<Operation of Near Field Communication Unit 11> Next, the operation of the near field communication unit 11 in this embodiment will be described with reference to FIG. FIG. 11 is a flowchart showing a flow of operations of the near field communication unit 11 when the vehicle state is both standby and rented.

[Standby] First, the operation of the near field communication unit 11 when the rented vehicle 10 is in a standby state will be described. The near field communication unit 11 clears the character data in the character memory 11b in the standby state (step S10).
1). This character data is a personal identification number stored at the time of the previous lending, and is cleared when the lending vehicle 10 is returned and becomes unnecessary.

As a mechanism for clearing the character data in the character memory 11b, for example, a method of clearing the state transition instruction information transmitted from the comprehensive management server 30 at the end of lending as a trigger can be considered. When the ITS / CEV vehicle-mounted device 12 receives the state transition instruction information from the comprehensive management server 30, the ITS / CEV vehicle-mounted device 12 outputs a non-rental signal to the near field communication unit 11. When the non-rental signal is input, the near field communication unit 11 can be configured to recognize that the vehicle state has transitioned from the lending state to the waiting state, and to clear the character data in the character memory 11b at that time. .

Next, the center lock / center unlock signal receiving means 11i executes the center lock / center unlock signal input processing (step S102). In the input process of the center lock / center unlock signal, the process shown in the flowchart of FIG. 12 described later is executed. However, at the present time, the proximity communication transmitter 20
Since it is assumed that the personal identification number of the user is not received from the ITS / CEV, even if the ITS / CEV vehicle-mounted device 12 receives the instruction information for permitting the lending from the comprehensive management server 30, There is no input of the center lock signal / center unlock signal from the vehicle-mounted device 12, and the process directly proceeds to step S103 here.

In step S103, the near field communication unit 11 determines whether or not the vehicle state of the rented vehicle 10 is rented out. At this moment, the personal identification number of the user is received from the near field communication transmitter 20. Since it is assumed that the ITS / CEV vehicle-mounted device 12 does not input the lending signal. Therefore, the near field communication unit 11 is the rental vehicle 1
It is determined that the vehicle state of 0 is in standby (step S1
03 / NO), the process proceeds to step S104.

In step S104, the near field communication unit 11 starts the process of receiving near field data from the near field communication transmitter 20 by the near field data receiving means 11a. Then, the near field communication unit 11 determines whether or not the near field data is received from the near field communication transmitter 20 (step S105), but it is assumed that the personal identification number of the user is not received at this time. Therefore, it is determined that the proximity data has not been received (step S105 / NO). Therefore, as shown in FIG. 11, the process is performed again at step S10.
The process shifts to the processing of inputting the center lock / center unlock signal of 2.

As described above, in the near field communication unit 11, the rented vehicle 10 is in a state in which the center lock / center unlock information and the state transition instruction information are not received from the general management server 30, or the secret code from the near field communication transmitter 20. When the number or the lock / unlock instruction information has not been received, that is, in the normal standby state, step S102-
The processing loop of step S105 is repeatedly executed.

[Standby → Lending] Next, when the user permitted to lend operates the near field communication transmitter 20 near the lending vehicle 10 to transmit his / her own personal identification number to the lending vehicle 10,
The near field communication unit 11 determines that the personal identification number has been received (step S105 / YES), and the process shifts from the process loop of steps S102 to S105, which has been repeatedly executed until then, to step S106.

In step S106, the near field communication unit 11 transfers the personal identification number received by the near field data receiving means 11a to the ITS / CEV vehicle-mounted device 12 by the personal identification number transmitting means 11h. In addition, the password is the character memory 11
It is also stored in b (step S107).

In the ITS / CEV vehicle-mounted device 12, the personal identification number transferred from the near field communication unit 11 is used as the integrated management server 3
If it is determined that the password is the same as the personal identification number received from 0, the center unlock signal and the lending signal are returned to the near field communication unit 11. In the near field communication unit 11, I
After the password is transferred to the TS / CEV in-vehicle device 12, the reply is waited for a fixed time (step S108). The waiting time in step S108 is a value that can be set as appropriate, but for example, in the example of FIG. 1, it is possible to set it to about the communication time of the RS232C cable + α.

After waiting for a fixed time in step S108, the process proceeds to step S102 for inputting the center lock / center unlock signal. Here, since it is assumed that the center unlock signal and the lending signal are returned, in the center lock / center unlock signal input process of step S102, the center unlock signal is input in step S201 shown in FIG. It is determined that the signal input processing has been performed (step S201 / YES).

When it is determined in step S201 that the center unlock signal has been input (step S201 / YES), the proximity communication unit 11 then
The process proceeds to step S202 to execute the door unlock process. FIG. 13 shows the flow of the door unlock process in step S202 in detail. In this door unlock process, the proximity communication unit 11 sets the output signal of the IG lock / unlock signal output terminal to the “L” level by the IG lock / unlock signal transmitting means 11k. As a result, the solenoid driver 15 is instructed to unlock the IG lock state, and the ITS / CEV
The in-vehicle device 12 is notified that the IG lock state is unlocked (step S301). Upon receiving the IG lock state unlock instruction from the near field communication unit 11, the solenoid driver 15 energizes the IG cylinder lock solenoid 16 to unlock the IG lock state.

Next, in the door unlock process, the proximity communication unit 11 causes the door lock / door unlock signal transmitting means 11g to set the output signal of the door unlock signal output terminal to the "L" level for a certain period of time. As a result, the near field communication unit 11 gives an instruction to the door lock controller 13 to unlock the door lock state (step S302), and the door lock controller 13 having received this instruction keeps the door lock motor 14 for a certain period of time. Drive the door in the unlocking direction to unlock the door.

The processing for inputting the center lock / center unlock signal in step S102 this time is completed by the door unlock processing, and then step S in FIG.
The processing shifts to 103. In step S103, it is determined whether or not the vehicle state is rented out.
Since it is assumed that the lending vehicle 10 is in the lending state, it is determined here that the lending vehicle 10 is in the lending state (step S103 / YES).

In this way, when the vehicle state transitions from the standby state to the renting state, the processing of the near field communication unit 11 proceeds to step S109, and the processing during the renting state described below is executed.

[Renting] When the vehicle condition is renting out, the near field communication unit 11 first executes the process of inputting the center lock / center unlock signal in step S109. At this point, it is assumed that the center lock signal / center unlock signal or the like from the ITS / CEV vehicle-mounted device 12 or the proximity data from the proximity communication transmitter 20 is not received, that is, the normal lending state. Here, the process is directly transferred to step S110.

In step S110, it is determined whether or not the vehicle condition is renting. At this point, it is assumed that the rented vehicle 10 is in the renting state, and therefore the vehicle state is determined to be renting here (step S
(110 / YES), the process proceeds to step S111.

In step S111, the near field communication unit 11 starts the process of receiving the near field data from the near field communication transmitter 20. Then, it is determined whether proximity data has been received by the reception process (step S112). At this point, it is assumed that the rented vehicle 10 is in a normal renting state, so that it is determined in step S112 that proximity data has not been received (step S112).
/ NO), the processing is from step S112 to step S11.
Move to 9.

As described above, in the normal lending state, the near field communication unit 11 performs steps S109 to S1.
12 processing loops are repeatedly executed.

[Lending: Keyless lock when the vehicle is parked (proximity data = character strings 0 to 9 (personal identification number) + instruction code (L))] In the normal lending state, the near field communication unit 11 is operated as described above. Thus, the processing loop from step S109 to step S112 is repeatedly executed. Here, when the user parks the rented vehicle 10 and wants to lock the rented vehicle 10 from the outside when getting off the vehicle,
The personal identification number and the instruction code (“L” = lock) are transmitted to the rental vehicle 10 by using the near field communication transmitter 20.

The rental vehicle 10 has the proximity data receiving means 11a.
To receive proximity data. Then, in step S112, it is determined that the proximity data has been received (step S112).
/ YES), the near field communication unit 11 executes the processing loop executed in the normal lending state (step S10).
The process shifts from 9 to step S112) to step S113. Then, in step S113, it is determined whether or not the personal identification number in the proximity data received by the proximity data receiving means 11a and the personal identification number in the character memory 11b match, and authentication processing is performed for the user who has transmitted the proximity data. Be seen.

As a result of the authentication processing in step S113,
PIN and proximity data receiving means 1 in the character memory 11b
If the personal identification numbers received in 1a match and it is determined that the user is an authorized user (step S113 / YE
S) Next, the determination process for the instruction code in the proximity data is executed.

First, in this judgment processing, it is judged whether or not the instruction code in the proximity data is "L" (step S114). Here, since it is assumed that the instruction code in the proximity data is "L", the instruction code in the proximity data is determined to be "L" (step S11).
4 / YES). Therefore, the process shifts to the door lock process of step S115.

FIG. 14 is a flow chart showing in detail the flow of the door lock process. As shown in FIG. 14, in the door lock process, first, it is determined whether or not the prerequisites for the door lock operation (the door is closed and the IG key cylinder is at the “LOCK” position) are satisfied by the prerequisite checker 11d. It is determined whether or not (step S401). If it is determined in this determination that the prerequisites for the door lock operation are satisfied (step S401 / YES), then the IG
The lock / unlock signal transmitting means 11k sets the output signal of the IG lock signal output terminal to the "H" level, and the ITS
/ CEV in-vehicle device 12 is notified that the IG lock state is locked, and solenoid driver 15
Is given to the IG lock state. As a result, the solenoid driver 15 deenergizes the IG key cylinder lock solenoid 17 to lock the IG lock state (step S402).

To migrate. In the door lock process, as shown in FIG. 14, it is first determined whether or not the preconditions for the door lock process are satisfied (step S4).
01). In this way, since the preconditions are checked before the door lock process, when the vehicle is traveling, that is, when the IG key cylinder 17 is in a position other than "LOCK", the IG lock state is caused by an operation error on the side of the integrated management center. Can be prevented from being locked.

If the preconditions for the door lock process are satisfied (step S401 / YES), the output signal of the IG lock / unlock signal output terminal is set to the "H" level, and the ITS / CEV vehicle-mounted device 12 is notified. On the other hand, it notifies that the IG lock state is locked, and gives the solenoid driver 15 an instruction to lock the IG lock state (step S402). Solenoid driver 15

As described above, by the proximity communication unit 11 executing the above processing steps, the general management center can lock the IG lock state and the door lock state of the rental vehicle 10 in the standby state. In this case, the center lock / center unlock signal input processing in step S109 is completed by the door lock processing.
The processing loop of steps S109 to S112 in the normal lending state is repeatedly executed.

[Remote Operation from Central Management Center: Center Unlocked (Lending)] In addition, the general management center, when the vehicle is in the lending state, that is, the proximity communication unit 1
When 1 repeatedly executes the processing loop of steps S109 to S112, the door lock state and the IG lock state of the rental vehicle 10 can be unlocked. In this case, the comprehensive management server 30 transmits the center unlock instruction information.

This center unlock instruction information is ITS /
When the ITS / CEV in-vehicle device 12 receives the center unlock instruction information received by the instruction information receiving means 12i of the CEV in-vehicle device 12, the center lock / center unlock signal transmitting means 12j is used to output the center unlock signal output terminal. The output signal is set to "L" level.

Accordingly, in the center lock / center unlock input process of step S109, it is determined that the center unlock signal is input in step S203 of FIG. 12 (step S203 / YES), and the process proceeds to the door unlock process of step S204. And processing is transferred. In the door unlock process, as shown in FIG. 13, first, the IG lock /
The output signal of the unlock signal output terminal is set to the “L” level to notify the ITS / CEV vehicle-mounted device 12 that the IG lock state is unlocked, and the solenoid driver 15 is unlocked. An instruction to lock is given (step S301). When the solenoid driver 15 receives this instruction, the IG key cylinder lock solenoid 16 is energized to unlock the IG lock state.

Next, the near field communication unit 11 sets the output signal of the door unlock signal output terminal to the "L" level for a certain period of time, and gives the door lock controller 13 an instruction to unlock the door lock state (step S302). .
Upon receipt of this instruction, the door lock controller 13 drives the door lock motor 14 in the unlock direction for a certain period of time to unlock the door lock state.

As described above, by the proximity communication unit 11 executing the above processing steps, the general management center can unlock the IG lock state and the door lock state of the lending vehicle 10 during the lending state. In this case, the center lock / center unlock signal input processing in step S109 is completed by the door unlock processing, and thereafter, step S1 in the normal standby state is performed.
The processing loop from 09 to step S112 is repeatedly executed.

[Transfer of incorrect PIN from near field communication transmitter 20 (standby)] When the rented vehicle 10 is in a normal standby state, as described above, steps S102 to S
The processing loop 105 is repeatedly executed. At this time, for example, assume that character data different from the personal identification number of the authorized user of the rental vehicle 10 is transferred from the near field communication transmitter 20. When the proximity data receiving means 11a receives the character data, it is determined in step S105 that the proximity data has been received (step S105 / YE).
S). As a result, the processing shifts from the processing loop of steps S102 to S105 to step S106.

In step S106, the near field communication unit 11 transmits the personal identification number (character data) received this time to the ITS / CEV vehicle-mounted device 12 by the personal identification number transmission means 11h (step S107). ITS / CEV in-vehicle device 1
In 2, the personal identification number receiving unit 12b receives the personal identification number, and it is determined whether the personal identification number matches the personal identification number of the authorized user received from the comprehensive management server 30. Here, since it is assumed that the personal identification number in the proximity data received this time by the personal identification number receiving means 12b is different from the personal identification number of the authorized user, the center lock / center unlock signal transmitting means 12j. , Lending signal transmission means 12
The center unlock signal and the lending signal are not output from h.

Therefore, in the subsequent center lock / center unlock input process in step S102, the door unlock process is not executed, and step S10 is performed as it is.
Since there is no lending signal input in step S103, the processing loop of steps S102 to S105 in the normal waiting state is repeatedly executed.

As described above, when an incorrect personal identification number is transferred while the vehicle is in the waiting state, the near field communication unit 11 executes the normal processing loop in the waiting state, and the door lock state is set. And the IG lock state is not unlocked. Therefore, the user who has sent the wrong personal identification number cannot enter the vehicle, and even if he / she can enter the vehicle, the solenoid lock and the steering lock are locked, so the vehicle cannot be driven and the steering wheel cannot be turned. .

In step S107, the incorrect personal identification number is stored in the character memory 11b, but since the personal identification number cannot use the rental vehicle 10 as described above, the personal identification number in the character memory 11b. The personal identification number stored in is never used. That is, the character data in the character memory 11b is overwritten until the personal identification number of the authorized user is received.

[Transfer of incorrect PIN from near field communication transmitter 20 (during lending)] When the lending vehicle 10 is in a normal lending state, as described above, steps S109 to S
The processing loop 112 is repeatedly executed. At this time, it is assumed that the proximity data is transferred from the proximity communication transmitter 20. When the proximity data receiving unit 11a receives the proximity data, it is determined in step S112 that the proximity data has been received (step S112 / YES).
As a result, the processing shifts from the processing loop of steps S109 to S112 to step S113, and it is verified whether or not the personal identification number received this time by the proximity data receiving means 11a matches the personal identification number stored in the character memory 11b. It is judged by the means 11c (step S11)
3).

Since it is assumed here that the character data different from the personal identification number of the authorized user is received, the received personal identification number is stored in the character memory 11 in step S113.
It is determined that the password does not match the password in b (step S113 / NO). In that case, the near field communication unit 11 transmits the personal identification number (character data) received this time to the ITS / CEV vehicle-mounted device 12 by the personal identification number transmission means 11h (step S118).

In the ITS / CEV in-vehicle device 12, the personal identification number receiving means 12b receives the personal identification number, and it is determined whether or not it coincides with the personal identification number of the authorized user received from the comprehensive management server 30. Since the personal identification number received this time by the personal identification number receiving means 12b is not the personal identification number of the authorized user, the center unlock / center unlock signal transmitting means 12j and the lending signal transmitting means 12h output the center unlock signal and the lending signal. Is not output.

Therefore, in the center lock / center unlock input process in the subsequent step S109, the door unlock process is not executed, and the process is directly performed in step S11.
The determination process of 0 is performed. Further, since the vehicle state is currently in the lending state, the process proceeds to step S111, and thereafter, the processing loop of steps S109 to S112 in the normal lending state is repeatedly executed.

As described above, when the wrong personal identification number is transferred when the vehicle is in the lending state, the near field communication unit 11 executes the processing loop in the normal lending state, and the door lock state is set. And the IG lock state is not unlocked. Therefore, the user who has sent the wrong personal identification number cannot enter the vehicle, and even if he / she can enter the vehicle, the solenoid lock and the steering lock are locked, so that the vehicle cannot be driven and the steering wheel cannot be moved. .

<Operation of ITS / CEV On-Board Machine 12> Next, the operation of the ITS / CEV on-board machine 12 of this embodiment will be described in detail. The ITS / CEV in-vehicle device 12 of this embodiment independently receives the center lock / center unlock instruction information and the state transition instruction information from the integrated management center. As already explained, ITS / CEV
The in-vehicle device 12 is locked from the central management server 30
When the center unlock instruction information is received, the center lock signal / center unlock signal is transmitted to the near field communication unit 11 to lock / lock the door lock state and the IG lock state.
It controls to unlock. Also, ITS / C
When the EV vehicle-mounted device 12 receives the vehicle state transition instruction information from the comprehensive management server 30, the EV vehicle-mounted device 12 controls the EV controller to prohibit / permit the generation of the activation signal.

As described above, the ITS / CEV vehicle-mounted device 12
Receives independently the center lock / center unlock instruction information and the state transition instruction information from the integrated management center, and independently controls the center lock / center unlock operation and the vehicle state transition operation.

[Center Lock / Center Unlock (1)] First, the operation when the ITS / CEV vehicle-mounted device 12 receives the center lock / center unlock instruction information from the general management server 30 will be described. Figure 15 shows IT
7 is a flowchart showing a flow of a center lock / center unlock control operation executed by the S / CEV in-vehicle device 12. The ITS / CEV in-vehicle device 12 executes the processing shown in FIG. 15 to execute the center lock / center unlock operation based on the instruction from the general management center.

The ITS / CEV vehicle-mounted device 12 executes step S
In 501, the instruction information receiving means 12 receives the center lock / center unlock instruction information from the comprehensive management server 30.
It is always judged at a predetermined timing whether or not it is received by i. When it is determined that the center lock / center unlock instruction information is received by the instruction information receiving unit 12i from the comprehensive management server 30 and the center lock / center unlock instruction information is received in step S501 (step S50).
1 / YES), the ITS / CEV vehicle-mounted device 12 outputs the center lock signal / center unlock signal to the near field communication unit 11 by the center lock signal / center unlock signal transmission means 12j (step S502).

Upon receiving the center lock / center unlock instruction information, the near field communication unit 11 performs control for locking / unlocking the door lock state and the IG lock state. The ITS / CEV in-vehicle device 12 monitors these control results by the change (potential change) of the input signal in the IG lock state monitoring means 12g and the door lock state monitoring means 12f. First, the ITS / CEV in-vehicle device 12
It is determined whether or not there is a change in the IG lock / unlock signal input by the G lock state monitoring means 12g (step S503).

For example, when the potential of the IG lock / unlock signal changes from "H" level to "L" level,
The ITS / CEV in-vehicle device 12 detects a change in the IG lock / unlock signal and determines that the IG lock state has changed from locked to unlocked. When the potential of the IG lock / unlock signal changes from the “L” level to the “H” level, the ITS / CEV in-vehicle device 12 also detects the change in step S503, and the IG lock state is unlocked. It is determined that the lock has been set (step S5).
03 / YES).

As described above, the ITS / CEV vehicle-mounted device 12
When the change in the IG lock state is detected from the change in the potential of the IG lock / unlock signal, the change content is
The lock state information is transmitted from the vehicle state information transmitting means 12k to the general management server 30 (step S504).

Next, the ITS / CEV vehicle-mounted device 12 determines whether or not there is a change (potential change) in the door lock / unlock signal input by the door lock state monitoring means 12f (step S505). When there is a potential change in the door lock / unlock signal in step S505, for example, when the potential of the door lock / unlock signal changes from the “H” level to the “L” level, the ITS / CEV vehicle-mounted device 12 Then, the change in the door lock / unlock signal is detected, and it is determined that the door lock state is changed from locked to unlocked (step S505 / YES). When the potential of the door lock / unlock signal changes from the “L” level to the “H” level, the ITS / CEV in-vehicle device 12 also detects the change in step S505,
It is determined that the door lock state has changed from unlocked to locked.

As described above, the ITS / CEV vehicle-mounted device 12
When the change in the door lock state is detected from the change in the potential of the door lock / unlock signal, the change state is transmitted from the vehicle state information transmitting means 12k to the general management server 30 as the door lock state information (step S506). .
In the present embodiment, as described above, the change in the IG lock / unlock signal is detected earlier than the change in the door lock / door unlock signal, but this order may be changed. That is, steps S503 and S50
4 and steps S505 and S506 are in no particular order.

[Center Lock / Center Unlock (Part 2)] Further, the ITS / CEV vehicle-mounted device 12 can be operated even when the personal identification number is transferred from the near field communication unit 11.
Depending on the state of the lending vehicle 10 at that time, the center unlock / center unlock signal transmitting means 12j and the lending signal transmitting means 12h output the center unlock signal and the lending signal to the near field communication unit 11.

Next, the operation when the ITS / CEV vehicle-mounted device 12 inputs the personal identification number from the near field communication unit 11 will be described. FIG. 16 is a flowchart showing the flow of the second center lock / center unlock control operation executed by the ITS / CEV vehicle-mounted device 12. This control operation is performed when the secret code different from the secret code in the character memory 11b of the close proximity communication unit 11 is transferred from the close proximity communication transmitter 20 and the authenticating means 11c of the close proximity communication unit 11 does not authenticate the authorized user. , Proximity communication unit 1
This is executed for the personal identification number transferred from 1.

The first aspect in which such a situation may occur is at the start of use as already described. In this case, since no character data is stored in the character memory 11b, authentication as an authorized user cannot be obtained by the authentication means 11c, and the personal identification number is sent by the personal identification number transmission means 11h.
It is transferred to the TS / CEV in-vehicle device 12.

A second aspect is a case where a secret code different from the secret code stored in the character memory 11b is transferred from the near field communication transmitter 20 during use. In this case, the authentication means 1 of the near field communication unit 11
In 1c, authentication as an authorized user cannot be obtained, and the personal identification number transmission means 11h transfers the personal identification number to the ITS / CEV vehicle-mounted device 12. At this time, the ITS / CEV in-vehicle device 1
In 2, it is judged whether or not the personal identification number of the authorized user received from the comprehensive management server 30 and the personal identification number transferred from the near field communication unit 11 match, and the authentication processing is executed for the personal identification number.

To carry out the authentication process of the authorized user in the near field communication unit 11, it is appropriate that the near field communication unit 11 which directly receives the personal identification number from the near field communication transmitter 20 is allowed to perform the authentication process. ITS / CEV in-vehicle device 1
There is an advantage that the load of 2 is reduced. However, the wrong personal identification number may be transferred from another person, and the recorded contents of the character memory 11b may be updated to the personal identification number. Therefore, in the case where the near field communication unit 11 is not authenticated. , ITS / CEV vehicle-mounted device 12 is configured to entrust the final judgment.

Therefore, even when the character data in the character memory 11b is updated to an incorrect personal identification number while taking advantage of the fact that the near field communication unit 11 has the authentication processing function,
The authorized user can unlock the rental vehicle 10 and can use the rental vehicle 10 without any problem.

As shown in FIG. 16, in step S601, the ITS / CEV vehicle-mounted device 12 always determines at a predetermined timing whether or not the personal identification number from the near field communication unit 11 is received by the personal identification number receiving means 12b. ing. When the personal identification number is received from the near field communication unit 11, step S
When it is determined in 601 that the personal identification number has been received (step S601 / YES), the ITS / CEV in-vehicle device 12 receives the personal identification number received from the comprehensive management server 30 and the personal identification number transferred from the near field communication unit 11. Are compared with each other, and an authentication process for the transferred personal identification number is executed (step S602).

If both personal identification numbers match in step S602 and authentication as an authorized user is obtained (step S602 / NO), then whether a usage permission instruction has already been received from the general management server 30. It is determined whether or not (step S603). In this determination, if it is determined that the usage permission instruction has already been received (step S603 / YE
S), the center lock signal / center unlock signal transmitting means 12j outputs the center lock signal / center unlock signal to the near field communication unit 11 (step S60).
4).

Upon receiving the center lock / center unlock instruction information, the near field communication unit 11 performs control for locking / unlocking the door lock state and the IG lock state. The ITS / CEV vehicle-mounted device 12 monitors these control results by the change (potential change) of the input signal in the IG lock state monitoring means 12g and the door lock state monitoring means 12f. First, the ITS / CEV in-vehicle device 12 determines whether or not there is a change in the IG lock / unlock signal input by the IG lock state monitoring means 12g (step S60).
5).

For example, when the potential of the IG lock / unlock signal changes from "H" level to "L" level,
The ITS / CEV in-vehicle device 12 detects a change in the IG lock / unlock signal and determines that the IG lock state has changed from locked to unlocked. When the potential of the IG lock / unlock signal changes from the “L” level to the “H” level, the ITS / CEV in-vehicle device 12 also detects the change in step S605 and the IG lock state is unlocked. It is determined that the lock has been set from step S6 (step S6).
05 / YES).

As described above, the ITS / CEV vehicle-mounted device 12
When the change in the IG lock state is detected from the change in the potential of the IG lock / unlock signal, the change content is

Can be controlled to be changed appropriately. Further, at that time, the comprehensive management server 30 is configured to automatically transmit the center lock / center unlock instruction information, the state transition instruction information, and the like according to the monitoring information based on a program stored in advance. You can also

For example, the center lock instruction information may be transmitted after a predetermined time has elapsed after the vehicle state is changed from the rented state to the standby state (after the state transition instruction information is transmitted). . In addition, if the door lock state and the IG lock state are locked for a certain period of time during lending, vehicle state instruction information that causes the vehicle state to transition from lending to waiting is transmitted and the generation of a start signal is prohibited. Or the position of the IG key cylinder 17 is at “ROCK”, but if the IG lock state is not locked for a certain period of time, the center lock instruction information is automatically transmitted and the IG
The locked state can be locked.

As described above, the integrated management center manually transmits the center lock / center lock instruction information, the state transition instruction information, etc. from the integrated management server 30, or the integrated management server 30 automatically sends the center lock / center lock instruction information. The crime prevention system can be further strengthened by transmitting unlock instruction information, state transition instruction information, and the like.
