Abstract: The pinch detector includes a torque estimator that estimates a motor torque from current values of physical quantities of the motor including a motor voltage, a motor current and a motor speed, using coefficients of an approximation function that calculates an energy conversion efficiency of the motor as a function of the motor torque; a converter that calculates a first estimation of a pinch force exerted by the opening and closing member on a pinched object by converting the estimated motor torque into an estimated pinch force using a torque to force conversion coefficient; a comparator that compares the estimated pinch force with a predetermined force limit in order to detect a pinch based on the comparison result.

Abstract: A method for detecting potential pinches caused by at least one powered movable panel between a closed position and an open position, by: measuring a physical quantity at a plurality of panel positions when the panel is moved towards the open position so as to get a first profile, measuring said physical quantity in a reference position, when the panel is moved towards the closed position, and determining an offset value, determining a second profile by shifting the first profile of a shifting value, measuring said physical quantity in a repetitive manner when the panel is moved towards the closed position so as to get a third profile, and detecting a potential pinch if the third profile crosses the second profile.
