Abstract

A controller prestores average moving speed data, which corresponds to respective corresponding positions of a window glass of a door driven by a motor at the time of the closing movement of the window glass, as learning data. The controller senses pinching of an object by the window glass based on the learning data and the speed measurement signal obtained at the time of the closing movement of the window glass. The controller senses a disturbance when the speed measurement signal obtained at the time of the closing movement of the window glass exceeds a predetermined value. The controller updates the learning data based on the average moving speed data at the time of the closing movement of the window glass. The controller controls execution and non-execution of updating of the learning data in response to a close state and an open state of the door.
