Description

  The present invention relates to a management system, a method thereof, and a program for realizing vehicle sharing.

Conventionally, as a solution for reducing traffic congestion and environmental measures, “carpooling” in which a plurality of people ride together in one vehicle is known. Japanese Patent Application Laid-Open No. 2004-228561 describes a technique for determining the compatibility between a carpool recruiter and a carpooler in order to efficiently realize carpooling. Specifically, the criteria for determining the suitability between the carpooler and the carpooler are changed according to the flexibility allowed by the carpooler (for example, even if the carpooler travels for the carpooler) Changing the range to be good, and changing the time zone during which the carpooler may be put on the car of the carpooler).
JP 2003-281238 A

In the conventional technique, when the flexibility is increased, it becomes easier for the carpool recruiter and the carpooler to fit together, so that the carpooling is easily realized. However, increasing the flexibility to make it easier for the carpooler and the carpooler to fit together means that the carpooler will be able to pick up and drop off the carpooler from his / her departure location. The vehicle will travel to a location far away from the route to the destination, and the mileage of the carpooler's vehicle will increase. As a result, for example, when the vehicle of the carpool recruiter is an electric vehicle, if the mileage increases, there is a high possibility that charging is required in the middle of the route, and it is necessary to stop at the charging facility for charging. In the case of a plug-in hybrid vehicle, when the travel distance increases, the amount of fuel consumption increases due to a decrease in the amount of charge of the battery.
The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of carrying out carpooling within the range of stored energy of a battery.

  In order to achieve the above object, in the present invention, the car of the carpooler travels along the route from the carpooler's departure place to the carpooler's destination and destination via the carpooler's place of departure and destination. If the required energy is not exceeded the stored energy of the battery of the carpooler's vehicle, a notification regarding the carpooling is provided to the carpooler and the carpooler. The vehicle in the present invention is assumed to be a vehicle (electric vehicle, plug-in hybrid vehicle, etc.) that can travel using electric power as a power source and has a mechanism for supplying electric power from an external power source. According to the present invention, it is possible to match a carpool solicitor with a carpooler who can perform carpooling within the range of stored energy of the battery of the car of the carpooler.

  A specific configuration for realizing the object of the present invention differs depending on various cases as follows. For example, in the case where the carpool recruiter and the carpooler are in a remote location, each uses a device having a communication function, and exchanges conditions (departure point, destination, etc.) with each other by communication. The equipment used by the carpool recruiter, the equipment used by the carpooler, or the equipment used separately from the equipment, and capable of communicating with the equipment of the recruiter and the equipment of the applicant, The suitability determination between the applicant and the carpool recruiter is performed, and in the case of suitability, the apparatus that has performed the conformity determination notifies the carpooler and the carpool recruiter of information related to the carpool implementation using the communication means. In the case of such a configuration, the carpooler uses a device having a function for accepting input information, a communication function, and a guidance function of the carpooler, for example, a PC, a PDA, a mobile phone, etc. . The carpool recruiter uses devices that also have a reception function, a communication function, and a guidance function. For example, a navigation device provided in a vehicle, a PDA or a mobile phone possessed by the carpool recruiter, and the like are assumed. The

  On the other hand, when the carpooler and the carpooler are in the same place, the carpooler and the carpooler input the respective conditions for a given device, and the suitability determination is performed in the given device, A configuration may be assumed in which notification is made from the predetermined device to the carpooler and the recruiter when the conditions are met. Thus, each means with which the vehicle sharing management system of this invention is provided may be implement | achieved as an independent apparatus, and may be implement | achieved when a some apparatus cooperates by communication.

  Therefore, in the applicant information acquisition means, various configurations as described above can be adopted as long as the departure place and the destination of the rider wishing can be acquired. Also, the recruiter information acquisition means can adopt various configurations as described above as long as the departure place and destination of the carpool recruiter can be obtained. That is, information input directly to a device including these means may be acquired, or information input to a device at a remote location may be acquired through communication. The departure place may be specified by the user inputting an address, a store name, a building name, or the like, or may be specified by information acquired by a GPS receiving unit provided in a device operated by the user.

  The route search means only needs to be able to search for a route from the departure place of the carpooler to the destination of the carpooler via the departure place and destination of the carpooler. Here, it is permitted that the departure place of the rider recruiting person and the departure place of the rider desirer are the same, and that the destination of the rider recruiter and the destination of the rider desirer are the same. In addition, when there are a plurality of carpoolers, some or all of the startpoints and destinations of the carpoolers may be common. For the route search, Dijkstra method, A * algorithm, improved algorithms thereof, or the like can be used.

  In the required energy acquisition means, it is only necessary to acquire the required energy required when the vehicle of the carpool recruiter travels on the aforementioned route, and various configurations can be adopted. For example, for each road section, the energy actually consumed when traveling on the road section in the past is measured and stored as a consumption energy value, and the above-mentioned route is configured by a combination of the plurality of road sections. In this case, the sum of the energy consumption values consumed in the plurality of road sections may be calculated as the energy required for traveling on the route described above. The energy actually consumed may be obtained from the battery consumption in the target road section, or the integrated value of the product of the rotation speed and torque of the transmission shaft that transmits the driving force from the vehicle drive source to the wheels (target You may obtain | require based on the time required for driving | running | working of the road area, and energy transmission efficiency. In addition, for example, based on the driving speed pattern of the driver, the vehicle weight, and other parameters, the force (rolling resistance, air resistance, acceleration resistance, gradient resistance, etc.) that becomes resistance when the vehicle travels is calculated, You may obtain | require based on the integral value of force (integral by distance) and the transmission efficiency of energy.

  The stored energy acquisition means only needs to be able to acquire the stored energy of the battery mounted on the car of the carpooler. The energy stored in the battery or the energy to be stored can be obtained from, for example, an SOC (State Of Charge) representing the charging rate of the battery, the maximum storage capacity of the battery, and the battery voltage.

  In the suitability determination means, it is determined that the carpooler's carpooler's carpooling suits the car if the required energy does not exceed the stored energy. In addition to the above-described conditions, conditions for time described later and conditions for the number of people who can take a ride may be added to the suitability determination. In addition, for example, when selecting a suitable person from among a plurality of carpoolers, a person who presents a starting point or a destination where the required energy in the route derived as a result of the route search is small as carpooler information. May be preferentially selected.

  In the notification means, when it is determined that the carpooling is suitable, it is only necessary to notify the carpooler and the carpooler about the carpooling. Here, the notification regarding the implementation of the carpooling is not limited as long as it is possible to notify that the carpooling can be carried out at least when the conditions of the carpooling applicant and the carpooling recruiter are met. You may make it notify the path | route which drive | works. Furthermore, the scheduled time of arrival at each departure point or destination may be notified, or the number of passengers on the car of the carpooler may be notified.

  Further, in the present invention, the recruiter information obtaining means may obtain the scheduled departure time of the departure place of the carpool recruiter. In this case, the stored energy acquired by the stored energy acquisition means may be energy that is expected to be stored in the battery by the scheduled departure time of the carpool recruiter. In other words, in the car of the carpooler, if the battery is currently being charged or will be charged in the future, the estimated accumulated energy of the battery after charging is obtained based on the battery charging rate at the current time and the future charging time May be. In this way, by having a configuration that uses the stored energy and required energy at a future point in time as comparison targets for suitability determination, it is possible to determine suitability without waiting for the end of charging, and to efficiently operate the carpool management system. be able to.

  Further, in the above configuration, the applicant information acquisition means acquires a desired departure time zone at the departure place of the carpooler, and the route search means includes the car of the carpooler based on the scheduled departure time of the carpooler. The expected arrival time of arrival at the departure place of the applicant may be acquired. In this case, the suitability determination unit may determine that the carpooling is suitable if the expected arrival time is not later than the desired departure time zone. According to this configuration, when the car of the carpooler is scheduled to arrive at the departure place of the carpooler so that it is at least in time for the latest time of the carpooler's desired departure time zone, Can be determined. In addition, when the expected arrival time when the vehicle of the carpooler's vehicle arrives at the departure place of the carpooler is within the desired time zone, it may be determined that the carpooling is suitable.

  The applicant information acquisition means acquires the desired arrival time zone of the carpool applicant's destination, the recruiter information acquisition means acquires the scheduled departure time of the carpool recruiter's departure place, and the route search means Based on the scheduled departure time of the recruiter, the estimated arrival time at which the vehicle for the carpooler arrives at the destination of the carpooler may be obtained. In this case, the conformity determination means arrives at the destination of the carpooler. If the expected arrival time is between the desired arrival time zones, it may be determined that the carpooling is suitable. According to this configuration, it is possible to determine that the conditions for carpooling are suitable when the vehicle for the carpooler is scheduled to arrive during the desired arrival time zone for the carpooler's destination.

  Further, in the present invention, the recruiter information obtaining means may obtain the number of recruitment recruited by the carpool recruiter, and the route search means is the carpooling request that has already been decided to share the car of the carpool recruiter. Search for the route through the starting point and destination of the carpooler who has already decided to ride together and the starting point and destination of the new caring applicant, The suitability determining means may determine that the new carpooler's carpooler's carpooler is compatible when the required energy required for traveling on the route does not exceed the stored energy. According to this configuration, a plurality of riders who wish to ride can be carried on as long as the required energy required for traveling on the route is within the range covered by the stored energy.

  Further, as in the present invention, the vehicle for the carpooler is required to travel on the route from the carpooler's departure place to the carpooler's destination and destination through the carpooler's place of departure and destination. If the energy is acquired and the required energy does not exceed the battery energy stored in the car of the carpooler, the method of notifying the carpooler and carpooler about the carpooling is also applicable as a program or method. is there. The carpool management system, program, and method as described above may be realized as a single device, or may be realized using parts shared with each part of the vehicle, or outside the vehicle or in a remote place. It may be realized in cooperation with existing devices, and includes various aspects. For example, it is possible to provide a navigation device, a method, and a program that include the carpool management system as described above. Further, some changes may be made as appropriate, such as a part of software and a part of hardware. Furthermore, the invention is also established as a recording medium for a program for controlling the carpool management system. Of course, the software recording medium may be a magnetic recording medium, a magneto-optical recording medium, or any recording medium to be developed in the future.

The navigation device 10 includes a control unit 20 including a CPU, a RAM, a ROM, and the like and a storage medium 30, and the control unit 20 can execute a program stored in the storage medium 30 or the ROM. In the present embodiment, as one of the programs, a carpool management program 21 having a function for determining whether or not a carpool recruiter and a carpooler want to join can be executed.

  The carpool management program 21 determines the suitability of the applicant information acquisition unit 21a, the recruiter information acquisition unit 21b, the route search unit 21c, the necessary energy acquisition unit 21d, and the stored energy acquisition unit 21e in order to realize the above-described suitability determination function. 21f and a notification unit 21g, which cooperate with the communication unit 43, the storage medium 30, and the RAM.

The map information 30a includes node data indicating the nodes set on the road, shape interpolation point data for specifying the shape of the road between the nodes, link data indicating the connection between the nodes, and the land existing on the road and its surroundings. It includes data indicating objects and is used for specifying the current position of the vehicle A, searching for a route to the destination, route guidance to the destination, and the like. The link data and node data include information indicating the cost used for route search. The link data includes information such as link distance, average travel time, gradient value, and road surface friction coefficient.

  The vehicle information 30b includes information such as the vehicle type and weight of the vehicle A, the front projection area, and the traveling speed pattern of the carpool recruiter A1. The traveling speed pattern includes, for example, an average vehicle speed, an average acceleration, a deceleration, and the like when the carpool recruiter A1 travels the vehicle A.

  The applicant information acquisition unit 21a is a module that causes the control unit 20 to realize a function of acquiring information indicating conditions of the rider who wants to share the vehicle, such as a departure place and a destination of the rider. Specifically, for example, information indicating the conditions of the carpooler desired input by the carpooler α1 to the terminal α is transmitted to the server 110 by the communication unit 240 and disclosed on the server. When an acquisition request for information on a carpooler is transmitted from the vehicle of the carpooler to the server 110, the server 110 transmits information indicating the conditions of the carpooler to the vehicle A. The control unit 20 acquires information transmitted from the server 110 via the communication unit 43.

  The recruiter information acquisition unit 21b is a module that causes the control unit 20 to realize a function of acquiring information indicating conditions of the rider recruiter, such as the departure place, destination, and scheduled departure time of the rider recruiter. Specifically, for example, the current position of the host vehicle may be acquired based on a signal received by the GPS receiver 40, and the current position may be set as the departure place. Further, the user I / F unit 42 may be operated to acquire the departure place, the destination, and the scheduled departure time set by the carpool recruiter A1. Further, from the battery ECU 41, for example, a time required for fully charging the battery may be acquired, and the scheduled departure time may be acquired based on the time and the current time.

  The route search unit 21c has a function of searching for a route from the departure place of the carpooler to the destination of the carpooler through the departure place and destination of the carpooler in the route search means. This is a module to be realized. For the route search, well-known algorithms such as Dijkstra method, A * algorithm, and improved algorithms thereof can be adopted. The route search unit 21c can calculate the estimated arrival time of the carpooler at the departure place based on the average travel time of the links constituting the route derived as a result of the search. Note that traffic jam information may be received from a road traffic information center (not shown), and a route search taking into account the traffic jam status or calculation of an estimated arrival time may be performed based on the traffic jam information.

  The required energy acquisition unit 21d is a module that causes the control unit 20 to realize a function of acquiring the required energy Ed when the vehicle of the carpool recruiter travels on the route searched by the route search unit 21c. Specifically, for example, based on the driving speed pattern of the driver, the vehicle weight, and other parameters, the force [N] (rolling resistance, air resistance, Acceleration resistance, gradient resistance, etc.) are calculated, and the integral value of the force (integrated with the distance of the target road section) [J (N · m)] is calculated. Further, the energy [J] for the loss specified in advance based on the transmission efficiency of the motor, the transmission efficiency of the transmission shaft mounted on the vehicle, and the like is acquired. Then, the integral value of the force and the energy of the loss are added, and unit conversion is performed to obtain the required energy [kWh]. As the traveling speed pattern, for example, based on the past driving history of the vehicle A by the carpool recruiter A1, average values such as traveling speed, acceleration at the start, and deceleration at the stop are recorded for each road type. . A traveling speed pattern may be individually recorded for a frequently used road, and the data may be used for calculating the required energy. In order to collect these travel speed patterns, the vehicle A is provided with a vehicle speed sensor and an acceleration sensor (not shown). Further, the traveling speed, acceleration, and deceleration used for calculation may be changed in a road section where traffic is congested based on the traffic jam information. The parameters necessary for obtaining the above running resistance (vehicle weight, front projected area, friction coefficient of road surface of target road section, air resistance coefficient, air density, road gradient of target road section, etc.) are as described above. As described above, the vehicle information 30b is stored in advance in the storage medium 30.

  The stored energy acquisition unit 21e is a module that causes the control unit 20 to realize a function of acquiring the stored energy Eb of the battery mounted on the vehicle of the carpooler. Here, the stored energy means the energy stored in the battery or the energy to be stored. The stored energy acquisition unit 21e acquires, for example, an SOC (State Of Charge) [%] indicating the charging rate of the battery, a battery maximum storage capacity [Ah], and a battery voltage [V] from the battery ECU 41, and a multiplication value thereof. As a result, the stored energy [kWh] is acquired.

The suitability determination unit 21f is a module that causes the control unit 20 to realize a function of determining whether or not the carpooling requester's carpooler is compatible with the carpooler. In the present embodiment, when the required energy Ed does not exceed the stored energy Eb, it is determined that it is suitable.
The notification unit 21g is a module that causes the control unit 20 to realize a function of notifying the carpooler and the carpooler about the carpooling when it is determined that the carpooling is suitable. Here, the notification regarding the implementation of the carpooling is not limited as long as it is possible to notify that the carpooling can be carried out at least when the conditions of the carpooling applicant and the carpooling recruiter are met. You may make it notify the path | route which drive | works. Furthermore, the scheduled time of arrival at each departure point or destination may be notified.

(1-2) Carpool management processing:
Next, the carpool management process in the above configuration will be described in detail. FIG. 2 is a flowchart showing the carpool management process executed on the navigation device 10 side. First, the control unit 20 acquires carpool recruiter information by the process of the solicitor information acquisition unit 21b, and transmits the acquired information to the server 110 (step S100). In the present embodiment, the scheduled departure time, departure place, and destination of the carpool recruiter are acquired and transmitted to the server 110 via the communication unit 43. The server 110 receives this information and publishes it on the server.

  Next, the control unit 20 acquires the stored energy Eb of the battery by the process of the stored energy acquisition unit 21e (step S105). Specifically, when the battery is being charged or is scheduled to be charged, the control unit 20 determines the charge rate of the battery after the end of charge based on the charge rate SOC [%] of the battery at the current time and the future charge time. The SOC [%] is acquired from the battery ECU 41. The accumulated energy of the battery in the fully charged state can be obtained as a product of the maximum storage capacity [Ah] of the battery and the voltage [V] during full charging. Accordingly, the stored energy [kWh] of the battery after the end of charging can be obtained by multiplying the stored energy of the battery in the fully charged state by the charge rate SOC [%] after the end of charging. As described above, when the battery is being charged or is scheduled to be charged in the future, the stored energy at the end of charging, which is a future time, can be acquired. As a result, in the processing of the later-described conformity determination unit 21f It is possible to compare the stored energy and the required energy at a future time. That is, it is possible to perform the conformity determination without waiting for the end of charging, so that the carpool management system can be efficiently operated. Of course, when the battery is not being charged or when it is not scheduled to be charged before the scheduled departure time, the stored energy is acquired based on the current charging rate SOC [%].

  Next, the control part 20 acquires carpooler information by the process of the applicant information acquisition part 21a (step S110). Specifically, the control unit 20 acquires the departure place and the destination of the carpooler. These carpooler information is input to the terminal α by the operator of the terminal α (carpooler), then transmitted to the server 110 by the process of the carpooler terminal program 221, and transmitted from the server 110 to the vehicle A. Information.

  Next, the control unit 20 searches for a route by the processing of the route search unit 21c, and acquires route information indicating the searched route (step S115). Specifically, a route from the departure place of the carpool recruiter to the destination of the carpool seeker via the departure place and destination of the carpooler is searched, and route information indicating the route is acquired. Here, the departure place of the carpool recruiter and the departure place of the carpooler may be common, or the destination of the carpooler and the destination of the carpooler may be common.

  Next, the control unit 20 acquires the required energy Ed required for traveling on the route by the processing of the required energy acquisition unit 21d (step S120). Specifically, for example, as described above, based on the driving speed pattern of the driver, the vehicle weight, and other parameters, the force (rolling resistance, air resistance, acceleration resistance, gradient) that becomes resistance when the vehicle travels Resistance, etc.) is calculated, and the required energy Ed is obtained as an integral value of the force.

  Next, the control unit 20 determines whether or not the stored energy Eb exceeds the required energy Ed by the processing of the conformity determining unit 21f (step S125), and when the stored energy Eb is determined to exceed the required energy Ed. Then, the control unit 20 calculates the estimated arrival time when the vehicle of the carpool recruiter arrives at the departure place of the carpooler by the process of the route search unit 21c (step S130). Subsequently, the control unit 20 notifies the server 110 that the carpooling can be performed because the carpooling conditions are met by the processing of the notifying unit 21g (step S135). At this time, the server 110 is notified together with the estimated arrival time at the departure place of the carpooler calculated in step S130. When it is not determined in step S125 that the stored energy Eb exceeds the required energy Ed, the control unit 20 notifies the server 110 that the carpooling cannot be performed by the processing of the notification unit 21g (step S140).

  Next, processing executed at the terminal α of the carpooler will be described. FIG. 3 is a flowchart of the carpool management process of the carpooler terminal program 221 executed by the control unit 220 of the terminal α. First, the control unit 20 acquires carpooler information and transmits it to the server 110 (step S200). The information transmitted here is disclosed on the server, and is received by the vehicle A in the above-described step S110, and the route search and the comparison between the stored energy Eb and the necessary energy Ed are performed. And the control part 220 receives the information regarding implementation (or non-implementation) of the carpooling transmitted from the vehicle in the above-described step S135 or S140 from the server 110 (step S205).

  As described above, according to the present embodiment, it is possible to match a carpool recruiter and a carpooler who can carry out carpool within the range of the stored energy of the battery of the car of the carpool recruiter.

The selection criteria for the carpooler are, for example, as follows. First, a route from the departure place of the carpool recruiter to the destination is searched based on the departure place and destination of the carpool recruiter and the scheduled departure time, and the estimated arrival time of the carpool recruiter's destination is acquired. And, if you are a carpooler who includes your desired departure time zone between the scheduled departure time and the expected arrival time, the time zone closest to the scheduled departure time of the rider recruiter will be your desired departure time The carpooler specified as the belt is preferentially selected.

The functions of these parts are the same as the functions of the corresponding parts in the carpool management program 21 of the first embodiment. The storage medium 130 stores map information 130c and energy information 130d. The map information 130c may have the same configuration as the map information 30a described above. The energy information 130d includes a value indicating the energy required for travel of the link in association with the link included in the map information 130c. In addition, the value of the required energy matched with the link is prepared in advance for a plurality of types, for example, for each vehicle type, and stored as energy information 130d.

  FIG. 5 is a flowchart showing the carpool management process according to the second embodiment. A duplicate description of processing common to the first embodiment is omitted. First, the control unit 120 acquires carpool recruiter information and stored energy from the vehicle through the processing of the recruiter information acquisition unit 121b and the stored energy acquisition unit 121e (step S300). Specifically, together with the identification information of the carpool recruiter (vehicles), the departure place and destination of the carpool recruiter, the scheduled departure time of the carpool recruiter's departure place, vehicle information, the number of carpool recruiters, and the stored battery energy Information such as Eb is acquired from the vehicle. The accumulated energy Eb indicates the accumulated energy after the end of charging when charging or is scheduled to be charged before the scheduled departure time, and indicates the accumulated energy at that time in other cases. When there is information on a plurality of rider recruiters, these pieces of information are acquired from the vehicles of each rider recruiter. Note that the number of people who can share a car may be acquired according to the vehicle type of the car of the carpooler, unless otherwise specified by the carpooler.

  In the carpool management process of this embodiment, the processes from step S305 to S360 are repeatedly executed for the number of carpool recruiters. The control unit 20 acquires carpooler information by the processing of the applicant information acquisition unit 121a (step S305). Specifically, together with the identification information of the carpooler's (terminal), information such as the departure place and destination of the carpooler and the desired departure time zone at the carpooler's departure location is acquired from the terminal. If there are multiple carpoolers, these pieces of information are acquired from the terminals of each carpooler.

  Next, the processing from step S310 to S345 is repeatedly executed for the number of people who wish to ride together. The control unit 120 searches for a route from the carpooler's departure location to the carpooler's destination and destination via the route searcher 121c processing (step S310). . The route searched here is the carpool that has already been determined from the departure place of the carpool recruiter if the execution of the process of step S310 is the second or later and at least one carpooler has already been determined. This is a route that leads to the destination of the rider recruitment person via the departure place and destination of the applicant and the departure place and destination of the carpooler newly selected as the determination target. In addition, a part or all of the starting point and destination of each carpooler may be common.

  Next, the control unit 120 calculates the required energy Ed necessary for traveling on the route searched in step S310 by the process of the required energy acquisition unit 121d (step S315). Specifically, if information indicating the vehicle type is included as vehicle information in step S300, the energy information 130d is referred to, and the required energy value associated with the link constituting the route corresponds to the vehicle type. The necessary energy Ed required for traveling on the route is calculated by sequentially obtaining values to be added and adding them.

  Next, the control unit 120 determines whether or not the stored energy Eb exceeds the required energy Ed by the processing of the conformity determination unit 121f (step S320). By the process of 121f, it is determined whether or not the car of the carpooler can arrive at the departure place of the carpooler during the desired time of departure of the carpooler (step S325). Specifically, by the process of the route search unit 121c, the estimated arrival time at which the car of the carpooler arrives at the departure place of the carpooler is obtained based on the scheduled departure time of the carpooler, and the estimated arrival time is It is determined whether or not it is within the desired departure time of the carpooler. If the execution of step S325 is performed for the second time or later and at least one carpooler has already been determined, the carpooler who has already been determined, and this time, a new determination target is selected. It is determined whether or not the carpooler can arrive within each desired departure time for all the carpoolers. In addition, when the vehicle of the carpool recruiter is being charged or is scheduled to be charged before the scheduled departure time, the stored energy varies according to the charging time, and as a result, the travelable distance also varies. Therefore, the carpooler who is determined to be suitable may differ depending on the charging time, and the number of people who can ride the car may vary.

  In step S325, when it is determined that the vehicle of the determination target carpool recruiter who is the target of the conformity determination can arrive within the desired departure time zone, the control unit 20 recruits the determination target carpooler as the determination target carpool recruitment. The vehicle is determined to be suitable for sharing the vehicle with the vehicle, and the number of passengers sharing the determination target vehicle sharing recruiter is incremented (step S330). If it is not determined in step S320 that the stored energy Eb exceeds the required energy Ed, or if it is not determined in step S325 that the vehicle can arrive within the desired departure time zone, the control unit 20 will request the determination target carpooler. Determines that it is incompatible with the determination target carpool recruiter (step S335).

  Next, the control unit 20 determines whether or not the determined number of passengers is greater than or equal to the recruitment number by the processing of the suitability determination unit 121f (step S340). If it is less than the recruitment number, the control unit 120 determines whether or not there is a carpooler who has not yet performed the suitability determination (step S345). If it is determined that there is a carpooler, step S310 to step S345 are performed. Repeat the process. That is, when the number of carpoolers who have already decided to ride in the car of the carpooler's vehicle is less than the number of carpoolers, the new carpooler is selected as a target for suitability determination. If it is determined in step S340 that the recruitment number has been reached, or if it is not determined in step S345 that there is a non-conformity determination carpooler, the control unit 120 is determined to be suitable by the processing of the conformity determination unit 121f. The carpooler is confirmed as a passenger to this vehicle (step S350). As described above, in the present embodiment, the required energy of the route passing through the starting point and the destination of each carpooler is within a range that does not exceed the stored energy, and each carpooler is within the recruitment number. If the vehicle of the carpooler can arrive at the departure place within the desired departure time zone, a plurality of carpoolers can be shared.

  Next, by the processing of the notification unit 121g, the control unit 20 notifies the determination target carpool recruiter and the rider who has decided to share the vehicle of the determination target carpool recruitment about the carpooling execution. (Step S355). Specifically, the confirmed carpooler is notified of the fact that the carpool has been confirmed and the estimated arrival time at which the car of the carpooler will arrive at the departure place of the carpooler. For carpoolers, information indicating the route of the carpooler's departure point and destination, the number of passengers traveling on the carpooler's vehicle, and the expected arrival of each carpooler's departure point and destination Notify time etc.

Next, the control unit 20 determines whether or not there is a carpool recruiter for which the conformity determination has not yet been performed (step S360). If it is determined that there is a carpool recruiter, the processing from step S305 to step S360 is repeated. Execute. If it is not determined in step S360 that there is a non-conformity-determined carpool recruiter, the carpool management process ends.
As described above, in the present embodiment, it is possible to match a carpool recruiter with a plurality of carpoolers who can share a car within the range of stored energy of the battery of the car of the carpool recruiter.

(3) Other embodiments:
The above embodiment is an example for carrying out the present invention. The route from the departure place of the rider recruiter to the destination of the rider seeker via the departure place and destination of the rider wanter As long as the required energy for the vehicle of the vehicle is acquired and the required energy does not exceed the accumulated energy of the battery of the carpooler's vehicle, as long as the carpooler and the carpooler are notified about the carpooling, Various other embodiments can be employed.

  A specific configuration for realizing the object of the present invention differs depending on various cases as follows. For example, in the case where the carpool recruiter and the carpooler are remote from each other as in the above embodiment, each uses a device having a communication function, and the conditions (departure point, destination, etc.) are determined by communication. Communicate. The equipment used by the carpool recruiter, the equipment used by the carpooler, or the equipment used separately from the equipment, and capable of communicating with the equipment of the recruiter and the equipment of the applicant, It is assumed that the conformity determination between the applicant and the carpool recruiter is performed, and if it matches, the device that performed the conformity determination notifies the carpooler and the carpool recruiter of information related to the carpool implementation using communication means. Is done. In the above embodiment, an example in which the device used by the carpool recruiter is a navigation device, but it may be a PDA or a mobile phone having a communication function.

  On the other hand, when the carpooler and the carpooler are in the same place, the carpooler and the carpooler input the respective conditions for a given device, and the suitability determination is performed in the given device, A configuration may be assumed in which notification is given from the predetermined device to the carpooler and the recruiter when the conditions are met. Thus, each means with which the vehicle sharing management system of this invention is provided may be implement | achieved as an independent apparatus, and may be implement | achieved when a some apparatus cooperates by communication.

  Furthermore, the necessary energy acquisition means only needs to acquire the necessary energy required when the car of the carpooler travels along the route, and a method other than the method described in the above embodiment may be employed. For example, for each road section, when the energy actually consumed when traveling on the road section in the past is measured and stored as data, and the above-mentioned route is composed of a combination of the plurality of road sections May calculate the sum of the energy consumed in the plurality of road sections as the energy required for traveling on the above-described route. The actual consumed energy may be obtained from the battery consumption in the target road section, or the product [W] of the rotational speed and torque of the transmission shaft that transmits the driving force from the driving source of the vehicle to the wheels. You may obtain | require based on an integral value (integral in the time required for driving | running | working of the object road area), and energy transmission efficiency.

  In addition, in the suitability determination means, it is determined that the carpooler's carpooler's carpooling suits if the required energy does not exceed the stored energy, but the carpooling applicant's carpooler is determined to be compatible. In addition to the above conditions, conditions related to time as described in the above embodiment (the vehicle arrival time of the carpooler's vehicle is within the desired departure time zone of the carpooler), and conditions regarding the number of carpoolers seeking recruitment (Determine that it is suitable if it is within the recruitment number) may be added. In addition, for example, if the expected arrival time of the carpooler's departure place is not later than the desired timetable of departure of the carpooler, the carpool may be determined to be suitable. According to this configuration, when the car of the carpooler is scheduled to arrive at the departure place of the carpooler so that it is at least in time for the latest time of the carpooler's desired departure time zone, Can be determined.

  The applicant information acquisition means acquires the desired arrival time zone of the carpool applicant's destination, the recruiter information acquisition means acquires the scheduled departure time of the carpool recruiter's departure place, and the route search means Based on the scheduled departure time of the recruiter, the estimated arrival time at which the vehicle for the carpooler arrives at the destination of the carpooler may be obtained. In this case, the conformity determination means arrives at the destination of the carpooler. If the expected arrival time is between the desired arrival time zones, it may be determined that the carpooling is suitable. According to this configuration, when the car of the carpooler is scheduled to arrive at the carpooler's destination during the desired time of arrival at the carpooler's destination, it can be determined that the carpooling conditions are met. it can.

  In addition, in the conformity determination means, for example, when selecting a suitable person from among a plurality of carpoolers, the starting point or destination where the required energy in the route derived as a result of the route search is small is used as the carpooler information. The presenting applicant may be preferentially selected.

  There may be a plurality of destinations of the carpooler who are acquired by the applicant information acquisition means. That is, in addition to the departure place and the first desired destination of the carpooler, for example, a second desired destination closer to the departure place on the route than the first desired destination may be acquired. The second desired destination is, for example, another transportation platform (a public transportation platform such as a taxi or the like, a charging facility where other passenger recruiting vehicles can gather) that can reach the first desired destination. In this case, in the conformity determination means, the necessary energy required for the route from the carpooler's departure location to the carpooler's departure location and the first desired destination, If it exceeds, the required energy for the next route may be calculated. That is, the energy required for the route from the departure place of the carpooler to the destination of the carpooler via the departure place and the second desired destination of the carpooler. If the required energy of the latter is less than the stored energy, both may be notified that the carpooler can share the car with the carpooler between the starting point of the carpooler and the second desired destination.
