Title: METHOD FOR CONTROL OF A BALL PLANETARY TYPE CONTINUOUSLY VARIABLE TRANSMISSION TO EXTEND CYLINDER CUTOFF TIME
Abstract:
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 receive a 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 transmission control module includes a CVP control module. The CVP control module is adapted to implement a cylinder deactivation control process. The cylinder deactivation control process is configured to generate and select a commanded CVP speed ratio and a commanded engine torque based on a desired NVH standard and minimum BSFC.
