Abstract
An opening/closing member control device includes a control section configured to control a motor for opening and closing an opening/closing member and determine whether an entrapment occurs when closing the opening/closing member. The control section is further configured to supply a prestored drive voltage to the motor when closing the opening/closing member, and maintain supply of the prestored drive voltage until it is determined that an entrapment has occurred, even if the acquired load information fluctuates.
Claims12
An opening/closing member control device comprising a control section configured to:
- control a motor to open and close an opening/closing member;
- acquire load information when closing the opening/closing member;
- and
- determine whether an entrapment has occurred based on the load information,
- wherein the control section is further configured to
- when closing the opening/closing member, supply to the motor a drive voltage that is set and stored in advance so that the opening/closing member moves at a constant moving speed, the drive voltage corresponding to each of a plurality of positions of the opening/closing member, and
- during a period in which the opening/closing member is being closed, and even if the acquired load information fluctuates, maintain supply of the drive voltage that is set and stored in advance until it is determined that an entrapment has occurred, and
- wherein the load information is any one of a rotation speed of the motor, a value of current flowing through the motor, and a motion speed of the opening/closing member.
An opening/closing member control device comprising one or more processors programmed to:
- control a motor to open and close an opening/closing member;
- acquire load information when closing the opening/closing member;
- and
- determine whether an entrapment has occurred based on the load information,
- wherein the one or more processors are further programmed to
- when closing the opening/closing member, cause to be supplied to the motor a drive voltage that is set and stored in a memory in advance so that the opening/closing member moves at a constant moving speed, the drive voltage corresponding to each of a plurality of positions of the opening/closing member, and
- during a period in which the opening/closing member is being closed, and even if the acquired load information fluctuates, cause to be maintained supply of the drive voltage that is set and stored in the memory in advance until it is determined that an entrapment has occurred, and
- wherein the load information is any one of a rotation speed of the motor, a value of current flowing through the motor, and a motion speed of the opening/closing member.
