  The back door 40 is attached to the rear part of the vehicle body 25 so as to swing around the first opening / closing axis L1 extending in the horizontal direction at the upper part of the vehicle body 25. The back door 40 swings up and down.

  A back door latch device 41 for locking the back door 40 is attached to the lower end of the back door 40. The back door latch device 41 has two states, a latch state that engages with the back door striker 31 that is attached to the center of the lower edge 30d of the rear opening 30 and an unlatched state that does not engage with the back door striker 31. Switching is possible. When the back door latch device 41 is in a latched state where the back door striker 31 is engaged with the back door striker 31, the back door 40 is closed. The back door latch device 41 is configured by an electromagnetic mechanism that electromagnetically switches between a latched state and an unlatched state.

  The opening operation of the back door 40 is performed by a back door opening operation unit 43 provided in the back door 40. The back door opening operation unit 43 is, for example, a back door handle 43 provided at the right end of the back door side recess 42. The back door handle 43 is covered with a back door side garnish 49, and the lower side is opened so that it can be grasped from below.

  The back door handle 43 is provided with a back door opening switch 46 for opening the back door 40. The openable state of the back door 40 is a state in which the back door latch device 41 is switched from the latched state to the unlatched state. The back door opening switch 46 includes, for example, a touch sensor or a push button switch.

  The sub door opening 50 has a substantially rectangular shape, and has an upper edge 50a formed along the upper edge 30a of the rear opening 30, a right edge 50b lowered from the right end of the upper edge 50a, and an upper edge. The left edge 50c is lowered from the left end of 50a and extends along the side edge 30c of the rear opening 30, and a lower edge 50d connecting the lower ends of these side edges 50b and 50c.

  The pillar 44 is provided with two hinges 45 and 45 that support the sub door 60 so as to be rotatable in the horizontal direction. The sub door 60 is supported by the pillar 44 via two hinges 45, 45, and has a so-called side-open configuration. An axis passing through the centers of the two hinges 45 and extending in the vertical direction is called a second opening / closing axis L2, and the sub door 60 swings around the second opening / closing axis L2. The sub door 60 swings in the front-rear direction and the horizontal direction of the vehicle body 25. At this time, the sub door 60 opens from the other end portion on the opposite side to the driver seat side (the left edge 30c side of the rear opening 30).

  A sub door latch device 61 for locking the sub door 60 is attached to the end of the sub door 60 on the passenger seat side. The sub door latch device 61 can switch between two states: a latch state in which the sub door striker 51 attached to the left edge 50c of the sub door opening 50 is engaged, and an unlatched state in which the sub door striker 51 is not engaged. The sub door 60 is closed when the sub door latch device 61 engages with the sub door striker 51. The subdoor latch device 61 is configured by an electromagnetic mechanism that electromagnetically switches between a latched state and an unlatched state.

  The opening operation of the sub door 60 is performed by a sub door opening operation unit 63 provided in the sub door 60. For example, the sub-door opening operation unit 63 is a sub-door outer handle 63 attached from the end of the sub-door 60 on the passenger seat side toward the vehicle width center C2.

  The sub door outer handle 63 is provided with a sub door opening switch 66 for opening the sub door 60. The openable state of the subdoor 60 is a state in which the subdoor latch device 61 is switched from the latched state to the unlatched state. As an example, the sub-door opening switch 66 includes a touch sensor or a push button switch.

  A sub door inner handle (not shown) for opening the sub door 60 is further arranged on the inner side surface of the sub door 60. That is, the sub door 60 can perform the opening operation of the sub door 60 from either the sub door outer handle 63 or the sub door inner handle. The sub door inner handle is provided with an inner opening switch. By operating the inner opening switch, the sub door latch device 61 is switched from the latched state to the unlatched state. As an example, the inner opening switch is configured by, for example, a touch sensor or a push button switch.

  The sub door outer handle 63 is located above the back door handle 43. In other words, the back door handle 43 and the sub-door outer handle 63 are attached to positions that are separated from each other in the vehicle width direction and different in the height direction. Thereby, confusion between the back door handle 43 and the sub-door outer handle 63 can be prevented, and operability can be improved.

  In addition, since the back door handle 43 is positioned below the sub door outer handle 63, the back door 40 can be operated with a smaller operating force. Further, since the sub door outer handle 63 is positioned above the back door handle 43, the sub door 60 can be easily operated in a standing state.

  Among the sub doors 60, between the sub door outer handle 63 and the back door handle 43 in the vehicle width direction, a lock switch 23 is disposed that locks at least one door lock device included in the vehicle 10. One lock switch 23 is arranged. For example, the lock switch 23 includes a touch sensor, a push button switch, or the like.

  The position of the lock switch 23 is not limited as long as it is between the back door handle 43 and the sub door outer handle 63 in the vehicle width direction, but when the occupant closes the back door 40 and the sub door 60, the lock switch 23 It is preferable to arrange | position in the position where 23 is easy to operate. The lock switch 23 is provided at a position other than the back door handle 43 and the sub door outer handle 63 so that the passenger can distinguish from the back door release switch 46 and the sub door release switch 66.

  A smart entry system, which will be described later, is placed on the vehicle outer side panel 40a of the back door 40 or the vehicle outer side panel 60a of the sub door 60 at a position between the back door opening operation portion 43 and the sub door opening operation portion 63 in the vehicle width direction. An antenna 81 is attached. As an example, the antenna 81 is a substantially intermediate position between the back door opening operation portion 43 and the sub door opening operation portion 63 in the vehicle width direction, and at a height below the license recess 72 in the height direction. The sub door 60 is attached to the vehicle outer side panel 60a. In the example shown in FIG. 2, the antenna 81 is arranged at a position offset to the left side from the vehicle width center C2.

  If the arrangement position of the antenna 81 is limited to the center C2 of the vehicle width, for example, depending on the width of the sub door 60, the relationship with the right edge 50b of the sub door opening 50 or the hinge 45, or the mounting shape of the sub door garnish 69. There are many restrictions on the arrangement of the antenna 81, such as the difficulty of arranging the antenna 81. Therefore, the arrangement position of the antenna 81 is limited to the vehicle width center C2 so that the antenna 81 can be arranged at an appropriate position in relation to the positions of the back door opening operation section 43 and the sub door opening operation section 63. Preferably not.

  As described above, the antenna 81 is disposed on the outer panel 40 a of the movable back door 40 or the outer panel 60 a of the sub door 60. As a result, compared to the case where the antenna 81 is not movable, for example, disposed on a bumper face or the like, the cost and weight associated with wiring using hard wires to be described later can be reduced. Further, in order to realize the enlargement of the rear opening 30, the vertical length of the bumper face is smaller than the vertical length of the antenna 81, which is also effective when the antenna 81 cannot be disposed on the bumper face.

  For example, the vehicle exterior side of the vehicle exterior panel 40a of the back door 40 below the license recess 72 is covered with a back door side resin member 39, for example. For example, the vehicle exterior side of the vehicle exterior panel 60 a of the sub door 60 is covered with a sub door side resin member 59. The back door side resin member 39 and the sub door side resin member 59 continuously extend in the vehicle width direction. That is, the antenna 81 attached to the vehicle outer side panel 60 a of the sub door 60 is covered with the sub door side resin member 59 on the vehicle outer side.

  FIG. 4 shows an antenna 81 for a smart entry system that is attached to the vehicle outer side panel 60a of the sub door 60 and whose vehicle outer side is covered by the sub door side resin member 59. The vehicle exterior panel 60a of the sub door 60 near the position where the antenna 81 is attached is formed in a concave shape as viewed from the vehicle exterior. The stay 73 is formed so that the center portion protrudes to the vehicle outer side, and round screw holes 75 and 75 are formed at both ends of the stay 73. The round screw 74 penetrates the round screw hole 75 and the through hole 76 formed in the vehicle outer side panel 60a from the outside of the vehicle and is fixed with a nut 77, so that the stay is formed in the concave portion of the vehicle outer side panel 60a. 73 is attached. The antenna 81 is attached to the vehicle outer side panel 60a of the sub door 60 by being fixed to the flat portion of the central portion of the stay 73 by screws or bonding. The sub door-side resin member 59 covers the outside of the vehicle 81 of the antenna 81 and the vehicle outer side panel 60a of the sub door 60 to which the antenna 81 is attached.

  The outside of the vehicle 81 and the outside panel 60a of the sub door 60 to which the antenna 81 is attached is covered with the sub door side resin member 59, so that the communication performance of the antenna 81 can be ensured and the design can be improved. .

1-2. Configuration and Operation of Smart Entry System As shown in FIG. 5, the smart entry system is applied to the vehicle 10. The smart entry system includes an antenna 81, a back door opening switch 46, and a sub door opening switch 66 for communicating with a portable device 86 carried by a passenger. The smart entry system may further include a lock switch 23, a side door door lock device 22, a smart ECU 83, a double door ECU 84, a door lock control ECU 85, and the like.

  The smart ECU 83, the double door ECU 84, and the door lock control ECU 85 are connected to each other by an in-vehicle LAN such as a CAN 91 (Control Area Network). One or more of the smart ECU 83, the double door ECU 84, and the door lock control ECU 85 or at least one including the smart ECU 83 constitute the control unit 82 of the smart entry system.

  The smart ECU 83 is connected to the back door opening switch 46, the sub door opening switch 66, the lock switch 23, and the antenna 81 by, for example, a hard wire 92a. The smart ECU 83 may be further connected to at least one side door opening switch (not shown) provided in each of the side doors 21, 21, 21, and 21 by a hard wire 92a. The double door ECU 84 is connected to the back door opening switch 46, the sub door opening switch 66, the back door latch device 41, and the sub door latch device 61 by, for example, a hard wire 92b. The door lock control ECU 85 is connected to, for example, at least one (preferably all) of the side door door lock devices 22 provided in each of the side doors 21, 21, 21, and 21 by a hard wire 92c. .

  Input / output of signals between the ECUs, devices, and the like connected by the hard wires 92a, 92b, and 92c are continuous in time. On the other hand, the input / output of signals between ECUs connected by CAN 91 is discrete in time. Therefore, signals between the ECUs and devices connected by the hard wires 92a, 92b, and 92c are input / output faster than signals between the ECUs connected by the CAN 91. As a result, a series of operations by the smart entry system described below can be accelerated compared to a case where all ECUs, devices, and the like are connected by CAN 91.

  The back door opening switch 46 outputs, for example, a back door operation acceptance signal to the double door ECU 84 via the hard wire 92b when an operation by the occupant is performed on the back door opening switch 46. Here, the operation by the occupant with respect to the back door opening switch 46 is, for example, that the occupant touches the touch sensor constituting the back door opening switch 46 or depresses the push button switch.

  The sub door opening switch 66 outputs, for example, a sub door operation acceptance signal to the double door ECU 84 via the hard wire 92b when an operation by the occupant is performed on the sub door opening switch 66. Here, the operation by the occupant with respect to the sub door opening switch 66 is, for example, that the touch sensor constituting the sub door opening switch 66 is touched or the push button switch is pressed by the occupant.

  The double door ECU 84 outputs a back door operation detection signal or a sub door operation detection signal to the smart ECU 83 via the CAN 91 when a back door operation reception signal or a sub door operation reception signal is input.

  The double door ECU 84 detects the states of the back door latch device 41 and the sub door latch device 61 via the hard wire 92b. The double door ECU 84 outputs a latch state detection signal to the smart ECU 83 via the CAN 91 when both the back door latch device 41 and the sub door latch device 61 are in the latch state. Further, the double door ECU 84 outputs an unlatched state detection signal to the smart ECU 83 via the CAN 91 when at least one of the back door latch device 41 and the sub door latch device 61 is in an unlatched state.

  The smart ECU 83 transmits a predetermined signal from the antenna 81 when the latch state detection signal is input and the back door operation detection signal or the subdoor operation detection signal is input. Here, the predetermined signal transmitted from the antenna 81 is, for example, a request signal for the portable device 86 carried by the passenger. The smart ECU 83 does not transmit a predetermined signal from the antenna 81 even when the back door operation detection signal or the sub door operation detection signal is input when the unlatch state detection signal is input.

  When at least one of the back door latch device 41 and the sub door latch device 61 is in an unlatched state, it is possible to further change at least one of the back door latch device 41 and the sub door latch device 61 into an unlatched state. Impossible. Accordingly, when the smart ECU 83 receives the unlatched state detection signal, the smart ECU 83 does not transmit the predetermined signal from the antenna 81 even if the back door operation detection signal or the subdoor operation detection signal is input. Such waste of power consumption can be prevented.

  When the portable device 86 receives the request signal transmitted from the antenna 81, the portable device 86 transmits a response signal including the ID information of the smart ECU 83 stored in the portable device 86.

  When the smart ECU 83 receives a response signal transmitted from the portable device 86 via the antenna 81, the smart ECU 83 determines whether or not the ID information included in the response signal matches its own ID information. When the smart ECU 83 inputs the back door operation detection signal or the sub door operation detection signal and determines that the ID information included in the response signal matches the ID information of itself, the smart ECU 83 doubles the unlatch request signal via the CAN 91. It outputs to door ECU84.

  When the unlatch request signal is input, the double door ECU 84 switches the state of the latch device of the door corresponding to the opening switch operated by the occupant from the latched state to the unlatched state. That is, when the back door opening switch 46 is operated by the occupant, the back door latch device 41 is switched from the latched state to the unlatched state, while when the sub door opening switch 66 is operated, the sub door latch device 61 is switched. Is switched from the latched state to the unlatched state.

  In the double door ECU 84, when the unlock request signal is input, or at least one state of the door lock device 22 for the side door provided in each of the side doors 21, 21, 21, 21 is an unlocked state. Then, the state of the latch device of the door corresponding to the opening switch operated by the occupant is switched from the latched state to the unlatched state. Therefore, when at least one state of the side door door locking device 22 provided in each of the side doors 21, 21, 21, 21 is in the locked state, the occupant does not carry the portable device 86 for the back door. Even if the opening switch 46 or the sub door opening switch 66 is operated, neither the back door latch device 41 nor the sub door latch device 61 switches from the latched state to the unlatched state. Similarly, when the ID information included in the response signal transmitted from the portable device 86 does not match the ID information of the smart ECU 83, both the back door latch device 41 and the sub door latch device 61 are changed from the latched state to the unlatched state. There is no switching.

  Note that the inner door opening switch of the sub door inner handle (not shown) is connected to the sub door latch device 61 by, for example, a hard wire (not shown). When the inner opening switch is operated by the occupant, the state of the sub door latch device 61 is switched from the latched state to the unlatched state without being controlled by the control unit 82 of the smart entry system. Here, the operation by the occupant with respect to the inner opening switch is, for example, that the occupant touches the touch sensor constituting the inner opening switch or presses the push button switch.

  For example, a situation in which the inner opening switch is operated by the occupant may occur when the engine 13 of the vehicle 10 is being driven in order for the occupant to go out of the vehicle after the vehicle 10 stops. Whether the portable device 86 exists in the vehicle interior when the sub door latch device 61 is switched to the latched state again after the sub door latch device 61 is switched to the unlatched state due to the operation of the inner release switch by the passenger. A determination is made whether or not. If it is determined by this determination that the portable device 86 is not present in the passenger compartment, for example, a warning is given. This determination is also called NOKEY detection.

  The determination as to whether or not the portable device 86 exists in the passenger compartment is performed by, for example, the method described below. For example, the smart ECU 83 transmits a request signal using a vehicle interior as a transmission range from an antenna attached to the vehicle interior (not shown). The smart ECU 83 determines that the portable device 86 does not exist in the vehicle interior when the response signal including ID information that matches the ID information of the smart ECU 83 is not received from the portable device 86 until the predetermined time elapses. .

  By performing the NOKEY detection, for example, an occupant who does not drive the inner vehicle 10 of two or more occupants while carrying out the engine 13 has carried the portable device 86 out of the vehicle. Occurrence of a situation where the machine 86 does not exist is prevented.

  In addition, when the smart ECU 83 inputs the back door operation detection signal or the sub door operation detection signal and determines that the ID information included in the response signal matches its own ID information, the smart ECU 83 is further unlocked via the CAN. A request signal is output to the door lock control ECU 85. When the unlock request signal is input, the door lock control ECU 85 locks at least one (preferably all) state of the door lock device 22 for the side door provided in each of the side doors 21, 21, 21, 21. Switch from state to unlocked state.

  A back door opening switch 46 is provided on the back door handle 43 which is the back door opening operation unit 43. A sub door opening switch 66 is provided in the sub door outer handle 63 which is the sub door opening operation section 63. Therefore, the occupant can perform the opening operation of the door without moving the hand after the desired door of the back door 40 or the sub door 60 can be opened. Improved operability. Specifically, since the back door latch device 41 and the sub door latch device 61 are configured by an electromagnetic mechanism, the occupant operates either the back door release switch 46 or the sub door release switch 66. Thus, the locking of the desired door of the back door 40 or the sub door 60 by the electromagnetic latch mechanism is released. As a result, it is possible to reduce the complexity of the operation of releasing the mechanical latch of the door after waiting for the unlocking operation by the door lock mechanism, thereby further improving the series of operability when performing the door opening operation. .

  Further, since the back door opening switch 46 and the sub door opening switch 66 also have an unlocking function, it is not necessary to newly provide an unlocking switch, and the cost can be reduced.

  Similarly to the double door ECU 84, the smart ECU 83 may input a back door operation reception signal or a sub door operation reception signal via the hard wire 92a. The smart ECU 83 can also input the back door operation acceptance signal or the sub door operation acceptance signal directly from the back door opening switch 46 or the sub door opening switch 66 to detect the operation of the opening switch by the occupant at an early stage. As a result, a series of operations of switching from the latched state of the latch device to the unlocked state and switching from the locked state to the unlocked state of the side door lock device 22 can be accelerated from the operation of the release switch by the occupant. .

  The lock switch 23 outputs, for example, a lock operation acceptance signal to the smart ECU 83 via the hard wire 92a when the occupant operates the lock switch 23. Here, the operation by the occupant on the lock switch 23 is, for example, that the occupant touches the touch sensor constituting the lock switch 23 or presses the push button switch.

  When the smart ECU 83 inputs a latch state detection signal and also receives a lock operation acceptance signal, the smart ECU 83 transmits a request signal from the antenna 81 as a predetermined signal to the portable device 86 carried by the occupant, for example. The request signal here may be the same as or different from the request signal transmitted from the antenna 81 when the smart ECU 83 inputs the back door operation detection signal or the subdoor operation detection signal. When the smart ECU 83 receives the unlatch state detection signal, the smart ECU 83 does not transmit a predetermined signal from the antenna 81 even if the lock operation acceptance signal is input.

  When at least one of the back door latch device 41 and the sub door latch device 61 is in an unlatched state, the side door door lock device 22 cannot be locked. Therefore, when the smart ECU 83 inputs the unlatch state detection signal, even if the lock operation acceptance signal is input, the smart ECU 83 does not transmit the predetermined signal from the antenna 81, thereby wasting power consumption related to transmission of the predetermined signal. Can be prevented.

  When the portable device 86 receives the request signal transmitted from the antenna 81, the portable device 86 transmits a response signal including the ID information of the smart ECU 83 stored in the portable device 86.

  When the smart ECU 83 receives a response signal transmitted from the portable device 86 via the antenna 81, the smart ECU 83 determines whether or not the ID information included in the response signal matches its own ID information. The smart ECU 83 outputs a lock request signal to the door lock control ECU 85 via the CAN 91 when it is determined that the ID information included in the response signal matches its own ID information after inputting the lock operation acceptance signal.

  When the door lock control ECU 85 receives the lock request signal, the door lock control ECU 85 unlocks at least one (preferably all) state of the side door door lock device 22 provided in each of the side doors 21, 21, 21, 21. Switch from state to locked state.

  The relationship between the arrangement of the antenna 81 and the transmission range of a predetermined signal transmitted from the antenna 81 will be described with reference to FIG. FIG. 6 shows three regions, region A, region B, and region C. Region A is a region indicating a transmission range of a predetermined signal transmitted from the antenna 81. The region B includes the back door opening operation unit 43 and is a region where an occupant is located when operating the back door opening switch 46. The region C is a region including the sub-door opening operation unit 63 and is a region where an occupant is located when the sub-door opening switch 66 is operated.

  When the occupant performs the opening operation of the back door 40, the portable device 86 is positioned in the region B because the portable device 86 is carried and the back door opening switch 46 is operated. Similarly, when the occupant performs the opening operation of the sub door 60, the portable device 86 is located in the region C because the portable device 86 is carried and the sub door opening switch 66 is operated. That is, it is necessary to set the area A that is the transmission range of the predetermined signal transmitted from the antenna 81 so as to include the area B and the area C.

  The transmission range of the predetermined signal transmitted from the area A, that is, the antenna 81 is determined by the range according to the output from which the predetermined signal is transmitted. Therefore, from the viewpoint of looking down at the rear part of the vehicle 10 as shown in FIG. 6, the inner side of a substantially semicircle centered on the antenna 81 and having a radius corresponding to the output distance to which a predetermined signal is transmitted. Is region A.

  As described above, one antenna 81 is disposed at a position between the back door opening operation portion 43 and the sub door opening operation portion 63 in the vehicle width direction. The transmission range of the predetermined signal transmitted from the antenna 81 is set so as to include the back door opening operation unit 43 and the sub door opening operation unit 63. Then, it is not necessary to provide one antenna for each of the back door 40 and the sub door 60. As a result, the cost for applying the smart entry system, the weight, and the space required for the arrangement of the antenna 81 at the rear of the vehicle body can be reduced.

  As described above, for example, the antenna 81 is attached to a substantially intermediate position between the back door opening operation portion 43 and the sub door opening operation portion 63 in the vehicle width direction. Therefore, when the area A is set so as to include the area B, the area C is also included in the area A. As described above, the antenna 81 is attached at a substantially intermediate position between the back door opening operation portion 43 and the sub door opening operation portion 63 in the vehicle width direction, thereby minimizing the output for transmitting a predetermined signal. Can be suppressed. As a result, it is possible to contribute to prevention of waste of power consumption related to transmission of a predetermined signal and satisfaction of predetermined legal requirements. Further, when the occupant operates the back door opening operation unit 43, the portable device 86 carried by the occupant can receive a predetermined signal transmitted from the antenna 81, and the occupant operates the sub door opening operation unit 63. In this case, the portable device 86 carried by the occupant can be kept uniform with a range in which the predetermined signal transmitted from the antenna 81 can be received. Accordingly, transmission of a predetermined signal transmitted from the antenna 81 to the occupant is performed regardless of whether the back door opening operation unit 43 or the sub door opening operation unit 63 is operated while using only one antenna 81. By not feeling the difference in the range, it leads to a reduction in the sense of incongruity.

  Further, as described above, one lock switch 23 is disposed at a position between the back door opening operation portion 43 and the sub door opening operation portion 63 in the vehicle width direction. Since the back door opening operation unit 43 and the sub door opening operation unit 63 are included in the region A that is a transmission range of a predetermined signal transmitted from the antenna 81, the lock switch 23 is also included in the region A. As a result, since it is not necessary to provide a lock switch for each of the back door 40 and the sub door 60, further cost reduction can be achieved.

  The operation of the vehicle 10 to which the smart entry system is applied will be described with reference to the flowcharts shown in FIGS. 7A, 7B, and 7C. In the description of the flowchart shown in FIG. 7, the detailed description of the same parts as those described above is omitted.

  An operation flow when the back door opening switch 46 is operated by the occupant will be described with reference to FIG. In step S01, the control unit 82 of the smart entry system determines whether or not the back door opening switch 46 has been operated by the passenger. Specifically, the smart ECU 83 determines whether or not a back door operation detection signal is input from the double door ECU 84. When the controller 82 determines that the back door opening switch 46 has been operated, the flow proceeds to step S02. On the other hand, when the control unit 82 does not determine that the back door opening switch 46 has been operated, the operation flow ends. The smart ECU 83 may determine whether or not the back door operation acceptance signal is directly input from the back door opening switch 46 instead of or in combination with the input of the back door operation detection signal.

  In step S02, the control unit 82 of the smart entry system determines whether or not the back door 40 and the sub door 60 are closed. Specifically, the smart ECU 83 determines whether or not a latch state detection signal has been input. When the control unit 82 determines that the back door 40 and the sub door 60 are in the closed state, the flow proceeds to step S03. On the other hand, when the control unit 82 determines that at least one of the back door 40 and the sub door 60 is in the open state, the operation flow ends.

  In step S03, the control unit 82 of the smart entry system transmits a predetermined signal from the antenna 81. Specifically, the smart ECU 83 transmits a request signal from the antenna 81. When the smart ECU 83 receives the response signal transmitted from the portable device 86 that has received the request signal via the antenna 81, the flow proceeds to step S04. Here, when the response signal is not received before the predetermined time elapses after the smart ECU 83 transmits the request signal, the operation flow may be terminated.

  In step S04, the control unit 82 of the smart entry system determines whether or not the ID information included in the response signal received via the antenna 81 matches the own ID information. Specifically, the smart ECU 83 determines whether or not the ID information included in the response signal matches its own ID information. When the control unit 82 determines that the ID information included in the response signal matches the own ID information, the flow proceeds to step S05. On the other hand, when the control unit 82 does not determine that the ID information included in the response signal matches the own ID information, the operation flow ends.

  In step S05, the controller 82 of the smart entry system switches the state of the back door latch device 41 from the latched state to the unlatched state. Specifically, the smart ECU 83 outputs an unlatch request signal to the double door ECU 84, and the double door ECU 84 switches the back door latch device 41 from the latched state to the unlatched state.

  In step S06, the controller 82 of the smart entry system switches the state of the door lock device 22 for the side door from the locked state to the unlocked state. Specifically, the smart ECU 83 outputs an unlock request signal to the door lock control ECU 85, and the door lock control ECU 85 of the side door door lock device 22 provided in each of the side doors 21, 21, 21, 21. At least one (preferably all) state is switched from the locked state to the unlocked state.

  When step S06 ends, the operation flow ends. Note that the order of step S05 and step S06 may be interchanged or may be performed simultaneously.

  With reference to FIG. 7B, an operation flow when the passenger opens the sub door opening switch 66 will be described. Of the steps of the operation flow shown in FIG. 7B, the same operation flow as the operation flow shown in FIG. 7A described above is described only for the corresponding relationship, and detailed description thereof is omitted.

  In step S11, the controller 82 of the smart entry system determines whether or not the sub door opening switch 66 has been operated by the passenger. Specifically, the smart ECU 83 determines whether or not the sub door operation detection signal is input from the double door ECU 84. When the controller 82 determines that the sub door opening switch 66 has been operated, the flow proceeds to step S12. On the other hand, when the control unit 82 does not determine that the sub door opening switch 66 has been operated, the operation flow ends. The smart ECU 83 may determine whether or not the sub door operation acceptance signal is directly input from the sub door opening switch 66 instead of or in combination with the input of the sub door operation detection signal.

  Step S12 corresponds to step S02 shown in FIG. 7A, step S13 corresponds to step S03 shown in FIG. 7A, and step S14 corresponds to step S04 shown in FIG. .

  In step S15, the controller 82 of the smart entry system switches the state of the sub door latch device 61 from the latched state to the unlatched state. Specifically, the smart ECU 83 outputs an unlatch request signal to the double door ECU 84, and the double door ECU 84 switches the sub door latch device 61 from the latched state to the unlatched state.

  Step S16 corresponds to step S06 shown in FIG. When step S16 ends, the operation flow ends. Note that the order of step S15 and step S16 may be interchanged or may be performed simultaneously.

  An operation flow when the lock switch 23 is operated by the occupant will be described with reference to FIG. Of the steps of the operation flow shown in FIG. 7C, the same operation flow as that shown in FIG. 7A or FIG. Description is omitted.

  In step S21, the control unit 82 of the smart entry system determines whether or not the lock switch 23 has been operated by an occupant. Specifically, the smart ECU 83 determines whether or not a lock operation acceptance signal has been input from the lock switch 23. When the controller 82 determines that the lock switch 23 has been operated, the flow proceeds to step S22. On the other hand, when the control unit 82 does not determine that the lock switch 23 has been operated, the operation flow ends.

  Step S22 corresponds to step S02 shown in FIG. 7A and step S12 shown in FIG. 7B, and step S23 is shown in step S03 shown in FIG. 7A and FIG. 7B. Corresponding to step S13, step S24 corresponds to step S04 shown in FIG. 7A and step S14 shown in FIG. 7B.

  In step S25, the controller 82 of the smart entry system switches the state of the side door door lock device 22 from the unlocked state to the locked state. Specifically, the smart ECU 83 outputs a lock request signal to the door lock control ECU 85, and the door lock control ECU 85 is at least one of the side door door lock devices 22 provided in each of the side doors 21, 21, 21, 21. One (preferably all) state is switched from the unlocked state to the locked state. When step S25 ends, the operation flow ends.

  Each operation flow shown in FIGS. 7A, 7B, and 7C has been described separately, but actually, the operation flows are executed in parallel.

2. Example 2
2-1. Configuration of vehicle with double doors Embodiment 2 is a vehicle 10A in which a door lock mechanism is added to the double door 70 of the vehicle 10 described in the first embodiment. That is, in the description of the second embodiment, only the configuration different from that of the vehicle 10 of the first embodiment will be described. Hereinafter, the configuration of the vehicle 10A will be described with reference to FIG.

  In the vehicle 10 of the first embodiment, the back door latch device 41 is configured by an electromagnetic mechanism that electromagnetically switches between the latched state and the unlatched state. However, in the vehicle 10A of the second embodiment, the backdoor latch device 41 is mechanically in the latched state. You may be comprised with the mechanical mechanism in which an unlatch state switches.

  When the back door latch device 41 is configured by a mechanical mechanism, the back door handle 43 is rotated by, for example, an occupant to switch the state of the back door latch device 41 from the latched state to the unlatched state. It is mechanically connected to the back door latch device 41.

  The back door 40 further includes a back door lock device 47 for switching between a locked state and an unlocked state. The locked state is a state in which switching of the back door latch device 41 from the latched state to the unlatched state is prohibited. The unlocked state is a state in which switching of the back door latch device 41 from the latched state to the unlocked state is not prohibited.

  In the second embodiment, the openable state of the back door 40 means that the back door latch device 41 is switched from the latched state to the unlatched state, and the back door door lock device 47 is changed from the locked state to the unlocked state. This includes the switched state.

  In the vehicle 10 of the first embodiment, the sub-door latch device 61 is configured by an electromagnetic mechanism that electromagnetically switches between the latched state and the unlatched state. However, in the vehicle 10A of the second embodiment, mechanically latched and unlatched. You may be comprised with the mechanical mechanism in which a state switches.

  When the sub-door latch device 61 is constituted by a mechanical mechanism, the sub-door outer handle 63 and the sub-door inner handle (not shown) are rotated by, for example, an occupant, and the state of the sub-door latch device 61 is Is mechanically connected to the sub door latch device 61 so as to be switchable from the latched state to the unlatched state.

  The sub door 60 includes a sub door door lock device 67 for switching between a locked state and an unlocked state. The locked state is a state in which switching from the latched state to the unlatched state of the sub door latch device 61 is prohibited. The unlocked state is a state in which switching of the sub door latch device 61 from the latched state to the unlocked state is not prohibited.

  In the second embodiment, the openable state of the sub door 60 means a state in which the sub door latch device 61 is switched from the latched state to the unlatched state, and the sub door door lock device 67 is switched from the locked state to the unlocked state. It is.

2-2. Configuration and Operation of Smart Entry System FIG. 9 shows a smart entry system applied to the vehicle 10A in the second embodiment. The smart entry system for the vehicle 10A according to the second embodiment may not include the double door ECU 84. That is, the back door opening switch 46 outputs, for example, a back door operation acceptance signal to the smart ECU 83 via the hard wire 92a when an operation by the occupant is performed on the back door opening switch 46. Further, the sub door opening switch 66 outputs, for example, a sub door operation acceptance signal to the smart ECU 83 via the hard wire 92a when an operation by the occupant is performed on the sub door opening switch 66.

  The door lock control ECU 85 is further connected to at least one (preferably both) of the back door door lock device 47 and the sub door door lock device 67 by, for example, a hard wire 92c.

  In the first embodiment, the double door ECU 84 detects the states of the back door latch device 41 and the sub door latch device 61. However, in the second embodiment, the door lock control ECU 85 is connected via, for example, the hard wire 92c. The states of the back door latch device 41 and the sub door latch device 61 are detected. The smart ECU 83 detects the states of the back door latch device 41 and the sub door latch device 61, and the back door door lock device 47 and the sub door door lock device 67 from the door lock control ECU 85 via the CAN 91. In the smart ECU 83, the back door latch device 41 and the sub door latch device 61 are in the latched state, the back door door lock device 47 and the sub door door lock device 67 are in the locked state, and the back door operation is performed. When a reception signal or a subdoor operation reception signal is input, a predetermined signal is transmitted from the antenna 81.

  In the first embodiment, after the smart ECU 83 inputs the back door operation detection signal or the subdoor operation detection signal, the smart ECU 83 unlatches via the CAN 91 when it is determined that the ID information included in the response signal matches its own ID information. A request signal is output to the double door ECU 84. However, in the second embodiment, when the smart ECU 83 determines that the ID information included in the response signal matches its own ID information after inputting the back door operation acceptance signal or the subdoor operation acceptance signal, the smart ECU 83 passes the CAN 91. The unlock request signal is output to the door lock control ECU 85.

  When the door lock control ECU 85 receives the unlock request signal, the door lock device 22 for the side door, the door lock device 47 for the back door, and the door lock for the sub door provided in each of the side doors 21, 21, 21, and 21. At least one (preferably all) state of the device 67 is switched from the locked state to the unlocked state.

  Similarly, when the lock switch 23 is operated by the occupant, the smart ECU 83 determines that when the back door latch device 41 and the sub door latch device 61 are in the latched state and the lock operation acceptance signal is input, A predetermined signal is transmitted from the antenna 81.

  When the door lock control ECU 85 receives a lock request signal, the door lock device 22 for the side door, the door lock device 47 for the back door, and the door lock device for the sub door provided in each of the side doors 21, 21, 21, 21. At least one (preferably all) of 67 is switched from the unlocked state to the locked state.

  The back door opening switch 46 is also connected to the back door latch device 41 by, for example, a hard wire 92d. When the back door opening switch 46 is operated by the occupant, the state of the back door latch device 41 is switched from the latched state to the unlatched state without being controlled by the smart ECU 83. However, when the back door door lock device 47 is in the locked state, the back door latch device 41 is prohibited from switching from the latched state to the unlatched state.

  Similarly, the sub door opening switch 66 is also connected to the sub door latch device 61 by, for example, a hard wire 92e. When the sub door opening switch 66 is operated by an occupant, the state of the sub door latch device 61 is switched from the latched state to the unlatched state without being controlled by the smart ECU 83. However, when the state of the sub door door lock device 67 is the locked state, the state of the sub door latch device 61 is prohibited from switching from the latched state to the unlatched state.

  Here, in the second embodiment, each of the back door opening switch 46 and the sub door opening switch 66 may have the function of the lock switch 23. However, when the vehicle 10A is provided with the common lock switch 23 as shown in FIG. 8, each of the back door opening switch 46 and the sub door opening switch 66 has a function of enabling the opening.

  The operation of the vehicle 10A to which the smart entry system is applied will be described using the flowcharts shown in FIGS. 10 (A) and 10 (B). In the description of the flowchart shown in FIG. 10 (A) and FIG. 10 (B), the same part as the description of the flowchart shown in FIG. 7 (A), FIG. 7 (B), or FIG. Detailed description is omitted.

  An operation flow when the back door opening switch 46 or the sub door opening switch 66 is operated by the occupant will be described with reference to FIG. In step S101, the control unit 82 of the smart entry system determines whether the back door opening switch 46 or the sub door opening switch 66 has been operated by the occupant. Specifically, the smart ECU 83 determines whether or not the back door operation reception signal or the sub door operation reception signal is directly input from the back door opening switch 46 or the sub door opening switch 66. When the controller 82 determines that the back door opening switch 46 or the sub door opening switch 66 has been operated, the flow proceeds to step S102. On the other hand, when the control unit 82 does not determine that the back door opening switch 46 or the sub door opening switch 66 is operated, the operation flow ends.

  Step S102 corresponds to step S02 in the first embodiment shown in FIG. 7A, step S103 corresponds to step S03 in the first embodiment shown in FIG. 7A, and step S104 corresponds to FIG. This corresponds to step S04 in the first embodiment shown in FIG.

  In step S105, the control unit 82 of the smart entry system switches the state of the door lock device 22 for the side door, the door lock device 47 for the back door, and the door lock device 67 for the sub door from the locked state to the unlocked state. Specifically, the smart ECU 83 outputs an unlock request signal to the door lock control ECU 85, and the door lock control ECU 85 includes the side door door lock device 22 provided in each of the side doors 21, 21, 21, 21. At least one (preferably all) state of the back door lock device 47 and the sub door lock device 67 is switched from the locked state to the unlocked state. When step S105 ends, the operation flow ends.
