Abstract

PROBLEM TO BE SOLVED: To provide a navigation system which can navigate a user well even on a moving course where a moving section utilizing an automobile (my car) is mixed with a moving section utilizing means of traffic. SOLUTION: When a moving course calculated while taking account of the utilization of a public means of traffic includes a moving section by vehicle (S41: YES), a charge required for movement is calculated by acquiring the unit price of gasoline and the parking charge newly (S42-S47). When the moving course includes a moving section by a public means of traffic (S51: YES), a charge required for movement is calculated while taking account of a party-trip reduction (S52, S53, S56). At step S55, a charge required for a person to reach a goal is calculated by summing the individual charge of a public means of traffic and a charge required for moving by a vehicle divided by the number of persons. The charged required for movement can thereby be known before start.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for calculating a travel route to a destination and guiding a user, and more particularly, a navigation device capable of calculating a travel route including a travel section using transportation. About.

[0002]

2. Description of the Related Art As a navigation device for calculating a moving route to a destination and guiding a user, position detecting means for detecting a position of the user, destination input means for inputting a destination, and the position detecting means A route calculating means for calculating a movement route from the position detected by the destination input means to the destination input by the destination input means, and a guide means for guiding a user along the movement route calculated by the route calculation means. A navigation device having the same is considered. In this type of navigation device, the current position can be detected by the position detecting means, the destination can be input by the destination inputting means, and the travel route from the current position to the destination can be calculated by the route calculating means. The guidance unit guides the user along the calculated moving route by, for example, display or voice. As a result, the user can easily reach the desired destination.

Conventionally, this type of navigation device has been mainly used for being mounted on an automobile and used as a so-called car navigation device.
It has been proposed to calculate and guide a travel route in consideration of the use of transportation such as a ship (for example, see Japanese Patent Application Laid-Open No. 10-2).
67673).

[0004]

Here, if the above-mentioned technology is combined with the technology described in Japanese Patent Application Laid-Open No. Hei 10-31418 and the personal computer software "Station Spato" (trade name: manufactured by Val Research Institute Co., Ltd.), Although it is possible to calculate the time required to reach the destination, the fee, and the like, the conventional technology can only calculate the fee when one adult travels to the destination. However, in the case of using a car and a transportation system together, the required fee hardly changes even if the number of people moving in the vehicle increases, and the required fee in the transportation system increases almost in proportion to the number of people. For this reason, when the travel route calculated by the route calculation means includes a travel section using an automobile (my car) and a travel section using transportation, an accurate fee cannot be calculated. In addition, when a traveling section using an automobile and a traveling section using a transportation system are mixed in the traveling route, the transportation system departs at a relatively accurate time while the automobiles and the like are easily affected by traffic jams and the like. Therefore, connecting may be difficult.

[0005] Therefore, the present invention provides a navigation system that can guide a user well even when a traveling section using an automobile (my car) and a traveling section using transportation are mixed in a traveling route. It was made to provide a device.

[0006]

Means for Solving the Problems and Effects of the Invention In order to achieve the above object, according to the first aspect of the present invention, when the number of people is input by the number of people input means, the route calculating means takes into account the use of transportation. For a plurality of calculated travel routes, the fee calculation means calculates a fee per person required to travel to the destination for each travel route. For example, a fee (fuel cost, parking fee, etc.) required for a traveling section using a car (my car) is divided by the number of people, and a train fee, etc. is added individually. Therefore, in the present invention, it is possible to calculate a plurality of travel routes to a destination in consideration of the use of transportation along with an accurate fee per person.

Therefore, in the navigation apparatus according to the present invention, even if the moving section includes a moving section using a car (my car) and a moving section using transportation, the charge per person is accurately calculated. can do. Therefore, it is possible to prevent the user from running out of money or need to carry more money than necessary while traveling, and to guide the user to the destination satisfactorily.

In general transportation, there are rules for group discounts and rules for discounts for infants, children, students, elderly people, and the like. In the case of a railway, there may be a rule for discount depending on whether or not to use only ordinary trains, whether or not to combine with other transportation means (for example, a rental car) or the like. Therefore, according to the second aspect of the present invention, when there is a moving section using a transportation in a moving route, the fee calculating means calculates the fee in consideration of the discounted fee of the transportation.
For this reason, in the present invention, in addition to the effect of the invention described in claim 1, there is an effect that the fee per person can be calculated more accurately.

[0009] There are cases where regional disparities in parking fees and fuel costs cannot be ignored. In particular, the fuel cost fluctuates greatly depending on the social situation, and the parking fee fluctuates greatly depending on the travel period. Therefore, according to the third aspect of the invention, when there is a moving section by a vehicle in the moving route, the fee calculating means newly acquires information related to a parking fee or a fuel cost in calculating the fee, and acquires the information. Calculate the fee by taking this into account. For this reason, in the present invention, in addition to the effect of the first or second aspect of the present invention, there is an effect that the fee per person can be calculated more accurately.

[0010] The form in which the fee calculating means obtains the above information may be VICS (Vehicle Information and Com- munication).
munication system), information transmitted from a road information center provided in correspondence with the Internet, and information transmitted via the Internet via communication means such as a mobile phone. Various forms such as a manual input form are conceivable.

[0011] In the invention described in claim 4, the route calculating means calculates, in addition to the above-mentioned travel route, a travel route that also takes into account walking on foot. For this reason, the variation of the movement route calculated by the route calculation means increases. Therefore, in the present invention, in addition to the effect of the invention described in any one of the first to third aspects, an effect that the range of selection of the movement route by the user is widened is generated.

In the invention described in claim 5, the required time calculating means calculates the required time required for moving to the destination for each of the moving routes calculated by the route calculating means. On the other hand, the priority condition setting means can set at least whether to give priority to the fee or the required time, and based on the setting,
The moving route selecting means selects a suitable one from the plurality of moving routes. Therefore, in the present invention, claim 1
In addition to the effects of the invention described in any one of (1) to (4), it is possible to more easily select a moving route more suitable for the user's desire from the plurality of moving routes calculated by the route calculating means. Occurs.

In the invention according to claim 6, when the guide means guides the user along a moving route including a moving section using a transportation means, the judging means determines the position based on the position detected by the position detecting means. To determine whether it will be possible to use the subsequent transportation. Then, when it is determined that it is not in time, the route calculating means executes the calculation of the moving route again. For this reason, even if the time required for some travel sections is longer than expected due to the effects of traffic congestion and it becomes difficult to make connections as scheduled, a new travel route is calculated again to search for available transportation. Etc. can be performed. Therefore, according to the present invention, even when a travel section using an automobile (my car) and a travel section using transportation are mixed in the travel route, the user cannot reach the destination because the transit cannot be performed as scheduled. It is possible to prevent the user from becoming unable to do so and to guide the user to the destination satisfactorily.

[0014] In the invention according to claim 7, when the time required for a part of the traveling section is extended more than expected due to the influence of traffic congestion and the like, it becomes difficult to make a connection as scheduled, the notification means informs the user of the fact. Notice. Then, the user causes the route calculation means to execute the calculation of the travel route again to search for a usable transportation facility in the same manner as in the invention of claim 6,
Various countermeasures such as changing the destination and the order of visiting can be performed. Therefore, in the present invention, although a slight operation by the user is required, substantially the same effects as those of the invention described in claim 6 are produced, and further, the effect that the range of choices for the user can be expanded is produced. .

[0015]

Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a functional block diagram schematically showing a configuration of a car navigation device to which the present invention is applied. The car navigation device according to the present embodiment is a so-called VICS-compatible car navigation device that can receive various data such as traffic congestion information from a road information center (not shown). Further, the car navigation device of the present embodiment is a so-called portable car navigation device that is detachable from a vehicle.

As shown in FIG. 1, the car navigation system according to the present embodiment includes a position detector 1, a map data input device 3, an operation switch group 5, a communication control unit 7, a voice output device 9, a road-to-vehicle control unit. 11, display device 13, remote control sensor 15, remote control 17, printing means 19, and control device 21
It has.

The position detector 1 includes a geomagnetic sensor 23, a gyroscope 25, a distance sensor 27, and a GPS receiver 29, and is a device for detecting the current position of the vehicle based on these various detection signals. . If the current position of the vehicle can be detected, it is not necessary to provide all of the above sensors, and it is sufficient to provide at least one of the sensors.

The map data input device 3 is composed of a DVD player, a hard disk, a CD player and the like, and stores map data corresponding to a road map. The operation switches 5 are switches attached to the left and right and up and down of the display device 13 composed of a liquid crystal display.
Various selections and instructions for various operations can be performed through the operation switch group 5.

The communication control unit 7 performs two-way communication with the FM multiplex tuner 31 that receives FM multiplex broadcasts from the road information center via the antenna 31a, and with the Internet or the road information center via the mobile phone 33. And a mobile phone control unit 35. The voice output device 9 utters a voice for navigating the driver and an explanation of a screen operation. The road-to-vehicle control unit 11 receives various data transmitted from a communication device (not shown) provided on the road via the antenna 11a. The display device 13 displays a map for navigating the driver, a destination selection screen, and the like. Remote control sensor 15 receives a radio wave transmitted from remote control 17 and detects an operation state of remote control 17. The printing unit 19 is a printer that prints a later-described itinerary and the like on roll paper or the like.

These position detectors 1 to printing means 19 are:
It is connected to the control device 21. The control device 21 uses the CP
It is constituted by a microcomputer mainly composed of U, ROM, and RAM, and controls each unit based on various commands corresponding to the operation state of the operation switch group 5, the operation state of the remote controller 17 detected via the remote control sensor 15, and the like. .
For example, the current position of the vehicle is detected via the position detector 1, and a route from the current position to the destination corresponding to the command is calculated based on the map data stored in the map data input device 3, The voice output device 9 and the display device 1 indicate the route to be followed by the vehicle and the transportation to be used.
3 is instructed to the driver via the display.

The display device 13 is a color liquid crystal display, and corresponds to the vehicle current position mark input from the position detector 1 and the map data input from the map data input device 3 according to the above processing. The road map, the destination mark, and the guidance route to the destination can be displayed in a superimposed manner. The navigation process of the control device 21 as described above is well known and will not be described in detail here.

Next, the processing executed by the control unit 21 of the car navigation device will be described with reference to the flowcharts of FIGS. FIG. 2 is a flowchart showing a main routine of a process executed by control device 21. As shown in FIG. 2, when the processing is started, the control device 21 first sends various data required for route calculation and the like to the display device 13 in S1 (S represents a step: the same applies hereinafter) to the display device 13. Display the sentence and prompt the user to enter it. That is, the user is required to input the number of people who act at the same time (in the case of using public transportation where the fee varies depending on adults, children, etc., the breakdown of the number of people), the number of vehicles used, the destination, and the date and time.

When the input process is completed, in S2, a predetermined condition setting screen is displayed on the display device 13 to allow the user to input a condition to be prioritized in calculating a route or the like. The conditions to be prioritized include, for example, the cheapest, the fastest, and not using an airplane. As described above, when the number of people, the number of vehicles, the destination, the date and time, and the condition to be prioritized are input, the route calculation processing in S3 and the S
In the fee calculation process 4, a travel route that meets these conditions and a fee required for traveling to the destination are calculated. In the following S5, the user is inquired whether or not they are satisfied with the calculation results.
If not satisfied (NO), the process is repeated from the input of the condition in S2.

Here, the details of the route calculation process in S3 and the fee calculation process in S4 will be described. FIG. 3 is a flowchart showing details of the route calculation process. As shown in FIG. 3, in this process, first, in S31, the current position is detected via the position detector 1, and then in S32, a plurality of movement routes from the current position to the destination are calculated. In this calculation, not only routes for traveling by vehicle (ie, roads) but also travel routes using public transportation such as railroads, ferryboats, and airplanes are calculated. Select multiple. In subsequent S33, the required time of each traveling route is calculated, and in S34, it is individually determined whether or not there is a traveling section using public transportation for each traveling route. Then, for a travel route using public transportation (S34: YES), S
After calculating the travel route from the end point of the public transportation at 35, the travel route not used is left unchanged (S3).
4: NO), the route calculation process ends, and the process returns to the main routine.

The calculation of the required time in S33 is as follows.
In a traveling section using a car, the same as a well-known car navigation device is performed by referring to the legal speed and traffic congestion information transmitted from a road information center or the like. This can be achieved by using the technology described in Japanese Patent No. 31418 or the above-mentioned personal computer software “Station Sport”. In addition, it is possible to consider a case where the timetable of public transportation is disrupted. As described in Japanese Patent Application Laid-Open No. H10-267673, the disorder information of the schedule can be obtained by using FM multiplex broadcasting from a road information center, data obtained via the road-to-vehicle control unit 11, and the like.

FIG. 4 is a flowchart showing details of the route calculation process from the end point shown in S35 of FIG. This processing is particularly effective when the end point is far from the destination as described below. As shown in FIG.
In this process, first, in S351, a message is displayed on the display device 13, and the moving condition from the end point to the destination is determined.
That is, the user is prompted to enter on foot or to use a rental car or taxi. In subsequent S352, it is determined whether or not the user selects walking on the basis of the input, and when the user selects walking (S352: YES), S is executed.
The travel route to the destination at 353 (that is, the walking route)
And returns to the main routine. Note that this S3
The processing of 53 is executed by expanding the search range to a walkable road in the normal movement route calculation processing in the car navigation device.

When a rental car or a taxi is used (S352: NO), a travel route to the nearest facility (a taxi stand or the like) for using the rental car or taxi is calculated and the process returns to the main routine. Here, when using a taxi, the user can reach the destination simply by telling the driver of the destination. When using a rental car, after getting on the rental car, the user may restart the car navigation device and input a destination or the like. Then, the traveling route is guided with the place where the user got on the rental car as the departure point.

After calculating the entire travel route as described above, the control device 21 executes the fee calculation process in S4.
FIG. 5 is a flowchart showing details of the fee calculation process. This fee calculation process is individually executed for the plurality of travel routes calculated in S3.

As shown in FIG. 5, when this processing is started, first in S41, a vehicle (my car)
It is determined whether or not there is a moving section to move. If there is a moving section by vehicle (S41: YES), the following S42
Detects or inputs the gasoline unit price (for example, per liter). The unit price of gasoline fluctuates according to the regional characteristics and social conditions. If the unit price can be determined based on data from FM multiplex broadcasting from the road information center or the Internet, etc., the unit price of gasoline is detected according to those data. I do. However, when sufficient data for detecting the gasoline unit price cannot be obtained, or when gasoline can be purchased cheaply due to the personal circumstances of the user, the user manually inputs the unit price using a numeric keypad or the like.

If sufficient data cannot be obtained,
The unit price may be set to use a fixed value (for example, 100 yen / L). Further, when a gas station or the like where gasoline can be purchased at a low price based on data from the Internet or the like is found, it is conceivable to incorporate the gas station into the above-mentioned travel route and provide guidance to drop in at the gas station. In S43, the gasoline cost of the entire travel route is calculated based on the gasoline unit price input in S42, the total travel distance in the travel route, and the fuel efficiency.

Subsequently, the flow shifts to S45, where a parking period is detected or inputted. The parking period may be determined uniquely in accordance with the moving route, such as when a train to and from which goes is determined and the train is parked at a station during that time, or may be arbitrarily determined by the user. Therefore, when the parking period is uniquely determined from the travel route, the parking period is detected. When the parking period can be determined arbitrarily, the user manually inputs the parking period using a numeric keypad or the like.

In S46, a parking fee (for example, per hour) is detected or inputted. The parking fee fluctuates according to the regional characteristics, the time zone, the day of the week, and the like. If the parking fee can be determined based on FM multiplex broadcasting from the road information center or data from the Internet, etc. Detect parking fees. However, if we do not have enough data to detect parking fees,
If the parking lot can be cheaply reserved due to the user's personal circumstances and the like, the user manually inputs the parking fee using a numeric keypad or the like.

In S47, based on the parking period obtained in S45 and the parking fee obtained in S46, a total parking fee required for traveling on the above-mentioned travel route is calculated. The above is the fee required in accordance with the moving section of the vehicle. Then, when these charges have been calculated, the process proceeds to S51. If there is a toll road or the like in the moving section by the vehicle, those tolls and the like are added in the processing of S42 to S47. On the other hand, when there is no moving section by the vehicle on the moving route (S41: NO), S42 is performed.
Steps S47 to S47 are skipped and the process proceeds directly to S51.

In S51, it is determined whether or not there is a moving section using public transportation in the moving route. When using public transportation (S51: YES), it is determined in S52 whether there is a discount such as a group discount. In general public transportation, there are rules for group discounts and rules for discounts for infants, children, students, elderly people, and the like.
In addition, whether or not to use only ordinary trains, whether to combine with other transportation (for example, car rental),
There are cases where there is a rule for discount depending on whether or not to purchase in return. Therefore, in S51, it is determined whether various types of discounts such as group discounts can be used based on the number of people who act simultaneously and the above-mentioned travel route.

If the discount cannot be used (S52:
NO), a charge for the use of the public transport is calculated at a normal charge in S53, and the process proceeds to S55. Also,
If the discount can be used (S52: YES), the charge for the use of public transportation is calculated at a discount rate in S56,
The process moves to S55. Note that S52, S53, S56
In the processing of (1), when the use of a taxi or a rental car is input in S351 (FIG. 4), the calculation is performed in consideration of those charges.

In S55, the charge of each individual is calculated. That is, the fee for public transportation is required for each individual except in special cases, but the fee for traveling by vehicle can be divided by the number of people who act simultaneously. Therefore, in S55, a charge per person required to travel to the destination is calculated by adding a charge for each individual relating to the use of public transportation and a fee obtained by dividing the fee relating to movement by vehicle by the number of people.

Returning to FIG. 2, the calculation of the moving route (S3) and the calculation of the fee (S4) are performed as described above, and the user is satisfied with the calculation result (any of a plurality of moving routes). Then (S5: YES), the process proceeds to S6, where a ticket reservation process for public transportation or the like necessary for the travel route selected by the user is executed, and then a route guidance process to the destination (S7) is performed. Start. In the determination of whether or not the user is satisfied in S5, the travel route and the fee calculated in S3 and S4 are displayed in the display device 13 in an order that matches the condition input in S2, and the user's selection is awaited. Further, by printing out the calculated travel route and fee through the printing unit 19, a plurality of users who act simultaneously may be able to consult and decide.

FIG. 6 is a flowchart showing details of the ticket reservation processing in S6. As shown in FIG. 6, in this processing, first, in S61, it is determined whether or not there is a moving section in which the ticket must be pre-purchased in the moving route, and if there is no such moving section, (S61). : N
O), return to the main routine as it is. If there is a moving section for which a ticket must be reserved (S
61: YES), a message or the like is displayed on the display device 13 in S62, and the user is made to input reservation conditions and the like. In the following S63, a well-known reservation request process for reserving the ticket via the Internet or the like is executed, and it is determined whether or not the reservation has been made in S64. If you can make a reservation (S6
4: YES), a well-known reservation purchase process for purchasing the ticket via the Internet or the like is executed in S65, and the process returns to the main routine of FIG.

In S64, it is determined whether tickets for all persons who act simultaneously can be reserved, and if tickets cannot be reserved even for one person (S64:
NO), and proceeds to S66. In S66, the content that could not be reserved is displayed on the display device 13, and in S67, the user is inquired whether to change the condition. If the conditions are to be changed (S67: YES), the process proceeds to S62, and the user is again asked to input the reservation conditions. By this processing, it is possible to change the conditions such as the class of the seat, whether or not the seat is a non-smoking seat, and the conditions such as the reservation of the next ticket, and make a reservation purchase of the ticket.

On the other hand, when the conditions are not changed (S67:
NO), at S68, display that no reservation is made is displayed on the display device 13, and the process returns to the main routine. In this case, the route guidance process of S7 is started in a state of waiting for cancellation. Also, in the case where the calculated travel route is abandoned, a negative determination is made in S67. In this case, the user instructs to stop the process during the subsequent route guidance process in S7, and causes the travel route to be calculated from the beginning. .

FIG. 7 is a flowchart showing details of the route guidance processing in S7. In this process, first, in S70, the moving route selected by the user is determined, and then in S71
Then, route guidance is performed based on the current position of the vehicle detected through the position detector 1. That is, the same processing as that of a known car navigation device is performed. In the following S72, a route is calculated internally, and in S73, it is determined whether there is a change in the arrival time at a station, an airport, a port, or the like. If there is no change (S73: NO), the processes of S71 and S72 are repeated to guide the user, and if there is a change in the arrival time (S73: YES), the train, airplane, ferry boat is set in S74. It is determined whether the arrival to transfer to the destination is dangerous.

The case where a negative determination is made in S74 is a case where the vehicle arrives earlier than expected. Therefore, in this case (S7
4: NO) The process proceeds to S75, in which a message indicating that there is room to arrive is displayed by a message or sound, and the process proceeds to S71. On the other hand, when the arrival is in danger (S74: YES), the danger of arrival is notified in S76 by displaying a message or sound (BEEP sound or voice). In subsequent S77, a new travel route is calculated again, a search for available transportation is performed, and the content of the change in the travel route is displayed on the display device 13. The calculation of the travel route can be executed by taking into account the means of transportation using the DRGS (dynamic route search) function of a general car navigation system.

In S78, the user is asked whether to change to the newly calculated moving route or to keep the original moving route, and in S79, the user is guided to the moving route selected in S78. In the process of S79, the routine of the route guidance process of this figure is executed again for the selected moving route, and the corresponding route guidance is performed. When the vehicle arrives at the destination or when the printing by the printing unit 19 is instructed, the route guidance processing is terminated, and the processing shown in FIG.
The processing of the main routine is also terminated.

That is, since the car navigation apparatus is portable as described above, it can be carried to the destination even when using public transportation. in this case,
When the vehicle arrives at the destination, the route guidance processing in S7 ends. When a vehicle is parked in a parking lot at a station or an airport and a car navigation device is left in the vehicle, a subsequent itinerary and a necessary map can be printed out by the printing means 19 and carried. Even when such a printout is made, the route guidance processing in S7 ends.

As described above, in the car navigation system according to the present embodiment, the fee (fuel cost, parking fee, etc.) required for the traveling section using a car (my car) is divided by the number of people, and is used for public transportation. The related train fare and the like are individually added (S55). For this reason, in the present embodiment, it is possible to calculate a plurality of travel routes to the destination in consideration of the use of public transportation, together with an accurate fee per person. Therefore, even when the travel route includes a travel section using an automobile and a travel section using public transportation, the fee per person can be accurately calculated. Therefore, it is possible to prevent the user from running out of money or need to carry more money than necessary while traveling, and to guide the user to the destination satisfactorily.

Further, in this embodiment, the ticket necessary for the use of public transportation is pre-purchased (S65), and if the reservation cannot be made, the fact is notified (S66, S68). Therefore, public transportation can be used extremely smoothly, and the user can be better guided to the destination.

Further, in the present embodiment, the fee relating to the use of public transportation is calculated in consideration of various discount fees, and in calculating the fee relating to the movement by vehicle, data relating to the parking fee and gasoline fee is newly added. And calculate it. For this reason, the charge per person can be calculated more accurately.

Further, in the present embodiment, since the travel route can be calculated in consideration of the use of walking, taxi, rental car, etc. (S351), the variation of the travel route is increased, and the range of selection by the user is widened. From among them, it is possible to select a moving route that best meets conditions such as the cheapest, the fastest, and the like (S5). For this reason, it is possible to very easily select a moving route that is very well suited to the user's wishes.

Further, in this embodiment, based on the position detected by the position detector 1, it is determined whether or not it is possible to arrive at a station or the like in time for the subsequent use of public transportation (S).
74) If the arrival is in danger, the user is informed that the arrival is dangerous and the travel route is newly calculated (S76, S77). For this reason, it is possible to prevent the destination from being unable to be reached due to the inability to connect as scheduled, and to guide the user to the destination better. In addition, the notification enables the user to take measures such as changing the destination and the order of visiting.

If public transportation is used by carrying the car navigation system according to the present embodiment, for example, a train or the like on which the user is riding is delayed due to an unexpected trouble or the like, and a subsequent transportation to the public transportation is performed. It can be predicted from the detected position that the transfer will be difficult (S74). In this embodiment, even in such a case, the travel route can be calculated again (S77), and an alternative public transportation can be searched.

As described above, the present invention has been described with reference to the specific embodiments.
Are the operation switches 5, remote control 17,
And the processing of S1 is performed by the destination input means and the number of persons input means,
The processes of S3 and S77 are performed by the route calculating unit, the audio output device 9, the display device 13, the printing unit 19, and the process of S71 are performed by the guiding unit, the process of S4 is performed by the fee calculating unit, and the process of S33 is performed by the required time calculating unit. The processing of the operation switch group 5, the remote controller 17, and the processing of S2 are determined by the priority condition setting means, the processing related to the display on the display device 13 among the processing of S5 is determined by the moving path selection means, and the processing of S73 and S74 are determined. The processing of the sound output device 9 and S76 corresponds to the notification means.

The present invention is not limited to the above-described embodiment, and can be implemented in various forms without departing from the gist of the present invention. For example, the navigation device of the present invention does not need to be portable, and need not include the printing unit 19. However, in order to receive guidance while using public transportation, it is desirable to have some printing means or be portable. If the mobile phone or the notebook computer is provided with a position detecting means such as a GPS receiver, the navigation device of the present invention can be realized by the mobile phone or the notebook computer.
