Abstract
When gear shift to second gear shift stage is completed and frictional engagement element is judged to be in slip state by slip state judging unit in a state in which input torque is input torque upper limit value, a value obtained by subtracting first predetermined amount from the input torque upper limit value is set as a decrease side input torque upper limit value. When next gear shift to the second gear shift stage is completed with the decrease side input torque upper limit value set and the frictional engagement element is not judged to be in slip state by the slip state judging unit in a state in which the input torque is the decrease side input torque upper limit value, a value obtained by adding second predetermined amount to the decrease side input torque upper limit value is set as a new input torque upper limit value.
