  • Efficiency-based engine, powertrain and vehicle control
    Patent number: 6671603
    Abstract: A method is provided for controlling power units of a vehicle powertrain for optimizing their respective efficiencies, thereby optimizing an overall vehicle efficiency. The method includes the steps of determining an efficiency of a power unit, determining present operational data of the power unit, determining a torque to be provided to the vehicle powertrain, determining a plurality of optimization constraints as a function of the torque to be provided, the present operational data and the efficiency of the power unit, determining an optimized operation mode of the power unit as a function of the optimization constraints and the present operational data of the power unit, and manipulating the power unit to operate in the optimized operation mode.
