Guidance information at present embodiment provides in the system 1; Guider 2 can and information center 3 between communicate guidance informations such as obtaining (reception) transport information; The pilot point G of regulation (from than pilot point G more near during till the crossing that passes through pilot point G from the demonstration starting point V of vehicle side (with reference to Fig. 3, Fig. 5) etc.), guidance information is presented on the display device 7.At this moment, of the Action Specification (flowchart text) of back, communicating by letter between guider 2 and the information center 3 carried out according to the following steps.

That is, in the present embodiment, at first, the control device 4 of guider 2 keeps watch on whether to have arrived from the car position being arranged on than showing starting point V more near the communication point C from the regulation of vehicle side predetermined distance all the time shown in Fig. 2, Fig. 3, Fig. 5 etc.And, when having arrived the communication point C of regulation, sending the session request signal through 5 pairs of information centers of said communicator 3, this session request signal is used to ask the transmission of dialog information.In the present embodiment; Method as the communication point C that judges whether to have arrived said regulation; Of Fig. 3; When getting into communication point C in respect to the direct of travel H of the road scope with angle ± 30 ° from the car position is under the situation in the circle of radius centered r (for example 50m), is judged as and has arrived communication point C.

The control part 16 of information center 3 then generates dialog information if receive the session request signal from guider 2, and guider 2 is sent this dialog information.At this moment, control part 16 is stored the guidance information that should issue respectively according to each pilot point, and updated at any time as required.Said dialog information is the dialogue screen D (with reference to Fig. 2 (b)) that is used to show the issue of the guidance information that is used to select whether to accept pilot point G basically.On the dialogue screen D, comprise the selector button (project of setting on the touch panel) of " being (YES) ", " not (NO) ".

At this moment, control part 16 makes the information of the content that comprises the guidance information that is illustrated in the issue of this pilot point G place in the dialog information that must send.Specifically, in the dialog information display frame shown in Fig. 2 (b), according to the content of guidance information, data representing is as " carrying out the guiding of city super expressway.", " carry out the guiding of the inlet lamp in the place ahead.", " carry out the guiding of the crossing in the place ahead." in the message of content of such guidance information at least certain.Then, meanwhile, control part 16 judges whether the content as the guidance information that should provide exists traffic jam information, makes to comprise information that expression traffic jam information the has or not, " information that traffic jam is arranged for example." or " no traffic jam." message.

The control device 4 of guider 2 is if receive dialog information from information center 3, the dialog information that then receives to user notification immediately.The notice of dialog information is at this moment carried out through the both sides of the demonstration of display device 7 and the voice output of voice output 9 (reading aloud of message).In this case, after the notice of dialog information (demonstration) is carried out certain hour (for example 10 seconds), finish automatically.

User (driver of vehicle) accepts the notice of dialog information, judges whether to receive guidance information (whether accepting service), operating operation switches set 8 (touch panel) and carry out selection operation to whether receiving guidance information.The user is expecting under the situation of guidance information, and " being (YES) " carried out selection operation.If being judged as does not need guidance information, then " not (NO) " carried out selection operation and get final product.In addition; In the present embodiment; Though under by the state of any one operation of having notified dialog information but not carry out " being (YES) ", " not (NO) ", under the situation of having passed through certain time interval T (for example 10 seconds), forbid the transmission of guidance information request signal.Therefore, can not accept the issue of guidance information.

Under the situation of having made the selection that receives guidance information, 4 pairs of information centers of the control device of guider 23 send the guidance information request signal.The control part 16 of information center 3 sends guidance informations when guider 2 has received the guidance information request signal to this guider 2.Like Fig. 2 (d), shown in Figure 3, the control device 4 of guider 2 is then showing that starting point V (or the moment of stipulating) is presented at this guidance information on the picture of display device 7 if receive guidance information.

Therefore, the control device 4 of guider 2 is brought into play function with communicator 5 grades as the first request signal dispensing device, the second request signal dispensing device.In addition, the control device 4 of guider 2 is brought into play function with display device 7 and voice output 9 as the dialogue notifying device.Operating switch group 8 is as selecting arrangement performance function.On the other hand, the control part 16 of information center 3 is brought into play function as the dialog information generating apparatus, and brings into play function with communicator 17 as dialog information dispensing device and guidance information dispensing device.

The effect of said structure then, is described with reference to Fig. 4～Fig. 8.The process flow diagram of Fig. 4 has represented to provide with the guidance information of present embodiment the performed processed steps of control part 16 of performed processed steps of the control device 4 of that the issue of the guidance information of system 1 is associated, guider 2 and information center 3 side by side.

At this, as shown in Figure 4 in guider 2 sides, at first in step S10, carry out from the car position Detection, in next step S11, judge the detected communication stored point C in advance that whether arrived from the car position.As shown in Figure 3, the judgement that whether has arrived this communication point C is through judging that whether detected be to carry out in the circle of radius centered r to have got into communication point C in respect to the scope of road direct of travel H with angle ± 30 ° from the car position.

Under the situation of car position no show communication point C (being " denying " among the step S11), get back to step S10, carry out from the car position Detection all the time.In addition, (be " being " among the step S11) being judged as under the car position has arrived the situation of communication point C, in step S12, information center 3 sent the session request signals.In addition, at this constantly, shown in Fig. 2 (a), show navigator picture on the picture of the display device 7 of vehicle promptly shows the current location (and direct of travel) from car with the road-map from the car periphery.

On the other hand, as shown in Figure 4, in information center 3; In step S20, receive (collection) transport information etc. from the outside; And in step S21,, come the making of channeling conduct information and the judgement that traffic jam information has or not according to each pilot point based on the information that obtains.In next step S30, keep watch on whether received session request signal all the time from vehicle (guider 2).

Then, the control part 16 of information center 3 then in step S31, sends dialog information to the guider 2 (vehicle) that has sent the session request signal if receive the session request signal (being " being " among the step S30) from guider 2.This dialog information as stated; Except the information of the selector button that is used for showing " being (YES) ", " not (NO) ", also include information (message) and the information (message) that expression traffic jam information has or not of the content of the guidance information that is illustrated in pilot point G issue.The control part 16 of information center 3 is kept watch on the request signal that whether has received guidance information in step S40 after the transmission of dialog information.

In guider 2 (control device 4), in step S13, judge whether to have received dialog information from information center 3.Under the situation that has received dialog information, (be " being " among the step S13); In step S14 based on the dialog information that receives; Shown in Fig. 2 (b), will talk with screen D and be presented on the display device 7, and for example send through voice output 9 and " to carry out the guiding of city super expressway.", " information that traffic jam is arranged." such message.

In next step S15, judge whether to have been undertaken the selection operation of " being (YES) " by the user.In showing dialogue screen D certain time interval T (for example 10 seconds), do not have under the situation of selection operation, perhaps carried out under the situation of selection operation of " not (NO) " (in step S15, being " denying ", not accepting the issue of guidance information and directly get back to step S10.In addition, after having passed through certain time interval T, finish the demonstration of the dialogue picture of display device 7, get back to original demonstration (navigation screen).

Relative therewith, under the situation of the selection operation that has carried out " being (YES) ", (in step S15, be " being "), in next step S16, information center 3 is sent the guidance information request signal.In information center's 3 sides,, then in next step S41, send dialog information to the guider 2 (vehicle) that has sent the guidance information request signal if receive guidance information request signal (in step S40, being " being ") from vehicle.Then, get back to step S20.In addition, in the communication period of above-mentioned guidance information request signal and guidance information, on the picture of the display device 7 of vehicle, for example shown in Fig. 2 (c), show and " obtaining information." message.

In guider 2 (control device 4), in step S17, judge whether to have received guidance information.If received guidance information (in step S17, being " being "), then in step S18, shown in Fig. 2 (d), showing that starting point V is presented at guidance information on the display device 7.If passed through pilot point G, then finish the demonstration of the guidance information of display device 7, repeat the processing that begins from step S10.

Fig. 3 has represented the example of the action that the effluxion of above-mentioned processing is followed, and Fig. 5 has represented the example of each point with respect to the position relation of pilot point G.Through above-mentioned processing; As shown in Figure 3, vehicle from communication point C when pilot point G goes, guider 2 (is number 1 in the triangle) in Fig. 5 when having arrived communication point C; Remote information communication for service between beginning and the information center 3; Obtain dialog information, after time T 1, show the dialogue screen D.The user carries out the selection operation of " being (YES) " behind the demonstration time T2 of dialogue screen D.Like this, carry out once more and information center 3 between the remote information communication for service, obtain guidance information (number 2 in Fig. 5 intermediate cam).

Then, guidance information is presented on the display device 7 through demonstration starting point V later (being number 3 in the triangle in Fig. 5) in time T 3.Then, for example the user recognizes guidance information in time T 4, and then judges the action (decisions such as for example, craspedodrome, right-hand bend, left-hand bend) that should take at pilot point G in time T 5.Time T 6 through after, coming steering vehicle as the crossing of pilot point G (or inlet lamp at a high speed etc.) according to judging.

Fig. 6 and Fig. 7 have represented guidance information is presented at the concrete example under the situation on the picture of display device 7, and Fig. 6 and Fig. 7 have represented to carry out the situation of main crossing guiding and the situation of carrying out the guiding of Entry to motorway lamp respectively.In this case, with two cutting apart about the picture of display device 7, with the picture on the right side navigation screen as the current location P of expression vehicle, the picture in the left side with guidance information shows through simple map.In the example of Fig. 6,, then show the main crossing in direct of travel the place ahead and and connect the main roads of these crossings with simple map if the current location P of vehicle is near the crossing (A place) as the regulation of pilot point G.

The color of the arrow that at this moment, the having or not of each interval traffic jam of road (traffic jam degree) can be through the expression direct of travel shows.For example; With the interval of no traffic jam show with green (in the drawings for conveniently being expressed as solid line), the interval that traffic jam is less shows, will have the interval of traffic jam to show with redness (in the drawings for conveniently being expressed as dotted line) with yellow (in the drawings for conveniently being expressed as the single-point line), change color like this and show.The user for example can select, and the less road of traffic jam comes steering vehicle.

In the example of Fig. 7, under the parallel situation of super expressway and Ordinary Rd, if the current location P of vehicle is near the high speed road inlet (outlet) as pilot point G, then with the guiding of the inlet (outlet) of the super expressway in simple map demonstration direct of travel the place ahead.Also be in this case, the having or not of the traffic jam that each of road is interval (traffic jam degree) similarly the color of the arrow through the expression direct of travel show.The user can avoid the Ordinary Rd of traffic jam and get into the super expressway of no traffic jam; Perhaps avoid taking place traffic jam super expressway the interval and be driven out to the such selection of Ordinary Rd; In addition; Shown in Fig. 2 (d), also can be used as guidance information, show the guiding figure in the branch branch road of super expressway on the whole at the picture of display device 7.The color (for example red) that in this case, also can change road shows the interval of traffic jam.
