<P>PROBLEM TO BE SOLVED: To provide an opening/closing control device that can secure safety and enables smooth operations of a train by ensuring removing of an obstacle and preventing getting-in, etc. due to excessive pushing-back of a door during the occurrence of door catching. <P>SOLUTION: An opening/closing control device of an electrically-driven door detects the occurrence of door catching due to catching of an obstacle by the door driven in a close direction by an electrical motor, generates a thrust command value which makes the thrust of the door have time series strength and drives the door based on the thrust command value. The opening/closing control device includes a position detector 5 for detecting a position of the door, a memory 8 for storing a position detection value by the position detector 5 and a pushing-back allowance when the door is moved in an open direction, and a door catching determination/command generator 7 for taking the position of the door when detecting door catching as a door catching starting position to generate the thrust command value for strengthening thrust to move the door in the close direction when the position detection value of the door pushed back in the open direction during a closing operation of the door exceeds a value obtained by adding the pushing-back allowance to the door catching starting position. <P>COPYRIGHT: (C)2012,JPO&INPIT |
