ABSTRACT:
A toroidal continuously-variable transmission shift control apparatus includes a controlling section to control an actual transmission ratio toward a target transmission ratio by producing a control command in one of a forward traveling control mode for a forward vehicle traveling state, and a reverse traveling control mode; and a control modifying section arranged to select one of the forward traveling control mode and the reverse traveling control mode in accordance with a first parameter representing a driver's intention. The control modifying section is configured to detect a change of the vehicle traveling direction in accordance with a second parameter which is the actual transmission ratio, and to modify the shift control of the toroidal continuously-variable transmission so as to shift the actual transmission ratio to a speed decreasing side upon detection of the change of the vehicle traveling direction.
