[0002]

2. Description of the Related Art In a navigation apparatus, map data for drawing a map, place names to be displayed on the map,
Alternatively, a CD-ROM recording information data of facilities and the like,
A map / information storage medium such as a DVD-ROM;
A playback device that reads data from an information storage medium, a display device that displays a map, etc., a self-contained navigation device such as a distance sensor or a gyro, and a vehicle position detection that detects the current position of the vehicle and the azimuth of the traveling direction using a GPS receiver or the like Device, etc., read map data including the current position of the vehicle from the map / information storage medium, draw a map image around the vehicle position on the screen of the display device based on the map data, and display the vehicle position mark. By displaying the map on the display screen and scrolling the map image according to the movement of the vehicle, fixing the map image on the screen and moving the vehicle position mark, it is possible to determine where the vehicle is currently traveling At a glance.

[0003] In addition, various information such as a lot of facility-related information is recorded on an information recording medium in addition to a map, and if necessary, the information can be searched and various information can be displayed. In the facility-related information, a telephone number of each facility and the like are recorded as necessary. Further, many navigation devices can be connected to communication means such as a mobile phone and a car phone, and some of them can obtain various information from outside using the communication means. is there. Also, by using the communication means, for example, a function of "calling" is activated in a state where a predetermined facility is displayed on a display, so that a telephone number of the facility can be automatically called. Some things have been done.

[0004] The navigation device is provided with a route guidance function for enabling a user to easily travel to a desired destination without making a mistake on a road. According to this route guidance function, when a user sets a waypoint or a destination, the navigation device automatically searches for the lowest cost route from the departure point to the destination using the map information, and the search is performed. Memorize the route as a guidance route,
During driving, when the guidance route is drawn on the map image with a different color from the other routes and drawn thicker, or when the vehicle approaches within a certain distance to the intersection where the course on the guidance route should be changed, The intersection is enlarged and displayed, and an arrow or the like indicating the direction in which the course should be changed is drawn and displayed on the screen. In addition, when displaying the intersection, the intersection is displayed by a 3D display or the like in almost the same state as when the driver is actually looking ahead of the road.

[0005] In setting the waypoints and destinations as described above, a method of setting a list by narrowing down areas in order, a method of setting a specific facility by specifying a genre, and the like.
Various means have been used, but in recent years, the location can be set and registered by inputting a telephone number using a DVD-ROM or the like which records telephone number data of each company as well as each household. Such a navigation device is also commercially available. As a result, the user can easily set a large number of transit points and destinations, and the navigation device has the shortest time for the many transit points and destinations entered and registered in this way. It is possible to search for an optimal guidance route in consideration of time, shortest cost, and the like, and to provide guidance so that the user can travel along the guidance route.

[0006] The function of such a vehicle navigation device is very effective when each person travels by car or goes to a point on a road which is difficult to understand. In many cases, stores that sell products need to deliver the products, so each store or delivery company will deliver those products to the purchaser's house in order. In addition, a courier company that performs courier services delivers various items to a large number of delivery destinations in order.

At this time, it is necessary to efficiently visit each house in order within a predetermined time. Therefore, the delivery person must examine a delivery route before departing for delivery. When the navigation device is provided, when a route search is performed after inputting all the visiting places to be visited on the day, the navigation device immediately presents one or a plurality of routes considered appropriate. The user confirms this and determines the optimal route as the scheduled traveling route, and when starting the delivery, the user departs for the first destination based on the guidance route.

[0008]

As described above, in order to go around a number of destinations in sequence, each destination is registered in the navigation device as a stopover, a route search is performed, and after the optimal route is determined, the first visit is made. You will travel by car from the beginning in order to visit, but at that time all the visited places need not be away, but in practice there are many cases where you are away, and in that case, go to the house of the visited place For the first time, you know that you are out of the office, in which case you will go to the next destination for the time being and then return to that destination at the appropriate time.

[0009] At that time, it is only necessary that the next visit is relatively close and then go to the previous absence visit if the person in the house is at home, but it is difficult for the next house to be far away and return there. When
Or, when you return to the destination where you were absent again and you were absent again, you have to go to the next destination from there and go back to the home where you were away. There was a problem that could not be delivered good.

[0010] As a countermeasure, whether the destination to be visited is currently away or at home is confirmed by a mobile phone or the like, and when the home is at home, the destination is set according to the order of the planned destination set earlier. If you go to the place you visit, but do not answer the phone even if you call for a while, or if you are set to answering machine and find out that you are away, go to the next place to visit Can also.

However, it is troublesome to reconfirm the telephone number there and make a call each time the user goes to the next visit, especially when there are many visits. In particular, when a large number of telephone numbers are recorded on the information recording medium such as the DVD-ROM of the navigation device as described above, it is also possible to connect communication means such as a mobile phone to the navigation device to communicate with the outside. When you own a navigation device that can be used, you can not effectively use such a function, but you can not say that the conventional device uses it effectively .

Therefore, according to the present invention, when a number of destinations are sequentially visited by car by using a route guidance function provided by a navigation device having an external communication function, the destinations to be visited in the future Can automatically know that it is an absence, and when it is found that it is an absence, automatically change the guidance route by postponing the visiting order of the visited destination that was the absence It is an object of the present invention to provide a navigation device that can present the information and can efficiently go around all the places to visit without requiring extra trouble.

[0013]

On the basis of the vehicle position data and the operation signal, the ROM read control unit 21 operates the operation signal data line 3
9 or the vehicle position data line 19
A large amount of map data, address data, facility information data, etc., from a map / information storage medium 20 such as a DVD-ROM or a CD-ROM based on the vehicle position signal from Store in 22. Various data in the information / map buffer 22 are transmitted to the navigation control device 1 via the information / map data line 26.
It is output to various functional units within 0 and used for various purposes described later.

By inputting such various kinds of data, the navigation control device 10 can perform various operations with various functional parts provided therein. For example, in the guidance route calculation unit 30, a vehicle position signal generation is performed. The current position data is input from the unit 18 and the destination is designated from the operation signal data line 39 and the like, a stopover is specified, and a search instruction such as expressway priority is given. The result is stored in the guidance route memory 31, and the guidance route output unit 33 creates data for guiding the guidance route in various forms. Among them, the image data is stored in the image combining unit 27.
, And can be displayed on the image display device 28 while being superimposed on a map.

In the intersection guidance output section 32, the vehicle current information is obtained based on the vehicle position from the vehicle position signal generation section 18, the map data from the information / map buffer 22, and the guidance route information from the guidance route memory 31. It is determined whether or not the position has reached the vicinity of the right / left turn intersection on the guidance route.
, And to the voice synthesizing unit 59, and outputs the voice of the intersection guidance from the speaker 61 via the voice output unit 60. The intersection guidance output unit 32 performs not only the above-mentioned guidance of the intersection but also the guidance of the entrance and exit of an interchange and the guidance where there is no right / left intersection for a while.

In the map drawing section 25, based on map data of a predetermined scale in the map memory 23, for example, a bird's-eye view display, a 3D display, etc., from the operation signal input section 43 input via the display mode designation section 24 are shown. In accordance with the designation, a predetermined map is calculated and created based on the vehicle position, and further, related information data such as place name information data and facility names are superimposed on the map as necessary and displayed, and image synthesis is performed as a map image. Output to the unit 27. In addition, the image of the various mark generation units 34 and the operation screen generation unit 35 are also input to the image synthesis unit 27 as necessary.
They are combined and displayed.

The navigation control device 10 of the present invention further includes a communication unit 48 connected to the mobile phone 47, and a telephone communication execution unit 49 in the automatic visiting order change unit 60.
The user can make a call to the destination specified by the instruction. The communication signal from the other party at that time is analyzed by the telephone response analysis unit 57, and the voice signal is recognized by the voice recognition unit 58.

Since the user uses the route guidance function of the navigation device, for example, when setting a plurality of delivery destinations of goods to be delivered today, that is, destinations as a waypoint or a destination, or ending work today. For example, when pre-scheduling tomorrow, or when setting a plurality of customers scheduled to go tomorrow as visits in advance, registration of those points with the navigation device is performed in exactly the same way as the conventional waypoint and destination settings. Performed using, for example, a remote controller 40, a touch panel 41, an operation switch 42, and the like,
Alternatively, these locations can be registered by voice input from the microphone 44, and the visited locations are recorded in the visited memory 50.

In this navigation device, a telephone number of each visit required at that time is input simultaneously in order to automatically call the visit as described later. The telephone number of each visit is recorded in the telephone number memory 53 in correspondence with the visit in the visit memory. At this time,
When point search data based on a telephone number and a telephone number corresponding to a point on the map exists in the map / information recording medium 20 such as a DVD-ROM of the navigation device, the user performs this navigation when registering the visit destination. Only by inputting a telephone number necessary for the operation of the automatic visiting order change operation unit 60 in the control device 10, it is possible to simultaneously register the visiting places.

When the input of the destinations as described above is completed, the destinations of the destinations are output to the destination order setting part 51, and the points are initially transmitted to the guidance route calculating part 30 with the respective weights being equally weighted. The guide route calculation unit 30 calculates and outputs the most appropriate route under conditions such as distance priority, time priority, and charge priority input by the user before visiting each point in order. At that time, a plurality of proposals can be presented, and the user can select one of the proposals.

In the visiting order setting section 51, as described later, when a call is made to the visitor in advance and the answer is absent, a new guidance route is set in order that the visitor will go later. At this time, a condition setting is made for the order of the visits that comes after the order of the visits. Especially when there are many places to visit, it is conceivable that the places to be visited are often absent at various points in time, and it is likely that a plurality of places are also absent. An appropriate order of the destinations is set, for example, such that the later the telephone call is, the later the call is made, and the later the visit is made. The guidance route calculation unit 30 calculates a new guidance route in consideration of the condition of the order set here.

When the above-mentioned order is set in the order-of-visit-order setting section 51, only the places that have not been visited are set except for the places that have already been visited. Allows the user to calculate the guidance route for the visit destination that has not been visited yet.

The telephone contact selection section 52 selects a visit to be visited at the present time as a telephone contact based on the guide route calculated as described above,
The telephone number corresponding to the visit destination is read out from the telephone number memory 53 and output to the telephone communication execution unit 49. When the telephone contact execution unit 49 detects that the destination to be visited is out of the office as described above, the mobile phone 47 is operated again via the communication unit 48, and the calculation is performed as described above. Call the next scheduled visit immediately.

On the other hand, for example, in a state where the visits are sequentially made along the guide route calculated first, the requirement for one visit is completed and the next visit is made. At a point in time, or when requirements are short enough, such as when the requirement is simply a delivery of luggage, a telephone call can be made at a predetermined early point, even before arriving at the previous destination. It is possible to make a call in various modes, for example, the execution unit performs a telephone call operation.

At this time, from the telephone output voice data pre-recorded in the telephone output voice memory 54, an appropriate one at that time is selected by the automatic telephone output voice selection section 55, and the telephone communication is executed. The contents are output to the unit 49 so that a telephone call of the content can be made at a predetermined time when the telephone call is made.

However, there are various modes for automatically making a call on a telephone currently used. In the above case, the portable telephone automatically outputs the voice of the content based on data inputted from the outside. It is premised that a mobile phone that does not have such a function can be used. When a mobile phone that does not have such a function is used, when the telephone communication is performed by the telephone communication execution unit 49, the signal for the automatic telephone output is used. The data of the selection unit 55 is output to the voice synthesis unit 61, and the voice is output from the speaker 63 through the voice output unit 62,
It can also be set to output to a mobile phone as audio. FIG. 1 shows one that can perform both of the above functions.

Various means can be used as means for outputting predetermined contents of voice from the mobile phone 47. For example, when the mobile phone 47 has a voice output memory, the memory of the user is stored in the memory. Various voices may be input in advance, and at the time of the voice communication as described above, voices having predetermined contents may be selected from the voices and output according to an instruction from the communication unit 48. At this time, the telephone output audio memory 54 is used in the functional block shown in FIG.
It is also possible to modify the block configuration as appropriate, such as by deleting

By the automatic telephone function as described above, at the appropriate time, the next destination, which is automatically set in the guide route,
Although it is possible to make a telephone call of a predetermined content, it is necessary to change the subsequent response of the user side variously depending on the response state of the other party when the telephone call is made. For example, when the user is a delivery center person and is trying to deliver goods to a visit, the place where the call is made is not answered even if the call rings 20 times, or the answering machine is When the message flows, the house is determined to be away, and a new guidance route calculation process with the visited place postponed is performed.

At this time, the telephone answer analysis unit 57 counts the number of ringing tones and determines that the ringing sound is 20 times or more, and determines that the sound is a voice signal when the sound is transmitted from the answering machine as described above. Voice recognition unit 5
The voice recognition section 58 outputs the signal to the voice recognition section 58 and determines from the voice signal that the message is an answering machine message.
It is preferable that the voice recognition unit 58 use a voice recognition unit 45 for recognizing voice from the microphone 44 connected to the navigation control device 10 in terms of effective use of the circuit.

Further, in the telephone response analysis section 57, when the other party answers the telephone at home when the telephone call is made in the telephone communication execution section 49 as described above, the telephone output voice memory 54 stores it in advance. For example, "This is @Delivery Center. Thank you for coming to your house. Thank you. Since this phone is an automatic phone, there is no need to answer." Select and send such voice. As a result, it is understood that the person who answered the call has a person who is about to deliver the goods, that it is better not to be away for a while, and that it is not necessary to answer the call, Useless responses to the machine can be prevented from being offended.

As described above, when a telephone call is made by the telephone communication execution unit 49, a message of an answering machine flows from the other party, and when the voice recognition unit 58 recognizes this message and detects that it is an answering machine, an automatic telephone call is made. Output audio selector 55
From the telephone output voice memory 54, for example, "This is the @ delivery center. I was going to visit your house from now on, but it looks like I'm away, so I'll call again later. Thank you very much. "
Message can be output after the "peep" sound at the start of answering machine input.

In the above case, if necessary, the situation of the response from the other party after making a call from the navigation device is converted into data, and the speech synthesis unit 61 and the speech output unit 6 are used.
For example, a voice output such as "I'm away, so I'll guide you through a new route." If necessary, the data is output to the screen synthesizing unit 27, and the above-mentioned contents are displayed on the screen. Even if there is no user near this apparatus, the destination to be visited as a result of telephone communication is absent. Thus, it can be notified that a new guidance route has been set.

In the navigation control device 10 having the functional blocks as described above, the processing of the automatic visiting order change unit 60 can be sequentially performed by, for example, an operation flow as shown in FIG. This will be described with reference to the functional block diagram of FIG.

In the automatic order changing process shown in FIG. 2, the user first inputs a destination to be visited sequentially by car (step S1). At this time, it is necessary to enter a telephone number to call each visit, but when the navigation device has a point search function by telephone number input as described above, the telephone number is entered from the beginning. This is convenient because it is possible to end the input of all the visit destinations only with the help of the user.

Next, the navigation control device 10 calculates and outputs the most appropriate guidance route for sequentially visiting these inputted destinations (step S2). The calculation of the guide route can be performed in the guide route calculation unit 30 in FIG. 1 in exactly the same way as the conventional means for setting the waypoint and destination by the navigation device and calculating the optimal guide route.

It is not always necessary to perform the input of the visiting place and the calculation output of the guide route immediately before the departure. For example, in order to schedule the work on the next day, these inputs are made in advance on the previous day, and After performing the above-mentioned calculation output, taking into account that input work etc. is performed considerably earlier than at the time of departure for work etc. to grasp whether there is an inappropriate action plan It is determined whether or not the vehicle really departs from the user by inputting an operation start signal or the like (step S3).

By detecting the input of the signal as described above,
When it is determined that the user is about to leave, a call is first made to a destination to be visited (step S).
4). This is because the telephone contact selection unit 52 of FIG. 1 fetches the telephone number corresponding to the destination to be visited in the guidance route memory 31 from the telephone number memory 53, and the telephone destination is determined. The mobile phone 47 is instructed via 48 to make a call to the determined destination.

After the call is made, the ringing tone of the other party's phone is analyzed, and whether or not the ringing tone has sounded a predetermined number of times or more, whether or not an answering machine message has flowed, and whether or not the other party has answered the phone call Is detected (step S
5). As a result, when the other party does not answer the phone even if the ringing tone sounds more than a predetermined number of times, or when it is detected that an answering machine message has flowed, it is determined that the destination to be visited in the future is under answering (step S6) At that time, while considering that this visit will be postponed,
A new guidance route that becomes the most appropriate route as a whole is calculated and output (step S9). Thereafter, the process returns to the step S4, calls the destination to be visited along the newly calculated guidance route, and repeats the above operation.

In step S6, when it is determined that the destination to be visited is not away, for example, when it is detected that the other party has answered the call from here, the user of this vehicle Starts running along the presented guidance route (step S7). afterwards,
It is determined whether there are any more visits besides the visits to be decided which have already been decided (step S8). As a result of the determination, when it is determined that there is still a visit destination, it is determined whether it is time to call the next scheduled visit destination (step S10).

The time for telephone call to the next scheduled visit destination can be arbitrarily set according to various modes as described above.
For example, when it is detected that the user has left the vehicle and returned to the vehicle for a visit to one destination, for example, by operating a key switch of the engine, or from the vehicle to arrive at the destination and perform work or the like. An appropriate time can be set, for example, when it is detected that the user has got off, or when the user has not yet got off the car shortly before arriving at the previous destination. If it is determined that it is not the set time yet, this operation is repeated until this is determined. When it is determined that the telephone communication time has come, the procedure returns to the step S4, and a call is made to a destination to be visited, and the above operation is repeated.

The above operation is repeated, and step S8
When it is determined that there is no next visit destination, that is, when it is determined that the visits to all the visit destinations have been completed, this process ends (step S11).

As a result of performing the above-described operation, in the present invention, for example, in the case of going from the current position of the point P shown in FIG. At first, when no condition is given to the order of the visits, the guidance route calculation unit performs the operations shown in FIG.
Are calculated and presented.

When the user travels along the guidance route presented to the navigation device in such a state, if the conventional navigation device is used, for example, the person at the visited home at the point B If the user is already away from the point of departure around the destination of A, the user who has left point A without knowing that will arrive at the destination of point B and will know that he is away. In such a case, the user, as shown in FIG.
After completing the requirements such as the delivery of goods at this destination, return to the destination at point B, and if the destination at point B was at home at this time, complete the requirements there. Travels along a preset guidance route. At that time, a new guide route is calculated by newly calculating an optimal route to return to the point P, which is the departure point, via the destination of the point D, which is a visit destination that has not been visited at that time. In this case, the vehicle will travel to the point D along a new guidance route. Note that the example shown in FIG. 5 shows a state where the initially presented guidance route and the newly calculated and presented guidance route are the same. In the above-described conventional method, the vehicle travels between the point B and the point C in an overlapping manner as shown in FIG. 5, so that the traveling distance increases and the required time increases.

In the above example, when the visit at the point B is out of the office, after completing the requirements at the point C, the user returns to the visit at the point B. At this time, the visit at the point B is at home However, when the conventional navigation device is used, when the visit destination of the point B is absent as described above, when the visit destination of the last visit point D is to be visited. After completing the requirements, the user often returns to the visited place of the point B. In this case, the vehicle travels along the route as shown in FIG. 6, and as shown in FIG. 6, the vehicle travels more than the first guidance route because of the overlap between the point A and the point B, and the travel distance increases by that much. And the required time will also increase.

In the example shown in FIG.
Returning to the point B immediately after completing the requirements in the above, an example is shown in which the visiting place of the point B was at home at that time. The traveling distance for the overlap traveling between the point A and the point B is increased, and more time is required.

On the other hand, in the present invention, as shown in FIG. 7, after starting from the point P and visiting the point A, the navigation device calls the destination of the point B, and as a result, it is found that the user is away. As a result of the calculation of the guidance route that immediately postpone the point B, the calculation output of a new guidance route that turns in the order of the points D, C, and B is output. This route is almost the same as the guide route calculated at the start of departure in terms of the distance, and it can be seen that an effective guide route was presented.

FIG. 8 schematically shows the route to see the outline of the length of the guide route, and FIG. 8A shows the route P- indicated by the bold line based on the guide route calculated at the start of departure.
For ABCD, as shown in FIG. 7, a route P-A- indicated by a dashed-dotted line with a newly calculated guidance route is output.
Comparing with DCBP, it turns out that the distance does not change. On the other hand, in the conventional case of FIG. 6, for example, as shown by a broken line in FIG. 6B, the vehicle travels a longer distance than the original route by reciprocating between points A and B. , One side of the illustrated cell is 1
In this case, the vehicle must travel 18 lengths compared to 12 lengths on the initial route, which results in a 50% longer traveling distance. In this regard, in the present invention, as described above, it can be seen that the length of the route is initially the same as that of the route and is effective.

In the above embodiment, an example in which a mobile phone is used as a means for making a call to a visit destination has been described. However, other means such as a car phone provided in a vehicle can be used.

[0058]

The present invention is configured as described above.
When using a route guidance function provided by a navigation device equipped with an external communication function to visit a number of destinations by car in turn, automatically know that the destination to be visited is out of the office In this way, when it is determined that the user is away, the previously set guidance route is automatically changed and presented. As a result, the travel route can be shortened as a result, and the time for visiting all the visited places can be shortened.

When the telephone number is recorded on a data recording medium attached to the navigation device, when the telephone number required to call a destination to be visited from now on is input, the telephone number is automatically entered. The point corresponding to the telephone number can be specified and registered, the use of the present invention is facilitated, and the telephone number recorded on the data recording medium can be effectively used for a new use.
