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 order to ensure safety, this type of vehicle door control device prohibits automatic opening and closing of the sliding door while traveling, and enables the control of automatic opening and closing of the sliding door only when the vehicle is stopped. It is common.

  At this time, whether the vehicle is stopped is determined by whether the vehicle speed detected by the vehicle speed detection means such as a vehicle speed sensor is equal to or lower than a predetermined vehicle speed (for example, 3 km / h), and either the foot brake or the parking brake It is considered to determine whether or not the vehicle is in a stopped state on the condition that is operated (see Patent Document 1).

Japanese Utility Model Publication No. 5-74941 (see paragraphs 0008 to 0009 and FIG. 3)

  By the way, the vehicle speed detection means such as the vehicle speed sensor itself fails or the detection signal output from the vehicle speed detection means becomes an erroneous signal due to noise or some other influence, and the vehicle is originally stopped and detected by the vehicle detection means. The car speed that is supposed to be zero may not be zero.

  In such a case, in the above-described one disclosed in Patent Document 1, it is determined that the detected vehicle speed is not zero and the vehicle is in a running state even though the vehicle is really stopped, and the sliding door is automatically operated. The sliding door cannot be opened from outside the vehicle due to the inability to control the opening and closing, and even if the vehicle is stopped, the occupant is trapped without being able to get out of the vehicle from the sliding door, or the slide is open. The inconvenience arises that the door cannot be closed.

  The present invention is provided outside the passenger compartment when the detected vehicle speed of the vehicle that is actually stopped is not zero due to a failure of the vehicle speed detection means or some influence, or when the vehicle speed signal is abnormal even if the detected vehicle speed is zero. Another object of the present invention is to enable the open / close control of the door opening / closing means to be executed by effectively receiving an open / close operation signal of the vehicle outside switch.

In order to achieve the above-described object, a vehicle door control device according to the present invention includes an open / close operation signal by an operation of a vehicle interior switch provided in a vehicle interior of the vehicle, and a vehicle exterior switch provided outside the vehicle interior. In the vehicle door control device that automatically opens and closes the door by the door opening and closing means based on the opening and closing operation signal by the operation of the vehicle, the vehicle speed detection means for detecting the vehicle speed of the vehicle and outputting the detection signal, and the brake operation status or the shift lever position is a stop state detecting means for detecting whether status indicating the stop state of the vehicle, the door opening and closing means based on the opening operation signal and the closing operation signal by the operation of the vehicle interior switches and the vehicle exterior switch the a controlled open and control means for closing control, the control means, the vehicle is detected to be in the situation shown in the stopped state by said stopping state detection means When the, or the detected vehicle speed by the vehicle speed detecting means is equal to or higher than a predetermined vehicle speed, or the if there is an abnormality in the detection signal of the vehicle speed detecting means, the opening from the vehicle exterior switch, to enable the closing operation signal The door opening / closing means can be controlled to be executed upon receipt (claim 1).

According to the first aspect of the invention, the vehicle speed detecting means such as the vehicle speed sensor itself fails or the detection signal output from the vehicle speed detecting means becomes an erroneous signal due to noise or some other cause, and the stop condition detecting means When it is detected that the brake operation status or the shift lever position indicates a vehicle stop state, the detected vehicle speed is not zero or the vehicle speed is There may be a case in which there is an abnormality in the vehicle speed detection that the vehicle speed signal is zero but there is an abnormality in the vehicle speed signal. In order to cope with such an abnormality, when it is detected that the vehicle is in a stopped state, the control means accepts an open / close operation signal of the vehicle outside switch effectively and opens the door opening / closing means. Then, the closing control is executed.

  As a result, if for some reason the detected vehicle speed of a vehicle that should have stopped is abnormal, such as when the detected vehicle speed is not zero, the door switch on the outside of the passenger compartment is operated to open or close the door. Based on the opening operation signal or the closing operation signal by the opening operation or the door closing operation, the opening / closing control of the door opening / closing means by the control means is executed, so that the door can be opened or closed from the outside of the vehicle. It is possible to prevent the occurrence of confinement and the situation where the door cannot be closed. Here, the door may be either a sliding type or a hinge type.

It is a block diagram of one embodiment of a vehicle door control device according to the present invention. It is a flowchart for operation | movement description of FIG.

  Next, in order to describe the present invention in more detail, an embodiment of the present invention will be described in detail with reference to the block diagram in FIG. 1 and the flowchart for explaining operations in FIG.

  As shown in FIG. 1, the vehicle door control device according to the present embodiment is in a state where the vehicle speed sensor unit 1 as vehicle speed detection means for detecting the vehicle speed of the host vehicle and the shift lever of the host vehicle are in the P (parking) range. And a parking brake sensor unit 3 for detecting that the parking brake is operated. These vehicle speed sensor unit 1 and foot brake sensor are provided. Based on signals from the unit 2 and the parking brake 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. Is done.

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

  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 door latch switch 5 that detects latch (lock). Based on signals from the door sensor 4 and the door latch switch 5, a slide door ECU (to be described later) It is detected whether or not an abnormality has occurred that the closing operation of the sliding door stops halfway due to a malfunction of the opening / closing control signal of the sliding door.

  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. The outer handle switch 6a and the inner handle switch 6b, the instrument panel opening / closing switch 6c provided on the instrument panel at a position other than the sliding door and operated mainly by the driver, and a remote controller for the driver in a so-called key-free system. The remote control opening / closing switch 6d provided is a general term. If there is a door opening operation and a door closing operation of any one of these switches 6a, 6b, 6c, 6d, an opening operation signal and a closing operation signal by the operation of the switches 6a, 6b, 6c, 6d will be described later. It is input to the ECU.

  Here, the inner handle switch 6b and the instrument panel opening / closing switch 6c correspond to the vehicle interior switch provided in the vehicle interior in the present invention. The outer handle switch 6a and the remote control open / close switch 6d when the area is recognized as being outside the vehicle are provided. The remote control opening / closing switch 6d, which corresponds to the vehicle exterior switch provided outside the vehicle compartment in the present invention and is recognized as being in the vehicle, does not correspond to the vehicle exterior switch in the present invention. Note that the open / close operation signal from the remote control opening / closing switch 6d is a radio signal, and when the slide door ECU 11 receives this radio open / close operation signal, the door open / close means, which will be described later, are controlled to open and close. Is called.

  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 opened / closed by the driving force of the motor. The door opening / closing means 7 is provided, and when the sliding door is in a half-door state or when an abnormality of the sliding door such as pinching by the sliding door ECU based on signals from the door sensor 4 and the door latch switch 5 is detected, A buzzer drive unit 9 for driving a buzzer for notifying an occupant of an abnormality is provided. Even during normal closing control of the sliding door, the buzzer driving unit 9 is controlled for alerting.

  Further, as shown in FIG. 1, a slide door ECU 11 which is a control means in the present invention is provided, and signals from the sensor units 1 to 3, the door sensor 4, and the switches 5 and 6 are provided by the slide door ECU 11. Based on the above, opening control for opening and closing the sliding door by the door opening / closing means 7 and closing control for closing the sliding door are executed, and the buzzer driving unit 9 is controlled.

  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, and the parking brake sensor unit 3 is operating the parking brake. When detected, the sliding door ECU 11 detects that the operation state of the brake (foot brake, parking brake) and the shift lever position are in a state (P range) indicating the stop state of the host vehicle, while the brake sensor unit When it is detected by 2 that the shift lever of the host vehicle is outside the P range or the foot brake is not depressed, and the parking brake sensor unit 3 detects that the parking brake is not operated, the slide door ECU 11 Brake (foot brake, parking brake) It is detected that the operation state of the rake) and the shift lever position are not in a state indicating the stop state of the own vehicle. As described above, the process of detecting whether or not the brake operation state or the shift lever position indicates the stop state of the host vehicle by the slide door ECU 11 corresponds to the stop state detection means in the present invention.

  When the sliding door ECU 11 detects that the vehicle speed detected by the vehicle speed sensor unit 1 is zero and the brake operation state and the shift lever position indicate a stop state of the host vehicle, the host vehicle stops. Determined to be in a state. On the other hand, when the sliding door ECU 11 detects that the vehicle speed detected by the vehicle speed sensor unit 1 is not zero and the brake operation state and the shift lever position are not in a state indicating the stop state of the host vehicle, the host vehicle is in a running state. It is judged that

  Thus, when it is determined that the host vehicle is in a stopped state, if the sliding door is in a fully open state and a closing operation signal based on the door closing operation is input from the door opening / closing switch 6, the sliding door Normal closing control of the door opening / closing means 7 by the ECU 11 is performed, and the fully opened sliding 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.

  When it is determined that the vehicle is in a stopped state, if the sliding door is in a fully closed state and an opening operation signal is input from the door opening / closing switch 6 based on the door opening operation, the sliding door The opening control of the door opening / closing means 7 by the ECU 11 is performed, and the fully closed sliding 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.

  Further, when it is determined that the host vehicle is in the traveling state, the opening operation signal based on the door opening operation from the door opening / closing switch 6 is not allowed for safety, and in the traveling state, these opening operation signals by the slide door ECU 11 are not allowed. The opening control based on is not executed. In other words, a closing operation signal based on a door closing operation is permitted from a state in which the slide door is open.

  However, the sensor itself of the vehicle speed sensor unit 1 breaks down, or the detection signal output from the vehicle speed sensor unit 1 becomes an erroneous signal due to noise or some other cause, and the sliding door ECU 11 controls the brake operation status and the shift lever position. Is detected to indicate that the vehicle is stopped, the detected vehicle speed is not zero even though the vehicle is really stopped, or the vehicle speed signal is abnormal even if the vehicle speed is zero. It is conceivable that a vehicle speed detection abnormality such as

  In order to be able to cope with such an abnormality in the vehicle speed detection, as described above, the slide door ECU 11 determines the brake operation status and the shift lever based on the signals from the foot brake sensor unit 2 and the parking brake sensor unit 3. If it is detected that the position is in a state indicating the stop state of the host vehicle, if the vehicle speed detected by the vehicle speed sensor unit 1 is greater than a predetermined vehicle speed such as 3 km / h or an abnormality in the vehicle speed signal is detected, An outer handle switch 6a that is an outside switch of the vehicle and a remote control opening / closing switch that is recognized as being outside the vehicle, not accepting an opening operation signal based on the door opening operation of the inside switch Only the opening operation signal based on the 6d door opening operation is allowed, and the opening control of the door opening / closing means 7 is executed. You have me. In addition, although the above-mentioned predetermined vehicle speed was 3 km / h in consideration of the allowable error range of meter display, it is not necessary to specifically limit to this.

  During the closing control by the slide door ECU 11 when the vehicle speed detection is abnormal, the buzzer drive unit 9 is controlled by the slide door ECU 11, and the pattern and tone are different from those during the normal closing control of the sliding door SD and when the half door is notified. A buzzer sound is sounded to notify the driver and passengers that the vehicle speed detection is being dealt with abnormally. In addition, it is desirable that the opening speed of the sliding door when the vehicle speed detection is abnormal is slower than the normal opening operation. In this way, the vehicle speed detection abnormality is being dealt with by making the opening speed slower than normal. It can be easily recognized by the driver and passengers.

  Next, the opening control operation when the above-described sliding door ECU 11 detects an abnormal vehicle speed will be described with reference to the flowchart of FIG.

  As shown in FIG. 2, the slide door ECU 11 determines whether or not the slide door is fully closed or closed so that the passenger cannot get off (half-open state) (step S1). If the determination result in step S1 is YES, the positions of the foot brake, the parking brake, and the shift lever indicate that the vehicle is stopped based on the signals from the brake sensor unit 2 and the parking brake sensor unit 3. It is determined whether or not the situation is shown (step S2).

  If the determination result in step S2 is NO, the operation ends as it is. If the determination result in step S2 is YES, whether or not the vehicle speed detected by the vehicle speed sensor unit 1 is equal to or higher than a predetermined vehicle speed (for example, 3 km / h). A determination is made (step S3). If the determination result is NO, it is determined that the host vehicle is really stopped and the operation is terminated. If the determination result is YES, it is determined that the vehicle speed detection is abnormal. Next step S4 is entered.

  In step S4, the door opening operation of the outer handle switch 6a which is an outside switch of the door opening / closing switch 6 or the remote control opening / closing switch 6d recognized as being outside the vehicle is permitted (step S4). It is determined whether there is a 6d door opening operation (step S5). If the determination result is NO, the determination in step S5 is repeated until the determination result is YES.

  If the determination result in the step S5 is YES, the door by the sliding door ECU 11 is based on the opening operation signal by the door opening operation of the vehicle exterior switch (the outer handle switch 6a or the remote control opening / closing switch 6d recognized as being outside the vehicle). The opening control of the opening / closing means 7 is started (step S6), and then, based on signals from the door sensor 4 and the door latch switch 5 or the like, it is determined whether or not the sliding door is fully opened (step S7). If the result is NO, the determination in step S7 is repeated until the determination result is YES. If the sliding door is fully opened and the determination result in step S7 is YES, the operation ends.

  As described above, the sensor itself of the vehicle speed sensor unit 1 breaks down, or the detection signal output from the vehicle speed sensor unit 1 becomes an erroneous signal due to noise or some other cause, and the slide door ECU 11 causes the foot brake and the parking brake to Vehicle speed detection abnormality that the detected vehicle speed is not zero when it is detected that the operation status or shift lever position indicates the stop state of the host vehicle, even though the host vehicle is actually stopped In order to cope with this vehicle speed detection abnormality, the sliding door ECU 11 opens the vehicle outside switch (the outer handle switch 6a or the remote control opening / closing switch 6d recognized as being outside the vehicle). The signal is effectively accepted and the opening control of the door opening / closing means 7 is executed.

  As described above, according to the above-described embodiment, when an abnormality occurs in the vehicle speed that the detected vehicle speed of the vehicle that should have stopped is not zero due to some cause, the outer handle switch 6a that is the vehicle outside switch or the vehicle outside the vehicle. When the remote control opening / closing switch 6d whose area has been recognized is opened, the sliding door ECU 11 performs the opening control of the door opening / closing means 7 based on the opening operation signal of the door opening operation, so the sliding door is opened from the outside of the vehicle. Thus, unlike the prior art, it is possible to prevent a situation in which the occupant is trapped in the vehicle without being able to open the slide door even though the vehicle is actually stopped.

  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 the opening operation of the outer handle switch 6a that is a vehicle exterior switch and the remote control opening / closing switch 6d that is recognized as being outside the vehicle by the slide door ECU 11 when the vehicle speed abnormality is detected has been described. However, the opening operation of only one of the outer handle switch 6a or the remote control opening / closing switch 6d recognized as being outside the vehicle may be permitted.

  Further, in the above-described embodiment, the case where the opening operation of the outer handle switch 6a that is the vehicle exterior switch or the remote control opening / closing switch 6d that is recognized as being outside the vehicle by the slide door ECU 11 when the vehicle speed abnormality is detected has been described. However, the door closing operation of the vehicle exterior switch (the outer handle switch 6a and the remote control opening / closing switch 6d recognized as being outside the vehicle) may be permitted.

  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.

  In the embodiment described above, it is determined whether or not “the detection signal is equal to or higher than the predetermined speed” in step S3. Instead, it is determined whether or not “the vehicle speed signal is abnormal”. It may be.
