Abstract
PURPOSE:To make the line pressure in case when the oil leak quantity varies always equal to an aimed line pressure by correcting the duty ratio according to the corrected duty ratio quantity determined by the function between the oil temperature and the max. line pressure. CONSTITUTION:In a correction quantity searching means 97, the corrected duty ratio quantity DELTAD is obtained through the map searching according to the oil temperature To in a oil passage which is detected by an oil temperature sensor 75 and the max. line value PLMAX searched by a max. line pressure searching means 92. In a duty ratio correcting means 95, the corrected duty ratio D=Do-DELTAD is determined by subtracting the above-described corrected duty ratio quantity DELTAD from the duty ratio Do which is to be set by a duty ratio searching means 94. Thus, the line pressure PL equal to an aimed line pressure PLd can be generated by correcting the oil effluence quantity in an oil pressure system due to the increase of oil temperature and the increase of the valve clearance.
