  FIG. 1 is a block diagram showing a configuration of a vehicle door control device according to an embodiment of the present invention.

  The vehicle door control device A according to this embodiment includes a control unit 11 that individually controls opening and closing of doors 2 (2a to 2e) that can automatically open and close the vehicle, and an opening and closing lever 3 (3a to 3e) provided on the door 2. Opening / closing detection unit 12 for detecting opening / closing of the door 2 by an operation, and locking / unlocking detection unit for detecting locking / unlocking by an operation of a knob (hereinafter also referred to as a door knob) 4 (4a to 4e) provided on the door 2 13. Detection unit 14 that detects that the user of the vehicle has approached the stopped vehicle, communication unit 15 that communicates with the electronic key 5 for the vehicle, timer unit 16 that measures a predetermined time, an electronic sound, etc. The notification part 17 grade | etc., To be comprised is comprised. Also connected to the vehicle door control device A are a door drive mechanism 21 that individually opens and closes each door 2 and a lock mechanism 22 that locks and unlocks the knob 4 provided on each door 2. Has been.

  The door 2 includes a driver seat side door 2a, a passenger seat side door 2b, a driver seat rear side slide door 2c, a passenger seat rear side slide door 2d, and a repellent back door 2e. Opening / closing levers 3a to 3e and door knobs 4a to 4e are provided.

  Here, the door 2 controlled to be opened and closed by the control unit 11 is basically the rear door slide doors 2c and 2d, but in addition, the back door 2e and the driver and passenger doors 2a and 2b are also used. Even if it exists, if it has the mechanism which opens automatically, it can be made into the control object in the vehicle door control apparatus A of this invention.

  Moreover, the detection part 14 comes to detect that the user is approaching a vehicle (namely, being in the detection range of the electromagnetic wave of the electronic key 5) by communication with the electronic key 5 by the communication part 15. Yes.

  When the door 2 is closed by the operation of the opening / closing lever 3 of the door 2 in a state where the door 2 is locked by the operation of the knob 4, the control unit 11 then causes the detection unit 14 to approach the user. Is detected, the door 2 is unlocked and the door 2 is controlled to open. In the following description, an operation mode in which a series of operations for opening the door as well as unlocking when the user approaches is referred to as an open mode.

  Next, automatic opening operation (open mode) reservation setting and automatic opening operation control processing by the vehicle door control device A having the above-described configuration will be specifically described with reference to the flowchart shown in FIG. However, this embodiment demonstrates the case where open mode is applied to a slide door.

  The setting of the open mode is performed in a state where the vehicle is stopped. For example, it is set when parking in a shopping center parking lot and getting off the car.

  First, the control unit 11 checks whether or not the slide door is set to the open mode (that is, whether or not the open mode is off) (step S1).

  As a result, when the open mode is not set (when YES is determined in step S1), it is next confirmed whether or not the door knobs 4c and 4d of the slide doors 2c and 2d are locked (step S2). ).

  As a result, for example, when the door knob 4d of the slide door 2d on the rear side of the passenger seat is locked by a passenger or the like (when it is determined YES in Step S2), the flag of the door knob 4d is set to 1 (Step S2). S3). On the other hand, if the door knob 4d of the slide door 2d is not locked (NO is determined in step S2), the flag of the door knob 4d is set to 0 (step S4). That is, the flag remains 0.

  Thereafter, the control unit 11 confirms whether or not all the doors have been locked at the same time by, for example, operating a digital key by a user as a driver (step S5).

  As a result, when the simultaneous lock is not performed (determined as NO in step S5), the process returns to step S1 to check the on / off state of the open mode.

  On the other hand, when the simultaneous lock is performed (when YES is determined in step S5), the flag of the door knob is confirmed (step S6). As a result, when the flag of one or a plurality of door knobs is set to 1 (when it is determined YES in step S6), the sliding door 2d of the door knob 4d with the flag 1 set is opened. (Set to ON) (step S7), the process returns to step S1. That is, reservation setting for the automatic opening operation of the sliding door 2d is performed.

  After this, the user who is the driver and his passenger leave the car and go to a shopping center, for example.

  On the other hand, since the control unit 11 is set to the open mode (that is, NO is determined in step S1), the control unit 11 continuously monitors the presence or absence of an unlock signal from the electronic key 5 (step S8), It is monitored whether the key (remote control) 5 is detected (step S9). In short, it is monitored whether a user or the like who possesses the electronic key 5 is in the detection area of the car.

  In this monitoring state, when the control unit 11 receives an unlock signal from the electronic key 5 (when it is determined YES in step S8), the control unit 11 determines that the unlocking operation is normal, and the lock mechanism unit 22 is operated. Control is performed to unlock all the doors 2 (2a to 2e), the set open mode of the slide door 2d is released (that is, off) (step S19), and the process is terminated.

  On the other hand, when a user (driver) or the like who possesses the electronic key 5 returns to the vehicle without performing the unlocking operation of the electronic key 5, the control unit 11 communicates with the electronic key 5 to perform the electronic key. 5 is detected (YES in step S9), the notification unit 17 is controlled to notify a buzzer sound such as “beep” (step S10), and the timer unit 16 starts measuring a predetermined time. (Step S11). For example, 5 seconds can be set as the predetermined time.

  Thereafter, the control unit 11 monitors whether or not the user having the electronic key 5 stays in the detection area for a predetermined time (steps S12 and S13).

  As a result, when the user who has the electronic key 5 goes out of the detection area before the predetermined time elapses (when NO is determined in step S12), the count of the timer unit 16 is cleared (step S17). ), The process returns to step S8. In other words, the user who has returned to the car may leave the car again for some reason (go out of the detection area) before the predetermined time elapses, so it is not preferable to execute the open mode in such a case. Because.

  On the other hand, if the user unlocks the electronic key 5 and transmits an unlock signal before the predetermined time has elapsed (NO in step S13, YES in step S18), the control unit 11 It is determined as a normal unlocking operation, the lock mechanism unit 22 is controlled to unlock all the doors, the set open mode of the slide door 2d is released (that is, turned off) (step S19), and the process is performed. finish.

  On the other hand, when the user holding the electronic key 5 stays in the detection area for a predetermined time (YES in step S12, YES in step S13), the control unit 11 controls the lock mechanism unit 22. All the doors 2 are unlocked (step S14), and the sliding door 2d for which the open mode is set continues to control the door drive mechanism 21 to open the sliding door 2d (step S15). Finally, all flags are initialized (set to 0) (step S16), and the process ends.

  In the above embodiment, when the user who possesses the electronic key 5 enters the detection area in step S12, the predetermined time is measured in step S13. However, the processing in step S13 is eliminated, and the electronic When the user having the key 5 enters the detection area, all the doors 2 are unlocked (step S14), and the sliding door 2d for which the open mode is set continues to open the sliding door 2d. May be performed (step S15).

  Further, in the above embodiment, when the door knob 4d of the slide door 2d is locked in step S2, and the doors 4d are simultaneously locked by the operation of the electronic key 5 in step S5, the slide door 2d is set to the open mode. Even if the passenger closes the slide doors 2c, 2d by operating the open / close levers 3c, 3d with the door knobs 4c, 4d of the slide doors 2c, 2d locked, the slide door 2c, You may comprise so that 2d may be set to an open mode. In other words, the door open mode may be individually set by the combination of the knob 4 and the opening / closing lever 3 instead of the simultaneous lock of all the doors by the operation of the electronic key 5.
