Abstract
When a switch condition where a shift of a continuously variable transmission is switched from a first shift that is any one of an upshift and a downshift to another second shift is satisfied, an integral term in the feedback control of the first shift is reduced to zero with a first predetermined gradient, an operation of an integral term in the feedback control of the second shift is started after the switch condition is satisfied and before the integral term in the feedback control of the first shift reaches zero, and the continuously variable transmission is shifted based on a sum of the integral term in the feedback control of the first shift and the integral term in the feedback control of the second shift.
