Description

  The present invention relates to a vehicle memory seat system capable of storing a seat position or posture of a driver's seat of a vehicle so that the stored position or posture can be reproduced, and in particular, a vehicle door key is inserted into a door keyhole. The present invention relates to a memory seat system incorporated in a vehicle provided with a keyless entry system that enables locking and unlocking of a door without any trouble.

  It has been proposed to combine a keyless entry system that enables locking and unlocking of a vehicle door by operation of a vehicle remote controller and a memory seat system (see, for example, Patent Document 1 and Patent Document 2).

  The conventional memory seat system applied to the combination of these two systems is not limited to the driver's seat, but in addition to the driver's seat, the position of the movable part related to the driving operation such as the steering wheel, mirror, pedal or the like By storing the posture, it has a function of reproducing those memory positions.

  In this conventional memory seat system, the positions and postures of the driver seat and the movable parts are adjusted so as to be optimal for each driver. By operating each memory switch SW provided in the vehicle in an optimally adjusted state, the optimal memory position for each driver is stored in the memory seat system. After storing the memory position, by operating the memory switch SW, each memory position stored corresponding to the operated memory switch SW can be called, and thus the called memory position can be reproduced. .

  In such a conventional keyless entry system, when one vehicle is shared by a plurality of drivers, identification information is provided for each driver, that is, for each intelligent key such as a remote controller possessed by each driver. A certain ID is assigned. When one of these drivers unlocks the vehicle door by operating the remote controller he or she owns, the keyless entry system uses the unique ID information given to each controller that each driver has. Receive from the remote controller. The keyless entry system determines whether or not the received ID information matches the ID information registered in the keyless entry system in advance, and sends the ID information to the memory sheet system when they match.

  In another conventional keyless entry system, each of the driver door, the passenger door, the back door, or the trunk lid is received in a state where unique ID information registered in advance is received from an intelligent key such as an ID card. When a so-called door request switch provided for a door lock / unlock switch request is operated, the lock / unlock state of the corresponding door is switched, and at the same time as this locking or unlocking, a keyless entry system Sends unique ID information to the memory sheet system.

  When the conventional memory sheet system receives ID information from a keyless entry system such as these intelligent key systems, it corresponds to the corresponding ID information among the memory positions stored corresponding to each ID information. The memory position information is read out, and in accordance with this position information, an optimal preset memory position for each driver corresponding to each ID information is reproduced.

Further, in such a memory sheet system, the above-described memory switch SW can be shared for each setting of the audio device and the air conditioner system. By sharing the memory switch SW, it is possible to store a favorite state for each occupant by operating the memory switch SW, such as audio volume, radio channel selection, air conditioner set temperature or selection of the air outlet, etc. After the storage, the user can call the favorite state set for each according to the operation of the memory switch SW. Thereby, an audio apparatus and an air conditioner can be operated in the preset favorite state.
JP 2002-47836 A (Page 6-8, FIG. 3) JP-A-6-320990 (page 3-6, FIG. 1)

  In the above-described conventional technology, it is necessary to determine whether or not the memory position such as the driver's seat needs to be regenerated when the door is opened, that is, to move to a dedicated memory position that is optimal for each driver. This determination is made based on ID information from a keyless entry system such as an intelligent key system. In other words, the door opening operation is performed based on the unlocking operation information for opening the door. However, it is not determined whether or not the unlocking operation is due to the operation of the driver sitting on the driver's seat.

  Therefore, for example, if an occupant with an intelligent key given a unique ID performs an unlocking operation on the door and sits in the passenger seat from the passenger door, the memory seat system is the driver who performs the unlocking operation. Since it is erroneously determined that there is a driver seat, the driver seat is erroneously set to the memory position set for the person sitting in the passenger seat. In this case, the driver who sits on the driver's seat from the driver's seat door after the unlocking operation uses the vehicle as the driver ahead of the vehicle, and therefore has already been driven to the optimum memory position for the driver. Even if a seat has been set, or even if the driver who subsequently tries to drive the vehicle has his / her own intelligent key, the driver's seat has been seated in the passenger seat first. By the unlocking operation of the person, the memory position corresponding to the unique ID information of the person sitting in the passenger seat is erroneously changed from the optimal memory position for the person who wants to drive.

  In such a case, the driver who sits on the driver's seat later will again operate the memory switch SW that has registered the memory position optimal for the driver's seat etc. There was a need to do.

  An object of the present invention is to provide a memory seat system that can reduce the necessity of resetting a driver's seat due to such erroneous determination, thereby reducing the troublesomeness of resetting.

  The present invention is based on the basic concept of determining whether or not the door unlocking operation is based on the operation of the driver sitting on the driver seat.

  For this determination, the first invention basically uses the door information that is opened first after the unlocking operation by the keyless entry system.

  The first aspect of the present invention stores the position or posture of a driver's seat of a vehicle in which a keyless entry system capable of locking and unlocking a door without inserting a key into a keyhole is stored. In a memory sheet system having a function of reproducing a memory position such as a posture, when a memory position corresponding to unique identification information obtained by the keyless entry system is reproduced, it is first opened after an unlocking operation by the keyless entry system. It is determined whether or not to reproduce the memory position based on the door information.

  In the first aspect of the present invention, as described above, by determining whether or not to reproduce the memory position of the driver's seat based on door information that is first opened after the unlocking operation by the keyless entry system, For example, even if the unlocking operation is already performed by a person sitting in the passenger seat, if the passenger door is detected to be opened in order to sit in the passenger seat, the person sitting in the passenger seat is detected based on the door information. A change to the memory position corresponding to the unique ID information is prevented.

  Therefore, as long as the driver corresponding to the unique ID information of the memory position that has already been set before the unlocking operation performed by the person sitting in the passenger seat continues to drive, the original memory position that is optimal for this driver is maintained. Therefore, it is not necessary to operate the memory switch SW as in the prior art, thereby relieving the driver from the troublesome operation of the memory switch.

  According to the second aspect of the present invention, in order to determine whether or not the unlocking operation is performed by the operation of the driver sitting on the driver's seat, operation information on the door request switch provided on the driver's seat door is basically used. Is used.

  In the second aspect of the present invention, each of a plurality of doors including a driver's seat door of a vehicle is received without receiving or operating a key in a keyhole under reception of identification information that matches unique identification information registered in advance. The position or posture of the driver's seat of a vehicle in which an intelligent key system that enables at least locking and unlocking of the door provided with the switch is touched is stored by touching any of the switches provided on the vehicle. In the memory seat system having the function of reproducing the memory position such as the memory position or the memory attitude, the intelligent key system receives when the unlocking operation is performed by the operation of the switch provided on the driver's seat door. Reproducing the memory position of the sheet corresponding to the unique identification information; And butterflies.

  In the second aspect of the present invention, when the unlocking operation is performed by operating the switch provided on the driver's seat door, the memory position corresponding to the unique identification information received by the intelligent key system is reproduced. Under circumstances, the reproduction or change of the memory position is prevented, and the storage position or the storage posture which is the original position before the unlocking operation is maintained.

  When the unlocking operation is performed by operating the switch provided on the driver's seat door, it can be determined that the person who performed the unlocking operation becomes the driver.

  In addition, when the unlocking operation is performed by the request switch provided on the passenger seat door or the rear door, for example, when the unlocking operation is performed by the operation of the switch provided on the driver seat door, It can be judged that it is not. In this case, since the memory position is prevented from being reproduced, that is, changed, and the original memory position is maintained, as described above, in the situation where the previous driver continues to drive, for example, a person sitting in the passenger seat The change to the memory position corresponding to the unique ID information in the performed unlocking operation is prevented, thereby releasing the driver from the troublesome operation of regenerating the memory position.

  According to the third aspect of the present invention, in order to determine whether or not the unlocking operation is based on the operation of the driver sitting on the driver's seat, the operation key of the driver's seat door and the intelligent key that is the transmission source are basically used. Use location information.

  According to the third aspect of the present invention, each of a plurality of doors including a driver's seat door of a vehicle is received without receiving a key into a keyhole or operating it under reception of identification information that matches unique identification information registered in advance. By touching any of the provided switches, at least the position or posture of the driver's seat of the vehicle incorporating the intelligent key system that enables locking and unlocking of the door provided with the switch is stored, In the memory seat system having the function of reproducing the memory position such as the memory position or the memory attitude, the driver seat door of the vehicle is opened and the transmission source of the unique identification information received by the intelligent key system is the driver seat door The unique key system receives the unique key system when determined to be in the vicinity. Characterized in that it reproduces the memory position of the seat corresponding to different information.

  In the third invention, when the driver's seat door of the vehicle is opened and it is determined that the transmission source of the unique identification information received by the intelligent key system is near the driver's seat door, the intelligent key system receives it. The memory position corresponding to the unique identification information to be reproduced is reproduced. Under other circumstances, the reproduction or change of the memory position is prevented, and the original memory position before the unlocking operation is maintained.

  When the driver's seat door of the vehicle is opened and the source of the unique identification information received by the intelligent key system is in the vicinity of the driver's seat door, the person holding the intelligent key corresponding to the unique identification information sits on the driver's seat Therefore, reproduction of the memory position corresponding to the unique identification information is permitted.

  Other than when it is determined that the driver's seat door of the vehicle is opened and the transmission source of the unique identification information received by the intelligent key system is in the vicinity of the driver's seat door, for example, a person who owns the intelligent key but does not drive the back door When is operated, the memory position is prevented from being reproduced, that is, changed, and the original memory position before the unlocking operation is maintained. Accordingly, as described above, the change to the memory position can be prevented, so that when the previous driver continues to drive, the driver is released from the troublesome operation of regenerating the memory position.

  According to the first aspect of the present invention, as described above, based on the door information that is first opened after the unlocking operation by the keyless entry system, the memory position such as the storage position or the storage posture of the driver seat is reproduced. By determining whether or not to perform, even if a person sitting in the passenger seat performs an unlocking operation, for example, a change to the memory position corresponding to the unique ID information of the unlocking operator can be prevented. Therefore, as long as the driver corresponding to the unique ID information of the memory position that has already been set before the unlocking operation continues to operate, there is no need to operate the memory switch SW as before. Therefore, the need for resetting the driver's seat due to an erroneous determination by the driver can be reduced, and the troublesomeness of resetting can be reduced.

  According to the second aspect of the present invention, as described above, when it is determined that the unlocking operation is performed by operating the switch provided on the driver's seat door, the unique identification information received by the intelligent key system is included in the unique identification information received by the intelligent key system. The memory position such as the storage position or storage posture of the corresponding driver seat is reproduced, and under other circumstances, the original memory position before the unlocking operation is maintained, so as in the first invention, The necessity of resetting the driver's seat due to a driver's erroneous determination is reduced, and the troublesomeness of resetting can be reduced.

  According to the third invention, as described above, when the driver's seat door of the vehicle is opened and the transmission source of the unique identification information received by the intelligent key system is near the driver's seat door, the intelligent key system is The memory position such as the storage position or storage posture of the driver's seat corresponding to the received unique identification information is reproduced, and under other circumstances, the original memory position before the unlocking operation is maintained. As in the second invention, the necessity of resetting the driver's seat due to a driver's erroneous determination is reduced, and the troublesomeness of resetting can be reduced.

  The features of the present invention will become more apparent from the following description along with the illustrated embodiments.

<Example 1>
FIG. 1 schematically shows a part of a circuit configuration of an automobile provided with a memory seat system and a keyless entry system according to the present invention.

  A memory seat system 10 according to the present invention is incorporated in a vehicle 12 such as an automobile in association with a keyless entry system 11 as shown in FIG.

  As is well known in the art, the keyless entry system 11 includes, for example, a plurality of remote controllers 14 provided with operation buttons 13a and 13b for locking and unlocking the door of the vehicle 12 (in FIG. And a control circuit 15 capable of receiving a radio signal from the remote controller. Each remote controller 14 is a unique identification signal given to each remote controller 14 together with a door locking control signal or a door unlocking control signal corresponding to the operation button when the operation buttons 13a and 13b are operated. The signal is output to the control circuit 15.

  As is well known in the art, the keyless entry system 11 stores in advance ID signal information assigned to each intelligent key such as each remote controller 14. When receiving the ID signal from the remote controller 14, the control circuit 15 compares the received ID signal with each ID information stored in the keyless entry system 11 to identify the received ID signal. When it is determined that the received ID signal is one of the ID signals stored in advance based on the identification of the received ID signal, the control circuit 15 causes the door actuator 16 provided on each door of the vehicle 12 to The door is locked and unlocked with each other. Therefore, the locked or unlocked state of each door can be switched between each other without inserting a key (not shown) into the keyhole of the door and without operating the key.

  The control circuit 15 can communicate with an intelligent key (not shown) such as an intelligent card, as is well known in the art. The control circuit 15 manually touches the lock / unlock request switch 17 incorporated in the operation handle of each door under the reception state of the ID signal indicating the unique identification information given to the intelligent key. Then, the door actuator 16 is operated by this switch operation. Accordingly, as described above, the doors can be switched between the locked state and the unlocked state without inserting a key (not shown) into the keyhole of the door and without operating the key.

  Further, when receiving the unique ID signal stored in advance from the remote controller 14 or the intelligent key, the control circuit 15 outputs the unique ID information to the memory sheet system 10.

  The memory seat system 10 that receives the ID information from the control circuit 15 is for adjusting the position or posture of each movable part related to the driving operation such as the steering angle, the mirror angle, and the operation pedal in addition to the driver seat 18. An actuator 19 and a memory sheet controller 20 for controlling the operation of each actuator 19 are provided. The memory seat controller 20 stores position information about the position or posture of each movable part such as each driver's seat 18 for each unique ID signal described above. Each memory position information is stored in each memory position information. It is stored in association with the signal. Based on the memory position information stored in the memory seat controller 20 and the state signal indicating the state of the control target from each actuator 19, for example, the front / rear position, the height position, or the backrest of the driver's seat 18 is determined. The angle can be set for each state stored for each ID signal, and the other movable parts can be similarly set for each state stored for each ID signal.

  In order to store the memory position for each ID signal in the memory seat controller 20 and to reproduce each memory position such as the driver's seat 18 by manual operation, a conventionally well-known memory switch 21 (21a to 21d) is provided in the vehicle interior. Is provided.

  Each memory position can be assigned to each operation unit 21a to 21c of the memory switch 21 for each ID information of the remote controller 14 described above. For example, by selectively pressing the operation units 21a to 21c of the memory switch 21 for each person who owns each remote controller 14, the operation units are designated, and the position or posture of each movable unit is adjusted. Thereafter, by operating the set operation unit 21d, the memory position for each ID information can be stored corresponding to each of the operation units 21a to 21c. Accordingly, by selecting and operating each of the operation units 21a to 21c by manual operation of the memory switch 21, it is possible to reproduce the memory position corresponding to the ID information assigned to each of the memory switches 21a to 21c.

  In addition, the memory seat controller 20 includes a lock / unlock provided in the driver's seat door of the lock / unlock request switch 17 provided in each door and the ID signal from the control circuit 15. When the operation signal from the request switch 17 is received, the memory position corresponding to the ID signal of each movable part such as the driver's seat 18 is controlled by controlling the operation of the actuator 19 without manually operating the memory switch 21. Reproduce.

  In the example shown in the figure, the audio device 22 and the air conditioner device 23 receive the above-mentioned unique ID information from the control circuit 15 in order to operate in each desired operation state set for each ID information. 21 receives a memory signal selection signal. Accordingly, in the same manner as the reproduction of the memory position such as the driver seat 18 described above, the ID stored in advance corresponding to the ID information corresponding to the operated operation units 21a to 21c by operating the memory switch 21, for example. The desired operating state for each information can be reproduced.

  In the memory seat system 10, as described above, the door can be unlocked by pressing the operation buttons 13 a and 13 b of the remote controller 14, or a lock / unlock request by a passenger having the intelligent key. The door can be unlocked by touching the switch 17. When such an unlocking operation is performed, the memory seat controller 20 receives the unique ID signal from the control circuit 15, and each of the movable parts such as the driver's seat 18 is set to the memory position corresponding to the unique ID signal. Reproduce. Further, the audio device 22 and the air conditioner device 23 are operated in a favorite state set in advance corresponding to the unique ID signal.

  Therefore, as long as the person who performs the unlocking operation is seated in the driver's seat for driving the vehicle 12, the memory seat system 10 reliably sets each movable part such as the driver's seat 18 in an optimal state for the driver. Since the auxiliary devices such as the audio device 22 and the air conditioner device 23 are operated in a preset state of each driver, reproduction of the memory position of the memory seat system 10 does not cause a malfunction.

  However, if the person who performed the unlocking operation does not sit on the driver's seat as a driver and another person different from the unlocking operator sits on the driver's seat as a driver after this unlocking operation, Since each operation unit such as the seat 18 is reproduced in the memory position of the unlocking operator, the memory seat system 10 results in erroneous determination that the unlocking operator is the driver. It becomes.

  Even if each operation unit such as the driver's seat 18 is regenerated to a memory position different from the driver's memory position due to such an erroneous determination, each operation of the driver's seat 18 or the like by the operation of the memory switch 21 is performed. The memory position of the driver who is seated on the driver's seat 18 with respect to the operation unit can be reproduced.

  However, in the memory sheet controller 20 of the memory sheet system 10 according to the present invention, the opportunity of operation of the memory switch 21 due to such erroneous determination is reduced, thereby reducing the troublesomeness due to the operation of the memory switch 21. Therefore, based on the ID signal from the control circuit 15 and vehicle door information, automatic regeneration of the memory position of each movable part such as the driver's seat 18 is controlled.

  That is, the memory sheet controller 20 of the memory sheet system 10 according to the present invention receives each door information signal from the door switches 24a to 24d provided at each door and detecting the open / closed state of each door. The door information signal indicating whether each door is in an open state or a closed state indicates that the audio device 22 and the air conditioner device 23 are in a preset state as in the case of the reproduction of the memory position of the driver's seat 18 or the like. In order to operate, the audio device 22 and the air conditioner device 23 are also output.

  For example, the door switch 24a is provided on the driver's seat door to detect the open / closed state of the driver's seat door, and the door switch 24b is provided on the passenger's seat door to detect the open / closed state of the passenger seat door. The two door switches 24c and 24d are provided in each rear door in order to detect the open / closed state of the left and right rear doors.

  In the memory seat system 10 according to the present invention, when the unlocking operation is performed by the operation of the operation button 13b of the remote controller 14 or the contact of the lock / unlock request switch 17 by the passenger having the intelligent key, As described above, the controller 20 starts the reproduction of the movable parts such as the driver's seat 18 to the memory position. However, the memory seat controller 20 determines that the first opened door after the start of the regeneration of the memory seat position is not the driver's seat door based on the door opening / closing information input from the door switches 24a to 24d. If it is determined that the opened door is a door other than the driver's seat door, the regeneration of the driver's seat 18 or the like to the memory position is stopped and returned to the original position, or the regeneration of the driver's seat 18 or the like that has completed the regeneration. Return to the original position.

  The operation of the memory sheet system 10 and the keyless entry system 11 according to the present invention will be described with reference to the flowchart 110 shown in FIG.

  The control circuit 15 of the intelligent system using the above-described intelligent key or the keyless entry system receives whether or not the ID signal matching the unique identification signal stored in advance together with the door unlocking control signal is received from the remote controller 14. Determine (step S10).

  When the control circuit 15 determines that the received unique ID signal matches that recorded in advance, the unique ID signal is added to the memory sheet controller 20, the audio device 22 and the air conditioner device 23 as described above. And output. The memory sheet controller 20 determines whether or not the ID signal input from the control circuit 15 is an ID signal associated with the operation units 21a to 21c of the memory switch 21 (step S11).

  When it is determined that the ID signal input to the memory seat controller 20 corresponds to any one of the operation units 21a to 21c, the memory seat controller 20 uses the state detection signal supplied from each actuator 19 to drive the driver seat 18. It is determined whether or not each movable operation unit such as is in the memory position of the ID signal input to the memory sheet controller 20 (step S12).

  If the memory seat controller 20 is not in the memory position of the ID signal input by each movable operation unit such as the driver's seat 18, that is, if the current seat position or the like is different from the memory position of the input ID signal, the memory seat controller 20 The movement of the driver's seat 18 or the like is started toward the memory position corresponding to the ID signal as the position, thereby starting the reproduction of the requested memory position, and this reproduction is completed (step S13).

  After completion of the regeneration in step S13, the memory seat controller 20 determines whether or not the first opened door is a driver's seat door based on the door opening / closing information from each of the door switches 24a to 24d (step S14). .

  If it is determined that the door that is opened first is the driver's seat door, the driver's seat 18 or the like is held in its regeneration position, and the driver's seat 18 or the like is set to the requested memory position. On the other hand, if it is determined in step S14 that the first opened door is a door other than the driver's seat door, the driver's seat 18 and the like in the regeneration position are returned to the original memory position (step S15).

  In step S13, the reproduction of the memory position is not completed, and then the reproduction is interrupted for the determination in step S14. In response to the determination result in step S14, the original memory position is returned from the interruption position in step S15. Or playback of the memory position can be continued from the interruption position.

  In step S11, it is determined that the ID signal input from the control circuit 15 is a signal other than the ID signal associated with the operation units 21a to 21c of the memory switch 21, and in step S12, each of the driver seat 18 and the like is determined. If it is determined that the movable operation unit is at the memory position of the ID signal input to the memory sheet controller 20, the control circuit 15 returns to step S10 in order to wait for reception of a new ID signal. Similarly, when the memory position reproduced by the determination result in step S14 is held, or when the return to the original memory position in step S15 is completed, the process returns to step S10, and the control circuit 15 sends a new ID signal. Wait for reception.

  If it is determined in step S10 that the control circuit 15 has not received an ID signal that matches the unique identification signal stored in advance, the memory sheet controller 20 performs each operation of the memory switch 21 following this determination. Whether or not the units 21a to 21c are operated is determined based on the presence or absence of an operation signal from each operation unit (step S16).

  If it is determined in step S16 that the operation units 21a to 21c are not operated, the process returns to step S10, and the control circuit 15 waits for reception of a new ID signal. On the other hand, if it is determined in step S16 that the operation units 21a to 21c have been operated, the memory seat controller 20 causes each movable operation unit such as the driver's seat 18 to have an ID corresponding to the operated operation unit 21a to 21c. It is determined whether or not the signal is in the memory position (step S17).

  In step S17, the current seat position or the like is different from the memory position of the input ID signal. Therefore, it is necessary to move the driver seat 18 or the like toward the memory position corresponding to the ID signal which is the requested memory position. If it is determined that there is, the movement of the driver's seat 18 or the like is started toward the memory position corresponding to the ID signal that is the requested memory position, and when the reproduction of the requested memory position is completed, Returning to S10, the control circuit 15 waits for reception of a new ID signal.

  On the other hand, if it is determined in step S17 that each movable operation unit such as the driver's seat 18 is at the memory position of the ID signal input to the memory seat controller 20, the process returns to step S10, and the control circuit 15 sends a new ID signal. Wait for reception.

  The above-described loops of Steps S10 to S18 are repeated regardless of whether the engine is operating or stopped unless a power source such as a battery is removed by a well-known sleep circuit, for example, which is not shown. .

  In the memory sheet system 10 according to the first embodiment of the present invention, as described above, the ID signal, which is unique identification information obtained from the control circuit 15 of the keyless entry system 11 by the unlocking operation, is the operation unit 21a of the memory switch 21. It is determined in step S11 that it is associated with .about.21c, and it is necessary to move the driver's seat 18 or the like toward the memory position corresponding to the ID signal which is the requested memory position in the subsequent step S12. If it is determined that, the reproduction of the requested memory position is started in step S13, and the requested memory position is reproduced.

  If it is determined in step S14 following step S13 that the door opened first is the driver's seat door, the regenerated memory position is retained, so the driver's seat 18 and the like are unlocked. It is set to the most suitable memory position for the person who performed.

  Therefore, in this case, when a person who has performed the unlocking operation drives the vehicle 12, an optimal memory position can be obtained for each operation section such as the driver seat 18 without operating the memory switch 21. Further, when a person other than the driver wants to drive, an optimum memory position can be obtained for each operation portion such as the driver's seat 18 by operating the memory switch 21.

  On the other hand, if it is determined in step S14 that the first opened door is a door other than the driver's seat door, the driver's seat 18 and the like are returned to their original positions before the start of regeneration. The driver's seat 18 and the like are maintained at the original positions before the unlocking operation.

  Therefore, when a person other than the driver of the vehicle 12 tries to drive, if an optimum memory position is to be obtained for the driver, the adjustment operation by the operation of the memory switch 21 or the manual operation of each operation unit is performed. Is required.

  However, when the driver ahead of the vehicle 12 intends to continue driving this time, the driver's seat 18 and the like are held in an optimal state, so that a memory switch for obtaining an optimal memory position at this time The operation 21 is not necessary.

  Therefore, when the driver of the vehicle 12 tries to continue driving this time, even if the unlocking operation is performed by another person, it is not necessary to perform the operation of the memory switch 21 as before. As a result, the driver is relieved from the troublesome operation of the memory switch 21, so that the necessity of resetting the driver's seat 18 and the like due to the erroneous determination of the driver is reduced, and the troublesomeness of the resetting is reduced. Is possible.

<Example 2>
In the first embodiment, if it is determined in step S12 that the memory position of the ID signal input to the memory sheet controller 20 is different from the current sheet position or the like, without waiting for the determination on the door information obtained in step S14, In step S13 subsequent to step S12, the movement of the driver's seat 18 or the like is started toward the requested memory position. After the memory position is regenerated, whether the regenerated memory position is returned to the original memory position in step S14. Judged whether or not.

  Instead, as shown in the flowchart 120 of the second embodiment shown in FIG. 3, it is determined whether or not the reproduction is necessary based on the door information (step S23), and the reproduction of the memory position is necessary. Only when the determination result is obtained, the movement of the driver's seat 18 or the like can be started toward the requested memory position (step S24).

  In the flowchart 120, in step S20 similar to step S10, it is determined whether or not the control circuit 15 has received an ID signal that matches a unique identification signal stored in advance.

  If it is determined that the received unique ID signal matches that recorded in advance, the unique ID signal is output to the memory sheet controller 20 as described above. The memory sheet controller 20 determines that the ID signal is an ID signal associated with the operation units 21a to 21c of the memory switch 21 (step S21). In step S22 similar to step 12 described above, the memory sheet controller 20 If it is determined that the memory position of the input ID signal is different from the current seat position, etc., in step S23 subsequent to step S22 prior to reproduction of the input ID signal memory position, the door information is the same as in step 14. Judge about. Based on this determination, the memory sheet controller 20 reproduces the memory position.

  Therefore, according to the second embodiment shown in the flowchart 120, the return step S15 from the reproduced memory position to the original memory position shown in the first embodiment is not necessary, and the configuration of the memory sheet system 10 can be simplified. .

  If it is determined in step S20 that the control circuit 15 has not received an ID signal that matches the unique identification signal stored in advance, the memory controller 20 determines whether the memory switch 21 is in step S25 similar to step S16. Whether or not each of the operation units 21a to 21c has been operated is determined based on the presence or absence of an operation signal from each of the operation units. If it is determined that the operation units 21a to 21c are not operated, the process returns to step S20 in order to wait for reception of a new ID signal, as in the first embodiment. If it is determined in step S25 that the operation units 21a to 21c have been operated, in step S26 similar to step S17, the movable operation units such as the driver's seat 18 are moved to the operated operation units 21a to 21c. It is determined whether or not the memory position of the corresponding ID signal exists. As in the first embodiment, when the presence determination result is obtained, the process returns to step S20. When the determination result is NO, the memory position is reproduced in step S27 similar to step S18. Then, in order to wait for reception of a new ID signal, the process returns to step S20.

<Example 3>
Example 1 and Example 2 both show an example in which it is determined whether or not to reproduce the memory position based on door information that is first opened after the locking operation.

  In the third embodiment shown in FIG. 4, the memory position is determined based on information from a door lock / unlock request switch 17 (see FIG. 1) provided on each door for locking or unlocking each door of the vehicle 12. An example of determining whether or not to perform the reproduction will be shown.

  A flowchart 130 shown in FIG. 4 is an example of an intelligent key system using an intelligent key that transmits a unique ID signal by communication with the control circuit 15 shown in FIG. 1, and the control circuit 15 receives the intelligent key from the intelligent key. It is determined whether an ID signal that is an identification signal given to the key is received (step S30).

  If it is determined that the received unique ID signal matches that recorded in advance, the unique ID signal is output to the memory sheet controller 20 as described above.

  In the flowchart 130 showing the third embodiment, the memory sheet controller 20 determines in step S31 that is similar to step S21 in the flowchart 120 that the ID signal is an ID signal associated with the operation units 21a to 21c of the memory switch 21. Then, in step S32 similar to step 22 described above, it is determined whether the memory position of the ID signal input to the memory sheet controller 20 is different from the current sheet position or the like. If it is determined that they are different, it is determined in the subsequent step S33 whether or not an operation for unlocking the door of the vehicle 12 has been performed on the driver's seat door by a signal from the request switch 17 provided on each door. .

  If the memory seat controller 20 determines that the signal is from the request switch 17 provided on the driver's seat door, the memory seat controller 20 first determines that the driver's seat door is opened. Based on this determination, the memory seat controller 20 determines in step 24 described above. The memory position is reproduced in the same step S34.

  Therefore, according to the third embodiment shown in the flowchart 130, the door request switch 17 provided on the driver's seat door is replaced with the determination as to whether or not the first door to be opened shown in the second embodiment is the driver's seat door. Whether or not the unlocking operation has been performed is determined, and the determination result determines whether or not to reproduce the memory position. This prevents the memory position from being regenerated when the first unlocking operation is performed on anything other than the driver's seat door, so that the memory switch 21 is not operated by the previous driver. An optimal seat position and the like for the driver can be obtained without bothering.

  When the memory sheet controller 20 determines in step S31 that the received unique ID signal is not associated with the memory switch 17, or in step S32, it is determined that the memory position of the ID signal is not different from the current sheet position or the like. In such a case, as in the second embodiment, the process returns to step S30 in order to wait for reception of a new ID signal.

  If it is determined in step S30 that the control circuit 15 has not received an ID signal that matches the unique identification signal stored in advance, the control circuit 15 determines whether the memory switch 21 is in step S35 similar to step S25. Whether or not each of the operation units 21a to 21c has been operated is determined based on the presence or absence of an operation signal from each of the operation units. If it is determined that the operation units 21a to 21c are not operated, the process returns to step S30 in order to wait for reception of a new ID signal. If it is determined in step S35 that the operation units 21a to 21c are operated, in step S36 similar to step 26, each movable operation unit such as the driver's seat 18 corresponds to the operated operation units 21a to 21c. It is determined whether or not it is in the memory position of the ID signal. When the presence determination result is obtained, the process returns to step S30. When the determination result is NO, the memory position is reproduced in step S37 similar to step S27, and then a new ID signal is obtained. The process returns to step S30 in order to wait for reception. The flow of these steps excluding the determination contents of step 32 is basically the same as in the second embodiment.

<Example 4>
The third embodiment shows an example in which it is determined whether or not to reproduce the memory position based on information from the door lock / unlock request switch 17 (see FIG. 1).

  The fourth embodiment shown in FIG. 5 is a source of this ID signal when the driver's seat door of the vehicle 12 is opened and the control circuit 15 shown in FIG. 1 receives an ID signal stored in advance from the intelligent key. This is an example of determining whether or not to regenerate the driving seat 18 or the like based on whether or not the intelligent key is in the vicinity of the driver's seat door.

  As in the third embodiment, a flowchart 140 shown in FIG. 5 is an example of an intelligent key system using an intelligent key that transmits a unique ID signal by communication with the control circuit 15 shown in FIG.

  In the embodiment shown in the flow chart 140, the control circuit 15 or the memory seat controller 20 is operated by the door information signal from the door switch 24a provided on the driver's seat door of the vehicle 12, for example, by the presence / absence of the door signal. It is determined whether or not it is open (step S40).

  When it is determined that the driver's seat door is open, the control circuit 15 determines whether or not the ID signal received from the intelligent key by communication with the intelligent key matches the identification signal stored in advance. And whether or not the position of the transmission source of the ID signal is in the vicinity of the driver's seat door (step S41).

  The determination in step S41 can be made based on, for example, comparing the intensity of an ID signal received by an antenna provided at each door, or determining whether a transmission source is within a predetermined distance range from the driver's seat door. . If it is determined that the position of the transmission source of the ID signal is in the vicinity of the driver's seat door, the memory controller 20 determines whether or not the ID signal is an ID signal associated with the operation units 21a to 21c of the memory switch 21. Is determined (step S42).

  If it is determined that there is an association, the memory controller 20 subsequently determines whether or not the memory position of the ID signal input to the memory sheet controller 20 is different from the current sheet position or the like (step S43). If it is determined that they are different, the reproduction of the memory position is executed in the subsequent step S44 based on this determination.

  If the determination of each step in steps S40, 41 and 43 is NO, it is determined in step S45 whether or not each operation unit 21a to 21c of the memory switch 21 has been operated. Judgment is made based on the presence or absence of a signal. If it is determined that the operation units 21a to 21c are not operated, the process returns to step S40 in order to wait for reception of a new ID signal. If it is determined in step S45 that the operation units 21a to 21c are operated, in step S46 similar to step 36, each movable operation unit such as the driver's seat 18 corresponds to the operated operation units 21a to 21c. It is determined whether or not it is in the memory position of the ID signal. When the presence determination result is obtained, the process returns to step S40. When the determination result is NO, the memory position is reproduced in step S47 similar to step S37, and then a new ID signal is obtained. The process returns to step S40 to wait for reception. The flow from Steps 45, 46 and 47 back to Step S40 is the same as in the third embodiment.

  According to the fourth embodiment shown in the flowchart 140, as described above, when the driver's seat door of the vehicle 12 is opened and the source of the unique ID signal received by the control circuit 15 of the intelligent key system is near the driver's seat door. When it is determined that there is a memory position corresponding to the ID signal received by the intelligent key system, the memory position is reproduced or changed under other circumstances, and the original memory position is maintained. The

  Therefore, when the driver's seat door is opened and the source of the unique ID signal received by the intelligent key system is in the vicinity of the driver's seat door, the person holding the intelligent key corresponding to the ID signal is Since it can be determined that the user sits on the seat 18, reproduction of the memory position corresponding to the unique ID signal is permitted. As a result, the driver can sit on the driver's seat 18 for which the memory position is set for the driver, so that the optimum memory position can be obtained without operating the memory switch 21 again.

  For example, when a person who is not a driver having the intelligent key operates the back door, the memory position is prevented from being reproduced, that is, changed, and the original memory position is maintained. Accordingly, as described above, the change to the memory position can be prevented, so that when the previous driver continues to drive, the driver is released from the troublesome operation of regenerating the memory position.
