Description

  The present invention relates to a vehicle door control device that automatically opens and closes a door by door opening and closing means based on a door opening operation and a door closing operation.

  In general, in a one-box type or minivan type vehicle, a vehicle door control device called a so-called auto slide door that automatically opens and closes by sliding a rear side door by a driving force of a door opening / closing means equipped with a motor or the like. Is adopted. In a vehicle equipped with this kind of vehicle door control device, a door opening / closing switch for opening and closing the sliding door is opened and closed to control the door opening / closing means to automatically open and close the sliding door.

  In this type of vehicle door control device, when a so-called squeezing occurs, for example, when an occupant or a baggage is sandwiched by a sliding door that is being closed during the closing operation of the sliding door by the closing control of the door opening / closing means, the sliding door is further increased. In order to stop the closing operation of the door, it is common to immediately stop the closing control of the door opening / closing means, or to perform the pinching avoidance control of the door opening / closing means such as switching the door opening / closing means to the opening control immediately.

  Furthermore, when the pinched state is released, if the sliding door that stops in the middle of the closing operation is left as it is, there is a risk of occupants or luggage being released outside the vehicle. When the sliding door is stopped, it is proposed that the pinch avoidance control is invalidated and the sliding door can be closed based on the operation of some cancel switch (opening / closing restart) by the operator. (See Patent Document 1).

And a parking brake sensor unit 3 for detecting that the parking brake is operated. These vehicle speed sensor unit 1, foot brake sensor unit 2 and parking brake are provided. Based on a signal from the sensor unit 3, a slide door ECU (Electronic Control Unit), which will be described later, detects whether the vehicle is not traveling, that is, in a stopped state or in a traveling state.

  The vehicle speed sensor unit 1 is not limited to a configuration that directly acquires a signal from the vehicle speed sensor, but detects a vehicle speed by receiving a vehicle speed signal from an ABS (Antilock Brake System) ECU (not shown) through CAN (Controller Area Network) communication. It may be a thing.

  In addition, as shown in FIG. 1, a door sensor 4 for detecting the moving speed of the sliding door is provided to detect whether the sliding door at the rear of the host vehicle is opened and closed at a predetermined speed, and the sliding door is caught. The slide door includes a latch switch 5 for detecting latch (lock). Based on signals from the door sensor 4 and the latch switch 5, a slide door ECU (to be described later) inserts an occupant or luggage into the slide door. It is detected whether the opening or closing operation of the sliding door has stopped midway due to a malfunction of the opening / closing control signal of the sliding door. The door sensor 4 and the latch switch 5, and the sliding door ECU that detects a stop in the middle of the opening and closing operations of the sliding door based on signals from these correspond to the detecting means in the present invention.

  Further, as shown in FIG. 1, a door opening / closing switch 6 for opening and closing the sliding door is provided. The door opening / closing switch 6 is provided on an outer handle and an inner handle of the sliding door and is operated from outside and inside the vehicle. A steering wheel switch 6a, an instrument panel opening / closing switch 6b that is provided on an instrument panel at a position other than the sliding door and is operated mainly by a driver, and a remote controller for a driver in a so-called key-free system. The remote control opening / closing switch 6c is generically named. If there is a door opening operation and a door closing operation of any one of the handle switch 6a, the instrument panel opening / closing switch 6b, and the remote control opening / closing switch 6c, an opening operation signal and a closing operation signal by the operation of these switches 6a, 6b, 6c will be described later. Is input to the sliding door ECU. Here, the opening / closing operation signal from the remote control opening / closing switch 6c is a wireless signal, and when the sliding door ECU 11 receives this wireless opening / closing operation signal, the opening / closing control and closing control of the door opening / closing means described later are performed. Is done.

  Further, as shown in FIG. 1, a slide door opening / closing motor and a driving mechanism for opening / closing the rear sliding door by the driving force of the motor are provided, and the rear sliding door is automatically operated by the driving force of the door opening / closing means. A door opening / closing means 7 for opening and closing is provided, and when the sliding door is in a half-door state, or when the sliding door ECU detects a stop during the opening / closing operation of the sliding door based on signals from the door sensor 4 and the latch switch 5. A buzzer drive unit 9 is provided for driving a buzzer for notifying the driver and passengers of an abnormality. The buzzer drive unit 9 is also controlled during normal closing control of the sliding door.

  Further, as shown in FIG. 1, a slide door ECU 11 which is a control means in the present invention is provided, and by the slide door ECU 11, signals from the sensor units 1 to 3 and 7 and the switches 4 to 6 are received. Based on this, the door opening / closing means 7 performs opening control for opening the sliding door and closing control for closing the sliding door, and the buzzer driving unit 9 is controlled.

  The detected vehicle speed by the vehicle speed sensor unit 1 is zero, and the foot brake sensor unit 2 detects that the foot brake is stepped on while the shift lever of the vehicle is in the P (parking) range. 3, when it is detected that the parking brake is operated, the sliding door ECU 11 detects the stop state of the host vehicle, while the vehicle speed detected by the vehicle speed sensor unit 1 is not zero or the brake sensor unit 2 When it is detected that the shift lever of the vehicle is outside the P (parking) range or the foot brake is not depressed, or the parking brake sensor unit 3 detects that the parking brake is not operated, the slide The traveling state of the host vehicle is detected by the door ECU 11.

  When the sliding door is fully open and the sliding door ECU 11 detects that the vehicle is in a stopped state, and there is an input of a closing operation signal based on the door closing operation from the door opening / closing switch 6, the sliding door The normal closing control of the door opening / closing means 7 by the door ECU 11 is performed, and the fully opened slide door is driven in the closing direction. When the sliding door moves to the fully closed position, the closing control of the door opening / closing means 7 is stopped. At this time, the buzzer drive unit 9 is controlled by the slide door ECU 11, and a buzzer sound for notifying that the sliding door is being closed is sounded in a predetermined pattern or tone to alert the user to prevent pinching. To do.

  Further, when the sliding door is in a fully closed state and the sliding door ECU 11 detects that the own vehicle is in a stopped state, and there is an input of an opening operation signal based on the door opening operation described above from the door opening / closing switch 6, Open control of the door opening / closing means 7 is performed by the slide door ECU 11, and the fully closed slide door is driven in the opening direction. When the sliding door moves to the fully open position, the opening control of the door opening / closing means 7 is stopped.

  As shown in FIG. 2, when a closing operation signal based on the closing operation of any one of the switches 6 a, 6 b, 6 c of the door opening / closing switch 6 is input to the sliding door ECU 11, the door opening / closing means 7 is moved by the sliding door ECU 11. The sliding door SD of the own vehicle M is automatically driven in the closing direction indicated by the arrow in the drawing, and is called the sliding door SD and the B pillar during the closing operation of the sliding door SD. The closing operation of the sliding door SD is stopped halfway due to the object OB such as an occupant or baggage being caught between the center pillar P1 or the rear pillar P2 called C-pillar and the control signal for closing control. Then, based on the signals from the door sensor 4 and the door latch switch 5, the sliding door ECU 11 stops the slide SD in the middle. There is detected, closing control of the door opening and closing means 7 to close the sliding door is stopped immediately. Further, even when an opening operation stop for some reason is detected during the opening operation by the opening control of the slide door SD, the opening control of the door opening / closing means 7 for opening the sliding door is immediately stopped as described above. The process in which the opening control and the closing control by the sliding door ECU 11 are immediately stopped after the sliding door SD is closed during the closing and opening operations corresponds to the stopping means in the present invention.

  Then, the sliding door ECU 11 detects that the sliding door SD is in a half door state where the sliding door SD is not closed, and detects the pinching by signals from the door sensor 4 and the latch switch 5, so that the sliding door ECU 11 detects the buzzer drive unit. 9 is controlled, and a buzzer sound of a pattern and a tone color notifying that the sliding door SD has stopped midway is sounded. Further, even when the sliding door SD is stopped during the opening operation, a pattern or tone buzzer sounding that the sliding door SD has stopped midway is sounded. Note that the buzzer sound in this case is preferably different in pattern and tone color from the buzzer sound informing the half-door state, but may be the same.

  At this time, if the cause of the stop is canceled after the closing or opening operation of the slide door SD is stopped halfway, the closing control by the door closing operation of any of the switches 6a, 6b, 6c of the door opening / closing switch 6 is performed. However, when the driver goes out of the vehicle and operates the remote control opening / closing switch 6c to close the door, it is not always possible to insert the slide door SD. The door closing operation is not always performed after visually confirming that the cause of the stop of the sliding door SD has been released.

  Based on such a situation, as a characteristic configuration of the present embodiment, after the operation of the sliding door SD stops halfway and the opening and closing control of the door opening / closing means 7 by the sliding ECU 11 is stopped, the sliding door SD Even if the door ECU 11 receives the opening operation signal and the closing operation signal for the door opening operation and the door closing operation by the remote control opening / closing switch 6c, the door opening operation and the door closing operation by the remote control opening / closing switch 6c are invalidated (not permitted). Then, the door opening operation and the door closing operation of the handle switch 6a and the instrument panel opening / closing switch 6b other than the remote control opening / closing switch 6c are validated (permitted) as usual.

  As described above, the operation of the remote control opening / closing switch 6c is invalidated, and the opening operation and the closing operation of the handle switch 6a and the instrument panel opening / closing switch 6b are validated. Also, based on the instrument panel opening / closing switch 6b close to the slide door SD (including automatic stop due to an abnormality during the closing operation and stop due to the opening / closing operation), and the door opening / closing operation of the handle switch 6a closest to the sliding door SD. Thus, it is possible to execute the opening control and the closing control by the door opening / closing means 7 after visually confirming that it is safe to remove the cause of the sliding door SD being stopped in the middle, such as pinching.

  Next, the operation of the sliding door ECU 11 will be described with reference to the flowchart of FIG.

  As shown in FIG. 3, based on a signal from any one of the switches 6a, 6b, 6c of the door opening / closing switch 6, the slide door ECU 11 determines whether there is a door opening operation or a door closing operation ( Step S1) If the determination result is NO, the determination of step S1 is repeated until the determination result is YES. If the decision result in the step S1 is YES, the sliding door ECU 11 controls the door opening / closing means 7 based on the door opening operation or the door closing operation in the step S1, and the opening control or closing control of the sliding door SD is started. (Step S2). At this time, the buzzer driving unit 9 is controlled by the slide door ECU 11, and a buzzer sound is generated with a predetermined pattern or tone color to notify that at least the closing control of the slide door SD is being executed.

  Subsequently, based on signals from the door sensor 4 and the door latch switch 5, it is determined by the slide door ECU 11 whether or not an operation stop in the middle of the slide door SD due to pinching or the like has been detected (step S3). If the determination result is NO (no detection), the process proceeds to step S8 to be described later. If the determination result is YES (detection), the sliding door ECU 11 serving as a stop unit opens and closes the door opening / closing means 7. (Step S4), the opening and closing operations of the slide door SD are immediately stopped, and the operation of the remote control opening / closing switch 6c of the door opening / closing switch 6 is invalidated (not permitted) by the sliding door ECU 11, while the handle The operation of the switch 6a and the instrument panel opening / closing switch 6b is validated (permitted) (step S5).

  Subsequently, in step S6, it is determined whether or not there is a door closing operation of the handle switch 6a or the instrument panel opening / closing switch 6b (step S6). If the determination result is YES, the handle switch 6a or the instrument panel opening / closing switch 6b is determined. The closing operation signal by the door closing operation is input to the slide door ECU 11, the closing operation signal is determined to be valid by the sliding door ECU 11, and the closing control of the sliding door SD by the door opening / closing means 7 is resumed (step S7). Based on the signal from the latch switch 5, the slide door ECU 11 determines whether or not the slide door SD is fully closed (step S8). If the determination result is NO, the determination in step S8 is performed until the determination result is YES. Is repeated, the sliding door SD is fully closed, and step S The result of the determination operation if to YES to end.

  On the other hand, if the determination result in step S6 is NO, that is, if it is determined that the handle switch 6a and the instrument panel opening / closing switch 6b are not closed, the process proceeds to step S9, where the handle switch 6a or the instrument panel opening / closing switch 6b is operated. It is determined whether or not there is a door opening operation (step S9). If the determination result is YES, an opening operation signal by the door opening operation of the handle switch 6a or the instrument panel opening / closing switch 6b is input to the slide door ECU 11. The opening operation signal is determined to be valid by the sliding door ECU 11, and opening control of the sliding door SD by the door opening / closing means 7 is started (step S10).

  Then, after the opening control of the sliding door SD by the door opening / closing means 7 is started, the sliding door ECU 11 determines whether or not the sliding door SD is fully opened (step S11). If the determination result is NO, the determination result is NO. The determination in step S11 is repeated until “YES” is reached, and if the sliding door SD is fully opened and the determination result in step S8 is “YES”, the operation ends.

  When the closing control of the sliding door SD in step S7 is resumed, the sliding door ECU 11 controls the buzzer driving unit 9, and the buzzer sound at the time of the normal closing control in step S2 is different or different. A buzzer sound of a pattern or tone may be played.

  Therefore, according to the above-described embodiment, based on the signals from the door sensor 4 and the latch switch 5, the sliding door ECU 11 detects a stop in the middle of the opening and closing operations of the sliding door SD for some reason such as pinching, When the sliding door ECU 11 stops the opening and closing operations of the sliding door SD, after the stopping, the door opening operation by the remote control opening / closing switch 6c that can be operated from a place away from the sliding door SD where pinching or the like occurs is performed. The door closing operation is disabled, and the door opening / closing control by the door opening / closing means 7 based on the door opening / closing operation by the handle switch 6a or the instrument panel opening / closing switch 6b provided on the body of the host vehicle M can be executed. Become.

  As a result, the operation of the remote control opening / closing switch 6c that can be operated from a place away from the host vehicle M is invalidated, and the operation of the instrument panel opening / closing switch 6b close to the driver's seat and the handle switch 6a provided on the slide door SD are validated. Therefore, based on the door closing operation of the handle switch 6a and the instrument panel opening / closing switch 6b provided on the vehicle body, it is possible that the abnormality such as pinching has been canceled or there is no danger of pinching or the like in the vicinity of the sliding door SD. The opening / closing control of the door opening / closing means 7 can be executed after being confirmed by visual observation of the driver or driver of the driver's seat, and sufficient safety can be ensured.

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the case where only the operation of the remote control opening / closing switch 6c is invalidated (not permitted) has been described. However, in addition to the remote control opening / closing switch 6c, the operation of the instrument panel opening / closing switch 6b is also invalidated. Only the door closing operation and the door opening operation may be validated (permitted). In this case, since the handle switch 6a is located closest to the sliding door where the pinching occurs, only the switch operation at a position where it is easy to visually confirm the release of the cause of the sliding door SD stopping due to the pinching is effective. As a result, further safety can be ensured.

  Further, the sliding door SD stops operating halfway, and after the opening / closing control of the door opening / closing means 7 is stopped by the sliding door ECU 11 as the stopping means, only one of the door closing operation or the door opening operation is validated. You may do it.

  In the above-described embodiment, the case where the opening and closing operations of the slide door SD are immediately stopped after the operation of the slide door SD is stopped is described. The means 7 may be switched to open control.

  In the above-described embodiment, the slide door is described as an object. However, the present invention can be applied to a hinged door, and the target door is not limited to the rear part of the vehicle.
