Fig. 3 b represents the simple navigational figure 330 in secondary display device 4 displayed as described above, as it can be seen, simple navigational figure 330 represents on figure 331 is illustrated in the intersection showing schematically intersection shape guides figure 332 by direction by direction by what arrow illustrated this intersection.It addition, control portion 16 also carries out showing the title 333 of this intersection together with such simple navigational figure 330, from current location to the process of distance 334 etc. of this intersection.Additionally, Fig. 3 b is also intersection is the figure of the situation at circle crossing.
Illustrate such navigation system generates the action of the simple navigational figure 330 for circle crossing below.
Control portion 16 is with reference to the current location being set in memorizer 15, guiding route, the link component of map datum, set and guide route, and the link attribute at the link data of above-mentioned map datum represents on the link guided on route of the link constituting circle crossing, detect that current location is close to time within preset distance, using include this close link circle crossing as object circle crossing, perform the circle crossing navigational figure generation shown in Fig. 4 and process.
As it can be seen, control portion 16 is in this circle crossing navigational figure generation processes, the link component of data calculates center O (step 402) at object circle crossing the most according to the map.
Here, the center at object circle crossing is as shown in Figure 6 by calculating cornerwise intersection point 602 of the rectangle 601 being cut in outward object circle crossing 600 as the center O at object circle crossing.Additionally, the rectangle (including square) 601 being cut in outward object circle crossing 600 such as can be obtained as following rectangle, object circle crossing the line of the coordinate that the group of the minima of coordinate that the group of the maximum of the latitudinal maximum of the coordinate of the node included and longitudinal is represented by this following rectangle and the latitudinal minima of node included by object circle crossing and longitudinal represents is as a diagonal.
Return to Fig. 4, then, process by exiting road direction calculating, calculate originate in object circle crossing respectively exit road exit direction, road (step 404).
In exiting road direction calculating process, in order to smoothly enter/exit object circle crossing, the place started towards the change of the ring circumferential direction at object circle crossing in the direction of object road, i.e. looks up in the side left from object circle crossing and is estimated as the place that the direction of object road is stable compared with this place and obtains as with reference to place.Then, for entering road, using calculating towards the direction of the center O at object circle crossing as road direction with reference to place from obtain, for exiting road, the center O from object circle crossing is calculated towards the direction with reference to place obtained as road direction.
Here, Fig. 5 a represents such step exiting road direction calculating process.
As shown in the figure, in this exits road direction calculating process, first, perform according to guiding the road entering object circle crossing in the case of route running as entering road, road will be entered and process (step 502) as the road direction calculating of object road.
Here, as shown in Figure 5 b, in road direction calculating processes, the road direction of object road calculated as described below.
I.e., first, in figure 7 a, label 700 represents object road, sets circle crossing 600 and junction point A (step 552) of object road 700.
Then, setting travels place S (step 554) of path distance P1 on object road 700 from junction point A.
Here, according to the average lane width of the object ring route periphery of the object road represented by the link data of the link of object road, road width is the biggest, and P1 is set to the biggest.
I.e., such as, in the case of road width is less than 6m, P1 is 3m, road width be 6m less than 13m in the case of, P1 is 6m, road width be 13m less than 25m in the case of, P1 is 13m, and in the case of road width is more than 25m, P1 is 25m.
Further, as shown in Figure 7a, place B (step 556) of predetermined path distance K (such as, the K=50m) that advance on object road 700 from junction point A is set.
Further, as shown in Figure 7a, place C (step 558) in the object road 700 of the beeline maximum calculating the straight line being connected with by junction point A and place B.
And, whether investigation place C more depends on junction point A side (step 560) than place S, if place C is not that then whether distance D of the straight line that investigation place C is connected with by junction point A and place B is more than P2 (step 562) more by the place of junction point A side than place S.
Here, according to the average lane width of the object ring route periphery of the object road represented by the link data of the link of object road, road width is the biggest, and P2 is set to the biggest.
I.e., such as, in the case of road width is less than 6m, P2 is 3m, road width be 6m less than 13m in the case of, P2 is 6m, road width be 13m less than 25m in the case of, P2 is 13m, and in the case of road width is more than 25m, P2 is 25m.
Further, if distance D of straight line that place C is connected with by junction point A and place B is more than P2, the most as shown in Figure 7b place C is set as new place B (step 564), returns to the process started from step 558.
On the other hand, in step 560, it is judged that for place C be than place S more by junction point A side place in the case of, in step 562, in the case of being judged to that beeline D of the straight line that place C is connected with by junction point A and place B is below P2, carry out following process.
I.e., if object road is for entering road (step 566), the most as shown in Figure 7b, using the place B in this moment as with reference to place, to process towards the road direction (step 568) that direction setting is object road of the center O at object circle crossing, end from reference to place.On the other hand, if object road is not to enter road but exits road (step 566), then using the place B in this moment as with reference to place, on the contrary the center O from object circle crossing is processed towards the road direction (step 570) that direction setting is object road with reference to place, end.
Above road direction calculating is processed and be illustrated.
Process according to such road direction calculating, by than the place S in object road away from the place at object circle crossing, and in order to smoothly enter/exit object circle crossing, using the direction of object road towards the place of the change beginning of the ring circumferential direction at object circle crossing as reference place, the direction that the center O with reference to place and object circle crossing connects is calculated as road direction.
Here, only will be as the purpose obtained with reference to place away from the place at object circle crossing than the place S in object road: due near object circle crossing, road shape is complicated, the probability the most correctly realizing map datum is big, therefore from reference to the place got rid of place near such object circle crossing.Additionally, reason also resides in: than the place S in object road more by side, object circle crossing, is equivalent to the probability importing road/lead path part that changed towards the ring circumferential direction at circle crossing in the direction of road in order to object road smoothly enters/exit object circle crossing greatly.
Additionally, it is as with place B for the reason of the condition with reference to place using beeline D of the straight line that junction point A and place B is connected and object road for below P2 this point, if with the situation that beeline is zero of the straight line that junction point A and place B are connected and object road as condition, even if the then part near the object circle crossing of object road, in the case of there is curve slightly, the most all the time place S is calculated as with reference to place, and distance D is as described above within the P2 set as substantially road width, the most as shown in Figure 7 c, the straight line connected by junction point A and place B is by the straight line within road, if therefore in the error in view of map datum, then it is considered as in allowed band.
Return to Fig. 5 a, executed as described above to enter the road road direction calculating process as object road, if calculating the road direction entering road, the most then perform to can be used for each road of exiting from object circle crossing as exiting road (step 504,508,510), and this is exited road process (step 506) as the road direction calculating of object road.
Further, calculate, by road direction calculating process, the road direction respectively exiting road if as discussed aboveThen direction, the road θ n that exits respectively exiting road is calculated (step 512) as the road direction to enter road for direction during top.That is, to be upwardly-directed zero to measure angle along clockwise direction, as shown in Figure 8 a, the road direction entering road I has been obtainedRespectively exit the road direction of road E1～E4In the case of, as shown in Figure 8 b, respectively exit the road direction θ 1～θ 4 of road E1～E4 by making each road directionRotate-As And obtain.But, the direction, road of exiting so obtained can normalization be also direction nearest in any one in 16 directions being represented by the solid line in Fig. 8 c further.
Then, terminate to exit road direction calculating to process.
Afterwards, return to Fig. 4, calculate if as discussed above start from object circle crossing respectively exit road exit direction, road, then generate simple navigational figure 330 (step 406) then according to the direction, road of exiting respectively exiting road obtained, end processes.
Following this simple navigational figure 330 of generation.
As illustrated in fig. 9, road E1～E4 is exited in object circle crossing calculating 4 and exits direction, road that is 4 direction θ 1～θ 4 relative to entering road I, according to guide route object circle crossing by path R from enter road I enter object circle crossing 600, in the counterclockwise direction around object circle crossing 600, from object circle crossing 600 by calculate exit direction, road be θ 3 exit road E3.
In the case, first, as shown in figure 9b, generate and in ring-like pattern, synthesize the intersection of the branch's figure figure of road I (simulation enter) having 4 the branch's figures (simulate 4 figures exiting road E1～E4) extended along 4 directions exiting direction, road θ 1～θ 4 from the viewing of the center of ring-like pattern and the lower section from ring-like pattern to extend along the center position of ring-like pattern to the outside of ring-like pattern from ring-like pattern laterally illustrate figure 331.
Then, as is shown in fig. 9 c, would indicate that edge guides being drawn on intersection signal figure 331 by direction guiding figure 332 of the pass course R at the object circle crossing of route on intersection signal figure 331, generates simple navigational figure 330.Figure 332 is guided to be made up of following arrow figure by direction: center position along ring-like pattern extends to the arrow figure of the root of the figure of the entrance road I of analog crossover crossing signal figure 331 from the lower section of ring-like pattern；What the simulation from the front position of this arrow figure to intersection illustrates figure 331 started from object circle crossing leaves the root that the figure of road E3 is i.e. exited on road, after extending along the ring-like pattern ring circumferential direction to object circle crossing, i.e. exit, along the road of leaving starting from object circle crossing, the arrow figure that the direction exiting direction, road θ 3 of road E3 extends from the viewing of the center of ring-like pattern.
Wherein, also can as shown in figure 9d as, generate the simple navigational figure 330 shown in Fig. 9 c being simulated image that 3-dimensional represents (tilt nearly front side top from paper and watch the simple navigational figure 330 of Fig. 9 c and the image that represents) as the simple navigational figure 330 at final object circle crossing.
It addition, generate simple navigational figure 330 for object circle crossing if as discussed above, then terminate ring-type crossroad guide image generation and process.
