Control device of opening and closing member
First Claim
1. A control device of opening and closing member comprising:
- a driving means for driving, by means of a duty ratio control, an opening and closing member to be opened or closed relative to an opening portion provided on a structure;
a speed detecting means for detecting a moving speed of the opening and closing member; and
a controlling means for driving the opening and closing member based on a position of the opening and closing member, and stopping or reversing a movement of the opening and closing member when a movement of the opening and closing member is inhibited between the opening and closing member and the structure;
wherein the controlling means includes a target speed determining means for determining a target speed of the opening and closing member, a speed estimating means for estimating a moving speed of the opening and closing member, a control speed determining means for determining a control speed of the opening and closing member based on an estimated speed estimated by the speed estimating means and the target speed, a duty ratio determining means for providing a duty ratio to the driving means every predetermined number of periods so that a speed of the opening and closing member reaches the control speed, and increasing a duty ratio when a speed of the opening and closing member becomes below the target speed, a duty ratio difference calculating means for calculating a difference between a present duty ratio and a duty ratio before a predetermined number of periods, and a movement inhibition detecting means for detecting that a movement of the opening and closing member is inhibited when the duty ratio difference exceeds a reference value.

Abstract
A control device of opening and closing member includes a driving means for driving, by means of a duty ratio control, an opening and closing member, a speed detecting means, and a controlling means for driving the opening and closing member based on a position of the opening and closing member, and stopping or reversing a movement of the opening and closing member. The controlling means includes a duty ratio determining means for providing a duty ratio to the driving means every predetermined number of periods so that a speed of the opening and closing member reaches the control speed, and increasing a duty ratio when a speed of the opening and closing member becomes below the target speed, and a duty ratio difference calculating means for calculating a difference between a present duty ratio and a duty ratio before a predetermined number of periods.
