(First embodiment)
FIG. 1 is a block diagram showing a schematic configuration of a vehicle door control system 1 according to the first embodiment. As shown in FIG. 1, the vehicle door control system 1 includes a portable device 2 and a vehicle door control device 10.

  The portable device 2 is also referred to as an electronic key and is carried by a vehicle driver or the like. The portable device 2 stores in advance unique identification information (key) assigned to the vehicle, and can wirelessly communicate with the vehicle door control device 10.

  The vehicle door control device 10 is mounted on a vehicle having a plurality of vehicle doors that automatically open and close, and controls opening and closing of the vehicle doors. The plurality of vehicle doors that automatically open and close includes left and right sliding doors and a back door. The slide door is also called a power slide door, and the back door is also called a power back door. The vehicle also has a vehicle door that is manually opened and closed without being automatically opened and closed, and such a vehicle door includes a vehicle door for a driver seat and a vehicle door for a passenger seat.

  The vehicle door control device 10 includes a reception unit 12, a verification ECU 14, a communication unit 16, a body ECU 18, an acquisition unit 20, a door lock mechanism 22, a right slide door ECU 24, a left slide door ECU 26, a back And a door ECU 28.

  The receiving unit 12 receives an operator's closing operation of the vehicle door. The reception unit 12 includes a door lock switch that receives the closing operation, and the door lock switch is provided on each of the door handle of the driver seat and the door handle of the passenger seat. The closing operation is a single operation of the door lock switch, for example, a long press of the door lock switch. The vehicle door control device 10 performs door locking when the period during which the door lock switch is pressed is relatively short. When the door lock switch is pressed for a relatively long period of time, that is, when the door lock switch 10 is pressed for a long time, the vehicle door control device 10 automatically locks all the vehicle doors that are automatically opened and closed while locking the door. Close to. The door lock switch outputs an operation signal to the verification ECU 14 while being pressed by the operator.

  The accepting unit 12 may include a door lock touch sensor that outputs an operation signal to the verification ECU 14 while being touched by the operator instead of or in addition to the door lock switch. The function of the touch sensor is the same as that of the door lock switch, and the closing operation is, for example, a long press of the touch sensor.

  The verification ECU 14 includes an operation determination unit 30 and a verification unit 32. Based on the operation signal output from the reception unit 12, the operation determination unit 30 determines whether the reception unit 12 has received a closing operation, that is, whether the door lock switch has been pressed for a long time.

  When it is determined by the operation determination unit 30 that the door lock switch has been pressed for a long time, the verification unit 32 performs key verification for confirming whether the operation is an authorized user operation. For this purpose, the verification unit 32 causes the communication unit 16 to transmit a radio wave in a predetermined first frequency band (for example, an LF (Low Frequency) band) including a request signal for requesting a response from the portable device 2.

  When the portable device 2 acquires the request signal from the radio wave transmitted from the communication unit 16, the mobile device 2 transmits a radio wave in a predetermined second frequency band (for example, an RF (Radio Frequency) band) including the stored unique identification information. To do. The communication unit 16 acquires identification information from the radio wave transmitted from the portable device 2 and notifies the verification unit 32 of the identification information.

  The collation unit 32 collates whether the identification information notified from the communication unit 16 is genuine. If the identification information is regular, that is, if key collation is established, a one-motion close operation intention detection signal (hereinafter, detection) (Referred to as a signal) is transmitted to the body ECU 18 using communication such as CAN (Controller Area Network).

  The acquisition unit 20 includes a plurality of vehicle doors that are manually opened and closed, and a courtesy switch provided in each of the plurality of vehicle doors that are automatically opened and closed, and acquires the open / closed state of the vehicle doors.

  The body ECU 18 includes a lock control unit 40 and a closing control unit 42. The lock control unit 40 activates the door lock mechanism 22 when a detection signal is received from the verification unit 32, that is, when the closing operation is received by the receiving unit 12 and the operation of a regular user is confirmed, A plurality of manually opened / closed vehicle doors and a plurality of automatically opened / closed vehicle doors are locked. When the door lock mechanism 22 is activated, the opened vehicle door is locked when the door is closed.

  The closing control unit 42 is in the open state by the acquisition unit 20 when a detection signal is received from the verification unit 32, that is, when a closing operation is received by the receiving unit 12 and an authorized user operation is confirmed. All of the plurality of vehicle doors that are automatically opened and closed that have been acquired are closed and controlled based on a predetermined priority order. When there is one vehicle door that is automatically opened and closed, which is acquired by the acquisition unit 20 to be in the open state, the closing control unit 42 controls the vehicle door to be closed. The closing control unit 42 transmits a closing instruction to the corresponding one of the right sliding door ECU 24, the left sliding door ECU 26, and the back door ECU 28 corresponding to the vehicle door to be closed using communication by CAN or the like.

  The priority order of the slide door on the side opposite to the operator is higher than the priority order of the slide door on the operator side. When an operation signal is output from the driver's door lock switch, the closing control unit 42 determines that the operator-side slide door is the right slide door, and an operation signal is output from the passenger's door lock switch. In such a case, it is determined that the slide door on the operator side is the left slide door.

  The priority order of the back doors is determined in advance, and is higher than the priority order of the left and right sliding doors in this embodiment. However, the priority order of the back door is not limited to this example, and may be lower than the priority order of the left and right sliding doors, or lower than the priority order of the sliding door on the opposite side to the operator, and the operator. It may be higher than the priority of the sliding door on the side.

  The right slide door ECU 24 controls a right slide door drive unit (not shown) that drives the right slide door to control automatic opening and closing of the right slide door. When the right sliding door ECU 24 receives the closing instruction from the closing control unit 42, the right sliding door ECU 24 closes the right sliding door if the closing operation condition is satisfied. The closing operation condition is, for example, that the door lock by the door lock mechanism 22 is operating normally.

  The left slide door ECU 26 controls a left slide door drive unit (not shown) that drives the left slide door to control automatic opening and closing of the left slide door. When the closing instruction is received from the closing control unit 42, the left sliding door ECU 26 closes the left sliding door if the closing operation condition is satisfied.

  The back door ECU 28 controls a back door drive unit (not shown) that drives the back door to control automatic opening / closing of the back door. When the back door ECU 28 receives a closing instruction from the closing control unit 42, the back door ECU 28 closes the back door if the closing operation condition is satisfied.

  Each ECU such as the collation ECU 14 includes a computer, and various functions of each ECU such as the collation ECU 14 can be configured by a circuit block, a memory, and other LSIs in terms of hardware. Realized by a loaded program. Accordingly, it is understood by those skilled in the art that various functions of each ECU such as the verification ECU 14 can be realized in various forms only by hardware, only by software, or a combination thereof, and is not limited to any one. .

  FIG. 2 is a flowchart regarding the operation of the door lock switch on the driver's seat side in the vehicle door control system 1 of FIG. In FIG. 2, the right sliding door, that is, the sliding door on the driver's seat side is represented as “PSDR”, the left sliding door, that is, the sliding door on the passenger seat side is represented as “PSDL”, and the back door is represented as “PBD”. .

  First, when a driver's side door lock switch is long pressed by an operator outside the vehicle (S10), the collation unit 32 determines whether key collation is established (S12). If the key verification is not established (N in S12), the process returns to S10. When the key verification is established (Y in S12), the lock control unit 40 locks the door and answers the operator by lighting a hazard lamp or a buzzer sound (S14), and then the closing control unit 42 The opening / closing state of the vehicle door acquired by the acquisition unit 20 is confirmed (S16).

  As a result of the confirmation in S16, the closing control unit 42 ends the process when the function stop operation is performed by the operator or when all the doors are in the closed state. The function stop operation is, for example, an operation in which a closed vehicle door is opened by an operator or the like, an operation of a door lock switch by an operator again, or an operation of an unlock switch provided on a door handle by an operator. Including. When all the doors are in the closed state, all the doors are locked simply by pressing the door lock switch of the door handle from the outside of the vehicle, so-called smart door lock is performed.

  As a result of the confirmation in S16, when the back door is in the open state, the closing control unit 42 starts the closing operation of the back door regardless of the open / closed state of the left and right slide doors (S18). That is, when the sliding door is in the open state, the start of the closing operation of the back door has priority over the start of the closing operation of the sliding door.

  Next, the closing control unit 42 checks the open / closed state of the vehicle door (S20), and if the left slide door or the right slide door is open, waits for a predetermined time (S22) and returns to S16. The predetermined time is not particularly limited, and an optimum value can be obtained through experiments or the like, and may be, for example, 1 second or less, or 0.5 seconds. By waiting for a predetermined time in S22, the closing control unit 42 controls closing of the plurality of vehicle doors that are automatically opened and closed with a time difference.

  In S20, if the left sliding door and the right sliding door are in the closed state or in the closing operation, the process proceeds to S28 described later.

  As a result of the confirmation in S16, the closing control unit 42 determines that the operation is performed when the left sliding door, which is the sliding door opposite to the operator, is in the open state and the back door is in the closed state or in the closing operation. Regardless of the open / closed state of the right slide door, which is the person-side slide door, the closing operation of the left slide door is started (S24). That is, when the slide door on the operator side is in the open state, the start of the closing operation of the slide door on the side opposite to the operator has priority over the start of the closing operation of the slide door on the operator side. After S24, the process proceeds to S20.

  As a result of the confirmation in S16, the closing control unit 42 indicates that the right sliding door is in the open state, the left sliding door is in the closed state or in the closing operation, and the back door is in the closed state or the closing operation. If there is, the closing operation of the right sliding door is started (S26). Next, the closing control unit 42 confirms whether all the doors are in the closed state at the timing when the left and right sliding doors and the back door are scheduled to be in the closed state upon completion of the closing operation (S28).

  As a result of the confirmation in S28, the closing control unit 42 ends the process when a function stop operation is performed by an operator or the like. The function stop operation includes, for example, an operation in which the door being closed is forcibly stopped by an operator or the like in addition to the above-described operation.

  On the other hand, if all the doors are in the closed state as a result of the confirmation in S28, the closing control unit 42 confirms whether or not the portable device 2 is in the vehicle interior using the matching unit 32 and the communication unit 16 (S30). If there is no 2 (N in S30), the process is terminated. When there is the portable device 2 in the vehicle interior (Y in S30), the closing control unit 42 performs a process for preventing the portable device 2 from being closed, specifically, unlocks (S32), and ends the processing. As a situation where the portable device 2 is in the vehicle interior in S30, it is conceivable that the operator places the portable device 2 in the vehicle interior after the key verification in S12.

  If the door lock switch on the passenger seat side is operated, the same processes as those in the above flowchart are performed except for the following three processes. That is, in S10, if the passenger side door lock switch is pressed for a long time, the process proceeds to S12. As a result of the confirmation in S16, the closing control unit 42 determines that the right sliding door, which is the sliding door on the side opposite to the operator, is in the open state and the back door is in the closed state or in the closing operation, S24. To start closing the right sliding door. As a result of the confirmation in S16, the closing control unit 42 indicates that the left slide door is in the open state, the right slide door is in the closed state or in the closing operation, and the back door is in the closed state or the closing operation. If there is, the closing operation of the left sliding door is started in S26.

  As described above, according to the present embodiment, a plurality of vehicle doors that are automatically opened and closed are controlled to be closed with a time difference based on a predetermined priority order, so that a plurality of automatic doors can be opened and closed by an operator outside the vehicle. It is possible to easily confirm the closing operation of the vehicle door visually.

  In addition, since the sliding door on the operator side starts closing after the start of the closing operation on the side opposite to the operator, the operator outside the vehicle can close the sliding door on the side opposite to the operator. When viewing the screen, it is difficult for the operator to block the view by the sliding door on the operator side. Therefore, it is possible to easily make the operator visually confirm the closing operation of the slide door on the side opposite to the operator.

  In addition, when the door lock switch is closed once, all the sliding doors and back doors in the open state are automatically closed and the door can be locked. Therefore, convenience can be improved.
