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.

摘要： A control system of a power transmission mechanism, in which a transmission torque capacity between transmission members varies according to a pressure to be applied to the transmission members and in which the pressure to be applied to the transmission members is controlled on the basis of such a slip condition between the transmission members as accompanies the lowering of the pressure. The control system comprises: a pressure lowering device for lowering the pressure by a preset value; and a pressure setter for setting the pressure, in case the slip between the transmission members is not detected even by lowering the pressure by a preset value with the pressure lowering device, on the basis of the lowered minimum value of the pressure.
