2. Description of the Related Art A rental car is a form in which a plurality of users use an automobile. Generally, rental procedures are complicated for rental cars, and it is desired to simplify and speed up the rental procedures. Japanese Patent Laid-Open No. 1-100671 discloses a terminal card installed in a place where a user inserts a user-specific IC card into a reservation device to make a rental car rental reservation automatically and rents a car on the day of use. It is described that when the IC card is inserted into the reader, the identification information of the vehicle assigned to this user is displayed on the display panel according to the advance reservation procedure, and a predetermined protocol is written in the IC card. . The IC card in which this protocol is written serves as an opening / closing key for the door of the automobile to which the IC card is assigned and a starting key for the automobile. In this system, reservations and lending procedures are performed by automated self-service, but it is necessary to perform lending after making reservations, which is not suitable for daily use such as daily commuting.

As a method of renting a rental car by self-service using an IC card, Japanese Patent Laid-Open No. 3610/1994 has been proposed.
No. 0 publication describes that an IC card is given to a contract user, and this IC card is used as a key for a gate of a storage place for construction machines, vehicles, etc., and as a key for a power switch of a rental vehicle, etc. ing. With this system, users are completely self-service and can select and use any machine or vehicle at any time, but even if such a system can be configured for a small number of users, many users can use it. It is necessary to prepare a large parking lot and make a large number of machines or vehicles stand by in order to rent out any machine or vehicle for self-service at any time.

In order to further improve the efficiency of the rental car rental procedure, Japanese Patent Laid-Open No. 8-101993 discloses a computerized dispatch center in which a user inserts a user identification card into a card reader at a stop. There is described a car rental system in which a chip card coded peculiar to a rental car to be rented is issued when a rental car is reserved by communication and a reserved user card is inserted into an automatic machine at a stop. In this system, this chip card serves as the vehicle door key and the release key for the anti-theft device. The maximum rental use time is stored in this chip card, and after the use time is exceeded, management is performed using the chip card such that the vehicle is not opened with the chip card. This system, like other conventional rental car systems, is merely a system for temporarily using a rental car at a special time such as traveling.

[0005]

The above-mentioned prior art rental car system is for utilizing the rental car as a temporary or temporary means of transportation during travel or other special occasions, and the relationship with each user. The rental car was not used as a means of transportation in everyday life. As a daily use form of a vehicle, there is use as a part of commuting means. Especially for office workers who live in residential areas near the city and commute to the city, it is convenient to use a car to get to and from the transportation terminal such as a railroad, but the number of parking lots near the transportation terminal is limited. Often not available. Even if the parking lot can be used, the commuters' cars will occupy the parking lot space from morning until evening, and those who go out by car near the daytime traffic terminal for shopping or other business will find the parking lot insufficient. You will be bothered.

Therefore, it is desired to realize a vehicle sharing system in which the user can use the vehicle constantly in daily life and the vehicle does not occupy the parking space for a long time. Further, in consideration of the environment, it is desired to increase the use of electric vehicles that use a battery as at least a part of power.

However, in such a shared vehicle, particularly in an electric vehicle that uses a battery as at least a part of its power, running out of battery becomes a serious problem. In particular, users of shared vehicles may be aware of the amount of battery power remaining for their own running, but do not consider users after returning the vehicle. When a user of the vehicle uses the vehicle, the user may not be able to use the vehicle due to insufficient battery capacity.

Therefore, an object of the present invention is to provide a rented vehicle capable of preventing battery exhaustion in a vehicle sharing system in which a plurality of users can constantly use a plurality of shared vehicles. .

[0009]

[Means for Solving the Problems] The above-described problems are solved by a plurality of electric vehicles for lending equipped with an IC card read / write device, a first pattern for returning a morning vehicle and renting in the evening, and a renting out an morning vehicle and returning in the evening. An IC card for recording information including a member's identification code, which is issued to members of a plurality of patterns including at least the second pattern, and a lending terminal device for writing a member's usage pattern into the IC card when renting a vehicle. An electric vehicle for lending, which uses a battery for at least part of power for a vehicle sharing system provided, wherein a usage pattern is recorded in an IC card at the time of issuance, or a usage pattern by a lending terminal device at the time of lending. Can be written, and the determination means for determining the usage pattern of the member read from the IC card, and the remaining capacity of the battery When the usage pattern determined by the determination means is the first pattern, the remaining capacity of the battery measured by the measurement means is displayed. When the usage pattern is a pattern other than the first pattern, the capacity obtained by subtracting the reserved battery capacity required for the members of the first pattern to travel in the evening from the remaining battery capacity measured by the measuring means is calculated. And an electric vehicle having a control means for displaying the remaining capacity on the display means.

Further, different IC cards may be prepared according to usage patterns and issued to members according to usage patterns. For example, an IC card having an uneven display or a code indicating a usage pattern can be issued to a member so that the type of the IC card can be seen from the appearance. In this case, the usage pattern is recognized by determining the type of IC card.

According to the present invention, the remaining capacity of the battery of the electric vehicle is displayed according to the usage pattern of the user of the shared vehicle, so that the battery of the shared vehicle used by a plurality of users can be prevented from running out. it can.

DETAILED DESCRIPTION OF THE INVENTION

1. System Concept In the vehicle sharing system of the present invention, a plurality of registered users share a plurality of vehicles according to their respective usage time zones. FIG. 1 illustrates the general concept of the system of the present invention. In the morning, the user uses the rental vehicle from the residence 3 to the parking lot 1 near the transportation terminal used for commuting such as a railroad, and the regular pattern user who returns from the parking lot 1 to the residence 3 in the evening, that is, a regular user, In the morning, the user can rent a vehicle from the parking lot 1 near the traffic terminal to the work place 5 and return to the parking lot 1 near the traffic terminal from the work place 5 in the evening. However, the present invention is not limited to this, and regular users during the daytime and seemingly non-regular users can also use this system. A typical example of a reverse user is a company in the area, which uses a rental vehicle as a transportation means from an employee's transportation terminal and uses it for business during the daytime.

The parking lot is preferably a parking lot such as a shopping center or a shopping mall near the transportation terminal. Such facilities have large parking lots for shoppers, but are usually closed and unused during morning and evening commuting hours. A contract is made with such a facility so that it can be used during morning and evening commuting hours, and a port terminal of the system of the present invention is installed. In this system, rental vehicles are typically parked in these parking lots because the user with a positive pattern uses the car to go to work in the morning and returns the vehicle at the port terminal in the parking lot, and then the reverse pattern. It is the time until the user rents a car. In addition to this, in the daytime, a parking space for a user who rents out a rental vehicle during the daytime is required.

As an example, a user A of a positive pattern who lives in a residential area on the outskirts of a small city X and works for a company in a city center Y has to take a train at 8 am to arrive at his office at 9 am. . User A arrives at the parking lot of the shopping center near the station at 7:45 every morning, parks the car at a predetermined position, and performs the automatic return procedure at the port terminal device.
Head to the station. User B, who works in a company in this small city X and commute by train from afar, arrives at the station in this small city X at 8:30 am to arrive at the office in the small city X at 9:30 a.m. Perform automatic lending procedure at the port terminal device at the car park, rent out the vehicle at 8:40, and head to your work place. If user B rents a vehicle returned by user A, the time when this vehicle is parked in the parking lot is 55 minutes from 7:45 to 8:40.

In this system, it is preferable that the number of users of the normal pattern and the number of users of the reverse pattern are about the same, but it is usually predicted that the number of users of the normal pattern exceeds the number of reverse users. To be done. In that case, that number of vehicles is left in the parking lot during the day and is provided for use by daytime regular users and seemingly users. Therefore, the parking space occupied by the vehicles of this system in the daytime is equal to or less than the number of vehicles corresponding to the difference between the number of normal pattern users and the number of reverse pattern users.

The rental vehicle to be used is preferably an electric vehicle that uses a battery as at least a part of its power in consideration of the environment, but is not limited to this, and may be a normal gasoline vehicle. . When an electric vehicle is used, it is economical to charge the battery by the charger 4 using the nighttime electricity charge in the home garage of the regular user. A full-time user uses a fully charged car at night to go to work in the morning, and rides to the parking lot 1 near a transportation terminal such as a train used for commuting. Here, the regular user uses the port terminal device 2 in the parking lot to return this automobile by an automatic procedure. In the following description, the rental vehicle is an electric vehicle that uses a battery as at least a part of its power. A battery-powered vehicle is not only a vehicle that runs entirely on batteries, but also a vehicle that has a gasoline engine and a motor and that switches between the engine and the motor depending on the situation. Means a car. Hereinafter, such a vehicle is referred to as an electric vehicle or an electric vehicle.

As described above, most of the rental vehicles used in this system are merely placed in the parking lot 1 for a relatively short time in the morning and evening, and most of the time, regular users or reverse users and daytime users are used. It doesn't occupy the parking lot for a long time because it is used by or is placed in the garage of regular users. In addition, since the hours used by regular users and reverse users in the parking lot 1 are commuting hours and are different from the hours used by the shopping customers in the parking lot 1, the parking lot is expanded to introduce this system. The need to do it is low. Thus, according to this system, the free time in the parking lot can be effectively used.

One form of reverse user is daytime business use by businesses in the area. In this case, the company hired a registered employee to rent a car at a parking lot 1 near a transportation terminal using a corporate IC card for business use by multiple employees, and in the evening Will be returned to Parking Lot 1 when he returns home.

Instead of such a process, a prompt for prompting the input of "Vehicle management No." is displayed in response to the selection of "Vehicle information screen" from the menu screen of FIG. Subsystem 6 according to the input of
0 is the vehicle management number. The vehicle performance table 42 and the vehicle master table 41 are inquired with the key as a key, and the vehicle management number. It is also possible to extract the data from a predetermined field of the record and put it in a predetermined form to display the screen of FIG.

3. Membership management Those who wish to join the vehicle sharing system of the present invention fill in the necessary items on the membership application form and apply. In addition to general management information such as the person's name, address, work place, etc., the membership application form includes holiday patterns such as weekends and holidays, usage patterns such as normal use and reverse use, and port terminal devices. The time slot for renting the vehicle, the time slot for returning the vehicle at the port terminal device, and the like are entered.

The operator who receives the membership application form selects a member information screen from the menu screen (FIG. 4) displayed on the display device of the office terminal 23 shown in FIG. 2, and the member information list screen displayed in response to this. When “enroll” is selected from, the member management subsystem 30 sends the object of the admission acceptance form to the office terminal device 23, and the enrollment acceptance screen shown in FIG. 7 is displayed. The operator fills in this admission acceptance screen based on the entry application form. In the field of the usage pattern, normal use / 10k, reverse use / 20k, daytime / 2
Enter the usage pattern of the shared vehicle and the planned mileage, such as 0k. If the applicant is a corporation, the usage pattern is entered as, for example, corporation / 10k,
In the case of personal daytime use, it is input as daytime / 20k. When the input is completed and the enter key is pressed, the input content is recorded in the member master table of FIG. 2 as a prospective member.

The operator returns the display on the display device of the terminal 23 to the menu screen (FIG. 4), and a "member registration number confirmation screen" is displayed.
Select and enter or click parameters such as the business name. Referring to FIG. 8, in response to this input, the query means 34 of the member management subsystem 30 uses the “use pattern” field as a key and the member master table 3
1 is searched and the number of registered members for each usage pattern is entered in the counting means 35. The member management subsystem 30 simultaneously accesses the capacity table 32, reads the capacity of each usage pattern, and calculates the difference calculation means 36 and the display control means 37.
Put in. The difference calculating means 36 calculates the difference between the number of registered members for each usage pattern totaled by the usage pattern totaling means and the capacity for each usage pattern read from the capacity table 32. The number of people for each usage pattern read from the capacity table 32, the number of registered members for each usage pattern aggregated by the aggregation means, and the difference value calculated by the difference calculation means 36 are sent to the display control means 37. Display control means 3
7 puts these data in a predetermined form and displays it on the display device 38 in a format as shown in FIG.

The counting, difference calculation, and display control described above are performed by the member management subsystem 30 in the form of a query.
It can be realized by integrating objects, form objects, and report objects.

In the above description, the total of all usage patterns is displayed on the screen in response to the operator's input as shown in FIG. 9, but the specific usage pattern for which the membership application is made is used as a key. It is also possible to search the member master table 31 and access the capacity table 32 similarly using a specific usage pattern as a key to display such information.

4. When the vehicle rental and return management enrollment application procedure is completed, an IC card in which a member-specific identification code is recorded in a memory is issued. An IC card is a plastic card that is about the same size as a credit card that incorporates semiconductor memory.
Various kinds of information can be written or read using the writing device. In addition to the member identification code being recorded on the IC card, the information described later is written.

When the IC card is inserted into the IC card insertion port of the port terminal device 2 (FIG. 2), the information about the rented vehicle is read from the IC card, and it is first determined whether or not the vehicle is rented. . If the vehicle is not rented, a prompt asking whether to proceed with the vehicle lending procedure, for example, a message "Are you sure you want to lend the vehicle?" And "Yes" and "No" are displayed on the display screen of the port terminal device . This display screen is preferably a touch panel, in which case the user touches "Yes" to proceed with the vehicle rental procedure, and the user touches "No" to respond to the signal generated accordingly. Then, the terminal device ends the operation and sends out the IC card.
Alternatively, instead of terminating the operation, a menu for contacting a service such as inquiry about accumulated usage charges may be displayed. The display screen does not necessarily have to be a touch panel, and may be a combination of a normal CRT display device and a key input device. The port terminal device 2 has a structure similar to that of an automatic transaction device such as a bank, but can also be configured by a general computer terminal device.

When the user touches "Yes", the port terminal unit 2 responds to the signal generated in response to this by pressing the ten key and "Enter password" on the display screen.
Is displayed. Referring to FIG. 10, when the password is input by the user, the port terminal device 2
Sends this password to the member management subsystem 30, and the subsystem 30 checks this password against the password recorded in the member master table 31. If the collations match, the vehicle performance management subsystem 60
Uses the member's usage pattern information read from the IC card as an extraction condition to extract a vehicle suitable for the usage pattern from the vehicle master table 41 and the vehicle performance table 42. When there are a plurality of vehicles suitable for lending, One is selected by a vehicle allocation logic described later, and the vehicle number and information associated with this vehicle are put in a preset form and sent to the port terminal device 2. The port terminal device 2 displays the vehicle number on the display screen of the port terminal device 2 according to this form object, and writes it in the IC card. At that time, in addition to the vehicle number, information related to the rented vehicle such as vehicle key number, lending date, lending time, lending business, lending port, starting mileage, lending time, charge amount, and damage Also write on the IC card.

The user stores the vehicle number displayed on the display screen of the port terminal device 2, goes to the parking position of the vehicle, starts the vehicle, and starts using the vehicle. Alternatively,
The port terminal device 2 may be provided with a tape printer, and the vehicle number may be printed and held by the user. Even when the printer is not used, the user can display the information of the IC card on the portable IC card reader for viewing, so that he / she can safely forget the vehicle number. As described above, the vehicle renting procedure is automatically performed by the user's simple operation of the port terminal device 2 without the help of a staff member of the renting entity, so that a speedy lending operation is realized.

The car is also equipped with an IC card read / write device, and when the specific information recorded on the IC card inserted by the user, such as the vehicle number and the vehicle key number, matches with itself, Turn on the engine or motor starting circuit. By doing so, mechanical keys can be omitted. Of course, a mechanical key and an IC card may be used in combination.

The in-vehicle read / write device writes the use start time, the use end time, the remaining charge before use, the travel distance before use, the travel distance after use, and the travel distance on the IC card as vehicle operation information. Depending on the design of the system, only some of this information may be written to the IC card, or additional information may be written.

The return of the vehicle is promptly and automatically performed by the user operating the port terminal device 2 similarly to the rental. That is, the user stops the vehicle to be returned at a predetermined position in the parking lot 1 where the port terminal device 2 is located, removes the IC card from the in-vehicle read / write device, and inserts it into the IC card read / write device of the port terminal device 2. To do. Based on the member information and the vehicle information read from the IC card, the port terminal device 2 determines that this user is renting the vehicle, and displays the message "OK for return procedure" on the display screen. Display with "Yes" and "No" prompts. When “Yes” is selected, the port terminal device 2 transfers the member information and vehicle information read from the IC card to the database system 10 via the communication network 20. Referring to FIG.
The member achievement management subsystem 50 and the vehicle achievement management subsystem 60 of the system 10 respond to this, and provide these pieces of information to the member achievement table 32 and the vehicle achievement table 4.
2, the predetermined fee is calculated by executing a predetermined query, put in a predetermined form or report object, and transferred to the port terminal device 2. Port terminal 2
Displays the usage fee on the display screen accordingly.

5. Vehicle allocation When renting a vehicle, the database system 10
Using the member information read from the IC card inserted in the port terminal device 2 as a key, the usage pattern information of the member is extracted from the member master table 31, and the traveling distance information per lending included in the usage pattern is obtained. As a key, a vehicle having a remaining charge amount corresponding to the travel distance is extracted from the vehicle performance table 42. A database program may be set such that the member's mileage information, which is a key in vehicle allocation, is the average mileage of the member in the past certain period plus a margin. Also,
When renting to a user who uses in reverse or in the daytime, the mileage added with the mileage equivalent to the average return distance of regular members so that the same vehicle can be lent to a regular member after returning the vehicle The database system can be configured to be used as a key.

The member record table 32 creates a record for each lending and returning of each member. FIG. 11 shows the meanings and attributes of some fields included in this table. The underlined fields in this figure record the results of each use (trip), that is, each time the IC card is inserted into and removed from the IC card read / write device of the vehicle. Such data can be stored in on-board ICs.
It is recorded on the IC card by the card read / write device and read by the port terminal device 2. "Total mileage"
The field indicates the mileage per rental.
Although not shown in the figure, an “average mileage” field may be provided to record the average value of the total mileage of each loan for a certain period in the past, for example, one month. This field is a function of the "total mileage" field and the return date, and the sum of the values in the "total mileage" field for records whose date in the "return date" field is within 1 month from the present time is calculated for this period. Calculated by dividing by the number of records. That is, the "average mileage" field is automatically updated by executing this function every time a record of the member is added.

Referring to FIG. 12, the system inquires the member performance table of the member in response to the vehicle allocation request (101), retrieves the value of the "average distance traveled" field (102), and the travel margin is set to this value. Value D with minute a added
The (threshold value D) is calculated (103), the "remaining distance traveled" field of the vehicle table is searched with D as a key, and the vehicle information of the record having a larger value than the search key is extracted (104).

In the above explanation, the membership record table 3
It was explained that the "Average mileage" field, which is a function field, is provided in 2 and that the average mileage is automatically calculated each time a record is added and is recorded in the "Average mileage" field. It is also possible to incorporate a calculation command into a query (inquiry formula) for accessing 32 and calculate the average mileage of the member when executing the query.

When the vehicle is returned, the port terminal device 2
Reads this information from the IC card and adds it as a new record in the related table. These data are used for the above-described vehicle allocation management.

7. Battery life prevention warning device The remaining capacity of the battery of the rented vehicle is directly related to the mileage of the vehicle and is a very important matter for the user. Therefore, the display of the remaining capacity of the battery must be confirmed by the user at a glance even while the vehicle is driving. Hereinafter, a warning device for preventing battery exhaustion will be described with reference to FIGS. 14 and 15 described above.

In FIG. 14, the remaining capacity of the battery is indicated by the remaining capacity meter 84, which indicates the actual remaining capacity (AH) of the battery. The remaining capacity of the battery is monitored by an integrated wattmeter or the like that monitors the integrated power of battery discharge. That is, the current remaining battery capacity is obtained by subtracting the integrated power consumed (discharged) during traveling from the remaining battery capacity at the start of use of the vehicle. The current power consumption of the vehicle while running is indicated by a power consumption meter 85, which is displayed next to the remaining capacity meter 84 of the battery in the shape of an inverted triangle. It can be grasped visually. In addition to the integrated power meter, the charge amount of the battery can be measured by an instantaneous discharge method in which the voltage drop of the battery is observed by discharging the battery for a certain fixed time (for example, 1/100 sec).

Here, it suffices if the user of the vehicle can know from the remaining capacity (AH) of the battery, more specifically, how much further the vehicle can travel by the distance (km). The remaining travelable distance meter 86 indicates the actual travelable distance of the vehicle, and in FIG. 14, the maximum travelable distance of 180 km can be displayed. This power consumption is directly related to the travelable distance (km) of the vehicle, and the greater the power consumption, the shorter the travelable distance of the vehicle. Therefore, the travelable distance is calculated based on the battery remaining capacity and the power consumption. By seeing this display, the user can
You can see at a glance how much you can run. In addition, as a method of displaying the travelable distance, a digital numerical value direct display or an analog method meter needle display may be used.

By the way, the user of the rented vehicle is not always aware of the remaining capacity meter 84 and the remaining travelable distance meter 86 during traveling, and for some reason, the vehicle is used over the distance beyond the utilization application. It is also possible to do it. In such a case, a warning display method is adopted as a method of notifying the vehicle user, and it is taken to prevent the battery from running out. As one of the warning display methods, when the remaining battery capacity falls below a certain amount,
The charge request lamp 87 blinks or lights up. For example, this may start blinking when the remaining battery capacity is 15 km or less after converting into the travelable distance, and may be turned on when the remaining battery capacity is 5 km or less. By blinking or lighting the charge request lamp 87, the vehicle user can recognize that the battery has a small remaining capacity (that is, a short travelable distance).

In addition, a warning display 89 is provided to show a certain predetermined content, for example, a warning of a seat belt check or a half door. A battery check panel can also be included here, and if any warning state occurs, the corresponding panel will blink or light up according to the contents shown on each panel, and that warning state will be used by the vehicle. It may be possible to inform the person.

Further, the multi-information 88 is
When the warning display 89 blinks or lights up, the content of the warning is displayed, and more specifically the vehicle user can be notified of the content of the warning.

FIG. 15 shows a block diagram of a process for displaying a warning for preventing the battery from running out. The warning display in this case is a warning display that occurs when the vehicle user's normal usage distance is exceeded.
First, as described above with reference to FIG. 12, the threshold value D, which is a value obtained by adding the travel margin to the average mileage of the vehicle user, is determined by the port terminal device for lending and returning when renting the vehicle. It is recorded in the user's IC card (50
1).

When the IC card is inserted into the IC card read / write device 80 (FIG. 13) in the vehicle, the threshold value D recorded in the IC card is read from the IC card read / write device 80. Next, the actual traveling distance C from the time the vehicle is rented to the present is detected (502), and this actual traveling distance C is compared with the threshold value D read from the user's IC card as described above (503). ). As a result of the comparison, if the actual traveling distance C exceeds the threshold value D, a warning is displayed (506). In this case, the travelable distance (average remaining travel distance) B is calculated (505) from the battery remaining capacity (504) detected by the battery remaining capacity meter, based on the power consumption of the running vehicle, and the calculated travel is calculated. The possible distance B may be displayed as a warning display in the multi-information 88 shown in FIG. 14 (506).

In addition to the method of displaying on the panel shown in FIG. 14, the warning display in this case is provided to the driver by a sound (for example, a beep sound or a human voice) separately from or together with the panel display. Can be notified.

8. As described above, when the usage pattern of the shared vehicle for displaying the remaining battery capacity is according to the users of the normal pattern and the users of the reverse pattern (business users, temporary daytime users, etc.), the shared vehicles used during the daytime are ,
In the evening, it is used for returning home of users of the positive pattern, and the user of the positive pattern charges the battery at night. In this case, a user who uses a shared vehicle in the daytime in a reverse pattern may be aware of the remaining battery capacity of his / her own drive, but does not consider the user after returning the vehicle, so it is very close. The battery may be consumed up to, and the battery remaining capacity of the user returning home in the correct pattern may be insufficient.

Therefore, in order to smoothly operate the above-described shared vehicle use system, the user of the normal pattern can certainly return home, and the user of the normal pattern can surely charge the battery of the shared vehicle at night. That is an important point.

Therefore, as shown in FIG. 16, the display of the remaining battery charge of the user of the normal pattern and the user of the pattern other than the correct pattern (for example, the reverse pattern) is switched so that the user of the correct pattern can surely return home. To do so. When the user inserts the IC card into the IC card read / write device 80 (FIG. 13) in the rental vehicle, the management ECU 81 (FIG. 13) causes the management ECU 81 (FIG. 13) to read the usage pattern data of the user. Based on the above, it is determined whether the vehicle user is the user of the normal pattern or the user of the reverse pattern (602).

If the user has a positive pattern, the actual remaining battery capacity is displayed as it is on the remaining capacity meter 84 (603).
Further, the actual travelable distance is calculated based on the battery remaining capacity and displayed on the remaining travelable distance meter 86.

When it is determined that the vehicle user is the user of the reverse pattern from the data of the usage pattern of the member read out from the IC card, the actual battery remaining capacity is used to return the user of the normal pattern to the home. The remaining battery capacity obtained by deducting the remaining battery capacity and the battery capacity for providing a certain amount of margin (both are collectively called the reserved battery capacity) is displayed as the current remaining battery capacity.
Further, the travelable distance is calculated from the battery remaining capacity thus calculated and displayed on the remaining travelable distance meter 86 (60
Four). This reserved battery capacity may be calculated by using the average of the declared travel distances of the users in the plurality of positive patterns, or may be calculated based on the average of the usage records of the users in the plurality of positive patterns for a certain period.

When based on the declared travel distance, the data of the field of the usage pattern included in the member master table 31 (FIG. 10) is used. When based on the usage record, the travel distance field of the member performance table 32 (FIG. 10) is used. Data is used. The reserved battery capacity thus calculated is recorded in the member master table of the member having the reverse pattern, and the port terminal device 2 sets the I
Written to C card. This reserved battery capacity may be recorded in the vehicle performance table instead of the member master table, and may be written in the IC card when renting to the user of the reverse pattern or the daytime usage pattern.

By doing so, even if the user of the reverse pattern or the daytime use pattern uses the vehicle as close as possible to the battery remaining capacity displayed on the console panel, it is necessary for the user of the normal pattern to return home. This means that there is enough battery capacity left. Therefore, the user of the normal pattern can use the vehicle to go home, and the vehicle sharing system can be smoothly operated.

[0081]

According to the present invention, the display of the remaining capacity of the battery can be changed according to the usage pattern of the vehicle user, and the vehicle sharing system can be operated smoothly.
