  By the way, in the above-mentioned conventional shared vehicle management system, in order to grasp the user's needs for the setting values of each vehicle, when storing the history of setting values in the portable device, the storage capacity of the portable device must be ensured to be large. In addition, the amount of information that the management terminal reads from the portable device also increases. As a result, the labor for performing analysis or the like in the management terminal becomes excessive.

  The present invention has been made in view of the above-described conventional situation, and can reduce the storage capacity of the portable device and efficiently acquire data for grasping the user needs for the set values of each vehicle. Providing a shared vehicle management system that can be solved is an issue to be solved.

The shared vehicle management system of the present invention includes a plurality of portable devices that can be carried by a plurality of users,
A plurality of vehicles each having at least one functional device;
A management terminal for reading and writing information with each portable device,
A processing device that stores vehicle identification information that is uniquely assigned to each vehicle and setting information that activates the functional device based on a setting value, and that performs processing related to the vehicle identification information and the setting information. Provided,
Each portable device has a first storage unit that stores any one of the vehicle identification information and a second storage unit that is provided with a predetermined storage capacity and stores setting change information for changing the setting information. And
The setting change information includes fixed-length setting current value information that gives the current setting value, and the maximum value, minimum value, longest use value, average value, and median value of the setting value that characterizes the history of the setting value change A fixed-length extraction information obtained by extracting a parameter including at least one of
Each processing device reads the vehicle identification information from each portable device, and reads and writes the setting change information to and from each portable device;
Authentication means for permitting use of a specific vehicle that is the vehicle to which the specific vehicle identification information is assigned by the specific portable device that is the portable device storing the specific vehicle identification information that is the specific vehicle identification information. And
When the set value is changed when the specific vehicle is used, each processing device performs an extraction process of extracting the parameter as the extraction information from the history of the set value,
The reading / writing unit relating to the specific vehicle overwrites the set current value information and the extracted information on the second storage unit relating to the specific portable device.

  In the shared vehicle management system of the present invention, when a set value is changed when a specific vehicle is used, a parameter that characterizes the fixed-length set current value information and the change history of the set value in the second storage unit related to the portable device Is overwritten with the fixed length extraction information. That is, in this shared vehicle management system, it is not necessary to continuously store the history of setting values in the second storage unit of the portable device, and the amount of information stored in the second storage unit can be reduced. In addition, the amount of information that the management terminal reads from the portable device can be reduced.

  Therefore, in the shared vehicle management system of the present invention, the storage capacity of the portable device can be set small, and data for grasping the user needs for the set value of each vehicle can be efficiently acquired. As a result, in this shared vehicle management system, the acquired data can be effectively used for various types of analysis, and as a result, convenience when managing each vehicle and each portable device by the management terminal can be improved.

Extracting information, the maximum value of the set value, the minimum value, maximum use value, that contain at least one of mean and median. In this case, the extracted information can reliably characterize the change history of the set value by at least one of the parameters.

Each processing device intends line extraction processing for extracting the parameters from the history of the setting value to be changed when using the specific vehicle as the extraction information. In this case, since it is not necessary to give the portable device an arithmetic function or the like, the portable device can be simplified. For example, an IC card or the like can be easily adopted as the portable device.

  It is desirable that the portable device and the processing device are configured to transmit information without contact. In this case, since the trouble of connecting the portable device to a connector or the like provided on the vehicle can be saved, the convenience is further improved.

  Each processing device desirably performs a notification process for requesting information transmission to a specific portable device when the specific portable device cannot transmit information about a setting value that is changed when the specific vehicle is used. In this case, it is easy to ensure an opportunity to store the information on the change of the set value in the portable device by the notification process.

  When it is possible to transmit information to the specific portable device after the notification process, the reading / writing means related to the specific vehicle overwrites the set current value information and the extracted information on the second storage unit related to the specific portable device. Is desirable. On the other hand, when information cannot be transmitted to the specific portable device even after the notification process, it is desirable that the processing device related to the specific vehicle cancels the change in the set value this time. In this case, whether or not the change of the setting value is enabled or disabled depending on whether or not the passenger can transmit information to the portable device, for example, whether or not the IC card is placed on the card reader / writer. The convenience can be further improved.

  When the management terminal reads out information from the specific portable device, it is preferable to perform a first selection process for selecting whether or not the extracted information stored in the second storage unit can be stored for each item. In this case, since it can be selected not to store unnecessary information, the amount of information read from the portable device by the management terminal can be further reduced.

  When writing information to the portable device, the management terminal performs a second selection process for selecting whether the current set value information and the extracted information stored in the second storage unit are the previous recorded value or the standard initial value. It is desirable. In this case, since the information on the change of the setting value according to the user needs can be written in the portable device, the convenience is further improved.

  In the shared vehicle management system of the present invention, the storage capacity of the portable device can be set small, and data for grasping the user needs for the set value of each vehicle can be efficiently acquired.

It corresponds to the item. The set current value information D4 is information that gives the current set value. Extracted information D5 and D6 are obtained by extracting parameters that characterize the history of changes in set values. Specifically, the extraction information D5 is the maximum setting value. The extraction information D6 is a minimum value of the set value. As the extraction information, the longest use value, average value, or median value of the set values can be adopted.

  The setting change information D3 includes change permission information D7 shown in FIG. The change permission information D7 is a flag indicating whether or not to permit the user 9 to change the setting.

(Management terminal configuration)
As shown in FIGS. 1 and 2, the management terminal 30 is an information processing terminal such as a computer that reads and writes information with each IC card 20 and centrally manages the information. The management terminal 30 includes an IC card reader / writer 39 and a storage 31.

  As shown in FIGS. 2 to 4, the IC card reader / writer 39 performs non-contact wireless communication with the IC card 20. As will be described later, the IC card reader / writer 39 encrypts and writes one vehicle identification information D1 as usable vehicle information and setting change information D3 to the IC card 20 lent to the user 9. The IC card reader / writer 39 reads information such as setting change information D3 stored in an encrypted state on the IC card 20 returned from the user 9.

  The storage 31 stores a vehicle information management data table 32, a user control setting management data table 33, and an IC card information management data table 34.

  As shown in FIGS. 3 and 4, the vehicle information management data table 32 manages the vehicle identification information D1 of each vehicle 10 in a state of being divided into a management unit ID, a group ID, and an individual ID within the group. The vehicle identification information D1 is written to each IC card 20 based on these pieces of information.

  In the user control setting management data table 33, setting change authority information indicating whether or not each user 9 has the authority to change the setting when using the vehicle 10, and when each user 9 changes the setting of the vehicle 10 The control setting initial value, the control setting history maximum value, the control setting history minimum value, and the like referred to in the above are centrally managed, and the setting change information D3 is written to each IC card 20 based on these information. The control setting initial value, the control setting history maximum value, the control setting history minimum value, and the like store a previously recorded value that is updated as needed and a standard initial value that is set in advance.

  In the IC card information management data table 34, the IC card fixed ID of each IC card 20, vehicle permission information that is vehicle information that can be used by each IC card 20, and the user 9 who carries each IC card 20 The user IDs and the like are centrally managed, and the contents are updated as needed when each IC card 20 is lent or returned.

(IC card lending setting process)
In the shared vehicle management system 100, when the IC card 20 is lent out to the user 9, the IC card rental setting process shown in FIG. 5 is executed between the management terminal 30 and the IC card 20. Various arrows shown below [when lending IC card] in FIG. 3 indicate the exchange of information performed between the management terminal 30 and the IC card 20 in this process. In this process, the IC card 20 is placed on the IC card reader / writer 39 of the management terminal 30 so as to be capable of non-contact wireless communication.

  First, in step S <b> 11, the management terminal 30 selects one vehicle 10 that is permitted to be used by the user 9 from the plurality of vehicles 10, and sets a use-permitted vehicle.

  Next, in step S12, the management terminal 30 selects and sets the user ID of the user 9 from whom the IC card 20 is lent.

  Next, in step S <b> 13, the management terminal 30 reads the IC card unique ID of the IC card 20 to be lent by the IC card reader / writer 39.

  Next, in step S14, the management terminal 30 associates the use-permitted vehicle set in step S11 and the user ID set in step S12 with the IC card unique ID read in step S13.

  Next, in step S15, the management terminal 30 uses the IC card reader / writer 39 to lend the vehicle identification information D1 uniquely assigned to the use-permitted vehicle set in step S11. Write in encrypted form.

  Next, in step S <b> 16, the management terminal 30 determines whether or not to select the previous recorded value when writing the setting change information D <b> 3 in the second storage unit 22 of the IC card 20. Step S16 is an example of the “second selection process” in the present invention. In addition, when writing the setting change information D3 to the second storage unit 22 of the IC card 20, the management terminal 30 determines whether each user 9 selects the previous recorded value or the standard initial value. Needs are remembered.

  If “Yes” in step S16, the process proceeds to step S17. In step S17, the management terminal 30 sets the setting current value information D4 of the setting change information D3 associated with the user ID set in step S12, and the maximum value D5 and the minimum value D6 of the setting values as the extraction information. The change permission information D7 is written in an encrypted state in the second storage unit 22 of the IC card 20 on the basis of the previous record value information stored in the user control setting management data table 33. Then, the IC card lending setting process ends.

  On the other hand, if “No” in step S16, the management terminal 30 determines that the standard initial value has been selected, and proceeds to step S18. In step S18, the management terminal 30 sets the setting current value information D4 of the setting change information D3 associated with the user ID set in step S12, the maximum value D5 and the minimum value D6 of the setting values as extraction information, and The change permission information D7 is written in an encrypted state in the second storage unit 22 of the IC card 20 based on the standard initial value information stored in the user control setting management data table 33. Then, the IC card lending setting process ends.

  Thus, the IC card 20 in which the vehicle identification information D1 and the setting change information D3 are written by the IC card rental setting process is lent to the user 9. The user 9 carries the IC card 20 and moves to the vehicle 10 to be used.

(Vehicle use start processing)
In the shared vehicle management system 100, when the user 9 starts using the vehicle 10, a vehicle use start process shown in FIG. 6 is executed between the vehicle 10 and the IC card 20. Various arrows shown below [at the start of vehicle use] in FIG. 3 indicate the exchange of information performed between the vehicle 10 and the IC card 20 in this processing. During this process, the IC card 20 is placed on the IC card reader / writer 19 of the vehicle 10 so as to be capable of non-contact wireless communication.

First, in step S <b> 21, the IC card reader / writer 19 of the processing device 11 of the vehicle 10 reads the vehicle identification information D <b> 1 as the use-permitted vehicle setting from the IC card 20. Authentication unit 13 decrypt the vehicle identification information D1 read by the IC card reader / writer 19.

  Next, in step S22, the authentication unit 13 receives the vehicle identification information D1 stored in the EEPROM 13A, that is, the own vehicle ID, and the vehicle identification information D1 read from the IC card 20, that is, the permitted vehicle setting. Determine whether they match.

  If “No” in step S22, the authentication unit 13 determines that the use of the host vehicle cannot be permitted depending on the IC card 20, and proceeds to step S23. In step S23, the authentication unit 13 sets the own vehicle in a vehicle use prohibited state. That is, the functional device 12 is maintained in an inoperable state. Then, the vehicle use start process is terminated.

On the other hand, if “Yes” in step S22, the authentication unit 13 determines that the use of the host vehicle can be permitted by the IC card 20, and proceeds to step S24. In step S24, the IC card reader / writer 19 reads the setting change information D3 from the IC card 20. Authentication unit 13 decrypt the setting change information D3 which is read by the IC card reader / writer 19.

Next, in step S25, the authentication unit 13, based on the setting current value information D4 of setting change information D3 that decrypt, and the maximum value D5 and the minimum value D6 settings as extraction information, ECU14～16 The setting information D2 stored in is set. The authentication unit 13, based on change permission information D7 of setting change information D3 that decrypt, sets the setting change authorization of the stored configuration information D2 to ECU14～16.

  Next, in step S26, the authentication unit 13 sets the own vehicle in a vehicle use permission state. That is, the function device 12 is changed to a state where it can be operated. Then, the vehicle use start process is terminated.

  Thus, the vehicle 10 that has been permitted to use the vehicle by the vehicle use start process is used by the user 9 for work such as cargo handling.

(Setting change processing)
In the shared vehicle management system 100, when the user 9 changes the setting of the control items including the control items 1 to 7 described above with respect to the setting information D2 of the vehicle 10, between the vehicle 10 and the IC card 20, FIG. The setting change process shown is executed. Various arrows shown below [when setting is changed] in FIG. 4 indicate the exchange of information performed between the vehicle 10 and the IC card 20 in this process. During this process, the IC card 20 is placed on the IC card reader / writer 19 of the vehicle 10 so as to be capable of non-contact wireless communication.

  First, in step S31, the ECUs 14 to 16 of the processing device 11 of the vehicle 10 refer to the setting information D2 stored in the ECUs 14 to 16 for the control items for which the setting change input operation has been performed by the user 9, and change the settings. Change the settings if you have permission.

  Next, in step S <b> 32, the authentication unit 13 determines whether the IC card reader / writer 19 can communicate with the IC card 20.

  If “Yes” in step S32, the process proceeds to step S36.

  On the other hand, if “No” in step S32, the process proceeds to step S33. In step S <b> 33, the authentication unit 13 performs notification processing for requesting the user 9 using the vehicle 10 to place the IC card 20 on the IC card reader / writer 19. The notification process is performed by, for example, a voice message or a blinking lamp. Step S33 is an example of the “notification process” in the present invention.

  Next, in step S <b> 34, the authentication unit 13 determines whether or not the IC card reader / writer 19 can communicate with the IC card 20.

  If “Yes” in step S34, the process proceeds to step S36.

  On the other hand, if “No” in step S34, the process proceeds to step S35. In step S35, the authentication unit 13 causes the ECUs 14 to 16 to perform processing for canceling the current setting change. That is, the authentication unit 13 determines that the user 9 using the vehicle 10 has refused to write to the IC card 20, and invalidates the current setting change. Then, the setting change process ends.

When the process proceeds from step S32 or step S34 to step S36, the IC card reader / writer 19 reads the vehicle identification information D1 as the use-permitted vehicle setting from the IC card 20. Authentication unit 13 decrypt the vehicle identification information D1 read by the IC card reader / writer 19.

  Next, in step S37, the authentication unit 13 receives the vehicle identification information D1 stored in the EEPROM 13A, that is, the own vehicle ID, and the vehicle identification information D1 read from the IC card 20, that is, the permitted vehicle setting. Determine whether they match.

  If “No” in step S37, the authentication unit 13 determines that the setting change of the own vehicle cannot be permitted depending on the IC card 20, moves to step S35, performs the above-described processing, and then changes the setting. The process ends.

  On the other hand, in the case of “Yes” in step S37, the authentication unit 13 determines that the setting change of the own vehicle can be permitted by the IC card 20, and proceeds to step S38. In step S38, the ECUs 14 to 16 update and store the setting current value information D4 and the maximum value D5 and the minimum value D6 of the setting value as the extraction information based on the current setting change. Step S38 is an example of the “extraction process” in the present invention.

  Next, in step S39, the authentication unit 13 encrypts the set current value information D4 updated in the ECUs 14 to 16, and the maximum value D5 and the minimum value D6 of the set values as extraction information. The IC card reader / writer 19 overwrites the second storage unit 22 of the IC card 20 with the set current value information D4 encrypted by the authentication unit 13 and the maximum value D5 and the minimum value D6 of the set value as the extraction information. To do.

Next, in step S40, the authentication unit 13, set the current value information D4 stored in the IC card 20, determines whether to update the maximum value D5 and the minimum value D6 settings as extraction information .

  If “No” in step S40, the authentication unit 13 determines that the IC card 20 to be updated has not been allowed to change the setting of the host vehicle, and proceeds to step S35. Specifically, when the IC card 20 is removed from the IC card reader / writer 19 of the vehicle 10 or the like, “No” is determined in step S40, and the process proceeds to step S35. In step S35, after performing the above-described processing, the setting change processing is terminated.

  On the other hand, if “Yes” in step S40, the authentication unit 13 determines that the current setting change can be confirmed, and proceeds to step S41. In step S41, the authentication unit 13 allows the ECU 14 to 16 to change the current setting, and confirms the changed content of the setting information D2. Then, the setting change process ends.

(IC card return record processing)
In the shared vehicle management system 100, when the user 9 returns the IC card 20, the IC card return recording process shown in FIG. 8 is executed between the management terminal 30 and the IC card 20.
