<p>PROBLEM TO BE SOLVED: To improve an acceleration feeling when an accelerator is stepped on at a stroke during traveling so as to accelerate again, by controlling rise time of clutch current when an electromagnetic powder clutch is engaged again, to an appropriate time value per vehicle speed. SOLUTION: Attention is paid to such a point that time required for blowing up an engine 1 is different between a case that an accelerator is stepped on at a stroke so as to accelerate again when a vehicle is traveled at a low speed and a case that the accelerator is stepped on at a stroke so as to accelerate again when the vehicle is traveled at a high speed, and in an exclusive map, relation between such a vehicle speed and rise time of clutch current is previously recorded in data and mapped. Then, the raise time of the clutch current supplied to an electromagnetic powder clutch 2 is controlled by the rise time of the clutch current read out of such a kick down exclusive map, therefore the shift down time of a continuously variable transmission and time when the electromagnetic powder clutch 2 is completed to be fastened again, are matched to each other, and the engine 1 is sufficiently raised, and adapted to the vehicle speed so as to obtain an accelerating feeling.</p> |
