<div class="htmlview paragraph">This paper is a report of the findings and insights derived from a continuously variable transmission (CVT) research study. The research objective was to identify relationships between key CVT parameters and the customer perception of CVT performance. Four factors were studied: Ratio Schedule, Shift Speed, Dead Pedal, and Torque Converter Lock. Researchers evaluated the influence of these factors and their interactions on customer perception.</div> <div class="htmlview paragraph">Although one calibration is not significantly better than others, customers preferred three out of sixteen calibrations. DOE analysis shows flat ratio schedule to be statistically significant for Power and Pick-up. Several 2-way interactions are also statistically significant. Although a trade-off study must be completed to identify the best setting for a given vehicle, two calibration methods may be employed for higher customer satisfaction:</div>
