PURPOSE:To prevent a shock in a power transmission system and the extraordinary heating of a multiple disc clutch, by putting ON and OFF the multiple disc clutch in an optimum manner according to two control patterns. CONSTITUTION:Comparing the set number N1 of rotation with the detected number N' of rotation from a rotation speed detector 42, a comparator 35 delivers a quantity DELTAN of deviation. A switching circuit 36 compares the quantity DELTAN of deviation with an allowable quantity DELTAN' of deviation which is inputted beforehand, and makes switching to a first control means B when the quantity N is smaller than the quantity DELTAN', and to a second control means C when the former is larger than the latter. A first control storage circuit 37 stores a control pattern shown in the left figure, and a second control storage circuit 39 a control pattern in the right figure. A first computing circuit 38 computes a signal for operating an oil supplying unit 15 according to a value from the first control storage circuit 37, while a second computing circuit 40 computes said signal according to a value from the second control storage circuit 39. |
