Method and apparatus to control a continuously variable transmission

A method for controlling a variator of a continuously variable transmission includes combining, by a controller, a periodically repeating excitation signal and a desired variator speed ratio signal. A variator ratio derivative is determined based upon the desired variator speed ratio signal combined...

Summary:A method for controlling a variator of a continuously variable transmission includes combining, by a controller, a periodically repeating excitation signal and a desired variator speed ratio signal. A variator ratio derivative is determined based upon the desired variator speed ratio signal combined with the excitation signal. A variator control parameter is determined based upon the variator ratio derivative. The variator control parameter is sent to the controller for controlling the variator in response thereto.
