Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a navigation device for displaying a running track on a map.

[0002]

2. Description of the Related Art In a conventional navigation device, a map around the position of an installed vehicle is displayed on a monitor, and the position where the vehicle is traveling is displayed on the map. At the same time, there is a navigation device that displays on the map so that the traveling path of the automobile, that is, the route along which the automobile has traveled can be recognized.

FIG. 7 is a diagram showing an example of a conventional vehicle navigation system of this type in which the traveling locus of a vehicle mounted on the vehicle is displayed on a map on a display screen 70 of a monitor. Figure 7
In FIG. 7, reference numeral 71 is a vehicle position mark indicating the traveling vehicle, and reference numeral 72 is a trajectory mark for indicating a traveling trajectory of the vehicle. The own vehicle position mark 71 is displayed as if traveling on the road 73, and the plurality of locus marks 72 are displayed along the road 73 followed by the own vehicle position mark 71. As a result, the car is on the road 73
You can recognize that you have been running over.

As described above, the user can recognize the current location of the automobile in which he / she is riding and the route on which he / she has traveled by looking at the map as shown in FIG. 7 displayed on the monitor. Then, after the vehicle reaches the destination and finishes traveling, there is a case where the user wants to see a traveling locus on a map which is not displayed on the monitor at that time, that is, a map which is traced from the destination side to the departure side. . In that case, the cursor key or the like of the navigation device is manually operated to scroll the screen of the monitor to display a map of a desired area and follow the traveling locus.

[0005]

However, in the conventional navigation device as described above, even if the user sees the traveling locus displayed on the map, he or she can recognize the specific traveling state. I couldn't do that. For example, in the conventional navigation device, after the traveling is completed, the user can confirm the traveling locus by a method of following the locus by scrolling, but a predetermined mark indicating the car is displayed along the traveling locus on the map. It was not possible to reproduce the running by moving it as if it were actually running.

Further, in the conventional navigation apparatus, it is not possible to reproduce a series of traveling processes from the starting point to the arriving point on the map of the monitor as if the vehicle was actually traveling. For example, an automobile does not always continue to travel at a constant speed on a traveling locus, but the speed may change depending on traffic conditions, and sometimes the vehicle may stop. However, in the conventional navigation device, it is not possible to reproduce and display even such a changing running state,
It simply displayed as a locus the road on which it was traveling. It is desirable for the user to be able to recognize not only the traveling locus but also the traveling condition such as the degree of congestion on each road or the place where he / she stopped in on the way for later traveling. Due to such circumstances, a need arises for a navigation device that can reproduce the actual traveling process of a car on a map. An object of the present invention is to provide a navigation device capable of recognizing a moving state of a moving body that changes every moment along a moving route.

[0007]

In order to solve the above problems and achieve the object, the navigation device of the present invention is constructed as follows. (1) The navigation device of the present invention is based on the movement of the mobile body, the map information storage means for storing the map information, the map display means for displaying the map based on the map information read from the map information storage means. It is composed of information storage means for storing the position information on the map, and control means for reproducing and displaying the moving state of the moving body on the map based on the position information stored in the information storage means. . (2) The navigation device of the present invention is based on map information storage means for storing map information, map display means for displaying a map based on the map information read from the map information storage means, and movement of a moving body. Information storage means for storing position information on the map and speed information corresponding to the position information, and a reproduction state of the moving state of the moving body on the map based on the position information stored in the information storage means. And a control means for changing the moving state of the moving body based on the speed information. (3) The navigation device of the present invention is the device according to (1) or (2) above, and the control means is the map of the moving body within a preset range of the moving route of the moving body. Reproduce the above display.

[0008]

As a result of taking the above-mentioned measures (1) to (3), the following effects will occur. (1) The navigation device of the present invention stores the position information on the map based on the movement of the moving body and reproduces and displays the moving state of the moving body on the map based on the position information. The route that has moved can be recognized, and the transition of the movement state can be recognized along the route. (2) The navigation device of the present invention stores the position information on the map based on the movement of the moving body and the speed information corresponding to the position information, and changes the moving state of the moving body based on the information. Since the reproduction is displayed, the user can recognize the route that the user has moved and the transition of the moving speed along the route. (3) Since the navigation device of the present invention reproduces and displays in a preset range of the moving route of the moving body, the user can specify a desired range of the entire moving route so that The route can be recognized, and the transition of the movement state within the range can be recognized along the route.

3, "Item No. 4" time data 44, "Item No. 5" running speed data 45, "Item No. 6" average speed data 46
Consists of The latitude data 41 is the latitude information of the current location that the CPU 9 receives from the GPS block 2, and the longitude data 4
Similarly, 2 is the longitude information of the current location which the CPU 9 receives from the GPS block 2. The date data 43 is the date data that the CPU 9 acquires from the timer unit 14, and the time data 44 is also the time data that the CPU 9 acquires from the timer unit 14. The traveling speed data 45 is data on the traveling speed of the vehicle received by the CPU 9 from the GPS block 2. The average hourly speed data 46 is data of the average hourly speed calculated based on some latest data among the plurality of traveling hourly speed data 45 stored in the RAM 8.
The data of each item of the traveling locus data having these configurations is detected at every set time stored in the ROM 7
It is stored in AM8.

Next, the operation of the navigation device configured as described above will be described based on the flowcharts shown in FIGS. 4 and 5. Note that FIG. 4 shows an operation procedure in the navigation device while the vehicle actually starts and ends traveling, and FIG. 5 shows an operation procedure in which the traveling is reproduced and displayed based on the traveling locus data stored in the navigation device. Is shown.

First, in step S1, the CPU 9 receives the latitude and longitude data of the current position, that is, the position data from the GPS block 2, and in step S2, the map area (hereinafter referred to as the map area) to be developed in the video RAM 11 based on the latitude and longitude data. Calculate the developed map area). Next, in step S3, when the calculated expanded map area is different from the expanded map area already expanded in the video RAM 11, if it is necessary to change the expanded map area, the CPU 9 determines in step S4 the calculated expanded map area. Map data such as road data and place name data is read from the CD-ROM of the CD block 5 based on the latitude and longitude data in the area.
Then, a map is newly developed in the video RAM 11 based on these data, and the map information near the present location in the developed map is sent to the monitor block 6 as a video signal via the graphic controller 12. As a result, the road map near the present location is displayed on the display screen of the monitor block 6. Also, the above step S3
If it is not necessary to change the item, the expanded map area of the video RAM 11 is not changed.

After that, in step S5, the CPU 9 refers to the timer unit 13, and each time it detects that the set time (for example, 5 seconds) stored in the ROM 7 has elapsed, in step S6, the running shown in FIG. 3 is performed. Data corresponding to each item of the trajectory data is stored in the RAM 8. This RAM8 here
The latitude data 41 and the longitude data 42 of the traveling locus data stored in are the data received from the GPS block 2 by the CPU 9 as described above. Date data 43
The time data 44 is the data detected by the CPU 9 from the timer unit 14 as described above. The traveling speed data 45 is also data received from the GPS block 2, and the average speed data 46 is data indicating the average value of a predetermined number of the latest traveling speed data 45 (for example, the five latest data) stored in the RAM 8. Is. The average hourly speed data 46 is calculated and stored at any time by the CPU 9 because it is difficult to know the accurate traveling state only by the traveling hourly speed data 45. The traveling speed data 45 may be calculated and stored when the CPU 9 calls the traveling speed data 45 when performing a reproduction display operation described later.

Unless the CPU 9 detects in step S5 that the set time has elapsed, the operations in steps S1 to S4 are repeated. Next, an operation procedure in the case where the automobile arrives at the destination, stops traveling, and performs the reproduction display operation will be described. First, in step S7, the CPU
9 sets the range of the traveling locus to be reproduced. Here, the range of the traveling locus is designated by a user referring to a map on the display screen and performing a cursor operation or the like, or by a user operating the TIMER key 37 of the remote control unit 20. This is the range traveled between the start time and the stop time.

Then, in step S8, when the CPU 9 detects that the user has operated the REPLAY key 36 of the remote control unit 20, the CPU 9 starts the reproduction traveling. First, in step S9, the CPU 9 displays the monitor block 6 based on the oldest latitude data 41 and longitude data 42 in the range of the traveling locus designated by the user out of all the traveling locus data stored in the RAM 8. A corresponding map is displayed on the screen and a reproduction mark is displayed on the map. Here, when the map area on the display screen of the monitor block 6 where the reproduction mark is to be displayed is not included in the expanded map area expanded in the video RAM 11, it is necessary to change the expanded map area in the video RAM 11. ,
As shown in step S4, an appropriate map is developed at any time, and corresponding map information in the developed map is sent to the monitor block 6 as a video signal via the graphic controller 12. Then, the information of the reproduction mark indicating the car is sent to the monitor block 6 as a video signal via the graphic controller 12 and corresponds to the latitude data 41 and the longitude data 42 on the road map displayed on the display screen of the monitor block 6. The reproduction mark is displayed at the position where

Thereafter, the CPU 9 sequentially reads the latitude data 41 and the longitude data 42 in each traveling locus data within the range of the traveling locus in the order in which they are stored, and displays a reproduction mark at a corresponding position on the road map. The operation of erasing the reproduction mark displayed before that is continuously performed. In this way, the reproduction mark is displayed and erased continuously within the range of the traveling locus, so that the reproduction mark indicating the vehicle moves as if it is actually traveling on the road map.

Here, the running vehicle does not always continue to run at a constant speed, but the speed changes and sometimes stops. In order to display such a state with reality, in step S10, the CPU 9 refers to the traveling speed data 45 or the average speed data 46 of the traveling locus data corresponding to the reproduction marks at the present time point and the next time point, and between these reproduction marks. Then, the pseudo reproduction mark is continuously displayed and erased at shorter time intervals.

For example, the position indicated by certain latitude data 41 and longitude data 42 stored in the RAM 8 (hereinafter referred to as the first
If the traveling speed data 45 at the position (hereinafter referred to as the second position) indicated by the latitude data 41 and the longitude data 42 subsequent thereto is faster than the traveling speed data 45 at that position, that is, during that period. When the vehicle is accelerating, the pseudo reproduction mark is continuously displayed and erased so as to move while accelerating between the first position and the second position on the road map. . In particular,
The interval at which the pseudo reproduction mark is displayed is widened. Also, the traveling speed data 4 at the first position
When the traveling speed data 45 at the second position subsequent to that of No. 5 is slower, that is, when the vehicle is decelerating in the meantime, the first position and the second position on the road map. The pseudo reproduction mark is continuously displayed and erased so as to move while decelerating between the position and the position. Specifically, the display interval of the pseudo reproduction mark is made narrower.

When the traveling speed data 45 at the first position and the traveling speed data 45 at the second position have the same speed, the first position and the second position on the road map are the same. The pseudo reproduction mark is continuously displayed and erased as if it were moving at a constant speed between the position and the position. If the first position and the second position are the same position, that is, if the first position and the second position have the same latitude data 41 and longitude data 42, the vehicle Indicates that the vehicle was stopped at that position, and since the traveling hour speed data 45 in those traveling locus data are both “0” per hour, the reproduction mark is displayed at the same position and does not move.

By such an operation, for example, when a car equipped with the navigation device is traveling at a high speed on a road with a low traffic volume, the reproduction mark moves quickly in that section on the map, and, for example, the car. If is slowing down on a congested road, the reproduction mark will move slowly in that section of the map. Further, the pseudo reproduction mark moves while accelerating and decelerating according to the change in the speed of the automobile. Further, when the vehicle stops at a certain place for a break or the like, the reproduction mark for the time corresponding to the stop time also continues to stop. In the reproduction display operation, the speed at which the reproduction mark moves on the map on the display screen, or the time during which the reproduction mark is stopped, allows the entire reproduction traveling to be completed in a short time (for example, when the actual total traveling time is 5 hours). , And the total reproduction running time is 30 seconds).

Then, in step S11, the above step S
When the range of the traveling locus set in 7 is exceeded, that is, when the area on the map designated by the user or the stop time designated by the user has passed, the CPU 9 ends the reproduction display operation. Here, the operations of steps S9 and S10 are continued unless the range of the set traveling locus is exceeded.

FIG. 6 is a diagram showing an example of the display screen 60 of the monitor block 6 when the running state is reproduced and displayed as described above. In FIG. 6, reference numeral 61 is a reproduction mark, and the reproduction mark 61 represents an automobile equipped with the navigation device. The reproduction mark 61 indicates the range of the traveling locus designated by the user (for example, the entire course driven on that day, or the section from one place designated to another place on the map, or the total time spent traveling). From a certain time to a certain time), display screen 6
Based on the above traveling locus data when the vehicle actually travels on the map of 0, it changes every moment and travels again. At this time, a reproduction mark 61 (having the same meaning as the own vehicle position mark 71 shown in FIG. 7) is used in order to make it easy to see where on the map the vehicle is traveling. Here, the map automatically scrolls as in the navigation operation during actual traveling.

Further, in addition to the latitude data 41 and the longitude data 42 as traveling locus data in the RAM 8, the traveling hour speed data 45 and the average hourly speed data 46 at that time are also stored together, so that a more realistic reproduction is possible (reproduction mark 61). The speed of moving and the scrolling speed of the map are set according to the actual running speed). Further, in FIG. 6, reference numeral 62 is a time display section, and this time display section 62 is based on the time data 44 of the traveling locus data and the reproduction mark 61.
The time at which the car was actually traveling is displayed at a location on the map where is reproduced. Reference numeral 63 denotes a speed display unit. The speed display unit 63 uses the traveling hour speed data 45 of the traveling locus data and the average hourly speed data to display the location where the reproduction mark 61 is reproduced on the map. Displays the hourly speed when actually driving. The time display unit 62 can display not only the time but also the date based on the date data 43 of the traveling locus data, and can also display the time elapsed from the start of the reproduction traveling.
Further, the speed display unit 63 can display not only hourly speed but also minute speed, second speed, and the like.

According to the embodiment as described above, the RAM 8
Based on the traveling locus data stored in, it is possible to recreate the actual traveling course and the traveling according to the traveling state by changing every moment. Therefore, for example, what course the drive on a certain day (or from a certain point to another) has followed can be reproduced after the end of the driving on that day or at a later date. Also, the speed reproduced according to the running speed changes, and the speed is displayed numerically, and the time when the vehicle travels at each location is also displayed. Therefore, it is possible to recognize the traffic condition such as which part is crowded and which part can be smoothly driven from the speed condition, and the traffic condition corresponding to the time zone can be recognized from the time information. Therefore, the user can refer to and use the information when driving the same course next time or when teaching directions and traffic conditions to a person who does not know the course. Further, the user can confirm the place where he / she stopped and stopped, for example. Also, by automatically scrolling the map as the vehicle is traveling based on the traveling locus data, the traveling course and traveling state can be reproduced on the screen, so that the user can manually monitor the monitor like a conventional navigation device. There is no need to scroll the screen to display the map of the desired area and follow the running trajectory.

The present invention is not limited to the above-mentioned embodiments, and can be carried out by appropriately modifying it within the scope of the invention.
For example, in the above embodiment, the position of the present location is determined by GPS using an artificial satellite, but an azimuth sensor (moving direction detecting means) and a distance sensor (moving amount detecting means)
The relative locus may be obtained by obtaining the traveling locus by. This method is called dead reckoning. Further, the position on the map may be obtained by comparing the traveling locus obtained by this dead reckoning and the road shape of the map and determining the passing road. This method is called map matching. You may combine this map matching and GPS. The moving direction data may be detected by the azimuth sensor and stored in the RAM 8 as one item in the traveling locus data shown in FIG. 3 so as to be utilized in the reproduction display, which makes the reproduction with more reality. Display can be done.
