Abstract
A power closure system with anti-pinch having a closure, a motor operatively connected to the closure, a sensor operatively producing signals indicative of motor speed, an anti-pinch activator coupled to the sensor and the motor, the anti-pinch activator including a predetermined trigger value; a measured value; a stored value; a comparator for comparing the measured value with the stored value and initiating a pinch response when the difference between the measured value and the stored value is greater than the trigger value; and a predetermined modifying calculation for changing the stored value when the measured value indicates a motor speed less than the motor speed indicated by the stored value.
