Abstract
A slippage detection system for a continuously variable transmission capable of continuously changing a ratio between a speed of rotation of an input member and a speed of rotation of an output member is provided. The slippage detection system calculates a correlation coefficient relating to the input rotation speed and the output rotation speed, based on a plurality of measurement values of the input rotation speed and a plurality of measurement values of the output rotation speed, and determines slippage of the torque transmitting member in the continuously variable transmission based on the calculated correlation coefficient.
