Opening / closing section pinching determination device, vehicle equipped with the apparatus, and opening / closing section pinching determination method

摘要

An opening / closing portion pinching determination device that can reliably determine pinching without causing malfunction even in a vehicle with a large fluctuation in power supply voltage even though it has an extremely simple configuration, a vehicle equipped with the device, and an opening / closing portion of the opening / closing portion Provided is a pinching determination method. The present invention includes a sensor that detects a displacement amount of an opening / closing part of a vehicle that is opened and closed by a motor, a time measuring part that measures a relative time adjusted in accordance with fluctuations in a power supply voltage, and the displacement based on the relative time. An opening / closing part pinching determination device comprising: a pinching determination unit that determines whether foreign objects are pinched in the opening / closing part based on a change in relative speed obtained from a change in amount.
