Description

  The present invention relates to a control device for a vehicle sliding door that opens a sliding door in conjunction with an opening operation of a front door.

  Conventionally, some vehicles such as wagon cars and one-box cars have adopted sliding doors on the rear seat side for the purpose of facilitating passengers to get on and off. Since a large force is required, a power sliding door that is opened and closed using a driving source such as a motor is known.

  In this type of vehicle, the front door is a hinged door, and the center pillar (also referred to as “B-pillar”) between the rear-side power slide door is abolished and the so-called pillar-less vehicle is improved. Is also known.

For example, in Patent Document 1 (Japanese Utility Model Publication No. 6-3713), in a pillarless vehicle having a slide door on the rear side, when the slide door is moved to an open state, the movement is detected by a switch, and the front door is moved by a motor. Techniques for operating in an open state are disclosed.

FIG. 1 is a schematic perspective view of a one box car provided with a power slide door, FIG. 2 is a schematic plan view of a one box car with a roof omitted, and FIG. 3 is a schematic configuration diagram of a control device for a vehicle slide door. It is shown.

  As shown in FIG. 1 and FIG. 2, a one-box car 1 as an example of a vehicle is a front door that is pivotally supported at front portions on both sides of a vehicle body 1a and pivotally pivoted to the vehicle body 1a via hinges. 6L, 6R are provided, and a left power slide door 7L and a right power slide door 7R are provided at the rear of both sides of the vehicle body 1a. Each of the power slide doors 7L and 7R is an electric slide door, and a door drive unit 8 having a motor 8a as a drive source is connected to each of the power slide doors 7L and 7R (see FIG. 3).

  The vehicle body 1a has a so-called pillarless structure in which the center pillar (also referred to as “B-pillar”) is abolished. When the front doors 6L and 6R and the power slide doors 7L and 7R are both opened, The front opening 1b that is opened and closed by the front doors 6L and 6R and the rear opening 1c that is opened and closed by the power slide doors 7L and 7R are connected to the side to secure a wide opening 1d. By securing a wide opening 1d on the side of the vehicle body 1a, it is easy to get on and off the front seat as well as to get on and off the rear seat.

  Here, the support structure of the power slide doors 7L and 7R will be briefly described. The power slide doors 7L and 7R have front and lower upper and lower portions provided respectively at the upper and lower parts of the vehicle body 1a and extending forward and backward via an upper arm 11a and a lower rail 11b via an upper arm 12a and a lower arm 12b. It is supported. A center rail 13 provided on the inner surfaces of the power slide doors 7L and 7R and extending in the front-rear direction is supported by a center arm 14 provided on a side portion of the vehicle body 1a. Although FIG. 1 shows the support structure for the left power slide door 7L, the support structure for the right power slide door 7R has a symmetric configuration with the left power slide door 7L. Is omitted. The power slide doors 7L and 7R are guided by the rails 10, 11, and 13 so as to be movable in the front-rear direction of the side surface of the vehicle body 1a.

  A touch sensor 21 is provided at the front end of each power slide door 7L, 7R. The touch sensor 21 detects that a foreign object or the like has been caught at the front end of the door when the power slide doors 7L and 7R are closed, and has a flexible protector (not shown) such as soft resin or rubber. ). When the power slide door 7L or 7R is being closed, if a foreign object or the like is sandwiched between the front door 6L or 6R, the touch sensor 21 is turned on to stop the power slide door 7L or 7R and then open. Be operated.

  2 denotes a fuel lid, which is provided on the right rear side surface of the vehicle body 1a in this embodiment. Reference numeral 19 denotes a door outer handle provided in the front doors 6L and 6R, and 20 denotes a power slide door (PSD) outer handle provided in the power slide doors 7L and 7R.

  Each front door 6L, 6R and each power slide door 7L, 7R is provided with a door lock mechanism (not shown), and the lock portion of each door lock mechanism is a door lock actuator shown in FIG. 26 is used to lock / unlock. Although only one door lock actuator 26 is shown in FIG. 3 for convenience, the door lock actuator 26 is provided in all the doors 6L, 6R, 7L, 7R.

  Locking / unlocking of each door 6L, 6R, 7L, 7R and automatic opening / closing operation of each power slide door 7L, 7R are controlled by a control unit (ECU) 9 as a control means mounted on the one-box car 1. Is done.

  The control unit 9 is mainly composed of a computer (microcomputer) provided with a well-known CPU, ROM, RAM (all not shown) and the like, and a door remote control transmitter (to be described later) (hereinafter referred to as a remote controller transmitter) to be described later. (Referred to as “door remote control”) 15, which detects the opening / closing of the remote control receiver 9 a that receives a signal transmitted wirelessly, the touch sensor 21, and each of the doors 6 L, 6 R, 7 L, and 7 R, and performs an ON operation in the open state. , Door switch 22 as a door opening / closing detection means, and a door lock switch that detects lock / unlock of the door lock mechanism provided in each door 6L, 6R, 7L, 7R and outputs an ON signal in the unlocked state 23, power slide door (PSD) half open detection switch 24 for detecting the half open state of the power slide doors 7L, 7R, power slice Such as power sliding door (PSD) fully open detection switch 25 for detecting the door 7L, the fully opened state of the 7R are connected.

  The door switch 22 and the door lock switch 23 are provided for each door 6L, 6R, 7L, 7R. The PSD half-open detection switch 24 and the PSD full-open detection switch 25 are provided for each of the power slide doors 7L and 7R. The PSD half-open detection switch 24 is configured by a limit switch or the like. For example, the PSD half-open detection switch 24 is provided in the middle of any one of the rails 10, 11, and 13, and the PSD half-open detection is performed while the power slide doors 7L and 7R are opened. When the switch 24 passes through the center arm 14, it is turned on. In this case, the opening amounts of the power slide doors 7L and 7R are read by an encoder and a Hall IC installed in the drive motor, and the power slide doors 7L and 7R are opened to a preset position based on the read values. Since the PSD half-opening detection switch 24 is not necessary in the case of the above-described configuration, the half-open position may be detected by a signal from an encoder or a Hall IC instead of the PSD half-opening switch 24.

  On the other hand, a door drive unit 8, a door lock actuator 26, a buzzer 27, and the like are connected to the output side of the control unit 9.

  In FIG. 3, only one touch sensor 21, switches 22 to 25, door drive unit 8, door lock actuator 26, and buzzer 27 are shown for convenience, but as described above, the door switch 22, door lock, The switch 23 and the door lock actuator 26 connected to the output side are provided for each door 6L, 6R, 7L, 7R. Further, the touch sensor 21, the PSD half-open detection switch 24, the PSD full-open detection switch 25, the output-side door drive unit 8, and the buzzer 27 are provided for each of the power slide doors 7L and 7R. Although not shown, an operation switch for opening and closing the power slide doors 7L and 7R is disposed at a position where the driver can operate, such as the instrument panel 2.

  The door remote controller 15 transmits a radio signal for remotely controlling the operations of the door driving unit 8 and the door lock actuator 26 to the remote control receiving unit 9a. The operation switch serving as a selection unit includes a lock switch 16L and an unlocking unit. A switch 16U is provided, and a left slide door switch 17L that operates an automatic opening / closing operation of the left power slide door 7L and a right slide door switch 17R that operates an automatic opening / closing operation of the right power slide door 7R are provided. In many cases, the door remote controller 15 is integrally assembled with the ignition key.

  When the remote control receiver 9a receives the lock signal (or unlock signal) from the lock switch 16L (or unlock switch 16U) provided on the door remote controller 15, the control unit 9 receives all the doors 6L, 6R, 7L. , 7R are driven to lock (unlock) the locking mechanisms provided at the same time. When the ON signal is received from one of the slide door switches 17L and 17R, the power slide door 7L (or 7R) on the side where the ON signal is output is fully opened. If the slide door switch 17L (or 17R) is turned on while the power slide door 7L (or 7R) is fully opened, the power slide door 7L (or 7R) is closed.

  Further, in this embodiment, when the unlock switch 16U of the door remote controller 15 is turned on and then one of the front doors 6L and 6R is opened, in conjunction with this, the power slide door 7L ( Alternatively, 7R) is automatically half-opened. Since the vehicle body 1a employed in this embodiment has a pillarless structure, the power slide door 7L (or 7R) is operated halfway in conjunction with the opening operation of the front door 6L (or 6R), so that the ride on the front seat is Of course, it is easy to get on the rear seat.

  The operation control of the power slide door 7L (or 7R) executed by the control unit 9 is processed according to the power slide door (PSD) opening / closing control routine shown in FIG. This routine is started when an ON signal is received from any of the switches 16U, 16L, 17L, and 17R of the door remote controller 15. In the following, the operation when the right front door 6R is opened will be described, and the operation when the left front door 6L is opened will be described with reference numerals of related components in parentheses. Is omitted.

  When the passenger turns on any of the switches 16U, 16L, 17L, and 17R of the door remote controller 15, first, in step S1, whether or not the front doors 6L and 6R are in a closed state is determined. A check is made based on the state of the door switch 22 connected to each of the 6Rs. If any of the door switches 22 connected to the front doors 6L and 6R is ON, the process jumps to step S9, clears the count value n of the counter (n ← 0), and exits the routine. When both the door switches 22 connected to the front doors 6L and 6R are both OFF, that is, when both the front doors 6L and 6R are closed, the process proceeds to step S2.

  In step S2, it is checked whether or not the received signal is an unlock signal that is output when the unlock switch 16U is turned on. If not, the process jumps to step S9 to clear the count value n of the counter. (N ← 0) and exit the routine. If the signal is an unlock signal, the process proceeds to step S3, and the door lock actuator 26 provided in the lock mechanism of each door 6L, 6R, 7L, 7R is driven to move all the doors 6L, 6R, 7L, 7R. The process proceeds to step S4.

  In step S4, it is determined in steps S4 to S7 whether or not the power slide door 7L or 7R is half-opened. First, in step S4, the count value n of the counter for counting the number of times of receiving the unlock signal is incremented (n ← n + 1), and the process proceeds to step S5, where the count value n of the counter and the preset number of times no are set. Compare. The set number of times can be appropriately set to a value of 2 or more. In this embodiment, no = 2 is set.

When n <no, that is, when the passenger has not turned on the unlock switch 16U of the door remote controller 15 for the set number of times, the routine is exited. On the other hand, when n ≧ no, that is, when the unlock switch 16U is turned on at least the set number of times (pressed twice in this embodiment), after the counter value n is cleared in step S6 (n ← 0) The process proceeds to step S7 and waits until one of the door switches 22 connected to the front doors 6L and 6R is turned on.

  When a passenger such as a driver pulls the outer handle 19 of the front door 6R (6L) and opens the front door 6R (6L) as shown by a two-dot chain line in FIG. 2, the front door 6R (6L) ) Is turned on.

  Then, the program determines that the operation conditions are suitable, and proceeds to step S8 to execute power slide door (PSD) half-open control.

  This PSD half-open control is processed according to the PSD half-open control subroutine shown in FIG. In this subroutine, first, in step S11, the door drive unit 8 that opens and closes the power slide door 7R (7L) provided on the same side as the front door 6R (6L) where the door switch 22 is turned on is operated. Output an open signal. Then, the motor 8a provided in the door drive unit 8 moves the power slide door 7R (7L) to the rear of the vehicle body 1a as shown by the two-dot chain line in FIG.

  Next, the process proceeds to step S12, and it is checked whether or not the PSD half-open detection switch 24 has been turned ON. If it is in the OFF state, the process returns to step S11 to continue the opening operation of the power slide door 7R (7L). When the PSD half-open detection switch 24 is turned ON, the process proceeds to step S13, the operation of the door drive unit 8 is stopped, the opening operation of the power slide door 7R (7L) is stopped, and then the process proceeds to step S14. Execute the closing control and exit the routine.

  The PSD closing control executed in step S14 is processed according to the PSD closing control subroutine shown in FIG.

  In this subroutine, first, in step S16, it is determined whether or not the front door 6R (6L) is closed based on whether or not the door switch 22 on the front door 6R (6L) side is turned off. When in the open state of ON, it waits until the door switch 22 is turned off. Then, when the passenger closes the front door 6R (6L) and, as a result, the door switch 22 is turned off, the process proceeds to step S17, and whether or not the power slide door 7R (7L) is in the open state is determined. Judgment is made based on whether or not the door switch 22 on the slide door 7R (7L) side is in the ON state.

  Then, when the power slide door 7R (7L) whose door switch 22 on the power slide door 7R (7L) side is OFF is in a fully closed state, for example, a passenger who gets on the rear seat manually operates the power slide door 7R (7L). When is closed, the routine is exited.

  On the other hand, when the power slide door 7R (7L) whose door switch 22 is ON is in the open state, the process proceeds to step S18, and it is checked whether or not the subtraction timer T2 has timed up (T2 = 0). The subtraction timer T2 is set to a time limit T_over2 (for example, 30 [sec]) when the power slide door 7R (7L) stops in a half-open state (T2 ← T_over2).

  When the time is up (T2 = 0), that is, when the front door 6R (6L) is not closed within the time limit T_over2, the routine is exited. Accordingly, even if the front door 6R (6L) is subsequently closed, the power slide door 7R (7L) does not automatically close.

  On the other hand, when T2> 0, that is, when the front door 6R (6L) is closed within the time limit T_over2, the process proceeds to step S19, the subtraction timer T2 is cleared (T2 ← 0), and the process proceeds to step S20. The buzzer 27 is turned on for a set time (for example, 2 [sec]) and blown to notify the passengers that the power slide door 7R (7L) is closed.

  After that, that is, after the time required for blowing the buzzer 27 elapses, the process proceeds to step S21, and a close signal is output to the door drive unit 8 of the power slide door 7R (7L) stopped in the half-open state. Then, the power sliding door 7R (7L) is closed to exit the routine.

  As described above, in this embodiment, before the front door 6R (6L) is opened, the door remote controller 15 is operated to set the power slide door 7R (7L) in a standby state in which the half-opening operation is possible. As indicated by the dotted line, when the passenger opens the front door 6R (6L), the power slide door 7R (7L) can be naturally opened in conjunction with the opening operation. As a result, it is not necessary to widen the front door 6R (6L) or the power slide door 7R (7L) when getting on the front seat or the rear seat. Even if it is narrow, it can be easily boarded.

  In this case, for example, when the front door 6R (6L) is once closed within the time limit T_over2 and then opened again, or while the buzzer 27 is blowing, the front door 6R (6L) is opened again. Then, the subsequent automatic closing operation of the power slide door 7R (7L) may be prohibited. Further, when the front door 6R (6L) is opened again while the power slide door 7R (7L) is closing, the closing operation of the power slide door 7R (7L) may be stopped. good.

  Further, the half-open amount of the power slide door 7R (7L) can be appropriately set by moving the set position of the PSD half-open detection switch 24. In addition, by minimizing the half-open amount of the power slide door 7R (7L), it becomes difficult for the passenger compartment to be recognized from the outside through the front door 1d when getting on, and luggage placed in the passenger compartment can be removed. It can be effectively protected from theft.

  Furthermore, in this embodiment, since the door remote controller 15 installed in advance is used as it is, it is not necessary to prepare a new remote controller, and it is not necessary to add new switches on the vehicle body 1a side. This embodiment can be realized without increasing the component cost.

  Further, when the front door 6R (6L) is closed after boarding, the power slide door 7R (7L) is closed in conjunction with the front door 6R (6L), so that it is not necessary to close the power slide door 7R (7L) one by one.

  Further, in the present embodiment, the power slide door 7R is only in the case where the unlock switch 16U of the door remote controller 15 is turned on for a set number of times of two or more with the front door 6R (6L) being closed. In other words, the power sliding door 7R (7L) does not open when the operation is less than the set number of times, and therefore the intention of the passenger to perform the half opening operation of the power sliding door 7R (7L). Can be reflected. Similarly, when the front door 6R (6L) is unlocked and the front door 6R (6L) is opened without operating the unlock switch 16U of the door remote controller 15, the power slide door 7R (7L) Open operation is not performed.

  Of course, when one of the slide door switches 17L and 17R of the door remote controller 15 is turned on, the slide door switch 17L or 17R on the side that is turned on is fully opened as usual.

  In the present embodiment, the power slide doors 7L and 7R linked to the front doors 6L and 6R may be further selected depending on the number of times of operation of the unlock switch 16U. That is, for example, when the unlock switch 16U is operated twice, each power slide door 7L (7R) is half-opened in conjunction with the opening operation of each front door 6L (6R). When the unlock switch 16U is operated three times, the power slide door 7R is opened in conjunction with the opening operation of the front door 6R on the driver's seat, but the front door 6L on the passenger seat side is opened. However, the power slide door 7L is restricted so as not to be opened. On the other hand, when the unlock switch 16U is operated four times, the power slide door 7L is opened in conjunction with the opening operation of the front door 6L on the passenger seat side, but the front door 6R on the driver seat side is opened. Also, the power slide door 7R is restricted so as not to open.

  As described above, the power slide doors 7L and 7R interlocked with the front doors 6L and 6R can be selected by the number of times the unlock switch 16U is turned on, so that the front door 6L or 6R is interlocked with the opening operation. The power slide door 7L or 7R that is not desired can be selected.

  FIG. 7 shows a PSD opening / closing control routine according to the second embodiment of the present invention. In the first embodiment described above, the predetermined operation by the door remote controller 15 before opening the front door 6R (6L) is the half-open operation condition of the power slide door 6R (6L), but in this embodiment, the front door 6R is used. A predetermined operation by the door remote controller 15 after opening (6L) is defined as a half-open operation condition of the power slide door 6R (6L).

  That is, in this routine, first, in step S26, it is checked whether or not the front doors 6L and 6R are in a closed state based on the state of the door switch 22 connected to each of the front doors 6L and 6R. When any of these door switches 22 is OFF, the routine is exited.

  On the other hand, when one of these door switches 22 is turned ON, the process proceeds to step S27, and it is checked whether or not a lock signal output when the lock switch 16L provided in the door remote controller 15 is turned ON is received. When the lock signal is not received, the routine is exited.

  If the lock signal is received, it is determined that the operating conditions are met, and the process proceeds to step S28, where the above-described PSD half-open control subroutine shown in FIG. 5 is executed to exit the routine.

  Normally, the lock switch 16L is turned on when all the doors 6L, 6R, 7L, and 7R are in the closed state. Therefore, even when one of the front doors 6L and 6R is in the opened state, the lock switch 16L is operated. The normal lock operation will not be hindered.

  Thus, in this embodiment, for example, when one of the front doors 6L and 6R is opened in a parking lot or the like, the front doors 6L and 6R are opened to such an extent that the space between the adjacent vehicles is narrow and the vehicle can be boarded. If this is not possible, by turning on the lock switch 16L of the door remote controller 15, the frontage 1d can be expanded to a width that allows the passenger to get on. As a result, a smooth ride is possible.

  FIG. 8 shows a PSD opening / closing control routine according to the third embodiment of the present invention. In the second embodiment described above, when the lock signal is received during the opening operation of the front door 6R (6L), it is determined that the operation condition is satisfied. However, in this embodiment, the unlock switch 16U of the door remote controller 15 is turned on. When one of the front doors 6L and 6R is opened during the operation, it is determined that the operation condition is met.

  That is, when the passenger turns on any of the switches 16U, 16L, 17L, and 17R of the door remote controller 15, the routine is started. In step S31, it is checked whether the received signal is an unlock signal or not. If it is a signal, the process proceeds to step S32. If it is a signal other than the unlock signal, the routine is exited.

  In step S32, the door lock actuator 26 provided in the lock mechanism of each door 6L, 6R, 7L, 7R is driven to unlock all the doors 6L, 6R, 7L, 7R, and the process proceeds to step S33. .

  In step S33, it is checked whether or not the unlock signal is being received, that is, whether or not the unlock switch 16U is continuously turned on. When the unlock signal is continuously turned on (so-called long press), The process proceeds to step S34, and when the unlock signal output is interrupted, the routine is exited.

  If it is determined that the unlock signal is continuously output and the process proceeds to step S34, it is checked whether one of the door switches 22 connected to the front doors 6L and 6R has been turned on. When both the door switches 22 connected to the front doors 6L and 6R are in the OFF state, the process returns to step S33. When one of the door switches 22 connected to the front doors 6L and 6R is turned ON, it is determined that the operating conditions are met, and the process proceeds to step S35, and the PSD half-open control subroutine shown in FIG. To exit the routine.

  As described above, in this embodiment, the front door 6R (6L) is opened while the unlock switch 16U of the door remote controller 15 is continuously turned on, and the power slide door 7R (7L) is interlocked with the opening operation. ) Is half-opened, the passenger accidentally operates the door remote controller 15 and the power slide doors 7L and 7R open in conjunction with the opening operation of the front doors 6L and 6R without being aware of it. The probability of being lost can be reduced.

  9 and 10 show a fourth embodiment of the present invention. Here, FIG. 9 is a schematic block diagram of a control device for a vehicle sliding door, and FIG. 10 is a flowchart showing a PSD opening / closing control routine. In addition, about the component same as 1st form, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In each embodiment described above, the half-open operation condition of the power slide doors 7L and 7R is determined based on the combination of the signal from the door remote controller 15 and the opening operation of the front doors 6L and 6R. The combination of the entry system and the opening operation of the front doors 6L and 6R determines the half-open operation conditions of the power slide doors 7L and 7R.

  As shown in FIG. 9, a smart entry receiver 10 that receives a smart entry signal is connected to the input side of the control unit 9 instead of the remote control receiver 9a shown in FIG. The smart entry system is a keyless door entry system that does not require a remote control operation when a passenger gets on, and is between a smart entry transmitter (not shown) such as an electronic card key and the smart entry receiver 10. Thus, ID verification is performed by wireless communication, and the person carrying the smart entry transmitter is recognized as a passenger and enters a standby state.

  The smart entry receiving unit 10 is provided with a handle switch 10a as a smart entry operation switch as selection means. The handle switch 10a is disposed, for example, in the vicinity of the outer handle 19 provided on the front door 6L on the driver's seat. When the passenger carries the smart entry transmitter, the handle switch 10a is turned on. The doors 6L, 6R, 7L, 7R are unlocked.

  The control unit 9 determines the half-open operation condition according to the PSD opening / closing control routine shown in FIG. That is, this routine is started when a passenger carrying a smart entry transmitter comes close. First, in step S41, the handle switch 10a provided on the front door 6R (6L) of the smart entry receiver 10 is activated. It is checked whether or not an ON operation has been performed, or whether or not an ON operation has been performed, and the system waits until the handle switch 10a is turned ON.

  When the passenger turns on the handle switch 10a, the process proceeds to step S42, and the door lock actuator 26 provided in the lock mechanism of each door 6L, 6R, 7L, 7R is driven, and all the doors 6L, 6R, 7L and 7R are unlocked, and the process proceeds to step S43.

  In step S43, the ON operation time Ton of the handle switch 10a is measured. Then, the process proceeds to step S44, where the ON operation time Ton is compared with a preset set time TO (for example, 5 [sec]). When Ton <TO, the process returns to step S41, and the ON operation time Ton of the handle switch 10a is set. measure. When the ON operation time Ton of the handle switch 10a reaches the set time TO, the process proceeds to step S45.

  In step S45, the buzzer 27 is turned on to sound and inform the passenger that the set time TO has been reached.

  Thereafter, the process proceeds to step S46 and waits until the front door 6R (6L) is opened. Then, when the front door 6R (6L) is opened and the door switch 22 is turned on, it is determined that the operation condition is met, and the process proceeds to step S47, and the PSD half-open control subroutine shown in FIG. Exit the routine.

  Thus, in this embodiment, before the front door 6R (6L) is opened, the handle switch 10a is turned ON for a relatively long time, so that the power slide door 7R (7L) is in a standby state in which the half-open operation is possible. Therefore, when the front door 6R (6L) is opened, the power slide door 7R (7L) can be naturally interlocked with the opening.

  Further, when the handle switch 10a is turned off before reaching the set time TO, even if the front door 6R (6L) is opened, the power slide door 7R (7L) does not open halfway. The operation that reflects can be performed and it is easy to use.

  Furthermore, since the smart entry system installed in advance is used as it is, it is not necessary to add a new system, so that this embodiment can be realized without increasing the cost of parts.

  11 and 12 show a fifth embodiment of the present invention. FIG. 11 shows a PSD open / close control routine. In the fourth embodiment described above, the power slide door 7R (7L) is set to a standby state in which the front door 6R (6L) can be opened halfway before opening the front door 6R (6L), but in this embodiment, the front door 6R (6L) is set. ) Is operated to operate the handle switch 10a, it is determined that the half-open operation condition is met, and the power slide door 7R (7L) is operated to be half-open.

  That is, when a passenger carrying a smart entry transmitter approaches, the program is started. First, in step S51, the handle switch 10a provided on the front door 6R (6L) of the smart entry receiver 10 is turned on. It is checked whether or not it has been operated, and waits until the handle switch 10a is turned ON.

  When the passenger turns on the handle switch 10a, the process proceeds to step S52, and the door lock actuator 26 provided in the lock mechanism of each door 6L, 6R, 7L, 7R is driven to drive all the doors 6L, 6R, 7L and 7R are unlocked, and the process proceeds to step S53.

  In step S53, the process waits until the front door 6R (6L) is opened. When the front door 6R (6L) is opened and the door switch 22 is turned on, the process proceeds to step S54, where it is checked whether or not the handle switch 10a is turned on again.

  When the handle switch 10a is turned on again, it is determined that the operating conditions are met, and the process proceeds to step S55, where the PSD half-open control subroutine shown in FIG. 5 is executed, and the routine is exited.

  Thus, in this embodiment, the power slide door 7R (7L) is half-opened by operating the handle switch 10a after opening the front door 6R (6L). If the front door 6R (6L) cannot be opened to the extent that the distance from the adjacent vehicle is narrow when the door 6R (6L) is opened and can be ridden, the handle switch 10a is turned on, The frontage 1d can be expanded to a width that allows the ride. As a result, a smooth ride is possible.

  In this case, the PSD half-open control subroutine shown in FIG. 12 may be executed instead of the PSD half-open control subroutine (see FIG. 5) executed in step S5. In the subroutine shown in FIG. 5, the power slide door 7R (7L) is automatically half-opened to a preset width. However, in the subroutine shown in FIG. 12, the passenger continues the ON operation by the handle switch 10a. During this time, the power slide door 7R (7L) is opened.

  That is, first, after the power slide door 7R (7L) is opened in step S61, the process proceeds to step S62 to check whether the ON operation of the handle switch 10a has been released, and when the ON operation is continued. Returning to step S61, the opening operation of the power slide door 7R (7L) is continued. On the other hand, when the ON operation of the handle switch 10a is released and the switch is in the OFF state, the process proceeds to step S63, and the opening operation of the power slide door 7R (7L) is stopped.

  Then, the process proceeds to step S64, the PSD closing control is executed, and the routine is exited. The PSD closing control executed in step S64 is processed according to the PSD closing control subroutine shown in FIG.

  In the subroutine shown in FIG. 12, when the passenger opens the front door 6R (6L), the steering wheel switch 10a is continuously turned on, thereby requiring an amount (opening width) of the power slide door 7R (7L). ) Can only be operated. Therefore, it is convenient because the passenger can freely set the half-open amount of the front door 1d when boarding.

  By the way, the unlock signal read in step S31 and step S33 of the PSD opening / closing control routine shown in FIG. 8 of the third embodiment described above is replaced with the ON signal output from the handle switch 10a of the smart entry receiver 10. Thus, the PSD opening / closing control routine shown in FIG. 8 can be applied to a vehicle equipped with a smart entry system.

  By applying the PSD opening / closing control routine shown in FIG. 8 to a vehicle equipped with a smart entry system, even when the steering switch 10a is turned on, the power slide doors 7L and 7R can be opened without the operator's knowledge. The probability of the opening operation can be reduced.

  In each embodiment described above, when the power slide door 7R (7L) is opened in conjunction with the opening operation of the front door 6R (6L), the door switch 15 or the handle switch 10a of the smart entry receiver 10 can be easily operated. If operated, an erroneous operation is likely to occur. For this reason, it may be possible to prevent erroneous operations by making it possible to register in advance various switch operations that become triggers based on the intention of the operator (mainly the driver).

  FIG. 13 shows a PSD opening / closing control routine according to the sixth embodiment of the present invention. In addition, since the structure of the whole system is as substantially the same as FIGS. 1-3 of a 1st form, the same code | symbol is attached | subjected about a common component and description is abbreviate | omitted.

  In this embodiment, when the front door 6R (6L) is opened, the touch sensor 21 provided at the tip of the power slide door 7R (7L) is operated in a predetermined manner without adding new switches. The power slide door 7R (7L) is operated only when it is desired to interlock with the opening operation of the passenger's front door 6R (6L).

  That is, in this routine, first, input permission conditions from the touch sensor 21 are determined in steps S71 and S72. In step S71, it is checked whether or not the power slide door 7R (7L) is in a fully closed state based on whether or not the door switch 22 on the power slide door 7R (7L) side is in an OFF state. In step S72, it is checked whether or not the door switch 22 on the front door 6R (6L) side is opened by checking whether or not the door switch 22 on the front door 6R (6L) side is in an ON state.

  When the power slide door 7R (7L) on the power slide door 7R (7L) side is ON, or the door switch 22 on the front door 6R (6L) side is in the OFF state. Exits the routine.

  On the other hand, when the power slide door 7R (7L) with the door switch 22 on the power slide door 7R (7L) side turned off is fully closed, and the door switch 22 on the front door 6R (6L) side is turned on. If yes, go to Step S73.

  In step S73, the touch sensor input permission flag Fse is set (Fse ← 1), and in step S74, the time limit T_over1 (for example, 5 [sec]) that continues to permit pattern input from the touch sensor 21 to the subtraction timer T1. Is set (T1 ← T_over1), and subtraction is started.

  Next, the process proceeds to step S75, and the value of the subtraction timer T1 is referenced to check whether the time is up (T1 = 0). If the time is not up, that is, within the time limit T_over1 (T1 ≧ 0), the process proceeds to step S76. When the time is up, the routine is exited.

  When it is determined that the time is within the time limit T_over1 and the process proceeds to step S76, it is checked whether or not there is a pattern input from the touch sensor 21, and if there is no pattern input, the routine is exited. On the other hand, when there is a pattern input from the touch sensor 21, the process proceeds to step S77, and the input process of the touch sensor 21 is executed.

Here, the input from the touch sensor 21 is performed in accordance with a preset half-open condition. As this half-open condition,
(1) The touch sensor 21 is continuously turned on for a certain time (for example, 3 [sec]) or longer.
(2) Repeat ON / OFF within a certain time (for example, within 3 [sec]) for a certain number of times (for example, 3 times) or more.

Etc. are considered.

  Then, after the input process from the touch sensor 21 is completed in a predetermined manner, the process proceeds to step S78, where a pattern input from the touch sensor 21 is compared with a preset half-open condition. Next, in step S79, the input pattern from the touch sensor 21 is compared with the half-open condition. If the input pattern matches the half-open condition, the process proceeds to step S80, and the input pattern does not match the half-open condition. Exits the routine. Therefore, for example, even when the passenger's elbow or the like is in contact with the touch sensor 21 and the touch sensor 21 is turned on, the input pattern does not match the half-open condition, so the power slide door 7R (7L) There is no malfunction.

  In step S80, the touch sensor input permission flag Fse is cleared (Fse ← 0), the pattern input from the touch sensor 21 is prohibited, and the subtraction timer T1 is cleared in step S81 (T1 ← 0).

  Subsequently, the process proceeds to step S82 where the buzzer 27 is turned on to make a sound and inform the passengers that the power slide door 7R (7L) is half-opened.

  Then, the process proceeds to step S83 to execute the PSD half-open control subroutine shown in FIG. 5 and exit the routine.

  Thus, in this embodiment, when the power slide door 7R (7L) is to be interlocked with the opening operation of the front door 6R (6L), the touch sensor 21 provided at the front end of the power slide door 7R (7L). Since the preset pattern is input from the above, there is no malfunction, and the power slide door 7R (7L) can be half-opened only when necessary. Of course, when the touch sensor 21 is turned ON for a short time, the touch sensor 21 is normally opened in the full opening direction.

  In the first to third embodiments described above, the operation of the power slide doors 7R and 7L is interlocked with the front doors 6R and 6L by operating the lock switch 16L or the unlock switch 16U of the door remote controller 15. However, you may set so that it may interlock | cooperate by operating the other switch provided in the door remote control 15. FIG.

  Moreover, this form is not restricted to each form mentioned above, For example, the opening width of front door 6R (6L) at the time of opening operation | movement in conjunction with power slide door 7R (7L) may be a full open state.
