ABSTRACT:
A window opening and closing controller for stably detecting jamming without having any influence on jamming load even when power voltage is changed is to be provided. In a window opening and closing controller for detecting jamming of a foreign substance on the basis of a comparing result of a changing amount of the rotational speed of a motor for opening and closing a window and a predetermined threshold value, and controlling the operation of the motor so as to open the window when there is jamming, the threshold value is constructed by a first threshold value at a normal time and a second threshold value as a reference gentler than this first threshold value. The threshold value is changed from the first threshold value to the second threshold value on the basis of the detection of closing of a door. The threshold value is returned from the second threshold value to the first threshold value on the basis of the detection of the rotation of the motor by a predetermined rotating amount in a state in which the threshold value is set to the second threshold value.
