Description

  The present invention relates to an information processing apparatus for a vehicle and an information processing system.

In recent years, electric vehicles (hereinafter referred to as “EV vehicles”) are expected to be widely used from the viewpoint of conservation of the global environment and resource saving. For EV vehicles, the energy cost per unit distance can be made extremely low compared to the case where an internal combustion engine is used, and the use of clean energy such as sunlight and wind as an energy source reduces CO ₂ emissions as much as possible. There are advantages such as being able to approach zero.

  However, the issues for the spread of EV vehicles are the length of time for charging the in-vehicle power storage device and the short travelable distance per charge.

  The charging time required to make the remaining battery capacity of the in-vehicle power storage device 80% is about 30 minutes using a quick charger that is currently popular. Since this charging time corresponds to about 5 to 6 times the gasoline refueling time, the EV vehicle charging time is long.

  Moreover, the travelable distance per EV vehicle charge is less than 200 km, and may be further shortened depending on the accelerator operation and the use condition of the air conditioner. Therefore, since the travelable distance of the EV vehicle does not reach the travelable distance of a gasoline vehicle full of fuel, the travelable distance per charge is short.

  Therefore, considering that the EV vehicle has a short driving distance per charge, at present, when using the vehicle, it is indispensable to appropriately charge in the middle of the route to the destination. .

  In view of the long charging time of the EV vehicle, it is necessary to appropriately select a charging facility that can quickly start charging in order to reach the destination in the shortest possible time. In order to select an appropriate charging facility, it is necessary to consider the travel distance with respect to the remaining battery capacity and the usage status of the charger installed in the charging facility.

  Therefore, a technique for providing information on the availability of a charger installed in a charging facility has been proposed. As the technique, for example, a charging information providing device that provides information on a charging facility that can start charging immediately after arrival is disclosed (see, for example, Patent Document 1).

  The invention disclosed in Patent Document 1 provides information on a charger that can start charging immediately or within a predetermined time after arriving at a charging facility.

  In addition, the charger installed at the charging facility was usable when the charging facility was selected, but when it arrives at the charging facility, the charger is used by another vehicle, and the problem that charging cannot be started quickly is solved. Therefore, an information providing system in consideration of other vehicle trends has been disclosed (for example, see Patent Document 2).

  The invention disclosed in Patent Document 2 predicts the congestion state of the charging facility at the time when the host vehicle arrives at the charging facility based on the position information of other vehicles and the remaining battery level.

In particular, the information processing system 200 according to the first embodiment of the present invention distributes vehicles on which the information processing device 211 according to the first embodiment of the present invention is mounted to charging facilities. Useful in that it can.

  The vehicle information processing system 200 according to the present embodiment can include an EV vehicle information database (not shown) that stores information related to other EV vehicles that can communicate with the center 220. More specifically, the information related to other EV vehicles includes position information of other vehicles and remaining battery capacity. The server A can predict the trends of other vehicles by referring to the vehicle information stored in the EV vehicle information database.

  In the information processing system 200 according to the first embodiment of the present invention, the charging facility selecting device 221 is provided in the center 220 that is outside the EV vehicle 1, and the charging facility selecting device 221 is an EV vehicle. 1 may be mounted. In this case, the information processing system 200 and the charging facility selection device 221 are configured to be electrically connected.

  As illustrated in FIG. 2, the information processing system 200 according to the first exemplary embodiment of the present invention includes an information processing device 211. The information processing apparatus 211 according to the first embodiment of the present invention is mounted on the EV vehicle 1.

  The information processing apparatus 211 includes an in-vehicle communication unit 9, a charging facility information acquisition unit 212, a travelable distance calculation unit 213, a driving characteristic generation unit 214, a driving action history DB 121, and the display unit 10.

  The ECU 100 executes processing performed in the selected charging facility acquisition unit 212, the travelable distance calculation unit 213, the driving characteristic generation unit 214, and the driving behavior history DB 121. The in-vehicle communication unit 9 and the display unit 10 are the same as those described in FIG. 1, and are as described above. The ECU 100 executes various processes performed by the information processing device 211.

  The information processing device 211 transmits at least a request for information about the selected charging facility and driving characteristic information to the charging facility selecting device 221 provided outside the vehicle. Next, the information processing apparatus 211 receives information on the charging facility selected based on the driving characteristic information from the charging facility selecting apparatus 221. Then, the information processing apparatus 211 displays information on the charging facility on the display unit 10, and guides the charging facility to the driver.

  The charging facility information acquisition unit 212 sends the driving characteristic information detected by the driving characteristic generation unit 214 to the charging facility selection device 221 and requests information on the selected charging facility. When the charging facility information acquisition unit 212 acquires information about the selected charging facility from the charging facility selection device 221, the charging facility information acquisition unit 212 transmits the information to the display unit 10 in order to display the information on the display unit 10.

  The timing for requesting information on the selected charging facility is not particularly limited, and it may be when the IG 113 is turned on, when a destination is input, or at any timing of the driver. Further, it may be regular at regular intervals. In the case of arbitrary timing, for example, the driver can request the information by operating the input unit 11.

  The travelable distance calculation unit 213 calculates the travelable distance based on the remaining battery capacity. For example, the travelable distance can be calculated by applying the travel distance per unit of battery capacity stored in the driving behavior history DB 121 to the current remaining battery capacity. The ECU 100 executes processing performed by the travelable distance calculation unit 213.

  The travelable distance calculation unit 213 can calculate the travelable range by further applying the calculated travelable distance to the position information of the host vehicle. If the travelable range is placed on a map based on the position of the host vehicle and displayed on the display unit 10, the driver can quickly recognize the actual travelable range.

  The process for calculating the travelable range from the travelable distance may be executed by the server A in the charging facility selecting apparatus 221 when the charging facility selecting apparatus 221 receives information on the travelable distance.

  The driving action history DB 121 stores driving action histories such as the remaining battery capacity immediately before charging, the travel route (link ID), the travel distance, and the travel time by the ECU 100.

  The remaining battery capacity immediately before charging is stored according to the flow of FIG. Specifically, ECU 100 stores the SOC calculated based on the integrated value of the charge / discharge current detected by the current sensor in driving behavior history DB 121.

  The travel route is recorded, for example, as a link ID assigned to a road in a certain section. Specifically, the ECU 100 stores each link ID related to the road on the travel route in the driving action history DB 121 based on the map information obtained from the map information DB.

  The travel distance is stored, for example, by accumulating distances according to the travel route. Specifically, the ECU 100 adds information obtained from various sensors as needed to the map information obtained from the map information DB, accumulates the travel distance, and stores it in the driving action history DB 121.

  The travel time is stored, for example, as the time counted when the vehicle is traveling by the clock function of the ECU 100. Specifically, the ECU 100 counts the time from the start of travel to the time of IG-OFF and stores it in the driving action history DB 121.

  The driving behavior history includes information that can analyze, for example, the width of the road that has traveled, whether or not a side road is used, the number of right turns, and the presence or absence of a U-turn. Furthermore, information that can analyze whether or not charging has been executed in the expressway (such as a service area) when the expressway is used is included.

  The road width of the traveled road is stored, for example, by detecting the road width of the travel road from the map information. Specifically, the ECU 100 detects the road width of the running road from the map information obtained from the map information DB, and stores it in the driving action history DB 121. If road width information is associated with the link ID, the ECU 100 records the link ID related to the road on the travel route and also stores the road width in the driving action history DB 121. Information such as whether the road is flat or steep is similarly detected and stored.

  The presence / absence of the use of the side road is stored by detecting whether or not a side road defined as a side road is passed in the map information. Specifically, the ECU 100 stores in the driving behavior history DB 121 that the side road is used when the map information obtained from the map information DB passes through a road defined as a side road in advance. The ECU 100 stores it every time the side road is used. Therefore, the ECU 100 can calculate the cumulative number of times using the side road from the information in the driving action history DB.

  The number of right turns is detected and stored by, for example, a right turn counter. Specifically, ECU 100 senses a right turn with various sensors, counts it with a right turn counter function of ECU 100, and stores it in driving action history DB 121.

  The presence or absence of the U-turn is detected and stored by, for example, a U-turn counter. Specifically, ECU 100 senses a U-turn with various sensors, counts it with a U-turn counter function of ECU 100, and stores it in driving action history DB 121.

  Whether or not charging has been executed in the expressway (such as a service area) is stored using, for example, a flow of FIG. 4 described later with reference to map information. Specifically, the ECU 100 grasps whether or not the vehicle is on the expressway from the position information of the own vehicle obtained by the GPS sensor and the map information obtained from the map information DB, and charging is executed according to the flow of FIG. When this is detected, the fact that the vehicle has been charged in the expressway is stored in the driving action history DB 121.

  The driving characteristic generation unit 214 generates driving characteristic information based on the driving action history stored in the driving action history DB 121. The driving characteristic related to the driving characteristic information generated by the driving characteristic generation unit 214 is, for example, the charge execution timing for the remaining battery capacity or the characteristics of the route traveled in the past. The ECU 100 executes processing performed by the driving characteristic generation unit 214. Therefore, the ECU 100 constitutes an operation characteristic analysis unit.

  The characteristics related to the timing of charge execution with respect to the remaining battery capacity are, for example, the case where the charge is executed in the past when the remaining battery capacity is relatively large, for example, 40% or more, or the remaining battery capacity is, for example, 40 Whether or not charging was performed when the amount was relatively low, such as less than%.

  Considering this characteristic, a driver who has a preference to perform charging when the remaining battery capacity is relatively large should be relatively distant from the current position to perform charging before the remaining battery capacity decreases. Information on nearby charging facilities is provided. In addition, for drivers who have a preference to perform charging when the remaining battery capacity is relatively small, a charging facility that is relatively close to the current position in order to perform charging after the remaining battery capacity becomes low Information about is provided. This can prevent the vehicle from concentrating on a specific charging facility.

  The characteristics related to the characteristics of the route traveled in the past are, for example, when considering the route traveled in the past, for example, the road width is wide or flat, no side roads are used, or the traffic volume is relatively small. You prefer “routes that make it easy to drive a vehicle”, or you do n’t mind a relatively “route that makes it difficult to drive a vehicle”, for example, the road is narrow or steep, uses a side road, or has a lot of traffic. Or that.

  If this characteristic is taken into account, the charging facility that is on the path that is relatively easy to drive the vehicle is referred to for a driver who likes the route that easily drives the vehicle by referring to the route from the current position to the charging facility. The information about the charging facility on the route that is relatively difficult to drive the vehicle is provided to the driver who has the preference that does not hesitate even on the route that is difficult to drive the vehicle. For example, if there are other merits such as a charging facility on a route where it is difficult to drive the vehicle and charging can be started quickly with fewer users, the preference that does not hesitate even on a route that is difficult to drive the vehicle. It is beneficial for the driver who has it. This can prevent the vehicle from concentrating on a specific charging facility.

  As shown in FIG. 2, the information processing system 200 according to the first embodiment of the present invention includes a charging facility selection device 221. The charging facility selection device 221 is installed in a center 222 outside the vehicle.

  The charging facility selecting device 221 includes a center side communication unit 222, a charging facility selecting unit 223, a traffic information database (hereinafter referred to as “traffic information DB”) 224, a charging facility information database (hereinafter referred to as “charging facility information DB”). )) 225. The center 220 includes a server A. The server A executes various processes performed by the charging facility selection device 221.

  The charging facility selection device 221 receives at least a request for selected charging facility information and driving characteristic information from the information processing device 211. Next, the charging facility selection device 221 selects a charging facility based on the driving characteristic information. Then, the charging facility selection device 221 transmits information regarding the selected charging facility to the information processing device 211.

  The center side communication unit 222 receives the information transmitted from the in-vehicle communication unit 9 and sends the information to the charging facility selection unit 223. Then, the center-side communication unit 222 transmits information regarding the selected charging facility sent from the charging facility selecting unit 223 to the in-vehicle communication unit 9. The server A executes processing performed by the center side communication unit 222.

  The charging facility selection unit 223 selects a charging facility from the charging facility group based on the driving characteristic information received from the information processing apparatus 211. Since the driving characteristic information is information indicating the driver's preference, in other words, the charging facility selection unit 223 selects a charging facility that matches the driver's preference. Therefore, the selected charging facility is a charging facility that suits the driver's preference as compared with other charging facilities. The selected charging facility is a charging facility selected from the charging facility group. Server A executes processing performed by charging facility selection unit 223. Therefore, the server A constitutes a charging facility selection unit.

  Note that the charging facility selection unit 223 preferably acquires necessary information from one or both of information related to the charging facility stored in the charging facility information DB 225 and traffic information stored in the traffic information DB 224, and stores the information. In consideration of this, the charging facility is selected.

  In addition, the charging facility selection unit 223 can make a determination such as reducing the frequency of providing the charging facility when the destination is close and the current remaining battery capacity can be reached without any problem. In addition, if the destination can be reached sufficiently, but the charging facility near the destination is congested, or if the vicinity of the destination is heavily congested, a decision such as guiding the charging facility in front of it will be made. It can also be added.

  The traffic information DB 224 is a DB that accumulates traffic information such as road congestion and accident information. The traffic information fluctuates in real time. Therefore, the traffic information DB 224 is generally configured to update the information in the traffic information DB 224 to the latest information by acquiring the latest traffic information from the information providing company 400 via the network 300. The ECU 100 supplies traffic information from the traffic information DB 224 in response to a request from the charging facility information selection unit 223.

  The charging facility information DB 225 is a database in which information related to a large number of charging facilities is accumulated. Information related to charging facilities includes, for example, the location of the charging facility, the type and number of chargers installed in the charging facility, or the charging facility such as the usage status, usage end time or usage reservation status of the charger. The charger usage status. Information related to the charging facility such as the charger usage status provided in the charging facility such as the usage status, usage end time or usage reservation status of the charger varies in real time. Therefore, the charging facility information DB 225 generally has a configuration in which information in the charging facility information DB 225 is updated to the latest information by acquiring information on the latest charging facility from the information providing company 400 via the network 300. ing. The ECU 100 supplies charging facility information from the charging facility information DB 225 in response to a request from the charging facility information selection unit.

  As a charging facility selection unit, the server A determines whether the vehicle has a high degree of urgency for charging based on the received information. The urgency of charging is determined by comprehensively determining vehicle position information, travelable distance information or travelable range information, route information to the destination, charging facility position information, and the like. For example, when it is assumed that the vehicle travels a route toward the destination, the urgency of charging is high when there are fewer charging facilities in the driving range or there are no charging facilities in the range. Is determined.

  As illustrated in FIG. 2, the information processing system 200 according to the first exemplary embodiment of the present invention includes an information providing device 401. The information providing apparatus 401 is installed in the information providing destination company 400. The information providing company 400 includes a server B. The server B executes various processes performed by the information providing apparatus 401.

  As the information providing device 401, the server B transmits the traffic information and the charging facility information that change in real time as described above to the charging facility selection device 221 via the network 300. The server A in the charging facility selection apparatus 221 accumulates the received information in the traffic information DB 224 and the charging facility information DB 225.

  In the information processing system 200 according to the first embodiment of the present invention, the charging facility selection device 221 is configured to obtain traffic information and charging facility information from the information providing device 401 outside. It is good also as a structure provided with the information provision means which can perform the same process in the charging facility selection apparatus 221. FIG. In addition, other information providing companies may include companies that provide weather information.

  Internal processing of the vehicle information processing apparatus and the information processing system according to the present embodiment will be described with reference to FIG.

  The ECU 100 starts an internal process for acquiring charging facility information as the charging facility information acquisition unit 212. The ECU 100 acquires the position information a1, the travelable range information a2, the route information a3, and the driving characteristic information a4 of the host vehicle (step S1).

  Note that the ECU 100 does not acquire the route information a3 when the destination is not set. In the case where the charging facility selection device 221 is configured to calculate the travelable range, travelable distance information is acquired instead of the travelable range information a2.

  ECU 100 determines the position of the host vehicle based on information acquired from GPS sensor 110, vehicle speed sensor 111, and gyro sensor 112.

  The ECU 100 executes processing as the travelable distance calculation unit 213. Specifically, the ECU 100 acquires information on the remaining battery capacity from the battery 6 and calculates a travelable distance in the current travel state. Then, ECU 100 applies the calculated travelable distance to the position information of the host vehicle, and determines a travelable range that is a range in which the host vehicle can travel. At this time, the ECU 100 refers to the map information from the map information DB 122.

  The ECU 100 acquires route information indicating a route from the position of the host vehicle to the destination from the acquired position information of the host vehicle. The route information is acquired from the route information indicating the route to the destination selected in advance by the ECU 100 as a route search unit (not shown).

  Here, a route search unit (not shown) will be described. The information processing apparatus 211 according to the first embodiment of the present invention searches for a route from the position of the host vehicle to the destination when the destination is input from the input unit 11 by the driver's operation. It has. ECU100 performs a process as a route search part.

  More specifically, the ECU 100 acquires position information of the host vehicle when a destination is input. Next, the ECU 100 acquires map information from the map information DB 122 and searches for a travel route from the position of the host vehicle to the destination. Then, when the search for the travel route is completed, the ECU 100 superimposes the searched travel route on the map information acquired from the map information DB 122 and displays it on the display unit 10.

  At this time, information related to the charging facility on the travel route can be displayed together. More specifically, the ECU 100 acquires the location information of the charging facility, and executes a process of associating the location information of the charging facility with the travel route. Next, the ECU 100 can display the travel route searched for in the map information and the position information of the charging facility associated with the travel route on the display unit 10. Information regarding the charging facility can be acquired from the charging facility information DB 225 of the charging facility selection device 221. Information associated with the travel route is selected in consideration of the usage scene. Use scenes include, for example, the presence or absence of a passenger detected by the seat sensor of the passenger seat or the seat belt sensor of the passenger seat, the departure time set by the clock function of the ECU 100, the distance to the destination, Judgment is based on the presence or absence of a charging facility.

  The ECU 100 executes processing as the driving characteristic generation unit 214. The ECU 100 analyzes information in the driving action history DB 121 and generates driving characteristic information.

  And the information processing apparatus 211 which concerns on the 1st Embodiment of this invention is the position information a1, the driving | running | working range information a2, route information a3, and the driving characteristic information a4 of the own vehicle with the request | requirement of the information regarding a selected charging facility. , To the charging facility selection device 221 in the center 220.

  More specifically, the ECU 100 executes processing as the charging facility information acquisition unit 212. Specifically, the ECU 100 requests information on the selected charging facility from the charging facility selecting device 221 via the in-vehicle communication unit 9. At this time, the ECU 100 transmits the position information a1, the travelable range information a2, the route information a3, and the driving characteristic information a4 of the host vehicle together with the request.

  Then, the server A that executes processing as the charging facility selection unit 223 requests the information regarding the selected charging facility and the position information a1 of the own vehicle, the travelable range information a2, the route information a3, and the center-side communication unit 222. The driving characteristic information a4 is received.

  Next, the server A determines whether or not the urgent level of charging is high in the host vehicle (step S2). More specifically, the server A executes processing as the charging facility selection unit 223. Server A acquires traffic information and charging facility information from traffic information DB 224 and charging facility information DB 225, respectively.

  The server A determines whether or not the urgent level of charging is high in the host vehicle in consideration of the position information a1, the travelable range information a2 and the route information a3 of the host vehicle.

  The case where “the urgency level of charging is high” means, for example, that when the own vehicle moves according to the route indicated by the route information a3, a certain number of charging facilities are within the driveable range indicated by the driveable range information a2. This is the case when there are fewer or no charging facilities within the range. When there is no charging facility, it is necessary to ignore the route indicated by the route information a3 and go to the charging facility.

  When the server A determines that the urgency level of charging is not high (NO in step S2), the server A determines to use the driving characteristic information a4 as an index when selecting a charging facility (step S3). .

  On the other hand, if the server A determines that the urgency level of charging is high (YES in step S2), the server A does not use the driving characteristic information a4 as an index when selecting a charging facility, but instead uses the driving characteristic information a1 as the position information a1 of the own vehicle. It is determined to use as an index that the distance from the position of the host vehicle shown is close (step S4).

  Next, the server A selects a charging facility based on the “operating characteristic information in step S3” or “being close in step S4” (step S5). More specifically, the server A performs processing as the charging facility selection unit 223. The server A obtains individual position information of a plurality of charging facilities as a charging facility group from the charging facility information DB 225, and uses the vehicle position information a1, the travelable range information a2, and the route information a3 as an index. A charging facility is selected from a plurality of charging facilities based on a certain “operation characteristic information in step S3” or “being close in step S4”.

  Next, the server A acquires the usage status of the charger provided in the charging facility from the charging facility information DB 225 (step S6). More specifically, the server A performs processing as the charging facility selection unit 223. The “charger usage status” includes, for example, the presence or absence of an unused charger, the use end time of a charger that is in use, the charger reservation status, and the like.

  Next, the server A determines whether or not the selected charging facility has room to accept the host vehicle in light of the usage status of the selected charging facility (step S7). More specifically, the server A executes processing as the charging facility selection unit 223. For example, the server A determines whether or not the total time of the time when the host vehicle moves to the selected charging facility and the time when the host vehicle arrives at the selected charging facility until charging is started is within a certain time. . Then, if it is within a certain time, it is determined that there is a margin in the usage status of the charging facility, and if it exceeds a certain time, it is determined that there is no margin in the usage status of the charging facility.

  In making this determination, traffic information, charging facility information, and the like are taken into account, but information such as the remaining battery capacity of the vehicle heading to the periphery of the charging facility can also be taken into account. As a result, it is possible to predict the congestion situation of the future charging facility and select the charging facility, so that it is possible to prevent the vehicle from concentrating on a specific charging facility. As other information, weather information and the like can be taken into account.

  When server A determines that there is room in the usage status of the selected charging facility (YES in step S7), server A transmits information regarding the selected charging facility to information processing apparatus 211 (step S9). More specifically, the server A executes processing as the charging facility selection unit 223. The server A transmits information regarding the selected charging facility to the information processing apparatus 211 via the center side communication unit 222.

  Then, the ECU 100 that executes processing as the charging facility information acquisition unit 212 receives information on the selected charging facility from the charging facility selection device 221 via the in-vehicle communication unit 9. The ECU 100 displays information on the selected charging facility received together with the map information and route information on the display unit 10 and notifies the driver.

  On the other hand, when the server A determines that there is no room for usage of the selected charging facility (NO in step S7), the server A excludes the charging facility determined to have no room for usage from the charging facility group. (Step S8). Then, the server A is again based on the “operation characteristic information in step S3” or “being close in step S4”, which is an index, from the charging facility group excluding the charging facilities having no available usage. The charging facility is selected (step S5).

  Internal processing for storing information related to the timing of charging included in the driving behavior history will be described with reference to FIG.

  When the IG 113 is turned on, the ECU 100 starts an internal process for storing information related to the charging time.

  The ECU 100 acquires the remaining battery capacity when the IG 113 was turned off last time when the IG 113 was turned on (step S11). The remaining battery capacity when the IG 113 was previously turned off is stored in, for example, the backup memory 100d.

  The ECU 100 always stores the SOC in the RAM 100c and manages the remaining battery capacity during traveling. Then, ECU 100 periodically stores the obtained SOC in backup memory 100d.

  The ECU 100 acquires the remaining battery capacity from the battery 6 when the IG 113 is turned on (step S12).

  Next, the ECU 100 compares the remaining battery capacity when the IG 113 was previously turned off with the remaining battery capacity when the IG 113 was turned on to determine whether or not the battery 6 has increased. (Step S13).

  If the ECU 100 determines that the remaining battery capacity has increased (YES in step S12), the ECU 100 stores the remaining battery capacity when the IG 113 was previously turned off as the remaining battery capacity immediately before charging in the driving behavior history DB 121. Accumulate (step S14). The accumulated data further includes a travel distance from the previous charge, position information of the charging facility, and the like. The data is stored in the driving behavior history DB 121. The data stored here is used to calculate a characteristic relating to the timing of charging related to the remaining amount, which is one of the driving characteristics.

  On the other hand, when it is determined that the remaining battery level has not increased (NO in step 13), the ECU 100 ends the process.

  Next, as a second embodiment of the present invention, in the case where the driving characteristic related to the driving characteristic information is a characteristic related to the timing for performing charging with respect to the remaining battery capacity, FIGS. Will be described with reference to FIG. Hereinafter, conventional vehicle information processing apparatuses and information processing systems are referred to as “conventional apparatuses and the like”.

  The first to sixth vehicles shown in FIGS. 5A to 5C will be described. The first to third vehicles are equipped with conventional devices, and the fourth to sixth vehicles are equipped with the devices of the present embodiment.

  The first to sixth vehicles are EV vehicles that are traveling in the same area (for example, within a radius of 3 km). The remaining battery capacities of the first to sixth vehicles are the same. The destinations of the first to sixth vehicles are in the same other area (for example, within a radius of 3 km). The first to sixth vehicles are moving in the direction of the arrow toward the destination. The destination is located ahead of the third charging facility in the traveling direction.

  The charging facility in FIGS. 5A to 5C will be described. When viewed from the current position of the first to sixth vehicles, the first charging facility is relatively close, the second charging facility is relatively intermediate, and the third charging facility is relative At a long distance. The first to third charging facilities are at a sufficiently separated distance.

  The operation of FIG. 5A, which is an example using a conventional apparatus or the like, will be described.

  In the conventional apparatus or the like, in consideration of traffic information and charging facility information, a charging facility that can start charging as quickly as possible is provided, so that the drivers of the first to third vehicles are relatively close to each other. Information on one charging facility is provided. In addition, when the first charging facility (1a) is congested, the conventional device or the like provides information on the other first charging facilities (1b, 1c,...) That are relatively close to each other. . At this time, since the distance between the first charging facility and the second charging facility is sufficiently large, information on the second and third charging facilities is not provided to the first to third vehicles. .

  Therefore, in the conventional apparatus etc., there is a possibility that the charging facility in the same area (area where the first charging facilities 1a, 1b, 1c,...) Are congested may occur.

  The operation of FIG. 5B, which is an example using the apparatus of this embodiment, will be described.

  In the apparatus of this embodiment, the charging facility is selected in consideration of the operation characteristic information. In the second embodiment of the present invention, a characteristic (charging preference) related to the timing of performing charging with respect to the remaining battery capacity is adopted as the driving characteristic. In addition, one or both of traffic information and charging facility information may be considered.

  The driving characteristic generation unit 214 calculates the charging preference mainly based on the history of the remaining battery capacity immediately before charging, which is accumulated in the driving behavior history DB 121. The calculated charging preferences are roughly classified into levels 1 to 3, as shown in FIG.

  Level 1 indicates a preference for charging when the remaining battery capacity is relatively small (less than 0% to 10%). Therefore, level 1 can be said to be a long-distance charging type because the traveling distance between charging and charging is long.

  Level 3 indicates a preference for charging when the remaining battery capacity is relatively large (from 40% to less than 100%). Therefore, level 3 can be said to be a short-distance charging type because the traveling distance between charging and charging is short.

  Level 2 indicates a preference for charging when the battery capacity is relatively between levels 1 and 3 (10% to less than 40%). Therefore, level 2 can be said to be a medium distance charging type.

  The charging preference can be corrected in consideration of other conditions as required, as well as the history of the remaining battery capacity immediately before charging stored in the driving behavior history DB 121. Other conditions include, for example, whether the charging timing differs depending on the destination, the charging timing differs depending on whether a passenger is present or not, or the route to the destination is departed and the destination is not reached Is it a lot?

  Charging timing differs depending on whether the passenger is present or not. For example, when the passenger is present, the charging timing is smaller than when the passenger is absent. This is the case when If you often go out of the way to the destination and go outside the destination, there is a need for battery capacity. is there.

  In the second embodiment of the present invention, the apparatus of the present embodiment is used, the driver of the fourth vehicle is charging preference level 2, the driver of the fifth vehicle is charging preference level 1, and sixth. The driver of the vehicle was determined to have a charge preference level of 3.

  According to the above aspect, in the device or the like according to the present embodiment, the charging facility is selected in consideration of the driving characteristic information that is a feature of the present invention, so that the fourth, fifth, and sixth vehicles can be selected. Thus, it is possible to provide information on the second, third, and first charging facilities in different regions. As a result, it is possible to solve the problem that “charging facilities in the same area are congested” that may occur when a conventional apparatus or the like is used.

  Furthermore, in the case of using a conventional device or the like, information on a charging facility that does not match the driver's preference is provided, but in the case of using the device or the like of the present embodiment, charging that matches the driver's preference Information about facilities can be provided. Thereby, high satisfaction can be obtained from the driver.

  Moreover, although the above example is described as an example in which the apparatus of the present embodiment is used for all of the fourth to sixth vehicles, for example, the present embodiment is implemented only for the fourth or fifth vehicle. Even if a device of the form is used, the fourth vehicle is provided with information on the second charging facility, and the fifth vehicle is provided with information on the third charging facility. The same effects as described above can be obtained.

  A case where the device of this embodiment is used and the urgency of charging is high will be described with reference to FIG.

  FIG. 5C shows a case where the urgent level of charging of the fifth vehicle is high. For example, the fifth vehicle is the first charging facility among the first to third charging facilities because of the remaining battery capacity. This is a case where only one charging facility can be reached.

  As shown in FIG. 5B, when the information facility is selected based on the driving characteristic information by the apparatus of the present embodiment, the fifth vehicle is provided with the information of the third farthest charging facility. The However, the fifth vehicle is provided with the status of the nearest first charging facility because of the remaining battery capacity. Thus, the fifth vehicle can reach the charging facility without using the driving characteristic information as an index and without causing the battery to run out.

  Next, as a third embodiment of the present invention, with reference to FIG. 7A and FIG. 7B, the driving characteristic according to the driving characteristic information is a characteristic of a route traveled in the past. explain.

  The fourth to sixth vehicles shown in FIGS. 7A and 7B will be described. The seventh to ninth vehicles are equipped with conventional devices, and the tenth to twelfth vehicles are equipped with the devices of the present embodiment. The seventh to twelfth vehicles are EV vehicles that are traveling in the same area (for example, within a radius of 3 km).

  The fourth to sixth charging facilities in FIGS. 7A and 7B will be described. The route from the current position of the seventh to twelfth vehicles to the fourth charging facility is a route relatively easy to drive the vehicle, and the route to the sixth charging facility relatively drives the vehicle. It is a difficult route. The feature of the route to the fifth charging facility is configured between the route of the fourth charging facility and the route of the sixth charging facility.

  The operation of FIG. 7A, which is an example using a conventional apparatus or the like, will be described.

  In conventional devices and the like, in general, information related to a charging facility on an easy-to-drive route is preferentially provided, and therefore drivers of the seventh to ninth vehicles are relatively easy to drive the vehicle. Information on the fourth charging facility at is provided. In addition, when the fourth charging facility (4a) is congested, the conventional device or the like has information on the fourth charging facility (4b, 4c...) On the route on which the vehicle is relatively easy to drive. Provided. At this time, since the routes of the fifth and sixth charging facilities are difficult to drive as compared with the route of the fourth charging facility, the seventh and ninth vehicles include the fifth and the fifth charging facilities. Information on 6 charging facilities will not be provided.

  Therefore, in the conventional apparatus etc., there is a problem that the charging facilities (fourth charging facilities 4a, 4b, 4c,...) Matching the route that is prioritized by the unique index of the conventional apparatus etc. are congested. There is a fear.

  The operation of FIG. 7B, which is an example using the apparatus of this embodiment, will be described.

  In the apparatus according to the present embodiment, the charging facility is selected in consideration of the operation characteristic information. In the third embodiment of the present invention, the characteristics of the route traveled in the past (route preference) are adopted as the driving characteristics. In addition, one or both of traffic information and charging facility information may be considered.

  The driving preference generation unit 214 calculates the route preference mainly based on the characteristics of the driving route accumulated in the driving behavior history DB 121. The calculated route preference is roughly classified into levels 1 to 3, as shown in FIG.

  Level 1 shows a preference that does not hesitate even if the route is relatively narrow and the side road is used. Therefore, level 1 is a rough road allowance type that does not require a route that is difficult to drive in order to go to a charging facility that can start charging earlier, for example.

  Level 3 indicates a preference for a route such as a relatively wide road and not using a side road. Therefore, level 3 is a rough road rejection type that avoids a rough road even if the charging start time is slightly delayed, for example.

  Level 2 shows a preference between level 1 and level 3. Therefore, the level 2 is an intermediate type that allows, for example, if the road is a slightly narrow route.

  In the third embodiment of the present invention, the device of the present embodiment is used, the driver of the tenth vehicle has a route preference level of 2, the driver of the eleventh vehicle has a charge preference level of 1, Twelve vehicle drivers were determined to be at charge preference level 3.

  According to the above aspect, in the device or the like according to the present embodiment, the charging facility is selected in consideration of the driving characteristic information that is a feature of the present invention, so that the tenth, eleventh, and twelfth vehicles are selected. Thus, it is possible to provide information on the fifth, sixth, and fourth charging facilities in different regions. As a result, it is possible to solve the problem that “a charging facility that matches a route prioritized by a unique index of the conventional device or the like is congested” that may occur when the conventional device or the like is used.

  Furthermore, in the case of using a conventional device or the like, information on a charging facility that does not match the driver's preference is provided, but in the case of using the device or the like of the present embodiment, charging that matches the driver's preference Information about facilities can be provided. Thereby, high satisfaction can be obtained from the driver.

  Moreover, although the above example is described as an example in which the device of the present embodiment is used for all of the tenth to twelfth vehicles, for example, the present embodiment is implemented only for the tenth or eleventh vehicle. Even if a device of the form is used, the tenth vehicle is provided with information on the fifth charging facility, and the eleventh vehicle is provided with information on the sixth charging facility. The same effects as described above can be obtained.

  As described above, the vehicle information processing apparatus according to the present embodiment can guide the selected charging facility selected from the charging facility group based on the driving characteristics to the driver. More specifically, the vehicle information processing apparatus according to the present embodiment can guide a charging facility different from the conventional one by selecting the charging facility using the driving characteristic as the driver's preference as an index. It becomes.

  Thereby, compared with the past, it can prevent that a vehicle concentrates on a specific charging facility. Moreover, since the charging facility suitable for the driver's preference can be guided, high satisfaction can be brought to the driver.

  In addition to the driving characteristic information, the vehicle information processing apparatus according to the present embodiment is selected based on one or both of information related to the usage status of the charger provided in the charging facility and information related to road traffic. Can provide information on the charging facilities that have been used.
