Method and system for detecting a resistive force applied against a car window.

摘要

Method for detecting the presence of a trapped between an automotive window (18) and a respective frame (14), comprising object: (i) providing an opening and closing a window (18) through a regulator (22) controlled by a motor electric drive commutator (20) controlled by a control circuit (24) and fed through an electric line li- (65) including a commutator motor shaft (32) and a granaje en- ( 34) associated therewith which cooperates with a second meshed je (36) of an output (38) coupled to the controller; (Ii) detecting a resistive torque applied to the regulator and generating a signal having a value proportional to the resistive torque; (Iii) transmitting the signal to the control circuit via the power line; and (iv) processing the signal to determine if an object is caught between the window and a respective frame; It characterized in that the signal is transmitted via the motor brush-commutator armature connection using technology Carrier (PLC).
