Communicate between communicator 310 and the communicator 110 of above-mentioned navigating instrument 100 and between the communicator 210 of portable set 200.Communicator 310, by the communication between the communicator 110 of navigating instrument 100, receives automobile path data, destination data and mobile unit ID etc., and sends the multimodal transport path data explored to by control device 11 or track search is made a summary.In addition, communicator 310, by the communication between the communicator 210 of portable set 200, sends multimodal transport path data etc.

Operation information database 320 stores between the operation information of each means of transportation in public transit facility, each means of transportation with being associated.This operation information comprise each means of transportation time information (time information that sets out, due in information), postpone and run the relevant information etc. such as to stop to running.In addition, the time information of each means of transportation, can obtain from the timing that each means of transportation there occurs renewal (such as the amendment time of running).In addition, the postponing, runs the relevant information such as to stop to running of each means of transportation, can obtain from each means of transportation by per stipulated time or creating the timing that operation delay or operation stop.

The traffic congestion information such as the traffic jam degree of each road and each road or link hourage store by traffic congestion information database 330 with being associated.In addition, the traffic congestion information such as this traffic jam degree and link hourage, was updated according to per stipulated time.In addition, the traffic congestion information such as traffic jam degree and link hourage, such as can obtain from VICS (registered trademark) center, or generate based on the information obtained from probe vehicles (Floating Car (floating car)).

Map information database 340 is identical with the map data base that above-mentioned navigating instrument 100 carries, detailed.

The parking lot information in each parking lot and each parking lot (such as situation (having vacant position or full car), Parking Fee, the car body size etc. that can stop) stores by parking lot information database 350 with being associated.In addition, the parking lot information in each parking lot can obtain from each parking lot according to per stipulated time.

In addition, when control device 360 pairs of multimodal transport paths are explored, synthetically explore from utilized means of transportation, by bus station (or bus stop, airport, harbour) near parking lot, play parking lot from departure place (current location) till path, to play from parking lot station by bus (or bus stop, airport, harbour) till path, from alighting stop (or bus stop, airport, harbour) play destination till path etc., play destination from departure place till path.Such as, when the automobile path data received, destination data represent departure place A and destination B, automatically explore as departure place (current location) → parking lot P (mobile means: automobile), P → A station, parking lot (mobile means: on foot), A station → B station (mobile means: train), B station → destination G (mobile means: the path on foot).In addition, utilize interval to be on foot the interval not utilizing public transport means, also comprising bicycle etc. can the situation of means of at random movement.

Further, when control device 360 pairs of multimodal transport paths at center 300 are explored, the multimodal transport path of the shortest regulation number (such as 3) of required time till playing destination from departure place is explored.Then, the automobile path received and the multimodal transport path explored compare by control device 360, judge path (multilevel iudge portion) more preferably among automobile path and multimodal transport path.In other words, judge whether to exist than multimodal transport path more preferably, automobile path.In addition, whether judgement more preferably carries out according to the required time (expecting the time) till playing destination from departure place in automobile path from the required time (expecting the time) till destination is played in departure place and multimodal transport path.That is, when comparing automobile path and multimodal transport path as described above, the required time in automobile path and the required time in multimodal transport path are compared.Then, the shorter side of required time is judged as more preferably.

At this, the process action of process flow diagram to the route guidance system of present embodiment based on Fig. 5 is described.In addition, step S10 ~ the S18 of the process flow diagram of Fig. 5 is the process in navigating instrument 100, and this process is performed when inputting departure place information, destination information and represent the operation signal that the exploration in the automobile path till playing destination from departure place indicates or receive the routing summary etc. sent from center 300.On the other hand, the process centered by the step S20 ~ S25 of the process flow diagram of Fig. 5 in 300, this process is performed when the request receiving automobile path data or the multimodal transport path sent from navigating instrument 100.

In step slo, the control device 180 of navigating instrument 100, based on the departure place information exported from operating switch 160 and destination information, the departure place in setting automobile path and destination (configuration part).

In step s 11, the control device 180 of navigating instrument 100 is used in the data stored in map data base 120, explores the automobile path (automobile track search portion) till playing destination from departure place.In the exploration in this automobile path, such as explore known recommendation paths, 5 routes (as an example for recommending, charge preferential, normal precedence, distance priority, other routes) etc.

In step s 12, the control device 180 of navigating instrument 100 uses communicator 110, by comprise the automobile path explored in step S11 automobile path data, represent that the information relevant to the automobile path till playing destination from departure place of the destination data (that is, representing in step S10 the data of the destination set) of the destination in this automobile path sends to center 300 (mobile unit side Department of Communication Force) together with mobile unit ID.

At this, enter the process of side, center 300.In step S20, if be have received the automobile path data, destination data and the mobile unit ID that send from navigating instrument 100 (communicator 110) by communicator 310, then multimodal transport path explored by the control device 360 at center 300.Namely, the control device 360 at center 300 is based on automobile path data and destination data, use operation information database 320, traffic congestion information database 330, map information database 340 and parking lot information database 350, explore set in step S10 play destination from departure place till multimodal transport path (multimodal transport track search portion).In addition, if having received automobile path data, destination data and mobile unit ID by communicator 310, then this automobile path data, destination data and mobile unit ID are stored into HDD etc. with being associated by the control device 360 at center 300.

In the step s 21, the control device 360 at center 300 judges that whether multimodal transport path is more Zao than automobile path and arrives destination.Namely, the control device 360 at center 300 in the automobile path received from the required time till destination is played in departure place with the multimodal transport path explored play destination from departure place required time compare, judge whether to exist the multimodal transport path (multilevel iudge portion) than automobile path more preferably (required time is shorter).In other words, the control device 360 at center 300 in the automobile path received from the required time till destination is played in departure place with the multimodal transport path explored play destination from departure place required time compare, judge path (multilevel iudge portion) more preferably among automobile path and multimodal transport path.Then, when being judged as existing than multimodal transport path more preferably, automobile path, be considered as multimodal transport path and enter step S22 than more Zao arrival destination, automobile path, when being judged as not existing than multimodal transport path more preferably, automobile path, being considered as automobile path and entering step S24 than more Zao arrival destination, multimodal transport path.

In step S22, the control device 360 at center 300 makes the information representing and exist than multimodal transport path more preferably, automobile path.That is, the control device 360 at center 300, when being judged as that multimodal transport path than automobile path more preferably, makes the information representing and exist than multimodal transport path more preferably, automobile path.

In the present embodiment, as representing the information existed than multimodal transport path more preferably, automobile path, adopt the information (i.e. routing summary) representing the summary (summary) in multimodal transport path and the summary (summary) in automobile path.That is, the control device 360 at center 300 makes routing summary.

In addition, this expression exists than the information in multimodal transport path more preferably, automobile path, is to be different from the multimodal transport path data that shows multimodal transport path in the display frame in display device 150.As described above, be the summary (summary) in multimodal transport path and the summary (summary) in automobile path, data volume is fully less than multimodal transport path data for this information.

In step S23, the control device 360 at center 300 uses communicator 310, the routing summary guide made boat instrument 100 is sent (central side Department of Communication Force) in step S22.Namely, the control device 360 at center 300, when being judged as that multimodal transport path than automobile path more preferably, using communicator 310 first expression to be existed and sending (central side Department of Communication Force) than information (routing summary) the navigation instrument 100 in multimodal transport path more preferably, automobile path.Thus, the route guidance system of present embodiment, even if when being judged as that multimodal transport path than automobile path more preferably, also can not send data (multimodal transport path data) the navigation instrument 100 in multimodal transport path immediately.

In addition, in the exploration in multimodal transport path, explore to the path of automobile (taxi, motorbus etc.) as mobile means only using public transit facility sometimes.That is, sometimes may explore than the automobile path explored to by navigating instrument 100 more preferably, as multimodal transport path only using the path of automobile as mobile means.Such as, this is likely produce owing to exploring the data used different (newness degree is different) in navigating instrument 100 with center 300.That is, be likely that the data of including due to map data base 120 are different with the data that map information database 340 is included and produce.In addition, be likely can to travel on bus lane road and private home vehicle and company's car can not travel and produce on bus lane road due to the motorbus of the automobile as public transit facility.

But motorbus, taxi are not so good as private home vehicle, company's car in transportation expenses.In addition, get off from the automobile taken (private home vehicle, company's car) and change to motorbus or taxi is more loaded down with trivial details.Namely, even if when multimodal transport path (using motorbus or taxi as mobile means) is than the more Zao arrival destination, automobile path explored to by navigating instrument 100, for wanting the occupant carrying out movement with automobile (private home vehicle, company's car), in most cases direct carry out moving with automobile (private home vehicle, company's car) better.Namely, except except destination must be arrived before the regulation moment, change to compared with motorbus, taxi with specially getting off from the automobile of having ridden (private home vehicle, company's car), more wish directly to move with automobile (private home vehicle, company's car).

Therefore, when as multimodal transport track search to only using automobile (motorbus, taxi) as the path of mobile means, also can be judged as that the automobile path explored to by navigating instrument 100 is than this multimodal transport path more preferably.

Thus, as multimodal transport path, can suppress to report existence only using the path of automobile (motorbus, taxi) as mobile means to automobile passengers, be therefore preferred.In other words, can suppress to urge from the automobile of having ridden (private home vehicle, company's car) to motorbus, Taxi Transfer occupant, be therefore preferred.

In addition, also can be, though when as multimodal transport track search to only using automobile (motorbus, taxi) as the path of mobile means, also the communicator 110 of the summary navigation instrument 100 in this multimodal transport path is sent.

On the other hand, when being judged as that automobile path than multimodal transport path more preferably in the step s 21, in step s 24 which, the control device 360 navigation instrument 100 at center 300 notifies the situation that there is not corresponding multimodal transport path.That is, navigation instrument 100 notifies to there is not the situation than multimodal transport path more preferably, automobile path.Now, the control device 360 at center 300 uses communicator 310, and the communicator 110 of navigation instrument 100 sends the signal (information) representing and do not have corresponding multimodal transport path.

In addition, in navigating instrument 100, this expression not being existed the signal (information) in corresponding multimodal transport path, being used as a triggering (signal) for automobile path being set as path of navigation.That is, the situation not having corresponding multimodal transport path to automobile passengers's report is not used to.

Usually, carborne occupant, great majority are undertaken moving taking into automobile as prerequisite by using automobile.Therefore, there is not the situation in corresponding multimodal transport path, is in most cases unwanted information for automobile passengers.Therefore, by being arranged to not report this situation that there is not corresponding multimodal transport path to automobile passengers, can suppress for occupant's report to the unwanted information of automobile passengers, be therefore preferred.

At this, be back to the process of navigating instrument 100 side.In step s 13, the control device 180 of navigating instrument 100, the situation of the routing summary sent from center 300 is being have received (namely by communicator 110, center 300 is judged as that multimodal transport path is than automobile path situation more preferably (multilevel iudge portion)) under, this routing summary is shown in the display frame of display device 150, reports (reporting unit) by situation about existing than multimodal transport path more preferably, automobile path to automobile passengers thus.The example that this routing is made a summary has been shown in Fig. 4 (a).This Fig. 4 (a) is the schematic diagram of the summary of the routing shown by display frame of the display device 150 of navigating instrument 100.In this example embodiment, as path 1, display summary, i.e. current position → A station (mobile means: car) in first multimodal transport path, A station → B station (mobile means: the train of railroad J), B station → destination (mobile means: on foot) and required time (in this case 45 minutes).In addition, as path 2, display summary, i.e. current position → A station (mobile means: car) in second multimodal transport path, A station → B station (mobile means: the train of railroad M), B station → destination (mobile means: on foot) and required time (in this case 55 minutes points).Then, as path 3, the summary in display automobile path, i.e. required time (in this case 90 minutes).Thus, routing summary also can according to required time from being short to long order to show multimodal transport path and automobile path.

In step S14, the control device 180 of navigating instrument 100, based on the signal exported from operating switch 160, judges whether to have selected multimodal transport path in the routing summary reported from step S13.

Such as, when have employed touch panel as operating switch 160, under the state showing routing summary as Fig. 4 (a), represent the signal at the position touching display multimodal transport path if output, be then judged as have selected multimodal transport path.Represent the signal at the position touching this multimodal transport path of display, the signal representing request multimodal transport path can be made by antonomasia.In addition, equally, under the state showing routing summary as Fig. 4 (a), if output the signal representing and touch the position in display automobile path, be then judged as have selected automobile path.In addition, as shown in Fig. 4 (a), the display format in selected path also can be made to change.In this example embodiment, the situation that have selected path 1 is shown.

In addition, also can be that the control device 180 of navigating instrument 100, under the state showing routing summary as Fig. 4 (a), when also not exporting the signal from operating switch 160 at the appointed time, is considered as have selected automobile path.That is, non-selected multimodal transport path can be also judged as.Thus, not wanting to select the occupant in multimodal transport path to operate especially (operation of operating switch 160) with regard to not needing, is therefore preferred.

Then, when being judged as entering step S15 when have selected multimodal transport path, be judged as entering step S17 in unselected situation (being such as judged as have selected the situation in automobile path).

In step S15, the control device 180 of navigating instrument 100 according to the instruction of automobile passengers (namely, according to the operation of occupant, operating switch 160 outputs the situation of the signal representing request multimodal transport path, the situation that occupant have selected multimodal transport path), use communicator 110 to provide multimodal transport path (request unit) to center 300 request.That is, the control device 180 of navigating instrument 100 is according to the instruction of automobile passengers, uses communicator 110 to represent that the request signal in request multimodal transport path sends to center 300 (communicator 310).

At this, again enter the process of side, center 300.In step s 25, if received the request (request signal) in the multimodal transport path sent from navigating instrument 100 by communicator 310, then multimodal transport path (multimodal transport path data) navigation instrument 100 is sent (issue) (central side Department of Communication Force) by the control device 360 at center 300.Thus, the route guidance system of present embodiment is when being judged as existing than multimodal transport path more preferably, automobile path, and occupant have selected multimodal transport path and just multimodal transport path data navigation instrument 100 can be sent.That is, wish when obtaining multimodal transport path, multimodal transport path data navigation instrument 100 to be sent automobile passengers.

In addition, as this multimodal transport path data, except path data (automobile path, the path that have selected interval on foot as mobile means i.e. path on foot, the path and public transit facility path etc. in the interval of public transit facility is have selected as mobile means) beyond, by bus station (or the bus stop comprised in selected multimodal transport path can also be comprised, airport, harbour) timetable, the expense of public transit facility, the expense in parking lot, the required time in the interval of movement is carried out with public transit facility, to carry out the data such as the required time in the interval of movement on foot.

Then, the process of navigating instrument 100 side is again back to.If received the multimodal transport path data sent from center 300 (communicator 310) by communicator 110, then enter step S16.In step s 16, multimodal transport path setting is path of navigation by the control device 180 of navigating instrument 100.Then, in step S18, multimodal transport path, by being shown in the display frame of display device 150 in multimodal transport path based on the multimodal transport path data received, provides (path providing unit) to automobile passengers by the control device 180 of navigating instrument 100 thus.In addition, when multimodal transport path is provided to occupant, preferably also together provide above-mentioned station by bus (or bus stop, airport, harbour) timetable, the expense of public transit facility, parking lot expense, carry out with public transit facility the interval of movement required time and with the required time etc. in the interval of carrying out movement on foot.

An example in this multimodal transport path represents in Fig. 4 (b).This Fig. 4 (b) is the schematic diagram in multimodal transport path shown in the display frame of the display device 150 of navigating instrument 100.In this example embodiment, the road played from current position till A station (mobile means: car) is shown with the form (such as making thickness, color difference) different from other roads, the circuit played from A station till B station (mobile means: the train of railroad J) is shown with the form (such as making thickness, color difference) different from other lines, destination (mobile means: the road on foot) shows with the form (such as making thickness, color difference) different from other lines will be played from B station.Thus, once the All Paths (multimodal transport path) till playing destination from departure place is guided (providing), carry out to operating switch 160 troublesome operation that operates etc. in order to show paths when not needing thus to switch mobile means, be therefore preferred at every turn.

In addition, also can be that this multimodal transport path data is sent to portable set 200 by from center 300.Then, the control device 260 of portable set 200, by being shown in the display frame of display device 230 in multimodal transport path based on the multimodal transport path data received, provides multimodal transport path (portable set side path providing unit) thus.Thus, even if after occupant gets off from automobile, also multimodal transport path can be provided to occupant.In addition, by sending multimodal transport path from center 300 to portable set 200 like this, have no progeny even if close at the IG (ignition switch) of automobile or ACC (annex switch), also can send multimodal transport path to portable set 200, be therefore preferred.But, also can be that this multimodal transport path data is sent to portable set 200 by from navigating instrument 100.

On the other hand, in step S14 when the non-selected multimodal transport path of occupant and be judged as not existing in the multilevel iudge of side, center 300 than multimodal transport path more preferably, automobile path situation (namely, be judged as that automobile path is than multimodal transport path situation more preferably) under, enter step S17.In step S17, automobile path is set as path of navigation by the control device 180 of navigating instrument 100.Then, in step S18, the control device 180 of navigating instrument 100 is shown in the display frame of display device 150 by the automobile path self explored to, radial for motor road automobile passengers is provided (path providing unit) thus.Such as carry out as follows: in the display frame of display device 150, the automobile path that should travel is shown by overlapping road-map Shangdi from truck position (representing the marking of cars of the current location of vehicle), and when arriving regulation point from truck position, exported by voice output 170 and guide sound.

Thus, automobile path and multimodal transport path are being compared, and automobile path than multimodal transport path more preferably when, radial for motor road automobile passengers is provided, can the automobile path till playing destination from departure place be guided thus.In addition, even if multimodal transport path than automobile path more preferably, when not asking the providing of multimodal transport path, when namely automobile passengers does not wish providing of multimodal transport path, radial for motor road automobile passengers is provided, can the automobile path till playing destination from departure place be guided thus.

On the other hand, when multimodal transport path than automobile path more preferably, first by existence report to automobile passengers than the situation in multimodal transport path more preferably, automobile path.Then, when the situation about providing, the i.e. automobile passengers that request multimodal transport path wish providing of multimodal transport path, multimodal transport path is provided to automobile passengers, can the multimodal transport path till playing destination from departure place be guided thus.Thereby, it is possible to guide meeting the free routing that user wishes among automobile path and multimodal transport path.

Namely, the prerequisite of route guidance system of the present invention is to occupant's steer motor path, but when existing than multimodal transport path more preferably, automobile path and automobile passengers wishes providing of multimodal transport path, multimodal transport path is guided.

Thus, when being judged as that multimodal transport path than automobile path more preferably, first center 300 will represent that the information guide boat instrument 100 existed than multimodal transport path more preferably, automobile path sends.Then, if there is the request in the multimodal transport path from navigating instrument 100, then multimodal transport path data navigation instrument 100 is sent.Therefore, when multimodal transport path than automobile path more preferably, and send compared with multimodal transport path immediately, the traffic of center 300 and navigating instrument 100 can be reduced.

In addition, in the present embodiment, to represent that the information (Route guiding summary) of the summary in multimodal transport path and the summary in automobile path sends from center 300 navigation instrument 100, and show in the display device 150 of navigating instrument 100, situation about existing than multimodal transport path more preferably, automobile path can be reported thus.

And, as Route guiding summary, adopt the summary in the multimodal transport path only mobile means and the starting and terminal point (switching the place of mobile means in addition as required) of mobile means and the required time till playing destination from departure place are included, and the summary in the automobile the path only required time till playing destination from departure place is included, thus with as Route guiding by summary in addition to such information also by the by bus station in multimodal transport path (or bus stop, airport, harbour) the situation about being included such as timetable compare, the traffic of center 300 and navigating instrument 100 can be reduced.

In addition, the route guidance system of present embodiment, as described above, explores multimodal transport path by center 300, therefore, it is possible to suppress the load of navigating instrument 100 to increase, and can be provided to occupant in multimodal transport path as required.That is, do not need to explore multimodal transport path in navigating instrument 100, therefore, it is possible to suppress the load of navigating instrument 100 to increase.Therefore, navigating instrument 100 also can not have the function exploring multimodal transport path, does not also need the operation conditions etc. storing or obtain from outside each means of transportation that public transit facility comprises.And, hold the user of the navigating instrument only can exploring automobile path, as long as radio communication can be carried out with navigating instrument, center, so do not need newly to buy the navigating instrument can explored automobile path and multimodal transport path, just can accept the guiding in multimodal transport path as required.

(the second embodiment)

Next, the route guidance system of the second embodiment is described.

Second embodiment and the common part of above-mentioned embodiment more, therefore omit the description common part, emphasis is described difference.Second embodiment to the difference of above-mentioned embodiment is: as with play destination from departure place till the relevant information in automobile path have employed departure place data and destination data this point, explored automobile path this point by center 300 and radial for the motor road explored to by this center 300 navigating instrument 100 is sent this point.In addition, the structure of route guidance system is identical with above-mentioned embodiment, therefore omits the description.In addition, in the process flow diagram shown in Fig. 6, for the process flow diagram something in common shown in Fig. 5, give identical number of steps and omit the description.

At this, the process action of process flow diagram to the route guidance system of present embodiment based on Fig. 6 is described.In addition, step S10, the S13 ~ S18 of the process flow diagram of Fig. 6, S30, S31 are the process in navigating instrument 100, and this process is performed when inputting departure place information, destination information and represent the operation signal that the exploration in the automobile path till playing destination from departure place indicates or receive the routing summary etc. sent from center 300.On the other hand, the step S40 of the process flow diagram of Fig. 6, S20 ~ S23, S25, S41 are the process in center 300, and this process is performed when receiving the departure place data etc. sent from navigating instrument 100.
