Vehicle continuously variable belt transmission component torque friction coupling slip determination procedure analyses effect of changes in slip excitations from drive train rotational imbalance

摘要

A vehicle continuously variable belt transmission component torque friction coupling (18, SS1, 2) slip determination procedure analyses (34) the effect of changes in slip status influencing excitations from a drive train rotational imbalance using the lock in principle and band pass filtering. Independent claims are included for a slip status unit using the procedure.
