Abstract
A controller writes position information (count value) of the window glass into an EEPROM based on halting of operation of a drive motor and identifies the current position of the window glass based on the position information of the window glass written in the EEPROM at the start of power supply. The controller determines whether the current position of the window glass has been lost or not at the start of power supply. Only when the controller determines that the current position of the window glass has been lost at the start of power supply, the controller shifts to a mode of performing relearning of the origin position for matching the position of the window glass with the position of the window glass corresponding to the position information written into the EEPROM.
Claims28
A control apparatus for an open/close member, in which the apparatus controls opening and closing of the open/close member, comprising:
- a drive motor driven so as to open and close the open/close member;
- position detection means for detecting the position of the open/close member;
- storage means made of an electrically rewritable ROM into which position information corresponding to the position of the detected open/close member is written;
- control means for writing current position information of the open/close member into the storage means based on halting of operation of the drive motor and identifying the current position of the open/close member when power supply is started based on the position information of the open/close member written in the storage means;
- and
- determination means for determining whether the control means has lost the current position of the open/close member or not at the start of the power supply.
A method for controlling an open/close member, in which the method controls opening and closing of the open/close member, comprising:
- writing position information corresponding to a detected position of the open/close member into storage means made of an electrically rewritable ROM based on the halting of operation of a drive motor which opens and closes the open/close member;
- identifying the current position of the open/close member by control means at the start of power supply based on the current position information of the open/close member written in the storage means;
- and
- determining at the start of the power supply that the control means has lost the current position of the open/close member or not.
A control apparatus for an open/close member, in which the apparatus controls opening and closing of the open/close member, comprising:
- a drive motor driven so as to open and close the open/close member;
- position detection apparatus for detecting the position of the open/close member;
- an electrically rewritable ROM into which position information corresponding to the position of the detected open/close member is written;
- a controller for writing current position information of an open/close member into the ROM based on halting of operation of the drive motor, identifying the current position of the open/close member when power supply is started based on the position information of the open/close member written in the ROM and determining whether the current position of the open/close member has been lost or not at the start of the power supply.
A method for controlling an open/close member, in which the method controls opening and closing of the open/close member, comprising:
- writing position information corresponding to a detected position of the open/close member into an electrically rewritable ROM based on the halting of operation of a drive motor which opens and closes the open/close member;
- identifying the current position of the open/close member with a controller at the start of power supply based on the current position information of the open/close member written in the ROM;
- and
- determining at the start of the power supply that the controller has lost the current position of the open/close member or not.
