<P>PROBLEM TO BE SOLVED: To provide a small-type sliding restraining control device of an electromagnetic clutch capable of enhancing joining force, by eliminating sliding when joining by saved electric power consumption. <P>SOLUTION: This clutch sliding restraining control device includes an electric current impressing means capable of impressing an electric current even in any direction of joining and releasing on the electromagnetic clutch by an H bridge type electric circuit, a predicting means for predicting the sliding of the electromagnetic clutch from a torque difference between an engine and an air compressor, a joining force estimating means for estimating the joining force of the required electromagnetic clutch from a rotating speed difference between the engine and the air compressor, an electric current value calculating means for calculating an electric current value optimal for joining the electromagnetic clutch from the estimated joining force, and a changing means for changing the duty ratio by the calculated optimal electric current value. When the predicting means predicts the sliding of the electromagnetic clutch, the changing means changes the duty ratio so as to strengthen the joining force between the engine and a motor generator. <P>COPYRIGHT: (C)2013,JPO&INPIT |
