PURPOSE:To lower the clutch pressure so as to prevent the engine rotational speed from lowering by controlling the feed-back amount so as to decrease the same when a signal indicating that an accessory is energized is delivered to a control section for a continuously variable transmission. CONSTITUTION:An engine torque TRQEN is obtained from a first troupe curve table 200 in accordance with a throttle opening degree, and when an air- conditioning signal is delivered, the engine torque is multiplied by eta so as to decrease the engine torque, and then is applied with a first-order lag by means of a filter 204 so as to calculate a feed-forward amount in a computing section 206 with the use of RATC(engine rotational speed/clutch input rotational speed)XKA(proportional gain). Similarly, a signal from a second table 2020 acts upon the engine rotational speed through a filter 208 so as to give RATCXKB(proportional gain), then merges at a subtractor 214, acting upon a clutch gauge pressure and a clutch pressure through a switch 216, and produces a PWM signal through a pressure loop controller 220 and an output generator 222 so as to control the clutch pressure. |
