PROBLEM TO BE SOLVED: To prevent a bite from being erroneously determined in drive control of an opening/closing body. SOLUTION: In this drive control method in which an averaged period tar (n) obtained from rotating speed detected signal weighted mean is compared with a rotation period t (n), and when the condition of the rotation period t (n) longer than the averaged team tav (n) is continued over a fixed section B (number of control cycle), it is judged to be in a bite and bite preventing process is performed, the initial value tav (o) of the averaged period is added to the initial rotation period t (o) by a fixed value d, and the computed value of the averaged period tav (o) in the section of some extent immediately after starting is swelled bulk. Even when the rotation period t (n) increases directly after starting by a flat high load or the like, because the section of the rotation period t (n) exceeding the averaged period is short, and increase of the rotation period t (n) due to a high load or the like immediately after starting is not erroneously judged to be in a bite, the drive control of an opening/closing body judging the bite can be made to be of higher quality. |
