Openable and closable member control apparatus
View Patent ↗In a power window apparatus, which controls a lifting mechanism to drive a window glass from an opening position toward a closing position, a control unit is capable of executing: an automatic closing process that controls the lifting mechanism such that the lifting mechanism keeps driving the window glass until the window glass reaches the closing position; and a normal closing process that controls the lifting mechanism such that the lifting mechanism drives the window glass toward the closing position only throughout a time period of receiving a user operational input through an operation switch. The control unit executes only the normal closing process between the automatic closing process and the normal closing process when the operation switch receives the user operational input while the window glass is located within a predetermined section in a movable range of the window glass.
1. An openable and closable member control apparatus comprising:
a drive device that is operable to drive an openable and closable member to move the openable and closable member from an opening position, at which the openable and closable member opens an opening, toward a closing position, at which the openable and closable member closes the opening;
an operational input device, through which a user inputs a user operational input for moving the openable and closable member; and
a control device that controls the drive device according to the user operational input that is inputted through the operational input device, wherein:
the control device is operable to execute:
a first control process that controls the drive device such that the drive device keeps driving the openable and closable member until the openable and closable member reaches the closing position; and
a second control process that controls the drive device such that the drive device drives the openable and closable member toward the closing position only throughout a time period of receiving the user operational input through the operational input device; and
the control device executes only the second control process between the first control process and the second control process when the operational input device receives the user operational input while the openable and closable member is located within a predetermined section in a movable range of the operable and closable member.
2. The openable and closable member control apparatus according to claim 1 , comprising a determining device that senses a change in an operational state of the drive device and determines whether pinching of a foreign object with the openable and closable member is present based on a sensed result of the change in the operational state of the drive device, wherein:
when the determining device determines that the pinching of the foreign object is present during execution of the first control process, the control device executes a reverse control process that controls the drive device such that the drive device drives the openable and closable member toward the opening position;
execution of the reverse control process by the control device is limited until an amount of movement of the drive device, which is measured from a time of staring an operation of the drive device, reaches a predetermined amount; and
the predetermined section is set based on the closing position, and the predetermined amount.
3. The openable and closable member control apparatus according to claim 2 , wherein:
the determining of whether the pinching of the foreign object with the openable and closable member is present at the determining device is limited when the openable and closable member is located in a determination non-executing range that is set to have the closing position as an end of the determination non-executing range in the moveable range of the openable and closable member; and
the predetermined section is set based on the closing position, the determination non-executing range, and the predetermined amount.
4. The openable and closable member control apparatus according to claim 3 , wherein:
the drive device drives the openable and closable member that is movable to open or close the opening formed in a vehicle;
when the openable and closable member is moved at a location adjacent to the closing position, the drive device drives the openable and closable member against a frictional force that is exerted between a contacting member, which is located at an edge part of the opening, and the openable and closable member; and
the predetermined section is set based on the closing position, the determination non-executing range, an end position of the contacting member in a moving direction of the openable and closable member, and the predetermined amount.
5. The openable and closable member control apparatus according to claim 1 , wherein:
the operational input device is a switch, which is operable in two steps; and
when a portion of the switch, which is operable by the user to move the openable and closable member to the closing position, is operated to a first step position and is then further operated to a second step position, the operational input device receives the user operational input that demands execution of the first control process.
