Abstract
In a transmission control device, a controller determines failure of one of a variator input side rotation sensor and a variator output side rotation sensor. A hydraulic control circuit and the controller variably control line pressure, and in a case where the failure is determined, fix the line pressure to a predetermined value or more. The hydraulic control circuit and the controller variably control a speed ratio of a variator by a double pressure regulation method, and in a case where the failure is determined, variably control the speed ratio of the variator by a single pressure regulation method.
