Abstract

PURPOSE:To prevent an engine from abrupt reduction of rotational speed in start by setting a desired rotational speed of engine in the proximity of full closing of a throttle in idle-up higher than that in non-idle-up. CONSTITUTION:A V-belt type continuously variable transmission 10 supplies oil pressure discharged from an oil pump 42, regulated by a relief valve 40 and controlled by a pulley-controlling valve 43 and start-controlling valve 45 to an oil chamber 18 of the driven side pulley 14 and a start clutch 20 respectively. Thus, change gear ratio and torque voltage capacity of a start clutch 20 are controlled. The pulley controlling valve 43 is controlled on the basis of a desired rotational speed of engine determined according to the throttle opening. Then, a desired rotational speed of engine in the proximity of full closing of throttle in idle-up is set higher than that in non-idle-up. Thus, the rotational speed in the low throttle opening is prevented from abrupt reduction in starting.
