PROBLEM TO BE SOLVED: To provide a control device of a continuously variable transmission capable of improving shift responsiveness.SOLUTION: In shift control of a CVT 4, a control command value is output from a PID controller portion 112 to set a duty ratio of solenoid valves 104, 105 for shifting. A relationship between a characteristic value according to characteristics of the solenoid valves 104, 105 for shifting and the control command value is stored in a memory of a CVTECU 101. During the shift control, the control command value output from the PID controller portion 112 is acquired, and the characteristic value corresponding to the control command value is acquired on the basis of the relationship stored in the memory. Then the control command value is corrected according to the characteristic value corresponding to the characteristics of the solenoid valves 104, 105 for shifting, a duty ratio according to the control command value after the correction is set, and the solenoid valves 104, 105 for shifting are controlled with the duty ratio.SELECTED DRAWING: Figure 2 |
