<p>The control device is of the type comprising an actuator (16) connected to a receiver (18) through a hydraulic line (17), said actuator (16) comprising a piston which, under the control of an electric motor (23) which is itself under the control of a pilot unit (24), is capable of acting on said hydraulic line (17) with, in a bypass mounted arrangement on said hydraulic line (17), a tank electrovalve (27) controlling its connection to a hydraulic fluid tank (28). According to the invention, position sensors (30, 31) detect the position of the piston (22) and of the output member (19) of the receiver (18) to send information to the pilot unit (24) and to effect a correction operation in the case of a drifting of said positions. Application to control devices for motor vehicle clutch.</p> |
