Description

  The present invention relates to a route output device that outputs a more appropriate route.

  In recent years, some route output devices such as navigation systems can search for and select a back road (a road that bypasses a main road or the like). Such a search for the back road in the route output device is realized by performing a route search by temporarily changing the cost set for the links constituting the map data. In other words, links with relatively high costs such as links corresponding to side roads and side roads are temporarily set at a cost equivalent to or lower than that of main road links such as national and prefectural roads. This is realized by performing a route search.

Further, the required time when the searched route is traveled and its route information are stored in the travel history storage means, and the stored required time is compared with the expected required time of the newly searched route. In addition, a route output device that displays a route with a shorter required time on a display unit as a recommended route has also been proposed (for example, Patent Document 1).
JP 2002-310969 A

However, for side roads and side roads that constitute back roads, traffic information from VICS ( registered trademark, Vehicle Information and Communication System) is generally not available. There was a risk that side roads, side roads, and the like were congested and would take more time (the former route output device described above).

  The latter route output device described above stores the required time and its route information in the travel history storage means only when the route searched as the recommended route is traveled. Even if the route that has not been made is traveled, the required time and route information are not stored in the travel history storage means. That is, it is difficult for the user's traffic performance to be reflected in the subsequent route guidance.

  The present invention has been considered in view of such problems, and it is an object of the present invention to provide a route output device or the like that allows a user to effectively use a back road or the like.

The route output device of the present invention , which has been made to solve the above problems, includes position information acquisition means, speed information acquisition means, storage means, first control means, and second control means. The position information acquisition means acquires position information for specifying its own position, the speed information acquisition means acquires speed information for specifying its own moving speed, and the storage means stores the information. In addition, the first control means obtains a total time by summing times that are either lower than or higher than the predetermined moving speed on the predetermined route based on the speed information acquired by the speed information acquisition means. The ratio of the total time occupying the process time is calculated, and the calculated ratio is stored in the storage unit together with the route information obtained based on the position information acquired by the position information acquisition unit. The second control means reads and outputs at least one piece of route information stored in the storage means. The “route information” here is information that can guide at least a predetermined route based on this route information. Specifically, for example, link information from a departure point to a destination point can be considered.

  Accordingly, the route information read by the second control means is used for route guidance from the next time on, so that the route actually taken by the user is guided. That is, route information such as a back road that is selected and passed by the user's judgment is stored regardless of whether the user passes the route presented by the route guidance device or the like. Then, by utilizing the stored route information, the time to arrival at the destination is shortened, and driving comfort is improved. In addition, since the ratio is calculated by the method described above and stored in the storage unit together with the route information, the route information is used in consideration of the ratio, and the route that can avoid a long traffic jam state is passed. In this case, driving comfort is particularly improved.

By the way, the specific operation of the first control means is that when the ratio and route information are stored in the storage means, the route that is the same starting point and destination as the starting point and destination of the route information scheduled to be stored this time. Information may be searched from the route information stored in the storage means, and the ratio stored in the storage means corresponding to the found route information may be compared with the ratio stored this time. Then, the first control means may determine whether to store the ratio and route information in the storage means based on the comparison result, and execute processing according to the determination result. (Claims 1 and 5 ). In addition, when the applicable route information is not found in the route information stored in the storage unit, information to be stored this time may be stored in the storage unit unconditionally.

  With such a route output device, only the information corresponding to the low (or high) ratio described above is stored in the storage means for the route information that is the same starting point and destination. Use of the memorable area of the means can be minimized. In addition, when the route information is read out from the storage unit, the route information with the lowest rate (or the highest rate) among the information stored in the storage unit can be read out only by considering only the route information. The processing load at the time is reduced.

By the way, the “predetermined movement speed” used when the first control means calculates the above-described ratio may be, for example, 0 km / h (claim 6 ).
In such a case, the above-mentioned ratio means “the ratio of the total time during which the moving speed was 0 km / h in the total travel time”, which indicates how much the vehicle has stopped in terms of time. It will be. For this reason, by taking this ratio into consideration, the path output device can output information on a path with a small percentage of time during which it has stopped (that is, a path with a short stop time due to traffic jams, signals, etc.).

Further, the “predetermined moving speed” used when the first control means calculates the above-described ratio may be, for example, a speed that is half the average moving speed in the total stroke of the predetermined route (claims 2 and 7 ). .
In such a case, the above-mentioned ratio means “the ratio of the total time that the moving speed is less than (or more than half) the moving speed that is half the average moving speed in the total travel time”. It represents how much it was at a relatively low speed (or a relatively high speed) from the viewpoint. For this reason, by taking this ratio into consideration, information on a route that travels at a relatively low speed with a small proportion of time (that is, a route that has a low stop time due to traffic jams, signals, etc. and a low speed travel time) is output to the route output device Can be output.

By the way, normally, the route output device searches for a recommended route from a predetermined position to a predetermined destination based on the information acquired by the information acquisition means for acquiring information necessary for searching for the route, and the searched route information Is often provided (function realized by the third control means). Therefore, it is preferable that the route information output by this function and the route information output by the second control unit described above are finally output alternatively from the route output device. In other words, the route output device is configured such that one of the second control unit and the third control unit is based on the route output instruction operation that is received by the receiving unit that receives the operation from the user and instructs to output the route. It is good to function (Claims 3, 4, 8, 9).

Further, the first control means may function when the accepting means accepts a new calculation instruction operation instructing to newly calculate the ratio for the predetermined route (claim). Item 3, 4, 10).
If it becomes like this, the ratio and the route information described above can be stored in the storage means according to the will of the user. In other words, for example, back road registration can be performed at the user's will.

In addition, it may be proposed to store the above-described ratio and route information in the storage unit for the user. Specifically, for example, as described in claims 3 and 11, the fourth control means for controlling the notifying means for notifying the user of the information determines whether or not the current time is in a predetermined time zone. When it is determined that the current time is in a predetermined time zone, it is preferable that information for causing the user to perform the above-described new calculation instruction operation is notified to the notification means.

If this is the case, for example, the above-mentioned proposal is made at the time of morning and evening rush, and if the user performs a new calculation instruction operation on the proposal, the back road registration at the time of rush is performed. In other words, if the back road is registered during a rush hour when the degree of occurrence of traffic congestion is high, the back road effective in the time zone that the user most wants to go through the back road is stored in the storage means. Therefore, the value of the information stored in the storage unit can be improved.

Further, as described in claims 4 and 12, the fifth control means for controlling the notifying means for notifying the user of the information determines whether or not the information acquired by the information acquiring means has been updated, and acquires the information. When it is determined that the information acquired by the means has been updated, the notification means may be notified of information for causing the user to perform a new calculation instruction operation.

  If this is the case, for example, when a DVD-ROM storing road information is exchanged, route information based on the new road information is stored in the storage means. The accuracy and value of information to be improved.

By the way, the storage means generally has a limit on the amount of information that can be stored. Therefore, as described in claim 13 , when the first control unit stores the route information in the storage unit, the first control unit may store the time information corresponding to the route information. . The route output device further determines whether the route information is valid based on the time information stored in the storage unit at a predetermined timing, and determines that the route information is not valid. It is preferable that sixth control means for deleting the route information corresponding to the time information from the storage means is provided.

  If this is the case, the amount of information stored in the storage means can be effectively controlled, and the limit of the amount of information that can be stored in the storage means has been reached, so that new information cannot be stored. Can be prevented.

In addition , a program that functions as the first control unit in the route output device according to any one of claims 1 to 13 may be executed by a computer built in the route output device. In this case, for example, the program is recorded on a computer-readable recording medium such as a flexible disk, a magneto-optical disk, a CD-ROM, a hard disk, a ROM, and a RAM, and the program is stored in the computer as necessary. By loading and starting, the computer can function as the first control means of the path output device. Further, since the program can be distributed using a network or the like, it is easy to improve the function of the route output device.

Further , a program that functions as the second control unit in the route output device according to any one of claims 1 to 13 may be executed by a computer built in the route output device. Even if it is in this way, the same effect is produced.

A program that functions as the fourth control means according to claims 3 and 11 , the fifth control means according to claims 4 and 12 , and the sixth control means according to claim 13 is routed. The computer may be executed by a built-in output device.

  The position detector 21 receives a radio wave from a GPS (Global Positioning System) artificial satellite via a GPS antenna (not shown) and outputs a received signal, and a magnitude of rotational motion applied to the vehicle. A gyroscope 21b for detecting the distance, a distance sensor 21c for detecting a distance traveled from the longitudinal acceleration of the vehicle, and the like, and a geomagnetic sensor 21d for detecting the traveling direction from the geomagnetism. Then, based on the output signals from these sensors 21a to 21d, the control unit 29 calculates the position, direction, speed, etc. of the vehicle. Although there are various methods for obtaining the current position based on the output signal from the GPS receiver 21a, either a single positioning method or a relative positioning method may be used.

  The operation switch group 22 includes a touch panel configured integrally with the display surface of the display unit 26, mechanical key switches provided around the display unit 26, and the like. The touch panel and the display unit 26 are laminated and integrated. There are various types of touch panels such as a pressure-sensitive method, an electromagnetic induction method, a capacitance method, or a combination of these methods. It may be used.

The external communication device 24 acquires accident information, traffic jam information, and the like from an information center of VICS (registered trademark) via an optical beacon or a radio beacon installed on the roadside.
The map data input device 25 is a device for inputting various data stored in a map data storage medium (not shown) (for example, a hard disk or a DVD-ROM). Map data storage media include map data (node data, link data, cost data, background data, road data, name data, mark data, intersection data, facility data, etc.), voice data for guidance, voice recognition data, etc. Is remembered. Instead of inputting these data from the map data storage medium, these data may be input via a communication network.

  The display unit 26 is a color display device such as a liquid crystal display, an organic EL display, or a CRT, and any of them may be used. The display screen of the display unit 26 includes a mark indicating the current location identified from the current position of the vehicle detected by the position detector 21 and the map data input from the map data input device 25, a guidance route to the destination, and a name. Additional data such as landmarks and various facility marks can be displayed in an overlapping manner. Also, facility guides can be displayed.

The microphone 28 outputs an electric signal (voice signal) based on the inputted voice to the control unit 29 when the user inputs (speaks) voice. The user can operate the navigation device 20 by inputting various sounds to the microphone 28.

  The control unit 29 is configured around a well-known microcomputer including a CPU, ROM, RAM, SRAM, I / O, and a bus line connecting these components, and is based on a program stored in the ROM and RAM. Various processes. For example, the current position of the vehicle is calculated as a set of coordinates and traveling directions based on each detection signal from the position detector 21, and a map or the like near the current position read via the map data input device 25 is displayed on the display unit 26. The optimal route from the current position to the destination is calculated based on the processing to be performed, the map data stored in the map data input device 25, and the destination set according to the operation of the operation switch group 22 or the remote controller 23a. A route calculation process, a route guidance process for guiding the route by displaying the calculated route on the display unit 26 or outputting it as a voice to the voice output unit 27, and the like are executed.

  In addition, in the storage area of the SRAM provided in the control unit 29, there is a table area for storing information related to the back road. The table defined in this area will be described with reference to the table schematic diagram of FIG.

  The back road table 61 shown in FIG. 2 is a table for accumulating information recorded when traveling on the back road. The record of the backside table 61 includes a record ID 61a that is an item of the record identifier, a recording date and time 61b that is an item of the date and time when the record is recorded, a departure point node 61c that is an item of the node number of the departure point of the travel route, The arrival point node 61d, which is an item of the node number of the arrival point of the travel route, the congestion jam rate 61e, which is a ratio item indicating how much congestion has occurred, and the route, which is an item of the link string constituting the travel route Information 61f.

The record recorded in the backside table 61 is generated and inserted in a route recording process described later.
Next, among the processes executed by the control unit 29, a path calculation process, a path recording process, and a backside table deletion process, which are processes characteristic of the navigation device 20 of the present embodiment, will be described below. In addition, description is abbreviate | omitted about general processes, such as a route guidance process, which the conventional navigation apparatus performs.

(1) Route Calculation Processing First, route calculation processing will be described using the flowchart of FIG. The route calculation process is a process in which the control unit 29 starts executing when a user inputs a destination point by operating the operation switch group 22 or the remote controller 23a.

  When the control unit 29 starts executing the route calculation process, first, a node near the current point (departure point) calculated based on a signal output from the position detector 21 and a node near the destination point input by the user It is determined whether or not a record having the same data exists in the back street table 61 (S110). This determination is made by referring to the data of the departure point node 61c and the data of the arrival point node 61d in the record of the back road table 61, respectively. Note that instead of the data of the departure point node 61c, the determination may be made by using a node corresponding to any link constituting the data of the item of the route information 61f. That is, the above determination may be satisfied even when there is a departure point in the middle of the route.

  If it is determined in S110 that no record satisfying the condition exists in the backside table 61 (S110: NO), a route search is performed using a route search algorithm such as the Dijkstra method that has been conventionally performed (S120). Then, some of the routes found by performing this route search are displayed as candidate routes, and their outlines are displayed on the display unit 26 (S130). Then, this process (route calculation process) is terminated.

  On the other hand, even when it is determined in S110 that a record satisfying the condition exists in the backside table 61 (S110: YES), a route search is performed using a route search algorithm such as the Dijkstra method that has been conventionally performed (S140). Then, some of the routes found by performing this route search and routes determined by the information of the records found from the back road table 61 (back road routes) are displayed as candidate routes on the display unit 26 (S150). . Then, this process (route calculation process) is terminated.

(2) Route Recording Process Next, the route recording process will be described with reference to the flowchart of FIG. The route recording process is executed by the control unit 29 when any one of the routes displayed on the display unit 26 by the route calculation process described above is selected by the user operating the operation switch group 22 or the remote controller 23a. Is a process of starting. In parallel with this process, a route guidance process for guiding the route selected by the user is started. Description of this route guidance process is omitted.

  When the control unit 29 starts executing the route recording process, first, it is determined whether or not a predetermined time has elapsed since the previous registration of the back road to the target destination (S210). This determination is based on the node and user near the current point (departure point) calculated based on the signal output from the position detector 21 used in the route calculation process executed prior to the execution of the route recording process. A record having the same data as that of the node near the destination point input by searching is searched from the backside table 61, and the data of the item of the record date 61b in the record found by the search has passed one month or more compared to the current date. It is to determine whether or not. If the determination result is “one month or more has elapsed”, it is determined that a certain time has elapsed since the last backside registration (S210: YES), and the determination result is “ If the result indicates that “one month or more has not elapsed”, it is determined that a predetermined time has not elapsed since the last backside registration (S210: NO). If no corresponding record is found when the back road table 61 is searched, it is determined that a certain time has elapsed since the last back road registration (S210: YES).

  Here, when it is determined that the predetermined time has not elapsed since the last back road registration (S210: NO), it is determined whether or not the current time is in a predetermined time zone set in advance (S215). . The “predetermined predetermined time zone” is a time zone stored in the control unit 29, and is input by operating the operation switch group 22 or the remote controller 23a by the user. Specifically, traffic time zones such as AM 7:00 to AM 9:00 and PM 5:00 to PM 7:00 are mainly set.

  If it is determined in S215 that the current time is within a predetermined time zone set in advance (S215: YES), the process proceeds to S230 described later. On the other hand, when it is determined that the current time is not a predetermined time zone set in advance (S215: NO), this processing (route recording processing) is terminated.

  In S210 described above, when it is determined that a certain time has passed since the last back road registration (S210: YES), it is determined whether or not the map data has been updated (S220). This determination is based on whether or not the map data input by the map data input device 25 has been updated, that is, if the map data stored in the map data storage medium has been upgraded when the map data is input from the map data storage medium. If the map data is input via the communication network, it is determined whether the version of the map data has been upgraded.

  If it is determined in S220 that the map data has been updated (S220: YES), the user is notified that the map data has been updated (S225), and prompted to newly develop a back road (S230). . Note that these notifications are performed by causing the display unit 26 to display such information in characters or by causing the audio output unit 27 to output audio.

On the other hand, if it is determined in S220 that the map data has not been updated (S220: NO), only a notification that prompts the user to newly develop a back road is performed (S230).
Subsequently, it is determined whether or not an instruction to newly develop a back road is input by the user operating the operation switch group 22 or the remote controller 23a (S235). When an instruction to newly develop a back road is not input (S235: NO), this process (route recording process) is terminated.

  On the other hand, when an instruction to newly develop a back road is input (S235: YES), recording of vehicle traffic information is started (S240). The vehicle traffic information referred to here is link information corresponding to a route through which the vehicle passes and vehicle speed information per second, and is stored in a predetermined temporary storage area in the control unit 29.

  Subsequently, when the vehicle arrives at the destination, the recording of the traffic information of the vehicle is terminated (S245), and the congestion jam rate is calculated (S250). This “congestion jam rate” is calculated based on the information stored in a predetermined temporary storage area in the control unit 29, and the total time that is less than half of the average vehicle speed during the total stroke is obtained. The ratio of the process time is calculated.

  Subsequently, by a node and a user near the current point (departure point) calculated based on the signal output from the position detector 21 used in the route calculation process executed prior to the execution of the route recording process. The record having the same data as the node near the input destination point is searched from the back road table 61, and the jamming rate calculated in S250 is more than the data of the item of the jamming rate 61e in the found record. It is determined whether or not the value is lower (S255). In addition, when the corresponding record is not found when searching the back road table 61, it is determined that the traffic jam rate calculated in S250 is lower (S255: YES).

  In S255, when it is determined that the congestion jamming rate calculated in S250 is lower than that of the record found by searching the back road table 61 (S255: YES), it is stored in the control unit 29. Based on the route information and the jamming rate calculated in S250, a record for storing in the back road table 61 is configured (see FIG. 2), and the record is stored in the back road table 61. Then, this process (route recording process) is terminated.

  On the other hand, if it is determined that the congestion jamming rate calculated in S250 is higher than that of the record found by searching the back road table 61 (S255: NO), this processing (route recording processing) is terminated.

(3) Back road table deletion process Next, the back road table deletion process will be described with reference to the flowchart of FIG. The backside table deletion process is a process in which the control unit 29 starts executing every time a predetermined period (for example, one month) elapses. The “predetermined period” can be changed by the user operating the operation switch group 22 or the remote controller 23a.

  When the control unit 29 starts executing the backside table deletion process, first, the record with the smallest record ID is read from the backside table 61 (S310). Then, it is determined whether or not the reading has failed (S320). If this reading fails, the present process (back road table deletion process) is terminated. On the other hand, if the reading is successful, it is determined whether or not the data of the item of the recording date 61b in the read record is a value that has passed half a year or more from the current date (S330).

  When it is determined that the data of the item of the recording date 61b is a value that has passed more than half a year from the current date (S330: YES), the record is deleted from the backside table 61 (S340), and the next smallest record ID is set. The recorded record is read from the back road table 61 (S350). Then, the process returns to S320 described above.

  On the other hand, if it is determined in S330 that the data of the item of the recording date 61b is not a value that has passed half a year or more from the current date (S330: NO), the record having the next smallest record ID is read from the back table 61 ( S350). Then, the process returns to S320 described above.

[Effect of the embodiment]
Although the configuration and operation of the present embodiment have been described above, according to the navigation device 20 of the present embodiment, the route information of a route with a low traffic jam rate is a back road among routes actually traveled at the user's will. It is stored in the table 61 (S260 in FIG. 4). In the next and subsequent route guidance, if a route to the same destination as the destination designated by the user exists in the backside table 61, the backway is also displayed on the display unit 26 as a guide route that can be selected by the user. (S150 in FIG. 3).

  In other words, regardless of whether the user does not pass the route calculated by the navigation device 20, route information such as a back road that is passed by the user's judgment is stored and utilized. Therefore, a back road or the like that has not been guided in the past is guided, the time to arrival at the destination is shortened, and driving comfort is improved. Further, since the congestion jam rate is calculated by the method described above and stored in the back road table 61 together with the route information, it is possible to travel along a route that can avoid a longer congestion state. In particular, driving comfort is improved.

  Further, when the navigation device 20 newly stores the route information, only the route information with a low traffic congestion rate is stored in the back road table 61. If the traffic information congestion rate of the already stored route information is lower, a new information is stored. The route information is discarded (S255: NO in FIG. 4). For this reason, it is possible to prevent the storage area of the back road table 61 from being compressed. Further, when the route information is read from the back road table 61, only the route information to the corresponding departure place and the destination is considered, and the route information with the lowest traffic jam rate to the destination is taken as the back road. Since the data can be read from the table 61, the processing load on the control unit 29 at the time of reading is reduced.

  In addition, when the current time is in a predetermined time zone or when the map data is updated, the user is prompted to take a new back road (S215 in FIG. 4: YES, S230) If the user follows such a proposal, route information having high utility value is positively stored in the backside table 61.

  Further, the navigation device 20 determines whether or not the information stored in the back road table 61 is stored more than six months ago (S330 in FIG. 5), and is stored more than six months ago. In this case, the information is deleted from the back road table 61 (S340 in FIG. 5). For this reason, it can be prevented that old back road information continues to be accumulated in the back road table 61 and reaches the limit of the amount of information that can be stored in the back road table 61 and new information cannot be stored.

[Other Embodiments]
Hereinafter, other embodiments will be described.
(A) In the above-described embodiment, only the route information with the lowest traffic jam rate for the same starting point and destination point is stored in the back road table 61. However, without considering the traffic jam rate, The route information may be stored in the back road table 61. Alternatively, the route information may be stored by taking into consideration that, for example, only the top three items having a low traffic jam rate are stored in the back road table 61. In this way, a plurality of back roads can be proposed to the user at the time of route guidance, and the range of route selection for the user is expanded.

  (B) In the above-described embodiment, as a method for calculating the congestion jam rate, a method of calculating the total time that was less than half of the average vehicle speed during the total stroke and calculating the ratio of the total to the total stroke time. Although adopted, the method of calculating the jam rate is not limited to this. For example, a calculation method of calculating the total stop time during the total stroke and calculating the ratio of the total to the total stroke time may be used, or the total time that was less than one third of the average vehicle speed during the total stroke. Alternatively, a calculation method may be used in which the ratio of the total to the total process time is calculated.

  (C) In the above embodiment, the back road table deletion process is executed once a month. However, the back road table deletion process may always be executed. In addition, the information stored more than six months ago was deleted, but for example, the information stored more than three months may be deleted or stored more than one year ago Information may be deleted. These values may be set by the user. Further, instead of such a deletion method, the number of times of use of route information may be stored in the backside table 61 and information with a low number of times of use may be deleted.

[Correspondence with terms in claims]
The correspondence between the terms in the above embodiment and the terms described in the claims is shown. The position detector 21 corresponds to position information acquisition means, the distance sensor 21c corresponds to speed information acquisition means, and the control unit 29 includes storage means, first control means, second control means, and third control means. , Corresponding to the fourth control means, the fifth control means and the sixth control means. The map data input device 25 corresponds to information acquisition means, the operation switch group 22 and the remote controller 23 correspond to reception means, and the display unit 26 and the audio output unit 27 correspond to notification means.
