The fuel economy and emissions of the heavy duty hybrid vehicles are measured by the HILS (Hardware In the Loop Simulator) method. Following the reference vehicle speed is the first priority for the driver model of the conventional HILS. And, this driver model is not equal to the real driving behavior by the human. In this study, a new driver model which simulated the driving behavior by the human was created. The fuel economy and emissions of the heavy duty hybrid vehicles were measured by the HILS adopted a new driver model. EGR (Exhaust Gas Recirculation) system which was installed in a new engine complying with the post new long term emission was controlled in conjunction with a driver performance. Thus, the fuel economy and emissions of those vehicles were affected by the driving behavior differences.
