ANTI-PINCH METHOD FOR AN APPARATUS FOR AUTOMATIC MOVEMENT OF SLIDING WINDOWS IN A MOTOR VEHICLE, IN PARTICULAR A POWER-WINDOW APPARATUS, AND CORRESPONDING DEVICE

摘要

An anti-pinch method for an apparatus for automatic movement of sliding windows including the steps of: receiving at least one electrical quantity (e_a, i_a) of the motor (M); counting (R_c) oscillation periods (R_d) of the at least one electrical quantity (e_a, i_a); calculating an angular position (θ(t)) of the motor (M) as a function of the number of periods (R_c) of the electrical quantity (e_a, i_a); calculating a position of the window (F) as a function of said angular position (θ(t)) of the motor (M); and reversing the direction of rotation of the motor (M) if the position of the window (F) falls within an anti-pinch zone (APZ) and the movement of the motor (M) is at least partially blocked.
