ABSTRACT:
A continuously variable transmission apparatus includes: an input shaft, an output shaft, a toroidal continuously variable transmission, a gear-type differential unit including a plurality of gears, and a controller. The controller calculates a torque actually passing through the toroidal continuously variable transmission to obtain a deviation of the torque from a target value and adjusts a transmission ratio of the toroidal continuously variable transmission to eliminate the deviation. The controller stops the adjustment of the transmission ratio when the torque is not stable.
