Patent ID: 6980897

Claim:
An oil pressure reduction rate restricting apparatus for a V-belt type continuously variable transmission in which a primary pressure is applied to a primary pulley connected to an engine side and a secondary pressure is applied to a secondary pulley connected to an output shaft, comprising: a target primary pressure calculating section that calculates a target primary pressure as a target value of the primary pressure supplied to the primary pulley; a target secondary pressure calculating section that calculates a target secondary pressure as a target value of the secondary pressure supplied to the secondary pulley; and a reduction rate restricting section that restricts rates of reduction in the target primary pressure and the target secondary pressure calculated by said target primary pressure calculating section and said target secondary pressure calculating section, respectively; and wherein said reduction rate restricting section is operable when at least one of the target primary pressure and the target secondary pressure is equal to or greater than a predetermined value, for correcting the rate of reduction in the target primary pressure or the target secondary pressure by restriction to thereby prevent a rapid decrease in the target primary pressure or the target secondary pressure.
