With advancements in the development of the automated driving technology, vehicles equipped with such technology can be observed widely in market. However, there is a lack of clarity regarding fuel consumption and emission characteristics with automated driving functions. In fact, it cannot be found that any technical papers that have conducted such an evaluation.
Therefore, in this study, it was investigated that an evaluation method to understand fuel consumption and emission characteristics by using the adaptive cruise control (ACC) function. The function is one of the automated driving functions which is widely used and corresponds to Level 2 defined by SAE International (Society of Automotive Engineers). In the approach taken for this study, two vehicles were used as the real driving emission test and the preceding vehicle—equipped with a driving robot—was driven accurately to trace the speed pattern defined by the test cycle. The trailing vehicle was driven using the ACC function, and various performance information of the vehicle was acquired. As the result, it was found that various vehicle performance information with the ACC function was evaluated accurately and the usefulness of the method taken for this study was confirmed experimentally.
