With reference to the process flow diagram of Fig. 2 A and Fig. 2 B, the control action of the control device 4 of guider 2 and the control part 16 of information center 3 is described.
First, the control part 16 of information center 3 as shown in Figure 2 B, if receive from guider 2 the guidance information request instruction that includes speed information in step S1, in step S2, according to the complexity in above-mentioned speed information and introductory object place, the guiding of default storage is reported to the position in beginning place and adjusted; In step S3, this guiding after adjusting is reported and started place and guidance information sends to guider 2.
That is, in above-mentioned steps S2, adjust, make the speed of a motor vehicle (having carried the speed of the vehicle of guider 2) faster, guiding is reported and is started place Ph (referring to Fig. 3) more to being offset from car current location P direction (direction of arrow A in Fig. 3).In other words, adjust, make Vehicle Speed slower, this guiding is reported beginning place Ph and more to introductory object place Pt direction (direction of arrow B in Fig. 3), is offset.
And, in the present embodiment, being reported, the guiding of acquiescence starts place Ph while adjusting, also consider in the lump the complexity in the speed of a motor vehicle, introductory object place.
For example, when introductory object place Pt is ordinary road and is while keeping straight on (complexity is lower), in the speed of a motor vehicle, be that 50km/h is above in the situation that, the guiding of acquiescence is reported to beginning place Ph to be adjusted, make it to front, be offset 100m (to from car current location P direction), when the speed of a motor vehicle is when being greater than 30km/h and being less than 50km/h, guiding is reported beginning place Ph and is remained unchanged, in the speed of a motor vehicle, be that 30km/h is following in the situation that, the guiding of acquiescence is reported to beginning place Ph and adjust, make to be rearward offset 100m (introductory object place Pt direction).
In addition, when introductory object place Pt is ordinary road and while turning left or turning right (complexity is high), in the speed of a motor vehicle, be that 50km/h is above in the situation that, the guiding of acquiescence is reported to beginning place Ph to be adjusted, make it to front, be offset 150m (to from car current location P direction), when the speed of a motor vehicle is when being greater than 30km/h and being less than 50km/h, the guiding of acquiescence is reported to beginning place Ph to be adjusted, make it to front, be offset 50m (to from car current location P direction), in the speed of a motor vehicle, be that 30km/h is following in the situation that, the guiding of acquiescence is reported to beginning place Ph to be adjusted, make it rearward be offset 50m (introductory object place Pt direction).
In addition, in the situation that being super expressway, the speed of a motor vehicle is when 80km/h is above, the guiding of acquiescence is reported and started place Ph and adjust, make it to front, be offset 300m (to from car current location P direction), when the speed of a motor vehicle is when being greater than 50km/h and being less than 80km/h, guiding is reported beginning place Ph and is remained unchanged, in the speed of a motor vehicle, be 50km/h when following, the guiding of acquiescence is reported and started place Ph and adjust, make it rearward be offset 400m (introductory object place Pt direction).
In addition, sometimes also can be judged as and can former state keep the guiding of acquiescence to report beginning place Ph, in this case, not change.
On the other hand, as shown in Figure 2 A, in step T1, the pre-stored communication that judges whether to travel starts place Pk (referring to Fig. 3) to the control device 4 of guider 2.If be judged as, travelled,, in step T2, the guidance information request instruction that includes speed information was sent to information center 3.
In addition, in Fig. 3, an example that represents introductory object place with the Reference numeral Pt of Fig. 3, represents from car current location with Reference numeral P.
In addition,, in the situation that guidance information being shown on display 7, except showing map, also with show tags M, represent introductory object place Pt (referring to Fig. 3).In addition with show tags Ms, represent from vehicle.In addition, this Fig. 3 shows on display 7 example showing, but above-mentioned communication starts place Pk and guiding, reports and starts place Ph and do not show.
In following step T3, judge whether under the state receiving from the information of information center 3, just to have crossed guiding and report and start place Ph not completing.In the situation that being judged as "No", transfer to step T4, judged whether information reception.At this, if completed information reception, in step T5, whether judgement had travelled to guide to report from car starts place Ph, travels, if be judged as in step T6, make display 7 and voice output 9 work, the guidance information of obtaining is reported.
Afterwards, in step T7, if be judged as, passed through introductory object place Pt, in step T8, finished guiding and report.
In addition,, if also just report beginning place Ph (being "Yes") by guiding under uncompleted state in step T3 in the communication (obtaining) of above-mentioned guidance information,, in step T9, reporting of guidance information is made as and do not carry out reporting.
In such present embodiment, guider 2 Zi garages cross the timing that communication starts place Pk, and the guidance information request instruction that includes speed information is sent to information center 3.So, in information center 3, according to the speed of a motor vehicle, guiding is reported to the position of beginning place Ph and is adjusted.Like this, according to speed information, guiding is reported to the position that starts place Ph and adjust, thereby guider 2 can be for carrying out from the best timing of car and reporting for the guiding of introductory object place Pt.
Therefore, driver can know the guidance information relevant to introductory object place Pt in best timing, can avoid the urgent reply that regularly too close control object place Pt causes of reporting because of guidance information, also not exist to report regularly with respect to introductory object place Pt to make too in advance the introductory object place Pt unclear undesirable condition that becomes itself.
Particularly, if the speed of a motor vehicle is very fast, to adjust above-mentioned guiding from truck position direction, report the position that starts place Ph, if the speed of a motor vehicle 15 is slow, to introductory object place Pt direction, adjust the position that beginning place Ph is reported in above-mentioned guiding, so when the speed of a motor vehicle is very fast, can be best timing in the timing of doing sth. in advance, know for the guiding in introductory object place and report, when the speed of a motor vehicle is slower, can knows to guide in the i.e. best timing of this situation of the timing postponing and report.
Particularly, according to present embodiment, except above-mentioned speed information, also according to the complexity of introductory object place Pt, guiding is reported to the position of beginning place Ph and adjusted.For example, as mentioned above, under the Pt complicated situation of introductory object place, guiding is reported and started Xiang Zi truck position, position direction (front side) skew of place Ph, in the simple situation of introductory object place Pt, the position that makes guiding report beginning place Ph is offset or does not adjust guiding to introductory object place Pt direction (rear side) and reports the position that starts place Ph, result, and beginning is reported in the guiding becoming under further best timing.
In addition, according to present embodiment, control device 4 makes to report and start place Ph and but do not complete while 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 in the situation that can not guarantee that driver is to the reply time of reporting, report itself and do not carried out, thereby can maintain safe driving.
(the second embodiment)
Then, the second embodiment is described.Fig. 4 A, Fig. 4 B are the related process flow diagrams of the 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, in information center 3, do not guide and report beginning place adjustment, the guiding of default storage is reported to beginning place and guidance information in step S3 and sent to guider 2.
And, in guider 2, if the information completing from information center 3 receives (step T4), in step Ta, according to the complexity of the speed information from car and introductory object place Pt, adopt the mode identical with the first embodiment, guiding is reported to beginning place Ph and adjust.In this second embodiment, also, can access the effect identical with the first above-mentioned embodiment.
(the 3rd embodiment)
Fig. 5 shows the 3rd embodiment of the present invention.
The speed of a motor vehicle of guider 2 based on from car, the communication that adjustment map data base 10 is stored starts the position of place Pk.In this situation, arrive communication beginning place Pk from car before, adjust the position that communication starts place Pk, if make the speed of a motor vehicle comparatively fast make the position of communication beginning place Pk to being offset from car current location P direction, if the position that the speed of a motor vehicle makes communication start place Pk is slowly offset to introductory object place Pt direction.According to this embodiment, can start accordingly to communicate by letter with travel speed.For example, in the situation that travelling speed, communication starts regularly ahead of time, thus can avoid communication failure, and when traffic congestion, communication starts constant time lag, so can obtain up-to-date guidance information.
In this case, the position that above-mentioned communication starts place Pk also can be adjusted based on transport information.Like this, considering on the basis of the transport information such as traffic congestion, accident, construction, adjusting best the position that communication starts place Pk.For example, by traffic congestion, accident, construction etc., can dope till the Pt of introductory object place and understand 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 the content of the control device 4 of guider 2, and Fig. 6 B shows the Control the content of the control part 16 of information center 3.The difference of the 4th embodiment and above-mentioned the first embodiment is, the position that starts place Ph except guiding is reported is adjusted, guider 2 also according to pre-stored respectively communication, starts condition and beginning condition is reported in guiding, and communicate by letter beginning and guiding are reported and started to control.For the ease of understanding, below with reference to Fig. 7, describe.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 has outlet midway at super expressway.Introductory object place Pt in this Fig. 7 is made as the place on super expressway.It is the scope of predetermined radii r from predetermined centre coordinate c that communication starts place Pk, it is the scope of predetermined radii r ' from predetermined centre coordinate c ' that beginning place Ph is reported in guiding, in the scope that starts place Ph is reported in this guiding, no matter vehicle travels in super expressway or ordinary road, can both start to communicate with information center 3.
In this Fig. 7, the situation that vehicle has the situation of only travelling on super expressway as shown in Reference numeral Sa in figure, the situation of travelling to ordinary road from super expressway as shown in Reference numeral Sb and only travels in ordinary road as shown in Reference numeral Sc.At this, introductory object place Pt is positioned on super expressway, so report without guiding the in the situation that of driving path Sb, Sc, needs to guide and report the in the situation that of driving path Sa.In the 4th embodiment, can carry out this guiding corresponding with travel conditions reports.
Below, based on Fig. 6 A, 6B, describe.
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 the graphical information as guidance information.
In step V3, if receive the guidance information request instruction that includes speed information from guider 2, in step V4, according to the complexity in above-mentioned speed information and introductory object place, the guiding of default storage being reported to the position in beginning place adjusts, in step V5, by carrying out guiding after this adjustment, report and start place and guidance information sends to guider 2.
On the other hand, the control device 4 of guider 2 as shown in Figure 6A, detects after truck position in step W1, and in step W2, judgement starts place Pk from the car pre-stored communication of whether having travelled.If be judged as, travelled, in step W3, detected the direct of travel from car, in step W4, detected the kind (for example, super expressway or ordinary road) of the road obtaining carrying out map match from car.That is to say, detect the travel conditions from car.
And, in step W5 judgement from the travel conditions (be direct of travel and road category in this situation) of car whether with the beginning term harmonization of communicating by letter.Current for example in Fig. 8 A, in the situation that introductory object place Pt is positioned in ordinary road, as shown in (a) hurdle of Fig. 9, communication beginning condition is that road category is that ordinary road, direct of travel are east orientation, in the situation that road category is that ordinary road, direct of travel are east orientation 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 starts) that includes speed information.In addition, the travel conditions from car with communicate by letter in the inconsistent situation of beginning condition, do not start communication (step W17).
Afterwards, if completed reception (being "Yes" in step W7, step W8) report beginning place Ph by guiding before, in step W9, detect from truck position, if be judged as in step W10, guide to report and start place Ph and travel, in step W11, again detect the direct of travel from car, in step W12, detect the road category (for example super expressway, ordinary road) obtaining carrying out map match from car.That is to say, detect the travel conditions from car.
And in step W13, whether judgement reports beginning term harmonization with guiding from the travel conditions of car.
For example, as shown in (a) hurdle of Figure 10, it is that road category is ordinary road that beginning condition is reported in the guiding corresponding with above-mentioned Fig. 8 A, and direct of travel is east orientation, if from travel conditions and this term harmonization of car, in step W14, starts guiding and reports.
Afterwards, in step W15, if be judged as, passed through introductory object place Pt, in step W16, finished guiding and report.In addition,, if be judged as inconsistently in above-mentioned steps W13, do not guide and report (step W18).
Above-mentioned control is described as follows, and in Fig. 8 A, is in communication starts the situation that place Pk travels to east orientation in ordinary road from car, consistent with communication beginning condition ((a) hurdle of Fig. 9), so communicating by letter between beginning and information center 3.In addition, if from car the travel conditions beyond above-mentioned, do not start with information center 3 between communicate by letter.
In addition, similarly in Fig. 8 A, from car, be in guiding and report the travel conditions that beginning place Ph travels to east orientation in ordinary road, to report beginning condition ((a) hurdle of Figure 10) consistent with guiding, so guidance information is reported, under travel conditions in addition, do not guide and report.
In addition, the in the situation that of Fig. 8 B, in communication, start place Pk, when only the communication shown in (b) hurdle in Fig. 9 starts condition (east orientation and travel on super expressway) at the travel conditions from car, start communication, in guiding, report and start place Ph, when only beginning condition (east orientation and travel on super expressway) is reported in the guiding shown in (b) hurdle in Figure 10 at the travel conditions from car, guide and report.
In addition, the in the situation that of Fig. 8 C, in communication, start place Pk, when only the communication shown in (c) hurdle in Fig. 9 starts condition (east orientation and travel on super expressway) at the travel conditions from car, start communication, in guiding, report and start place Ph, when only beginning condition (east orientation and travel on super expressway) is reported in the guiding shown in (c) hurdle in Figure 10 at the travel conditions from car, guide and report.
In addition, the in the situation that of Fig. 8 D, communication starts place Pk and is positioned on a road, thus without definite road category, therefore, as shown in (d) hurdle of Fig. 9, as communication beginning condition, uncertain road category, direct of travel is set as east.In this case, in communication, start place Pk, as long as travel and just start communication to east orientation from car, and, as shown in (d) hurdle of Figure 10, it is east orientation and this condition of travelling on super expressway that beginning condition is reported in guiding, so just guide and report as long as enter into super expressway from car.
