Driving Cycles have been an integral part of emission tests and Virtual simulations since a few decades. A Driving Cycle is a representation of running behavior of a typical vehicle, involving the driving pattern, road characteristics and traffic characteristics. Driving cycles are typically used to assess vehicle performance parameters, system sizing & accelerated testing on a test bed or a Virtual test environment, hence reducing the expenses on road tests. This study is an attempt to design a relatively robust process to generate a Real World Driving Cycle. It is based on a Six Sigma design approach which utilizes data acquired from Real world road trials. It explicitly describes the process of generating a Drive Cycle which closely represents the Real World road driving scenario. The study also throws light on validation of the process by simulation and statistical analysis.
