Driving cycles are designed based on the principal type of traffic anticipated (local street, major arteries, freeways, interstates, etc.). The cycles considered in the study are the EPA Urban, SAE Urban Fuel Economy, Scott Urban and SAE EV Cycles. Studies made to date projecting future trends in automotive performance indicate that the majority of internal combustion engine vehicles will be able to meet these cycles. The three types of electric vehicles considered are all intended to operate primarily in an urban environment. Specifically, the first electric vehicle considered is an introductory passenger vehicle (weighing approximately 1200 kg) capable of operating on urban streets at speeds up to 72 km/h (45 mph). The second vehicle is a light duty van (weighing 1859 kg) also designed to travel on urban streets at speeds up to 72 km/h. The third vehicle is a fully competitive passenger vehicle (weighing 1200 kg) capable of meeting all the requirements of urban traffic, on urban freeways as well as urban streets. Vehicle test weight, battery weight, rolling resistance, and aerodynamic drag coefvicient/frontal area are selected for the three electric vehicles. Utilizing a computer simulation, cycle tests are run to determine peak acceleration and power requirement through the cycle speed range and energy requirements per kilometer. Following this analysis, two driving cycles are selected.
