Abstract
Within the scope is a method for detecting the variator slip in continuously variable transmission (CVT transmission). The tribologic slip is detected by monitoring a rotating variator according to vibration and a subsequent evaluation.
Claims14
A method for detection of variator slip in a continuously variable transmission, the method comprising the steps of:
- monitoring a vibration generated by a rotation of the continuously variable transmission;
- and
- determining a tribologic slip of the continuously variable transmission by evaluation of the monitored vibration.
