Thus, a battery charging system is disclosed that eliminates the complexity of the charging operation, prevents forgetting to charge and misses the opportunity of charging, and can always maintain the electric vehicle in a comfortable and usable state. (Patent Document 1).

JP 2006-74868 A

  However, the above battery charging system is a system based on the premise that the number of vehicles and the charging station of the non-contact power feeding method is 1: 1, so when the number of vehicles is larger than the number of charging stations. There was a possibility that the vehicle could not be used due to a shortage of the remaining battery of the vehicle that could not be supported and parked at the charging station.

  The problem to be solved by the present invention is to provide a vehicle management system that suppresses the generation of an unusable vehicle due to a shortage of remaining battery power.

  The present invention provides a charging facility according to the usage time of the vehicle indicated by the reservation information, the power consumption of the battery consumed during the usage time, and the remaining power of the battery while acquiring the reservation information of the vehicle. The remaining power of the vehicle returned to the second parking space is at least the lower limit of the remaining power between the vehicle parked in the first parking space and the second parking space not equipped with the charging facility and the plurality of reservations. The above-described problem is solved by calculating the above combination and assigning the vehicle to the reservation by the calculated combination.

  In the present invention, when the number of charging facilities is smaller than the number of vehicles to be managed, each vehicle is predicted to be charged at the time of return when it is predicted that the remaining battery level may fall below a predetermined lower limit value of the remaining power level. Since the vehicle allocation for the reservation is controlled, after the vehicle is returned, the vehicle that is charged only with an amount of power that cannot be used after that can be recharged at the time of return. Can be avoided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block configuration diagram of a vehicle management system (for example, a car sharing system or a rental car system) according to the present embodiment. FIG. 2 is a block diagram of the management server 100. As shown in FIG. 1, the vehicle management system of this embodiment includes a management server 100, a plurality of shared vehicles 200 used for car sharing, and a plurality of user terminals that can communicate with the management server 100 via the Internet 300. 400 and an administrator terminal 500. In FIG. 1, only two shared vehicles 200 are shown, but the vehicle management system according to the present embodiment includes a large number of shared vehicles 200.

  And in the vehicle management system of this embodiment, many shared vehicles 200 are each parked in the predetermined parking space provided in each place, and the specific many users are parked in the desired parking space. The vehicle 200 can be selected and used.

  As shown in FIG. 3, the vehicle management system of this example also manages the charger 600. FIG. 3 is a conceptual diagram for explaining the common vehicle 200 and the charger 600. The vehicle management system of this example manages the shared vehicle 200, the charger 600, and the parking space at a base that is a return place of the shared vehicle 200. Parking spaces include parking spaces A and B having a charger 600 and a parking space C not having a charger 600. A charger (corresponding to a charging facility) 600 is a non-contact charger using electromagnetic induction, and is embedded in the parking space A and the parking space B, respectively. For example, the charger 600 in the parking space A can be charged only to a vehicle parked in the parking space A. On the other hand, the charger 600 is not embedded in the parking space C, and the shared vehicle 200 parked in the parking space C cannot be charged.

  In the vehicle management system of this example, it is assumed that the number of chargers 600 to be managed is smaller than the number of shared vehicles 200. For example, when providing a car sharing system in an existing parking space, the parking space that can be secured as a return place for the shared vehicle 200 may be limited from the viewpoint of number and location. In addition, when a new charger 600 is set, the number of chargers 600 is smaller than the number of shared vehicles 200 and the number of parking spaces.

  Therefore, as shown in FIG. 3, the number of chargers 600 is smaller than the number of parking spaces A to C. A base where the charger 600 is installed in the main parking spaces A and B but the charger 600 is not installed in the sub parking space C can be a base to be managed by the vehicle management system of this example. . In addition, the parking spaces A and B and the parking space C may be adjacent to each other, or may be arranged at positions separated from each other.

  As shown in FIG. 1, the shared vehicle 200 can communicate with the management server 100 and includes an in-vehicle device 210 and a communication device 220. The common vehicle 200 is an electric vehicle equipped with a battery as a power source. The in-vehicle device 210 transmits information on the use start time and use end time of the shared vehicle 200, information on the travel distance, information on the own vehicle position, vehicle information, information on the remaining amount of battery, etc. from the communication device 220 by wireless communication The data is transmitted to the communication device 120 provided in the management server 100. The communication device 220 receives information transmitted from the management server 100 as a signal.

  In addition, as a method for the in-vehicle device 210 to acquire information on the own vehicle position, for example, a radio wave transmitted from a positioning satellite by a GPS (Global Positioning System) provided in each shared vehicle 200 is received every predetermined time. Thus, a method of acquiring real-time position information of each shared vehicle 200 can be mentioned.

  The user terminal 400 is a terminal owned by a specific number of users who use the vehicle management system of the present embodiment, and can communicate with the communication device 120 provided in the management server 100 via the Internet 300. In the vehicle management system of the present embodiment, each user can operate the user terminal 400 and apply for use of the shared vehicle 200 on the user website.

  Further, in the vehicle management system of the present embodiment, when applying for the use of the shared vehicle 200, the user sets the destination of the shared vehicle 200.

  Examples of the user terminal 400 include various mobile terminals such as a mobile phone and a PDA in addition to a personal computer. When the user terminal 400 is a mobile phone, vehicle information communicated by the communication device 220 is read into the user terminal 400 by wireless communication based on various wireless device standards, and the user terminal 400 receives vehicle information and the like. You may transmit to the management server 100. In FIG. 1, four terminals are illustrated as the user terminal 400, but the number of users using the user terminal 400 and the vehicle management system of the present embodiment is not particularly limited.

  The manager terminal 500 is a manager terminal that manages the vehicle management system of this example, and can communicate with the communication device 120 provided in the management server 100 via the Internet 300. The administrator can check the state of the vehicle, the current position of the vehicle, etc. by operating the administrator terminal 500 and accessing the management website.

  The management server 100 includes a control device 110, a communication device 120, and a database 130.

  The communication device 120 is a device for communicating with the communication device 220 provided in the shared vehicle 200 and the user terminal 400 owned by each user via the Internet 300 by wireless communication. The communication device 120 wirelessly communicates information on the use start time and use end time of the shared vehicle 200, information on the travel distance, information on the vehicle position, and the like from the in-vehicle device 210, and information on the vehicle position from the user terminal 400. The reservation information of the shared vehicle 200 is acquired. The reservation information includes member registration information, desired use start time, scheduled use end time, destination, vehicle information desired to be used, and the like.

  The database 130 is a storage device for storing vehicle information, reservation information, vehicle battery information, and the like. The vehicle information is identification information given to the shared vehicle 200 in advance, the current location of the vehicle, and the like. The reservation information is information such as the vehicle use start date and time, the use end date and time, and the destination. The information on the battery includes information on the remaining amount of power remaining in the battery (hereinafter also referred to as remaining power), and the power consumption of the battery consumed by using the vehicle. Yes. Battery information is recorded for each shared vehicle. When the user of the vehicle management system is limited to members, the database 130 also records registered member information, identification information of the user terminal 400 registered by the member, a password, and the like.

  As shown in FIG. 1, the control device 110 of the management server 100 includes a ROM (Read Only Memory) 112 in which various programs are stored, and a CPU (Central Processing Unit) as an operation circuit for executing the programs stored in the ROM 112. ) 111 and a RAM (Random Access Memory) 113 that functions as an accessible storage device.

  And in order to manage the vehicle management system which concerns on this embodiment, the control apparatus 110, the management function which manages the electric power residual amount of a vehicle, the calculation function which calculates charge time, the function which calculates power consumption, and a vehicle Has a reservation management function for managing reservations. The control device 110 can execute each function by cooperation of software for realizing the above functions and the hardware described above. In addition, as illustrated in FIG. 2, the control device 110 has a remaining power management unit 11, a charging time calculation unit 12, a power consumption calculation unit 13, and reservation management as functional blocks for performing these functions. Part 14.

  Below, each function which the control apparatus 110 of the management server 100 implement | achieves is demonstrated.

  The remaining power management unit 11 uses the communication device 120 to acquire battery information from the shared vehicle 200 and manages the amount of power remaining in the battery (remaining battery power). When the shared vehicle 200 is used, the remaining power management unit 11 communicates with the used vehicle and acquires the remaining power at the start of use. Moreover, when the shared vehicle 200 is returned to the predetermined parking space, the remaining power management unit 11 communicates with the returned vehicle to acquire the remaining power at the time of return. When the battery of the shared vehicle 200 is charged by the charger 600, the remaining power management unit 11 communicates with the vehicle being charged and acquires the current remaining power.

  Identification information is given in advance to the plurality of shared vehicles 200 managed by the system of this example. The remaining power management unit 11, when acquiring battery information through communication with the shared vehicle 200, records the acquired battery information in the database 130 while making the vehicle identification information correspond. Thus, the remaining power management unit 11 manages the past remaining power for each shared vehicle in addition to the remaining power remaining in the battery. Then, the past transition of the remaining power becomes the actual amount of power consumption. For example, by calculating the difference between the remaining power at the start of use and the remaining power at the time of return, the power consumption consumed per use can be calculated as the actual value.

  The charging time calculation unit 12 calculates the charging time of the battery charged by the charger 600 from the remaining power at the start of charging. The charging time calculation unit 12 also calculates a scheduled time for termination of charging by the charger 600.

  The power consumption calculator 13 calculates the power consumption based on the reservation information input from the user. The amount of power consumption is the amount of battery power consumed during the usage time from the start of use to the end of use when the shared vehicle 200 is driven in the usage form indicated by the reservation information. For example, when the destination is input as the reservation information, the power consumption calculation unit 13 calculates a travel route from the current location of the reserved vehicle to the destination, and calculates the power consumption according to the travel route. Calculate.

  When the destination of the reservation information is set to a location other than the vehicle return location, the power consumption calculation unit 13 consumes the vehicle from the current location of the vehicle until it is returned to the current location via the destination. The amount of power is calculated as the amount of power consumed during the reserved usage time.

  When the reservation management unit 14 acquires the reservation information of the new reservation from the communication device 120, the reservation management unit 14 refers to the reservation information recorded in the database 130 and identifies an existing reservation that overlaps with the new reservation. And the reservation management part 14 is parked in the parking space of a base based on the usage time of the vehicle shown by reservation information, the power consumption of the battery consumed during usage time, and the electric power remaining amount of the vehicle at the time of use start. Reservations are allocated to new and existing multiple reservations.

  Here, allocation of a vehicle and a reservation will be described. In the remaining power management unit 11 in FIG. 2, as described above, the power consumption consumed per use is calculated as the actual value. Based on this value, the lower limit value of the remaining amount of battery power that can be considered to be stored in advance as the power consumption corresponding to the travel distance is calculated in average vehicle usage. These are obtained by, for example, a mode value, an average value of power consumption consumed per use, or a value obtained by multiplying these by a coefficient smaller than a predetermined one. If the remaining amount of power of the vehicle battery returned to the parking space C is less than the predetermined lower limit value of the remaining amount of power, when a new reservation is entered, there is sufficient remaining power available for the reservation. There is a high possibility that the vehicle does not store the amount.

Therefore, when a vehicle whose remaining power is less than the predetermined threshold value is returned to the parking space C as described above, the battery cannot be charged and a new reservation may not be assigned to the return vehicle. As a result, the operation rate of the vehicle is lowered. Therefore, the reservation management unit 14 assigns a plurality of vehicles to the plurality of vehicles such that the remaining power of the return vehicle returned to the parking space C that does not have the charger 600 is equal to or greater than a predetermined lower limit value.

  Hereinafter, control of the reservation management unit 14 will be described using a specific example. FIG. 4 is a table showing states of parked vehicles parked in the parking spaces A to C. Parking numbers A to C in FIG. 4 respectively correspond to parking spaces A to C shown in FIG. 3 (the same applies to A, B, and C in FIG. 5 and subsequent figures). The vehicle identification numbers are represented as (1) to (3). At 9:00 today, the remaining battery level of the vehicle (1) (corresponding to the remaining power level) is 100%, the remaining battery level of the vehicle (2) is 80%, and the vehicle (3) is 50%. %. Assume that the vehicles (1) to (3) are returned to the positions of the parking spaces A to C at least before 9:00 today. Since the chargers 600 are provided in the parking spaces A and B, the vehicle (1) and the vehicle (2) are charged, and the remaining battery level is higher than that of the vehicle (3). In addition, the battery remaining amount is represented by a charge state (SOC: State of Charge).

  FIG. 5 is a table for explaining reservation conditions. Reservation I and Reservation II indicate existing reservations, and Reservation III indicates new reservations. For reservation I, the use start time is 9:00, the use end time is 12:00, and the expected power consumption is 10%. For reservation II, the use start time is 9:00, the use end time is 14:00, and the expected power consumption is 30%. For reservation III, the use start time is 9:00, the use end time is 15:00, and the expected power consumption is 45%. Use time is today for all reservations. Note that the predicted power consumption is a value calculated by the power consumption calculation unit 13 and is represented by SOC. The reservation from 9:00 today to 9:00 tomorrow is only reservation (I, II, III).

  When the reservation management unit 14 acquires a new reservation (reservation III), the reservation management unit 14 specifies an existing reservation from the database 130 that overlaps at least a part of the usage time within a predetermined time including the use start time of the new reservation. For example, when the predetermined time is set to 1 hour before and after the use start time of the new reservation, the existing reservation including the time from 8:00 to 10:00 today is specified. In the example, reservation I and reservation II are specified. Thereby, the existing reservation which overlaps with a new reservation can be specified.

  Next, the reservation management part 14 specifies the vehicle which can be utilized by the specified existing reservation (reservation I, II) and the use start time of a new reservation among the vehicles parked in parking space AC. The identified vehicle becomes the vehicle assigned to the reservation. At this time, if the number of specified vehicles is small relative to the number of reservations, a new reservation cannot be accepted, so the reservation management unit 14 determines that the reservation is not possible, and the user who applied for a new reservation Is notified that reservation is not possible.

  The reservation management unit 14 acquires the remaining battery level at the start of use from the remaining power management unit 11 for the specified vehicle. 4 and 5, the vehicles (1) to (3) are identified vehicles, and the reservation management unit 14 determines the remaining battery levels (100%, 80%, 50%) for the vehicles (1) to (3). %). Further, the reservation management unit 14 acquires the predicted power consumption (10%, 30%, 45%) of the reservations I, II, and III from the power consumption amount calculation unit 13.

  The reservation management unit 14 calculates a combination between the identified vehicles (1) to (3) and the reservations I, II, and III. That is, the reservation management unit 14 includes a plurality of reservations (I, II, III) that are parked in the parking spaces A and B with the charger 600 and the parking spaces C without the charger 600, respectively. ) Is calculated. In the example of FIGS. 4 and 5, a combination of 6 patterns is created by the reservation management unit 14.

  Next, the reservation management unit 14 specifies one pattern among the created patterns (combinations), and determines whether or not a predetermined condition regarding the remaining battery level is satisfied. The conditions are determined in order for each pattern.

  There are two conditions regarding the remaining battery level, and the first condition is that the vehicle can arrive at the destination indicated by the reservation information with the remaining battery level at the start of use, and can return to the departure point. The second condition is that the remaining battery level of the return vehicle returned to the parking space without the charger is equal to or greater than a predetermined lower limit value. The predetermined lower limit value is a threshold value of a remaining battery level that can move from a parking space without a charger to a parking space with a charger. As an example, the lower limit is 20%.

  FIG. 6 shows a combination pattern (hereinafter referred to as pattern X) when vehicle (1) is assigned to reservation I, vehicle (2) is assigned to reservation II, and vehicle (3) is assigned to reservation III. I will explain. FIG. 6 is a time chart showing the transition of the remaining battery level of the vehicle.

  At the start of use of reservations (I, II, III), the remaining battery levels of the vehicles (1, 2, 3) are 100%, 80%, and 50%. The expected power consumption of reservations (I, II, III) is 10%, 30%, 45%. In the pattern X, since the remaining battery level at the use start time is larger than the expected power consumption, the reservation management unit 14 determines that the first condition is satisfied by the allocation of the pattern X.

  When each vehicle (1, 2, 3) departs, the reservation I vehicle (1) with the shortest usage time is returned first. Since the parking spaces A to C are vacant, the vehicle (1) is parked in the main parking space A (12:00 today). When the vehicle (1) is returned, the battery consumes the expected power consumption (10%), and the remaining battery level is 90%.

  Next, the vehicle (2) to be returned is parked in an empty parking space B among the main parking spaces (today 14:00). When the vehicle (2) is returned, the remaining battery level is 50%.

  The last returned vehicle (3) is parked in the parking space C because the main parking spaces A and B are full (today 15:00). When the vehicle (3) is returned, the remaining battery level is 5%.

  Since the vehicles (1) and (2) returned to the parking spaces A and B can be charged, the remaining battery level will be 100% by 9:00 tomorrow. On the other hand, for the vehicle (3) returned to the parking space C, the remaining battery level is less than the predetermined lower limit (20%). Furthermore, since the vehicle (3) has been returned to the parking space C without a charger, it cannot be charged, and the remaining battery level will not rise by 9:00 tomorrow. That is, in the pattern X, the remaining battery level of the returned vehicle (3) returned to the parking space without the charger among the returned vehicles becomes less than a predetermined lower limit value. It is determined that the second condition is not satisfied by the assignment.

  If at least one of the first condition and the second condition is not satisfied, the reservation management unit 14 sets the specified pattern as an unsatisfied pattern and excludes it from the combination pattern when the reservation and the vehicle are actually allocated. .

  For the other six patterns, the vehicle (1) is assigned to reservation III, the vehicle (2) is assigned to reservation II, and the vehicle (3) is assigned to reservation I (hereinafter referred to as pattern Y). Will be described with reference to FIG. FIG. 7 is a time chart showing the transition of the remaining battery level of the vehicle.

  In the pattern Y, the remaining battery level at the use start time of each reservation (I, II, III) is larger than the expected power consumption, so the reservation management unit 14 determines that the first condition is satisfied by the pattern Y assignment.

  When each vehicle (1, 2, 3) departs, the reservation I vehicle (3) with the shortest usage time is returned first. Since the parking spaces A to C are vacant, the vehicle (3) parks in the main parking space A (12:00 today). When the vehicle (3) is returned, the battery consumes the expected power consumption (10%) and the remaining battery level is 40%.

  Next, the vehicle (2) to be returned is parked in an empty parking space B among the main parking spaces (today 14:00). When the vehicle (2) is returned, the remaining battery level is 50%.

  The last returned vehicle (3) is parked in the parking space C because the main parking spaces A and B are full (today 15:00). When the vehicle (3) is returned, the remaining battery level is 55%.

  Since the vehicles (2) and (3) returned to the parking spaces A and B can be charged, the remaining battery level will be 100% by 9:00 tomorrow. Since the vehicle (1) returned to the parking space C cannot be charged, the battery remaining amount does not increase from 55% at the time of return, but is not less than a predetermined lower limit value. Therefore, the reservation manager 14 determines that the second condition is satisfied by the pattern Y assignment. In other words, since the pattern Y is a combination in which the remaining battery level of the vehicle returned to the parking space C without the charger is as high as possible, the opportunity for accepting the next reservation increases, Increases the total number that can be accepted.

  When the first condition and the second condition are satisfied, the reservation management unit 14 sets the specified pattern as a formation pattern, and includes it in the list of combination patterns when the reservation and the vehicle are actually allocated.

  The reservation management unit 14 calculates all patterns as described above and lists the established patterns. If there is only one established pattern, the reservation management unit 14 determines a new reservation and assigns the shared vehicle 200 to the reservation according to the established pattern (combination).

  When there are a plurality of established patterns, the reservation management unit 14 calculates the variance of the remaining battery level when each vehicle is returned for each established pattern. Since variance is well known as a statistical calculation method, description thereof is omitted here.

  And the reservation management part 14 selects the formation pattern with the smallest dispersion | distribution from the dispersion | distribution value of each formation pattern, and allocates the shared vehicle 200 to reservation by the selected pattern (combination). When the reservation management unit 14 allocates the reservation and the vehicle, the reservation management unit 14 notifies the user who applied for the new reservation of the reservation confirmation. In addition, the reservation management unit 14 notifies the user of information on the actually allocated vehicle. When the assigned vehicle is changed by applying for a new reservation or canceling an existing reservation, the reservation management unit 14 notifies the user of the changed vehicle information. Thereby, new reservations can be accepted while optimizing the allocation of vehicles including existing reservations.

  On the other hand, if the formation pattern does not exist, the reservation management unit 14 does not accept the new reservation, and notifies the user who applied for the new reservation that the reservation is impossible.

  Next, a control flow of the control device 110 will be described. FIG. 8 is a flowchart for explaining the control flow of the control device 110.

  In step S <b> 1, the reservation management unit 14 of the control device 110 determines whether there is an application for a new reservation from the received data of the communication device 120. When there is an application for a new reservation (there is a new reservation), in step S2, the power consumption amount calculation unit 13 of the control device 110 calculates the power consumption amount based on the reservation information of the new reservation.

  In step S3, the reservation management unit 14 specifies an existing reservation that overlaps at least a part of the usage time indicated by the reservation information of the new reservation. Then, the reservation management unit 14 creates a combination (pattern) of the identified existing reservation and new reservation and the plurality of shared vehicles 200.

  In step S4, the reservation management unit 14 identifies one of the created patterns, assigns a reservation and a vehicle with the specified pattern, and performs a trial calculation to determine whether or not a condition regarding the remaining battery level is satisfied. .

  In step S5, the reservation management unit 14 determines whether or not the vehicle arrives at the destination by comparing the remaining battery level of each vehicle with the power consumption of each reservation. If it does not arrive at the destination, the process proceeds to step S8.

  When arriving at the destination, in step S6, the reservation management unit 14 compares the remaining battery level when the vehicle is returned with a predetermined lower limit value. If the remaining battery level when returning the vehicle is less than the predetermined lower limit value, the process proceeds to step S8.

  When the remaining battery level at the time of returning the vehicle is equal to or greater than a predetermined lower limit value, the reservation management unit 14 determines that the condition regarding the remaining battery level is satisfied, and lists the patterns subjected to the trial calculation as established patterns. (Step S7).

  In step S8, the reservation management unit 14 determines whether there is a pattern that has not been subjected to trial calculation among the patterns calculated in step S3. If there is a pattern for which trial calculation is not performed, the process returns to step S4.

  If trial calculation has been performed for all patterns, in step S9, the reservation management unit 14 determines whether there is a formation pattern. When there is an established pattern, in step S10, the reservation management unit 14 selects a pattern that minimizes the variance of the remaining battery level of the return vehicle from the list patterns. If there is only one established pattern, the flow of step S10 may be omitted.

  In step S11, the reservation management unit 14 assigns a vehicle and a reservation according to the selected pattern. In step S12, the reservation management unit 14 finalizes the new reservation, and the control of this example ends.

  Returning to step S9, if there is no formation pattern, in step S13, the reservation management unit 14 does not accept a new reservation (reservation is not possible), and the control of this example ends.

  As described above, in this example, between the shared vehicle 200 and a plurality of reservations according to the vehicle usage time indicated by the reservation information, the battery power consumption consumed during the usage time, and the remaining battery power consumption. Thus, a combination in which the remaining power of the vehicle returned to the parking space where the charger 600 is not installed is at least the lower limit of the remaining power is calculated, and the shared vehicle 200 is assigned to the reservation by the calculated combination. Thereby, when the number of electric vehicles and the number of infrastructures of a charging facility do not correspond, it can suppress that the vehicle which cannot be used by the shortage of the remaining amount of a battery generate | occur | produces.

  In this example, the charger 600 is a non-contact power feeding method. However, for example, a contact charger that connects the charger and the vehicle with a charging cable may be used.

  The remaining power management unit 11 corresponds to a remaining power management unit according to the present invention, and the reservation management unit 14 corresponds to a reservation management unit according to the present invention.
