Utilization of Intelligent Transport Systems Information to Increase Fuel Economy through Engine Control
Today a rich amount of information about location, grade, and traffic speed can be made available to a vehicle. It is proposed to use this information to design a smart engine control strategy using predictive control that will trade off fuel economy versus trip duration, with only minor hardware modifications. The predicted vehicle state and traffic information are used to determine a velocity envelope that a vehicle may take over a given path. A predictive control strategy optimizes the engine torque to trade off fuel consumption and trip time while keeping the vehicle within a time-varying vehicle speed envelope. This paper presents the control design approach and preliminary simulation results. The vehicle parameters used in simulation have been provided by Audi, a premium brand of Volkswagen Group.
