Abstract
The longitudinal motion characteristics of large sized diesel trucks equipped with the electronic governor, automated mechanical transmission (AMT) and an electronic brake system (EBS) are identified through actual running test and modeled for simulation. The modeled characteristics of engine governor, clutch and brake are given as simple equations. The shift schedule is given by vehicle/engine speed and accelerator %. The model simulates enough actual vehicle motion and indicates used gear region on the governor chart considering the application to the fuel consumption model.
