METHOD OF CONTROLLING A CONTINUOUSLY-VARIABLE TRACTION CHAIN OF A MOTOR VEHICLE, WHICH IS DESIGNED TO IMPROVE NOISE CHARACTERISTICS

摘要

The method involves determining a functioning mode based on a set of variables having estimated values to control acceleration, speed of vehicle and crank shaft. A value of rotational speed of an output shaft is corrected such that slipping average (L) of a reduction ratio during a period is between negative and positive threshold values in a permanent mode. The average is outside range of threshold value in a temporary mode.
