watched by the driver among the plurality of operation units in the vehicle interior, and the notification unit is determined by the operation unit determination unit The operation unit is notified to the external device via the communication. For this reason, the operation unit watched by the driver can be smoothly notified to the external device, and it is possible to receive an operation description more consistent with the driver's desire from the external device. If the operation unit determined by the operation unit determination unit is further provided with irradiation means for locally irradiating visible light, the driver can confirm the operation unit notified by the notification unit, and the reliability of the apparatus Will improve.

[Configuration of the embodiment]
Next, embodiments of the present invention will be described with reference to the drawings. Note that in the vehicle 1 of the present embodiment, the driver D (see FIG. 2) sets the switches 11, 12, 13,... In the vehicle interior via communication with the help desk 50 (see FIG. 3) where the operator OP resides. Some are configured to receive operation instructions.

  As shown in FIG. 1, a vehicle 1 includes an instrument panel 3 provided below a windshield 2, a driver microphone 5 for a driver D to ask questions to the help desk 50, and a help desk 50 corresponding thereto. And a driver speaker 7 that utters an answer from the user. The instrument panel 3 is also provided with a camera 9 for detecting the line of sight of the driver D. As schematically shown in FIG. 2, the camera 9 captures an image of a range including the face of the driver D, that is, an image of a range indicated by A in FIG.

  Returning to FIG. 1, a help desk call switch 10 for calling the help desk 50 is provided in the passenger compartment of the vehicle 1 together with other switches 11, 12, 13,. It has been. Further, the ceiling 20 of the passenger compartment is provided with a laser irradiation device 22 for locally irradiating laser as visible light from the laser irradiation port 21 toward the switches 11, 12, 13,.

  FIG. 3 is a block diagram illustrating the configuration of the vehicle operation explanation support device of the present embodiment provided in the vehicle 1 (hereinafter simply referred to as the vehicle interior) together with the configuration of the help desk 50 with which the device communicates. is there. The help desk 50 includes a terminal device 51 that can be operated by the operator OP at a facility provided in each region of the country or in one place in the country. The terminal device 51 can be configured by a general personal computer including a mouse and a keyboard, for example. The help desk 50 includes a help desk communication device 53 that can communicate with the in-vehicle communication device 29 mounted on the vehicle 1, and the help desk communication device 53 is connected to the terminal device 51. Communication between the in-vehicle communication device 29 and the help desk communication device 53 can be performed using various communication lines such as a telephone line and the Internet.

  Furthermore, an operator microphone 55 and an operator speaker 57 used by the operator OP are connected to the terminal device 51. The in-vehicle communication device 29 of the vehicle 1 is also connected to the driver microphone 5 and the driver speaker 7 described above. For this reason, a two-way call can be performed between the driver D and the operator OP via the communication.

  The laser irradiation controller 30 that controls the laser irradiation device 22 is configured as a microcomputer including a CPU, a ROM, and a RAM, and includes a first memory 31 and a second memory 32 that are used in processing to be described later. . Further, the laser irradiation controller 30 is provided with a timer 35 for measuring the elapsed time, and a counter 37 for setting a numerical value “1” or “2” corresponding to the first memory 31 or the second memory 32. Yes.

  Further, the on-vehicle communication device 29 and the help desk calling switch 10 are connected to the laser irradiation controller 30, and the camera 9 is connected via a line-of-sight detector 41 and a switch determination unit 43. The camera 9 captures the face of the driver D and outputs it to the line-of-sight detector 41 as described above. The line-of-sight detector 41 detects the direction of the line of sight of the driver D from the face image of the driver D and outputs the detected direction to the switch determination unit 43. Various known methods can be applied to the method of detecting the direction of the line of sight by the line-of-sight detector 41. For example, the detection is based on the relative position between the Purkinje image of the eyeball (reflected light on the corneal surface) and the pupil. The method to do is applicable. The switch determination unit 43 holds a map of switches corresponding to the direction of the line of sight of the driver D in advance, and determines the switch (any one of 11, 12, 13,...) Being watched by the driver D.

  The determination result of the switch determiner 43 is output to the laser irradiation controller 30, and the switch ID is stored in the first memory 31. That is, the first memory 31 stores the ID of the switch determined by the switch determination unit 43 that the driver has watched. The second memory 32 stores the switch ID when the operator OP of the help desk 50 makes a laser irradiation request to any one of the switches 11, 12, 13,... Via the communication. It is. The in-vehicle communication device 29 and the help desk communication device 53 not only transmit / receive voice data of a call via communication as described above, but also transmit / receive the ID of the switch.

[Process of embodiment]
For this reason, the help desk communication device 53 can communicate with the in-vehicle communication device 29. When the driver D presses the help desk call switch 10, the communication is started and the operator OP and the driver D can talk. When the operator OP designates a switch for requesting laser irradiation via the terminal device 51, the ID of the switch is sent to the laser irradiation controller 30 via the communication and stored in the second memory 32.

  The terminal device 51 includes a table in which the switch ID and the switch information are associated with each other. When the switch ID is acquired from the first memory 31 of the laser irradiation controller 30 through the communication, the terminal OP 51 Presents the switch information. Further, the laser irradiation controller 30 controls the laser irradiation device 22 by a process to be described later, and irradiates the laser whose ID is stored in at least one of the first memory 31 and the second memory 32. For this reason, the operator OP can control the irradiation position of the laser in the vehicle 1 by remote control.

  Next, details of the processing will be described with reference to the flowcharts of FIGS. When the help desk call switch 10 is pressed, the laser irradiation controller 30 starts three processes shown in FIGS. 4 to 6 in parallel. At the same time, the terminal device 51 of the help desk 50 starts the help process shown in FIG.

  The notification process shown in FIG. 4 is a process for notifying the help desk 50 of the ID of the switch determined to be watched by the driver D via the camera 9, the line-of-sight detector 41, and the switch determination unit 43. When the processing is started, first, a drive signal is transmitted to the camera 9 and the line-of-sight detector 41 in S10 (S represents a step: the same applies hereinafter), so that the camera 9 captures the face of the driver D. Then, processing for detecting the direction of the line of sight of the driver D is executed by the line-of-sight detector 41 based on the image. In subsequent S20, a process for causing the switch determining unit 43 to determine the switch being watched by the driver D according to the direction of the line of sight detected in S10 is performed by transmitting a drive signal to the switch determining unit 43. The As a determination method by the switch determination unit 43, for example, a method of determining a switch on the extension of the direction of the line of sight of the driver D as a switch that the driver D is gazing at can be applied. In S20, if there is no switch corresponding to the line of sight, it is determined that the switch is not seen.

  In subsequent S30, the switch determination unit 43 determines whether or not the switch is determined. If it is determined (S30: Y), after the ID of the determined switch is recorded in the first memory 31 in S40, if it is not determined, the process proceeds to S50. In S <b> 50, it is determined whether or not the switch ID is stored in the first memory 31. If not stored (S50: N), the process proceeds to S10 described above, and if stored (S50: Y), the process proceeds to S60.

  In S60, after the switch ID stored in the first memory 31 is transmitted to the operator OP via the in-vehicle communication device 29, the process proceeds to S10 described above. Specifically, in S60, the switch ID is transmitted to the terminal device 51 via the in-vehicle communication device 29 and the help desk communication device 53, and the information is displayed on the display of the terminal device 51 and the operator OP. To be told.

  Note that the recording of the ID in S40 is performed by overwriting, and only the ID of one switch that has been most recently determined to be watched by the driver D is stored in the first memory 31. For this reason, even if the driver D moves the line of sight to the windshield 2 and continues the operation (S30: N), if the ID of the switch that has been watched so far is stored (S50: Y), the gaze is finally given. The switched switch ID is repeatedly transmitted (S60).

  The switching process shown in FIG. 5 is a process for alternately switching the numerical value set in the counter 37 between “1” and “2”. The numerical value set in the counter 37 is also used in the irradiation process (FIG. 6) described later.

  As shown in FIG. 5, when the process is started, the value of the counter 37 is reset to “1” 1 in S100. In subsequent S110, a process of resetting the timer 35 and starting time measurement is performed. Note that the timer 35 measures time in units of ms. In subsequent S120, it is determined whether or not the time measured by the timer 35 has exceeded 0.5 seconds. If it does not exceed 0.5 seconds (S120: N), the process stands by in S120, and if the time exceeds 0.5 seconds (S120: Y), the process proceeds to S130.

  In S130, it is determined whether or not the numerical value set in the counter 37 is “1”. When the numerical value of the counter 37 is “1” (S130: Y), after the numerical value of the counter 37 is set to “2” in S140, the numerical value of the counter 37 is “2” (S130: N). ) After the numerical value is set to “1” in S150, the process proceeds to S110 described above. Thus, by repeatedly executing the processing of S110 to S150, the numerical value of the counter 37 is alternately switched between “1” and “2” every 0.5 seconds.

  The irradiation process shown in FIG. 6 is a process for irradiating a laser whose ID is stored in at least one of the first memory 31 and the second memory 32 via the laser irradiation device 22. Since this process is closely related to an instruction from the terminal device 51 of the help desk 50, the help process by the terminal device 51 shown in FIG. 7 will be described first.

  As shown in FIG. 7, in this process, communication between the in-vehicle communication device 29 and the help desk communication device 53 is first started in S800. As a result, the sound input to the operator microphone 55 is output from the driver speaker 7, and the sound input from the driver microphone 5 is output from the operator speaker 57, so that the operator OP and the driver D are mutually connected. You can call.

  In subsequent S810, whether the switch ID is stored in the first memory 31 of the laser irradiation controller 30 by checking whether the switch ID is transmitted by the processing of S60 in the laser irradiation controller 30 described above. It is determined whether or not. If the switch ID is stored in the first memory 31 (S810: Y), the process proceeds to S820 after S811 is executed. If the switch ID is not stored (S810: N), the process is directly performed in S820. Migrate to

  In S811, the switch ID stored in the first memory 31 is displayed on the display of the terminal device 51 or the like. Thus, the operator OP can know the switch that the driver D wants to convey, more precisely the switch that is determined to be watched by the driver D (hereinafter also referred to as a determination switch).

  In S820, it is determined whether or not the operator OP has input the ID of the switch to irradiate the laser to the terminal device 51. When the operator OP has input the switch ID to the terminal device 51 (S820: Y), the process proceeds to S830 after S821 is executed, and when the operator OP has not input (S820: N), the process is The process proceeds to S830 as it is.

  In S <b> 821, the ID of the input switch is transmitted from the terminal device 51 to the laser irradiation controller 30 via communication, and the laser irradiation controller 30 stores the ID in the second memory 32. As a result, the laser irradiation controller 30 can receive the ID of a switch (hereinafter also referred to as a “designated switch”) designated by the operator OP to irradiate the laser by referring to the second memory 32.

  In S830, it is determined whether or not the operator OP has input a laser irradiation sharing request to the terminal device 51. If the operator OP has input a laser irradiation sharing request (S830: Y), the process proceeds to S840 after S831 is executed. If not (S830: N), the process proceeds to S840 as it is. Transition.

  In S831, a laser irradiation sharing request as a command is transmitted from the terminal device 51 to the laser irradiation controller 30 via communication. As a result, the laser irradiation controller 30 executes a process of irradiating the designated switch with a laser in common by a process described later.

  In S840, it is determined whether or not the operator OP has input a laser irradiation switching request to the terminal device 51. If the operator OP has input a laser irradiation switching request (S840: Y), the process proceeds to S860 after S841 is executed. If not (S840: N), the process proceeds to S860 as it is. Transition.

  In S <b> 841, a laser illumination switching request as a command is transmitted from the terminal device 51 to the laser irradiation controller 30 via communication. As a result, the laser irradiation controller 30 executes a process of irradiating the designated switch with the laser by switching, as will be described later.

  In S860, it is determined whether or not the operator OP has disconnected the communication by operating the terminal device 51. If the communication is not disconnected (S860: N), the process proceeds to S810 described above. If the communication is disconnected (S860: Y), the process proceeds to S870. In S870, the help process is finished, and the help of the help process is notified to the laser irradiation controller 30 via communication.

  In the irradiation process executed by the laser irradiation controller 30 in parallel with the process of the terminal device 51, as shown in FIG. 6, first, in S200, the in-vehicle communication device 29 and the help desk communication device 53 Communication between is started. This process is the same as the process of S800 described above in the terminal device 51.

  In the subsequent S210, it is determined whether or not a laser irradiation sharing request or a laser irradiation switching request is transmitted from the operator OP (specifically, from the terminal device 51) via the in-vehicle communication device 29 in S831 or S841 described above. . If there is no request (S210: N), the process proceeds to S230, and whether or not the switch ID is stored in the first memory 31 is determined by the process of S40 described above. If stored (S230: Y), the laser corresponding to the ID is irradiated with the laser via the laser irradiation device 22 in S260, and the process proceeds to S270. If the switch ID is not stored in the first memory 31 (S230: N), the process proceeds to S270 as it is.

  In S270, it is determined whether or not the end of the help process has been notified from the terminal device 51 by the process of S870 described above. If the help process has not been completed (S270: N), the process proceeds to S210 described above. To do. For this reason, when the request from the operator OP is not transmitted (S210: N), it is determined that the driver D is gazing and only the determination switch stored in the first memory 31 is irradiated with the laser.

  On the other hand, when a request is transmitted from the operator OP (S210: Y), the process proceeds to S310, and it is determined whether or not the request is a laser irradiation shared request. If it is a laser irradiation shared request (S310: Y), the process proceeds to S320, and it is determined whether or not the value of the counter 37 that is switched in the process of FIG. 5 described above is “1”. When the value of the counter 37 is “1” (S320: Y), the process proceeds to S230 described above, and the determination switch held in the first memory 31 is irradiated with the laser.

  When the value of the counter 37 is “2” (S320: N), the process proceeds to S340, and it is determined whether the switch ID is stored in the second memory 32 by the process of S821 described above. Is done. If stored (S340: Y), the switch corresponding to the ID is irradiated with the laser via the laser irradiation device 22 in S350, and the process proceeds to S270 described above. In other words, the laser is irradiated to the designated switch designated by the operator OP. On the other hand, if the switch ID is not stored in the second memory 32 (S340: N), the process proceeds directly to S270.

  That is, when there is a laser irradiation sharing request from the operator OP (S210: Y, S310: Y), the determination is made every 0.5 seconds (see FIG. 5) by repeatedly executing the processes of S210 to S350. The switch and the designated switch are alternately irradiated with laser in a time division manner. Note that it is desirable that the laser irradiation by S260 and the laser irradiation by S350 be different in the irradiation mode, such as changing the laser color or changing one to pulsed irradiation. By doing so, the driver D can easily determine which switch is the determination switch and which switch is the designated switch.

  On the other hand, when there is a laser irradiation switching request from the operator OP (S210: Y, S310: N), the process proceeds from S310 to S340 as it is, and only the designated switch is irradiated with the laser. For this reason, for example, when the operator OP designates the switch 11 and transmits a laser irradiation switching request after the driver D gazes at the switch 13 (S210: Y, S310: N), as illustrated in FIG. The laser is irradiated only to the switch 11 (S350). On the other hand, when the driver OP gazes at the switch 13 and the operator OP designates the switch 11 and transmits a laser irradiation sharing request (S210Y, S310: Y), as illustrated in FIG. Are alternately applied to the switch 11 and the switch 13 (S260, S350).

  As described above, the explanation is made while appropriately irradiating the lasers to the switches 11, 12, 13,... Necessary for the operation explanation, and then the operator OP disconnects the communication (see S860), thereby completing the help process. Then (S270: Y), the process proceeds to S380. In S380, the help process is terminated, and the process ends. At the same time, the notification process and the switching process shown in FIGS. 4 and 5 are also terminated.

[Effects of the embodiment and modifications thereof]
Thus, in this embodiment, not only the switch designated by the operator OP of the help desk 50 but also the switch watched by the driver D can be irradiated with the laser, and the ID of the watched switch is assigned to the help desk 50. Can be notified. Therefore, as in the following usage example, it is possible to smoothly receive an operation description that matches the desire of the driver D from the help desk 50.

  For example, the driver D presses the help desk call switch 10 to start a conversation with the operator OP. When the driver D gazes at the switch 11, the switch 11 is irradiated with a laser (S 260), and the switch 11 is easily seen by the driver D. The driver D can also know that the switch 11 he / she has watched is correctly recognized. At the same time, the ID of the switch 11 is notified to the operator OP (S60). In this way, the driver D and the operator OP can share information on the switch 11 that the driver D is watching. In addition, since the driver D can confirm that the driver D has accurately observed that the driver 11 has gazed, the reliability of the apparatus is also improved.

  Next, when the driver D gazes at the switch 12, the switch 12 is similarly irradiated with laser (S260), and the switch 12 becomes easy to see when the driver D sees it. At the same time, the ID of the switch 12 is notified to the operator OP (S60). In this way, the driver D and the operator OP can share the information of the switch 12 being watched by the driver D.

  Further, the laser can be controlled from the operator OP, and when the “laser irradiation switching request” is transmitted from the terminal device 51 (S841), the laser is irradiated to the switch designated by the operator OP (S350).

  When the operator OP transmits a “laser irradiation sharing request” from the terminal device 51 (S831), the designation switch designated by the operator OP and the determination switch watched by the driver D are time-shared using different colors. Irradiate (S260, S350).

  For this reason, for example, such exchange is possible. The driver D calls the help desk 50 and asks, “Which switch can open the driver's seat window?” While gazing at the switch 12. The switch 12 is irradiated with a blue driver laser, and the driver D and the operator OP can share information. The operator OP outputs a laser irradiation switching request from the terminal device 51 so that the laser irradiated to the switch can be controlled on the operator OP side, and replied, “It is a function to open the passenger seat window”. Answering "This is the driver's seat switch" while irradiating the red laser. The driver D turns the line of sight toward the switch 13 and confirms the switch 13. In this way, conversations are exchanged smoothly.

  Furthermore, the following exchanges are also possible. The driver D calls the help desk 50 and asks "Can I use the navigation if I press this button?" The switch 12 is irradiated with a blue driver laser so that the driver D and the operator OP can share information. The operator OP outputs a laser irradiation shared request from the terminal device 51, and while irradiating the switch 12 with the laser in blue, the switch 13 is irradiated with the laser in red. “Yes. "The power will be turned on." In addition, "The switch illuminated in red is a talk switch for navigation, so if you press it, you can operate by voice recognition", the conversation will be smooth.

  In the above embodiment, the help desk 50 is an external device, the in-vehicle communication device 29 and the driver speaker 7 are receiving means, the camera 9, the line-of-sight detector 41, and the switch determining device 43 are operating portion determining means, and laser irradiation. The controller 30 and the in-vehicle communication device 29 correspond to the notification unit, and the laser irradiation device 22 corresponds to the irradiation unit. The present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the gist of the present invention. For example, as the operation unit, various operation units such as a lever and a dial are assumed in addition to the switch. The external device does not necessarily require an operator, and may be a personal computer or the like that stores a voice message. In that case, the watched operation unit may be unilaterally explained.

  In addition, as described in the above embodiment, in the present invention, when an irradiation switching request is transmitted from an external device, visible light can be irradiated from the external device to the designated operation unit, while switching the operation unit to be irradiated. One irradiation means can be used. In addition, when an illumination sharing request is transmitted from an external device, when the irradiation of visible light to the determination operation unit and the irradiation of visible light to the designated operation unit can be executed in a time-sharing manner in mutually different manners, a plurality of operation units are It becomes easy to explain with entanglement.
