Description

  The present invention relates to a shared system for a plurality of electric vehicles that run using electric power charged in a battery.

  A so-called car sharing system in which one or a plurality of automobiles are shared by a plurality of users is known. Since the maintenance cost of automobiles can be suppressed, the number of users using a car sharing system has been increasing in recent years.

  In addition, efforts to revitalize cities using the car sharing system are being experimentally promoted in some cities. In this approach, parking lots are provided in close proximity to each of a plurality of commercial facilities scattered in a city. A consumer, who is a user, rents a car parked in a certain parking lot and drives to another parking lot by driving himself. Then, the user discards the car that has been driven to the other parking lot and uses a nearby commercial facility. The discarded car is rented to another user at the other parking lot. In this way, efforts are being made to revitalize cities by allowing consumers to flow between multiple commercial facilities using a car sharing system.

  Furthermore, due to growing environmental awareness, in car sharing systems, the replacement of automobiles that run on fossil fuels such as gasoline with electric cars that run on electric power charged in batteries is proceeding (see the following patents). Reference 1). In the above-mentioned efforts to revitalize cities using the car sharing system, chargers are installed in each parking lot. The electric vehicle abandoned at each parking lot is connected to the charger, and the battery is charged while waiting for the next user.

Japanese Patent Laid-Open No. 11-313403

  Although the time required for charging the battery of the electric vehicle has been greatly shortened by recent technological advances, the time required for refueling the gasoline vehicle is still longer. For this reason, even if the electric vehicle abandoned in each parking lot is connected to the charger, it will take a long time before it can be used by the next user.

  Therefore, in some parking lots, there are a large number of electric vehicles that have a sufficient amount of power remaining in the battery and are readily available, while in other parking lots, the electric vehicles are readily available. There has been a problem that the operating rate of a plurality of electric vehicles is low, such as lack of electricity.

  This invention is made | formed in view of such a subject, The objective is to provide the electric vehicle common use system which can improve the operation rate of several electric vehicles.

In order to solve the above-mentioned problem, an electric vehicle shared system according to the present invention is a shared system (10) for a plurality of electric vehicles (EV) that travels using electric power charged in a battery (111), and the battery An information acquisition means (22) for acquiring information relating to a parking lot selected by a user as a departure place and a destination from a plurality of parking lots (P1, P2, P3) having a charger (CG) for charging the A remaining amount detecting means (112) for detecting the remaining amount of electric power of the battery of the electric vehicle, a vehicle selecting means (23) for selecting one electric vehicle from among the electric vehicles parked at the departure place, a vehicle Vehicle provision means (24) for providing the user with the electric vehicle selected by the selection means. The vehicle selection means calculates the electric power required for traveling from the departure place to the destination based on the distance traveled from the departure place to the destination, and the remaining amount of electric vehicle battery power is determined from the departure place to the destination. Based on whether or not the electric power required for traveling to the ground is greater than or equal to the electric power necessary for traveling from the departure place to the destination, it is determined whether or not the battery is charged and the vehicle is parked at the departure place. From the electric vehicle, a plurality of available vehicles, which are electric vehicles in which the battery is charged with the electric power necessary for traveling from the starting point to the destination, are extracted, and the electric vehicle battery parked at the destination is extracted. When the remaining amount of power is equal to or greater than the predetermined amount, one available vehicle having a minimum remaining battery power compared to other available vehicles is selected from among a plurality of available vehicles.

According to the present invention, when an electric vehicle having a remaining amount of battery power equal to or larger than a predetermined amount is parked in a parking lot as a destination, the vehicle can be provided in a parking lot as a departure location. From the other vehicles that can be provided, a single vehicle that has a minimum remaining battery power is selected and provided to the user. Here, the vehicle that can be provided refers to an electric vehicle in which the battery is charged with electric power necessary for traveling from the departure place to the destination. When the user drives the electric vehicle to the destination and disembarks at the destination, the parking lot that is the destination has an electric vehicle with a large remaining amount of battery power and a remaining amount of battery power. A small quantity of electric vehicles will be deployed. For this reason, it becomes possible to prevent the electric vehicle having a large amount of battery power remaining from being biased to a specific parking lot.

The vehicle control unit 190 is a computer system that transmits and controls a control signal to each functional unit and obtains information from each functional unit to monitor an operation state.

  Next, the flow of processing in the electric vehicle shared system 10 will be described with reference to FIGS. 3 to 5.

  FIG. 3 shows a vehicle selection unit of the vehicle management server 20 triggered by the user U who desires to use the vehicle EV inputting predetermined information at the communication terminal 30 and receiving the information at the vehicle management server 20. 23 is a routine to be executed. In the following, for the sake of simplicity, a detailed description will be given assuming that the vehicle management server 20 collectively performs processing performed by each part such as the vehicle selection unit 23 of the vehicle management server 20.

  First, in step S101, the vehicle management server 20 calculates a travel distance from the parking lot that is the departure place input by the user U to the parking lot that is the destination. Hereinafter, the case where the user U selects the first parking lot P1 as the departure point and the second parking lot P2 as the destination will be described as an example. The vehicle management server 20 starts from the first parking lot P1 to the second parking lot. The travel distance of a general route to the parking lot P2 is calculated.

  Next, in step S102, the vehicle management server 20 calculates the remaining battery level required for the vehicle EV to travel the travel distance calculated in step S101.

  Next, the vehicle management server 20 determines whether or not a vehicle that can be lent to the user U (a vehicle that can be provided) is parked at the departure place in step S103. Specifically, it is determined whether or not a vehicle EV having a battery level equal to or higher than the required battery level calculated in step S102 is parked in the first parking lot P1 that is the departure point. When the corresponding vehicle EV is not parked in the first parking lot P1 (S103: NO), the vehicle management server 20 proceeds to step S110.

  Next, the vehicle management server 20 transmits information indicating that the vehicle EV cannot be lent to the communication terminal 30 in step S110. In the communication terminal 30 of the user U who has received the information, that effect is displayed on the display unit 33. The user U can confirm that the vehicle EV cannot be used by the display content of the display unit 33.

  On the other hand, when it is determined in step S103 that the vehicle EV having a battery remaining amount equal to or greater than the necessary battery remaining amount calculated in step S102 is parked in the first parking lot P1 that is the departure place (S103: YES). The vehicle management server 20 proceeds to step S104.

  Next, the vehicle management server 20 extracts a plurality of vehicles that can be rented to the user U from the vehicles EV parked in the first parking lot P1 in step S104. That is, a plurality of vehicles EV having a remaining battery level equal to or greater than the required remaining battery level calculated in step S102 are extracted.

  Next, in step S105, the vehicle management server 20 determines whether or not a predetermined number or more of vehicles EV having a remaining amount of battery in the second parking lot P2 that is the destination are parked. The predetermined amount is set to an amount of electric power necessary for the vehicle EV to travel from the second parking lot P2 to the first parking lot P1 or the third parking lot. When a predetermined number or more of vehicles EV having a battery remaining amount equal to or greater than a predetermined amount are parked in the second parking lot P2 (S105: YES), the vehicle management server 20 proceeds to step S106.

  Next, in step S106, the vehicle management server 20 determines whether or not the number of vehicles EV parked in the second parking lot P2 that is the destination is a predetermined number or more. The predetermined number is set to a necessary and sufficient number so that the vehicle EV that can be lent to the user U at the second parking lot P2 is not lost based on the past use record of the vehicle EV. When the number of vehicles EV parked in the second parking lot P2 is equal to or greater than the predetermined number (S107: YES), the vehicle management server 20 proceeds to step S107.

  Next, in step S107, the vehicle management server 20 selects a vehicle EV with the smallest remaining battery capacity from the plurality of vehicles EV extracted in step S104.

  Next, the vehicle management server 20 transmits the ID number 41 of the IC card 40 of the user U desiring to use to the selected vehicle EV in step S108. The vehicle EV that has received the ID number 41 waits for the user U to use it.

  Next, in step S109, the vehicle management server 20 transmits information on the selected vehicle EV to the communication terminal 30 of the user U who wants to use the vehicle EV, and lends the vehicle EV. In the communication terminal 30 of the user U who has received the information, information on the vehicle EV to be rented is displayed on the display unit 33. The user U can check the vehicle EV used by the user U based on the display content of the display unit 33.

  As described above, the vehicle management server 20 is in the case where a predetermined number or more of vehicles EV having a battery remaining amount of a predetermined amount or more are parked in the second parking lot P2 that is the destination (S105: YES). When the number of vehicles EV parked in the second parking lot P2 is equal to or greater than a predetermined number (S106: YES), the remaining battery level is the smallest among the plurality of extracted rentable vehicles. A vehicle is selected and lent to the user U. This is because even when another user U desires to use the vehicle EV from the second parking lot P2, the second parking lot P2 can travel to the first parking lot P1 or the third parking lot P3. Since the vehicle EV is sufficiently deployed, there is a risk that the vehicle EV that can be rented to the user U will be insufficient in the second parking lot P2 even if the vehicle EV with the minimum remaining battery level is moved from the first parking lot P1. Because there are few.

  On the other hand, when it is determined in step S105 that a predetermined number of vehicles EV having a battery remaining amount equal to or larger than a predetermined amount are not parked in the second parking lot P2 that is the destination (S105: NO), the vehicle management server 20 Advances to step S111.

  Moreover, also when it determines with the number of vehicles EV parked in the 2nd parking lot P2 which is a destination being less than predetermined number by step S106 (S106: NO), the vehicle management server 20 is step S111. Proceed to

  In step S111, the vehicle management server 20 selects a vehicle EV having the maximum remaining battery capacity from the extracted plurality of rentable vehicles. Thereafter, as described above, the vehicle management server 20 transmits the ID number 41 to the selected vehicle EV in step S108, and further transmits information on the selected vehicle EV to the communication terminal 30 of the user U in step S109. Then, the vehicle EV is rented out.

  As described above, when the vehicle management server 20 does not park a predetermined number of vehicles EV having a battery remaining amount equal to or greater than a predetermined amount in the second parking lot P2 that is the destination (S105: NO), If the number of vehicles EV parked in the second parking lot P2 is less than the predetermined number (S106: NO), the vehicle with the maximum remaining battery power is selected from the extracted plurality of rentable vehicles EV Then lend it to the user U. This is a vehicle that can travel to the first parking lot P1 or the third parking lot P3 in the second parking lot P2 when another user U desires to use the vehicle EV from the second parking lot P2. This is because the EV is not sufficiently deployed, and it is necessary to move the vehicle having the largest remaining battery amount from the first parking lot P1 and to deploy a vehicle that can be rented to the user U to the second parking lot P2.

  In addition, when the number of vehicles EV parked at the second parking lot P2 that is the destination is small at the time of departure of the user U, when the user U arrives at the second parking lot P2, the second parking lot The next user U starting from P2 can use the vehicle EV. Further, when the number of vehicles EV parked in the second parking lot P2 that is the destination is large at the time of departure of the user U, when the user U arrives at the second parking lot P2, the second is first. There is a possibility that some of the vehicles EV parked in the parking lot P2 are charged to some extent. For this reason, the next user U from the second parking lot P2 can use a vehicle other than the vehicle EV used by the previous user U. Therefore, it is useless to lend a vehicle EV having a large remaining battery level to the previous user U.

  FIG. 4 is a routine executed by the vehicle control unit 190 of the parked vehicle EV when the user U starts using the vehicle EV at the first parking lot P1, which is the departure place. The vehicle control unit 190 starts execution of this routine, triggered by the use date and time of the vehicle EV reserved by the user U.

  In step S201, the vehicle control unit 190 determines whether or not the IC card reader 172 of the user U who has reserved the use of the vehicle EV has been detected by the IC card reader 172. Specifically, it is determined whether or not the ID number 41 of the IC card 40 held over the IC card reader 172 matches that of the user U's IC card 40 that has reserved use of the vehicle EV. Even when the IC card 40 is not immediately detected when the usage date and time reserved by the user U is reached (S201: NO), the vehicle control unit 190 waits until a predetermined time elapses as shown in step S207 (S207: NO). If the IC card reader 172 has read the ID number 41 of the IC card 40 of the user U who has reserved use of the vehicle EV before the predetermined time elapses (S201: YES), the vehicle control unit 190 proceeds to step S202. Proceed to

  Next, in step S202, the vehicle control unit 190 operates the door lock unit 140 to unlock the door lock. Thereby, the door of the vehicle EV that has been locked until then can be opened and closed, and the user U can get into the vehicle EV.

  Next, the vehicle control unit 190 waits for insertion of the IC card 40 into the IC card slot 171 in step S203. As described above, the IC card slot 171 is provided in the passenger compartment of the vehicle EV. When the user U who has boarded the vehicle EV inserts his own IC card 40 into the IC card slot 171, the vehicle control unit 190 proceeds to step S204.

  Next, the vehicle control unit 190 operates the ignition switch unit 150 in step S204. Thereby, the user U can turn on the ignition switch 151 which has been in the off state. When the ignition switch 151 is turned on, electric power can be supplied from the battery 111 of the vehicle EV to the electric motor, and the vehicle EV can run.

  Next, in step S205, the vehicle control unit 190 determines whether or not the position where the shift lever 161 of the vehicle EV is disposed is other than “P” (parking: parking). That is, it is determined whether or not the user U is operating the shift lever 161 to start traveling of the vehicle EV. When it is determined that the position at which the shift lever 161 is disposed is other than “P” (S205: YES), the vehicle control unit 190 proceeds to step S206.

  On the other hand, when it is determined in step S205 that the shift lever 161 is disposed at “P” (S205: NO), the vehicle control unit 190 proceeds to step S208.

  Next, the vehicle control unit 190 determines whether or not the parking brake 132 of the vehicle EV is not operated in step S208. That is, it is determined whether or not the vehicle EV is in a state where it can travel. The vehicle control unit 190 returns to step S205 when the parking brake 132 of the vehicle EV is operated (S208: NO), while the step returns to step S205 when the parking brake 132 of the vehicle EV is not operated (S208: YES). The process proceeds to S206.

  Next, the vehicle control unit 190 sets the IC card slot 171 in the locked state in step S206. That is, while the vehicle EV is running, the IC card 40 inserted into the IC card slot 171 is locked so as not to be removed, and this routine is terminated.

  Note that in step S207, the vehicle EV usage date and time is reached, and if the IC card 40 of the user U is not detected even after a predetermined time has elapsed (S207: YES), the user U who has reserved the usage of the vehicle EV will use it. Since it can be estimated that the intention has been lost, the vehicle control unit 190 ends this routine.

  FIG. 5 shows that when the user U drives the vehicle EV and arrives at the second parking lot P2, which is the destination, and the vehicle EV is abandoned (returned) to the second parking lot P2, the vehicle control unit 190 The routine to execute.

  In step S301, the vehicle control unit 190 determines whether or not the position where the shift lever 161 of the vehicle EV is disposed is “P” (parking: parking). When it is determined that the position at which the shift lever 161 is disposed is “P” (S301: YES), the vehicle control unit 190 proceeds to step S302.

  Next, the vehicle control unit 190 determines in step S302 whether the parking brake 132 of the vehicle EV is operating. When the parking brake 132 of the vehicle EV is operating (S302: YES), the vehicle control unit 190 proceeds to step S303.

  Next, in step S303, the vehicle control unit 190 determines whether or not the light 121 of the vehicle EV is off. When the light 121 of the vehicle EV is off (S303: YES), the vehicle control unit 190 proceeds to step S304.

  Next, the vehicle control unit 190 unlocks the IC card slot 171 in step S304. That is, since the shift lever 161 is arranged at the position “P”, the parking brake 132 is operated, and the light 121 is turned off, it can be determined that the vehicle EV is parked. The card slot 171 can be removed.

  On the other hand, when the shift lever 161 is not disposed at the position “P” (S301: NO), when the parking brake 132 is not operated (S302: NO), when the light 121 is on (S303: NO). , It can be estimated that the vehicle EV has not stopped yet. In these cases, the vehicle control unit 190 continues to wait for the vehicle EV to stop.

  Next, the vehicle control unit 190 determines whether or not the IC card 40 is removed from the IC card slot 171 in step S305. When the IC card 40 is extracted, the vehicle control unit 190 proceeds to step S306.

  Next, the vehicle control unit 190 turns off the ignition switch 151 in step S306. As a result, the state in which power can be supplied from the battery 111 to the electric motor is released.

  Next, the vehicle control unit 190 determines whether or not the IC card 40 is detected by the IC card reader 172 in step S307.
