If carry out the guiding output B of relevant guiding object point of crossing, the place ahead (C2), will indicate in the step ST14 that follows that then FL2 changes to 1, record has carried out the guiding output B of relevant guiding object point of crossing, the place ahead (C2).In step ST11, judge whether to handle terminal point then,, return step ST5 and handle, carry out the detection of the present position (C1) of moving body once more by present position detecting device 12 if be untreated until the path of setting by path setting device 13.Then, in step ST6, detect the distance (L1) of this present position (C1) and guiding object point of crossing, the place ahead (C2), in step ST7 according to the value of this distance (L1), the distribution of handling, if distance (L1) is bigger and below setting (L2), then whether distinguishing mark FL2 is 0 in step ST12 than setting (L3).At this moment owing to carried out guiding output B, distinguishing mark FL2 becomes 1, directly returns step ST5 so handle, and carries out this processing later on repeatedly, till distance (L1) reaches below the setting (L3).

If above-mentioned distance (L1) has reached below the setting (L3), then by the distribution of the processing carried out in step ST7, step ST15 is transferred in this processing.Indicate that in step ST15 whether FL3 is 0 identification, if sign FL3 is 0, then owing to also carry out hereinafter described guiding output C, so in step ST16, carry out the guiding output C of relevant guiding object point of crossing, the place ahead (C2).

This guiding output C takes out the guiding object point of crossing 201 of taking out as guiding object point of crossing, the place ahead (C2) shown in Figure 5 in quantization operations device 15, the road link 202 and the road link 203 that are connected with this guiding object point of crossing 201, and the present position 204 of moving body, it is quantified as simple arrow-shaped, shown in Fig. 6 (c), make it rounded, in addition with near the set of rectangle represent to lead the road shape 332 object point of crossing 331, overlap with the path 333 of guiding with arrow-shaped then, overlap with present position 334 with triangle, it is presented on the display 16, in acoustic information maker 17, generate simultaneously shown in the c hurdle among Fig. 7 of relevant this guiding object point of crossing, the place ahead (C2) " " navigation information soon to the right is by 18 outputs of voice output device.In addition, about this guiding output C, the point of crossing guiding figure shown in also can a displayed map 6 (c), the perhaps navigation information shown in the c hurdle in the output map 7.

If carry out the guiding output C of relevant guiding object point of crossing, the place ahead (C2), will indicate in the step ST16 that follows that then FL3 changes to 1, record has carried out the guiding output B of relevant guiding object point of crossing, the place ahead (C2).In step ST11, judge whether to handle terminal point then,, return step ST5 and handle, carry out the detection of the present position (C1) of moving body once more by present position detecting device 12 if be untreated until the path of setting by path setting device 13.Then, in step ST6, detect the distance (L1) of this present position (C1) and guiding object point of crossing, the place ahead (C2), in step ST7 according to the value of this distance (L1), the distribution of handling, if distance (L1) is below setting (L3), then whether distinguishing mark FL3 is 0 in step ST15.At this moment owing to carried out guiding output A, distinguishing mark FL3 becomes 1, directly returns step ST3 so handle, and each indicates that FL1, FL2, FL3 are initialized to 0, carries out the taking-up of guiding object point of crossing, the place ahead (C2) in step ST4.In step ST11, carry out above-mentioned a series of processing later on repeatedly, until detecting till the endpoint procedure in the path of being set by path setting device 13 finishes.

So, at moving body under the situation of travelling towards guiding object point of crossing on the path, when from the present position of this moving body to the distance of guiding object point of crossing when setting L2 (for example 1000m) is above, when promptly continuing to be straight moving condition, on display 16, carry out the guiding of carrying out shown in Fig. 6 (a) and show, simultaneously the navigation information shown in a hurdle in the output map 7 with display graphics 310.In addition, when from the present position of this moving body to the distance of guiding object point of crossing when setting L2 is following, guiding on the display 16 is shown that switching to the guiding of carrying out with display graphics 320 shown in Fig. 6 (b) shows, simultaneously the navigation information shown in the b hurdle in the output map 7.Then, reaching moment below the setting L3 (for example 300m) from the present position of this moving body to the distance of guiding object point of crossing, the guiding that switches to the general structure of this guiding object point of crossing of expression that the present position 334 by the path 333 of this guiding object point of crossing 331 shown in Fig. 6 (c) and near road shape 332 and guiding, moving body constitutes shows the navigation information shown in the c hurdle in the while output map 7.

Like this, if adopt this example 1, the demonstration of the map picture of the information that may not need when then not comprising actual travel, with simple graphic presentation paths such as arrows, so showing, picture becomes simple, in addition, according to distance to the object point of crossing of leading, displaying contents is changed by stages, the user can easily grasp the action that the place, guiding object point of crossing that turns etc. should take about guiding object point of crossing, can alleviate the burden of identification displaying contents aspect, according to navigation information, use the acoustic notifications path simultaneously, can reduce the necessity that the user sees the display frame that shows paths continually, so the user can attentively drive, has the effect that more safely to drive.

In addition, because showing, picture becomes simple, display device of the cheapness that so even picture display part is little or resolution is low, also can easily guarantee identifiability, have the effect of the display panel of the air conditioner that can be shared for example on the panel board of automobile etc., be provided with or the display panel of velometer etc.

In addition, in the above description, when guiding output A, B that only carries out relevant guiding object point of crossing or C, carry out the output of acoustic information shown in Figure 7, but by switching manipulation etc., the also corresponding acoustic information of guiding picture that can report at any time and at this moment on display 16, show by voice output device 18.By such processing, if the user carries out switching manipulation, can know the summary situation in path by acoustic information, when really needing, do not see that the guiding picture of display 16 is also passable, so can more intently drive.

In addition, in this example 1, imagination will be carried out among the ROM62 of procedure stores in control module 58 that quantization operations uses in advance, but also all or part of of this program can be deposited in the external memory medias such as CD-ROM, as required, utilize regenerating unit it to be read, be used for the quantization operations of being undertaken by quantization operations device 15 from this external memory media.By such processing, change program easily, can easily carry out the replacing or the edition upgrading of out of order part.

Example 2

In addition, in this example 1, owing to road-map is not presented on the display 16, so carrying out the path setting stage, the user is difficult in advance know along which paths and travels to the destination.This example 2 persons of being to use can know the setting to the destination in advance.

Fig. 9 is the block diagram of functional structure of the guiding device of expression example 2 of the present invention, and the part suitable with the each several part of example 1 is marked with the symbol identical with Fig. 2, and its explanation is omitted.Among the figure, the 19th, generate the roughly roughly path maker in path, be used for and be arranged in table by title, road name or road number on the path of path setting device 13 settings, the distance between the guiding object point of crossing etc. by guiding object cross point detection device 14 detected guiding object point of crossing, the 20th, set the site setting device of the anywhere on the above-mentioned path, be used for specifying will be by this indication range when roughly the roughly path that generates of path maker 19 is presented on the display 16.

The key diagram of the demonstration example in Figure 10 roughly path that to be expression generated by path maker roughly 19, among the figure, the 341st, the title of guiding object point of crossing, the 342nd, road informations such as road name between the guiding object point of crossing or road number, the 343rd, the distance between the guiding object point of crossing, the 344th, the present position of moving body.

Next illustrates working condition.

Here, Figure 11 is the process flow diagram of treatment scheme of the guiding device of this example 2 of expression.At first in step ST20, path setting device 13 utilizes two places on the map that settings such as longitude and latitude are read in by map information memory 11, sets path between these two places with the general heuristic algorithm on the networks such as Dijkstra (ダ イ Network ス ト ラ) method.Secondly in step ST21, will gaze at the departure place (S) of place (CC), in step ST22, counter i will be set at 1 again as the path.Here, what is called gaze at place (CC) be meant generate the place that is variable of using in handling in the roughly path that path maker 19 roughly carries out repeatedly, be the place of in repeated treatments, upgrading successively, making under the situation in path roughly, the departure place that the place is the path (S) is gazed in beginning, seek the guiding object point of crossing in the path in order, come the terminal point (G) in path at last.

In addition, to be expression distribute to from the departure place (S) in the roughly path that generated numbering to the key diagram of the pattern of the object point of crossing of respectively leading of the terminal point (G) in path to Figure 12, begin from the departure place (S) in path to each guiding object point of crossing distribute in order numbering CC1, CC2 ..., CCn, according to this in proper order the guiding object point of crossing in the searching order path until the terminal point (G) in path.

That is, in step ST23, at first detect the guiding object point of crossing (CCi) of gazing at the place ahead, place (CC).At this moment, because counter i is set to 1, so detect guiding object point of crossing (CC1).Secondly in step ST24, detect the distance L i that gazes between place (CC) and the guiding object point of crossing (CCi), in step ST25, detect road name Ri, the road number Ni that gazes between place (CC) and the guiding object point of crossing (CCi) again.Then, in step ST26,, upgrade and gaze at place (CC), make counter i increase by 1 simultaneously according to this detected guiding object point of crossing (CCi).Below, the processing that this step ST23 is later proceeds to till the terminal point (G) that detects the path in step ST27 repeatedly.

Therefore, according to distributing to departure place (S) as shown in figure 12 to the numbering (CCi) of all guiding object point of crossing of the terminal point (G) in path from the path, detect the object point of crossing of respectively leading in order, detect distance (Li) between these guiding object point of crossing and road name Ri and the road number Ni between the guiding object point of crossing simultaneously.

After this, in step ST28, set m1, the m2 that is used to specify the indication range on the path by site setting device 20.If carried out the setting of m1, m2, then in step ST29, will be presented on the display 16 about the point of crossing between guiding object point of crossing (CCm1) corresponding and the guiding object point of crossing (CCm2), the guiding of road with the m1 that sets, m2.In addition, at this moment as shown in figure 10, also can show the present position 344 of moving body together.Here, figure 10 illustrates situation about showing is vertically arranged in guiding object point of crossing 341, but can certainly transversely arrangedly show.

In addition, in the above description, show the situation of the demonstration of only carrying out the roughly path that once generated, but return Figure 11 (A), also can supervise the user whether to change the m1 that is undertaken by site setting device 20, the setting of m2, carry out the roughly demonstration input in path once more, carry out the following processing of step ST28 repeatedly.

Like this, if adopt this example 2, then since respectively lead object point of crossing and the road information between them that will be on the path of setting between 2 on the map as path roughly and formization, so that can show it, so can be with the present position irrelevant and the pattern in path is grasped as character, have the user and just can know in advance in the path setting stage and walk the effect that could arrive the destination along any paths.

In addition, in the above description, illustrated that the Presentation Function in path roughly is added in the situation in the guiding device shown in the example 1, but also can be applicable to the guiding device of other form to have the effect same with above-mentioned example 2.

In addition, in above-mentioned example 2, imagination will be carried out among the ROM62 of procedure stores in control module 58 of the generation usefulness in path roughly in advance, but also all or part of of this program can be deposited in the external memory medias such as CD-ROM, as required, utilize regenerating unit it to be read, be used for the generation in the roughly path of being undertaken by path maker 19 roughly from this external memory media.By such processing, change program easily, can easily carry out the replacing or the edition upgrading of out of order part.

Example 3

In addition, in above-mentioned example 2, show path roughly is presented at situation on the display 16, but also can utilize acoustic information that it is reported to the user.

Figure 13 is the block diagram of functional structure of the guiding device of the such example of the present invention 3 of expression, and the part suitable with the each several part of example 2 is marked with the symbol identical with Fig. 9, and its explanation is omitted.Among the figure, the 21st, the acoustic information maker, but the parts of representing with symbol 17 among following situation and Fig. 9 are different, promptly in the acoustic information storer that install inside, also storing the title that comprises with acoustic notifications guiding object point of crossing as the sound waveform data, about turn, road information such as road name or road number, distance between the guiding object point of crossing, the word of the information of usefulness such as address title or phrase etc., when having generated roughly the path, select the sound waveform data corresponding with it by path maker 19 roughly, and carry out output to voice output device 18.

Figure 14 is that expression is by the routine key diagram of one of acoustic information of this acoustic information maker 21 selections/outputs, among the figure, the 421st, the guiding object that is undertaken by sound, the 422nd, with the corresponding acoustic information of this guiding object 421, the 423rd, the travel direction on the path, the 424th, the acoustic information corresponding with this travel direction 423.In addition, the 425th, one of roughly path report information that makes according to them example.

Next illustrates working condition.

Here, Figure 15 is the process flow diagram of treatment scheme of the guiding device of this example 3 of expression.At first the path setting between these two places is carried out in two places on the setting map in step ST30, in addition, will gaze at the departure place (S) of place (CC) as the path in step ST31, and making counter i in step ST32 is 1.Secondly in step ST33, detect the guiding object point of crossing (CCi) of gazing at the place ahead, place (CC), in step ST34, detect the distance (Li) of gazing between place (CC) and the guiding object point of crossing (CCi), in step ST35, detect road name (Ri), the road number (Ni) gazed between place (CC) and the guiding object point of crossing (CCi).Secondly in step ST36, will gaze at place (CC) as guiding object point of crossing (CCi), and make counter i increase by 1 simultaneously.Then, in step ST37, detect the terminal point (G) in path, carry out the later processing of step ST33 repeatedly, until the terminal point (G) that in step ST37, detects the path.Processing before this is identical with the situation of example 2.

If in step ST37, detect the terminal point (G) in path, then enter step ST38, make counter i return 1.Then, acoustic information makes to grow up to be a useful person 21 values according to this counter i in step ST39, with the guiding sound of road name (Ri) between relevant guiding object point of crossing (CCi), the guiding object point of crossing and road number (Ni) (for example, according to guiding object 421, travel direction 423, from acoustic information shown in Figure 14 422 or the 424 guiding sound of selecting) export to voice output device 18.Secondly in step ST40, make counter i increase by 1, in step ST41, detect the terminal point (G) in path, carry out the later processing of above-mentioned steps ST39 repeatedly, until the terminal point (G) that in step ST41, detects the path.

Therefore, order along the path, by voice output device 18 will be for example " from the departure place; go down south " along No. 176 national highways, " turning right in god's bridge point of crossing at about forwardly 5km place; westwards travels along No. 82 drawing lines ", " about forwardly 500m turns left at the place to western palace north conversion inlet; on the Chinese highway towards Osaka direction running " etc. Figure 14 in report to the user as the roughly path report information 425 shown in the example, and from the departure place in path, along the order in path by the voice output device 18 object point of crossing of will leading, road name or road number, travel direction, interval distance waits and reports to the user.

In other words, from above-mentioned steps ST30 to step ST37, lead object point of crossing and therebetween road name, interval distance, the detection of travel direction, from step ST38 to step ST41, read detected guiding object point of crossing and road name therebetween, interval distance, travel direction etc. along the sound reproduction of the order in path.

Like this, if adopt this example 3, then since with respectively the lead object point of crossing of acoustic notifications on the path of setting between 2 on the map reach therebetween road information by the form change roughly path, even can not know the pattern in path so the user does not see display frame yet, the user need not leave the place ahead with notice in driving procedure, have the effect of the safer driving of energy.

In addition, in the above description, illustrated will with acoustic notifications roughly the function in path be attached to situation in the guiding device shown in the example 2, but also can be applicable to the guiding device of other form, have the effect same with above-mentioned example 3.

Example 4

In addition, in above-mentioned example 1, owing to road-map is not presented on the display 16, when so moving body does not travel on the path of being set by path setting device 13 when resembling indication guiding object point of crossing bending loses being arranged or when never the place in parking lot begins to lead etc., be difficult to know whether can be from the present position along which direction running how long distance just can return the path of setting.This example 4 is to know that moving body arrives the distance in the path of setting and the example of direction from the present position.

Figure 16 is the block diagram of functional structure of the guiding device of the such example of the present invention 4 of expression, and the part suitable with the each several part of example 1 is marked with the symbol identical with Fig. 2, and its explanation is omitted.Among the figure, the 22nd, the path arrives distance detector, and its is according to the path of being set by path setting device 13, and map data stored detects distance and the direction between the present position of this path and moving body from map information memory 11.

Figure 17 is present position and distance path between and direction one of the routine key diagram of expression by the moving body of path arrival distance detector 22 detections, among the figure, and the 351st, the present position of moving body, the 352nd, near the path the present position 351 of this moving body.The 353rd, the near point on the path of present position 351 proximal most position of the moving body of expression on the path 352, the 354th, connect the straight line of the present position 351 of near point 353 on this path and moving body, the 355th, the present position 351 of the moving body of representing with this straight line 354 and the air line distance of the near point 353 on the path.

Next illustrates working condition

Here, Figure 18 is the process flow diagram of treatment scheme of the guiding device of this example 4 of expression.At first in step ST50, detect the present position (C1) of moving body by present position detecting device 12.Secondly in step ST51, judge that detected present position (C1) whether on the present path of being set by path setting device 13, directly finishes this processing in the time of on the path.On the other hand, present position (C1) enters step ST52 not on the path of setting the time, detects on the path apart from the near point (K1) on present position (C1) nearest path.Specifically, in the map datum that is read in by map information memory 11, consider with present position (C1) be the center, radius bit by bit becomes big circle since 0, with the point on initial and the path that this circle contacts as the near point on the path (K1).

Secondly in step ST53, detect the distance (L1) between the near point (K1) on above-mentioned detected present position (C1) and the path.In addition, this distance (L1) is to try to achieve with the radius of near point (K1) when contacting on the path as above-mentioned circle.Secondly in step ST54, as shown in figure 17, according near point (K1) on above-mentioned detected present position (C1), the path and distance (L1), the present position 351 of moving body, near path 352, near point 353, straight line 354 and the air line distance 355 on the path are presented on the display 16.After this, step ST50 is returned in processing, carry out above processing repeatedly, become till on the path until the present position of moving body.

In addition, when on display 16, showing, about near the path 352 the present position 351 of moving body, near the part present position of the moving body on the path that taking-up sets from map datum, with quantification arithmetical unit 15 it being quantified as simple arrow-shaped shows, the user can easily grasp shown content, can discern the little simple demonstration of burden.

Like this, if adopt this example 4, even then the present position of moving body is not on the path, also can be with certain direction and the distance in simple graphic presentation path, even do not show road-map, also can sensuously learn, move the effect how many distances just can reach the path along that direction so have.

In addition, in the above description, illustrated that the Presentation Function that the path is arrived distance etc. is attached to the situation in the guiding device shown in the example 1, but also can be applicable to the guiding device of other form to have the effect same with above-mentioned example 4.

In addition, in above-mentioned example 4, imagination is carried out the path and is arrived program that distance detection uses and be stored in advance among the ROM62 in the control module 58, but also all or part of of this program can be deposited in the external memory medias such as CD-ROM, as required, utilize regenerating unit it to be read, be used for arriving the path arrival distance detection that distance detector 22 carries out by the path from this external memory media.By such processing, change program easily, can easily carry out the replacing or the edition upgrading of out of order part.

Example 5

In addition, in this example 4, show and arrive the distance in the path that distance detector 22 detects and direction by the path and be presented at situation on the display 16, but also can report to the user with acoustic information with arriving.

Figure 19 is the block diagram of functional structure of the guiding device of the such example of the present invention 5 of expression, and the part suitable with the each several part of example 4 is marked with the symbol identical with Figure 16, and its explanation is omitted.Among the figure, the 23rd, the acoustic information maker, but the parts of representing with symbol 17 among following situation and Figure 16 are different, promptly in the acoustic information storer that install inside, also storing and comprising with acoustic notifications to the word of the information of usefulness such as the distance in the path that sets and direction or phrase etc. as the sound waveform data, when arriving distance detector 22 and detect, select the sound waveform data corresponding and carry out output to voice output device 18 with it to the distance in path and direction by the path.

Figure 20 is illustrated in to carry out the path in the acoustic information maker 23 when arriving the acoustic notifications of distance etc., the key diagram of one of a part of information of the travel direction of moving body being selected according to the direction in path example.Among the figure, the 431st, expression is with respect to the path direction of the travel direction of moving body, and the 432nd, the partial information corresponding with this path direction 431.In addition, Figure 21 is one of the navigation information example of voice output device 18 is exported in expression by acoustic information maker 23 a key diagram, among the figure, the 433rd, the path arrives one of navigation information of distance report usefulness example, and it is according to making according to partial information 432 grades of selecting with respect to the path direction of the travel direction of moving body.

Next illustrates working condition.

Here, Figure 22 is the process flow diagram of treatment scheme of the guiding device of this example 5 of expression.At first the situation with example 4 is the same, in step ST60, by the present position (C1) of present position detecting device 12 detection moving bodys, in step ST61, judges whether directly this processing to be finished in the time of on the path on present path.In the time of not on the path, in step ST62, carry out the detection of the near point (K1) on the path, in step ST63, detect the distance (L1) of the near point (K1) on present position (C1) and the path.

After this in step ST64, detect present position from moving body near the path direction (RD1) this present position.Secondly in step ST65, carry out the comparison of the travel direction of the path direction (RD1) of this detection and moving body, from partial information shown in Figure 20, select the acoustic information (M1) of correspondence.Promptly, travel direction with respect to moving body, if path direction is a travel direction, then select " parallel ",, then select " driving in the wrong direction " if direction is opposite, if to the right, then select " extending " to the right, if left, then select such partial information such as " extending " left as acoustic information (M1).

Secondly in step ST66, judge whether to be directed to and the identical situation of situation that determines by the present position (C1) of above-mentioned moving body, near point (K1), near so far the present position of distance (L1), moving body path direction (RD1) and selected acoustic information (M1) on the path.Its result if finished the guiding of this situation, then directly finishes processing.On the other hand, if also do not finish the guiding of this situation, then in step ST67, carry out acoustic notifications about the near point (K1) on above-mentioned present position (C1), the path, distance (L1), path direction (RD1) and acoustic information (M1).Promptly, according to the near point (K1) on above-mentioned present position (C1), the path, distance (L1), path direction (RD1) and acoustic information (M1), make the navigation information 433 of " about 100m right back is a path direction " shown in Figure 21, " about 100m the place ahead; extend in the path ", " left in path approximately parallel 30m " etc. left, and by voice output device 18 with its output.

Secondly in step ST68, the guiding by the situation of the near point (K1) on these present positions (C1), the path, distance (L1), path direction (RD1) and acoustic information (M1) decision has been carried out in storage.After, carry out above processing repeatedly, travel till on the path until moving body.

Like this, if adopt this example 5, even then since the present position of moving body not on the path, also can use certain direction and the distance in acoustic notifications path, can not know towards which direction running how long distance just can arrive on the path so do not see display frame yet, the user need not leave the place ahead with notice in driving procedure, have the effect of the safer driving of energy.

In addition, in the above description, the situation that will be attached to the function that the acoustic notifications path arrives distance etc. in the guiding device shown in the example 4 has been described, but also can be applicable to the guiding device of other form to have the effect same with above-mentioned example 5.

Example 6

In addition, in above-mentioned example 4, at moving body not under the situation of travelling on the path of setting by path setting device 13, which how long promptly enable to know towards direction running apart from the path that setting is just arranged, but can not show the road that arrives this path, be difficult to know how just can find the path that sets.This example 6 can show from the present position of moving body exactly to the example of the peripheral path in the path that sets.

Figure 23 is the block diagram of functional structure of the guiding device of expression example 6 of the present invention, and the part suitable with the each several part of example 4 is marked with the symbol identical with Figure 16, and its explanation is omitted.Among the figure, the 24th, the peripheral path searcher is used for from map information memory 11 peripheral path that retrieval in the map data stored will couple together by the present position of present position detecting device 12 detected moving bodys and the path of being set by path setting device 13.

Figure 24 is a key diagram of representing to be displayed on by the peripheral path that peripheral path searcher 24 retrieves the demonstration example on the display 16, among the figure, and the 361st, the present position of moving body, the 362nd, near the path the present position 361 of moving body.The 363rd, the near point on the path of the position that the present position 361 apart from moving body of expression on the path 362 is nearest, the 364th, the peripheral path of the near point 363 from present position 361 to this path of moving body.

Next illustrates working condition.

Here, Figure 25 is the process flow diagram of treatment scheme of the guiding device of this example 6 of expression.At first in step ST70, detect the present position (C1) of moving body by present position detecting device 12.Secondly in step ST71, judge that detected present position (C1) whether on the present path of being set by path setting device 13, directly finishes this processing in the time of on the path.On the other hand, present position (C1) enters step ST72 not on the path of setting the time, detects on the path apart from the near point (K1) on present position (C1) nearest path.In addition, so far this handles identical with the situation of example 4.

Next enters step ST73, peripheral path searcher 24 is according to the map datum that is read in by map information memory 11, and retrieval is connecting the peripheral path (W1) between the near point (K1) on the nearest path in the present position (C1) of detected moving body and the present position apart from this moving body (C1) on the path.Secondly in step ST74, as shown in figure 24, according to the near point (K1) on above-mentioned present position (C1), the path, peripheral path (W1), will be presented on the display 16 with the present position 361 of moving body, near this present position 361 path 362 and the near point 363 on the path on this path 362 from the peripheral path 364 of the near point on present position 361 to the path 363.After this, step ST70 is returned in processing, carry out above processing repeatedly, till the present position of moving body is got back on the path.

In addition, when on display 16, showing,, the same with the situation of example 4 about near path 362 and the peripheral path 364 the present position 361 of moving body, from map datum, take out this part, with quantification arithmetical unit 15 it is quantified as simple arrow-shaped and shows.

Like this, if adopt this example 6, even then moving body is under the situation beyond the path that sets, also can with simple graphic presentation from the present position peripheral path to the path that sets, even do not show road-map, also can easily know the effect that how just can find the path so have.

In addition, in the above description, the Presentation Function that the peripheral path in the near path that sets has been described is attached to the situation in the guiding device shown in the example 1, but also can be applicable to the guiding device of other form, has the effect same with above-mentioned example 6.

In addition, in above-mentioned example 6, the program that imagination retrieval is used from present position to the peripheral path in the path that sets is stored in the ROM62 in the control module 58 in advance, but also all or part of of this program can be deposited in the external memory medias such as CD-ROM, as required, utilize regenerating unit it to be read, be used for the retrieval of the peripheral path that undertaken by peripheral path searcher 24 from this external memory media.By such processing, change program easily, can easily carry out the replacing or the edition upgrading of out of order part.

Example 7
