Hereinafter, embodiments according to the present invention will be described with reference to the drawings.
<First Example>
FIG. 1 is a block diagram of a child lock system 100 in this embodiment. The child lock system 100 includes a child lock control device 50 provided in the vehicle 1 and a portable device 60 that is carried by the user of the vehicle 1 and communicates with the child lock control device 50. The vehicle 1 includes a driver's seat door 2 (first door 2) that is mainly used when the driver gets in and out of the driver's seat, and a door other than the driver's seat door 2 that is mainly used by the passenger. A boarding seat door 3 (second door 3) used for getting on and off the rear seat is provided. Therefore, the vehicle 1 has at least two or more doors. In addition, the kind of door is a hinge door, a slide door, etc., The kind is not specifically limited. Further, the door may be manually opened and closed by operating the door knob, or the door may be automatically opened and closed when the door knob or a dedicated button is operated.

  The portable device 60 includes a communication means (not shown) for wirelessly transmitting and receiving signals at a communication frequency, which will be described later, and a storage means (not shown) for storing at least an authentication code (also referred to as an ID code). Prepare. The operation surface of the portable device 60 is provided with a child lock setting switch 61 described later. The function of the switch for setting the child lock may be used together with the door locking / unlocking switch (for example, when the door locking / unlocking switch is held down, the child lock is set / released). ), A dedicated switch independent of the door locking / unlocking switch may be provided.

  The child lock control device 50 includes a communication unit 70 having antennas 71 to 74 that communicate with the portable device 60, and a position determination unit 54 that determines the position of the portable device 60 based on a result of the communication unit 70 communicating with the portable device 60. Is provided. In this embodiment, these antennas include an indoor LF antenna 71 provided in the vehicle 1, an outdoor driver side LF antenna 72 provided on the driver's seat outside the vehicle, and an outdoor provided on the passenger seat outside the vehicle. A UHF receiver 74 that receives radio signals from the passenger-side LF antenna 73 and the portable device 60. Of course, more antennas may be arranged in addition to these antennas to perform fine position determination. The LF antennas 71 to 73 perform radio communication using radio waves in the LF (Low Frequency) band to the portable device 60, and the UHF receiver 74 performs radio communication using radio waves in the UHF (Ultra High Frequency) band from the portable device 60. .

  The position determination unit 54 transmits an LF band request signal from the indoor LF antenna 71, the outdoor driver's seat side LF antenna 72, and the outdoor passenger seat side LF antenna 73. The timing at which the position determination unit 54 transmits the request signal is not particularly limited, and may be based on some user operation (for example, an opening operation of a door knob) or periodically.

  When the portable device 60 receives the request signal in the LF band, the portable device 60 measures the LF strength (RSSI: Receive Signal Strength Indication), and transmits the LF strength information together with the authentication code on the response signal in the UHF band. When the UHF receiver 74 receives this response signal, the position determination unit 54 determines the position of the authenticated portable device 60 based on information in the response signal.

  The position determination unit 54 determines the position of the portable device 60 based on at most three types of LF intensity information obtained from the portable device 60. For example, when the LF intensity from the indoor LF antenna 71 is the strongest, the position determination unit 54 determines that the portable device 60 is in the vehicle 1. When the LF intensity from the outdoor passenger seat side LF antenna 73 is the strongest, the position determination unit 54 determines that the portable device 60 is outside the passenger seat side of the vehicle 1.

  When the position determination unit 54 determines the position of the portable device 60, the position determination unit 54 transmits the result to the unlock signal output unit 55 described later. For example, if the position determination unit 54 determines that the portable device 60 is in a room, the position determination unit 54 transmits the fact to the unlock signal output unit 55. In addition, the position determination of the portable device described above uses a technique used in a passive entry system in which a user carrying the portable device can lock and unlock the door only by grasping the door handle without operating the portable device, for example. In particular, the present invention is not limited to the above-described position determination method of the portable device.

  The child lock control device 50 includes a first inner knob opening operation input unit 51 that receives an opening operation signal of the inner knob 21 provided on the driver's seat door 2 (first door 2), and the passenger door 3 (second door). A second inner knob opening operation input unit 52 for receiving an opening operation signal of the inner knob 31 provided on the door 3) and an opening operation signal of the outer knob 22/32 provided on the driver's seat door 2 or the passenger door 3; An outer knob opening operation input unit 53 for receiving. When the user is on board and operates the inner knob 21/31 to open the door 2/3, the opening operation signal is sent to the first inner knob opening operation input unit 51 / second via the harness, respectively. This is transmitted to the inner knob opening operation input unit 52. When the user operates the outer knob 22/32 from outside and opens the door 2/3, the opening operation signal is transmitted to the outer knob opening operation input unit 53 via the harness.

  In addition, the child lock control device 50 includes an unlocking signal output unit 55 that outputs an unlocking signal to the locking / unlocking control unit 4 provided in each door 2/3. As described above, the unlock signal output unit 55 indicates that the opening operation has been performed from the first inner knob opening operation input unit 51, the second inner knob opening operation input unit 52, or the outer knob opening operation input unit 53. Further, the position information of the portable device 60 is obtained from the position determination unit 54 and the opening operation signal. Therefore, the unlock signal output unit 55 stores information on where the portable device 60 is located and which knob of which door is opened, and based on this information, the unlock control of each door is performed as follows. An unlock signal is output to the unit 4 or not.

  With reference to FIG. 2, the control step in the child lock control apparatus 50 of the child lock system 100 is demonstrated. The steps in the flowchart are abbreviated as S. The position determination unit 54 of the child lock control device 50 searches for the position of the portable device 60 by transmitting LF band request signals from all the LF antennas 71 to 73 in S100. If it does so, the portable device 60 which was in the range which can receive the request signal transmits the response signal of a UHF band.

  In step S <b> 102, the position determination unit 54 first checks whether the portable device 60 is in the vehicle 1 in order to determine the position of the portable device 60 based on the position information of the response signal from the portable device 60. When the position determination unit 54 determines that the portable device 60 is in the room, the unlock signal output unit 55 determines in S104 that the boarding seat door 3 (second door) near the seat where the child may be boarding. Even if the opening operation is performed with the inner knob 31 of 3), the unlocking signal is not output to the locking / unlocking control unit 4 of the door on which the opening operation has been performed, and the unlocking is not performed. This is because it is considered that the person who mainly holds the portable device 60 as a driver is in the car, and it may be dangerous for a child to open the door alone in such a case. It is because it should be kept.

  Note that when the position determination unit 54 determines that the portable device 60 is in the room and the opening operation is performed with the inner knob 21 of the driver's seat door 2 (first door 2), the driver's seat door 2 The unlocking signal is output to the locking / unlocking control unit 4 and unlocked. This is because there is no need to put a child lock on the normal driver's seat because no child is on board. Further, when the position determination unit 54 determines that the portable device 60 is in the room and the opening operation is performed with the outer knob 22/32 of any door, the door where the opening operation is performed The unlocking signal is output to the locking / unlocking control unit 4 and unlocked. This is because an adult other than the driver may open the door from the outside in order to lower the child, even if the door is near the seat where the child is boarding.

  Therefore, when the door 2/3 of the vehicle 1 is in the unlocked state and the position determination unit 54 determines that the portable device 60 is in the vehicle 1, the first interior corresponding to the driver's seat door 2 is provided. When the knob opening operation input unit 51 or the outer knob opening operation input unit 53 of any door receives the opening operation signal, the unlocking signal output unit 55 opens the door on which the opening operation indicated by the unlocking signal has been performed. 2 or the unlocking control unit 4 of the door 3 outputs an unlocking signal. When the second inner knob opening operation input unit 52 corresponding to the passenger door 3 receives the opening operation signal, the unlocking signal output unit 55 receives the opening operation signal indicated by the opening operation signal. No unlocking signal is output to the locking / unlocking control unit 4. That is, the child lock system 100 enables the child lock for the opening operation of the inner knob. FIG. 3A shows such a state. When the portable device 60 is in the vehicle 1, all child locks of the passenger seat door 3 other than the driver's seat door 2 are valid.

  As described above, the child lock mechanism that electrically controls the locking and unlocking of the door and the portable device position determination mechanism in the passive entry system, and the child lock function is controlled by the position of the portable device, further improving convenience A child lock system can be provided.

  If the position determination unit 54 determines in S102 that the portable device 60 is not in the room, the position determination unit 54 checks whether or not the portable device 60 is on the driver's seat side of the vehicle 1 in S106. When the position determination unit 54 determines that the portable device 60 is on the driver's seat side, the unlock signal output unit 55 is opened by the inner knob 31 of the driver's seat side passenger seat door 3 (second door 3) in S108. When the operation is performed, an unlock signal is output to the door lock / unlock control unit 4 of the door that has been opened, and unlocked. This is because when the vehicle stops and the person holding the portable device 60 that is the driver is outside the vehicle on the driver's seat side and the child opens the door from the inside of the vehicle, the person holding the portable device 60 drives the vehicle. This is because it is considered that sufficient attention can be paid to pedestrians and oncoming vehicles on the seat side, so there is no problem even if the child lock is disabled.

  On the other hand, even if the opening operation is performed with the inner knob 31 of the passenger seat door 3 on the passenger seat side, the unlocking signal is not output to the locking / unlocking control unit 4 of the door on which the opening operation has been performed. Do not lock. This is because there is a high possibility that there is no driver on the passenger seat side opposite to the side where the portable device 60 is located, and it may be difficult to pay sufficient attention to pedestrians, etc. Sometimes it is dangerous for a child to open the door alone, so the child lock should be enabled.

  FIG. 3B shows such a state. When the portable device 60 is outside the driver's seat side of the vehicle 1, the child lock of the driver's side passenger seat door 3 is disabled, and the passenger's side passenger seat door 3's child lock is enabled.

  Even when the door 2/3 of the vehicle 1 is unlocked and the position determination unit 54 determines that the portable device 60 is outside the vehicle, the first inner knob opening operation input unit corresponding to the driver's seat door 2 is used. When the outer knob opening operation input unit 53 of 51 or any one of the doors receives the opening operation signal, the unlocking signal output unit 55 unlocks the door 2 or the door 3 on which the opening operation indicated by the unlocking signal is performed. An unlock signal is output to the lock control unit 4. In particular, it is considered that there is no safety problem.

  If the position determination unit 54 determines that the portable device 60 is not on the driver's seat side in S106, the position determination unit 54 checks whether or not the portable device 60 is on the passenger seat side of the vehicle 1 in S110. When the position determination unit 54 determines that the portable device 60 is on the passenger seat side, the unlock signal output unit 55 is opened with the inner knob 31 of the passenger seat door 3 (second door 3) on the passenger seat side in S112. When the operation is performed, an unlock signal is output to the door lock / unlock control unit 4 of the door that has been opened, and unlocked. This is because even if the vehicle is stopped and the person who mainly holds the portable device 60 as the driver is outside the vehicle on the passenger seat side and the child operates the inner knob to open the door, This is because it is considered that the holding person can pay sufficient attention to children, pedestrians on the passenger side, etc., so there is no problem even if the child lock is disabled.

  On the other hand, even if the opening operation is performed with the inner knob 31 of the passenger seat door 3 on the driver's seat side, the unlocking signal is not output to the unlocking control unit 4 of the door that has been opened, and the unlocking signal is not output. Do not lock. This is because there is a high possibility that there is no driver on the driver seat side opposite to the side where the portable device 60 is located, and it may be difficult to pay sufficient attention to pedestrians and oncoming vehicles. Because it is dangerous for a child to open the door alone at such times, child lock should be enabled.

  FIG. 3C shows such a state. When the portable device 60 is outside the passenger seat side of the vehicle 1, the child lock of the passenger seat door 3 on the passenger seat side is disabled, and the child lock of the passenger seat door 3 on the driver seat side is enabled. If the position determination unit 54 determines in S110 that the portable device 60 is not on the passenger seat side of the vehicle 1, the position determination unit 54 determines that the portable device 60 is not in the vicinity of the vehicle 1 in the range where the LF radio wave reaches, and the child The lock system 100 does nothing and ends the process.

  Therefore, when the position determination unit 54 determines that the portable device 60 is outside the vehicle 1, the second inner knob opening operation input unit 52 corresponding to the second door 3 on the side where the portable device 60 is located is provided. When receiving the opening operation signal, the unlocking signal output unit 55 outputs the unlocking signal to the locking / unlocking control unit 4 of the door on which the opening operation has been performed. When the second inner knob opening operation input unit 52 corresponding to the second door 3 on the side opposite to the side where the portable device 60 is located receives an opening operation signal, the unlocking signal output unit 55 performs the opening operation. The unlocking signal is not output to the unlocking control unit 4 of the closed door. When the position determination unit 54 determines that the portable device 60 is outside the vehicle 1, the first inner knob opening operation input unit 51 or the outer knob opening operation input unit 53 receives an opening operation signal. The unlocking signal output unit 55 outputs an unlocking signal to the unlocking control unit 4 of the door that has been opened.

  According to this, when the opening operation is performed at the door opposite to the side where the portable device 60 is located, the child lock is made effective so that even if the vehicle is stopped, the child can It is possible to provide a child lock system that can prevent an accident from occurring with a pedestrian or an oncoming vehicle.

  In this embodiment, one outdoor LF antenna is provided on the driver's seat side and one on the passenger seat side. However, the present invention is not limited to this. For example, a plurality of outdoor LF antennas are provided near the passenger seat and the rear seat. Also good. Then, as shown in FIG. 3D, for example, it can be determined that the portable device 60 is located on the passenger seat side and is located behind the rear seat. In this case, only the door closest to the portable device 60 can be determined. It is preferable because child lock can be disabled. Since the child lock of only the nearest door that an adult exists can be disabled, a child lock system with higher safety can be provided. The child lock function may be provided for each door or only for the door of the rear seat.

  FIG. 4 shows the relationship between the opening operation of the inner knob / outer knob and the action of the child lock when the door is locked and unlocked. In the first place, when the door itself is locked, the door does not open for security and safety reasons, regardless of whether the child lock is valid or invalid. Therefore, the child lock system 100 does not function when the door itself is in a locked state.

  On the other hand, the child lock system 100 functions when the door itself is unlocked. That is, when child lock is enabled, the door does not open even when the inner knob is operated, but when the outer knob is operated, the door opens. In addition, when the child lock is disabled, the door opens regardless of whether the inner knob or the outer knob is operated.

  Note that a switch is preferably provided on the portable device 60 side or the vehicle 1 side in order to set whether the child lock is valid or invalid. In the present embodiment, as shown in FIG. 1, the portable device 60 includes a child lock setting switch 61. When the second inner knob opening operation input unit 52 receives an opening operation signal from the inner knob 31 of the passenger door 3, the child lock setting switch 61 allows the unlocking signal output unit 55 to unlock the passenger door 3. The fact that the unlock signal is not output to the lock control unit 4 is validated or invalidated. According to this, the convenience can be further improved by providing the switch for enabling / disabling the child lock function.

<Modification of the first embodiment>
FIG. 5 is a block diagram showing a child lock system 100A according to a modification of the present embodiment. In order to avoid duplication, differences from the above embodiment will be described. The child lock system 100A further includes an opening signal output unit 56 that outputs an opening command signal to the door opening / closing control unit 41 for automatically opening / closing all or part of the second door 3A.

  When the position determination unit 54 determines that the portable device 60 is in the vehicle 1 </ b> A, when the second inner knob opening operation input unit 52 receives the opening operation signal, the unlock signal output unit 55. The opening signal output unit 56 does not output an unlocking signal and an opening command signal to the door unlocking / unlocking control unit 4 and the door opening / closing control unit 41 that have been opened. According to this, even in the case of an automatic door, a child lock system with improved convenience and safety can be provided.

  In the case of a vehicle equipped with an automatic door that automatically opens and closes by operating a door knob or a dedicated button, if the child lock function is disabled, the door is unlocked and automatically opened, and the child lock is activated. If the function is effective, the door can be unlocked and not automatically opened.
