PURPOSE: To substantially simultaneously open and close plural windows in a short time by driving the respective windows with the delay time which is different between the starting time of the window and the lock operating time. CONSTITUTION: At the time of starting plural windows by a power window motor 4, the peak value of a driving current of the power window motor 4 is obtained corresponding to the respective windows. Subsequently, the mutual overlap of the peak values is eliminated and a different delay time is set to start the power window motor 4. Also at the time of locking the window, a mutual overlap of peak values of a driving current of each window motor 4, and a different delay time is set to conduct the lock operation. Thus, plural windows can be started and locked substantially simultaneously so that the driving time for the windows can be reduced remarkably as compared with the conventional device. |
