2. Description of the Related Art Recently, mobile telephones such as portable telephones and PHSs have rapidly become widespread. The factor of this rapid spread is largely due to the convenience that information can be easily transmitted and received.

[0003] When a mobile phone receives a call while driving a vehicle, whether or not to answer the call is not particularly limited, and is left to the discretion of the driver. However, if you answer an incoming call while driving, you may be distracted by the operation or conversation and your attention to driving may be reduced. However, if the call is not answered at all while driving, for example, inconvenience may occur when the other party makes an emergency contact. Therefore, it is convenient to have a device that responds on behalf of the driver when a call is received while driving.

[0004] The present invention has been made in view of the above points, and an object of the present invention is to provide a navigation device which answers a call received while driving a vehicle on behalf of a driver. Is to do.

[0005]

In order to solve the above-mentioned problems, a navigation device according to the present invention automatically responds to an incoming call during driving by an automatic answering means, and automatically responds to the incoming call. Thus, the driver or the like is notified of this during or after the automatic response. For this reason,
You can receive calls without driver intervention,
In addition, the driver or the like can know that a call has been received during driving by being notified of the automatic response.

[0006] In particular, by automatically answering only a telephone call received while the vehicle is traveling, the driver can directly receive a telephone call when the vehicle is stopped when the driver is available. In addition, it is not always necessary to determine whether an automatic response is made depending on whether the vehicle is traveling or stopped, and an automatic response may be made when the vehicle is traveling at a predetermined speed or more. Alternatively, an automatic response may be made when a driver or the like gives an automatic response operation start instruction. in this way,
By appropriately setting the timing of the automatic response, an automatic response that is more realistic can be performed.

Further, in the navigation device of the present invention, the automatic response notifying means displays the source information including the telephone number, the name and the name of the other party after the automatic response is completed.
The driver or the like who sees this display can know who the caller is. Also, if the sender information includes a telephone number but does not include a name or name, a search is made for a telephone number book table that associates the telephone number with the name and name, so that the information of the sender can be obtained. The name and name can be easily known and displayed. The driver or the like who sees the displayed source information can take appropriate measures such as specifying the source and making a return call.

Further, the navigation device of the present invention has a so-called answering machine function of recording the voice of the other party by the voice recording means during the automatic response, and outputs the recorded content in response to a reproduction instruction from the driver or the like. Thus, the driver or the like who has heard the recorded content can know the source message without calling.

(3) Operation of Navigation Apparatus (3-1) Detailed Operation at Automatic Response The entire navigation apparatus and the navigation controller 1 have the above-described configuration. Next, a detailed operation in the case of automatically answering a call received by the mobile phone 7 while traveling will be described. FIG. 2 is a flowchart showing an operation procedure of the automatic response of the navigation device of the present embodiment. The automatic response control unit 54 constantly monitors whether or not a call signal has been sent to the mobile telephone 7 (step 101). When a call signal is sent to the mobile phone 7, a call detection signal is sent from the call / cut signal detection unit 52 to the automatic response control unit 54.

When the call detection signal is input, the automatic response control unit 54 determines whether or not the own vehicle is running (step 102). For example, the automatic response control unit 54
Monitors the vehicle speed pulse output from the distance sensor in the autonomous navigation sensor 6, and determines that the own vehicle is in a stopped state when the vehicle speed pulse is not output within a predetermined time.

When the vehicle is not running (when stopped)
Then, the process returns to step 101 and the operation of detecting the call signal is repeated. As described above, while the vehicle is stopped, even if the mobile phone 7 receives a call, the state is maintained without shifting to the incoming call operation by the automatic answering operation described below. For example, the user can press the incoming key of the mobile phone 7 to perform a manual incoming call operation on the called party to talk with the called party.

When the vehicle is running, the automatic response control unit 54 starts an automatic response process. First, the automatic response control unit 54 instructs the mobile phone 7 to perform an incoming call operation to perform an incoming call operation (step 103), and stores control data included in the call signal in the automatic answer memory 56 (step 103). Step 104). Further, the automatic response control unit 5
Reference numeral 4 outputs a response image data creation instruction to the response image drawing unit 58 indicating that an automatic response is being performed. The response image drawing unit 58 creates response image data in accordance with the instruction, and the created response image data is
And a predetermined mark indicating that the automatic response is being performed is displayed on a part of the display screen of the display device 8 (step 105). FIG. 3 is a diagram illustrating an example of a screen display during an automatic response. As shown in the figure, during the automatic response, a character of "answering" is displayed together with a telephone color mark of a predetermined color (for example, red) to notify the driver or the like that the automatic response is being performed.

Next, the automatic response control section 54 reads predetermined data for text speech from the automatic response memory 56, and reads, for example, "I cannot answer the telephone because I am driving now. Is recorded. "Is transmitted to the other party through the mobile phone 7 (step 106). Further, the automatic response control unit 54 starts recording the voice of the caller (step 107) and stores the voice signal (digital data) transmitted from the mobile telephone 7 in the automatic response memory 56. I do.

The automatic answering control unit 54 monitors the disconnection of the line via the mobile phone 7 in parallel with the voice recording operation (step 108). When the disconnection signal sent from the detection unit 52 is detected, the above-described recording operation is terminated, and a series of automatic response processing is terminated (step 109).

Next, the automatic response control unit 54 outputs an instruction to create response end image data indicating the end of the automatic response to the response image drawing unit 58. The response image drawing unit 58 generates response end image data in response to the instruction, and the generated response end image data is input to the image synthesizing unit 22 and automatically displayed on a part of the display screen of the display device 8. A predetermined mark indicating that the response has been completed is displayed (step 110). FIG. 4 is a diagram illustrating an example of a screen display after the automatic response is completed. As shown in the figure, after the end of the automatic response, a character indicating the number of the automatic responses so far is displayed together with the telephone mark of a predetermined color (for example, blue), and the driver or the like is notified. The number of cases displayed here may be various, for example, the number of cases automatically responded after the start of driving, the number of cases in which sound reproduction described below is not performed, and the like.

Next, the automatic response control section 54 determines whether or not the control data stored in the automatic response memory 56 at the time of storing the control data (step 104) includes the telephone number data of the caller as the caller information. (Step 1
11). If it is determined that the caller's telephone number data is included, the automatic response control unit 54 uses the telephone number book table set in advance by the driver or the like and stored in the automatic response memory 56, The name of the caller is specified (step 112).

FIG. 5 is a diagram showing an example of a telephone number book table. As shown in FIG.
It is composed of the caller's telephone number and the name and name. By searching the telephone number book table for a match with the caller's telephone number data included in the control data, the name and name of the other party who made the call Can be specified. The contents of the telephone number book table can be set by a driver or the like. For example, by operating the remote control unit 4 or connecting a personal computer or the like to the navigation device and transmitting data from the personal computer or the like, You can set the source phone number, name, and name.

When the control data does not include the telephone number data of the caller, or when the specification of the name based on the telephone number data is completed, the automatic response control unit 54
Automatic response data is created and stored in the automatic response memory 56 (step 113). FIG. 6 is a diagram illustrating a configuration of the automatic response data. As shown in the figure, the automatic response data is obtained by searching the "date and time of the automatic response", the "source telephone number" when the control data includes the telephone number data of the caller, and the telephone number table. If the name / name is specified, the “name / name” is specified. If the voice of the caller is recorded, the storage location (in the automatic response memory 56) of the voice data is indicated. The automatic response data is used when displaying a transmission source list, which will be described later, which includes a "pointer" and a "reproduced flag" indicating whether or not the message has been reproduced. When the creation of the automatic response data is completed, step 10
Returning to 1, the monitoring operation of the call signal and thereafter are repeated.

(3-2) Detailed Operation for Displaying Caller Information Next, display of caller information relating to a caller, reproduction of recorded voice, and transmission of a call to the caller are performed. The detailed operation in the case of performing the operation will be described. FIG. 7 is a flowchart showing an operation procedure of the navigation device according to the present embodiment, such as displaying source information. First, the automatic response control unit 54
Monitors whether an instruction to display a list of senders has been issued (step 201). When the driver or the like presses the transmission source display key of the remote control unit 4 to instruct the display of the transmission source list, the automatic response control unit 54
Determines whether the vehicle is running (step 202). For example, the automatic response control unit 54 monitors a vehicle speed pulse output from a distance sensor in the autonomous navigation sensor 6, and determines that the own vehicle is in a stopped state when the vehicle speed pulse is not output within a predetermined time. I do.

When the vehicle is running, the automatic response control unit 54 reads data for a predetermined text speech from the automatic response memory 56, and reads, for example, "Since the vehicle is currently running, the transmission source list cannot be displayed. A voice guidance signal such as "." Is generated by the voice reproduction unit 60 and output from the speaker 9 (step 221). When the vehicle is not running, the automatic response control unit 54 instructs the response image drawing unit 58 to create image data of the transmission source list. The response image drawing unit 58 reads out the automatic response data stored in the automatic response memory 56 and creates image data of a sender list, and the created image data is sent to the image synthesizing unit 22 to be displayed on the display unit. A list of sender lists is displayed on the display screen of the device 8 (step 20).
3).

FIG. 8 is a diagram showing an example of the transmission source list. As shown in the figure, the transmission source list is stored in the above-described automatic response data creation processing (step 11 in FIG. 2).
Based on the automatic response data created in 3), the names of the senders and the like are displayed in the order in which they were automatically answered, and for each sender, a number indicating the order of the automatic response, the sender's telephone number, and the name It has items such as name, presence / absence of a message (message), and if there is a message, whether the message has already been reproduced. However, not all of these items are displayed. For example, if the control data does not include the telephone number data of the caller, the name and name of the caller cannot be specified. As shown in the source information of or, only the presence or absence of the message is displayed in the source list. Although the control data includes the caller's telephone number, the corresponding caller's telephone number is not set in the telephone number book table used for specifying the name and name of the caller (step 112 in FIG. 2). In this case, since the name and the name cannot be specified, the name and the name are not displayed as shown in the source information of the number in FIG. If no voice recording (step 107 in FIG. 2) is made, the message item is displayed as “none” and the reproduction item is left blank, as shown in the source information of the number in FIG. Become.

After the transmission source list is displayed, the automatic response control unit 54 determines whether any of the displayed transmission sources has been selected by the driver or the like operating the remote control unit 4 (step S1). 204), if it is selected, then it is determined whether the play key or telephone key has been pressed (steps 205, 208).

When the play key is pressed, the automatic response control unit 54 searches the automatic response data corresponding to the selected transmission source and determines whether or not the "pointer indicating the storage location of the message" is included. The presence of voice data is determined (step 206). If the corresponding voice data does not exist, the automatic response control unit 54 reads the data for the predetermined text speech from the automatic response memory 56 and, for example, outputs a voice guidance signal such as "There is no message." 60 and output from the speaker 9 (step 222). If the corresponding voice data is present, the automatic response control unit 54 sends the corresponding voice data to the voice reproduction unit 60, outputs the recorded message voice from the speaker 9, and outputs the “reproduced A flag is set (step 207).

When the telephone key is pressed, the automatic response control unit 54 searches the automatic response data corresponding to the selected caller to determine whether or not the caller's telephone number data is included. (Step 209). If the caller's telephone number data is not included, the automatic response controller 54
Reads predetermined data for text speech from the automatic response memory 56, and generates a voice guidance signal such as, for example, "I cannot make a telephone call" by the voice reproduction unit 60 and outputs it from the speaker 9 ( Step 2
23). If the caller's telephone number data is included, the automatic response controller 54 issues a call-out operation instruction to the mobile phone 7 and makes a call to the selected caller (step 210). ).

As described above, the navigation device according to the present embodiment automatically answers a call received by the mobile phone 7 while the vehicle is running, and furthermore, displays on the display device 8 an indication to that effect. At the same time, after completion of the automatic response, the fact and the number of the automatic responses are displayed. Therefore,
Even if there is no operation by the driver or the like, it is possible to receive an incoming call during traveling, and the driver or the like can easily recognize that the automatic response has been made. Further, the navigation device of the present embodiment records the message voice of the caller, and the driver or the like can listen to the message voice as needed after the automatic answering. The case can be received reliably. Also,
Since the other party's phone number, name, and name are displayed as the caller information, it is possible to make a call again from the driver, etc., and that operation can be done just by pressing the telephone key,
Operation can be simplified.

(3-3) Modification of Operation of Navigation Apparatus Next, a modification of the operation of the navigation apparatus will be described. In the navigation device of the above-described embodiment, the vehicle automatically answers all calls received while the vehicle is traveling, and listens to a message voice or makes a call back to the caller while the vehicle is stopped. Instead of determining whether the vehicle is running or stopped, the determination may be made based on whether the vehicle is running at or above a predetermined speed.

In this case, the operation of determining whether the vehicle is running at step 102 in FIG. 2 and step 202 of FIG. 7 is replaced with the operation of determining whether the vehicle is running at a predetermined speed or higher. Just replace it. For example, the automatic response control unit 54 monitors the vehicle speed pulse output from the distance sensor in the autonomous navigation sensor 6, calculates the speed of the own vehicle according to the time interval at which the vehicle speed pulse is output, and runs at a predetermined speed. It is determined whether it is in the middle. The predetermined speed serving as a criterion for the determination can be set by the driver or the like while viewing the operation screen by operating the remote control unit 4.

Further, the remote control unit 4 is provided with, for example, an automatic / manual switching key, and when this key is pressed by a driver or the like, regardless of whether the vehicle is running or not, a telephone call can be made directly. To be able to receive
An operation for listening to a message or an operation for making a call may be performed.

FIG. 9 is a flowchart showing an operation procedure for starting and ending an automatic response according to an instruction from a driver or the like. The automatic response control unit 54 responds to an instruction from a driver or the like.
It is determined whether or not an instruction to start an automatic response operation has been issued (step 301). The driver or the like has the remote control unit 4
Select “Auto” by operating the automatic / manual switching key of
That is, when an instruction to start an automatic response operation is issued, the automatic response control unit 54 starts monitoring whether or not a call signal has been sent to the mobile phone 7 (step 302). When a call signal is sent to the mobile phone 7, the call
A call detection signal is sent from the disconnection signal detection unit 52 to the automatic response control unit 54.

When the call detection signal is input, next, the automatic response control section 54 determines whether or not an instruction to end the automatic response has been given by an instruction from the driver or the like (step 30).
3). When it is determined that the driver or the like selects “manual” by operating the automatic / manual key of the remote control unit 4, that is, when it is determined that the driver or the like has instructed the end of the automatic response, the automatic response control unit 54 returns to step 301 to detect the call. The operation is repeated. In this case, since the state is maintained without shifting to the incoming call operation by the automatic answering operation described below, the driver or the like presses the incoming key of the mobile phone 7 to make a call during this time. It is possible to perform a manual incoming call operation to the called party and talk with the called party. In addition, the automatic response control unit 54 has determined that the driver or the like has not issued an instruction to end the automatic response, that is, that the driver or the like still has the automatic / manual switching key “automatic” selected. At this time, an incoming call process is performed (step 304). The operation procedure from the incoming call processing (step 304) to the automatic response data creation (step 314) is the same as the operation procedure of steps 103 to 113 in FIG.

Automatic response data creation (step 314)
Thereafter, the automatic response control unit 54 determines whether or not an instruction to end the automatic response has been given by the driver or the like (step 31).
5). When the instruction to end the automatic response is issued, the automatic response control unit 54 performs the processing after determining whether or not the instruction to start the automatic response has been issued again (step 301), and the instruction to end the automatic response is issued. If not, the processing after the call signal monitoring operation (step 302) is performed again.

When the driver or the like selects "manual" by operating the automatic / manual key of the remote control unit 4, regardless of whether or not the vehicle is running in step 202 in FIG. It is possible to perform an operation for listening to the message of the called party, an operation for calling the called party, and the like.

The present invention is not limited to the above embodiment, and various modifications can be made within the scope of the present invention. In the above-described embodiment, the driver or the like sets the contents of the telephone number book table. For example, by searching the CD-ROM 2 in which the telephone directory is stored and searching for the contents, the telephone number data of the caller can be obtained. May be extracted from the name and displayed.

In the above-described embodiment, the name and name are specified from the telephone number by using the telephone number book table. However, by providing the navigation controller 1 with a voice recognition device, the name and name can be specified. You may. In this case, at the time of voice recording, by having the called party speak the name and name, the voice recognition device can analyze the voice and specify the name and name.

In the above-described embodiment, the notification during the automatic response and the notification of the number of the automatic responses after the end of the automatic response are performed by the screen display. By reading data for a predetermined text speech, a voice guidance signal such as “Now, an automatic response is being made” is generated by the voice reproduction unit 60, and is output from the speaker 9.
The driver or the like may be notified.

Further, in the above-described embodiment, when displaying the transmission source list, the presence / absence of a message and whether or not the message has been reproduced are displayed together with the transmission source telephone number, name, and name. Only the original telephone number or only the name / name may be displayed. FIG. 10 is a diagram showing an example of a display in a case where only a calling telephone number is displayed when the calling party list is displayed. As shown in the drawing, when the control data of the call signal does not include the source telephone number, "unknown" is displayed. FIG. 11 is a diagram showing an example of a display when only the name and the name are displayed when the transmission source list is displayed. As shown in the figure, whether the control data of the call signal does not include the source telephone number,
