Example 1
Fig. 1 illustrates the major part of the present invention's one example guider.This guider has control circuit 1.This control circuit is controlled whole guider according to the program work that is stored among the ROM 2.
This GPS utilizes the instantaneous synchronization timing of simulation random code as C/A sign indicating number or P sign indicating number in measuring in the delivery time of electric wave, measures the distance between guider and gps satellite.This error is about 90% below 100 meters.As reasons of error, have: the clock error of satellite, the orbit error of satellite, ionosphere delay time error, troposphere delay time error, receiver noise, multipath and SA (preferential validity).
Be illustrated in the reference point (GPS correction station) of having known the position in advance in the electric wave transmission with the FM broadcasting station and go up the signal of the GPS electric wave error of measuring, carry out based on this signal in guider under DGPS (differential Global Positioning System) situation of error correction, measuring error is little of about 1/10 of GPS.And then under the KGPS of carrier phase location mode (motion GPS) situation, measuring error is from several millimeters to several centimetres.But now commercially available guider is main flow with GPS, if do not carry out map match (opening flat 8-35850 communique with reference to the spy), then in fact in moving along highway, sometimes because measuring error and the present position is shown as place beyond the highway.Map match is an object with the highway of (for example, 150 meters in) in the GPS error range, carries out the measured highway and the contrast of present position.For example, carry out the highway on the map and the contrast of motion track, seek consistent highway, be judged as the present position on this highway.
Cartographic information regenerating unit 40 is equipped with medium 41, for example CD-ROM that has write cartographic information, reads cartographic information from medium, supplies to control circuit 1.As cartographic information, have: the title of road map data, highway and place information.As place information, have: the title in area is street name and location information for example.So-called location information is the information of expression locality, comprises as this place: park, main buildings and railway station.In the following description, so-called " the place information of expression present position " means in the title that is illustrated near the area the present position on the map or the title in place.Constitute cartographic information memory storage 4 by cartographic information regenerating unit 40 and medium 41.
In the operation of the usefulness such as setting of the rolling of the display frame of display device 5, the change of engineer's scale, mobile predefined paths, use input media 7.
With reference to the process flow diagram of Fig. 2, the work of above-mentioned example is described.Control circuit 1 carries out map match, check by the detected present position of GPS positioning apparatus be stored in the cartographic information memory storage in map on highway whether consistent (S1).In unanimity situation under, be judged as the present position in unanimity highway on, revise the data of expression present position, make display device show present position (S2) by the present position data representation of having revised.Then, if storing the title (among the S3, being "Yes") of the highway at the place of having revised, present position in cartographic information memory storage 4, then control circuit 1 makes display device 5 show that the literal of expression motorway names is (in the example of diagram, be “ Jing Leaf road "), (S4) as shown in Figure 3.In the example of diagram, literal is presented on the regulation zone of display frame, for example near the right side of picture bottom.
Under the situation of not storing motorway names, (among the S3, be "No"), check within the limits prescribed whether (for example, 1 kilometer in) exists displayable place information (S5).If place information exists, then as shown in Figure 4, show the literal of expression place information.At this moment, as required, additional after the information of place " paying near " (near) printed words.
In the example of Fig. 3, showing such literal on the assigned position of picture: " Bang Ding Postal just office pays near " (near the creek raised path between farm fields post office).
Have again, in the title that is chosen in area or place, show when any, can be chosen in and be nearest person on the map, in addition, also can select based near and popularity this two.
In step S5, if there is not place information, then the title of highway or place information do not show (S7).
In step S1, when the present position be stored in arbitrary highway on the map in the cartographic information memory storage 4 when all inconsistent, control circuit 1 is not revised by the detected present position of GPS positioning apparatus, but it is considered as correct present position, make display device 5 show (S8) same as before as the present position.And, in step S5, as shown in Figure 5, show the place information (S6) of expression present position.At this moment, as required, additional " paying near " such literal.Its result in the example of diagram, shows " creek Ding Gong Garden pays closely " such literal on the assigned position of picture.
Have again, in the above description, " the place information of expression present position " means near the title in the area of representing the present position on the map or the title in place, but, the title that can comprise the area of present position replace near the present position, represent area title, use as the place information of expression present position, in addition, also can replace near the title in the place of present position near the present position, represent place title, use as the place information of expression present position.
In addition, for example the display position of the position of the point of the lower-left of the literal foremost of the text strings in expression place as place information used, still, also can use the display position of other position as the place.
Example 2
Fig. 6 illustrates the major part of another example guider of the present invention.The reference marks identical with Fig. 1 represented identical or corresponding member.
The device of this example is a portable devices, under the situation of operative installations, uses battery 8 as power supply in the travelling of walking or bicycle.This device also has external power source input terminal 9.This device by the power output terminal that is provided with usually on cable (not shown) and the automobile for example cigarette lighter (not shown) be connected.By doing like this, device can utilize external power source and work.
Whether the power supply that uses in 10 pairs of guiders of power detector is supplied with by external power source and is judged, the result of this judgement is supplied to control circuit 1.Whether power detector 10 for example for example is connected with external power source splicing ear 9 being connected with cable of cigarette lighter with power output terminal by detecting, and carries out above-mentioned judgement.
Below, with reference to the process flow diagram of Fig. 7, the work of this example is described.When being judged as employed power supply for the power supply supplied with by external power source (from the power supply of cigarette lighter) (among the S11, being "Yes"), control circuit 1 is judged as guider and is installed on the automobile, carries out map match (S12).And, make the title of the highway that display device 5 shows consistent with the present position.
(among the S11, be not "No") when employed power supply is not external power source, control circuit 1 does not carry out map match (S14), makes display device 5 show the place information (S15) of expression present position.
According to above-mentioned example, when employed power supply was not external power source, control circuit was judged as guider and is not installed on the automobile.For example, when utilizing guider in the travelling of walking or bicycle, compare with the precision of GPS, translational speed is lower.Thereby, be difficult to judge mobile direction.For the calculating of map match, must know moving direction.This is because will the highway on the motion track of guider and the map be compared.Its result, when the travelling of walking or bicycle, correct map match is difficult.Thereby, when power supply is not external power source, do not carry out map match.
When having many highways, in the judgement that utilizes map match, the width of selection broad or the tendency of major highway are arranged.For example, when be installed in guider on the bicycle, bicycle when in the alleyway of national highway, travelling, existing guider has and is judged as the present position tendency consistent with national highway.In this example, owing to the map match of not carrying out under such situation, so do not cause such mistake.
And then, compare with situation about in automobile, using, in walking or bicycle running, use under the situation of guider, the possibility of guider in the place beyond the highway be bigger.When for example guider is in the park, show the title in park and near not showing highway.
The possibility of industrial utilization
As mentioned above, according to the 1st example, the arbitrary highway on present position and map When all inconsistent, show that the place information of expression present position replaces highway and title. Example As, the automobile that guider has been installed sail in the situation in the alleyway that does not have on the map or Automobile is in the parking lot time, and the present position is not on the highway on the map. At this moment, by expression The literal in place also can be known the present position. In addition, by additional " paying near " such literal Can identify clearly, the present position is not the place itself that represented by place information but at it Near.
In addition, the present position is consistent with the highway on the map, still, is not showing the name of highway In the situation about claiming, for example in the nameless situation of highway or at the cartographic information storage device In do not store in the situation of title of highway, shown the place information of present position by literal.
According to the 2nd example, when being used for guider except automobile, for example work as When being used for the travelling of walking or bicycle, can prevent that a present position is presented at highway mistakenly On, the title of the highway of perhaps demonstration mistake.
