Abstract:
A first target secondary pulley pressure Psteng is calculated based on an output torque Teng of an engine, and then an offset value Psteng+PO is calculated by adding a predetermined offset PO to the first target secondary pulley pressure Psteng. The first target secondary pulley pressure Psteng is outputted as a target secondary pulley pressure Ps(n) when a target secondary pulley pressure Ps(n−1) in a previous control cycle is less than or equal to the first target secondary pulley pressure Psteng; the offset value Psteng+PO is outputted as the target secondary pulley pressure Ps(n) when the target secondary pulley pressure Ps(n−1) in the previous control cycle is greater than or equal to the offset value Psteng+PO; and otherwise, the target secondary pulley pressure Ps(n−1) in the previous control cycle is outputted as the target secondary pulley pressure Ps(n), thereby suppressing an oscillation in the target secondary pulley pressure Ps(n).
