(EN) METHOD FOR SLIP AVOIDANCE IN A BALL PLANETARY TYPE CONTINUOUSLY VARIABLE TRANSMISSION
(ZH) 球行星式无级变速器的滑动避免方法
Abstract
(EN)
Provided herein is a control system for a multiple-mode continuously variable transmission having a ball planetary variator. The control system has a transmission control module configured to receivea plurality of electronic input signals, and to determine a mode of operation from a plurality of control ranges based at least in part on the plurality of electronic input signals. The system also has a dither control module configured to store at least one calibration map, and configured to determine an oscillating change in speed ratio applied to a commanded speed ratio signal during operationof the CVP to manage thermal and mechanical stress on the surface of the ball.
