Abstract: A controller for a continuously variable transmission includes an electronic control unit. The electronic control unit reduces a change in a target speed ratio of the continuously variable transmission when a sensitivity coefficient is large as compared to when the sensitivity coefficient is small. When the sensitivity coefficient is large, a change in speed ratio is suppressed, so the stability of the speed ratio is improved. When the sensitivity coefficient is small, the response of a shift is improved. The controller changes a degree of suppressing a shift of the continuously variable transmission in response to the sensitivity coefficient, so it is possible to suppress a shift where necessary. Thus, it is possible to achieve both improvement in the stability of the speed ratio and improvement in the response of a shift in automatic vehicle speed control. This suppresses a feeling of strangeness experienced by a driver.
