In the embodiment mobile phone, the Bluetooth device 19 communicates with a mobile phone having various Bluetooth connection functions by wireless connection.

  Specific processing performed by the control circuit 20 executing the program includes voice recognition processing, current position specifying processing, guidance route calculation processing, route guidance processing, hands-free processing, and the like.

  The voice recognition process performs a known voice recognition technique using a voice recognition dictionary recorded in the control circuit 20 on the voice received from the voice circuit 14, thereby converting the voice of a vehicle occupant such as a driver into a character string. Is a process of converting to a word consisting of This voice recognition process is executed to accept a driver's voice input. In the following, driver input refers to driver input using voice recognition or operation switch group 12.

  The current position specifying process is a process for specifying the current position and direction of the vehicle based on a signal from the position detector 11 using a known technique such as map matching.

  The guidance route calculation process is a process of receiving a destination voice input by a driver and receiving a destination input by operating the operation switch group 12, and calculating an optimum guidance route from the current position to the accepted destination. .

  In the route guidance process, map data is read from the external storage unit 18 and an image in which the calculated guidance route, destination, stopover, current position, etc. are overlaid on the map indicated by this map data is output to the image display device 13. In this process, a guidance voice signal instructing a right turn, a left turn or the like is output to the voice circuit 14 when the host vehicle needs to arrive before the guidance intersection. By executing this route guidance process, the control circuit 20 functions as an example of route guidance means.

  In the hands-free process, a voice signal received from a mobile phone connected via Bluetooth via the Bluetooth device 19 is output to the voice circuit 14 and the voice of the user in the vehicle detected by the microphone 14b is output. This is a process of transmitting a voice signal based on a telephone call partner via the Bluetooth device 10 and the mobile phone.

  In addition, the control circuit 20 executes programs 100 to 600 as shown in FIGS. 3 to 6 as processing related to the hands-free processing, thereby realizing various responses to incoming calls to the mobile phone. It is supposed to be.

  First, the control circuit 20 is configured to repeatedly execute the incoming call reception program 100 shown in FIG. 2 when connected to the mobile phone via the Bluetooth device 19. At 110, whether or not there is an incoming call to the mobile phone is determined based on a signal from the mobile phone, and this determination is repeated until there is an incoming call.

  When there is an incoming call, in step 120, an incoming notification is sent to the driver. Specifically, the fact that there was an incoming call, and the telephone number, name, and e-mail address characters (or voice information) of the incoming call are output to the image display device 13 (or voice circuit 14). To do. The telephone number is received from the mobile phone together with an incoming call signal. The name and the e-mail address may be received from the mobile phone together with the incoming call signal, or a table in which the telephone number, the name, and the e-mail address are recorded in the external storage unit 18 in association with each other. If there is, the name and electronic mail address corresponding to the received telephone number may be specified based on the table.

  Subsequently, in step 130, the risk level is determined. The risk level determination is a process for determining whether it is dangerous for the driver to make a telephone call using the hands-free function. Specifically, this determination is made based on the running state of the vehicle and the input by the driver. For example, the driver's margin for driving is calculated based on the difficulty level of driving on the road, whether automatic steering is performed, whether there are pedestrians around, etc., and based on the margin When the driving load of the driver is higher than a predetermined standard, it is determined that the driver is dangerous. Otherwise, it is determined that the driver is not dangerous. The degree of difficulty in driving the road is determined based on the map data in the external storage unit 18 and information from the VICS receiver 15, the type of road (highway, city street, etc.), curvature, width, number of lanes, Specify based on the degree of congestion. Further, whether or not there are pedestrians around is determined based on, for example, an image from a front photographing camera (not shown) mounted on the vehicle.

  For example, when the traveling road is an expressway, it may be determined that it is not dangerous, and when the traveling road is an urban road, it may be determined that it is dangerous. Also, for example, the driver may determine that it is not dangerous for the driver to make a telephone call based on the input of a voice to the effect that the driver can perform a hands-free call. It may be determined that it is dangerous for the driver to make a telephone call based on the input of voice or the like to the effect.

  Subsequently, in step 140, if the determination result in step 130 indicates that there is no danger, it is determined that a hands-free call can be started, and the process proceeds to step 150. Also, in step 140, if the determination result in step 130 indicates that it is not dangerous, it is determined that the hands-free call cannot be started, and the process proceeds to execution of step 170, thereby transitioning to a dangerous answerback mode. . In addition, when proceeding to Step 170, notification by voice, image, light (for example, LED), etc. for entering the answer-back mode in danger may be performed.

  In step 150, the mobile phone is controlled to open the line related to the incoming call (that is, off-hook). Subsequently, in step 160, the above-described hands-free processing using the line is started, and then the incoming answering program 100 is started. The execution of one time is finished.

  In step 170, a mode selection input by the driver is accepted. Specifically, the modes that can be selected are a little waiting mode (corresponding to an example of the second mode), an arrival time mode, an immediate stop notification mode (corresponding to an example of the first mode), and after the stop There is a notification mode (corresponding to an example of the first mode). Subsequently, in step 180, the mode is changed to the mode selected in step 170 (corresponding to an example of the selection mode), and then execution of the incoming answering program 100 for one time is terminated.

  When the voice input (corresponding to an example of the input by the driver for selecting the standby request notification) is performed by executing the steps 170 and 180, for example, when the driver utters “Waiting”, the operation shown in FIG. Execution of the waiting mode program 300 starts. For example, when the driver inputs a voice by saying “arrival time”, the execution of the arrival time mode program 400 shown in FIG. 4 starts. Also, for example, when voice input (corresponding to an example of input by the driver for selecting a stop-by notification) is performed by the driver saying “Short-stop location notification”, the stop-point immediate notification mode program shown in FIG. 500 runs begin. Further, for example, when voice input (corresponding to an example of input by the driver for selecting a stop-by notification) is performed by a driver saying “after stop-by”, a notification mode after stop-by shown in FIG. Execution of the computer program 600 starts.

  The processing contents of the control circuit 20 that executes the program of each mode will be described below. In the execution of the program 300 for waiting mode, the control circuit 20 first controls the mobile phone to open the line related to the incoming call in step 305, and then starts the timer in step 310 to measure the time. To start.

  Subsequently, in step 320, a waiting image and character data (corresponding to standby request information) are transmitted to the mobile phone of the transmission source through the opened line. The mobile phone of the transmission source may display the image on the liquid crystal display when receiving the image data via the telephone line, and display the character on the liquid crystal display when receiving the character data via the telephone line. It can be done. The waiting image data to be transmitted may be an image photographed by a camera attached to the mobile phone connected to the vehicle navigation apparatus 1 or an image recorded in advance in the external storage unit 18. Further, as the character data, data that asks the caller of this incoming call to wait as it is is used, such as “Please wait for a while”. In step 320, voice data or music data for requesting to wait for the caller of the incoming call may be transmitted.

  Subsequently, in step 325, the risk determination equivalent to step 130 of the incoming call reception program 100 is performed, and then in step 330, it is determined whether or not a hands-free call equivalent to step 140 can be started. Then, step 340 is executed, and if the call can be started, then hands-free processing is started in step 350, and the execution of the waiting mode program 300 is finished.

  In step 340, it is determined whether or not the timer started in step 310 has expired, that is, whether or not the reference time has elapsed since the start of timer measurement. If the timer has expired, step 360 is executed, and the timer has not expired. If so, step 320 is executed again. The reference time may be a fixed value stored in advance, may be a value that varies based on various conditions, or may be a value that is randomly determined within a certain range. . Note that the fluctuation based on various conditions may be, for example, a fluctuation based on a driver's setting input, or a smaller vehicle speed.

  In step 360 after the timer expires, a notice to end the waiting mode is output to the image display device 13 and the audio circuit 14 as images and audio, respectively, and in step 370, an input of mode selection by the driver is accepted. There are three modes that can be selected here: arrival time mode, stop-by-stop notification mode, and post-stop-notification mode. Subsequently, in step 380, execution of the program corresponding to the mode selected in step 370 is started, and then execution of the waiting mode program 300 is ended.

  When the control circuit 20 executes such a waiting mode program 300, the vehicular navigation apparatus 1 opens a line on which a call is received in the waiting mode when a call is received (step 305). (See step 325, 330) or until the reference time elapses (see steps 310, 340), wait for the incoming caller as it is until the driving margin increases and the call can be started (see steps 310, 340). The requested waiting request information is continuously transmitted (see step 320). When the call can be started, a hands-free call is started (see step 350). In addition, if the reference time elapses before the call can be started, the mode selected by the driver among the arrival time mode, immediate stop mode notification mode, and post-stop mode (collectively referred to as “later mode”) (See steps 360 to 380).

  The control circuit 20 connects the audio data received from the audio circuit 14 so that a call between the driver and the user of the source mobile phone cannot be realized while steps 320 to 340 are being executed. The voice data from the caller received from the mobile phone is not output to the voice circuit 14 without being output to the mobile phone.

  In the execution of the arrival time mode program 400, the control circuit 20 first controls the mobile phone to open the line related to the incoming call in step 410, and then in step 420 predicts the arrival at the destination. The time is calculated, and the calculated arrival time is transmitted as character data or voice data to the mobile phone of the caller via the opened line. Subsequently, in step 430, the mobile phone is controlled and opened. Disconnect the connected line (ie, go on-hook). The expected arrival time at the destination is specified based on the current average traveling speed of the host vehicle and the length of the guide route to the destination. Note that if the destination is not set, step 420 is not executed.

  In the execution of the stop-by-stop immediate notification mode program 500, the control circuit 20 first uses the image display device 13 and the audio circuit 14 to perform a display prompting the driver to specify a stop-by place for telephone reception in step 510. Then, after waiting for the designation input of the stop by the driver (for example, by voice) and receiving the input, in step 520, the route to the specified stop is calculated by the above-described guidance route calculation processing. Note that the stop-in place may be input by specifying a unique name or by specifying a genre such as a parking lot or a park. When a genre is specified, the stopover destination of the route calculation target may be, for example, a facility closest to the current guidance route among facilities applicable to the genre, or a facility closest to the current position. Good. Further, in the route guidance executed in parallel with the stop location immediate notification mode program 500, the guidance route to the stop location is subsequently guided.

  Subsequently, in step 530, the mobile phone is controlled to open the line related to the incoming call. In step 540, the name of the designated stopover and the expected arrival time at the designated stopover are displayed as characters, images, or As voice information, the information is transmitted to the mobile phone through the opened line. Here, the estimated arrival time at the designated stop may be specified based on the current average traveling speed of the host vehicle and the length of the guide route to the designated stop. A method may be used.

  Subsequently, in step 550, the open line is controlled by controlling the mobile phone, and in step 570, the current position of the host vehicle waits for arrival at the designated stop-off place. Then, a call is made to the telephone number of the mobile phone of the caller, that is, dialing is performed to open the telephone line, and then hands-free processing is started in step 590, and then execution of the stop-by-stop notification mode program 500 is terminated. .

  When the control circuit 20 executes the stop location immediate notification mode program 500 as described above, the vehicular navigation apparatus 1 can be used for a telephone response by a driver in the stop location immediate notification mode when there is an incoming call. Accepts the designation of the stopover (see step 510), calculates the route to the designated stopover (see step 520), temporarily opens the telephone line associated with the incoming call, and predicts the expected arrival time to the designated stop When information is transmitted to the caller via the line (see steps 530, 540, and 550) and then arrives at the designated stopover (see step 570), a hands-free call with the mobile phone of the caller is automatically made. Start (see steps 580 and 590).

  Further, in the execution of the notification mode program 600 after the stop-off, the control circuit 20 first controls the mobile phone to open the line related to the incoming call in step 605, and then in step 610, “can call” The voice, character string, or image that says "we will tell you the time later" is sent to the mobile phone through the line, and then in step 615, the connected mobile phone is controlled to disconnect the open line. To do.

  Subsequently, at step 620, designation of a stop-by place is accepted by a process equivalent to step 510, and further at step 625, a route to the designated stop-by place is calculated by a process equivalent to step 520. Subsequently, in step 630, the name of the designated stopover place and the expected arrival time at the designated stopover place are transmitted by e-mail to the e-mail address of the mobile phone as information by text, image or voice. Note that this mail transmission may be performed by controlling the mobile phone connected thereto, or the vehicle navigation apparatus 1 may perform e-mail transmission by itself using a wireless LAN interface or the like (not shown). It may be. Further, the expected arrival time is specified by the same processing as in step 540. The e-mail address of the caller's mobile phone may be received from the mobile phone together with the incoming call signal, or the external storage unit 18 is associated with the telephone number, name, and e-mail address. If there is a recorded table, an e-mail address corresponding to the received telephone number may be specified based on the table.

  Subsequently, in step 640, the process waits until the current position of the host vehicle arrives at the designated stop, and then, in step 645, dials the telephone number of the mobile phone of the caller to open the telephone line, After the hands-free process is started in step 650, the notification mode program 600 is terminated after the stop-by.

  When the notification mode program 600 control circuit 20 is executed after the stop as described above, the vehicular navigation apparatus 1 can receive the telephone line related to the incoming call in the notification mode after the stop when there is an incoming call. Is temporarily opened, and information on the stop-by location is sent to the caller via the line (see steps 605, 610, and 615), and then the driver specifies the stop-by location for telephone reception. (See step 620), calculate the route to the designated stop (see step 625), and send information such as the expected arrival time to the designated stop to the mail address of the source mobile phone (step 630). After that, when you arrive at the designated stopover location (see step 640), you will receive hands-free communication with the mobile phone of the sender. Automatically start (see step 645 and 650).

  In step 410 of the arrival time mode program 400, step 530 of the stop-by-stop immediate notification mode program 500, and step 605 of the post-stop-notification mode program 600, the line with the source mobile phone has already been opened. If there is an error (specifically, when a transition is made from a little waiting mode), it is not necessary to perform the process of opening the line again.

  As described above, the vehicular navigation device 1 that realizes a hands-free function by wirelessly connecting to a mobile phone via Bluetooth, when receiving an incoming call to the connected mobile phone (see step 110), Notification (see step 120) and if it is determined that it is dangerous for the driver to make a telephone call using the hands-free function (see steps 130 and 140), a little waiting mode, arrival time mode, stop-by-stop notification mode, Based on the input by voice or operation switch group 12 for selecting any one of the notification modes after the stop (see step 170), the selected mode is applied to the mobile phone of the transmission source. Information transmission is performed (see step 180). In this way, the driver can appropriately select a response method for a telephone that cannot be answered immediately.

  In the short wait mode, the mobile phone is controlled to open a line for incoming calls, and a camera-captured image or the like that requests the caller of the incoming call to wait as it is is transmitted through the opened line. This makes it possible for the driver to act in accordance with his willingness to respond to the incoming call at an appropriate location in the vicinity. This mode is convenient if you select the mode when the person you are calling is an important person and you want to respond immediately.

  Also, in the waiting mode, the waiting request information is first transmitted to the caller mobile phone, and the reference time elapses after the reference time has passed without the line related to the incoming call being opened. The mode is shifted to “mode” and information indicating that the driver cannot immediately respond is transmitted (steps 540, 610, and 420). In this way, if a driver falls into a situation where he / she cannot respond to the incoming call despite the driver's intention to respond to the incoming call at an appropriate location in the vicinity, Since information indicating that a response cannot be made immediately is transmitted to the caller of the incoming call, it is not necessary to wait for the user of the caller.

  Also, in the stop-in immediate notification mode, the driver accepts designation of a stop-by location for telephone reception, and returns information on the time taken to reach the stop-off location to the caller. In this way, it is possible to perform an operation in line with the driver's will to stop at the stop and respond to the incoming call.

  In the post-stop notification mode, the incoming line is temporarily opened, and information about the stop-off location is notified later by voice, and then the stop-by location specified by the driver is sent. Information on the time taken to reach is returned to the sender. Such a function is convenient if you want to notify the information about the stop location for the time being, for example, because the driver is confused about selecting the stop location and does not want to wait for the other party. It is.

In this way, even if the driver's destination is far away, he / she can find a stop and tell the person who made the call when and where the call can be made again in a short time. Therefore, if the driver does not return the phone as soon as possible, the driver will not be impatient and will be mentally stable and maintain safe driving. On the other hand, the person who makes a call can get a sense of security by being notified in a short time how long he / she can talk.
(Second Embodiment)
Next, a second embodiment of the present invention will be described. The hardware configuration of this embodiment is the same as that of the first embodiment. Further, the operation of the control circuit 20 in the present embodiment executes the arrival time mode program 700 shown in FIG. 7 instead of the arrival time mode program 400 shown in FIG. 8 is executed instead of the mode program 500, and the post-stop-notification mode program 600 shown in FIG. 9 is used instead of the post-stop-notification mode program 600 shown in FIG. The second embodiment is the same as the first embodiment except that the application program 900 is executed. In each of the programs 400 to 900, the processing contents of the steps assigned with the same step number are the same, and the description of the details of those processes is omitted here.

  In the execution of the arrival time mode program 700 of FIG. 7, the control circuit 20 opens the incoming line (see step 410) and sets the expected destination arrival time to the incoming call originator as in the first embodiment. Transmit (see step 420), and then disconnect the line (see step 430).

  Control circuit 20 then determines in step 740 whether a response to the source is unnecessary. This determination is made based on whether or not a signal indicating that no response is required is received through the line during the period until the line is opened by the process of step 410 and closed by the process of step 420. The signal indicating that the response is unnecessary may be, for example, a tone signal indicating that the transmission source user has pressed a specific key.

  If a signal indicating that no response is required is received during this period, it is determined that a response to the caller is not required, and then step 750 is executed, and no signal indicating that no response is required is received during this period. In this case, it is determined that a response to the transmission source is necessary, and then the execution of the arrival time mode program 700 is terminated.

  In step 750, the driver is notified that no response is required. This notification may be realized by outputting an audio signal indicating that no response is required to the audio circuit 14 or by displaying characters indicating that no response is required on the image display device 13. . After step 750, the execution of the arrival time mode program 700 is terminated.

  In this way, the answering back by the vehicle navigation device 1 is performed to the effect that the user of the incoming call does not need a response after arrival at the destination to the vehicle navigation device 1. Can be communicated over the line. Then, the vehicle navigation device 1 can notify the driver that the user who received the incoming call does not need a response. Therefore, the driver does not make a telephone call as a response to the calling user after arriving at the destination although not desired.

  Further, the control circuit 20 accepts designation of a stop-by area for telephone reception by the driver in the execution of the stop-point immediate notification mode program 800 of FIG. 8 (see step 510), as in the first embodiment. The route to the ground is calculated (see step 520), and the telephone line related to the incoming call is temporarily opened, and information such as the expected arrival time to the designated stopover is transmitted to the caller via the line (step 530). 540, 550).

  Control circuit 20 then determines in step 852 whether a response to the source is unnecessary. This determination is made based on whether or not a signal indicating that no response is required is received through the line during the period until the line is opened by the process of step 530 and closed by the process of step 550.

  If a signal indicating that no response is required is received during this period, it is determined that a response to the caller is not required, and then step 854 is executed, and no signal indicating that no response is required is received during this period. In this case, it is determined that a response to the caller is necessary, and then waiting for arrival at the designated stopover location (see step 570), when the call arrives, a call is automatically made to the caller (see step 580). When the line is opened, the hands-free process is started (see step 590).

  In step 854, similar to step 750, the driver is notified that no response is required. Subsequently, in step 856, a stop-in place discarding process is performed. Specifically, the route guidance to the designated stop-off place that the control circuit 20 performs is terminated, and the route guidance to the destination is resumed. After step 856, execution of the stop-by-stop immediate notification mode program 800 is terminated.

  Thus, the answering back by the vehicle navigation device 1 is performed to the effect that the user who has received the incoming call does not need a response after arriving at the place of stop to the vehicle navigation device 1. Can be communicated over the line. Then, the vehicle navigation device 1 can notify the driver that the user who received the incoming call does not need a response. Therefore, the driver does not go to the stopover place even though it is not desired, and does not make a response telephone call to the caller user at the stopover place.

  In addition, in the execution of the notification mode program 900 after the stop in FIG. 9, the control circuit 20 opens the incoming line (see step 605) as in the first embodiment, and later displays information on the stop The notification is transmitted to the source through the line (see step 610), and then the line is disconnected (see step 615).

  Control circuit 20 then determines in step 910 whether a response to the source is unnecessary. This determination is made based on whether or not a signal indicating that no response is required is received through the line during the period until the line is opened by the process of step 605 and closed by the process of step 615.

  If a signal indicating that a response is not required is received during this period, it is determined that a response to the caller is not required, and then, in step 920, a notification indicating that a response is not required is sent to the driver as in step 750. Do it.

  In step 910, if a signal indicating that no response is required is not received during the period, it is determined that a response to the caller is required, and then the driver specifies a stop-by location for telephone reception. (See step 620), calculate the route to the designated stop (see step 625), and send information such as the expected arrival time to the designated stop to the mail address of the source mobile phone (step 630). After that, when arriving at the designated stop-off place (see step 640), a hands-free call with the caller mobile phone is automatically started (see steps 645 and 650).

  Thus, the answering back by the vehicle navigation device 1 is performed to the effect that the user who has received the incoming call does not need a response after arriving at the place of stop to the vehicle navigation device 1. Can be communicated over the line. Then, the vehicle navigation device 1 can notify the driver that the user who received the incoming call does not need a response. Therefore, although the driver is not desired, the driver does not specify a stop-off location, go to the stop-off location, and further make a response phone call to the user at the stop-off location.

Further, in FIG. 7, FIG. 8, and FIG. 9, it may be possible to provide a response unnecessary determination before disconnecting the line.
(Third embodiment)
Next, a third embodiment of the present invention will be described. In the present embodiment, as a result of making a telephone call to the vehicle navigation apparatus 1, a caller user who has received a notification of an estimated arrival time and a stop-by place calls the vehicle navigation apparatus 1 again later. It is possible to make a call and tell that these notifications are unnecessary. Specifically, the present embodiment is different from the first embodiment in that the control circuit 20 executes the incoming call reception program 1000 shown in FIG. 10 instead of the incoming call reception program 100 shown in FIG. In addition,
The steps denoted by the same reference numerals in the incoming response program 100 in FIG. 2 and the incoming response program 1000 in FIG. 10 perform the same processing, and the detailed description thereof is omitted here.

  When there is an incoming call in the execution of the incoming call answering program 100 (see step 110), the control circuit 20 determines in step 1015 whether or not the incoming call is an incoming call from a telephone number to be answered. The telephone number to be answered is the telephone number of the other party on the line opened by the execution of the past programs 400 to 600. In other words, the telephone number to be answered is the telephone number to which the driver has decided to make a response telephone call later. The control circuit 20 records the telephone number of the other party on the line opened by executing the programs 400 to 600 in the RAM 16 or the external storage unit 18. When the driver makes a call to the telephone number again, the record of the telephone number is deleted. Therefore, more specifically, the telephone number to be answered is a telephone number that the driver has decided to make a response telephone call later and has not yet made a call.

  If it is determined in step 1015 that the incoming call is an incoming call from the telephone number scheduled to be answered, then in step 1020, processing for signal reception is performed. Specifically, a line is opened in response to an incoming call, and if a response is not required, a voice requesting that a predetermined operation (for example, pressing a specific key on the caller telephone) be performed is output through the line. A signal based on the operation (for example, a tone signal of a specific key) is waited for a predetermined period.

  Subsequently, in step 1030, based on the processing result in step 1020, it is determined whether or not a subsequent response is unnecessary. Specifically, if a signal based on the predetermined operation is received in step 1040, it is determined that no response is required, and if no signal is received within a predetermined period, it is determined that a response is required. If it is determined that a response is not necessary, step 1040 is subsequently executed. If it is determined that a response is required, step 120 is subsequently executed.

  In step 1040, the driver is notified that no response is required by the same method as in steps 750, 856, and 920 of the second embodiment. Subsequently, in step 1050, when a stop-by place is specified in steps 620 and 510 and route guidance to the stop-by place is performed, the guide to the stop-in place is ended. After step 1050, execution of the incoming reception program 1000 is terminated. The processing in steps 120 to 160 is the same as that in the first embodiment.

  Thus, when there is an incoming call notifying that the response is not required from the telephone number to be responded, the vehicle navigation apparatus 1 notifies the driver that there is no need to respond to the telephone number to be responded. Further, the route guidance to the stop-by place for responding to the telephone number scheduled to be answered can be terminated.

  Therefore, as a result of making a call to the vehicle navigation apparatus 1, the user of the caller who has received the notification of the expected arrival time and the stopover place makes a call to the vehicle navigation apparatus 1 again later, It becomes possible to tell that these notifications are unnecessary. In addition, the driver does not make a telephone call as a response to the caller afterward although not desired.

  In the above embodiment, the vehicle navigation device 1 corresponds to an example of an in-vehicle communication device, and the Bluetooth device 19 corresponds to an example of a connection unit. Further, the control circuit 20 functions as an example of an incoming call detection unit by executing step 110 of the incoming call reception program 100, 1000, and functions as an example of a selection receiving unit by executing step 170. Further, the control circuit 20 functions as an example of a waiting request unit by executing step 320 of the waiting mode program 300.

  Further, the control circuit 20 executes step 420 of the arrival time mode programs 400 and 700 to function as an example of an immediate response impossible notification unit and an example of a response unit.

  Further, the control circuit 20 functions as an example of the designation receiving means by executing the step 510 of the stop-by-stop immediate notification mode program 500, 800, and by executing steps 530, 540, and 550, the response means By executing step 540, it functions as an example of an immediate response impossible notification means.

  In addition, the control circuit 20 functions as an example of a response unit by executing the steps 605, 610, 615, and 630 of the notification mode programs 600 and 900 after the stop-off, and the steps 605, 610, and 615 are performed. By executing the function, it functions as an example of a response notice means. By executing Step 630, it functions as an example of a notice execution means. By executing Step 610, it functions as an example of an immediate response impossible notification means.

  Further, the control circuit 20 performs step 750 of the arrival time mode program 700, step 854 of the stop-by-stop immediate notification mode program 800, step 920 of the post-stop-notification mode program 900, and step 1040 of the incoming call reception program 1000. By executing, it functions as an example of unnecessary information notification means.

Also, the control circuit 20 functions as an example of a cancellation control unit by executing step 854 of the stop-by-stop immediate notification mode program 800 and step 1050 of the incoming call reception program 1000.
(Other embodiments)
As mentioned above, although embodiment of this invention was described, the structure of this invention is not limited only to the said embodiment, The various form which can implement | achieve the function of each invention specific matter of this invention is included. It is.

  For example, the control circuit 20 does not necessarily have to automatically dial the caller even if it arrives at a stop-off place as in steps 570 to 590 and steps 640 to 650. The driver may dial himself when he gets to the stop.

  Further, what is transmitted in steps 540 and 630 may not be the arrival time at the stop, but may be the distance to the stop, that is, when the arrival at the stop will occur (in detail Any information about the stopover that can be useful to know (whether it is rough or not). Furthermore, it may be configured to transmit only the type of stop-by location, such as information that “I will call you after arriving at a convenience store”, instead of the distance to the stop-by location and the arrival time.

  Further, the control circuit 20 disconnects the line after transmitting the character data, voice data, and image data to the point that it is not possible to immediately talk in step 360 to the mobile phone of the transmission source. Good. In this case, by executing this step 370, the control circuit 20 functions as an example of an immediate response impossible notification means.

  In step 630, the control circuit 20 dials the mobile phone of the caller to open the line, transmits information on the stop-by location using character data, voice data, image data, etc., and immediately connects the line. It may be cut.

  In addition, in steps 170 and 180 of the incoming call answering program 100, the driver speaks “Near convenience store”, thereby recognizing two words “near” and “convenience store” by voice recognition and saying “near”. Based on the recognition of the specific keyword, the stop-point immediate notification mode program 500 starts to be executed, and based on the fact that the keyword related to the facility type, “convenience store” is recognized, step 510 is omitted, At 520, a route to the nearest convenience store may be calculated.

  In addition, the control circuit 20 disconnects the line with the caller mobile phone immediately before shifting to the mode after a short wait mode, that is, immediately before step 380, and reopens the line when the “later mode” starts. It may be like this.

  In addition, the control circuit 20 does not determine whether it is dangerous for the driver to make a telephone call using the hands-free function in steps 130 and 140. If the determination in step 110 is affirmative, Step 180 may be executed immediately.

  Further, in step 380, the waiting mode may be selected again. This is useful in situations where the user still wants to continue mode after the timer expires.

  Moreover, in said embodiment, although the vehicle navigation apparatus 1 is shown as an example of a vehicle-mounted communication apparatus, the vehicle-mounted communication apparatus does not need to be the vehicle navigation apparatus 1. In that case, position information and timing information may be obtained from the navigation device. The in-vehicle communication device does not necessarily have a hands-free function, and any device that can be connected to a mobile phone and control the mobile phone is sufficient.

  Further, in the second embodiment, when the control circuit 20 receives a signal indicating that a response is not required from the source telephone before the processing for answer back in steps 420, 540, and 610, The line may be immediately disconnected without executing the process for back-up, and the process may be transferred to steps 740, 852, and 910, respectively.

  In the second embodiment, the control circuit 20 may execute the incoming reception program 1000 instead of the incoming reception program 100.
