Embodiment Construction
[0052] The method for controlling the electric window of an automobile according to the present invention and the anti-pinch controller for the electric window designed according to the method of the present invention will now be introduced in conjunction with accompanying drawings 1 to 3 of the specification.
[0053] As shown in Figures 1 to 3, where:
[0054] U-motor armature voltage, I-armature current, 101-armature winding, 102-motor load, 103-sampling resistance, 104-electric window glass, 105-door, q-electric window glass position.
[0055] And when q=0, it means the glass is at the bottom, and when q=Q, it means the glass is at the top.
[0056] Motor drive part: the single-chip microcomputer U1 sends a control signal, drives the relays K1 and K2 through the transistors Q1 and Q2, and controls the forward rotation, reverse rotation and stop of the electric window DC motor M.
[0057] Signal processing part: the armature current signal of the DC motor, through the samp...
