Abstract
The pinch detector is suitable to detect a pinch at a closing member actuated by a motor equipped with a measuring circuit to measure a motor current. It includes a first portion that, when the motor starts closing the member, obtains a reference value of the motor current measured at the end of a blind time period having a predetermined duration from the moment the motor starts to close the member; a second portion that compares current values of the measured motor current to a threshold value depending on said reference value, during a detection time period, following the blind time period and preceding a steady state time period of the motor, in order to detect a pinch at the closing member based on a comparison result.
