<p>PURPOSE:To making a sliding state of a powder clutch to follow up an objective sliding state by compensating a given quantity of a transfer torque increased or decreased based on a parameter reflected a sliding state of a magnetic particle type electromagnetic clutch. CONSTITUTION:A powder clutch 2 is provided between an output shaft 11 of an engine 1 and an input shaft 31 of a continuously variable transmission (CVT) 3A. An electronic control part 4 controls the powder clutch 2 and CVT 3A by dected values from sensors provided to the enging 1, powder clutch 2, CVT 3A, an output shaft 33B of a sub transmission 3B, and a speed ratio control device etc. Controlled values inputted into an output port 49a of the electronic control part 4 are added to the powder clutch 2 and the speed ratio control device 5 via electromagnetic valve drive parts 49b aid 49c and exciting coil driving parts 49d and a transfer torque control of the clutch 2 and the speed ratio control of the CVT 3A are carried out.</p> |
