Title: SHIFT CONTROL DEVICE
Abstract:
This shift control device is equipped with: an actuator for changing the roller position of a toroidal continuously variable transmission, and adjusting the angle of tilt of a power roller; a tilt angle information generator for generating information about the tilt angle; a position estimator for obtaining an estimated value of the roller position; and a position controller for obtaining an operation command value for the actuator so as to eliminate the deviation between the roller position estimated value and command value. Furthermore, the position estimator is configured so as to obtain the estimated value on the basis of the operation command value and the information about the tilt angle generated by the tilt angle information generator, and correct the estimated value on the basis of environmental parameters which affect the operation of the power roller.
