Pinch Detection Based on Estimated Pinch Force
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.
