Abstract
A control apparatus for a continuously variable transmission is disclosed. The control apparatus includes a transmission speed sensor which generates an actual velocity signal in response measuring speed of an output shaft of the continuously variable transmission. The control apparatus further includes a first input device, or speed pedal, which is positionable in one of an infinite number of positions and generates a desired velocity signal corresponding to the position of the speed pedal. The control apparatus yet further includes a controller operable to receive the desired velocity signal, receive the actual velocity signal, calculate a commanded acceleration a.sub.c, and generate a commanded velocity V.sub.c based on the desired velocity signal, a jerk value j, and the commanded acceleration a.sub.c. A method of controlling a continuously variable transmission is also disclosed.
