  When the presentation route search request is output from the route calculation unit 23 to the vehicle information providing device 3 in step S202, the vehicle information providing device 3 calculates the presented route in the processing procedure (steps S401 to S412) shown in FIG. 6A. This is determined and transmitted to the route calculator 23 of the terminal device 2 (details will be described later with reference to FIG. 6A). Next, proceeding to step S203, the route calculation unit 23 receives the information including the presentation route information, the power consumption information, and the charging via point information transmitted from the vehicle information providing device 3 (from step S412 in FIG. 6A). ). In step S202, when the presented route cannot be determined, the route calculation unit 23 receives planned route information instead of the presented route information.

  Subsequently, the process proceeds to step S204, and the route calculation unit 23 determines whether or not the information on the presented route has been received in step S203. If the route calculation unit 23 determines that the information of the presentation route has been received (step S204 = Yes), the route calculation unit 23 proceeds to step S205. On the other hand, if the route calculation unit 23 determines that the information on the planned route is received instead of the information on the presented route (step S204 = No), the route calculation unit 23 proceeds to step S207.

  If it is determined that the presentation route information has been received, the process proceeds to step S205. In step S205, the route calculation unit 23 obtains the information acquired in step S203 described above (presentation route information, power consumption information, and charging via point). The control command to display the information on the presentation route and the information on the waypoint through charging is output to the display unit 24. In the following step S206, the route calculation unit 23 displays a control command for displaying power consumption information among the information (presentation route information, power consumption information, and charging via point information) acquired in step S203 described above. After outputting to the unit 24, the route providing process is terminated. Thereby, the display shown in FIG. 2A is performed on the display screen.

  On the other hand, if it is determined that the presented route information has not been received, the process proceeds to step S207. In step S207, the route calculation unit 23 obtains the information (plan route information, power consumption information) acquired in step S203 described above. Control information for displaying the information on the planned route and the information on the charging route is output to the display unit 24.

  In the subsequent step S208, the route calculation unit 23 displays a control command for displaying power consumption information among the information (plan route information, power consumption information, and charging via point information) acquired in step S203 described above. After outputting to the unit 24, the route providing process is terminated. Thereby, the display as shown in FIG. 2A is performed on the display screen.

<History accumulation processing>
FIG. 5 is a flowchart showing a subroutine of the history accumulation process (step S30) of FIG. 2B. The history storage process is executed by the travel history storage unit 26 of the vehicle information providing device 3. When the travel history storage unit 26 receives the first travel history information or the second travel history information from the route calculation unit 23, the history storage process is performed. Execute.

  In step S301 in FIG. 5, the travel history storage unit 26 stores the first travel history information or the second travel history information received from the travel history recording unit 19 of the in-vehicle device 1 as travel history information, and ends the history storage process. To do. At that time, the travel history accumulating unit 26 also stores travel history information (first travel history information, second travel history information, second day, season, weather, travel time zone, air conditioner power consumption, travel power consumption, and average speed information). (Including travel history information).

  As information on the presence or absence of traffic jams, for example, the presence or absence of traffic jams can be detected in the travel date and time and the travel route included in the first travel history information, and the detected traffic jam information can be used. The day information includes, for example, the day of the week to which the traveling date and time included in the first traveling history information belongs. Furthermore, as the season information, for example, there is a season to which the date and time of travel included in the first travel history information belongs. Further, as the weather information, for example, the weather at the date and time of latitude and latitude and longitude included in the first travel history information can be detected, and the detected information can be used.

  Furthermore, as the time zone information, for example, the time zone to which the date and time of travel included in the first travel history information belongs can be mentioned. Examples of the information on the power consumption of the air conditioner include information on the air conditioner on / off included in the first travel history information and information on the power consumption per unit time of the air conditioner. The travel power consumption information includes, for example, a reduction amount per unit time of the remaining battery level during travel included in the first travel history information. Furthermore, examples of the average speed information include an average value in a set time (for example, 10 minutes) of the vehicle speed included in the first travel history information.

  In the present embodiment, the travel history recording unit 19 uses the information on the guide route output from the navigation device 18 as the travel route. However, other configurations may be employed. For example, when there is a portion in which the vehicle A actually travels on a different route in the travel route of the first travel history information, the travel history storage unit 26 stores the travel history stored in the travel history storage unit 26. Based on the information (latitude and longitude), the travel route on which the vehicle A actually traveled is corrected. Thereby, the travel history accumulating unit 26 accumulates information on the travel route on which the vehicle A actually traveled.

  As the information of the actually traveled route, a general latitude / longitude sequence after dead reckoning, or a road link sequence, and further a latitude / longitude sequence after map matching or a road link sequence can be adopted. Dead reckoning is, for example, position information obtained by correcting GPS latitude and longitude detected by the position detection unit 5 according to speed information from the vehicle speed detection unit 9. Furthermore, a method for improving the correction accuracy by adding information of a gyro sensor (acceleration sensor) (not shown) is also known and may be used. The map matching means the GPS latitude / longitude detected by the position detection unit 5 or the latitude / longitude after the dead reckoning, the road link and node information held by the navigation device 18, and the guidance route information if navigation is being performed. In addition, it is known as a method for detecting a plausible road location after determining whether or not the vehicle is traveling on a road and on which road the vehicle has passed.

  In particular, in the present embodiment, when the information on the travel route output from the in-vehicle device 1 is accumulated, the start point and the end point that are the end points of the travel route are extracted, and only the information on the end points is accumulated. Generate data for Even if the position of the two end points and the travel route between them are the same travel route, the battery power consumption is different when traveling from one end point to the other end point and traveling from the other end point to the other end point. This is because they may be different. For example, when the altitudes of the two end points are different, the uphill and the downhill are reversed, and the power consumption of the battery increases when there are more uphills. Even if the altitudes of the two end points are the same, the degree of traffic congestion may be different between the upstream lane and the downstream lane, and the greater the traffic congestion, the longer the travel time and the power consumption of the battery. For this reason, in this embodiment, the starting point and ending point of the travel route are distinguished and stored in the sub-database. The information of this sub-database (referred to as the endpoint sub-database) is used when determining the order of searching for the same / similar route, and will be described in detail later.

<Running history statistical processing>
FIG. 6A is a flowchart showing a subroutine of the travel history statistical process (step S40) of FIG. 2B. The travel history statistical processing is executed by the history statistical processing unit 27 of the vehicle information providing device 3, and when the history statistical processing unit 27 receives the presentation route search request (step S202 in FIG. 4) transmitted by the terminal device 2. The following history statistical processing is executed.

As shown in FIG. 6A, first, in step S401, historical statistics processor 27 obtains the start point P _O and destination point P _D from the received presentation route search request. Then, the history statistical processing unit 27, based on the map information by the map information storage section 25 has stored, retrieves the planned route to the destination P _D from the start point P _O acquired (acquired). The planned route may be a route that can be reached from the starting point P _O to the destination P _D, it is not particularly limited, for example, capable of traveling a departure point P _O and destination point P _D in the shortest time travel A route, a travel route that travels in the shortest distance, a travel route that uses a highway / toll road, a travel route that uses a general road, and the like are set as necessary.

  In the present embodiment, the history statistical processing unit 27 provided in the vehicle information providing apparatus 3 searches for (acquires) the planned route. However, other configurations may be employed. For example, the navigation device 18 provided in the in-vehicle device 1 may be configured to search for a planned route. In this case, if the navigation device 18 transmits the search result of the planned route to the history statistical processing unit 27 and the history statistical processing unit 27 receives (acquires) the planned route transmitted from the navigation device 18. Good.

  Subsequently, the process proceeds to step S402, and the history statistics processing unit 27 acquires information on the remaining battery level in accordance with the received presentation route search request. As a method for acquiring information on the remaining battery level, a method may be used in which the terminal device 2 makes an inquiry to the remaining battery level detection unit 11 of the vehicle A via the data center B, or the user inputs an arbitrary remaining battery level. It is good also as a method. According to the former method, the calculation based on the latest remaining battery level can be performed when actually departing, so that a result according to the current state can be obtained. In addition, according to the latter method, since the user can designate the remaining battery level in advance, for example, it is possible to obtain a result assuming that the battery starts after it is 100% charged.

Next, the process proceeds to step S403. In step S403, the history statistics processing unit 27 searches for a similar route. Specifically, the history statistical processing unit 27 sets a departure area R _O and a destination area R _D based on the departure point P _O and the destination point P _D included in the received presentation route search request. Here, FIG. 7 is a diagram for explaining the similar route search method of the present embodiment. As shown in FIG. 7 (A), in the present embodiment, the history statistical processing unit 27 sets the circular range with a radius r _O centered on the departure point P _O to the starting area R _O, and, setting the circular range with a radius r _D centered on the destination point P _D in the destination area R _D. Note that the method of setting the departure point and the destination point from the departure point and the destination point is not limited to a circular range having a certain radius, and may be a predetermined geometric shape such as a regular polygon.

Next, the history statistical processing unit 27 starts and ends within the set departure region _RO and destination region _RD from the first traveling history information (traveling route) accumulated by the traveling history accumulation unit 26. A travel route having a point is retrieved, and the retrieved travel route is extracted as a similar route. Specifically, the history statistical processing unit 27 sets, as a similar route, a travel route having a start point in the departure area R _O and an end point in the destination area R _D. For example, in the example shown in FIG. 7 (B), with respect to the planned route connecting the departure point P _O and destination point P _D, two "similar route 1" and an example that the detected "similar route 2" Show.

In the present embodiment, the radius r _O and the radius r _D that define the size (width) of the departure area R _O and the destination area R _D are set to a predetermined distance (for example, 5 km). Can do. According to the present embodiment, when searching for a similar route in this way, by setting a certain range such as a departure area R _O and a destination area R _D having a predetermined range, the travel history accumulation unit 26 accumulates It is possible to reduce the situation that there is no corresponding similar route in the first travel history information (travel route), and thus it is possible to appropriately set the similar route. Conversely, by limiting this range to a certain range, that is, by not setting an excessively wide range, the search load for similar routes can be reduced and the search time can be shortened.

  In step S403, the similar route that has been searched and hit in this way is set as a presentation route. The number of presentation routes is not particularly limited, and may be one or more. When similar routes are detected, all the detected similar routes may be set as the presentation routes, or one of all detected similar routes may be set according to a predetermined condition. Two or more similar routes may be selected and used as the presentation route. Examples of the predetermined condition include a method of selecting a similar route close to the current condition in consideration of conditions such as travel time (season, temperature), use of air conditioner during travel, and the like. Alternatively, a similar route may be selected in consideration of power consumption (for example, a route having the largest and smallest power consumption among the similar routes may be selected).

In step S403, the history statistical processing unit 27 determines that there is no similar route in the first travel history information (travel route) accumulated by the travel history accumulation unit 26, that is, the departure region R _O and If there is no travel route having a start point and an end point in the destination area _RD , the extraction of a similar route is abandoned. When the similar route is abandoned, the fact is temporarily stored by setting a corresponding flag.

In particular, in the present embodiment, the similar route search process in step S403 is executed according to the following procedure. FIG. 6B is a flowchart illustrating an example of a subroutine of step S403 in FIG. 6A. In the similar route search processing of this example, in order to reduce the search load (which can also be referred to as search cost such as search time) as much as possible, first, in step S701, the end point information of the travel history information stored in the end point sub-database is used. and extracts the data number N _O starting point present in the starting region R _O (similar starting point), and a data number N _D of termination points existing object area R _D (similar end point). In the end point sub-database, start point information and end point information consisting of longitude / latitude information are stored separately, so when the departure area is specified, the start point information existing within that range is immediately extracted and the destination area When is specified, end point information existing within the range is immediately extracted.

Next, at step S702, compares the data number N _O similar starting points existing extracted departing area R _O, the magnitude of the data number N _D similar termination points existing object area R _D, the number of data It is determined which of the regions R _O and _RD with the smaller number is. If the data number N _O of the similar start point is larger than the data number N _D of the similar end point, the processing of steps S703 to S706 is executed, otherwise, the data number N _O of the similar start point is the similar end point. If it is less data number _{N D} performs processing of step S707～S710. In step S702 shown in Figure 6B of the present example, when the data number N _D of similar end point to the data number N _O similar starting point is equal to the processing proceeds to step S707, the case where the number of data is equal in Since the search loads are also equal, the process may proceed to step S703.

If it is determined in step S702 that the data number N _O of the similar start point is larger than the data number N _D of the similar end point and the number of data is smaller in the destination area _RD , the travel history is determined in step S703. Of the travel routes stored in the database of the storage unit 26, a travel route whose end point exists in the destination area _RD is extracted and temporarily stored as a first travel route. Then, in step S704, it scans the temporarily stored first traveling route in order to determine whether or not the start point is present in the starting region R _O. As a result of the determination, the first travel route existing in the departure area is temporarily stored as the second travel route in step S705, while the first travel route not existing in the departure area is processed in step S705. If not, the process proceeds to step S706. In subsequent step S706, it is determined whether or not scanning of all the first travel routes has been completed. If not, the process returns to step S704, and step S704 is performed until scanning of all of the first travel routes is completed. The process of S706 is repeated. When scanning is completed for all the first travel routes, the process proceeds to step S711, and the temporarily stored second travel route is output as a travel route that is the same as or similar to the planned route, that is, a presentation route.

On the other hand, if it is determined in step S702 that the data number N _O of the similar start point is equal to or less than the data number N _D of the similar end point, and that the number of data is small is the departure area R _O , at S707, out of the travel routes accumulated in the database of the travel history accumulation unit 26 extracts the traveling route whose starting point is present in the starting region R _O, temporarily stores it as the first traveling route. In step S708, the temporarily stored first travel route is sequentially scanned, and it is determined whether or not the end point exists in the destination area _RD . As a result of this determination, the first travel route existing in the destination area is temporarily stored as the second travel route in step S709, while the first travel route not existing in the destination area is processed in step S709. If not, the process proceeds to step S710. In subsequent step S710, it is determined whether or not scanning of all the first travel routes has been completed. If not, the process returns to step S708, and step S708 is performed until scanning of all of the first travel routes is completed. The process of S710 is repeated. When scanning is completed for all the first travel routes, the process proceeds to step S711, and the temporarily stored second travel route is output as a travel route that is the same as or similar to the planned route, that is, a presentation route.

  As described above, in the similar route search process of the present embodiment, the number of data at the end points of the travel data stored in the travel history storage unit 26 is determined, and the corresponding travel data is first extracted for the end points with a small number of data. Since it is determined whether the other end point corresponds to the extracted travel data, a similar route can be extracted with a minimum search load.

FIG. 6C is a flowchart illustrating another example of the subroutine of step S403 in FIG. 6A. The presentation route search request received in step S401 in FIG. 6A, an example in which contains waypoints P _W in addition to the departure point P _O and the destination point P _D. For this waypoint P _W , as with the departure area R _O and the destination area _RD shown in FIG. 7A, the history statistical processing unit 27 has a circular shape with a radius r _W centered on the way point P _W. set in over the region R _W range. The method for setting the through region R _W from via-point P _W is not limited to a circular range of a predetermined radius, for example may be a predetermined geometric shapes such as a regular polygon. The via hits by setting a region R _W including waypoints P _W when searching for the traveling route through the via-point input can be set to an appropriate value.

In similar route search process of this example, first at step S801, using information of the end points of the travel history information stored in the endpoint sub-database described above, the start point present in the starting region R _O of (analogous starting point) The number of data N _O and the number of data N _D of end points (similar end points) existing in the destination area _RD are extracted. In the end point sub-database, start point information and end point information consisting of longitude / latitude information are stored separately, so when the departure area is specified, the start point information existing within that range is immediately extracted and the destination area When is specified, end point information existing within the range is immediately extracted.

Next, at step S802, the comparing and the data number N _O similar starting points existing extracted departing area R _O, the magnitude of the data number N _D similar termination points existing object area R _D, the number of data It is determined which of the regions R _O and _RD with the smaller number is. If the data number N _O of the similar start point is larger than the data number N _D of the similar end point, the processing of steps S803 to S808 is executed, otherwise, the data number N _O of the similar start point is the similar end point. If it is less data number _{N D} performs processing of step S809～S814. In step S802 shown in Figure 6C of the present example, when the data number N _D of similar end point to the data number N _O similar starting point is equal to the processing proceeds to step S809, if the number of data is equal in Since the search loads are also equal, the process may proceed to step S803.

If it is determined in step S802 that the data number N _O of the similar start point is larger than the data number N _D of the similar end point and the number of data is smaller in the destination area _RD , the travel history is determined in step S803. Of the travel routes stored in the database of the storage unit 26, a travel route whose end point exists in the destination area _RD is extracted and temporarily stored as a first travel route. In step S804, the temporarily stored first travel route is sequentially scanned to determine whether or not the starting point exists in the departure area R _O. As a result of this determination, the first travel route existing in the departure area is temporarily stored as the second travel route in step S805, and then in the subsequent step S806, the travel temporarily stored as the second travel route. route it is determined whether or not to pass through the through regional R _W. Since the information of the traveling route as previously described contains the latitude and longitude sequence and link series, first the information scans whether there in through the region R _W, contained in over the region R _W The two travel routes are temporarily stored as the third travel route in step S807.

  On the other hand, for the first travel route in which the starting point of the first travel route temporarily stored in step S804 does not exist in the departure area, the process proceeds to step S808 without performing the processing of steps S805 to S807. In step S808, it is determined whether or not all the first travel routes have been scanned. If not, the process returns to step S804, and steps S804 to S808 are performed until all the first travel routes have been scanned. Repeat the process. When scanning is completed for all the first travel routes, the process advances to step S815 to output the temporarily stored third travel route as a travel route that is the same as or similar to the planned route, that is, a presentation route.

On the other hand, if it is determined in step S802 that the data number N _O of the similar start point is equal to or less than the data number N _D of the similar end point and that the number of data is small is the departure region R _O , at S809, out of the travel routes accumulated in the database of the travel history accumulation unit 26 extracts the traveling route whose starting point is present in the starting region R _O, temporarily stores it as the first traveling route. In step S810, the temporarily stored first travel route is sequentially scanned, and it is determined whether the end point exists in the destination area _RD . As a result of the determination, the first travel route existing in the destination area is temporarily stored as the second travel route in step S811, and then the travel temporarily stored as the second travel route in step S812. route it is determined whether or not to pass through the through regional R _W. Since the information of the traveling route as previously described contains the latitude and longitude sequence and link series, first the information scans whether there in through the region R _W, contained in over the region R _W The two travel routes are temporarily stored as the third travel route in step S813.

  On the other hand, for the first travel route in which the end point of the first travel route temporarily stored in step S810 does not exist in the destination area, the process proceeds to step S814 without performing the processing of steps S811 to S813. In step S814, it is determined whether or not all the first travel routes have been scanned. If not, the process returns to step S810, and steps S810 to S814 are performed until all the first travel routes have been scanned. Repeat the process. When scanning is completed for all the first travel routes, the process advances to step S815 to output the temporarily stored third travel route as a travel route that is the same as or similar to the planned route, that is, a presentation route.

  In this way, in the similar route search process of the present embodiment shown in FIG. 6C, the number of data at the end points of the travel data stored in the travel history storage unit 26 is determined, and the corresponding travel is performed first for the end points with a small number of data. Since the data is extracted and it is determined whether the other end point corresponds to the extracted travel data, it is possible to extract the similar route with the minimum search load. In addition to this, when extracting a travel route that passes through a specific transit area, it is necessary to perform a search for a travel route that includes a large amount of information such as a latitude / longitude sequence or a road link sequence, so the search load However, in this example, a search for such a travel route is performed for a limited travel route with a narrowed start point and end point. A travel route similar to the planned route including the waypoint can be extracted.

FIG. 6D is a flowchart showing yet another example of the subroutine of step S403 in FIG. 6A. The presentation route search request received in step S401 in FIG. 6A, an example in which contains multiple waypoints P _W in addition to the departure point P _O and the destination point P _D. Even in the case where there are a plurality of waypoints _{PW, the} search is started from the start point or the end point with the smaller number of data similarly to the similar route search process shown in FIG. When the route that passes through the transit area is narrowed down next, the number of passing data is compared for each transit area, and from the transit area where the number of transit data is small Continue to refine. The process of steps S901 → S902 → S903 → S904 in FIG. 6D is the same as the process of steps S801 → S802 → S803 → S804 in FIG. 6C. Since the process is the same as the process of steps S801 → S802 → S809 → S810 in 6C, the description of the example illustrated in FIG. 6C is incorporated herein and the description of the present example is omitted.

  As a premise of this example, the travel history accumulation unit 26 of the vehicle information providing device 3 extracts points on the route of the travel route when accumulating the information of the travel route output from the in-vehicle device 1. A sub-database or table format data in which only the information of the upper point is accumulated is generated. As described above, since the travel route information includes position information such as a latitude / longitude number sequence and a road link sequence, the sub-database (routed region sub-database and To generate).

In step S904 or S906 in FIG. 6D, if the start point of the first travel route exists in the departure area or the end point exists in the destination area, the process proceeds to step S907, and the first travel route is set to the second route. Temporarily memorize as travel route. The stored second travel route is a travel route in which the start point is included in the departure area and the end point is included in the destination area. In step S907, the position information on the route existing in the plurality of route regions R _W1 and R _W2 is scanned using the route region sub-database described above, and the number of passing data (travel route) of the travel route associated therewith is scanned. ) N _W1 and N _W2 are extracted. In this example, it is assumed that two waypoints are set, but even if there are three or more waypoints, the same can be done.

Then, at step S908, as compared to passing data number N _W1 of the travel route that passes through the through region R _W1 extracted, the magnitude of the passing data number N _W2 of the travel route that passes through the through region R _W2, data It is determined which route area R _W1 or R _W2 is smaller in number. When passing the data number _{N W2} via local _{R W2} is larger than the pass data number _{N W1} via local _{R W1} executing the processing of step S909~S912 are otherwise, that number of passes data through the region _{R W2} If N _W2 is equal to or less than the passage number of data _{N W1} via local _{R W1} executes step S914～S917. In step S908 shown in FIG. 6D of the present embodiment, although the case passes data number _{N W1} of passing data number _{N W2} and via local _{R W1} via local _{R W2} are equal to the processing proceeds to step S914, passing the number of data If the number is the same, the search load is also equal, and the process may advance to step S909.

Many of the pass data number _{N W1} of passing data number _{N W2} is via local _{R W1} via local _{R W2} at step S908, if the small number of passes data is determined to be over the region _{R W1} is first In step S909, after the travel route passing through the transit area _RW1 is extracted from the second travel route, the travel route passing through the transit area _RW2 is further extracted from the narrowed travel routes (step S910). . In subsequent step S911, the travel route thus narrowed down is temporarily stored as a third travel route.

On the other hand, in step S910, for the second traveling route that does not pass through the through region _{R W2} albeit at driving route passes through the through region _{R W1} proceeds to step S912 without performing the processing in step S911. In step S912, it is determined whether or not all the first travel routes have been scanned. If not, the process returns to step S904, and steps S904 and S907 are performed until all the first travel routes have been scanned. The process of S912 is repeated. When scanning is completed for all the first travel routes, the process proceeds to step S913, and the temporarily stored third travel route is output as a travel route that is the same as or similar to the planned route, that is, a presentation route.

Determining contrast, in step S908, through no more than pass the data number _{N W1} of passing data number _{N W2} is via local _{R W1} region _{R W2,} as a small number of passes data is via local _{R W2} in a case where it is initially After extracting the travel route passing through the region R _W2 of the second traveling route at step S914, the travel route passing through the region R _W1 of the narrowed travel route Further extraction is performed (step S915). In the subsequent step S916, the travel route thus narrowed down is temporarily stored as the third travel route.

On the other hand, in step S915, for the second traveling route that does not pass through the through region _{R W1} albeit at driving route passes through the through region _{R W2} proceeds to step S917 without performing the processing in step S916. In step S917, it is determined whether or not scanning of all first travel routes has been completed. If not, the process returns to step S906, and steps S906 to S912 are performed until scanning of all first travel routes is completed. Repeat the process. When scanning is completed for all the first travel routes, the process proceeds to step S913, and the temporarily stored third travel route is output as a travel route that is the same as or similar to the planned route, that is, a presentation route.

  As described above, in the similar route search process of the present embodiment shown in FIG. 6D, the number of data of the end points of the travel data stored in the travel history storage unit 26 is determined, and the travel corresponding to the end points with the smaller number of data first is determined. Since the data is extracted and it is determined whether the other end point corresponds to the extracted travel data, it is possible to extract the similar route with the minimum search load. In addition to this, when extracting a travel route that passes through a specific transit area, it is necessary to perform a search for a travel route that includes a large amount of information such as a latitude / longitude sequence or a road link sequence, so the search load In this example, in addition to performing a search for such a travel route on a limited travel route with a narrowed start point and end point, a plurality of travel routes are searched. When the waypoints are set, narrowing down is started from the waypoints where the number of passing data is small, so that it is possible to extract a travel route similar to a planned route including a plurality of waypoints with a minimum search load.

  Returning to FIG. 6A, in subsequent step S404, the history statistical processing unit 27 refers to the combined route generated by combining the plurality of travel routes stored in the travel history storage unit 26, and A similar synthetic route that is the same or similar synthetic route is searched and determined.

Here, FIG. 8 is an explanatory diagram showing the composite route, in which three travel routes traveled by the vehicle A1 are shown by dotted lines, three travel routes traveled by the vehicle A2 are shown by dashed lines, and the vehicle A3 travels Four traveling routes are indicated by fine dotted lines, and three combined routes 1, 2, and 3 obtained by combining them are shown. As shown in FIG. 8, the history statistical processing unit 27 extracts information on the combined routes 1, 2, 3,... Obtained by combining a plurality of travel routes traveled by the same vehicle, and is set in step S403 described above. A synthesized route having a start point in the departure area R _O and an end point in the destination area R _D is extracted as a similar synthesized route. Such a synthetic route is extracted when the history statistical processing unit 27 searches for a similar synthetic route as shown in the subroutine of FIG. You may accumulate | store similarly to a driving | running route.

Incidentally, when a combined route is generated and stored in advance by the travel history storage unit 26, it can be generated by the following method. FIG. 9 is a diagram for explaining an example of a synthetic route generation method. The synthetic route generation method will be described with reference to the example shown in FIG. That is, first, the travel history accumulation unit 26 refers to the first travel history information stored from among the travel route that a particular vehicle A ₁ traveled to extract any travel route. For example, in the example shown in FIG. 9 (A), it has an arbitrary traveling route as "traveling route 1 of the vehicle A _1". Then, the travel history accumulating unit 26 sets a circular range having a radius r _S from the end point of the extracted “travel route ₁ of the vehicle A ₁ ” as the composite point range R _S , and travel in which the vehicle A ₁ travels. A search is made for a travel route having a start point within the composite point range R _S from the routes. As a result, when the travel route having a starting point in the synthesis point range R _S is retrieved, the travel history accumulation unit 26 performs synthesis of these travel route, thereby generating a synthetic route to produce Accumulate synthetic routes. That is, in the example shown in FIG. 9 (A), combines the a "vehicle A traveling route 1 of _1" synthetic point range R has a starting point in the _S "traveling route 2 of the vehicle A _1", which It generates a synthesis route consisting of the "traveling route 2 of the vehicle a _1", "traveling route 1 of the vehicle a _1" by, and accumulates it. The radius r _S is not particularly limited, but can be about 1 to 5 km, for example.

In this case, the start point and end point of the synthesis route are the end points (points excluding the points used for the synthesis) of the synthesis route. That is, in the synthesis route consisting shown in FIG. 9 (A) and "traveling route 1 of the vehicle A _1" and "traveling route 2 of the vehicle A _1", the starting point of the "traveling route 1 of the vehicle A _1" is synthesized It becomes the start point of the route, and the end point of “travel route 2 of vehicle A ₁ ” becomes the end point of the combined route.

In the example shown in FIG. 9A, the case where two traveling routes are combined is illustrated, but the number of combined driving routes is not limited to two when obtaining a combined route, but is set to three or more. Also good. That is, for example, as in the example shown in FIG. 9 (B), the synthesis route consisting of "vehicle traveling route 1 A _1" and "traveling route 2 of the vehicle A _1", "vehicle A ₁ of the travel route 2 from the end point of "having a starting point the range of the circular in the synthesis point range R _S having a with a radius r _S" vehicle traveling route 3 of a ₁ "and further elaborated to," traveling route 1 of the vehicle a ₁ " and it is possible to produce a synthesis route consisting of "vehicle a ₁ of the travel route 2" and "traveling route 3 of the vehicle a _1". In the combined route obtained in this way, the starting point of “the traveling route ₁ of the vehicle A ₁ ” is the starting point of the combined route, and the end point of the “traveling route 3 of the vehicle A ₁ ” is This is the end point of the synthesis route.

Also, as in the example shown in FIG. 10 (A), the travel route having a starting point a circular range with a with a radius r _S from the end point of the "traveling route 1 of the vehicle A _1" Synthesis point range R _S but "vehicle a ₁ of the travel route 2" and when there are two, such as "travel route 4 of the vehicle a _1" is running route 2 of the "vehicle a _1" traveling route 1 of the vehicle a ₁ " in addition to the synthetic route consisting a ", it is also possible to produce a synthesis route consisting of a" vehicle a ₁ of the travel route 1 "and" traveling route 4 of the vehicle a ₁ ". That is, in this case, of three traveling route of the vehicle A _1, can generate two synthetic routes. In the example shown in FIG. 10A, a circular route having a radius r _S from the end point of “vehicle A ₁ travel route 1” is a travel route having a start point within the composite point range R _S. Although the example in which two exist is shown, the same can be applied to the case in which three or more exist. Here, FIG. 10 is a diagram for explaining an example of a synthetic route generation method.

Furthermore, as in the example shown in FIG. 10 (B), consisting of a case where four running route is present, for example, the "traveling route 1 of the vehicle A _1" and "traveling route 2 of the vehicle A _1" synthesis route, consisting of a "vehicle a ₁ of the travel route 1" and the synthesis route consisting of the "traveling route 4 of the vehicle a _1", "vehicle a ₁ of the travel route 5" and "traveling route 2 of the vehicle a _1" synthesis route, and it may also generate four synthetic routes of the synthesis route consisting of a "vehicle a ₁ of the travel route 5" and "traveling route 4 of the vehicle a _1".

In the above, an example in which a combined route is generated for a specific vehicle A ₁ has been illustrated. However, as illustrated in FIG. 8, the travel history accumulation unit 26 includes vehicles A ₂ and vehicles A ₃ other than the vehicle A _1. ,..., A composite route is generated for each vehicle by combining a plurality of travel routes traveled by each vehicle, and the travel history storage unit 26 records the composite route generated in this way. Thus, a plurality of synthesis routes synthesized for each vehicle are accumulated.

Further, in the above example, sets the circular range with a with a radius r _S from the end point of any of the travel route as a combined point range R _S, in the synthetic point range R _S, synthesized travel route having a starting point For example, as shown in FIG. 11A, a rectangular range formed by latitude ± d1 and longitude ± d2 is set as the center as the synthesis point range _RS . May be. That is, for example, when the latitude and longitude of the end point are (latitude, longitude) = (x, y), (x-d1, y-d2), (x + d1, y-d2), (x-d1, A rectangular area surrounded by (y + d2) and (x + d1, y + d2) may be set as the synthesis point range R _S. For example, d1 and d2 can be the same as the radius r _S described above.

Alternatively, as shown in FIG. 11B, a mesh obtained by dividing latitude and longitude on a map at predetermined intervals (the area is divided into meshes of approximately the same size based on latitude and longitude). An area of 9 mesh centering on the mesh where the end point of an arbitrary travel route is located may be set as the synthesis point range R _S. That is, in the example shown in FIG. 11B, the end points are indexed into the range of the mesh to which the end points belong and the eight meshes adjacent to the mesh, and this is set as the composite point range R _S. In addition, as a method of dividing the mesh, for example, a method of arbitrarily setting latitude and longitude in units of 0.1 degrees may be adopted, and generally used map mesh code, piano code, geohash, geohex, etc. You may adopt the method according to. By adopting such a method, it is possible to more easily set the synthesis point range R _S , thereby reducing the calculation load when generating the synthesis route.

Further, as the composite point range _RS , a range on the road network starting from the end point may be set to a predetermined equidistant distance (for example, 5 km), or within a predetermined distance range from the end point. And a range within a predetermined altitude range may be set for the altitude at the end point.

Then, in step S404, historical statistics processing unit 27 of this way is synthesized by the travel history accumulation unit 26 accumulates synthetic route, the starting point in the starting area R _O set in step S403 described above A synthetic route that is present and has an end point in the destination area _RD is extracted as a similar synthetic route, and the extracted similar synthetic route is determined as a presentation route. If such a similar synthesis route (a synthesis route having a start point in the departure area R _O and an end point in the destination area R _D ) is detected, all the similar synthesis routes detected are detected. May be set as a presentation route, or one or two or more similar synthesis routes may be selected from all detected similar synthesis routes according to a predetermined condition and used as the presentation route. . Examples of the predetermined condition include a method of selecting a similar composite route that is close to the current condition in consideration of conditions such as travel time (season, temperature), use of air conditioner during travel, and the like. Alternatively, the similar combined route may be selected in consideration of the power consumption (for example, the highest and lowest power consumption among similar routes may be selected).

In step S404, the history statistical processing unit 27 includes a combined route having a start point and an end point in the departure area R _O and the destination area _RD among the combined routes stored in the history storage unit 26. If not, abandon the extraction of similar synthesis routes.

  In particular, in the present embodiment, the similar synthetic route search process in step S404 of FIG. 6A is executed in the following procedure. FIG. 6E is a flowchart illustrating an example of a subroutine of step S404 in FIG. 6A. In the case of this example as well, similar to the similar route search processing shown in FIGS. 6B to 6D, the search is started from the start point or the end point with the smaller number of data, and the other one of the extracted travel routes is extracted from this. A route that extracts the ones whose end points exist in the departure area or destination area, but even if the other end point does not exist in the departure area or destination area, a combination of multiple driving data without giving up the search Extract as The process of steps S1001 → S1002 → S1003 → S1004 in FIG. 6E is the same as the process of steps S701 → S702 → S703 → S704 in FIG. 6B. Since this is the same as the process of steps S701 → S702 → S707 → S708 in 6B, the description of the example shown in FIG. 6B is incorporated here and the description of this example is omitted.

In step S1004 in FIG. 6E, the results starting point of the first travel route is determined whether present in the starting region R _O, as in the example case shown in FIG. 6B present, third proceeds to step S1009 In this case, the third route is output as a presentation route that is the same as or similar to the planned route in step S1019.

On the other hand, if the starting point of the first travel route does not exist in the departure area R _O , the process is terminated as no corresponding travel route in the example shown in FIG. 6B, but the process proceeds to step S1005 in this example. The start point is set as the virtual waypoint _PW , and the search is continued. In the following step S1006, the history statistical processing unit 27 sets a virtual via regional _{R W} based on the first virtual waypoints _{P W.} This virtual transit area is a circular range having a radius r _W centered on the virtual transit point P _W in the same manner as the above-described departure area, destination area, and transit area. For example, a predetermined geometric shape such as a regular polygon may be used. Then historical statistics processor 27, in a travel route stored in the history information storage unit 26, extracts the traveling route whose end point is present on the virtual through area R _W, which is the extracted at step S1007 travel The route is temporarily stored as the second travel route.

Then, in step S1008, the starting point of the temporarily stored traveling route as the second traveling route is to extract those present in the starting region R _O, the second travel route which is the extracted at step S1009 Temporarily store as the third travel route. In subsequent step S1010, it is determined whether or not scanning of all the first travel routes has been completed. If not, the process returns to step S1004, and step S1004 is performed until scanning of all of the first travel routes is completed. The process of ~ S1010 is repeated. When scanning is completed for all the first travel routes, the process proceeds to step S1019, and the temporarily stored travel route obtained by combining the first travel route, the second travel route, and the third travel route is the same as or similar to the planned route. To be output as a travel route, that is, a presentation route.

Note that, in step S1006, in a travel route stored in the history information storage unit 26, when the traveling route whose end point is present on the virtual over the region _{R W} does not hit, performing the processing of step S1007~S1009 Instead, the process proceeds to step S1010. Further, in step S1008, even if those whose starting point of the temporarily stored traveling route as the second traveling route is present in the starting region R _O is not hit, to step S1010 without executing step S1009 move on.

As a result of determining whether or not the end point of the first travel route exists in the destination area _RD in step S1012 of FIG. 6E, if it exists, the process proceeds to step S1017 as in the example shown in FIG. In this case, the third route is output as a presentation route that is the same as or similar to the planned route in step S1019.

On the other hand, if the end point of the first travel route does not exist in the destination area _RD , the process is terminated in the example shown in FIG. 6B assuming that there is no corresponding travel route, but in this example, the process proceeds to step S1013. The end point is set as a virtual waypoint _PW , and the search is continued. In the following step S1014, the history statistical processing unit 27 sets a virtual via regional _{R W} based on the first virtual waypoints _{P W.} This virtual transit area is a circular range having a radius r _W centered on the virtual transit point P _W in the same manner as the above-described departure area, destination area, and transit area. For example, a predetermined geometric shape such as a regular polygon may be used. Then historical statistics processor 27, in a travel route stored in the history information storage unit 26, extracts the traveling route whose starting point is present in the virtual through area R _W, which is the extracted at step S1015 travel The route is temporarily stored as the second travel route.

Then, in step S1016, out of the travel routes temporarily stored as the second travel route, those whose end points exist in the destination area _RD are extracted, and in step S1017, the extracted second travel route is extracted. Temporarily store as the third travel route. In subsequent step S1018, it is determined whether or not scanning of all the first travel routes has been completed. If not, the process returns to step S1012, and step S1012 is performed until scanning of all of the first travel routes is completed. Repeat the process of ~ S1018. When scanning is completed for all the first travel routes, the process advances to step S1019 to output the temporarily stored third travel route as a travel route that is the same as or similar to the planned route, that is, a presentation route.

Note that, in step S1014, in a travel route stored in the history information storage unit 26, when the traveling route whose starting point is present in the virtual over the region _{R W} does not hit, performing the processing of step S1015~S1017 Instead, the process proceeds to step S1018. Also, in step S1016, even if the travel route temporarily stored as the second travel route whose end point exists in the destination area _RD does not hit, the process proceeds to step S1018 without performing the process of step S1017. move on.

It was set only one point virtual waypoints P _W in the example shown in FIG. 6E, when the starting point of the second traveling route in step S1008 does not hit those present in the starting region R _O, the respective starting point the The search may be continued until the starting point exists in the departure area by setting the second virtual waypoint _PW2 and performing the following inductive process. That is, when this inductive process is generalized, in steps S1004 to S1010, after extracting a travel route whose end point exists in the destination area _RD as the first travel route, the start point of the extracted first travel route the travel route end point existing in a virtual way area R _W is extracted as a second travel route containing respectively, ends the sequential starting point of the N traveling route extracted by repeating this virtual through area R _W containing respectively point present and the start point to extract the travel route existing in the starting region R _O as the (N + 1) driving route. Further, in step S1012～S1018, the travel route start point is present in the starting region R _O then was extracted as a first travel route, the end point of the first traveling route is the extracted virtual through area R _W containing respectively starting point traveling route starting point exists second extracted as a travel route, (the N 1 or more integer) the N traveling route extracted by sequentially repeating this virtual through area R _W including the end point, respectively And a travel route having an end point in the destination area _RD is extracted as the (N + 1) th travel route. Then, when the terminal point is finally reached, a combined route obtained by combining the traveling routes, that is, a combined route from the first traveling route to the (N + 1) th traveling route is output as a similar combined route. Note that when a route point is received from the terminal device 2 in addition to the departure point and the destination point, the virtual route point may be replaced with the route point actually input, and the above inductive search process may be executed.

  As described above, in the similar synthetic route search process of the present embodiment shown in FIG. 6E, the number of data at the end points of the travel data stored in the travel history storage unit 26 is determined, and the end point corresponding to the end point with the smaller number of data is applicable first. Since the travel data is extracted and it is determined whether or not the other end point corresponds to the extracted travel data, a similar route can be extracted with a minimum search load. In addition to this, even if a single driving route does not hit, a plurality of driving routes are recursively narrowed so that the search load is reduced, so a driving route that is the same as or similar to the planned route is presented as a composite route. can do.

  Returning to step S405 in FIG. 6A, the history statistical processing unit 27 determines whether or not the presentation route (similar route or similar combined route) has been determined in steps S403 and S404 described above. When the history statistics processing unit 27 determines that the presentation route (similar route or similar synthesis route) has been determined (step S405 = Yes), the history statistics processing unit 27 proceeds to step S406. On the other hand, if the history statistics processing unit 27 determines that the presentation route (similar route or similar synthesis route) could not be determined (step S405 = No), the history statistics processing unit 27 proceeds to step S408.

  If it is determined in step S405 that the presented route (similar route or similar combined route) has been determined, the process proceeds to step S406. In step S406, the history statistics processing unit 27 stores the travel history storage unit 26. From the second travel history information (charging via point), the charging via point that has passed through when traveling on the presentation route (similar route or similar combined route) determined in steps S403 and S404 described above is extracted.

  For example, when a presentation route that is a similar route is determined in step S403 described above, the history statistical processing unit 27 selects from the first travel history information stored in the travel history storage unit 26. The first traveling history information including the similar route is searched. Subsequently, the history statistical processing unit 27 selects the second travel history associated with the searched first travel history information from the second travel history information (the charging point) stored in the travel history storage unit 26. Extract charging points from information.

  In addition, in the above-described step S404, when a presentation route that is a similar combined route is determined, the history statistical processing unit 27 selects the first travel history information stored in the travel history storage unit 26 from the first travel history information. A plurality of first travel history information including each travel route forming a similar composite route is searched. Subsequently, the history statistical processing unit 27 is associated with the searched first travel history information among the second travel history information (information about the charging via point) stored in the travel history storage unit 26. Information on the waypoint through charging is extracted from each piece of travel history information. Then, the history statistics processing unit 27 sets each extracted charging point as a charging point that is light oil when traveling on the presentation route (similar route or similar synthetic route) determined in steps S403 and S404 described above.

  Subsequently, the process proceeds to step S407, where the history statistical processing unit 27 determines the presentation route determined in steps S403 and S404 described above from the first travel history information (power consumption information) accumulated in the travel history accumulation unit 26. The power consumption consumed when traveling on (similar route or similar combined route) is extracted. For example, when the presented route that is a similar route is determined in step S403 described above, the history statistical processing unit 27 extracts the power consumption from the first traveling history information including the similar route. In addition, in the above-described step S404, when a presentation route that is a similar combined route is determined, power consumption information is extracted from each of a plurality of first traveling history information including each traveling route that forms the similar combined route. To do. Subsequently, the history statistics processing unit 27 uses the total power consumption extracted as power consumption consumed when traveling on the similar combined route.

  If it is determined in step S405 that the presented route (similar route or similar combined route) could not be determined, the process proceeds to step S408. In step S408, the history statistical processing unit 27 is based on the theoretical performance of the host vehicle A. Thus, power consumption (hereinafter also referred to as theoretical power consumption) consumed when traveling on the planned route searched in step S401 described above is calculated. Specifically, the history statistics processing unit 27 sets the theoretical power consumption as the multiplication result of the total length of the planned route and the power consumption per unit distance determined in advance, and proceeds to step S409.

  Subsequently, the process proceeds to step S409, where the history statistical processing unit 27 extracts the position of the charging facility C existing in the vicinity of the planned route searched in step S401 described above based on the map information stored in the map information storage unit 25. Then, the process proceeds to step S410. Examples of the charging facility C in the vicinity of the planned route include the charging facility C existing along the planned route and the charging facility C within a set distance (for example, 20 m) from the planned route.

  Next, in step S410, the history statistical processing unit 27 performs a charging via point extraction process (see FIG. 12) based on the remaining battery level acquired in step S402 described above. In the charging via point extraction process, the history statistical processing unit 27 extracts the charging via point to be transmitted (provided) to the transmission source terminal device 2 from the charging via points acquired in step S406 or S409 described above. An example of the transmission source terminal device 2 is the terminal device 2 that is the transmission source of the presentation route search request that triggered the start of the history statistical processing. Further, in the charging via point extraction process, the possibility that the vehicle A cannot reach the destination point is determined, and when it is determined that there is a possibility that the destination point cannot be reached, an unreachable warning is given to warn to that effect. decide.

  FIG. 12 is a flowchart showing a sub-routine of the charging via point extraction process in step S410 of FIG. 6A. As shown in FIG. 12, first, in step S501, the history statistical processing unit 27 uses the remaining battery power acquired in step S402 described above as the power consumption extracted in step S407 or S408 described above (hereinafter also referred to as extracted power consumption). ) It is determined whether it is larger. When the history statistical processing unit 27 determines that the remaining battery capacity is greater than the extracted power consumption (step S501 = Yes), the history statistics processing unit 27 proceeds to step S502. On the other hand, when the history statistical processing unit 27 determines that the remaining battery level is equal to or less than the extracted power consumption (step S501 = No), the history statistical processing unit 27 proceeds to step S505.

  If it is determined in step S501 that the remaining battery level is greater than the extracted power consumption, the process proceeds to step S502. In step S502, the history statistical processing unit 27 stores the second travel history stored in the travel history storage unit 26. With reference to the information (charging point), it is determined whether or not there is an actual charging point among the charging points acquired in step S406 or S409 described above. The actual charging point includes the position of the charging facility C where at least one of the plurality of vehicles A has actually charged. When the history statistics processing unit 27 determines that there is a track record charging point (step S502 = Yes), the history statistics processing unit 27 proceeds to step S503.

  If the history statistical processing unit 27 determines that there is no actual charging point (step S502 = No), the history point processing unit 27 ends the charging point extraction process without extracting the charging point. Thereby, the history statistical processing unit 27 has a sufficient remaining battery capacity of the traveling battery 14 and when there is no actual charging via point among the charging via points acquired in step S406 or S409 described above. The information on the actual charging via point is not transmitted (provided) to the transmission source terminal device 2. Since the actual charging point may be a dedicated charging facility for a specific individual or corporation, it is desirable to preferentially extract a facility that is surely a public charging facility by statistical processing. For example, it has a configuration with a separate public charging facility database, and a method of extracting the data at the same location as this data, or a plurality of vehicles (for example, 5 or more) with different names (including corporations and individuals) are the same A method of extracting charging facilities that have a track record of charging at a point can be considered. In addition, when using these data, it is desirable to select the charging facility that is actually available in the expected arrival time zone of the route by giving priority to the available time zone. .

  On the other hand, if it is determined that there is an actual charging via point, the process proceeds to step S503, and in step S503, the history statistical processing unit 27 stores the second traveling history information (the charging via point) accumulated in the traveling history accumulation unit 26. ), The actual charging point is extracted from the charging points acquired in step S406 or S409 described above, and then the charging point extraction process is terminated. Thereby, the history statistical processing unit 27 has a sufficient remaining battery capacity of the traveling battery 14 and when there is an actual charging via point among the charging via points acquired in step S406 or S409 described above. Only the information on the actual charging via point is transmitted (provided) to the transmission source terminal device 2.

  If it is determined in step S501 described above that the remaining battery level is equal to or less than the extracted power consumption, the process proceeds to step S504. In step S504, the history statistical processing unit 27 is stored in the map information storage unit 25. Based on the map information, it is determined whether or not the charging facility C exists in the vicinity of the presentation route (similar route, similar combined route) determined in step S403 or S404 described above. Examples of the charging facility C that exists in the vicinity of the presentation route include the charging facility C that exists along the presentation route and the charging facility C that is within a set distance (for example, 20 m) from the presentation route. When the history statistics processing unit 27 determines that the charging facility C exists in the vicinity of the presentation route (step S504 = Yes), the history statistics processing unit 27 proceeds to step S505. On the other hand, if the history statistical processing unit 27 determines that there is no charging facility C in the vicinity of the presented route (step S504 = No), the history statistical processing unit 27 proceeds to step S506.

  If the presentation route cannot be determined in step S403 or S404 described above, the history statistical processing unit 27 plans based on the map information stored in the map information storage unit 25 and searched in step S401 described above. It is determined whether or not the charging facility C exists in the vicinity of the route. If the history statistical processing unit 27 determines that the charging facility C exists in the vicinity of the planned route (step S504 = Yes), the history statistical processing unit 27 proceeds to step S505. On the other hand, if the history statistics processing unit 27 determines that there is no charging facility C in the vicinity of the planned route (step S504 = No), the history statistics processing unit 27 proceeds to step S506.

  If it is determined in step S504 that the charging facility C exists in the vicinity of the presented route, the process proceeds to step S505. In step S505, the history statistical processing unit 27 stores the map information stored in the map information storage unit 25. Based on this, the position of the charging facility C existing in the vicinity of the presented route (similar route, similar combined route) (hereinafter also referred to as a recommended nearby charging via point) is extracted, and then the charging via point extraction process is terminated. Further, when the presented route (similar route, similar combined route) cannot be determined in steps S403 and S404 described above, the history statistical processing unit 27 is based on the map information stored in the map information storage unit 25. The recommended nearby charging via points that exist in the vicinity of the planned route are extracted. Thereby, the history statistical processing unit 27, when the remaining battery level of the traveling battery 14 is insufficient and there is a recommended nearby charging via point, only the information of the recommended neighboring charging via point is transmitted from the transmission source terminal. Transmit (provide) to the device 2.

  On the other hand, if it is determined in step S504 that the charging facility C does not exist in the vicinity of the presentation route, the process proceeds to step S506. In step S506, the history statistical processing unit 27 determines to perform an unreachable warning. The charging via point extraction process is terminated. Thereby, the history statistical processing unit 27, when the remaining battery capacity of the traveling battery 14 is insufficient and there is no recommended nearby charging via point, information on the recommended neighboring charging via point (charging via point). Is not transmitted (provided) to the transmission source terminal device 2.

  Returning to FIG. 6A, when the charging route extraction process ends, the process proceeds to step S411, and the history statistical processing unit 27 executes the power consumption correction process (see FIG. 13) based on the power consumption tendency of the driver of the vehicle A. In the power consumption correction process, the history statistics processing unit 27 includes the first driving history information stored in the traveling history storage unit 26 and the first driver ID specified by the driver ID included in the presentation route search request. With reference to the travel history information, power consumption consumed when traveling on the presented route (similar route, similar combined route) is calculated. Subsequently, the history statistical processing unit 27 corrects the power consumption extracted in step S406 or S409 described above based on the calculated power consumption.

  FIG. 13 is a flowchart showing a subroutine of power consumption correction processing in step S411 of FIG. 6A. As shown in FIG. 13, first, in step S601, the history statistics processing unit 27 acquires a driver ID (information for specifying a driver) from the received presentation route search request. Subsequently, the history statistics processing unit 27 includes first traveling history information (including the same driver ID as the acquired driver ID) in the first traveling history information accumulated by the traveling history accumulating unit 26 ( Hereinafter, it is determined whether there is transmission source travel history information). If the history statistics processing unit 27 determines that there is transmission source travel history information (step S601 = Yes), the history statistics processing unit 27 proceeds to step S603. On the other hand, if the history statistics processing unit 27 determines that there is no transmission source travel history information (step S601 = No), the history statistics processing unit 27 proceeds to step S602.

  If it is determined in step S601 that there is transmission source travel history information, the process proceeds to step S602. In step S602, the history statistical processing unit 27 directly corrects the power consumption calculated in step S407 or S408 described above. The power consumption is corrected (hereinafter also referred to as “corrected power consumption”), and the power consumption correction process is terminated. Thereby, the history statistical processing unit 27, when there is no transmission source travel history information in the first travel history information stored in the travel history storage unit 26, the consumption calculated in the above-described step S407 or S408. The power information is transmitted (provided) to the transmission source terminal device 2 as it is.

  On the other hand, if it is determined in step S601 that there is no transmission source travel history information, the process proceeds to step S603. In step S603, the history statistical processing unit 27 stores the transmission source travel history stored in the travel history storage unit 26. It is determined whether or not the information (travel route) includes the same travel route (hereinafter also referred to as the same travel route) as the similar route extracted in step S403 described above. When the history statistical processing unit 27 determines that there is the same travel route (step S603 = Yes), the history statistical processing unit 27 proceeds to step S604. On the other hand, when the history statistical processing unit 27 determines that there is no identical travel route (step S603 = No), the history statistical processing unit 27 proceeds to step S606. Note that the same travel route may be any route that can be determined to be the same as the similar route extracted in step S403 described above, and there may be a different portion as long as the amount can be determined as an error range.

  If it is determined in step S603 that there is the same travel route, the process proceeds to step S604. In step S604, the history statistical processing unit 27 selects the transmission source travel history information stored in the travel history storage unit 26. The power consumption consumed when traveling on the same travel route is extracted. Subsequently, the history statistical processing unit 27 sets the extracted power consumption as correction power consumption.

  In step S605, the history statistical processing unit 27 corrects the power consumption calculated in step S407 or S408 described above based on the power consumption for correction calculated in step S604 described above. As a power consumption correction method, for example, a method of replacing power consumption with power consumption for correction, a method of calculating an average value of power consumption and power consumption for correction, and a difference between power consumption b and power consumption for correction a There is a method of expressing a ± c using c. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and then ends the power consumption correction process. As a result, the history statistical processing unit 27 consumes power consumed when traveling on the same travel route when the same travel route exists in the transmission source travel history information stored in the travel history storage unit 26. And the corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, when it is determined in step S603 described above that there is no same travel route, the process proceeds to step S606, and in step S606, the history statistical processing unit 27 stores the transmission source travel history stored in the travel history storage unit 26. It is determined whether or not there is a similar type travel route in the information (travel route). As the similar type travel route, for example, there is a travel route having the same or similar road type as the presented route (similar route, similar composite route) determined in step S403 or S404 described above. If the presented route (similar route, similar combined route) cannot be determined in steps S403 and 404 described above, the planned route searched in step S401 described above is set as a similar type travel route. When the history statistics processing unit 27 determines that there is a similar type travel route (step S606 = Yes), the history statistics processing unit 27 proceeds to step S607. On the other hand, when the history statistics processing unit 27 determines that there is no similar type travel route (step S606 = No), the history statistics processing unit 27 proceeds to step S610.

  If it is determined in step S606 that there is a similar type travel route, the process proceeds to step S607. In step S607, the history statistical processing unit 27 refers to the transmission source travel history information stored in the travel history storage unit 26. Then, the power consumption per unit distance of the similar type travel route (hereinafter also referred to as the similar type power consumption rate) is calculated.

  In step S608, the history statistical processing unit 27 multiplies the similar type power consumption rate calculated in step S607 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S609, the history statistical processing unit 27 corrects the power consumption calculated in step S407 or S408 described above based on the power consumption for correction calculated in step S608 described above. The power consumption correction method can be the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. Thereby, the history statistical processing unit 27 corrects the power consumption with the similar type power consumption rate when there is a similar type travel route in the transmission source travel history information accumulated in the travel history accumulation unit 26. Then, the corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, if it is determined in step S606 described above that there is no similar type travel route, the process proceeds to step S610. In step S610, the history statistical processing unit 27 stores the transmission source travel stored in the travel history storage unit 26. It is determined whether or not there is a similar distance travel route in the history information (travel route). As the similar distance travel route, for example, there is a travel route having the same or similar overall length as the presentation route (similar route, similar composite route) determined in step S403 or S404 described above. If the presented route (similar route, similar combined route) cannot be determined in steps S403 and 404 described above, the planned route searched in step S401 described above is set as the similar distance travel route. For example, the history statistical processing unit 27 has a difference from the total length of the presented route in the transmission source travel history information (travel route) stored in the travel history storage unit 26 that is less than a set value (for example, ± 100 m). It is determined whether there is a travel route. When the history statistics processing unit 27 determines that there is a similar distance travel route (step S610 = Yes), the history statistics processing unit 27 proceeds to step S611. On the other hand, when the history statistics processing unit 27 determines that there is no similar distance travel route (step S610 = No), the history statistics processing unit 27 proceeds to step S614.

  If it is determined in step S610 that there is a similar distance travel route, the process proceeds to step S611. In step S611, the history statistical processing unit 27 refers to the transmission source travel history information stored in the travel history storage unit 26. Then, power consumption per unit distance of the similar distance travel route (hereinafter also referred to as similar distance power consumption rate) is calculated.

  In step S612, the history statistical processing unit 27 multiplies the similar distance power consumption rate calculated in step S611 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S613, the history statistical processing unit 27 corrects the power consumption calculated in step S407 or S408 described above based on the power consumption for correction calculated in step S612 described above. The power consumption correction method is the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. Thus, the history statistical processing unit 27 corrects the power consumption with the similar distance power consumption rate when there is a similar distance travel route in the transmission source travel history information stored in the travel history storage unit 26. Then, the corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, if it is determined in step S610 described above that there is no similar distance travel route, the process proceeds to step S614. In step S614, the history statistical processing unit 27 stores the transmission source travel stored in the travel history storage unit 26. It is determined whether or not there is a similar average speed travel route in the history information (travel route). As the similar average speed travel route, for example, there is a travel route having the same or similar average speed as the presentation route (similar route, similar composite route) determined in step S403 or S404 described above.

  If the presented route (similar route, similar combined route) cannot be determined in steps S403 and 404 described above, the planned route searched in step S401 described above is set as the similar average speed travel route. For example, the history statistical processing unit 27 has a difference from the average speed of the presented route in the transmission source travel history information (travel route) stored in the travel history storage unit 26 as a set value (for example, ± 5 km / h). ) Determine whether there are less travel routes. If the history statistical processing unit 27 determines that there is a similar average speed travel route (step S614 = Yes), the history statistical processing unit 27 proceeds to step S615. On the other hand, when the history statistical processing unit 27 determines that there is no similar average speed travel route (step S614 = No), the history statistical processing unit 27 proceeds to step S618.

  If it is determined in step S614 that there is a similar average speed travel route, the process proceeds to step S615. In step S615, the history statistical processing unit 27 displays the transmission source travel history information stored in the travel history storage unit 26. Referring to this, power consumption per unit distance of the similar average speed travel route (hereinafter also referred to as similar average speed power consumption rate) is calculated.

  Subsequently, the process proceeds to step S616, where the history statistical processing unit 27 multiplies the similar average speed power consumption rate calculated in step S615 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S617, the history statistical processing unit 27 corrects the power consumption calculated in step S407 or S408 described above based on the power consumption for correction calculated in step S616 described above. The power consumption correction method can be the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. Thereby, the history statistical processing unit 27 calculates the power consumption at the similar average vehicle speed power consumption rate when there is a similar average speed travel route in the transmission source travel history information accumulated by the travel history accumulation unit 26. The corrected power consumption is transmitted (provided) to the transmission source terminal device 2.

  On the other hand, if it is determined in step S614 described above that there is no similar average speed travel route, the process proceeds to step S618. In step S618, the history statistical processing unit 27 stores the transmission source stored in the travel history storage unit 26. With reference to the travel history information, an average value of power consumption per unit distance (hereinafter also referred to as an average power consumption rate) of the travel route of all transmission source travel history information is calculated.

  Subsequently, the process proceeds to step S619, and the history statistical processing unit 27 multiplies the average power consumption rate calculated in step S618 described above by the total length of the planned route. Then, the history statistical processing unit 27 sets the multiplication result as power consumption for correction.

  In step S620, the history statistical processing unit 27 corrects the power consumption calculated in step S407 or S408 described above based on the power consumption for correction calculated in step S619 described above. The power consumption correction method can be the same as that in step S605 described above. Subsequently, the history statistical processing unit 27 sets the corrected power consumption as the corrected power consumption, and ends the power consumption correction process. As a result, the history statistical processing unit 27 corrects the power consumption with the average power consumption rate when all the determinations of the above-described steps S603, S606, S610, and S614 are “No”, and the corrected consumption The power is transmitted (provided) to the transmission source terminal device 2.

  Returning to FIG. 6A, when the power consumption correction process is completed, the process proceeds to step S412. The history statistical processing unit 27 extracts the presentation route (similar route, similar synthesis route) determined in step S403 or S404 described above, and extracted in step S410 described above. After transmitting (providing) the information on the charging point and the power consumption corrected in step S411 described above to the transmission source terminal device 2, the travel history statistical processing is terminated. Note that if the presented route cannot be determined in steps S403 and 404 described above, the history statistical processing unit 27 determines the planned route searched in step S401 described above, the charging via point extracted in step S410 described above, and the above-described route. Information on the power consumption (theoretical power consumption) calculated in step S408 is transmitted. The history statistical processing unit 27 also transmits (provides) a control command to display the unreachable warning to the transmission source terminal device 2 when it is determined to perform the unreachable warning in step S410 described above.

  In the present embodiment, an example of transmitting (providing) the information about the charging via point extracted in step S410 described above and the power consumption corrected in step S411 described above to the transmission source terminal device 2 has been described. A configuration can also be adopted. For example, it is good also as a structure which transmits (provides) the information of the power consumption point before correction | amendment by step S406 or S409 mentioned above acquired in step S406 or S409 mentioned above.

  As described above, in the present embodiment, the history statistics processing unit 27 searches for the planned route based on the first driving history information of the designated driver among the first driving history information stored in the driving history storage unit 26. The power consumption consumed when driving is calculated. Subsequently, the history statistical processing unit 27 corrects the extracted power consumption based on the calculated power consumption. Subsequently, the history statistical processing unit 27 provides corrected power consumption information. Therefore, it is possible to acquire power consumption considering the driving characteristics of the driver. Therefore, more appropriate power consumption information can be provided.

  As described above, in the present embodiment, the vehicle information providing device 3 sequentially acquires at least one of travel position information, power consumption information, and charge position information from the in-vehicle device 1 of the vehicle A that uses the electric motor 13 as a drive source. And stored as travel history information (first travel history information, second travel history information). Then, the vehicle information providing device 3 refers to the accumulated first traveling history information, searches for similar routes and similar synthetic routes that are the same as or similar to the planned route, and presents the detected similar routes and similar synthetic routes. Determine as. Subsequently, the vehicle information providing apparatus 3 refers to the accumulated first traveling history information and second traveling history information, and consumes power when traveling on the determined presentation route (similar route, similar combined route). In addition, it detects a charging via point when traveling along a presentation route (similar route, similar synthetic route). Subsequently, the vehicle information providing device 3 provides information on the determined presentation route (similar route, similar combined route), and information on the determined power consumption and charging via point. For this reason, it is possible to provide power consumption information and charging route information according to the actual environment.

  In the present embodiment, the vehicle information providing apparatus 3 determines (extracts) both the power consumption and the charging via point consumed when the vehicle A actually travels the presented route (similar route, similar combined route). Although an example is shown, other configurations may be employed. For example, the vehicle information providing apparatus 3 may be configured to determine at least one of power consumption and a charging via point. In this case, the vehicle information providing device 3 provides (transmits) only the determined power consumption or the charging via point together with the presentation route (similar route, similar combined route).

Further, according to the present embodiment, the vehicle information providing device 3 sequentially acquires at least one of travel position information, power consumption information, and charge position information from the in-vehicle device 1 of the vehicle A using the electric motor 13 as a drive source. Accumulated as travel history information (first travel history information, second travel history information). Then, the vehicle information providing device 3 refers to the accumulated first travel history information, refers to the information on the start point and end point of each travel route included in the first travel history information, and determines the end point and start point. DOO synthesizes the route together within predetermined composite point range R _S, to generate a synthetic route. Furthermore, vehicle information providing device 3, from the starting point P _O to the target point P _D planned route the same or similar similar route, and from the starting point P _O to the target point P _D planned route identical or similar to A synthetic route is searched and determined as a presentation route. Subsequently, when the vehicle information providing device 3 refers to the accumulated first traveling history information and second traveling history information and travels the power consumption and the presenting route that are consumed when traveling the determined presenting route. Detect the via-charging point. Subsequently, the vehicle information providing apparatus 3 provides information on the determined presentation route, and at least one information on the determined power consumption and charging via point.

Therefore, according to the present embodiment, referring to the travel history information, that is, the information obtained by actually traveling the vehicle A, the power consumption and the charging via point consumed when the vehicle A travels are determined. As a result, it is possible to provide power consumption information according to the actual environment and information on the charging via point. In particular, according to the present embodiment, when determining the presented route, in addition to the travel route (single travel route) on which one vehicle traveled at a time, the end point and the start point have a predetermined composite point range R. _Since the combined route generated by combining the traveling routes in _S is also a search target, a more appropriate presented route can be determined. As a result, it is possible to provide information on the power consumption and the information on the charging via point that more closely match the actual environment.

  In particular, according to the present embodiment, in the similar route search process, the number of end points of the travel data stored in the travel history storage unit 26 is determined, and the corresponding travel data is first extracted for the end points with a small number of data, Since it is determined whether the other end point corresponds to the extracted travel data, a similar route can be extracted with a minimum search load.

  In addition to this, when extracting a travel route that passes through a specific transit area, it is necessary to perform a search for a travel route that includes a large amount of information such as a latitude / longitude sequence or a road link sequence. Although the load increases and the search time takes a long time, in this example, the search for such a travel route is performed for a limited travel route with a narrowed start point and end point, so the minimum search load It is possible to extract a travel route similar to the planned route including the waypoint.

  In addition, when extracting a travel route that passes through a specific transit area, it is necessary to perform a search for a travel route that includes a large amount of information such as a latitude / longitude sequence or a road link sequence, which increases the search load. In this embodiment, in addition to performing a search for such a travel route for a limited travel route with a narrowed start point and end point, there are a plurality of waypoints. If it is set, narrowing down is started from the waypoints where the number of passing data is small, so it is possible to extract a travel route similar to a planned route including a plurality of waypoints with a minimum search load.

  Further, according to the present embodiment, in the similar synthetic route search process, even if a single travel route does not hit, a plurality of travel routes are narrowed inductively so as to reduce the search load. The same or similar traveling route can be presented as a combined route.

<< Second Embodiment >>
Next, a second embodiment of the present invention will be described.
In the second embodiment, in the vehicle information providing system S shown in FIG. 1, as described below, when a plurality of travel routes traveled by the same vehicle are combined and a combined route is generated, the end point is determined. In addition to having a circular range having a radius r _S having a starting point in the synthesis point range R _S , the requirement is that the running conditions of the running routes to be synthesized are within a predetermined range. Except for the difference from the first embodiment, the second embodiment has the same configuration as that of the first embodiment described above and exhibits the same function.

That is, for example, when the scene shown in FIG. 10A is illustrated, in this scene example, a circular range having a radius r _S from the end point of “travel route 1 of vehicle A ₁ ” is represented as a composite point range R _S. travel route having a start point within are present two as the "traveling route 4 of the vehicle a _1", "traveling route 2 of the vehicle a _1". Then, in this situation, for example, when the running condition of "traveling route 2 of the vehicle A _1" is, the running condition of "traveling route 1 of the vehicle A _1", is within a predetermined range, running history accumulation unit 26 combines these to produce a synthesis route consisting of a "vehicle a ₁ of the travel route 1" and "traveling route 4 of the vehicle a _1". However, on the other hand, the running condition of "traveling route 4 of the vehicle A _1" is, the running condition of "traveling route 1 of the vehicle A _1", if not within a predetermined range, the travel history accumulation unit 26 Will not synthesize these.

In the present embodiment, the traveling condition includes at least one condition of traveling time zone, traveling speed, traveling altitude, day of the week, season, temperature, weather, and power consumption of the air conditioner. For example, the conditions of “traveling time zone” will be described as an example. For example, the “traveling time zone” of “traveling route 1 of vehicle A ₁ ” is AM7 to AM8. When the “traveling time zone” of the traveling route 2 of the vehicle A ₁ is from 8:00 am to 9:00 am, it can be determined that the congestion situation of these roads is equivalent and the traveling conditions are relatively close, Therefore, for example, in such a case, a synthesis route is generated. On the other hand, for example, "running time" of the "traveling Route 4 of the vehicle _{A 1"} is, in the case of at PM10 o'clock ~PM11 is, for the "traveling Route 1 of vehicle _{A 1",} congestion of the road Since the situation is likely to be different, it can be determined that the traveling conditions are relatively different. For this reason, for example, in such a case, a combined route is not generated. In particular, since there is a high possibility that the power consumption differs between travel routes with relatively different travel conditions in this way, it may be difficult to obtain power consumption information in accordance with the actual environment. Therefore, in this embodiment, in such a case, a synthesis route is not generated.

  As for the driving conditions other than the “traveling time zone”, for example, regarding the condition of “day of the week”, even if the driving time zone is the same, Monday to Friday and Saturday and Sunday have different road congestion conditions. Conceivable. Furthermore, regarding “seasonal” conditions, “temperature” conditions, and “weather” conditions, if these conditions are different, the power consumption of the air conditioner will be different, so the power consumption is likely to be different. . Therefore, in the present embodiment, the travel history accumulation unit 26 considers such travel conditions, and does not generate a combined route when the travel conditions are not within a predetermined range.

  In addition, in the present embodiment, the travel history accumulating unit 26 compares the travel conditions of the travel routes used for the composition for each composite route even when generating the composite route, and the approximate degree of the travel condition is obtained. Accordingly, the priority P is set. That is, for example, even if the travel conditions of the travel routes used for the composition are within a predetermined range, if the travel condition between the travel routes used for the composition is relatively large, the travel is performed on the obtained composite route. In this case, the accuracy of the power consumption information is determined to be relatively low, and the priority P is set low. On the other hand, if the difference in travel conditions between the travel routes used for composition is relatively small, it is judged that the accuracy of the power consumption information when traveling on the obtained composite route is relatively high, and the priority Set P high.

Then, as a result of searching for a similar synthetic route that is the same as or similar to the planned route in step S404 described above, the history statistics processing unit 27 has a plurality of similar synthetic routes (the starting point is within the departure area R _O , and When a combined route having an end point in the destination area _RD is detected, the route is determined as a presentation route with priority from the highest priority P among the detected similar combined routes. In other words, in the present embodiment, a predetermined number of similar synthesis routes with a high priority P are determined as presentation routes. Or when determining a presentation route, it is good also as a structure which considers whether it is close to the present conditions in addition to the priority P. FIG.

  In the present embodiment, for example, when the travel conditions of the travel routes constituting the composite route are the same date and time and the time zone is relatively similar, the travel history corresponding to such travel route Can be determined as constituting a single itinerary, while taking a break or charging, the priority P can be set highest for such a combined route. In this case, for example, the time difference between the combined travel routes (the difference between the time at the end of the travel and the time at the start of the subsequent travel) is within a predetermined time (for example, within one hour). And a method for referring to the charging time information included in the second travel history information.

According to the second embodiment described above, the following effects are obtained in addition to the effects of the first embodiment described above. That is, according to the second embodiment, when a plurality of travel routes traveled by the same vehicle are combined and a composite route is generated, a circular range having a radius r _S from the end point is included in the composite point range R _S. In addition to having a starting point at the same time, since it is a requirement that the traveling conditions of the traveling routes to be combined are within a predetermined range, more accurate information can be obtained as a similar synthetic route that is the same as or similar to the planned route. It is possible to appropriately obtain what includes (including information on power consumption with higher accuracy). As a result, it is possible to provide information on the power consumption and the information on the charging via point that more closely match the actual environment.

In addition to this, according to the second embodiment, when a plurality of similar composite routes having a start point in the departure area R _O and having an end point in the destination area R _D are detected, Since the presentation route that is actually presented is determined based on the priority P that represents the approximation of the driving condition, more accurate power consumption information and charging via point information can be provided.

<< Third Embodiment >>
Next, a third embodiment of the present invention will be described.
In the third embodiment, in the vehicle information providing system S shown in FIG. 1, as described below, when generating a combined route, in addition to a plurality of travel routes traveled by the same vehicle, a plurality of different routes It has the same configuration as the first embodiment described above except that it differs from the first embodiment in that a plurality of travel routes on which the vehicle has traveled are combined.

That is, in this embodiment, as shown in FIG. 14 (A), when generating the synthetic route, a circular range with a with a radius r _S from the end point of the "traveling route 1 of the vehicle A _1" If there is a start point of “travel route 6 of vehicle A ₂ ” that is the travel route of other vehicle A ₂ in composite point range R _S , travel history storage unit 26 combines these and creates “vehicle A combined route of “travel route 1 of A ₁ ” and “travel route 6 of vehicle A ₂ ” is generated.

Also in this case, as shown in FIG. 14B, the travel history accumulating unit 26 synthesizes a “travel route 7 of the vehicle A ₃ ” that is a travel route of another vehicle A ₃ to 3 One of the vehicle a _1, a _2, a ₃ of the travel route may be a such a manner as to generate a synthesized formed by synthetic routes.

Furthermore, also in the present embodiment, when generating a synthesis route, as in the second embodiment described above, a circular range having a radius r _S from the end point is set within the synthesis point range R _S. In addition to having it, it is desirable to make it a requirement that the traveling conditions of the traveling routes to be combined are within a predetermined range. In particular, when a plurality of travel routes traveled by a plurality of different vehicles are to be combined, the number of travel routes that can be combined is relatively large, and there is a high possibility that the difference in travel conditions becomes large. There is a tendency. For this reason, in the present embodiment, it is desirable to consider that such a point is taken into consideration when generating a combined route that the traveling conditions of the combined traveling routes are within a predetermined range. As a result, a combined route that increases the difference in traveling conditions is not generated, and the accuracy of the obtained combined route can be ensured.

In addition, in the present embodiment, as in the second embodiment described above, for each combined route, the traveling conditions of the traveling routes used for the composition are compared, and the priority P is set according to the approximate degree of the traveling conditions. Set. In addition to this, as in the second embodiment described above, as a result of searching for a similar synthetic route that is the same as or similar to the planned route in step S404, a plurality of similar synthetic routes (within the departure area R _O ) are searched. If a composite route having a start point and having an end point in the destination area _RD is detected, priority is given to the one having a higher priority P among a plurality of detected similar composite routes. To determine the presentation route.

  In the present embodiment, when setting the priority P of the composite route, when the travel route used for composition is a travel route of the same vehicle, it is a travel route of a plurality of different vehicles. The priority P is set higher than In particular, when the combined route is a combination of the traveling routes of the same vehicle, the driving tendency is almost the same, so compared with the combined route of the plurality of different vehicles, It can be determined that the information includes highly accurate information (including more accurate power consumption information). Therefore, in this embodiment, the priority P is set high in such a case.

  According to the third embodiment described above, in addition to the effects of the first embodiment and the second embodiment described above, the following effects are provided. That is, according to the third embodiment, when generating a combined route, in addition to a plurality of traveling routes traveled by the same vehicle, a plurality of traveling routes traveled by a plurality of different vehicles are targeted for synthesis. It is possible to generate a relatively large amount of synthesis route data. Since such a relatively large number of generated synthetic routes are to be searched, a more appropriate presentation route can be determined. As a result, it is possible to provide information on the power consumption and the information on the charging via point that more closely match the actual environment.

  As mentioned above, although embodiment of this invention was described, these embodiment was described in order to make an understanding of this invention easy, and was not described in order to limit this invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

For example, in the embodiment described above, in accordance with the distance between the starting point P _O and destination point P _D, changes the size of the starting region R _O and the destination area R _D (as the distance is long, increase) the manner or, alternatively, depending on the required time (travel time) to reach from the departure point P _O to the destination P _D, the longer the departing area R _O and purpose to change the size of the region R _D (time required, (Enlarge).

  In the above-described embodiment, the history statistical processing unit 27 refers to the first travel history information stored in the travel history storage unit 26 and travels along the presented route (similar route, similar composite route). The power consumption may be determined for each driver. In this case, the history statistics processing unit 27 transmits information on the maximum power consumption, the minimum power consumption, and the average power consumption among the determined power consumptions for each driver together with the information on the presentation route and the charging route point. Transmit (provide) to the former terminal device 2. As a result, as shown in FIG. 15, the source terminal device 2 adds the maximum power consumption (power consumption MAX) and the minimum power consumption (power consumption MIN) in addition to the presentation route and the charging route point based on the received information. ) And average power consumption (average power consumption) are displayed on the display screen. In particular, according to such a configuration, the power consumption when driving the presented route is calculated for each driver, and the maximum power consumption, the minimum power consumption, and the average power consumption among the calculated power consumptions are calculated. provide. Therefore, the user can grasp the degree of variation in power consumption for each driver.

In the above-described embodiment, an example in which the display unit 24 displays the power consumption and the charging via point together with the presentation route (similar route, similar combined route) has been described. However, other configurations may be employed. For example, the display unit 24 includes the presence / absence of traffic congestion, travel speed, travel altitude, season, temperature, weather, travel time zone included in the first travel history information and the second travel history information used to extract power consumption and charging via points, It is good also as a structure which displays the information of driving power consumption and the power consumption of an air conditioner collectively. Specifically, the terminal device 2 has at least one of the presence / absence of traffic jam, travel speed, travel altitude, season, temperature, weather, travel time zone, travel power consumption, and air conditioner power consumption (hereinafter also referred to as search state quantity). ). Subsequently, the terminal device 2 transmits information on the received search state quantity to the vehicle information providing device 3. Subsequently, when the vehicle information providing apparatus 3 (history statistical processing unit 27) receives the information transmitted by the terminal apparatus 2, the search condition state quantity is acquired as a search condition from the received information. Subsequently, when the history statistics processing unit 27 refers to the travel history information that matches the acquired search condition among the travel history information accumulated by the travel history accumulation unit 26, The power consumption to be consumed and the charging via point to be passed when traveling along the presentation route are determined. Subsequently, the history statistical processing unit 27 transmits (provides) the acquired search condition information to the transmission source terminal device 2 together with the information of the presentation route (similar route, similar combined route), power consumption, and charging route point. Thereby, as shown in FIG. 16, the transmission source terminal device 2 displays the search conditions used for determining the power consumption and the charging via point in addition to the presentation route, the power consumption and the charging via point based on the received information. Display on the screen.
According to such a configuration, the search conditions used for determining the power consumption and the charging via point are provided together with the presentation route, the power consumption and the charging via point. Therefore, the user can grasp the search conditions used for determining the power consumption and the charging via point.

In the above-described embodiment, an example in which a similar synthetic route is searched from the synthetic routes regardless of whether or not a similar route is detected is illustrated. However, only when a similar route is not detected, the similar route is searched. A synthetic route is searched, and when a similar synthetic route having a start point in the departure area R _O and an end point in the destination area R _D is detected as a result of the search, this route is presented. It is good also as a structure determined as. In particular, in this case, since the similar synthetic route is searched only when the similar synthetic route needs to be searched, the calculation load can be reduced.

In addition, when generating a composite route, the end point of any travel route is located in an area corresponding to a large-scale facility (for example, a large store or an amusement spot) of a predetermined size or larger, or a public route When located within the area of the chargeable facility including the charging facility, these areas, that is, the area of the large-scale facility and the area of the chargeable facility may be set as the synthesis point range R _S. In particular, such large-scale facilities and rechargeable facilities use a large number of vehicles. Therefore, by setting the range of such facilities as the combination point range R _S , it is possible to compare combined routes that are relatively close to driving conditions. It is possible to generate as many as possible. In addition, the information of the area | region of a large-scale facility and the area | region of a chargeable facility can be used by memorize | storing beforehand in the map information storage part 25, for example.

Furthermore, in the above-described embodiment, when setting the priority P, in addition to the approximate degree of the travel condition or instead of the approximate degree of the travel condition, the end point at the composite point of the combined travel route, The priority P may be set according to the distance from the start point. That is, when the distance between the end point and the start point at the combined point of the combined travel route is relatively close, the priority P is set high, while when these distances are relatively far, Set the priority P low. In particular, when the distance between the end point and the start point at the composite point of the combined travel route is relatively close, the error in power consumption corresponding to these distance gaps is relatively small. While increasing the priority P of the route, if these distances are relatively long, the power consumption error corresponding to these distance gaps becomes relatively large. Therefore, the priority P of such a combined route is decreased. Thus, it is possible to appropriately provide information including information with higher accuracy (including information on power consumption with higher accuracy).

  Further, in the present embodiment, when setting the priority P, in addition to the approximate degree of the travel condition or instead of the approximate degree of the travel condition, it starts from the end point at the composite point of the combined travel route. The priority P may be set according to the required time (traveling time) to reach the point (the shorter the required time, the higher the priority P).

  Furthermore, in the above-described embodiment, when setting the priority P, the travel route including a specific point such as the home position of the driver of the vehicle A is detected, and the travel route including such a specific point is used. For the combined route, the priority P may be set relatively low. In particular, idling is performed at the home position, and power consumption tends to increase when traveling toward the home position, so the travel route has the home position as the starting point or end point. In the case of providing, there is a tendency to increase the number of information including information with low accuracy (including information about power consumption with low accuracy). Therefore, in such a case, the priority P is set to be relatively low, thereby appropriately providing information including information with higher accuracy (including information of power consumption with higher accuracy). be able to. In addition, as a method of determining whether or not the travel route includes a specific point such as a home position, for example, the start point information, the end point information, and the date and time at the start of the travel included in the first travel history information. Refer to the information and information on the date and time at the end of travel, etc., and the location where the stay frequency or stay time is equal to or greater than a predetermined threshold (a location where the stay frequency is relatively high or a location where the stay time is relatively long (for example, The stay time can be determined by detecting 12) or more)).

  The history statistical processing unit 27 of the vehicle information providing device 3 in the above-described embodiment corresponds to the planned route acquisition unit, the presentation route determination unit, and the presentation information provision unit of the present invention.
