Publication number: 20190003231Abstract: During opening and closing actions of a window glass, the presence or absence of pinching of a foreign object in a window is determined on the basis of an amount of change in the movement speed of the window glass and a threshold value stored in a storage unit, and a drive direction of a motor is reversed in order to release a foreign object if it is determined that pinching is present. A threshold value update unit updates threshold values for pinching determination on the basis of the amount of change in the movement speed of the window glass for specific ranges of an entire movement range of the window glass. In addition, a threshold value for pinching determination for a range other than the specific ranges is set to be a preset fixed value.Type: ApplicationFiled: March 4, 2016Publication date: January 3, 2019Applicants: OMRON AUTOMOTIVE ELECTRONICS CO., LTD., OMRON AUTOMOTIVE ELECTRONICS CO., LTD.Inventors: Katsunori Kigoshi, Daisuke Ogawa
