A method is provided of boosting power to a continuously variable transmission having a motor. The continuously variable transmission is powered by an engine. The method includes selectively adjusting a power output of the engine above a steady state power output rating of the engine when an acceleration of the motor exceeds an acceleration threshold value.

Continuously variable transmission system with power boost

A method of controlling a continuously variable transmission includes sensing an output speed of a motor, determining an upper speed limit based on the output speed of the motor and a positive torque limit associated with the motor, determining a limited motor speed command based on the lesser of a motor speed command and the upper speed limit, and controlling the motor based on the limited motor speed command.
