Proposed Mapping for Duty Cycle Type B During the WVU Dyno Tests, synthetic duty cycle Type A was implemented, and information was generated and collected for that cycle. One of the runs (i.e., run 5259-2; see the Dyno Test Report in Appendix E) is shown graphically in Fig. 49. The information to produce this duty cycle (i.e., vehicle speed as a function of time) was obtained from sensors installed by WVU during the tests. Notice that, although for this particular run the speeds are different from those suggested in Fig. 47, the shape of the duty cycle is similar to the one shown in that figure or in the left half of Fig. 48.
