<p>PURPOSE:To improve take-off performance by adding clutch pressure control duty to target line pressure to raise the line pressure, when clutch pressure control duty is under a prescribed value during controlling clutch pressure in take-off mode. CONSTITUTION:At take-off, a target engine speed is instituted by a deciding means 103 corresponding to a throttle opening theta, PI computation 106 is performed with deviation from the actual engine speed Ne, a feed forward quantity from a deciding means 101 is added, PID computation 109 is performed with deviation from clutch pressure Pc, and the clutch pressure control duty of a take-off clutch is output. Further, the target line pressure is instituted by a deciding means 111. When the clutch pressure control duty becomes under a prescribed value, the clutch pressure control duty of a prescribed quantity is added to the target line pressure with an adding machine 115 through a line pressure correcting means 114 to raise the line pressure. Thus, against dispersion and elapsed variation of components, control is stabilized and take-off performance can be improved.</p> |
