Description

  The present invention relates to a smart keyless device for a vehicle that enables various operations such as unlocking a door by an occupant when ID authentication is established with a portable transceiver carried by the occupant.

  Conventionally, when an ID signal from a portable transceiver is received by an in-vehicle device and authentication of an ID code included in the ID signal is obtained, unlocking of a vehicle door or starting of an engine is permitted. Smart keyless devices are known.

  Specifically, as disclosed in, for example, Patent Document 1, the smart keyless device is portable when a request signal is transmitted from an in-vehicle transmitter when a passenger unlocks the door or starts an engine. An ID signal including an ID code is transmitted from the transmitter / receiver, and ID authentication is performed by the smart keyless control unit of the in-vehicle device that has received the ID signal. If the ID authentication is established, that is, if the ID code in the ID signal matches the ID code registered in the smart keyless control unit, the smart keyless control unit can unlock the door or start the engine. A permission signal is output, and the door is unlocked and the engine is started according to the operation of the occupant.

  On the other hand, if ID authentication cannot be obtained within a predetermined time after the transmission of the request signal, the smart keyless control unit does not permit unlocking the door or starting the engine, and therefore does not have a portable transceiver. A third party cannot enter the vehicle compartment or start the engine.

  However, in the smart keyless device as described above, when a passenger forgets to place the portable transceiver in the vehicle interior, a third party who has entered the vehicle interior can easily start the engine. When the door is locked, a request signal is sent to the passenger compartment to determine whether there is a misplaced portable transceiver. If there is misplacement, perform misplacement control such as prohibition of engine start. Can be considered.

  Conventionally, in a keyless entry system for a vehicle in which a door lock or door unlock can be performed by wirelessly transmitting a lock signal or unlock signal from a portable transmitter, the lock signal or unlock signal is transmitted. In order to do this, there is also known a switch that can be opened and closed on the driver's seat side or on the passenger seat side by a switch provided in the portable transmitter.

  Specifically, for example, as disclosed in Patent Document 2, after an operator operates a switch of a portable transmitter to transmit a lock signal or an unlock signal, the switch is continued for a predetermined time. When the button is kept pressed, a window closing signal or an opening signal is transmitted, and the vehicle-mounted device that receives the signal performs the opening / closing operation of the window until a new operation signal is received. This makes it possible to close a window that has been forgotten to close after getting off, or to open the window before boarding and quickly ventilate the passenger compartment.

In Patent Document 2, after a window open signal or a close signal is transmitted, the window continues to operate automatically until one of the switches provided in the portable transmitter is pressed. In addition to this, the window closing operation is performed only when the lock switch is pressed, and the window closing operation is stopped when the finger is released from the lock switch. It is also conceivable to prevent pinching by.

  By the way, in the smart keyless device in which the misplacement control is performed as in the former conventional example, the opening / closing operation of the window by the portable transceiver can be performed from the outside like the keyless entry system in the latter conventional example. Then, when trying to close the window immediately after the door lock, there may be a problem that the operation of the window is interrupted.

  That is, after the door is locked, a request signal is transmitted from the in-vehicle transmitter to check whether there is a portable transceiver that has been misplaced in the vehicle interior. An ID signal is transmitted from the transceiver. At this time, when a window closing signal is transmitted from a portable transceiver outside the vehicle that has performed the door lock operation, the frequency of the window closing signal is substantially the same as the frequency of the request signal, and thus the signals are mutually connected. This is because there is a possibility that any signal will not be normally received on the in-vehicle device side due to interference.

  In particular, the portable transceiver that is left behind in the vehicle interior is closer to the in-vehicle receiver, and there are no obstacles such as the body frame between the in-vehicle receiver and the transmission intensity is higher than that of the portable transceiver outside the vehicle. It is highly likely that the window closing signal from the portable transceiver outside the vehicle will not be received normally, and if that happens, the window will not close or the operation will be interrupted, causing the operator to feel uncomfortable. Will give.

  The present invention has been made in view of such a point, and an object of the present invention is to enable remote operation of a window by a portable transceiver and to prevent the portable transceiver from being left behind in the vehicle interior. In a smart keyless device for vehicles that performs misplacement control, the window closing signal from the portable transceiver outside the vehicle interferes with the ID signal from the portable transceiver that is misplaced inside the vehicle, and the window closing operation is normal. It is to prevent things from being done.

  In order to achieve the above object, in the smart keyless device for a vehicle according to the first invention, the transmission timing of the ID signal transmitted from the portable transceiver when confirming that the portable transceiver is left in the passenger compartment is confirmed. However, it was made not to overlap with the reception timing of the window closing signal transmitted from the portable transceiver outside the vehicle.

  That is, the invention of claim 1 is a vehicle-mounted transmitter that wirelessly transmits a request signal toward a portable transceiver carried by a passenger, and an ID signal that is wirelessly transmitted from the portable transceiver in response to the request signal. When at least the vehicle door unlock operation is performed by the vehicle-mounted receiver and the occupant, the vehicle-mounted transmitter transmits a request signal and is transmitted from the portable transceiver according to the request signal. The vehicle-mounted smart keyless device includes: a control unit that receives the ID signal received by the in-vehicle receiver and permits the door unlocking when the ID authentication is established.

  The portable transceiver can transmit a lock signal for locking the door of the vehicle, and can transmit a window close signal for closing the window of the vehicle after transmitting the lock signal. When the on-vehicle receiver receives the lock signal from the first portable transceiver, the control means causes the on-vehicle transmitter to transmit a request signal into the vehicle interior, and in response to the request signal, the vehicle interior A misplacement determination unit that receives an ID signal transmitted from a second portable transceiver located in the vehicle and determines that it has been misplaced in the passenger compartment when ID authentication is established; and the first portable transceiver A window control unit for closing the window of the vehicle when a window closing signal transmitted from the machine is received, and a lock signal received by the in-vehicle receiver A timing prediction unit that predicts the reception timing of the window closing signal, and the misplacement determination unit is configured such that the transmission timing of the ID signal by the second portable transceiver is the reception timing of the window closing signal. It is assumed that the vehicle-mounted transmitter is configured to transmit a request signal differently.

  With this configuration, when the door lock is performed by the lock signal transmitted from the first portable transceiver, the request signal is transmitted from the in-vehicle transmitter toward the vehicle interior. When the ID signal is transmitted from the transceiver, it is determined whether the authentication of the ID has been established, the portable transceiver is left behind, and the second portable transceiver is left behind in the vehicle interior. If it is determined, misplacement control such as disabling the portable transceiver or issuing an alarm can be performed.

  Here, the lock signal is transmitted by a switch operation in the first portable transceiver, and after the transmission, if the switch operation of the portable transceiver is continued, a window closing signal is transmitted from the portable transceiver. It has come to be. Therefore, it is possible to predict the reception timing of the window closing signal at the in-vehicle receiver based on the lock signal, and the ID signal transmitted from the second portable transceiver with respect to the predicted reception timing. By transmitting the request signal so as not to overlap with the transmission timing of, it is possible to prevent the window closing signal and the ID signal from interfering with each other.

  Accordingly, the window closing signal transmitted from the first portable transceiver is reliably received by the in-vehicle receiver, and the window closing operation is normally performed. Therefore, the operator feels uncomfortable due to the interruption of the window closing operation or the like. Can be prevented.

  In the second invention, the transmission timing of the ID signal transmitted from the second portable transceiver located in the passenger compartment overlaps with the reception timing of the window closing signal transmitted from the first portable transceiver. In some cases, the transmission strength of the ID signal is reduced.

  That is, the invention of claim 2 is similar to the first invention, in-vehicle transmitter for wirelessly transmitting a request signal to a portable transceiver carried by a passenger, and the portable transceiver according to the request signal. A vehicle-mounted receiver that receives an ID signal transmitted wirelessly from the vehicle, and at least when a vehicle door unlock operation is performed by the occupant, the vehicle-mounted transmitter transmits a request signal, and responds to the request signal. A vehicle smart keyless device comprising: a control means for receiving an ID signal transmitted from a portable transceiver by the in-vehicle receiver and allowing the door to be unlocked when authentication of the ID is established. And

  The portable transceiver can transmit a lock signal for locking the door of the vehicle, and can transmit a window close signal for closing the window of the vehicle after transmitting the lock signal. When the on-vehicle receiver receives the lock signal from the first portable transceiver, the control means causes the on-vehicle transmitter to transmit a request signal into the vehicle interior, and in response to the request signal, the vehicle interior A misplacement determination unit that receives an ID signal transmitted from a second portable transceiver located in the vehicle and determines that it has been misplaced in the passenger compartment when ID authentication is established; and the first portable transceiver A window control unit for closing the window of the vehicle when a window closing signal transmitted from the machine is received, and a lock signal received by the in-vehicle receiver A timing prediction unit that predicts the reception timing of the window closing signal, and the misplacement determination unit is transmitted from the second portable transceiver at substantially the same timing as the reception timing of the window closing signal. It is assumed that the transmission strength of the ID signal is reduced.

  With this configuration, when the window closing operation is performed by the first portable transceiver following the door lock operation by the first portable transceiver, the first portable is predicted by the timing prediction unit. If the reception timing of the window closing signal from the transceiver and the transmission timing of the ID signal transmitted from the portable transceiver when there is a portable transceiver left in the passenger compartment, the ID signal The window closing signal can be reliably received by the in-vehicle receiver by reducing the transmission intensity of the signal, and the operator can be prevented from feeling uncomfortable due to the interruption of the window closing operation.

  In the configuration according to the first and second inventions described above, the control means includes a portable transceiver confirmation unit that authenticates an ID of a portable transceiver that is located in the passenger compartment before receiving the lock signal; For a portable transceiver that has not been authenticated within a predetermined time after receiving the lock signal, change of the transmission timing of the ID signal and a decrease in transmission strength by the misplacement determination unit are prohibited. 1 forbidden part (invention of claim 3), and when the vehicle-mounted receiver does not receive the window closing signal within the time predicted by the timing prediction part after receiving the lock signal In addition, a second prohibition unit that prohibits a change in the transmission timing of the ID signal and a decrease in transmission intensity by the misplacement determination unit may be provided (invention of claim 4). Here, the predetermined time retroactively from when the lock signal is received means a time during which the portable transceiver is unlikely to be brought into the vehicle compartment or taken out of the vehicle.

  Thereby, ID authentication is established if it is present in the vehicle interior, ie, a portable transceiver that does not establish ID authentication within a predetermined time retroactively from the reception of the lock signal, but is present in the vehicle interior. IDs are not wasted for portable transceivers that are not in the vehicle or that are present in the passenger compartment but for which authentication of ID is not established, because no ID signal is transmitted from those portable transceivers. By prohibiting changing the signal transmission timing or lowering the transmission intensity, the in-vehicle receiver can quickly receive the ID signal from the portable transmitter / receiver for which ID authentication has been established. Thus, the time required for confirmation of misplacement can be shortened.

  In other words, by changing the transmission timing and the transmission intensity only for portable transceivers that may transmit ID signals, while effectively preventing the window closing operation from being interrupted, As a whole, the time for confirmation of misplacement can be shortened.

  In addition, when the window closing signal is not received within the expected time after receiving the lock signal, it is not necessary to consider interference with the window closing signal. By avoiding the decrease, it is possible to shorten the misplacement confirmation time while ensuring the detection accuracy of the portable transceiver that is misplaced in the vehicle interior.

  In the third invention, the transmission timing of the ID signal transmitted from the second portable transceiver located in the vehicle interior overlaps with the reception timing of the window closing signal transmitted from the first portable transceiver. The window closing operation is continued even when the window closing signal continuously received is not received due to interference with the ID signal.

  That is, the invention of claim 5 is similar to the first and second inventions, in-vehicle transmitter that wirelessly transmits a request signal to a portable transceiver carried by a passenger, and the portable device according to the request signal. An in-vehicle receiver that receives an ID signal wirelessly transmitted from a transceiver for transmission, and when the occupant performs at least an unlocking operation of a vehicle door, the request signal is transmitted to the in-vehicle transmitter, and the request is transmitted. A vehicle smart keyless comprising: control means for receiving an ID signal transmitted from a portable transceiver in response to the signal by the in-vehicle receiver and permitting the door to be unlocked when the authentication of the ID is established Intended for equipment.

The portable transceiver can transmit a lock signal for locking the door of the vehicle, and can transmit a window close signal for closing the window of the vehicle after transmitting the lock signal. When the on-vehicle receiver receives the lock signal from the first portable transceiver, the control means causes the on-vehicle transmitter to transmit a request signal into the vehicle interior, and in response to the request signal, the vehicle interior A misplacement determination unit that receives an ID signal transmitted from a second portable transceiver located in the vehicle and determines that it has been misplaced in the passenger compartment when ID authentication is established; and the first portable transceiver A window control unit that closes the window of the vehicle when a window closing signal transmitted from the machine is received, and the window control unit includes the on-vehicle receiver. When the window closing signal is continuously received, the window closing operation is continued even when the window closing signal is not received when the ID signal transmitted from the second portable transceiver is received. According to this configuration, when the window closing operation is performed by the first portable transceiver following the door lock operation by the first portable transceiver, the timing prediction unit predicts. The reception timing of the window closing signal from the first portable transceiver overlaps with the transmission timing of the ID signal transmitted from the portable transceiver when there is a portable transceiver forgotten in the vehicle interior. Even if the ID signal is received and the continuously received window closing signal is not received, the window closing operation is continued. Be to, it is possible to prevent the discomfort to the operator by the interruption or the like of the window closing operation.

  In the above-described configuration, the window closing signal is composed of a pulse signal transmitted intermittently at a predetermined interval, and the control means continues the window closing operation by the window control unit without receiving the window closing signal pulse. When the operation is performed, it is preferable to include a pulse control unit that causes the first portable transceiver to transmit the next pulse signal at an interval shorter than the predetermined interval. ). Here, the predetermined interval is usually a timing at which a window closing signal is transmitted, and is set to an interval of 0.5 seconds, for example.

  In this way, when the window closing operation is continued without receiving the window closing signal pulse signal from the first portable transceiver, the operator can close the window by transmitting the next pulse signal early. Since it is possible to quickly confirm whether or not there is an intention to continue the operation, it is possible to prevent the window from operating against the operator's intention, and the operator does not feel uncomfortable.

  As described above, according to the smart keyless device for vehicles according to the first invention, the second portable transmission / reception located in the vehicle interior with respect to the reception timing of the window closing signal transmitted from the first portable transceiver. The window closing signal interferes with the ID signal by changing the transmission timing of the request signal transmitted to the second portable transceiver so that the transmission timing of the ID signal transmitted from the machine does not overlap, It is possible to prevent the window closing operation from being interrupted. This can prevent the operator from feeling uncomfortable during the window closing operation.

  According to the second invention, when it is predicted that the window closing signal from the outside of the vehicle interferes with the ID signal from the passenger compartment, the window closing signal is surely reduced by reducing the transmission intensity of the ID signal. Since the signal is received by the in-vehicle receiver, it is possible to prevent the operator from feeling uncomfortable due to the interruption of the window closing operation.

  In the first and second inventions, the ID signal transmission strength and the ID signal transmission strength as described above can be changed for a portable transceiver that has not been authenticated before the door is locked. By avoiding such a decrease, it is possible to shorten the time for confirmation of misplacement as a whole. Further, even when the window closing signal is not received, the same effect can be obtained by not changing the transmission timing of the ID signal or reducing the transmission intensity as described above.

  According to the third invention, when the ID signal is received from the second portable transceiver located in the vehicle interior, the window closing signal received from the first portable transceiver is not received. However, since the window closing operation is not interrupted by continuing the window closing operation, the operator does not feel uncomfortable. When the window closing signal is composed of pulse signals transmitted at a predetermined interval, when the window closing operation is continued without receiving the window closing signal pulse signal, the first portable transceiver is connected to the first portable transceiver. By making the transmission timing of the pulse signal earlier, it is possible to prevent the window from performing an operation different from the intention of the operator, thereby preventing the operator from feeling uncomfortable.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the following description of the preferred embodiment is merely illustrative in nature and is not intended to limit the present invention, its application, or its use.

(Embodiment 1)
FIG. 1 shows an overall configuration of a smart keyless system A according to Embodiment 1 of the present invention. This system A includes two portable devices 2 and 3 (portable transceivers) as portable transceivers carried by the occupant and an in-vehicle device 4 (smart keyless device for vehicles) mounted on the vehicle 1. FIG. 2 is a perspective view of the vehicle 1 on which the in-vehicle device 4 is mounted. In FIG. 2, a driver's seat side door 11a is provided on the right side of the vehicle 1, while a passenger seat side door 11b is provided on the left side of the vehicle, and window glasses 12a and 12b are provided on the doors 11a and 11b, respectively. (Window) is provided.

  Although the portable devices 2 and 3 have the same configuration, in the following description, a device located outside the vehicle is referred to as a portable device 2, and a device located inside the vehicle interior is referred to as a portable device 3. The portable devices 2 and 3 have portable device control units 20 and 30 each composed of a CPU. The portable device control units 20 and 30 are respectively provided with receiving antennas 21 and 31 for receiving a request signal r from an in-vehicle device 4 to be described later, an ID signal i including an ID code (ID, authentication code), a door lock or Transmitting antennas 22 and 32 for wirelessly transmitting door opening and closing signals P and S for opening and closing operation of the window glass 12a and 12b are connected so as to be able to exchange signals. Has been. That is, for example, in the portable device 2, when the receiving antenna 21 receives the request signal r from the in-vehicle device 4, the portable device control unit 20 receives the request signal r and the ID signal i including the ID code is transmitted to the transmitting antenna. 22 to transmit from. The ID signal i, the lock signal L, the unlock signal U, and the window open / close signals P and S are all signals in the same frequency band.

  The portable device control units 20 and 30 include batteries 23 and 33 for supplying power, memories 24 and 34 for storing the ID code and the like, and a switch for locking the door, respectively. Are connected to unlock switches 26 and 36 for releasing the door lock, and the doors are locked by the lock switches 25 and 35 and the unlock switches 26 and 36. A keyless entry system that can be operated remotely is configured.

  In addition, as will be described in detail later, the lock switches 25 and 35 are continuously pressed even after transmission of the lock signal, thereby closing at least one of the window glasses 12a and 12b on the driver seat side and the passenger seat side. While also serving as a window closing switch, the unlock switches 26 and 36 continue to be pressed even after the door lock is released, thereby opening the windows 12a and 12b on at least one of the driver seat side and the passenger seat side. It is configured to double as an open switch.

  The in-vehicle device 4 is provided with a smart keyless control unit 40 having a CPU as control means. The smart keyless control unit 40 includes an indoor transmission antenna 41 and an outdoor transmission antenna 42 (on-vehicle transmitter) for transmitting a request signal r to the portable devices 2 and 3, and an ID signal from the portable devices 2 and 3. The vehicle-mounted receiving antenna 43 (vehicle-mounted receiver) for receiving i and the like and the memory 44 for storing the ID codes of the portable devices 2 and 3 are connected so as to be able to send and receive signals. When the in-vehicle receiving antenna 43 receives the ID signal i transmitted from the portable device 2 or 3 in response to the request signal r, the ID code included in the ID signal i is registered in the memory 44. If it is registered, the ID code is authenticated, and various operations (specifically, refer to each control described later) in the vehicle 1 are made possible.

  As shown in FIG. 2, the outdoor transmission antennas 42 are provided at three locations on the driver side and passenger side doors 11a and 11b, and the tailgate 11c (in the case of a sedan type, on the vehicle interior side of the rear end panel). The driver-side transmission antenna 42a, the passenger-side transmission antenna 42b, and the tailgate transmission antenna 42c, while the indoor transmission antenna 41 is located on the vehicle front side of the instrument panel 13 located in front of the passenger seat and the vehicle. It consists of a front transmission antenna 41a and a rear transmission antenna 41b provided at two locations on the vehicle rear side of the rear seat. Of the outdoor transmission antennas 42, the driver's seat side transmission antenna 42a and the passenger seat side transmission antenna 42b are configured to transmit radio waves also into the passenger compartment. The in-vehicle receiving antenna 43 is provided on the header 14 so as to cover the entire interior of the vehicle interior.

  By arranging the transmitting antennas 41a to 41c, 42a, and 42b as described above, it is possible to grasp where the portable devices 2 and 3 are located inside and outside the vehicle interior.

  That is, the transmission antennas 41a to 41c, 42a, and 42b transmit the request signal r to a substantially spherical range around the transmission antennas 41a to 41c, 42a, and 42b, respectively, and the ranges overlap. It is configured. The request signal r is transmitted sequentially from the transmitting antennas 41a to 41c, 42a, 42b, and the ID signal i transmitted from the portable devices 2 and 3 is transmitted to the in-vehicle receiving antenna 43. Is to be received by.

  In the above configuration, the position of the portable device 2 or 3 can be estimated by detecting the response timing of the ID signal i transmitted from the portable device 2 or 3 with respect to the request signal r. For example, when the ID signal i returned from the portable devices 2 and 3 is received by the in-vehicle receiving antenna 43 only for the request signal r of either the driver side or passenger side transmitting antennas 42a and 42b, The portable devices 2 and 3 can be determined to exist outside the vehicle near the driver's seat side door 11a or outside the passenger's seat side door 11b, and request signals for both the driver's seat side and passenger seat side transmission antennas 42a and 42b. When the ID signal i returned from the portable devices 2 and 3 is received by the in-vehicle receiving antenna 43 with respect to r, it can be determined that the portable devices 2 and 3 are located in the driver's seat or the passenger seat in the passenger compartment. . Further, when the in-vehicle receiving antenna 43 receives the ID signal i returned from the portable devices 2 and 3 in response to the request signal r from the front transmission antenna 41a, the portable devices 2 and 3 are placed in the passenger seat. It is determined that it is located.

  Further, the smart keyless control unit 40 includes door request switches 45 and 45 and door key cylinders 46 and 46 provided on the door knobs of the driver side and passenger side doors 11a and 11b, and the doors 11a and 11b. Window drive for moving the door glass 11a and 11b up and down, and door lock actuators 47 and 47 for switching the doors 11a and 11b to a locked state or an unlocked state. Motors 48 and 48 are connected. Thus, for example, when a user carrying the portable device 2 in a door-locked state presses the door request switch 45, the request signal r is transmitted from the transmission antennas 41 and 42, and the portable device is correspondingly transmitted. The so-called smart entry system is configured in which the door lock is released by the door lock actuator 47 after the ID signal i transmitted from the second transmission antenna 22 is received by the in-vehicle reception antenna 43 and the ID code is authenticated. It has come to be.

  The door lock or door lock release is not only a method using the smart entry system as described above, but also a door lock or door lock release by inserting a key into the door key cylinder 46 and turning it, or the portable device. The door lock actuator 47 may be remotely operated by pressing the second and third lock switches 25 and 35 and the unlock switches 26 and 36 to perform door lock or door lock release. As described above, when the door lock or the door unlock is performed using the lock switches 25 and 35 or the unlock switches 26 and 36 of the portable devices 2 and 3, the lock switches 25 and 35 are kept constant. When the time is pressed, the window drive motor 48 is operated to close the window glasses 12a and 12b, while the unlock switches 26 and 36 are continuously pressed for a predetermined time to operate the window drive motor 48. Thus, the window glass 12a, 12b is opened.

  Further, the smart keyless control unit 40 is provided in the vicinity of the steering wheel, and an ignition knob 49 for starting the engine of the vehicle 1 and an engine control unit 50 (starting the engine by operating the ignition knob 49) ECU). As a result, when the user who has the portable device 2 gets on the vehicle 1 and the ID code of the portable device 2 is authenticated, the user operates the ignition knob 49 so that the smart keyless control is performed. A start permission signal is output from the unit 40 to the engine control unit 50, and the engine control unit 50 starts the engine.

  Here, the ignition knob 49 is configured to rotate from the accessory OFF position to each of the accessory ON, ignition ON, and ignition START positions. Is output to the smart keyless control unit 40.

  Further, the smart keyless control unit 40 includes an alarm lamp 51 and a buzzer 52 as notification means for notifying the occupant when it is determined that the portable device 3 has been left behind in the vehicle interior as will be described later. Thus, it is possible to prevent misplacement of the portable device 3 in the passenger compartment.

  The smart keyless control unit 40 detects that the engine speed detection sensor 53 that detects the engine speed, the vehicle speed detection sensor 54 that detects the vehicle speed of the vehicle 1, and the doors 11a and 11b are in an open state. Door opening detection sensors 55 and 55, and door lock detection sensors 56 and 56 for detecting that the doors 11a and 11b of the vehicle are locked or unlocked are also connected.

  In the smart keyless control unit 40 having the above-described configuration, the following controls are performed.

  The smart keyless control unit 40 is configured to perform door lock control. In this door lock control, the doors 11a and 11b are unlocked or locked without inserting a key into the key cylinders 46 and 46 of the doors 11a and 11b, and the switches 25 and 26 of the portable device 2 are controlled. When the door lock or the door lock is released by a pressing operation, the windows 25a and 12b are opened and closed by continuously pressing the switches 25 and 26 for a predetermined time.

  That is, when the driver of the portable device 2 presses the door request switch 45 when the engine of the vehicle 1 is stopped, the request signal r is transmitted from the transmission antennas 41 and 42 of the vehicle 1. When the in-vehicle receiving antenna 43 receives the ID signal i returned from the portable device 2 that has received the request signal r, the ID code included in the ID signal i is verified. When the authentication of the ID code is obtained, the door 11a, 11b is unlocked when the door is locked, and the door is locked when the door 11a is unlocked. The door lock detection sensor 56 detects the lock or unlock state of the doors 11a and 11b. The doors 11 a and 11 b are unlocked or locked when the smart keyless control unit 40 outputs an unlock signal or a lock signal to each door lock actuator 47.

  The above-described control is performed not only by the operation of the door request switch 45 but also by the operation of the lock switch 25 and the unlock switch 26 provided in the portable device 2. That is, for example, when the lock switch 25 is pressed, the lock signal L and the ID signal i of the portable device 2 are transmitted from the transmission antenna 22 of the portable device 2, and the smart keyless control unit 40 of the in-vehicle device 4 that has received the lock signal L. Then, the ID code is verified, and if authentication is obtained, the door is locked.

  When the door lock control is performed by operating the switches 25 and 26 of the portable device 2 as described above, the window closing signal S or the window is displayed from the portable device 2 by continuously pressing the switches 25 and 26. An open signal P is transmitted. When the in-vehicle device 4 receives these signals P and S, the smart keyless control unit 40 drives the window drive motor 48 so as to open and close the window glasses 12a and 12b on the driver side or the passenger side. It has become. Thereby, for example, if the window glass 12a on the driver's seat side is open when the door is locked, the window glass 12a can be closed by continuously pressing the lock switch 25 of the portable device 2, Convenience can be improved. On the other hand, if the window glass 12a on the driver's seat side is closed when the door is unlocked, the driver's side window glass 12a can be opened by continuously pressing the unlock switch 26 of the portable device 2. The vehicle interior can be quickly ventilated.

  Here, when the window glasses 12a and 12b are closed, the window closing signal S is intermittently transmitted in a pulse form from the portable device 2, and the operator stops the operation of the switches 25 and 26, that is, the window. When the closing signal S is not received by the vehicle-mounted device 4, the closing operation of the window glasses 12a and 12b is stopped with good responsiveness. Thereby, the pinching by the closing operation | movement of the window glass 12a, 12b can be prevented, and safety can be improved. On the other hand, when the window glasses 12a and 12b are opened, once the window opening signal P from the portable device 2 is received, the window glasses 12a and 12b are opened until the window glasses 12a and 12b are fully opened. ing. In this case, the opening operation of the window glasses 12a and 12b is stopped by re-operating one of the switches 25 and 26 of the portable device 2.

  Although details will be described later, after the door is locked, it is checked whether the portable device 3 is left behind in the vehicle interior. Has also been made.

  The smart keyless control unit 40 is configured to perform steering lock release control. In a state where the vehicle is parked, the ignition knob 49 is positioned at the accessory OFF, and the steering is locked. Steering lock release control is control that releases the steering lock state and enables operation. That is, when a user who gets in the vehicle presses the ignition knob 49, the request signal r is transmitted from the transmission antennas 41 and 42 toward the vehicle interior. The ID signal i transmitted from the portable device 2 in response to the request signal r is received, and the ID code included in the ID signal i is collated. When the authentication of this ID code is obtained, the steering lock is released.

  The smart keyless control unit 40 is configured to perform engine start control that permits the engine control unit 50 to start the engine. The engine start control refers to control for starting the engine by rotating the ignition knob 49 to the ignition START position. That is, when the driver rotates the ignition knob 49 to the ignition START position, the request signal r is transmitted from the transmission antennas 41 and 42. The ID signal i transmitted from the portable device 2 in response to the request signal r is received, and the ID code included in the ID signal i is collated. When authentication of this ID code is obtained, a start permission signal is output to the engine control unit 50, and the engine control unit 50 starts the engine.

  Further, the smart keyless control unit 40, which is a characteristic part of the present invention, confirms whether or not the portable device is left in the passenger compartment after the door is locked by the door lock control described above, and the portable It is configured to perform misplacement control that executes invalidation of the machine. That is, after the door is locked by the operation of the door request switch 45 or the switches 25 and 26 of the portable device, the request signal r (hereinafter also referred to as misplacement confirmation signal) is transmitted from the transmission antennas 41a, 41b, 42a, and 42b to the vehicle interior. Is supposed to send. When the portable device 3 whose ID code is registered in the memory 44 is present in the passenger compartment, the ID signal i is transmitted from the portable device 3 in response to the request signal r. If the authentication is obtained by verifying the ID code, the user is informed by the alarm lamp 51 and the buzzer 52 that the portable device 3 has been left in the passenger compartment, and is located outside the vehicle. The portable device 3 in the passenger compartment is invalidated until the door lock is next released by the portable device 2. This invalidation invalidates a signal (window open / close signal, etc.) transmitted from the portable device 3 in the passenger compartment, and the above-described door lock control, steering lock only by authentication of the ID code of the portable device 3 It means that various controls such as control and engine start control are not performed.

  Here, the ID signal i transmitted from the portable device 3 in the vehicle interior corresponding to the request signal r is a window closing signal transmitted from the portable device 2 located outside the vehicle when the door is locked in the door lock control described above. Since it is the same frequency band as S, the transmission timing of the request signal r transmitted toward the vehicle interior after the door lock is determined so that the ID signal i and the window closing signal S do not interfere with each other. . Specifically, since the window closing signal S is transmitted from the portable device 2 at predetermined time intervals (for example, every 0.5 seconds) after the door is locked, the in-vehicle receiving antenna 43 for the window closing signal S is based on this. Can be estimated. Therefore, the request signal r for transmitting the ID signal i is transmitted at a later timing so that the reception timing does not overlap with the transmission timing of the ID signal i transmitted from the portable device 3 in the vehicle interior. It has become.

  Specifically, in the example of FIG. 3, when the lock signal L is transmitted from the portable device 2 and the door lock is performed in the vehicle-mounted device 4, the smart keyless control unit 40 of the vehicle-mounted device 4 is stored in the memory 44. Request signals r (hereinafter also referred to as misplacement confirmation signals) are stored in the vehicle compartment for the number of portable devices registered in advance (six units A to F in the example shown in the figure). Means a signal for a plurality of portable devices in which ID codes are registered. At this time, since the pulse-like window closing signal S is intermittently transmitted from the portable device 2, the smart keyless control unit 40 estimates the reception timing of the window closing signal S and deviates from the reception timing. As described above, the misplacement confirmation signal B is transmitted after the signal A at a slightly later timing. Thus, even when an ID signal i (hereinafter also referred to as ID signal B) is transmitted from the portable device 3 in the vehicle interior corresponding to the misplacement confirmation signal B, the transmission timing of the ID signal B is set to the portable device 2. Therefore, the window closing signal S is reliably received by the vehicle-mounted device 4 without being affected by the ID signal B. Therefore, when the operator is operating the window closing operation, the window closing operation can be prevented from being interrupted in the middle of the operation, and the operator does not feel uncomfortable.

  In order to confirm the presence of the portable device 3 in the passenger compartment, the ID code is authenticated as described above even before the lock signal L is received, and the ID is received within a predetermined time from the time when the lock signal L is received. Control for shifting the transmission timing of the ID signal i as described above may not be performed on a portable device for which code authentication has not been obtained. In addition, even when there is a portable device with ID code authentication, after receiving the lock signal L, if the window close signal S is not received within the time when the window close signal is expected to be received, Similarly, control that shifts the transmission timing of the ID signal i may not be performed. Here, the predetermined time retroactively from when the lock signal L is received means a time during which the portable transceiver is unlikely to be brought into the vehicle interior or taken out of the vehicle, and the window is closed. The time when the reception of the signal is predicted is a time predicted based on the lock signal L transmitted from the portable device 2. Specifically, the window closing signal is transmitted from the portable device 2 to the lock signal L. This means the time required for the window closing signal S to be received by the in-vehicle receiving antenna 43 after S is transmitted.

  In the above misplacement confirmation signal, signals corresponding to a plurality of portable devices are transmitted, and in order to cover the entire vehicle interior, a plurality of transmission antennas 41a, 41b, 42a, 42b having transmission areas in the vehicle interior are sequentially provided. Since it is transmitted, if the transmission timing of the request signal r is delayed unnecessarily, the time required for confirmation of misplacement becomes longer. Therefore, as described above, when there is no possibility of interference between the ID signal i and the window closing signal S, it is possible to shorten the misplacement confirmation time by not changing the transmission timing of the request signal r. it can.

  Here, as described above, the smart keyless control unit 40 that authenticates the ID code and confirms the presence of the portable device 3 before receiving the lock signal L receives the lock signal L to the portable transceiver confirmation unit. The smart keyless control unit 40 that does not shift the transmission timing of the request signal r for the portable device that has not obtained the ID code authentication within a predetermined time retroactively from the time of When the window closing signal S is not received within a time when reception of the window closing signal is expected after receiving L, the smart keyless control unit 40 that prevents the transmission timing of the request signal r from being shifted is the second. Corresponds to each prohibited section.

  In the portable device control unit 20 and the smart keyless control unit 40 having the above configuration, each control described above is executed according to a flow as shown in FIG. Specifically, as shown in the left side of FIG. 4, when the flow starts on the vehicle-mounted device 4 side, first, door lock control is performed in step S1 to perform door lock or door lock release, and then in step S2, steering is performed. Steering lock control is performed to release the lock. Thereafter, engine start control when starting the engine is performed in step S3, and this flow is started again (return). The portable device 2 side is the same as the above-described flow as shown on the left side of FIG.

  Below, the specific flow of each control shown in FIG. 4 is demonstrated in detail.

<Door lock control>
A flow of door lock control performed by the in-vehicle device 4 and the portable device 2 is shown in FIGS. In the following description, first, the door lock control performed by the in-vehicle device 4 will be described, and then the door lock control performed by the portable device 2 will be described.

−In-vehicle device−
When the flow shown on the left side of FIG. 5 starts, first, in step SA1, it is determined based on the output signal from the engine speed detection sensor 53 whether or not the engine is rotating. When it is determined that the engine is rotating (in the case of YES), the door lock control is not necessary and this flow is ended (END). On the other hand, when it is determined that the engine is not rotating (in the case of NO), the process proceeds to the subsequent step SA2 to perform door lock control such as door lock or door lock release using the smart entry system.

  In step SA2, which proceeds to the case where it is determined in step SA1 that the engine is not rotating (in the case of NO), it is determined whether or not the door request switch 45 has been operated. If it is determined that the door request switch 45 has not been operated (in the case of NO), the process proceeds to step SA11 and subsequent steps to determine whether or not the unlock signal U has been transmitted from the portable device 2 via wireless communication. Do. On the other hand, when it is determined in step SA2 that the door request switch 45 has been operated (in the case of YES), the process proceeds to step SA3, and a request signal r is transmitted to the portable device 2.

  In step SA4, it is determined whether or not the ID signal i is received from the portable device 2 within a predetermined time after the request signal r is transmitted. If it is determined that the ID signal i is not received (NO) In the case), the operation by the door request switch 45 is not allowed, and the process proceeds to step SA11 and subsequent steps. On the other hand, when it is determined that the ID signal i has been received (in the case of YES), the ID code of the received ID signal i is collated, and whether it matches the ID code stored in the memory 44 (authentication) (Step SA5, SA6). The predetermined time in step SA4 is set to a time sufficient to receive the ID signal i transmitted from the portable device 2 by the in-vehicle receiving antenna 43 after transmitting the request signal r to the portable device 2. The

  If the authentication of the ID code included in the ID signal i received from the portable device 2 is not obtained (NO in step SA6), the process proceeds to step SA11 and thereafter, while the authentication is obtained (YES). In the case), in the subsequent step SA7, it is determined whether or not the door is locked based on the output signal from the door lock detection sensor 56. If it is determined in step SA7 that the door is locked (YES), door unlock control is performed in step SA8 to release the door lock, and the process proceeds to step SA11.

  On the other hand, if it is determined in step SA7 that the door is not locked (NO), door lock control is performed in step SA9 to bring the door into a locked state. Thereafter, in step SA10, misplacement countermeasure control described later is performed, and the process proceeds to step SA11 and subsequent steps.

  In Step A11, it is determined whether or not the unlock signal U is received from the portable device 2. If it is determined in step SA11 that the unlock signal U has not been received (in the case of NO), the process proceeds to step SA15 and thereafter, while it is determined that the unlock signal U has been received (in the case of YES). In addition, the ID code of the ID signal i transmitted from the portable device 2 together with the unlock signal U is collated, and it is determined whether the ID code stored in the memory 44 matches with the authentication. (Steps SA12 and SA13). When authentication is not obtained (in the case of NO), the process proceeds to step SA15 and after. On the other hand, when authentication is obtained (in the case of YES), door unlock control is performed in step SA14, and after step SA15. Proceed to

  In step SA15, it is determined whether the window open signal P has been received. If it is determined in step SA15 that the window opening signal P has not been received (in the case of NO), the process proceeds to step SA19 and thereafter, while it is determined that the window opening signal P has been received (in the case of YES). In this case, the ID code of the ID signal i transmitted from the portable device 2 together with the window opening signal P is checked, and it is determined whether or not the ID code is authenticated (steps SA16 and SA17). If authentication is not obtained (in the case of NO), the process proceeds to step SA19 and thereafter. If collation is obtained (in the case of YES), the window drive motor 48 is driven in step SA18 to drive the window glass. Window full open control is performed to open 12a and 12b, and the process proceeds to step SA19 and subsequent steps. In this window full open control, once the window open signal P is received, the window glasses 12a and 12b are fully opened even if the window open signal P is not received continuously or intermittently. The window glasses 12a and 12b are opened.

  In step SA19, it is determined whether or not the lock signal L has been received. If it is determined in step SA19 that the lock signal L has not been received (in the case of NO), the process proceeds to step SA24 and thereafter, whereas if it is determined that the lock signal L has been received (in the case of YES), The ID code of the ID signal i transmitted from the portable device 2 together with the lock signal L is checked, and it is determined whether or not the ID code is authenticated (steps SA20 and SA21). If the authentication is not obtained (in the case of NO), the process proceeds to step SA24 and subsequent steps. On the other hand, if the authentication is obtained (in the case of YES), the door lock control is performed in step SA22 and then the subsequent step SA23. Then, misplacement handling control described later is performed, and the process proceeds to step SA24 and subsequent steps.

  In step SA24, it is determined whether the window closing signal S has been received. If it is determined in step SA24 that the window closing signal S has not been received (in the case of NO), this flow is ended (end), whereas if it is determined that the window closing signal S has been received (YES) In this case, the ID code of the ID signal i transmitted from the portable device 2 together with the window closing signal S is collated, and it is determined whether or not the ID code is authenticated (steps SA25 and SA26). . If the authentication is not obtained (in the case of NO), this flow is terminated (end). On the other hand, if the authentication is obtained (in the case of YES), the window closing control is performed in step SA27. End the flow (end). Note that the window closing control performed in step SA27 is to move the window glasses 12a and 12b upward by a predetermined height in accordance with the window closing signal S. When the person stops transmitting the window closing signal S from the portable device 2, the window closing operation can be stopped with good responsiveness, and safety can be improved. Here, the step SA27 for performing the window closing control corresponds to the window control unit 40a.

-Portable machine-
Next, the operation | movement in the door lock control of the portable device 2 is demonstrated below.

  First, when the door lock control flow shown on the right side of FIG. 5 is started, it is determined whether or not the request signal r is received from the in-vehicle device 4 in step SA1 '. If it is determined in step SA1 ′ that the request signal r has been received (in the case of YES), in the subsequent step SA2 ′, the ID signal i including the ID code is transmitted to the vehicle-mounted device 4, and step SA3. Go to '. On the other hand, if it is determined in step SA1 ′ that the request signal r has not been received (in the case of NO), the process proceeds to step SA3 ′ as it is, that is, whether the door unlocking operation is being performed, that is, the unlock switch. It is determined whether or not 26 is operated. When it is determined that the door unlocking operation is performed (in the case of YES), the unlock signal U is transmitted to the vehicle-mounted device 4 together with the ID signal i (step SA4 ′), while the door unlocking operation is performed. If it is determined that it is not (NO), the process proceeds to Step SA7 ′ described later.

  In step SA5 ′, which proceeds after step SA4 ′, it is determined whether or not the operation of the unlock switch 26 is continued for a predetermined time or more, and the unlock switch 26 is continuously operated. If it is determined (in the case of YES), the process proceeds to step SA6 ′, the window opening signal P is transmitted to the vehicle unit 4 together with the ID signal i, and the process proceeds to step SA7 ′. On the other hand, if it is determined in step SA5 'that the operation of the unlock switch 26 has not been continued for a predetermined time or more (in the case of NO), the process proceeds to step SA7' as it is. The predetermined time is longer than the time from when the unlock switch 26 is pressed until the unlock signal U is transmitted so that the operator's intention to desire the window closing operation can be accurately determined. Set to

  In step SA7 ', it is determined whether the door lock operation has been performed, that is, whether the lock switch 25 has been operated. If it is determined in step SA7 ′ that the door lock operation has been performed (in the case of YES), the process proceeds to the subsequent step SA8 ′ to transmit the lock signal L together with the ID signal i to the vehicle-mounted device 4, while the door lock If it is determined that no operation has been performed (NO), this flow ends (END).

  In step SA9 ′, which proceeds after step SA8 ′, it is determined whether or not the operation of the lock switch 25 is continued for a predetermined time or more, and it is determined that the lock switch 25 is continuously operated. If YES (YES), the process proceeds to step SA10 ′, and the window closing signal S is transmitted to the in-vehicle device 4 together with the ID signal i. Thereafter, the process returns to step SA9 'and continues to transmit the window closing signal S and the ID signal i until the continuation operation of the lock switch 25 is finished. On the other hand, if it is determined in step SA9 'that the lock switch 25 has not been operated continuously, this flow ends (END). Note that the predetermined time is the same as when the window opening signal P is transmitted, so that an operator's intention that a window opening operation is desired can be accurately determined after the lock switch 25 is pressed and the lock signal is pressed. It is set to a time longer than the time until L is transmitted.

  When the user who has the portable device 2 authenticated on the vehicle-mounted device 4 side gets on the vehicle 1 or gets out of the vehicle, only the door request switch 45 provided on the door knob is operated. Lock control can be performed and convenience can be improved. Further, by operating the lock switch 25 or the unlock switch 26 provided in the portable device 2, the door lock or the door lock release can be remotely operated, and the switches 25 and 26 after the door lock or the door lock is released. By continuing the pressing operation, it is possible to cause the window glass 12a and 12b of the door to be closed or opened.

<Steering lock control>
FIG. 8 shows a flow of steering lock control performed by the in-vehicle device 4 and the portable device 2 following the door lock control described above. The flow of FIG. 8 will be described below.

  First, when the flow of FIG. 8 starts, it is determined whether or not an operation of the ignition knob 49 (for example, a pressing operation forward of the vehicle) is performed on the vehicle-mounted device 4 side (step SB1). If it is determined that the ignition knob 49 has not been operated (in the case of NO), it is not necessary to release the steering lock, so this flow ends (end), while it is determined that the ignition knob 49 has been operated. If YES (YES), the process proceeds to step SB2, and it is determined whether or not an allowable condition for the ignition lock control is satisfied. Specifically, in this step SB2, it is determined whether the ignition is OFF, that is, whether the position of the ignition knob 49 is the accessory OFF or accessory ON position.

  If it is determined in step SB2 that the allowable condition is satisfied (YES), the request signal r is transmitted to the portable device 2 in the following step SB3, and the portable device 2 is transmitted within a predetermined time in step SB4. It is determined whether or not the ID signal i is received from. If it is determined in step SB4 that the ID signal i has not been received (in the case of NO), this flow is ended (end), whereas if it is determined that the ID signal i has been received (YES) In the case of (1), the ID code included in the ID signal i is stored in the memory 44, that is, the ID code is checked to determine whether there is a match (steps SB5 and SB6). . If the code that matches the ID code is stored in the memory 44 (YES in step SB6), the steering unlock control is performed to release the steering lock (step SB7). If this is the case (YES in step SB6), this flow is terminated as it is (end). The predetermined time in step SB4 is set to a time sufficient to receive the ID signal i transmitted from the portable device 2 by the in-vehicle receiving antenna 43 after transmitting the request signal r to the portable device 2. The

  On the other hand, when the steering lock control is started on the portable device 2 side, first, at step SB1 ′, it is determined whether or not the request signal r is received from the in-vehicle device 4, and when the request signal r is received (in the case of YES). In step SB2 ′, the ID signal i is transmitted to the in-vehicle device 4 and this flow is ended (END). On the other hand, if it is determined in step SB1 'that the request signal r has not been received (in the case of NO), this flow is ended as it is (end).

<Engine start control>
FIG. 9 shows a flow of engine start control performed by the in-vehicle device 4 and the portable device 2 following the steering lock control described above. The flow of FIG. 9 will be described below.

  First, when the flow of FIG. 9 starts, it is determined whether or not the operation of the ignition knob 49 (ignition starter) is performed on the in-vehicle device 4 side (step SC1). Specifically, it is determined whether or not the ignition knob 49 has been turned to the position of the ignition START.

  If it is determined in step SC1 that the ignition knob 49 has not been operated (in the case of NO), this flow is terminated as it is (end), while it is determined that the ignition knob 49 has been operated. In the case of (YES), it is determined in the following step SC2 whether or not the starter control prohibition condition is satisfied. Here, when the starter control prohibition condition is met, when the engine is operating, the ignition is off, or the ID code is authenticated in step SC6 described later, but the engine has not started. It means a state where the state continues for 30 minutes.

  If it is determined in step SC2 that the starter control prohibition condition is satisfied (in the case of YES), it is not necessary to perform engine start control, so this flow ends (end), while starter control is prohibited. If it is determined that the condition is not met (in the case of NO), the process proceeds to step SC3, where the request signal r is transmitted to the portable device 2, and the ID signal i is received from the portable device 2 within a predetermined time. It is determined whether or not (step SC4). If it is determined in step SC4 that the ID signal i has been received within the predetermined time (in the case of YES), the ID code is checked to determine whether or not there is a matching ID code in the memory 44. (Steps SC5 and SC6). On the other hand, if it is determined in step SC4 that the ID signal i has not been received (in the case of NO), this flow is ended (END). The predetermined time in step SC4 is set to a time sufficient to receive the ID signal i transmitted from the portable device 2 by the in-vehicle receiving antenna 43 after transmitting the request signal r to the portable device 2. The

  If it is determined in step SC6 that there is an ID code that matches the ID code included in the ID signal i in the memory 44 (in the case of YES), then in step SC7, the smart keyless control unit 4 moves the engine control unit. The engine start permission signal is output to 50 to perform ignition starter control for starting the engine. On the other hand, if it is determined that there is no matching ID code (in the case of NO), this flow is ended as it is ( End).

  On the other hand, when the engine start control is started on the portable device 2 side, first, at step SC1 ′, it is determined whether the request signal r is received from the in-vehicle device 4, and when the request signal r is received (in the case of YES). In step SC2 ′, the ID signal i is transmitted to the in-vehicle device 4 and this flow is ended (END). On the other hand, if it is determined in step SC1 'that the request signal r has not been received (in the case of NO), this flow is ended as it is (end).

  It should be noted that the following conditions are met instead of transmitting the request signal r and collating the ID code of the portable device 2 only when the ignition knob 49 is rotated to the ignition START position in step SC1. Sometimes, the operations of steps SC2 to SC6 may be performed in advance to collate the ID code of the portable device 2. Specifically, (i) the operation of the ignition knob 49 from the accessory OFF to the accessory ON (ii) 3 seconds have passed since the accessory was turned on (iii) 60 seconds have passed since the ignition was turned on When the condition is satisfied, the ignition knob 49 is likely to be operated to the ignition START after that, so the ID code of the portable device 2 is collated in advance. If authentication of the ID code is obtained, when the ignition knob 49 is operated to the position of the ignition START, the ignition starter that starts the engine without performing steps ID to SC6 and collating the ID code when the ignition knob 49 is operated to the ignition START position. Take control.

<Forgotten control>
In the above-described door lock control, misplacement control performed after the door is locked will be described below based on the flow shown in FIG.

  When the flow of FIG. 10 starts, the in-vehicle device 4 first estimates the timing (time zone) at which the window closing signal S may be received from the portable device 2 located outside the vehicle after the door is locked in step SD1. . Specifically, it is considered that the window closing signal S is transmitted from the portable device 2 every predetermined time interval (for example, approximately every 0.5 seconds) after receiving the lock signal L (or after the door is locked). Thus, the timing of receiving the window closing signal S is estimated.

  In step SD2, the reception timing estimated in step SD1 and the transmission timing of the ID signal i from the portable device 3 located in the vehicle interior do not overlap each other (for example, at intervals of 0.5 seconds). A request signal r is transmitted to the portable device 3 at a slightly later timing. That is, after the door is locked, a request signal r is transmitted to the vehicle interior in order to check whether the portable device has been left behind in the vehicle interior. When the transmission timing of the transmitted ID signal i overlaps with the reception timing at which the vehicle-mounted device 4 receives the window closing signal S from the portable device 2 located outside the vehicle, generally, the distance to the vehicle-mounted receiving antenna 43 and obstacles For example, the window closing signal S may have a lower transmission intensity and may not be received by the in-vehicle receiving antenna 43. Therefore, by delaying the transmission timing of the ID signal i from the in-vehicle device 3 located in the vehicle interior with respect to the reception timing of the window closing signal S estimated in the step SD1, the window closing signal S is surely set. The vehicle-mounted receiving antenna 43 can be used for reception.

  For portable devices for which the ID code is not authenticated within a predetermined time (first predetermined time) before the lock signal L is received or the door is locked, the vehicle may be registered even if the ID code is registered in the memory 44. Since it is considered that the ID code is not present in the room or the ID code is not registered in the memory 44, the control as in step SD2 may not be performed. Further, even when the window closing signal S is not transmitted from the portable device 2 within a predetermined time (second predetermined time) after the door is locked, the control as in step SD2 may not be performed. By doing so, when the ID signal i does not interfere with the window closing signal S, the request signal r is not unnecessarily delayed, and the time required for confirmation of misplacement can be shortened.

  Here, the predetermined time before the door is locked means a time during which the portable transceiver is unlikely to be brought into the vehicle compartment or taken out of the vehicle, and the predetermined time after the door is locked. When the door is locked, it means the time required for the window closing signal S to be received by the in-vehicle receiver after the window closing signal S is transmitted from the portable transceiver to the lock signal. .

  Further, in step SD2, the request signal r to the passenger compartment is transmitted with a little delay from the normal transmission timing. However, the present invention is not limited to this, and the request signal r is not detected within the predetermined time. The order of transmitting the request signal r and the detected request signal r to the portable device may be switched and transmitted. This also shortens the time for confirmation of misplacement in the passenger compartment.

  After transmitting the request signal r into the vehicle compartment at the step SD2, it is confirmed at the subsequent step SD3 whether or not the ID signal i has been received from the portable device within a predetermined time. If the reception of the ID signal i is not confirmed, that is, if there is no portable device left in the passenger compartment (in the case of NO), the flow is ended as it is (end). On the other hand, when the reception of the ID signal i is confirmed, that is, when there is a portable device 3 that is left behind in the vehicle interior (in the case of YES), the ID code included in the received ID signal i is collated, It is determined whether or not it matches the ID code stored in the memory 44 (steps SD4 and SD5). If the ID code included in the received ID signal i is authenticated in step SD5 (in the case of YES), the process proceeds to step SD6 until the door is unlocked by the portable device 2 outside the vehicle. The portable device 3 left behind in the room is invalidated, and a warning lamp 51 or buzzer 52 notifies the user that the device has been left behind. The predetermined time in step SD3 is set to a time sufficient to receive the ID signal i transmitted from the portable device 3 by the in-vehicle receiving antenna 43 after transmitting the request signal r to the portable device 3. The

  On the other hand, when the misplacement control is started on the portable device 3 side located in the vehicle interior, first, at step SD1 ', it is determined whether or not the request signal r is received from the in-vehicle device 4. When the request signal r is received (in the case of YES), the process proceeds to step SD2 ', the ID signal i is transmitted to the in-vehicle device 4, and this flow is ended (END). On the other hand, if it is determined in step SD1 'that the request signal r has not been received (in the case of NO), this flow is ended as it is (end).

  Here, step SD1 for estimating the reception timing of the window closing signal S transmitted from the portable device 2 located outside the vehicle corresponds to the timing prediction unit 40b, and steps SD2 to SD5 for performing misplacement determination correspond to the misplacement determination unit 40c, respectively. is doing.

  As described above, in the present embodiment, in the smart keyless system A configured to be able to open and close the window glasses 12a and 12b by the portable device 2 located outside the vehicle and to confirm the misplacement of the portable device 3 in the vehicle interior, The window closing signal S transmitted from the portable device 2 is transmitted to the portable device 3 so that the reception timing at the in-vehicle receiving antenna 43 and the transmission timing of the ID signal i transmitted from the portable device 3 do not overlap. By shifting the transmission timing of the request signal r, the window closing signal S is reliably received by the in-vehicle receiving antenna 43, and the window closing operation is not interrupted due to the influence of the ID signal i, which makes the operator feel uncomfortable. There is no.

  Further, even if a portable device whose ID code is not authenticated within a predetermined time before the door lock, or when a portable device whose ID signal is authenticated exists in the vehicle interior, the window closing signal S within the predetermined time from the door lock. Is not received, there is no possibility of interfering with the window closing signal S without delaying the transmission timing of the ID signal i, so that the request signal r can be quickly requested by not delaying the transmission timing of the request signal r. The signal r can be transmitted, and the time required for confirmation of misplacement can be shortened.

(Embodiment 2)
In the second embodiment, as shown in FIGS. 11 and 12, in the misplacement control, when the window closing signal S is transmitted from the portable device 2 located outside the vehicle, the reception timing at the in-vehicle receiving antenna 43 is set. When it is estimated that the reception timing overlaps with the transmission timing of the ID signal i from the portable device 3 located in the passenger compartment, the transmission strength of the ID signal i is reduced. . Therefore, it differs from the above-described first embodiment only in that the transmission intensity of the ID signal i transmitted from the portable device 3 located in the vehicle interior is reduced in misplacement control, and only the parts different from the first embodiment are different. This will be described in detail below.

  That is, as shown in FIG. 11, when the lock signal L is transmitted from the portable device 2 located outside the vehicle and received by the in-vehicle receiving antenna 43, the smart keyless control unit 40 of the in-vehicle device 4 causes the door lock actuator 47 to The lock control to drive is performed. At this time, the smart keyless control unit 40 requests a request signal r (hereinafter also referred to as misplacement confirmation signals A to F) for confirming whether there is a portable device left misplaced in the vehicle interior. Are transmitted to a plurality of portable devices registered in the memory 44 in advance, while the window closing signal S is intermittently transmitted from the portable device 2. Estimates the reception timing.

  When the smart keyless control unit 40 transmits the misplacement confirmation signals A to F, for example, the reception timing and the ID signal i (hereinafter also referred to as ID signal B) from the portable device 3 for the misplacement confirmation signal B are transmitted. When the transmission timing is estimated to overlap with the transmission timing of (), the transmission strength reduction signal T is added to the misplacement confirmation signal B so as to reduce the transmission strength of the ID signal B to the portable device 3 for transmission. To do.

  In order to confirm the presence of the portable device 3 in the passenger compartment, the ID code is authenticated even before the lock signal L is received, and the ID code is authenticated within a predetermined time after the lock signal L is received. You may be made not to perform the control which reduces the transmission intensity | strength of ID signal i as mentioned above with respect to the portable device which was not obtained. In addition, even when there is a portable device with ID code authentication, after receiving the lock signal L, if the window close signal S is not received within the time when the window close signal is expected to be received, Similarly, the control for reducing the transmission intensity of the ID signal i may not be performed. Here, the predetermined time retroactively from when the lock signal L is received means a time during which the portable transceiver is unlikely to be brought into the vehicle interior or taken out of the vehicle, and the window is closed. The time when the reception of the signal is predicted is a time predicted based on the lock signal L transmitted from the portable device 2. Specifically, the window closing signal is transmitted from the portable device 2 to the lock signal L. It means the time required for the window closing signal S to be received by the in-vehicle receiving antenna 43 after S is transmitted.

  In the above misplacement confirmation signal, signals corresponding to a plurality of portable devices are transmitted, and in order to cover the entire vehicle interior, a plurality of transmission antennas 41a, 41b, 42a, 42b having transmission areas in the vehicle interior are sequentially provided. Since it is transmitted, if the transmission timing of the request signal r is delayed unnecessarily, the time required for confirmation of misplacement becomes longer. Therefore, as described above, when there is no possibility that the ID signal i and the window closing signal S interfere with each other, it is possible to shorten the misplacement confirmation time by not reducing the transmission intensity of the request signal r. it can.

  Here, as described above, the smart keyless control unit 40 that authenticates the ID code and confirms the presence of the portable device 3 before receiving the lock signal L receives the lock signal L to the portable transceiver confirmation unit. The smart keyless control unit 40 that does not reduce the transmission intensity of the request signal r for the portable device for which the ID code authentication is not obtained within a predetermined time retroactively from the time of the The smart keyless control unit 40 is configured to prevent the transmission intensity of the request signal r from being lowered when the window closing signal S is not received within a time when reception of the window closing signal is predicted after receiving L. Corresponds to each prohibited section.

  Specifically, the operations of the in-vehicle device 4 and the portable device 3 in the present embodiment will be described below based on the flow of FIG.

  On the in-vehicle device 4 side, when the flow on the left side of FIG. 12 starts, first, the reception timing of the window closing signal S transmitted from the portable device 2 located outside the vehicle is estimated (step SE1). Thereafter, the transmission intensity is applied to the request signal r (corresponding to the misplacement confirmation signal B in FIG. 11) transmitted at a timing at which the estimated reception timing and the transmission timing of the ID signal i from the portable device 3 located in the vehicle cabin are likely to overlap. The lowering signal T is added and transmitted (step SE2). This transmission strength lowering signal T is for lowering the transmission strength of the ID signal i with respect to the portable device 3 existing in the passenger compartment.

  Then, in the next step SE3, it is determined whether or not the ID signal i from the portable device has been received within a predetermined time after the transmission of the request signal r. On the other hand, when the ID signal i is received, the ID code included in the ID signal i is collated (step SE4). The predetermined time in step SE3 is set to a time sufficient to receive the ID signal i transmitted from the portable device 3 by the in-vehicle receiving antenna 43 after transmitting the request signal r to the portable device 3. The

  Subsequently, in step SE5, it is determined whether or not the ID code has been authenticated. If the authentication has been obtained (in the case of YES), the door lock is then released by the portable device 2 outside the vehicle in step SE6. Until this is done, the portable device 3 in the passenger compartment is invalidated and a warning lamp 51 and a buzzer 52 notify the user that the portable device 3 has been left behind. Thereafter, this flow ends (END). On the other hand, if the ID code is not authenticated in the step SE5 (in the case of NO), even if a portable device exists in the passenger compartment, various operations cannot be performed on the portable device, which is invalid. This flow is finished as it is (end).

  On the other hand, when the flow on the right side of FIG. 12 is started on the portable device 3 side located in the vehicle interior, it is determined whether or not the request signal r is received from the in-vehicle device 4 (step SE1 '). If the request signal r has not been received (in the case of NO), this flow is terminated (end). On the other hand, if the request signal r has been received (in the case of YES), the request signal is as described above. Since the transmission strength reduction signal T is added to r, the transmission strength of the ID signal i is set according to the transmission strength reduction signal T (step SE2 ′), and the ID signal i is transmitted (step SE3 ′). . Thereafter, this flow is ended (END).

  Here, step SE1 for estimating the reception timing of the window closing signal S transmitted from the portable device 2 located outside the vehicle corresponds to the timing prediction unit 40b, and steps SE2 to SE5 for performing misplacement determination correspond to the misplacement determination unit 40c, respectively. is doing.

  As described above, in the present embodiment, when the window closing signal S is transmitted from the portable device 2 located outside the vehicle and the in-vehicle device 4 transmits the misplacement confirmation signals A to F in the vehicle interior, Even if the reception timing of the window closing signal S and the transmission timing of the ID signal i from the portable device 3 with respect to the misplacement confirmation signal B overlap, by reducing the transmission intensity of the ID signal i, the ID signal i The window closing signal S can be prevented from being interrupted, and the window closing operation can be prevented from being interrupted due to the window closing signal S not being received by the vehicle-mounted device 4.

  In addition, even if the portable device whose ID code is not authenticated within a predetermined time before the door lock or when the portable device whose ID code is authenticated exists in the vehicle interior, the window closing signal S within the predetermined time from the door lock. Is not received, there is no possibility of interfering with the window closing signal S without delaying the transmission timing of the ID signal i, so that the request signal r can be quickly requested by not delaying the transmission timing of the request signal r. The signal r can be transmitted, and the time required for confirmation of misplacement can be shortened.

  As described above, the ID signal i transmitted from the portable device 3 may not be received on the in-vehicle device 4 side by reducing the transmission intensity of the ID signal i from the portable device 3 located in the vehicle interior. However, as shown in FIG. 11, the misplacement confirmation signals A to F are transmitted twice or more, so that the detection accuracy of misplacement of the portable device 3 is ensured.

(Embodiment 3)
In the third embodiment, as shown in FIGS. 13 and 14, when the window closing signal S is transmitted from the portable device 2 located outside the vehicle in the misplacement control, the reception timing at the in-vehicle receiving antenna 43 is set. When it is estimated that the reception timing and the transmission timing of the ID signal i from the portable device 3 located in the passenger compartment overlap, the window closing signal S is received by the in-vehicle reception antenna 43 at that time. Even if not, the window closing operation is continued. Therefore, since the control for the window closing operation is different in the mishandling control as compared with the first and second embodiments, only the portions different from the first and second embodiments will be described in detail below.

  That is, as shown in FIG. 13, when the lock signal L is transmitted from the portable device 2 located outside the vehicle and received by the in-vehicle receiving antenna 43, the smart keyless control unit 40 of the in-vehicle device 4 drives the door lock actuator 47. Perform lock control. At that time, the smart keyless control unit 40 requests a request signal r (hereinafter also referred to as misplacement confirmation signals A to E) for confirming whether or not there is a portable device left in the passenger compartment. When the window closing signal S is intermittently transmitted from the portable device 2, the reception timing is estimated.

  The smart keyless control unit 40 estimates that the reception timing and the transmission timing of the ID signal i (hereinafter also referred to as ID signal B) from the portable device 3 with respect to the misplacement confirmation signals A to E overlap. The window closing operation is continued even if the window closing signal S is not received by the in-vehicle receiving antenna 43 at that time. When the window closing operation is continued while the window closing signal S is not received, the transmission timing of the next window closing signal S is normally set to the portable device 2 that transmits the window closing signal S (for example, 0). The instruction may be issued so as to be earlier than the timing (predetermined timing) of .5 seconds).

  Specifically, the operation of the smart keyless device according to the present embodiment will be described below based on the flow of FIG.

  When the flow of FIG. 14 is started, on the in-vehicle device 4 side, first, the reception timing of the window closing signal S transmitted from the portable device 2 located outside the vehicle is estimated (step SF1). Thereafter, when the estimated reception timing and the transmission timing of the ID signal i from the portable device 3 located in the passenger compartment are likely to overlap, when the ID signal i is received and the window closing signal S is not received However, the window closing operation is set to continue (step SF2), and the request signal r is transmitted toward the vehicle interior (step SF3). In step SF2, the next pulse signal of the window closing signal S is transmitted to the portable device 2 located outside the vehicle earlier than a normal interval that is a predetermined interval (for example, an interval of 0.5 seconds). An instruction signal may be transmitted. At this time, the step SF2 corresponds to the pulse control unit 40d.

  In the subsequent step SF4, it is determined whether or not the ID signal i from the portable device has been received within a predetermined time after the transmission of the request signal r. If the ID signal i has not been received, this flow is terminated. (End) On the other hand, when the ID signal i is received, the ID code included in the ID signal i is collated (step SF5). When the ID signal i is received, the window closing operation is continued even if the window closing signal S is not received from the portable device 2 outside the vehicle as described above. The predetermined time in step SF4 is set to a time sufficient to receive the ID signal i transmitted from the portable device 3 by the in-vehicle receiving antenna 43 after transmitting the request signal r to the portable device 3. The

  In step SF6, it is determined whether authentication of the ID code is obtained. If authentication is obtained (in the case of YES), the door lock is then released by the portable device 2 outside the vehicle in step SF7. Until this is done, the portable device 3 in the passenger compartment is invalidated and a warning is given to the user. Thereafter, this flow ends (END). On the other hand, if the ID code authentication is not obtained in the step SF6 (in the case of NO), even if a portable device exists in the passenger compartment, various operations cannot be performed on the portable device, which is invalid. Since there is no need to perform the digitizing process, this flow ends as it is (end).

  On the other hand, on the side of the portable device 3 located in the vehicle interior, when the flow of FIG. 14 starts, it is determined whether the request signal r is received from the in-vehicle device 4 (step SF1 '). If the request signal r has not been received (in the case of NO), this flow is terminated (end), whereas if the request signal r has been received (in the case of YES), the ID signal i is transmitted. (Step SF2 ′), this flow is finished (End).

  Here, step SF1 for estimating the reception timing of the window closing signal S transmitted from the portable device 2 located outside the vehicle corresponds to the timing prediction unit 40b, and steps SF2 to SF6 for performing misplacement determination correspond to the misplacement determination unit 40c, respectively. is doing.

  As described above, in the present embodiment, the window close signal S is transmitted from the portable device 2 located outside the vehicle, and the in-vehicle device 4 transmits the misplacement confirmation signals A to E (request signals r) in the vehicle interior. The reception timing of the window closing signal S at the in-vehicle reception antenna 43 overlaps with the transmission timing of the ID signal B from the portable device 3 for the misplacement confirmation signals A to E, and the ID signal B is received. Even if the window closing signal S is not received, the window closing operation is continued, so that the window closing operation can be prevented from being interrupted due to the influence of the ID signal i, and the operator feels uncomfortable. Can be prevented.

  Further, since the window closing signal S cannot be received by the ID signal B, when the window closing operation is continued, the next window closing signal S transmitted from the portable device 2 is transmitted earlier than the normal timing. The operator's intention can be quickly confirmed, and an operation different from the operator's intention can be prevented.

That is, in each of the above embodiments, when the portable device 3 is left in the passenger compartment, the invalidation and warning of the portable device 3 is performed, but this is not the case and the portable device 3 is left without warning. You may just disable the mobile device.

  In the first embodiment, the transmission timing of the ID signal i is delayed from the transmission timing of the window closing signal S. However, the present invention is not limited to this, and the transmission timing of the ID signal is more than the transmission timing of the window closing signal. You may make it advance.
