Method of compensating for abrupt load changes in an anti-pinch window control system
First Claim
1. A method of compensating for abrupt load changes in an anti-pinch window control system comprising:
- measuring an instantaneous torque value during operation of a window lift mechanism;
calculating a pinch factor based on the instantaneous torque value and a stored torque value; and
adjusting a pinch threshold based on the pinch factor to define a modified pinch threshold.

Abstract
A method of compensating for abrupt load changes in an anti-pinch window control system (300) includes measuring an instantaneous torque value (412) of a window lift mechanism (200) and calculating a pinch factor (430) based on the instantaneous torque value (412) and a stored torque value (424). A pinch threshold (308) is then adjusted based on the pinch factor (430) to define a modified pinch threshold (432). Stored torque value (424) includes stored torque values from sections of travel (406) of window (104), stored downstroke torque values (428) and stored upstroke torque values (426).
