Fuel Economy and Naturalistic Driving for Passenger Road Vehicles

The state-of-the-art eco-driving techniques does not take into account the naturalistic behaviour of human drivers. Therefore, in this paper, a unified driver model is proposed which describes the driver preference during car following and cornering cases. The model is formulated based on the optimal control theory. The fuel consumption model of a traditional vehicle with an internal combustion (IC) engine and CVT transmission is combined with the driver model. The proposed optimal controller is designed to generate speed profile and powertrain inputs, which give a compromise between the driver preference and fuel economy. The simulation results demonstrate that eco-friendly speed profile and optimal powertrain input trajectories could be selected which has good fuel economy and matches the driver desires.
