Abstract:
A continuously variable transmission shift control apparatus comprising:a continuously variable transmission provided with an actuator that performs a speed shift operation by an operating fluid supplied to and discharged from the actuator; and a controller adapted to control a speed ratio of the continuously variable transmission so that a rotation speed of an input member of the continuously variable transmission reaches a target input rotation speed, the controller compares a temperature of the operating fluid with a temperature predetermined to determine whether the temperature of the operating fluid is less than a temperature range, and when it is determined that the temperature of the operating fluid is less than the predetermined temperature, the controller sets a setting range of the target input rotation speed to a second setting range that is narrower than a first setting range which is set when the temperature of the operating fluid is within the normal temperature range, and sets the target input rotation speed corresponding to a state of running of the vehicle within the second jetting range.
