| Abstract |
The purpose of this report is to examine the current method of determining the shift schedules used during certification and determine if this method is resulting in shift schedules which are representative of those used by typical drivers. The history of the method of determining shift schedules for the certification process is first examined. Then the current trends of shift schedules found in vehicle owner's manuals are determined, since these are the sources of the shift schedules used during certification. Next, the methods of determining shift schedules of other automobile testing organizations are examined, as well as how people are taught to shift in driver's education schools. Finally, data are presented comparing on-the-road shift speeds to those recommended by the manufacturers. Conclusions and recommendations on alternative methods of determining certification shift schedules are presented. |
