PROBLEM TO BE SOLVED: To certainly carry out smooth transfer to a closure. SOLUTION: Whether a sliding door reaches a totally closed position and a sliding door switch works to be switched off or not are judged (S4) by starting DUTY up control to gradually increase duty output to a driving motor up to 100% of the maximum value from a current duty ratio (S3) at the time when it reaches an area before total closing (S2) during constant speed control of the sliding door. Whether the closure works or not is judged by measuring a working electric current flowing to a closure unit in the case when the sliding door switch does not work to be switched off, DUTY down control is started at the time when working of the closure is confirmed, the duty output to the driving motor is lowered down to 20% of a specified value from the current duty ratio (S8), and DUTY down control is finished (S5) and working stop treatment is carried out (S6) at the time when the sliding door reaches the totally closed position (S4). |
