Abstract

PROBLEM TO BE SOLVED: To provide an open/close body control system capable of reliably opening/closing of an open/close body while preventing a sharp speed change of a vehicle open/close body.SOLUTION: A sunroof device 1 has a roof panel 3 for opening/closing an opening 4 by a switch operation. The roof panel 3 carries out SW soft start/stop in which the speed is gradually increased/decreased when a switch is turned ON/OFF, and PO soft stop in which the speed is gradually decreased in a stop control area SC of a full close/open position. When the switch is turned OFF, in the vicinity of stop control area SC while a panel moves, the PO soft stop is carried out without carrying out the SW soft stop (shift control (a)). When reaching the stop control area SC while the soft start is carried out, the sunroof device shifts from the soft start control to the PO soft stop (shift control (b)). When the switch is turned ON while the panel is positioned in a stop control area SC, the PO soft stop is carried out without carrying out the soft start control (shift control (c)).SELECTED DRAWING: Figure 2

Description

  The present invention relates to a control system for a vehicle opening / closing body such as a sunroof, and more particularly to a technique effective when applied to an opening / closing body control system having an automatic stop position where the operation automatically stops, such as a fully open / fully closed position.

  Conventionally, in a vehicle opening / closing body such as an electric sunroof, an automatic sliding door, and a power window, the opening / closing body operation is started / stopped by a user's switch operation. On the other hand, when the sunroof or the like is opened / closed, an automatic stop position (for example, a fully open / fully closed position) is provided, and a control form is also adopted in which the open / close body is stopped at a desired position.

  For example, Patent Document 1 describes a control form that accurately positions the fully closed position of the sunroof. In this case, when the sunroof reaches a predetermined region near the fully closed position, the displacement amount of the sunroof after that is measured. When the value reaches a predetermined value, the motor operation is stopped. Patent Document 2 describes a device that compares the current position of a moving body (window glass) with a target position, and controls the motor so that the speed decreases as the moving body approaches the target position. As a result, the moving body is accurately stopped at the target position, and the feeling at the time of stopping is improved.

  Further, in recent years, vehicles that employ so-called soft start / soft stop, in which the speed of the opening / closing body is gradually increased or decreased in order to improve the operational feeling at the time of start / stop, are increasing. FIG. 4 is an explanatory diagram showing changes in the motor rotational speed when soft start / soft stop is employed in the electric sunroof. In this case, there are two control modes for soft start / soft stop: a control operation by a switch operation (FIG. 4A) and a control operation by a position of a sunroof (opening / closing body) (FIG. 4B). . Note that the horizontal axis of FIG. 4B indicates the passage of time at the time of startup and the distance from the automatic stop position at the time of stop.

  First, in the soft start / soft stop by the switch operation, as shown in FIG. 4A, the rotational speed of the motor is gradually increased from the soft start start rotational speed N1 from the start to the steady state target rotational speed Nt. (Time T1: about 2 seconds, for example). As a result, the sunroof does not start abruptly and reaches a steady state speed while gradually increasing the speed. On the other hand, after the target rotational speed Nt is reached after time T1, when the switch is turned OFF, this time is multiplied by time T2 (for example, about 2 seconds), and the motor rotational speed is gradually reduced to the soft stop end rotational speed N2. Go and then stop the sunroof due to inertia. Thus, after the switch is turned off, the sunroof does not stop suddenly, but gradually decreases in speed and eventually stops in a natural manner.

  The soft stop by position is the same as that in FIG. 4A at the time of start-up, but here, when the sunroof comes near the stop position such as the fully open position or the fully closed position, as shown in FIG. In addition, the motor speed is gradually reduced. That is, when the sunroof reaches the stop control region SC set at a predetermined distance P3 (detected by the motor pal count value: for example, about 10 mm) from the automatic stop position, the soft stop mode is set. Then, the motor rotation speed is controlled so that the motor reaches the soft stop end rotation speed N3 at a distance P4 (for example, about 3 mm) from the automatic stop position. When the sunroof comes to the position of the distance P4, the motor drive control ends there, and then the sunroof moves due to inertia and stops at the automatic stop position. As a result, the sunroof does not stop suddenly at the stop position, but gradually decreases in speed and stops at the automatic stop position in a natural manner.

  However, as described above, since the operation of the opening / closing body is also performed by the user's switch operation, if the user performs the switch operation in the vicinity of the automatic stop position or the target position, both compete and the opening / closing body becomes the user's operation. There is a possibility of unintended operation. For example, in the electric sunroof device performing soft start / soft stop control as shown in FIG. 4, when the user performs a switch operation near the fully closed position, the sunroof does not completely close or the motor rotation speed during operation There is a problem that the motor sound may fluctuate due to changes in the motor.

  For example, in the apparatus in which the control shown in FIG. 4 is performed, when the user operates the close switch ON (operates the sunroof opening / closing switch in the closing direction) and the sunroof roof panel is in the closing operation, After the switch is turned off, the sunroof device performs a soft stop operation by operating the switch. Then, the stop operation control as shown in FIG. 4A is performed. At this time, since the switch is already in the OFF state, the soft stop by the position is executed even when approaching the fully closed position (the automatic stop position in this case). Not. That is, regardless of the distance from the fully closed position, the motor stops at time T2. As a result, the motor stops before the roof panel is completely closed, and the roof panel may not reach the fully closed position after the switch is turned off. At this time, if the opening amount (remaining closing amount) of the roof panel is small, there is a possibility that the user does not notice it and misunderstands that the sunroof is fully closed.

  In addition, when the user turns on the close switch while the roof panel is stopped at a position close to full close, the roof panel starts the close operation while performing the soft start operation. However, since the roof panel immediately reaches the vicinity of the fully closed position, after that, a soft stop operation according to the position is performed. At that time, the soft stop by the switch operation and the soft stop by the position may have different motor rotation speeds at the time of the soft stop control, so that there may be a speed fluctuation different from the normal operation. That is, there is a possibility that the motor is controlled in such a way as to move from the point Q1 to the point Q2 in FIG. 4A, the motor rotation speed fluctuates abruptly, an unstable movement or abnormal noise occurs, and the user May be uncomfortable.

  Further, when the close switch is turned on when the sunroof is stopped in the vicinity of the fully closed position (within the soft stop region depending on the position), the same competition phenomenon as described above may occur. That is, there is a possibility that the soft start by the switch operation and the soft stop by the position compete with each other, and the motor rotation speed may fluctuate in an unstable manner.

  An object of the present invention is to provide an open / close body control system and an open / close body open / close operation control method capable of preventing a sudden speed fluctuation of the open / close body for a vehicle and reliably opening and closing the open / close body.

  An opening / closing body control system according to the present invention is disposed at an opening of a vehicle and opens / closes the opening, a motor for operating the opening / closing body, and controls the motor to open / close the opening. And an opening / closing body control system for performing an opening / closing operation of the opening / closing body by a user's switch ON / OFF operation, wherein the control means, after the switch OFF operation, A first stop execution unit that performs a first stop control to gradually reduce the speed of the opening / closing body over time and stop the opening / closing body; and the opening / closing body from a predetermined stop position during the switch ON operation Second stop control for gradually reducing the speed of the opening / closing body based on the distance from the stop position to stop the opening / closing body at the stop position when reaching the predetermined stop control region A second stop execution unit to perform, and a control mode selection unit to select and implement only one of the first stop control and the second soft stop control based on the position of the opening / closing body. Features.

  In the present invention, the control mode selection unit selects and executes only one of the first stop control and the second soft stop control based on the position of the opening / closing body. Therefore, even if the first stop control and the second soft stop control compete, either one is implemented, and the opening / closing body can move to a predetermined stop position due to the competition between the two. The phenomenon that the motor rotation speed fluctuates and abnormal noise occurs during the movement of the opening / closing body is suppressed.

  In the opening / closing body control system, the control mode selection unit moves the opening / closing body to a position within a predetermined range from the stop control area while the opening / closing body moves relative to the stop position in accordance with the switch ON operation. When the switch OFF operation is performed when it exists, the second soft stop control may be performed without performing the first stop control. Thereby, even if the switch is turned off before the stop control region near the stop position, the second soft stop control is performed, and the opening / closing body can be reliably moved to the stop position.

  The control means further includes a soft start execution unit for performing a soft start control for gradually increasing the speed of the opening and closing body with the lapse of time after the switch is turned on, and the control mode selection unit includes the control mode selection unit, When the opening / closing body exists outside the stop control area, the switch ON operation is performed, and when the opening / closing body reaches the stop control area during the execution of the soft start control, the soft start control to the second software You may make it transfer to stop control. Thereby, the competition between the soft start control and the second soft stop control can be avoided. In this case, the transition to the second soft stop control may be performed while maintaining the rotation speed of the motor at the time of the soft start control, whereby the second soft stop control is performed from the soft start control. It is possible to suppress fluctuations in the rotational speed when shifting to control, and to prevent fluctuations in the motor rotational speed and accompanying noise generation.

  Furthermore, the control means is provided with a soft start execution unit for performing a soft start control for gradually increasing the speed of the opening / closing body as time passes after the switch is turned on, and the control mode selection unit is configured to stop the stop. When the switch ON operation is performed when the opening / closing body exists in the control region, the second soft stop control may be performed without performing the soft start control. Thereby, the competition between the soft start control and the second soft stop control can be avoided. In this case, since the second soft stop control is performed from the start of the motor, it is possible to eliminate fluctuations in the rotational speed that accompany changes in the control mode, and it is possible to prevent fluctuations in the motor rotational speed and the accompanying noise generation.

  On the other hand, the opening / closing operation control method for an opening / closing body according to the present invention is an opening / closing operation control method for an opening / closing body disposed in an opening of a vehicle, and the opening / closing body performs an opening / closing operation by a user's switch ON / OFF operation. After the switch OFF operation, the speed of the opening / closing body is gradually reduced with time, and the first stop control for stopping the opening / closing body, and the opening / closing body from the predetermined stop position during the switch ON operation. A second stop control is performed to reduce the speed of the open / close body gradually based on the distance from the stop position and stop the open / close body at the stop position when reaching the predetermined stop control region; The first stop control and the second soft stop control are performed by selecting only one of them based on the position of the opening / closing body.

  In the present invention, only one of the first stop control and the second soft stop control is selected and implemented based on the position of the opening / closing body. Therefore, even if the first stop control and the second soft stop control compete, either one is implemented, and the opening / closing body can move to a predetermined stop position due to the competition between the two. The phenomenon that the motor rotation speed fluctuates and abnormal noise occurs during the movement of the opening / closing body is suppressed.

  According to the opening / closing body control system of the present invention, there is provided a control mode selection section that selects and executes only one of the first stop control accompanying the switch OFF operation and the second soft stop control based on the position of the opening / closing body. Therefore, even when the first stop control and the second soft stop control compete with each other, the competition between the two can be avoided. For this reason, it is possible to suppress such a phenomenon that the open / close body cannot move to a predetermined stop position due to the competition between the two or the motor rotation speed fluctuates and abnormal noise is generated during the movement of the open / close body. .

  According to the opening / closing operation control method of the opening / closing body of the present invention, only one of the first stop control accompanying the switch OFF operation and the second soft stop control based on the position of the opening / closing body is selected and executed. Therefore, even when the first stop control and the second soft stop control compete, the competition between the two can be avoided. For this reason, it is possible to suppress such a phenomenon that the open / close body cannot move to a predetermined stop position due to the competition between the two or the motor rotation speed fluctuates and abnormal noise is generated during the movement of the open / close body. .

Each is shown.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is an explanatory diagram showing an outline of a sunroof device to which an opening / closing body control system according to an embodiment of the present invention is applied. The sunroof device 1 is provided on a ceiling wall (roof) 2 of a passenger compartment of an automobile (vehicle) and includes a roof panel 3 that can be opened and closed as shown in FIG. An opening 4 is formed in the top wall 2, and the roof panel 3 opens and closes the opening 4. A pair of shoes 5a and 5b are fixed to both sides of the roof panel 3, respectively. On the other hand, guide rails 6 extending in the vehicle front-rear direction are fixed inside the top wall portion 2 that is both sides of the opening 4, and the shoes 5 a and 5 b are movable to the corresponding guide rails 6. Attached to. As the shoes 5a and 5b move along the guide rail 6, the roof panel 3 moves in the vehicle front-rear direction, and the opening 4 is opened and closed.

  One end of each of drive cables 7a and 7b arranged inside the top wall 2 is connected to each shoe 5b on the vehicle rear side. The drive cables 7a and 7b are geared cables, and the other ends are routed to the vehicle front side of the opening 4 respectively. A sunroof motor 9 is disposed in the front end of the top wall 2 and inside the top wall 2 between the windshield 8 and the opening 4. The gear portions of the drive cables 7 a and 7 b mesh with the drive gear 11 attached to the sunroof motor 9. When the sunroof motor 9 is operated, the drive cables 7 a and 7 b are operated in opposite directions by the drive gear 11. By the forward / reverse operation of the sunroof motor 9, the roof panel 3 is pushed and pulled by the drive cables 7 a and 7 b connected via the shoe 5 b and opens and closes in the opening 4.

  The sunroof motor 9 is a three-phase brushless motor, and is controlled by a controller (control means) 12 provided at an arbitrary part of the vehicle. The sunroof motor 9 is provided with a rotation sensor 13 (see FIG. 3), and a pulse signal is sent from the rotation sensor 13 to the controller 12 as the motor rotates. Three rotation sensors 13 are provided (13a, 13b, 13c) for detecting the direction of rotation (forward / reverse rotation) of the sunroof motor 9. The controller 12 grasps the position and operation state of the roof panel 3 based on the pulse signals output from the both rotation sensors 13a and 13b, and controls the operation of the sunroof motor 9.

  In such a sunroof device 1, when a user such as a driver operates the sunroof opening / closing switch 14, the sunroof motor 9 is activated, and the opening / closing operation of the roof panel 3 is performed. At that time, in the sunroof device 1 as well, the soft start / soft stop control (soft start / soft stop by switch operation: SW soft start / SW soft stop) as shown in FIG. Is abbreviated as “). Further, in the sunroof device 1, the fully closed / open position of the roof panel 3 is set to the automatic stop position, and the roof panel 3 is in the vicinity of the fully closed / open position (stop control region SC in FIG. When the position is about 10 mm from the fully open position, soft stop control (soft stop by position, hereinafter abbreviated as PO soft stop) as shown in FIG. 4B is performed.

  FIG. 2 is a block diagram showing a control form in the control system. As shown in FIG. 2, in normal roof panel opening / closing control, the sunroof motor 9 is controlled by the outermost route K1 in the drawing in accordance with the switch operation. That is, when the close switch is turned on in the stopped state, the sunroof motor 9 is activated by the SW soft start and operates in a steady state when the specified time T1 has elapsed (target rotational speed Nt). Thereafter, when the roof panel 3 reaches the stop control region SC near the fully closed position with the switch turned on, the roof panel 3 is controlled by PO soft stop (second stop control) and becomes fully closed. Further, when the switch is turned off while the roof panel 3 is opened / closed, that is, during the SW soft start or in the steady state, when the close switch is turned off, control by the route K2 is performed. In this case, the sunroof motor 9 shifts from SW soft start or steady state to SW soft stop (first stop control), and the roof panel 3 stops slowly.

On the other hand, as described above, when the soft start / soft stop of the switch operation and the soft start / soft stop of the position compete, the roof panel 3 may perform an operation not intended by the user. Therefore, in the control system according to the present invention, the following control (1) to (3) is performed in the vicinity of the fully closed / open position (stop control region SC and its vicinity) to avoid competition between the two. Prevents adverse effects caused by control competition. In the sunroof device 1, the same control mode is implemented in the vicinity of the fully closed position and the fully open position. Therefore, the control in the fully closed position will be described below as an example.
(1) Transition control (a)
・ During the closing operation, the switch is turned off near the fully closed position (predetermined range before the stop control area SC).
: (× SW soft stop →) PO soft stop (2) Transition control (b)
-Close switch ON near stop control area SC
: SW soft start → PO soft stop (same rotation speed)
(3) Transition control (c)
・ Close switch ON when stopped immediately before the fully closed position
: PO soft stop (× SW soft start)

  The sunroof device 1 is closed in such a setting, and the controller 12 controls the operation of the sunroof motor 9 in accordance with the state of the sunroof opening / closing switch 14. FIG. 3 is a functional block diagram showing the configuration of the controller 12. The controller 12 includes a CPU 21 that is a central processing unit, a RAM 22 that stores calculation data and the like, and a ROM 23 that stores data, programs, and the like. The ROM 23 stores a control program, data, and the like for performing the control as shown in FIG. 4 and the transition control (a) to (c) described above. In addition, the controller 12 is provided with an interface unit 24 connected to an external device such as the sunroof opening / closing switch 14 and a motor driving unit 25 which is a driving circuit for operating the sunroof motor 9 based on an instruction from the CPU 21.

  The CPU 21 is provided with a pulse count unit 31 that receives and counts pulse signals from the rotation sensors 13a and 13b. A panel position detection unit 32 and a motor rotation information calculation unit 33 are provided following the pulse count unit 31. The pulse count value calculated by the pulse count unit 31 is sent to the panel position detection unit 32, and the current position of the roof panel 3 is detected. The pulse count value and the position of the roof panel 3 have a predetermined relationship, and the relationship between the two is stored in the ROM 23 as a map 34. The panel position detection unit 32 grasps the current position of the roof panel 3 with reference to the map 34 in the ROM 23 based on the pulse count value. The motor rotation information calculation unit 33 calculates the rotation speed and rotation direction of the sunroof motor 9 (corresponding to the movement speed and movement direction of the roof panel 3) based on the pulse signal.

  The CPU 21 further determines the sunroof motor 9 based on the state of the sunroof opening / closing switch 14 (switch information), the current position of the roof panel 3 (panel position information), and the rotational speed / rotation direction of the sunroof motor 9 (motor operation information). A motor control command unit 35 that determines the operation (number of rotations / direction of rotation) is provided. The motor control command unit 35 receives switch information from the interface unit 24, panel position information from the panel position detection unit 32, and motor operation information from the motor rotation information calculation unit 33. The motor control command unit 35 determines the operation (rotation speed / rotation direction) of the sunroof motor 9 based on the switch information, panel position information, and motor operation information, and sends a motor control signal to the motor drive unit 25. Send it out. The motor drive unit 25 controls the operation of the sunroof motor 9 in accordance with an instruction from the motor control command unit 35, whereby the roof panel 3 operates.

  Here, the control system further includes a motor control command unit 35, a control mode selection unit 36, a soft start execution unit 37, a switch soft stop execution unit (first stop control unit) 38, and a position soft stop execution. A unit (second stop control unit) 39 is provided. The control mode selection unit 36 selects the control mode (soft start, steady state, SW soft stop, PO soft stop) of the sunroof motor 9 based on switch information, panel position information, and motor operation information, and if necessary. Switch accordingly.

  The soft start execution unit 37 executes SW soft start as shown in FIG. 4 based on an instruction from the control mode selection unit 36. The control mode selection unit 36 instructs the soft start execution unit 37 to perform the soft start based on the switch ON information. In response to this, the soft start execution unit 37 gradually increases the rotational speed of the sunroof motor 9 so that the moving speed of the roof panel 3 gradually increases with the open switch ON (operating the sunroof opening / closing switch 14 in the opening direction). Enlarge.

  The switch soft stop execution unit 38 executes the SW soft stop as shown in FIG. 4A based on an instruction from the control mode selection unit 36. The control mode selection unit 36 instructs the switch soft stop execution unit 38 to execute the soft stop based on the switch OFF information. In response to this, the switch soft stop execution unit 38 gradually decreases the rotational speed of the sunroof motor 9 so that the moving speed of the roof panel 3 gradually decreases after the sunroof opening / closing switch 14 is turned off.

  The position soft stop execution unit 39 executes PO soft stop as shown in FIG. 4B based on an instruction from the control mode selection unit 36. The control mode selection unit 36 instructs the position soft stop execution unit 39 to execute the soft stop based on the panel position information. In response to this, the position soft stop execution unit 39 gradually decreases the rotational speed of the sunroof motor 9 so that the moving speed of the roof panel 3 gradually decreases as the roof panel 3 enters the stop control region SC. .

  In this case, the above-described transition control (a) to (c) is performed by appropriately switching the instructions from the control mode selection unit 36 to the switch soft stop execution unit 38 and the position soft stop execution unit 39. That is, the control mode is switched according to the current position of the roof panel 3 (in the vicinity of the stop control area SC or in the vicinity thereof, etc.), and the SW soft stop or SW soft start shifts to the PO soft stop. Control transition such as PO soft stop is performed without performing SW soft start.

  In the sunroof device 1 having such a configuration, in the above-described cases (1) to (3), the state of the sunroof opening / closing switch 14, the position of the roof panel 3, the sunroof motor 9 is controlled by the motor control command unit 35 of the controller 12. Transition control (a) to (c) is appropriately executed based on the number of rotations.

(1) Transition control (a)
The control of route A in FIG. 2 is performed. This control is performed when the close switch is turned on (the sunroof opening / closing switch 14 is operated in the closing direction) and then the switch is turned off before the stop control region SC near the fully closed position. is there. Normally, SW soft stop control is performed when the switch is turned off. Here, since the switch is in the OFF state before the soft stop depending on the position is activated, the roof panel 3 is completely closed as described above. There is a risk of not being able to attend.

  Therefore, in the control system, when the close switch is turned off in the vicinity of the stop control area SC, the SW soft stop is performed until the stop control area SC is entered, and the PO soft stop is switched at the time of entry. At the time of switching from SW soft stop to PO soft stop, the current rotational speed in SW soft stop is grasped, and PO soft stop is started from the rotational speed. That is, the sunroof motor 9 is controlled so as to move from the point Q1 in FIG. 4A to the point Q2 in FIG. 4B. Thereby, it is possible to reliably close the roof panel 3 without causing a speed change due to switching.

(2) Transition control (b)
The control of route B in FIG. 2 is performed. This control is performed when the close switch is turned on near the stop control area SC. At this time, the sunroof motor 9 is switched to PO soft stop as the stop control area SC enters, but starts up with SW soft start rather than the PO soft stop rotation speed (Nt) when entering the stop control area SC. If the rotational speed is small, the rotational speed fluctuation of the difference occurs. Therefore, the control system grasps the current motor rotation speed at the SW soft start and starts PO soft stop control from the rotation speed. That is, the sunroof motor 9 is controlled so as to move from the point R1 to the point R2 in FIG. As a result, the control mode shifts from SW soft start to PO soft stop without speed change. As a result, it is possible to smoothly shift the control mode without causing a sudden change in the motor rotation speed, to suppress the unstable movement of the roof panel 3 and the generation of abnormal noise, and to suppress the user's discomfort.

(3) Transition control (c)
Control of route C in FIG. 2 is performed. This control is performed when the close switch is turned on when the sunroof is stopped in the stop control region SC. Normally, when the close switch is turned on, the sunroof motor 9 is started by SW soft start. However, since the roof panel 3 already exists in the stop control area SC, which is also the PO soft stop control area, the control modes compete. Therefore, in this control system, when the switch is turned on in this state, the PO soft stop control is performed from the beginning without performing the SW soft start. That is, together with the switch ON, the sunroof motor 9 is rotated at a rotational speed corresponding to the position, and is decelerated and stopped in the form shown in FIG. Thereby, the roof panel 3 can be closed by PO soft stop without control conflict. As a result, the roof panel 3 can be smoothly activated and stopped without causing a sudden change in the motor rotation speed, and it is possible to suppress the unstable movement of the roof panel 3 and the generation of abnormal noise, thereby reducing user discomfort. .

It goes without saying that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the invention.
For example, the range of the stop control region SC, the SW soft start execution time T1, the SW soft stop execution time T2, the PO soft stop execution range P3, etc. in the above-described embodiment can be appropriately set according to the specifications of each vehicle. is there. In the above-described embodiment, the control when the roof panel 3 is closed has been described. However, the same control can be performed when the roof panel 3 is opened. That is, it is also possible to perform transition control (a) to (c) as in (1) to (3) near the fully open position, so that the roof panel 3 can be completely opened or the opening operation can be performed. It is possible to suppress sudden speed fluctuations and abnormal noise.

  The present invention can be applied not only to an automobile sunroof device but also to an open / close body such as a slide door or a power window that is generally installed in vehicles such as industrial equipment.
