Pinch detection device at opening/closing section, vehicle having the device, and method for detecting pinch at the opening/closing section

Abstract

The present invention provides a pinch detection device at an opening/closing section having a very simple structure that can surely detect pinch without a faulty operation also in a vehicle whose power supply voltage greatly fluctuates, a vehicle having this device, and a method for detecting pinch at an opening/closing section. This invention is a pinch detection device at an opening/closing section includes a sensor for detecting displacement of a opening/closing section of a vehicle to be opened/closed by a motor, a time counter for counting a relative time adjusted according to a fluctuation in a power supply voltage, and a pinch detector for detecting pinch of a foreign matter at the opening/closing section according to a change in a relative speed obtained based on a change in the displacement on a basis of the relative time.
