With reference to the process flow diagram of Fig. 2 A and Fig. 2 B, the control action of the control part 16 of the control device 4 of guider 2 and information center 3 is described.
At first, the control part 16 of information center 3 is shown in Fig. 2 B, if in step S1, receive the guidance information request instruction that includes speed information from guider 2, then in step S2, according to the complexity in above-mentioned speed information and introductory object place, the guiding of default storage is reported the position in beginning place and adjusted; In step S3, beginning place and guidance information are reported in adjusted this guiding sent to guider 2.
That is, in above-mentioned steps S2, adjust, make that the speed of a motor vehicle (having carried the speed of the vehicle of guider 2) is fast more, guiding is reported beginning place Ph (referring to Fig. 3) more to being offset from car current location P direction (direction of arrow A among Fig. 3).In other words, adjust, make Vehicle Speed slow more, this guiding is reported beginning place Ph and is offset to introductory object place Pt direction (direction of arrow B among Fig. 3) more.
And, in the present embodiment,, also consider the complexity in the speed of a motor vehicle, introductory object place in the lump the guiding of acquiescence being reported beginning place Ph when adjusting.
For example, when introductory object place Pt is ordinary road and is when keeping straight on (complexity is lower), under the speed of a motor vehicle is situation more than the 50km/h, beginning place Ph is reported in the guiding of acquiescence to be adjusted, make it be offset 100m (to from car current location P direction) to the front, when the speed of a motor vehicle is during greater than 30km/h and less than 50km/h, guiding is reported beginning place Ph and is remained unchanged, under the speed of a motor vehicle is situation below the 30km/h, beginning place Ph is reported in the guiding of acquiescence adjust, make and rearward be offset 100m (introductory object place Pt direction).
In addition, when introductory object place Pt is ordinary road and turns left or turn right (complexity height), under the speed of a motor vehicle is situation more than the 50km/h, beginning place Ph is reported in the guiding of acquiescence to be adjusted, make it be offset 150m (to from car current location P direction) to the front, when the speed of a motor vehicle is during greater than 30km/h and less than 50km/h, beginning place Ph is reported in the guiding of acquiescence to be adjusted, make it be offset 50m (to from car current location P direction) to the front, under the speed of a motor vehicle is situation below the 30km/h, beginning place Ph is reported in the guiding of acquiescence adjust, make it rearward be offset 50m (introductory object place Pt direction).
In addition, under the situation that is super expressway, the speed of a motor vehicle is when 80km/h is above, beginning place Ph is reported in the guiding of acquiescence adjust, make it be offset 300m (to from car current location P direction), when the speed of a motor vehicle is during greater than 50km/h and less than 80km/h to the front, guiding is reported beginning place Ph and is remained unchanged, in the speed of a motor vehicle is 50km/h when following, beginning place Ph is reported in the guiding of acquiescence adjust, and makes it rearward be offset 400m (introductory object place Pt direction).
In addition, also can be judged as sometimes and can former state keep the guiding of acquiescence to report beginning place Ph, in this case, not change.
On the other hand, the control device 4 of guider 2 is shown in Fig. 2 A, and in step T1, the communication of the storage in advance that judges whether to travel begins place Pk (referring to Fig. 3).If be judged as and travel, then in step T2, the guidance information request instruction that will include speed information sends to information center 3.
In addition, in Fig. 3,, represent from the car current location with Reference numeral P with the example that the Reference numeral Pt of Fig. 3 represents the introductory object place.
In addition, under situation about guidance information being shown on the display 7, except displayed map, also represent introductory object place Pt (referring to Fig. 3) with show tags M.In addition, represent from vehicle with show tags Ms.In addition, this Fig. 3 shows on the display 7 example that shows, reports beginning place Ph and does not show but above-mentioned communication begins place Pk and guiding.
In following step T3, judge whether under the state of not finishing from the message pick-up of information center 3, just to have crossed guiding and report beginning place Ph.Be judged as under the situation of "No", transferring to step T4, judging whether to have finished message pick-up.At this, if finished message pick-up, then in step T5, whether judgement had travelled to guide from car is reported beginning place Ph, travels if be judged as, then in step T6, make display 7 and voice output 9 work, the guidance information of obtaining is reported.
Afterwards, in step T7, passed through introductory object place Pt, then in step T8, finished guiding and report if be judged as.
In addition, begin place Ph (being "Yes") in step T3, then in step T9, reporting of guidance information be made as do not carry out reporting if under the also uncompleted state of communication (obtaining) of above-mentioned guidance information, just report by guiding.
In such present embodiment, guider 2 is in the timing of crossing communication beginning place Pk from garage, and the guidance information request instruction that will include speed information sends to information center 3.So, in information center 3,, guiding is reported the position of beginning place Ph and is adjusted according to the speed of a motor vehicle.Like this,, guiding is reported the position of beginning place Ph and adjusted, thereby guider 2 can reported beginning at the guiding of introductory object place Pt to carrying out from the best timing of car according to speed information.
Therefore, the driver can know the relevant guidance information with introductory object place Pt in the timing of the best, can avoid the urgent reply that close control object place Pt too causes of reporting regularly, also not exist to report regularly to make the introductory object place Pt unclear undesirable condition that becomes itself too in advance with respect to introductory object place Pt because of guidance information.
Particularly, then report the position of beginning place Ph if the speed of a motor vehicle is very fast to adjust above-mentioned guiding from car position direction, then adjust the position that beginning place Ph is reported in above-mentioned guiding if the speed of a motor vehicle 15 is slow to introductory object place Pt direction, so when the speed of a motor vehicle is very fast, can be in the promptly best timing of the timing of doing sth. in advance, know at the guiding in introductory object place and report, when the speed of a motor vehicle is slow, can the timing that postpones promptly this situation best know that regularly guiding reports.
Particularly, according to present embodiment, except above-mentioned speed information,, guiding is reported the position of beginning place Ph and adjusted also according to the complexity of introductory object place Pt.For example, as mentioned above, under the Pt complicated situation of introductory object place, make guiding report the position of beginning place Ph to being offset from car position direction (front side), under the simple situation of introductory object place Pt, make position that guiding reports beginning place Ph to introductory object place Pt direction (rear side) skew or do not adjust the position that beginning place Ph is reported in guiding, the result becomes further best guiding under regularly and reports beginning.
In addition, according to present embodiment, control device 4 makes to be reported beginning place Ph and but not to finish when obtaining from the guidance information of information center 3 having passed through guiding from car, do not make display 7 and voice output 9 report action, so can not guarantee under the situation of driver to reply time of reporting, report itself and be not carried out, thereby can keep safe driving.
(second embodiment)
Then, second embodiment is described.Fig. 4 A, Fig. 4 B are the related process flow diagrams of second embodiment, and in this second embodiment, the position that guider 2 is reported beginning place Ph according to the speed of a motor vehicle to guiding is adjusted.That is, in step T2, the guidance information request instruction that does not comprise speed information is sent to information center 3.Like this, beginning place adjustment is reported in not channeling conduct in information center 3, in step S3 beginning place and guidance information is reported in the guiding of default storage and is sent to guider 2.
And, in guider 2, as if the message pick-up of finishing from information center 3 (step T4), then in step Ta, complexity according to from the speed information and the introductory object place Pt of car adopts the mode identical with first embodiment, beginning place Ph is reported in guiding adjust.Also be to access the effect identical in this second embodiment with the first above-mentioned embodiment.
(the 3rd embodiment)

In this case, the above-mentioned communication position that begins place Pk also can be adjusted based on transport information.Like this, on the basis of considering transport information such as traffic congestion, accident, construction, adjust the position of communication beginning place Pk best.For example, can dope till the Pt of introductory object place by traffic congestion, accident, construction etc. can spended time, so can adjust the position of communication beginning place Pk its position from acquiescence is offset to introductory object place Pt direction.
(the 4th embodiment)
Fig. 6 A to Figure 12 shows the 4th embodiment of the present invention.This Fig. 6 A illustrates the control content of the control device 4 of guider 2, and Fig. 6 B shows the control content of the control part 16 of information center 3.The difference of the 4th embodiment and above-mentioned first embodiment is, except the position of guiding being reported beginning place Ph is adjusted, guider 2 also begins condition according to the communication of storing in advance respectively and the beginning condition is reported in guiding, communicate by letter beginning and guiding is reported begin to control.For the ease of understanding, describe below with reference to Fig. 7.The parallel road form of the road that for example road category is different (super expressway and ordinary road) has been shown in this Fig. 7, has shown the situation that outlet is arranged midway at super expressway.Introductory object place Pt among this Fig. 7 is made as the place on the super expressway.Communication beginning place Pk is the scope from predetermined centre coordinate c predetermined radii r, it is scope from predetermined centre coordinate c ' predetermined radii r ' that beginning place Ph is reported in guiding, in the scope of beginning place Ph is reported in this guiding, no matter vehicle travels on super expressway still is ordinary road, can both begin to communicate with information center 3.
Situation that among this Fig. 7, vehicle has shown in Reference numeral Sa among the figure situation of only travelling like that on super expressway, travel to ordinary road from super expressway like that shown in Reference numeral Sb and the situation of shown in Reference numeral Sc, only travelling like that in ordinary road.At this, introductory object place Pt is positioned on the super expressway, reports so need not channeling conduct under the situation of driving path Sb, Sc, needs channeling conduct to report under the situation of driving path Sa.Can carry out this guiding corresponding with travel conditions in the 4th embodiment reports.
Below, describe based on Fig. 6 A, 6B.
At first, in Fig. 6 B, in step V1, the transport information that reception is sent from various servers 20, VICS center 21, other vehicles etc. (information such as traffic congestion, accident, construction, track restriction, traffic restriction), in step V2, based on these transport information, make graphical information as guidance information.
In step V3, if receive the guidance information request instruction that includes speed information from guider 2, then in step V4, complexity according to above-mentioned speed information and introductory object place, the guiding of default storage being reported the position in beginning place adjusts, in step V5, will carry out this adjusted guiding and report beginning place and guidance information and send to guider 2.
On the other hand, the control device 4 of guider 2 detects in step W1 after the car position as shown in Figure 6A, judges from whether travelled the communication of storage in advance of car to begin place Pk in step W2.If be judged as and travelled, then in step W3, detect direct of travel from car, in step W4, detect the kind (for example, super expressway or ordinary road) of the road that gets carrying out map match from car.That is to say, detect travel conditions from car.
And, in step W5, judge from the travel conditions (be direct of travel and road category under this situation) of car whether to begin term harmonization with communicating by letter.Current for example in Fig. 8 A, under introductory object place Pt is positioned at situation on the ordinary road, shown in (a) hurdle of Fig. 9, communication beginning condition is that road category is that ordinary road, direct of travel are east orientation, be that ordinary road, direct of travel are under the situation of east orientation from road category among the travel conditions of car, from the travel conditions and the beginning term harmonization of communicating by letter of car, so in step W6, send the guidance information request instruction (communication beginning) that includes speed information.In addition, under the travel conditions of car and the inconsistent situation of beginning condition of communicating by letter, do not begin communication (step W17).
Afterwards, if report beginning place Ph by guiding before, finish reception (being "Yes" among step W7, the step W8), then in step W9, detect from the car position, in step W10 if be judged as guide report the beginning place Ph travel, then in step W11, detect direct of travel once more, in step W12, detect the road category (for example super expressway, ordinary road) that gets carrying out map match from car from car.That is to say, detect travel conditions from car.
And, in step W13, judge whether report the beginning term harmonization with guiding from the travel conditions of car.
For example, shown in (a) hurdle of Figure 10, it is that road category is an ordinary road that the beginning condition is reported in the guiding corresponding with above-mentioned Fig. 8 A, and direct of travel is an east orientation, if from travel conditions and this term harmonization of car, then begins guiding and report in step W14.
Afterwards, in step W15, passed through introductory object place Pt, then in step W16, finished guiding and report if be judged as.In addition, inconsistent as if being judged as in above-mentioned steps W13, then (step W18) reported in not channeling conduct.
