PURPOSE:To simplify construction of a device and reduce its cost, by setting a rotary speed change amount from a sum of target slip value and fixed basic slip amount and performing feedback control of friction clutch operation in accordance with a half of the rotary speed change amount. CONSTITUTION:To obtain a slip amount, an electronic control device calculates rotary slip speed between a crankshaft 4 and driven shaft 12 from an output pulse signal generated by a slip speed detecting device 132 in accordance with relative rotary speed between a plate 30 and transfer ring 26, simultaneously a rotary speed change amount A of the crankshaft 4 is calculated from roughness of the above described pulse signal, and the frequency of a solenoid valve pulse current is controlled, interlocking to the frequency of the pulse signal, to regulate oil pressure in an oil passage and control a basic slip amount to a constant value, further interlocking to A/2, pulse width of the above described pulse current is feedback controlled to adjust the oil pressure in the above described oil passage. |
