摘要
An apparatus for automatic movement of sliding windows in a motor vehicle, comprising a d.c. electric motor that moves a window (F) so that it slides along guides, including an electronic control module for controlling the d.c. electric motor, in particular a microprocessor. The electronic control module measures a current (I) of the motor and a position (X) of the window (F), and drives reversal of operation of the electric motor if it is verified that the current (I) is higher than a threshold current (Ith) and the position (X) of the window (F) falls within a given zone (APZ) of a path (P) of movement of the window (F). The anti-pinch circuit device measures a back electromotive force (E; Em) of the motor, and the electronic control module calculates the position of the window (F) as a function of the back electromotive force (E; Em) of the motor.
