Abstract
This invention aims to prevent an obstacle from being trapped between a vehicle window and a window frame. A supersonic wave f is emitted into a vehicle window W. A reflection wave i of the supersonic wave is received to decide whether the reflection wave i is one reflected from peripheral faces of a target to be detected or not. If the received reflection wave i is one reflected from the peripheral faces from the target, a driving motor M for the vehicle window W is stopped. Thus, when an obstacle contacts with the peripheral faces of the vehicle window, it is possible to previously prevent the obstacle from being caught by the window since a driving source for the vehicle window is stopped.
