<P>PROBLEM TO BE SOLVED: To provide a door drive control device which can continuously carry out drive of door opening/closing operation even if a detection signal from a position detector indicates abnormality, provided that there is no possibility of damage or breakage of an electric motor and equipment driven by the same, to thereby eliminate a hitch such as delay of loading and unloading of passengers or delay of transportation. <P>SOLUTION: According to the door drive control device, when abnormality of a detection signal output from the position detector 5 is detected by an abnormality detector 8, a drive command computing unit 9 stops control of the door 1 opening/closing operation. Then after a predetermined time lapse from the time of abnormality detection, if the abnormality detector remains in an abnormality detection state, the door is kept in stoppage, whereas if the abnormality detector is in an abnormality non-detection state, the control of the door 1 opening/closing drive is re-started. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
