A controller for a continuously variable transmission (CVT) mounted in a vehicle. The controller includes a first setting unit for setting a basic speed ratio of the CVT; a second setting unit for setting an adjustment speed ratio of the CVT; and a control unit for controlling the CVT based on the basic speed ratio and adjustment speed ratio. The second setting unit includes an increasing unit for progressively increasing the adjustment speed ratio according to a increase in a target torque interrelated value in a first operating area, and a decreasing unit for progressively decreasing the adjustment speed ratio according to a decrease in the target torque interrelated value in a second operating area. Between the first operating area and the second operating area, the second setting unit maintains the adjustment speed ratio that is set finally.

Controller for continuously variable transmission

There is provided a hybrid car which includes an internal combustion engine; an electric motor disposed coaxially with a rotary shaft of the internal combustion engine; a planetary gear mechanism which is disposed coaxially with the rotary shaft of the internal combustion engine and the rotary shaft of the electric motor, and is comprised of a sun gear, a ring gear, planetary pinions, and a carrier supporting the planetary pinions; a transmission comprising an input shaft to which power is transmitted from said internal combustion engine and said electric motor via said planetary gear mechanism and an output shaft connected to driving wheels; and a rotation restricting device that properly restricts rotation of a rotor of the electric motor.
