Below, with reference to a figure, the door control system in each Example is demonstrated.
<First Example>
With reference to FIG. 1 and FIG. 2, the door control system 100 in a present Example is demonstrated. The door control system 100 includes a control device 10 provided in the vehicle C, and a portable device 20 that is carried by the user of the vehicle C and communicates with the control device 10. The control device 10 transmits a response request signal for requesting a response to the portable device 20, and the portable device 20 returns a response signal in response to the response request signal. And in the door control system 100, the control apparatus 10 controls only the unlocking of the door D of the vehicle C, or both unlocking and opening by the response signal which the portable device 20 returned. Further, the control device 10 may control only the unlocking of the door D of the vehicle C or both unlocking and opening by the response signal returned from the portable device 20. The door D will be described as a power slide door (hereinafter referred to as PSD) in this specification. The PSD is a door that is provided mainly on the side of the vehicle C and opens and closes by sliding electrically. To open the PSD means to slide the closed PSD to the open state.

  The portable device 20 receives an operation unit 25 that receives a user's operation, and when the operation unit 25 is operated, a reservation signal that unlocks the door D and / or makes a reservation for opening the door to the control device 10. A portable device UHF transmitting unit 22 for transmitting, a portable device UHF receiving unit 211 for receiving a reservation acceptance signal from the control device 10, a portable device LF receiving unit 212 for receiving a response request signal from the control device 10, and a portable device A portable device storage unit 24 that stores information received by the UHF reception unit 211, a notification unit 26 that notifies the user, and a portable device control unit 23 that controls them.

  The operation unit 25 is a button provided on the portable device 20, for example, which is operated when the user makes a reservation for unlocking and / or opening the door D. The user operates the operation unit 25 when going to the vehicle C, and makes a reservation to unlock and / or open the door D without any operation when approaching the vehicle C. When the operation unit 25 is pressed, the portable device control unit 23 detects it and causes the portable device UHF transmission unit 22 to transmit as follows.

  When the operation unit 25 is operated, the portable device UHF transmission unit 22 transmits a radio wave in the UHF band including a reservation signal for unlocking the door D and / or making a reservation for opening the door to the control device 10. . A UHF band radio wave including a reservation signal can generally reach farther than a LF band radio wave, which will be described later. Therefore, even if the user is relatively far away from the vehicle C, the user can reserve the unlocking and / or opening of the door D by operating the operation unit 25. In addition, when the portable device LF receiving unit 212 receives the response request signal in the LF band from the control device 10, the portable device UHF transmission unit 22 transmits a response signal for the response request signal using a radio wave in the UHF band. When a response request signal in the LF band with a short reach is received, the response signal can be accurately delivered to the control device 10 by transmitting a response signal in the UHF band with a long reach. The portable device UHF receiving unit 211 receives a reservation acceptance signal transmitted by the control device 10 in the UHF band, as will be described later.

  In response to a reservation signal indicating that the door D transmitted by the portable device UHF transmission unit 22 is unlocked and / or reserved for opening the door, the portable device UHF reception unit 211 receives from the control device 10. Information on the received reservation acceptance signal, that is, information indicating that the reservation is accepted and permitted is stored. The portable device storage unit 24 may be a temporary storage area in the portable device control unit 23 configured by a microcomputer, or may be provided in a permanent memory. When the portable device UHF receiving unit 211 receives the reservation acceptance signal, the notification unit 26 notifies the user that the user is permitted. The method of notifying by the notification unit 26 may be any of visual, auditory, tactile, or a combination thereof. For example, when visual notification is performed, a light emitting diode may be provided and light may be emitted in a predetermined pattern. When making an audible notification, a buzzer may be provided to sound in a predetermined pattern. When tactile notification is performed, a vibration motor may be provided to vibrate in a predetermined pattern.

  The control device 10 includes a control device UHF reception unit 11 that receives a reservation signal and a response signal from the portable device 20, a control device UHF transmission unit 121 that transmits a reservation acceptance signal, and a control device LF transmission unit that transmits a response request signal. 122, a reservation processing unit 15 that performs a reservation process based on a reservation signal from the portable device 20, a reservation signal monitoring unit 16 that monitors a reception state of the reservation signal, and a reception state of a reservation signal that is monitored by the reservation signal monitoring unit 16 Includes a determination unit 17 that determines whether or not a predetermined condition is satisfied, and a control device control unit 13 that controls the unlocking and / or opening of the door D. When receiving the reservation signal transmitted from the portable device 20 when the operation unit 25 is operated, the control device UHF receiving unit 11 transmits the reservation signal to the reservation signal monitoring unit 16 and the control device control unit 13. The reservation signal monitoring unit 16 that has received the reception of the reservation signal monitors the reception status of the reservation signal, such as whether a plurality of reservation signals are received within a predetermined time. The control device control unit 13 that has received the reception of the reservation signal causes the reservation processing unit 15 to perform a reservation process, causes the control device UHF transmission unit 121 to transmit a reservation acceptance signal, and also controls the control device LF transmission unit 122. Then, the control device LF transmitter 122 continues to transmit the response request signal at predetermined intervals for a predetermined period. The determination unit 17 determines whether or not the reception status of the reservation signal monitored by the reservation signal monitoring unit 16 satisfies a predetermined condition such as whether the reservation signal is a predetermined number of times or less within a predetermined time. If the above condition is satisfied, the reservation processing unit 15 does not perform the reservation process and does not start the transmission of the response request signal.

  Since the response request signal is transmitted by the LF band radio wave by the control device LF transmitter 122, it does not reach farther than the UHF band radio wave. The LF band has a long wavelength, and in the distance order near the vehicle C, the radiation intensity decreases more rapidly (in inverse proportion to the cube of the distance) than the UHF band. Accordingly, the response request signal reaches the portable device 20 inside the reachable ranges A1, A2, and A3 as shown in FIG. 2, but does not reach the portable device 20 'outside the reachable range. In this figure, three LF transmitters 122A, 122B, 122C are provided near the right door, the left door, and the rear door, respectively, and response request signals transmitted from these three LF transmitters 122A, 122B, 122C. The ranges A1, A2, and A3 that are reached are respectively shown. On the other hand, the reservation signal is transmitted by the portable device UHF transmission unit 22 and the reservation acceptance signal is transmitted by the UHF band radio wave by the control device UHF transmission unit 121. Communication is possible between the portable device 20 ′ located far away from the vehicle C and the vehicle C.

  Then, the reservation acceptance signal transmitted in response to the reservation signal from the control device 10 is received by the portable device 20 ′, but the response request signal started to be transmitted at almost the same time is sent to the portable device 20 ′. It will not be received. When the portable device UHF reception unit 211 receives the reservation acceptance signal, the portable device storage unit 24 receives information indicating that the reservation is accepted by the control device 10 and the reservation is permitted (permitted). Remember. Then, the notification unit 26 notifies the user that the door D is permitted to be unlocked and / or opened when the user approaches the vehicle C. The operation unit 25 is configured to always accept a reservation operation, and can perform a reservation operation a plurality of times. Details will be described later. The operation unit 25 may be configured to accept a reservation cancel operation. In this case, the user who has received the notification may cancel the reservation by a cancel operation.

  A user who knows that the door D is allowed to be unlocked and / or opened when approaching the vehicle C gradually reaches the vehicle C, that is, a range A1, A2, A3 in which the response request signal reaches. Coming closer. After the control device LF transmitter 122 starts transmitting the response request signal, it continues to transmit the response request signal at a predetermined interval for a predetermined period. Accordingly, the user enters the range A1, A2, A3 within which the response request signal reaches within a predetermined time during which the response request signal is continuously transmitted, and the portable device LF receiving unit 212 receives the response request signal. In this case, the portable device UHF transmitter 22 automatically returns a response signal without any user operation. When returning the response signal, the portable device UHF transmission unit 22 transmits a response signal including information indicating that permission has been obtained by receiving the reservation acceptance signal.

  The control device control unit 13 includes a microcomputer, and is connected to a door opening / closing device OC that drives the door D, a welcome light WL, an engine switch E, a power supply device P, and the like. Then, the control device control unit 13 controls the control device UHF reception unit 11, the control device UHF transmission unit 121, and the control device LF transmission unit 122, and receives the response signal transmitted from the portable device 20 to thereby detect the vehicle C. Control unlocking and / or opening of door D. That is, when the control device UHF receiving unit 11 receives a response signal including information indicating that the response is permitted, the control device control unit 13 issues a command to the door opening / closing device OC, and releases the door D. Lock and / or open doors. When the door D is unlocked / opened when a response signal including information indicating permission is received as well as the response signal, it can be distinguished from the portable device 20 that has not made a reservation. That is, if a reservation is not made and a reservation acceptance signal is not received, even if the vehicle C approaches the vehicle C, a response signal including information indicating that it has been permitted cannot be transmitted. Do not unlock / open D. Accordingly, it is possible to prevent the door D from being inadvertently opened even when the portable device 20 that has not made a reservation approaches.

  In addition, the control device control unit 13 may instruct the welcome light WL to light up so as to open the door or the like, or may instruct the power supply device P or the engine switch E to turn on the vehicle C. And start the engine. Thus, when the user makes a reservation for unlocking / opening the door D of the vehicle C, when the user approaches the vehicle C, the door D is unlocked / opened without operating the portable device 20 or the like. As a result, the door control system 100 with improved user convenience can be provided.

  Note that the operation unit 25 of the portable device 20 may be configured to select whether to reserve the opening of the right door D of the vehicle C or the opening of the left door D or the like. Good. In this case, when the user approaches the vehicle C, only the selected door D can be opened without operating the portable device 20 or the like. According to this, it is possible to provide the door control system 100 that improves the convenience for the user and improves the safety so that the other door D does not open carelessly.

  The control device 10 may further include a control device storage unit 14 that stores the identification number of the portable device 20. In this case, when transmitting the reservation signal and the response signal, the portable device UHF transmission unit 22 transmits the reservation signal and the response signal including the identification number of the portable device 20. When the user operates the operation unit 25 of the portable device 20 and the control device UHF reception unit 11 receives a reservation signal including the identification number of the portable device 20, the control device storage unit 14 stores the identification number. Then, the control device LF transmission unit 122 starts transmission of the response request signal. The control device UHF reception unit 11 includes a response signal including information indicating that the response request signal is permitted and the identification number of the portable device 20. Is received, the control device control unit 13 compares the identification number included in the response signal with the identification number previously stored in the control device storage unit, and only if the two match, Lock and / or open doors. In this way, the door D is unlocked and / or opened only when the approaching portable device 20 is the same as the reserved portable device 20, thereby improving crime prevention and avoiding malfunctions. Can do.

  When the control device UHF transmission unit 121 transmits a reservation acceptance signal, the control device storage unit 14 may store information indicating that the reservation from the portable device 20 has been accepted. In this case, when the user subsequently approaches the vehicle C and the control device UHF reception unit 11 receives a response signal including information indicating that the response corresponding to the response request signal is permitted, the control device control unit 13 performs control. It is inspected whether or not the information indicating the permission is stored in the device storage unit 14. Then, only when the information indicating permission is stored, the door D is unlocked and / or opened, and when the door D is unlocked and / or opened, the control device storage unit 14 deletes information indicating permission. In this way, when a response signal including information indicating permission is received from the portable device 20, the door D is unlocked only when information indicating permission is stored on the control device 10 side. Further, crime prevention can be further improved by opening the door.

  With reference to FIG. 3 and FIG. 4, the control apparatus 10 of the door control system 100 and the control method of the portable device 20 are demonstrated. Note that S means a step. In S100, the control device 10 waits for reception of a reservation signal from the portable device 20. The portable device 20 always accepts a reservation operation by the operation unit 25, and in S200, checks whether or not a reservation operation for opening the PSD is performed by the operation unit 25. In the portable device 20, the portable device LF reception unit 212 checks whether or not the response request signal from the control device 10 has been received in S214 when the reservation operation is not performed. When the response request signal is not received, the process returns to S200, and the loop of S200 and S214 is repeated until there is a reservation operation or the response request signal is received.

  When a reservation operation is performed, the portable device storage unit 24 stores reservation information such as that the reservation has been made and which door of the vehicle C has been reserved to be unlocked / opened in S202. . In S204, the portable device UHF transmission unit 22 of the portable device 20 transmits a reservation signal for performing reservation for unlocking / opening the PSD together with the reservation information and its own identification number to the control device 10, and the portable device control unit 23 waits for a predetermined time in S206. That is, when the predetermined time has elapsed, the portable device control unit 23 does not perform the following process. When the predetermined time has not elapsed, the portable device UHF reception unit 211 has received a reservation acceptance signal in S208. Check for no.

  When the control device UHF reception unit 11 of the control device 10 receives the reservation signal or the like transmitted by the portable device UHF transmission unit 22 in S100, the reservation signal monitoring unit 16 determines whether or not the reservation prohibition flag is off in S102. inspect. The reservation prohibition flag is a flag managed by the reservation signal monitoring unit 16, and the initial value is off. Since the reservation prohibition flag is off now, the reservation processing unit 15 performs a series of reservation processing operations. That is, the control device storage unit 14 stores the reservation information included in the reservation signal and the identification number of the portable device 20 in S104. In S106, the control device control unit 13 detects the position of the door for which the unlocking / opening door reservation is made in the reservation information (the direction in which the user approaches the vehicle as viewed from the vehicle). In S108, the control device control unit 13 sets the direction in which the response request signal is transmitted based on the reserved door position. In S110, control device UHF transmission unit 121 transmits information indicating that PSD unlocking / opening is permitted to portable device 20 as a reservation acceptance signal. It should be noted that the information indicating that permission has been granted may be identified as different information each time using a rolling code or the like. In S112, the reservation signal monitoring unit 16 sets a predetermined time (T1) in which the current reservation is valid.

  In S114, the control device control unit 13 checks whether or not a predetermined time (T1) has elapsed. If the predetermined time (T1) has elapsed, it is determined that the reservation has become invalid, and the processing described below is not performed. The reservation information stored in the control device storage unit 14 is cleared. If the predetermined time (T1) has not yet elapsed, the control device LF transmission unit 122 starts transmission of a response request signal in S116 and continues the transmission at a predetermined time (T1) at a predetermined interval. .

  In the portable device 20 waiting for reception of the reservation acceptance signal in S206 and S208, the portable device UHF receiving unit 211 receives the reservation acceptance signal transmitted by the control device UHF transmission unit 121 in S110, and then stores the portable device storage unit. 24 is stored in S210 as a reservation permission signal indicating that the reservation is permitted. In S212, the notification unit 26 notifies the user that the reservation of the unlocking / opening of the PSD is permitted by the control device 10. When the reservation acceptance signal is not received, the portable device UHF reception unit 211 checks whether or not a reservation rejection signal described later is received in S218. When receiving the reservation disapproval signal, the notification unit 26 notifies the user that the reservation of the unlocking / opening of the PSD is not permitted by the control device 10 in S220. When the reservation non-permission signal has not been received, the process returns to S206, and the loop of S208 and S218 is repeated until a predetermined time elapses or a reservation acceptance signal or reservation non-permission signal is received.

  The user who knows that the reservation for opening the PSD is permitted approaches the vehicle C together with the portable device 20. When making a reservation, the response request signal did not reach the portable device 20, but when the user approaches the vehicle C, the response request signal enters the range where the response request signal reaches. When the portable device LF reception unit 212 receives the response request signal from the control device 10, the portable device UHF transmission unit 22 stores the response signal including its own identification number in response to the response request signal in S216. It is transmitted to the control device 10 together with the information indicating that the permission is stored in the unit 24.

  In S118, the control device UHF reception unit 11 checks whether or not the response signal from the portable device 20 for the response request signal transmitted by the control device LF transmission unit 122 in S116 has been received. When the control device UHF receiving unit 11 receives the response signal, the control device control unit 13 authenticates the portable device 20 based on the response signal in S120. Specifically, the control device control unit 13 identifies the identification number of the portable device 20 included in the response signal as the identification number stored in the control device storage unit 14 as the reserved portable device 20 (S104). To see if it matches. Further, the control device control unit 13 determines whether or not the information indicating that the permission is included in the response signal matches the information indicating that the permission is generated and stored in the control device storage unit 14 (S110). Confirm.

  In S122, the control device control unit 13 checks whether or not a match can be confirmed. When the control device control unit 13 confirms the match, the control device control unit 13 performs control to unlock / open the PSD in S124. If the PSD is unlocked / opened, the control device control unit 13 clears the information indicating that the permission is stored in the control device storage unit 14 in S126. If authentication has failed, the process returns to S114 to check whether or not a predetermined time (T1) has elapsed. If not, a response request signal is transmitted in S116, and this is continued. .

  When the control device UHF reception unit 11 does not receive the response signal, the control device UHF reception unit 11 checks whether or not the reservation signal from the portable device 20 has been received again in S130. That is, the operation unit 25 of the portable device 20 is configured to always accept a reservation operation, and can perform a reservation operation a plurality of times. Therefore, in addition to the reservation signal received in S100, the operation signal is received again. Inspect whether or not. If not, the process returns to S114 to check whether or not a predetermined time (T1) has elapsed. If not, the response request signal is transmitted in S116, and the predetermined time (T1) is transmitted. Until the time elapses, the response signal is received, or the reservation signal is received, the loop of S114, S116, S118, and S130 is repeated.

  When the reservation signal is received, the reservation signal monitoring unit 16 counts the number of receptions of the reservation signal, that is, the number of reservation operations in S132. In S134, the determination unit 17 determines whether or not the number of reservation operations within a predetermined time (T1) is within a predetermined number. If it is within the predetermined number of times, the process returns to S104 to perform a series of reservation processing operations. That is, when the control device UHF receiving unit 11 receives the reservation signal again before receiving the response signal corresponding to the response request signal, the determination unit 17 does not satisfy the predetermined condition of the reception status of the reservation signal ( When it is determined that the number of times of reception of the reservation signal does not exceed the predetermined number), the reservation processing unit 15 performs the reservation processing, and the control device LF transmission unit 122 continues to transmit the response request signal. As described above, when the reception status of the reservation signal does not satisfy the predetermined condition, the reservation process is performed, so that the intention of the user can be reflected and the consumption of the battery of the vehicle can be suppressed. If it is within the predetermined number of times, after returning to S104 and performing a series of reservation processing operations, until a predetermined time (T1) elapses, a response signal is received, or a reservation signal is received, The loop of S114, S116, S118, and S130 is repeated.

  When the number of reservation operations exceeds the predetermined number, the control device control unit 13 turns on the reservation prohibition flag in S136. Then, the control device UHF transmission unit 121 transmits a reservation non-permission signal in S138. Thereafter, in S126, the control device control unit 13 clears the stored information and cancels the reservation made by the reservation processing operation. When the portable device 20 receives the reservation disapproval signal, as described above, the notification unit 26 notifies the user that the reservation of the unlocking / opening of the PSD is not permitted by the control device 10. In this state, when a reservation operation is performed again at the operation unit 25, the control device 10 waits for reception of a reservation signal from the portable device 20 in S100, so whether or not the reservation prohibition flag is off in S102. Inspect. Since the reservation prohibition flag is turned on this time, a reservation non-permission signal is transmitted in S128, and a series of reservation processing operations are not performed. Therefore, when the number of reservation operations exceeds the predetermined number, the reservation itself is canceled and the reservation is not accepted again until the reservation prohibition flag is reset. The reservation prohibition flag is reset after a relatively long time has elapsed.

  As described above, when the control device UHF reception unit 11 receives the reservation signal transmitted from the portable device UHF transmission unit 22, the reservation processing unit 15 performs the reservation process, and the control device LF transmission unit 122 transmits the response request signal. When the portable device LF receiver 212 receives the response request signal after the control device LF transmitter 122 starts transmitting the response request signal, the portable device UHF transmitter 22 transmits the response signal. When the control device UHF receiving unit 11 receives a response signal corresponding to the response request signal, the control device control unit 13 unlocks and / or opens the door, and the control device UHF receiving unit 11 receives the response request signal. If the reservation signal is received again before receiving the corresponding response signal, and the determination unit 17 determines that the reception status of the reservation signal satisfies a predetermined condition, the control device LF transmission unit 22, it stops sending the response request signal. As described above, when the reservation signal is received again before the response signal from the portable device 20 is received, and the reception status of the reservation signal satisfies the predetermined condition, that is, in the case of the present embodiment, within the predetermined time. When the number of reservations exceeds a predetermined number, the transmission of the response request signal is stopped to provide a function for reserving the unlocking and opening of the vehicle door D from a distance, and the reservation operation is repeated many times. Even if it is performed, the door control system 100 which suppresses consumption of the battery of the vehicle C can be provided.

  In this embodiment, the reservation signal monitoring unit 16 is a counting unit that counts the number of times the reservation signal is received within a predetermined time. The predetermined condition in the determination unit 17 is that the number of receptions counted by the counting unit is a predetermined number of times. It is to exceed. That is, the door control system 100 accepts a reservation operation if a predetermined number of times is not exceeded even if a plurality of reservation operations are performed within a predetermined time. In this way, it is possible to determine the reception status of the reservation signal based on the number of times the reservation signal is received within a predetermined time.

<First Modification of First Embodiment>
With reference to FIG. 5, the modification of the control apparatus 10 of the door control system 100 and the control method of the portable device 20 is demonstrated. In order to avoid duplicate descriptions, the differences will be mainly described. S300 to S330 are the same as S100 to S130 described above. Moreover, since the control method of the portable device 20 is the same as that in the above embodiment, the description thereof is omitted.

  When the control device UHF reception unit 11 does not receive a response signal, the control device UHF reception unit 11 is configured so that the operation unit 25 always accepts a reservation operation in S330, and the reservation operation can be performed a plurality of times. Therefore, in addition to the reservation signal received in S300, it is checked whether the reservation signal has been received again. If not received, the process returns to S314 to check whether or not a predetermined time (T1) has elapsed. If not, a response request signal is transmitted in S316 and the predetermined time (T1) is transmitted. Until the time elapses, the response signal is received, or the reservation signal is received, the loop of S314, S316, S318, and S330 is repeated.

  When the reservation signal is received again, the control device storage unit 14 stores the reservation information included in the reservation signal and the identification number of the portable device 20 in S332. In S334, the control device control unit 13 detects the position of the door for which the unlocking / opening reservation is made in the reservation information (the direction in which the user approaches the vehicle as viewed from the vehicle). In S336, the control device control unit 13 sets the direction in which the response request signal is transmitted based on the reserved door position. In step S338, the control device UHF transmission unit 121 transmits information indicating that the PSD unlocking / opening is permitted to the portable device 20 as a reservation acceptance signal, returns to step S314, and the reservation set in step S312 is valid. It is inspected whether or not the time (T1) has elapsed.

  That is, when the control device UHF receiving unit 11 receives the reservation signal again before receiving the response signal corresponding to the response request signal, the determination unit 17 does not satisfy the predetermined condition of the reception status of the reservation signal ( If it is determined that the reservation is received at a predetermined time which is an effective time), the reservation processing unit 15 performs the reservation processing, and the control device LF transmission unit 122 continues to transmit the response request signal. As described above, when the reception status of the reservation signal does not satisfy the predetermined condition, the reservation process is performed, so that the intention of the user can be reflected and the consumption of the battery of the vehicle can be suppressed.

  If the reservation signal is not received again in S330, the process returns to S314 to check whether or not the predetermined time (T1) has elapsed. If it has elapsed, the reservation signal monitoring unit 16 determines in S340. Turn on the reservation prohibition flag. In other words, since the time for which the reservation is valid has expired, subsequent reservation operations are not accepted. In step S326, the control device control unit 13 clears the stored information and cancels the reservation made by the reservation processing operation. Since the operation unit 25 is configured to always accept a reservation operation, the control device 10 inspects reception of a reservation signal in S300. As a result of inspecting a reservation prohibition flag in S302, the reservation prohibition flag is turned on. Therefore, a reservation non-permission signal is transmitted in S328.

  In this embodiment, the reservation signal monitoring unit 16 is a time measuring unit that measures an elapsed time from the received reservation signal, and the predetermined condition in the determination unit 17 is that the elapsed time measured by the time measuring unit is a predetermined time. It is to exceed. According to this, it is possible to determine the reception status of the reservation signal based on the elapsed time from when the reservation signal is received.

<Second Modification of First Embodiment>
With reference to FIG. 6, the modification of the control apparatus 10 of the door control system 100 and the control method of the portable device 20 is demonstrated. In order to avoid duplicate descriptions, the differences will be mainly described. S400 to S430 are the same as S100 to S130 described above. Moreover, since the control method of the portable device 20 is the same as that in the above embodiment, the description thereof is omitted.

  When the control device UHF receiving unit 11 does not receive the response signal, the control device UHF receiving unit 11 can perform the reservation operation a plurality of times in S430, so that in addition to the reservation signal received in S400, the reservation signal is received again. Check if received. If not, the process returns to S414 to check whether one of the predetermined times (T1) set in S412 has elapsed. If not, the response request signal is transmitted in S416. The loop of S414, S416, S418, and S430 is repeated until a predetermined time (T1) elapses, a response signal is received, or a reservation signal is received.

  When the reservation signal is received again, the control device controller 13 checks in S432 whether or not the other predetermined time (T2) set in S412 has elapsed. The reservation signal monitoring unit 16 counts the first reservation count (N) in S434 if it has not elapsed, and counts the second reservation count (M) in S438 if it has elapsed. When the first reservation count (N) is counted in S434, the determination unit 17 checks in S436 whether or not the reservation count is within a predetermined number (X). In S438, the second reservation count (M ), The determination unit 17 checks whether or not the number of reservations is within a predetermined number (Y) in S440, and if both are within the predetermined number, the process returns to S404. After a series of reservation processing operations, the loop of S414, S416, S418, S430 to S440 is repeated until a predetermined time (T1) elapses, a response signal is received, or a reservation signal is received. .

  In S436 or S440, if any number of reservations exceeds the predetermined number, the reservation signal monitoring unit 16 turns on the reservation prohibition flag in S442 and does not accept subsequent reservation operations. For example, when the predetermined time T1 is set to 30 minutes and the predetermined time T2 is set to 5 minutes, when the operation unit 25 performs a reservation operation again within 5 minutes from the first reservation operation, the first reservation count (N ) Is within X times, the reservation is accepted, and if the operation unit 25 is reserved again within 30 minutes after the elapse of the first reservation operation, if it is within Y times, it will exceed X times. As well as accepting reservations. In this way, by changing the number of times a re-reservation is accepted according to the elapsed time from the first reservation operation, flexible reservation processing can be performed, reflecting the user's intention and suppressing vehicle battery consumption. Can do.

  Similar to the above embodiment, the control device 10 transmits a reservation non-permission signal in S444, clears the stored information in S426, and cancels the reservation made in the reservation processing operation. After that, even if the control device 10 receives the reservation signal in S400, the reservation prohibition flag is turned on as a result of checking the reservation prohibition flag in S402, and therefore the reservation prohibition signal is transmitted in S428.

  In addition, this invention is not limited to the illustrated Example, The implementation by the structure of the range which does not deviate from the content described in each item of a claim is possible. That is, although the present invention has been particularly illustrated and described with respect to particular embodiments, it should be understood that the present invention has been described in terms of quantity, quantity, and amount without departing from the scope and spirit of the present invention. In other detailed configurations, various modifications can be made by those skilled in the art.
