Abstract

The variation in fuel economy and emissions at the real vehicle driving is influenced by the human driving behavior. In this study, we focused to decrease these variations. The real vehicle driving performance is evaluated by using the chassis dynamometer and the driving-robot. Driver model in this robot was reproduced the intelligent driver behavior. And, this driver model was not necessary to get the powertrain performance (accelerator map) and to adjust any parameters, which operated the driving-robot. We evaluated the driving performance by using the driving index, which will be adopted by WLTP (defined in SAE J2951). The driving-robot with this model was equal the driving performance by human at cold and hot start. So, by using this driving-robot, we can maintain the equity and efficiency at chassis dynamometer test.
