摘要：
A slippage detection system for a continuously variable transmission capable of continuously changing a gear ratio between an input rotation speed of an input member and an output rotation speed of an output member is provided. The slippage detection system compares a difference between an actual gear ratio calculated from measurement values of the input rotation speed and the output rotation speed and a target gear ratio with a predetermined reference value, and determines slippage in the continuously variable transmission when the difference exceeds the reference value at least a predetermined number of times in a predetermined period of time.
