After obtaining a DC, most authors compare it against other DCs, particularly type-approval DCs, and highlight the observed differences. However, few published works take actions to (i) ensure that the computational algorithm implemented is free of mistakes and (ii) verify that the obtained DC accurately represents the driving pattern of the region and replicates real-world vehicle fuel consumption and emissions when tested on a chassis dynamometer. This chapter outlines methodologies for evaluating the implemented computational algorithm, assessing the DC’s ability to replicate energy consumption and emissions, and considerations for using a DC in specific applications.
