    摘要： A system and method of controlling a continuously variable transmission with variator speed ratio (VSR) closed-loop feedback is provided. The method includes determining a desired VSR based on at least one of the driver and vehicle inputs, determining a motor position adjustment needed to adjust the position of a roller to achieve the desired VSR, driving the motor based on the determined motor position adjustment needed, sensing a transmission output speed as the motor is being driven, determining an actual VSR as the motor is being driven, and providing closed-loop feedback corresponding to any difference between the actual VSR and the desired VSR and driving the motor to eliminate the difference, thereby achieving the desired VSR with improved quick response time and more accurate control.
