Abstract
A method of compensating for abrupt load changes in an anti-pinch window control system ( ) includes measuring an instantaneous torque value ( ) of a window lift mechanism ( ) and calculating a pinch factor ( ) based on the instantaneous torque value ( ) and a stored torque value ( ). A pinch threshold ( ) is then adjusted based on the pinch factor ( ) to define a modified pinch threshold ( ). Stored torque value ( ) includes stored torque values from sections of travel ( ) of window ( ), stored downstroke torque values ( ) and stored upstroke torque values ( ).
