The block diagram which shows the electric constitution of one Embodiment of this invention. The flowchart which shows the control aspect of the embodiment.

Hereinafter, an embodiment in which the present invention is applied to a power slide door system of a vehicle such as an automobile will be described with reference to the drawings.
FIG. 1 is a block diagram showing an electrical configuration of the present embodiment. As shown in the figure, a door ECU (Electronic Control Unit) 10 installed in the vehicle body is mainly composed of, for example, a micro controller (MCU), and power as drive means also installed in the vehicle body. The slide door device 20 is electrically connected. The power slide door device 20 is linked to a slide door 1 as a door through an appropriate transmission mechanism (not shown). The sliding door 1 is supported on a side portion of the vehicle body through an appropriate support member (not shown) so as to be movable in the front-rear direction, and opens and closes the opening for getting on and off in accordance with the movement in the front-rear direction. . The door ECU 10 electrically opens and closes the sliding door 1 by driving control of the power sliding door device 20.

  That is, the power slide door device 20 includes a door motor 21, an electromagnetic clutch 22, and a pair of pulse sensors 23. The door ECU 10 controls the opening / closing operation of the sliding door 1 by drivingly controlling the door motor 21. Further, the door ECU 10 controls the driving of the electromagnetic clutch 22 to switch the power transmission between the door motor 21 and the slide door 1 between connection and disconnection. This is because the power transmission is set to a connected state only when the slide door 1 is electrically opened / closed and the slide door 1 is opened / closed manually to realize a smooth opening / closing operation. . Further, the door ECU 10 determines the rotation direction (forward or reverse) and rotation amount of the door motor 21 (more precisely, the output shaft of the electromagnetic clutch 22) based on the pair of pulse signals with different phases output from both pulse sensors 23. And the rotational speed, that is, the opening / closing position and opening / closing speed of the slide door 1 are detected. The door ECU 10 controls the opening / closing operation of the slide door 1 by the power slide door device 20 based on the pulse signals from the pulse sensors 23.

  The door ECU 10 is electrically connected to a latch mechanism (not shown) that holds the slide door 1 in a fully closed state or a fully open state, and a release motor 11 and a closer motor 12 that are linked via an appropriate transmission mechanism. ing. The release motor 11 transmits the power to the latch mechanism, thereby releasing the holding of the slide door 1 in the fully closed state or the fully open state by the latch mechanism. Thereby, the slide door 1 will be in an openable state or a closeable state. On the other hand, the closer motor 12 transmits the power to the latch mechanism, thereby holding the slide door 1 in the half door state in the fully closed state by the latch mechanism.

  In addition, the door ECU 10 is electrically connected to, for example, a driver seat operation switch 15 installed on the dashboard facing the driver seat side. The door ECU 10 controls the opening / closing operation of the slide door 1 by the power slide door device 20 based on the operation signal when the driver's seat operation switch 15 (push button) is pushed by the driver (user). . Further, the door ECU 10 is electrically connected to an inside handle switch 16 and an outside handle switch 17 respectively installed on the inside door handle IH and the outside door handle OH. The door ECU 10 opens and closes the slide door 1 by the power slide door device 20 based on an operation signal from the inside handle switch 16 or the outside handle switch 17 in accordance with the operation of either the inside door handle IH or the outside door handle OH. Control etc. The inside door handle IH or the outside door handle OH serves as a handshake when the sliding door 1 is manually opened and closed on each of the vehicle compartment side and the vehicle exterior side. Further, the door ECU 10 is electrically connected to a latch switch 18 installed in the latch mechanism. The door ECU 10 operates from a latch switch 18 according to the operating position of the latch mechanism (the position where the slide door 1 is held in the fully closed state or the fully opened state, the position where the slide door 1 is held in the half door state, or the position where the slide door 1 is released). Based on this detection signal, the opening / closing operation of the sliding door 1 by the power sliding door device 20 is controlled.

  On the other hand, the door ECU 10 is electrically connected to the in-vehicle device 31 mounted on the vehicle body. The in-vehicle device 31 constitutes a wireless communication system with the portable device 36 carried by the user, and receives a transmission signal accompanying the pressing operation of the wireless switch 36a (push button) of the portable device 36. Is transmitted to the door ECU 10. The door ECU 10 controls the opening / closing operation of the slide door 1 by the power slide door device 20 based on a signal from the in-vehicle device 31.

  The driver's seat operation switch 15, the inside handle switch 16, the inside door handle IH, the outside handle switch 17, the outside door handle OH, and the wireless switch 36a constitute a door opening / closing operation means and a door half-opening operation means. The push button of the driver's seat operation switch 15, the inside door handle IH, the outside door handle OH, and the push button of the wireless switch 36a respectively constitute operation members.

  Here, the drive control aspect of the power slide door apparatus 20 by the door ECU 10 will be described. For convenience, description of drive control modes of the release motor 11 and the closer motor 12 by the door ECU 10 is omitted. It goes without saying that the drive control of the release motor 11 and the closer motor 12 is performed in conjunction with the opening / closing operation of the slide door 1 according to the door state.

  For example, while the sliding door 1 is stopped, any one of the driver seat operation switch 15 (push button), the inside door handle IH, the outside door handle OH, and the wireless switch 36a (push button) is operated once to operate the driver seat. When an operation signal or the like from the switch 15 is input, the door ECU 10 starts an opening / closing operation (hereinafter also referred to as “normal operation”) of the slide door 1. That is, the door ECU 10 drives the electromagnetic clutch 22 to switch the power transmission between the slide door 1 and the door motor 21 to the connected state, and drives the door motor 21 to open and close the slide door 1. At this time, the door ECU 10 drives and controls the door motor 21 based on the pulse signal from the pulse sensor 23. Specifically, the door ECU 10 selects the rotation direction of the door motor 21, that is, the operation direction of the slide door 1 based on the opening / closing position of the slide door 1 when an operation signal or the like from the driver seat operation switch 15 is input. At the same time, the drive of the door motor 21 is continued until the slide door 1 reaches the fully open position or the fully closed position. That is, the door ECU 10 receives the operation signal from the driver's seat operation switch 15 once and starts to drive the door motor 21 to open / close the slide door 1. When the fully closed position is reached, the drive of the door motor 21 is stopped to stop the slide door 1 (opening / closing control means).

  During the opening / closing operation of the slide door 1, any one of the driver's seat operation switch 15 (push button), the inside door handle IH, the outside door handle OH, and the wireless switch 36a (push button) is operated once to drive When an operation signal or the like is input from the seat operation switch 15, the door ECU 10 starts the reversal / stop operation of the slide door 1. Specifically, the door ECU 10 reverses the rotation direction of the door motor 21 to reverse the operation direction of the slide door 1, and when the slide door 1 moves a certain distance after starting the reverse operation, the door motor 10 21 is stopped. This is because, for example, when the user accidentally starts the opening / closing operation of the slide door 1, the operation is interrupted.

  On the other hand, while the sliding door 1 is stopped, any one of the driver's seat operation switch 15 (push button), the inside door handle IH, the outside door handle OH, and the wireless switch 36a (push button) is continuously 2 within a predetermined time. When the operation signal is continuously input from the driver's seat operation switch 15 by the turning operation, the door ECU 10 starts the halfway stop reservation operation of the slide door 1. That is, the door ECU 10 drives the electromagnetic clutch 22 to switch the power transmission between the slide door 1 and the door motor 21 to the connected state, and drives the door motor 21 to open and close the slide door 1. At this time, the door ECU 10 drives and controls the door motor 21 based on the pulse signal from the pulse sensor 23. Specifically, the door ECU 10 rotates the door motor 21 based on the opening / closing position of the sliding door 1 at the time when an operation signal from the driver's seat operation switch 15 is continuously input, that is, the operation of the sliding door 1. While selecting a direction, the drive of the door motor 21 is continued until the slide door 1 reaches a predetermined half-open position. That is, the door ECU 10 stores the half-open position in the storage area, and stops the driving of the door motor 21 when the open / close position of the slide door 1 detected by the pulse sensor 23 coincides with the half-open position. That is, the door ECU 10 receives the operation signal from the driver's seat operation switch 15 twice in succession, thereby starting the drive of the door motor 21 to open and close the slide door 1, and the slide door 1 When reaching the half-open position, the drive of the door motor 21 is stopped to stop the slide door 1 (half-open control means). Therefore, for example, when the operation signal from the driver's seat operation switch 15 is continuously input twice in the fully closed position of the slide door 1, the slide door 1 starts to open and the slide door 1 Stop when it reaches the half-open position. The predetermined half-open position is set based on, for example, the minimum door opening at which an occupant can get on and off the vehicle.

  In addition, during the opening / closing operation of the slide door 1, any one of the driver's seat operation switch 15 (push button), the inside door handle IH, the outside door handle OH, and the wireless switch 36a (push button) is continuously performed within a predetermined time. When the operation signal or the like is continuously input from the driver's seat operation switch 15 by being operated twice, the door ECU 10 starts the halfway stop reservation operation of the slide door 1. Specifically, the door ECU 10 stops the sliding door 1 by stopping the driving of the door motor 21 when the sliding door 1 in the opening / closing operation reaches the half-open position (half-open control means).

  If the sliding door 1 that is being opened and closed has passed the half-open position in the operating direction at the time when the operation signal from the driver seat operation switch 15 is input twice in succession, May be invalidated or the opening / closing operation of the slide door 1 may be stopped at the current position. Alternatively, the reversing operation may be stopped when the sliding door 1 reaches the half-open position after the sliding door 1 being opened and closed is reversed. For example, when an operation signal or the like from the driver's seat operation switch 15 is continuously input twice in a state where the sliding door 1 being opened has passed the half-open position, the sliding door 1 is reversed (closed). When the half-open position is reached, the slide door 1 is stopped.

  Next, the drive control mode of the power slide door device 20 by the door ECU 10 will be described collectively based on the flowchart of FIG. This process is repeatedly executed by a scheduled interruption every predetermined time.

  When the processing shifts to this routine, it is determined whether or not there is an operation by the user based on an operation signal from the driver seat operation switch 15 (S1). When it is determined that there is an operation by the user, it is determined based on the pulse sensor 23 or the like whether or not the slide door 1 is stopped (S2). Here, if it is determined that the slide door 1 is stopped, it is determined whether or not the operation determined in S1 is an operation (twice operation) that causes the slide door 1 to perform an intermediate stop reservation operation (S3). When it is determined that the operation is not a reservation operation, the normal operation is started and the slide door 1 is opened / closed toward the fully open position or the fully closed position (S5). The stop reservation operation is started, and the slide door 1 is opened and closed toward the half-open position (S6).

  On the other hand, if it is determined in S2 that the slide door 1 is not stopped (opening / closing operation), it is determined whether or not the operation determined in S1 is an operation (second operation) for causing the slide door 1 to perform an intermediate stop reservation operation. (S4). Then, if it is determined that the operation is not a reservation operation, the reversal / stop operation is started and the slide door 1 is reversed (S7). If it is determined that the operation is a reservation operation, an intermediate stop reservation operation is started. Then, the sliding door 1 is opened and closed toward the half-open position (S8).

  If any of the processes of S5 to S8 is started, or if it is determined in S1 that there is no operation by the user, the subsequent processes are once ended. That is, when one of the processes from S5 to S8 is started based on an operation by the user, the process is continued until the corresponding process is completed unless it is determined that there is a new operation by the user.

As described above in detail, according to the present embodiment, the following effects can be obtained.

That is, the door ECU 10 changes and controls the half-open position at which the slide door 1 is stopped based on the detection signal when the change operation means 41 is adjusted (switched) by the user. In this case, the half open position where the slide door 1 stops is changed by the change operation means 41, so that the degree of freedom in setting the usable half open position can be improved. Then, the user can stop the slide door 1 in a state closer to the desired half-open position.
