A vehicle comprising an engine, a generator driven by the engine and configured to produce an output, a direct current (DC)-to-DC converter configured to derive a first DC voltage from the output, and a convert the first DC voltage to a second DC voltage, a wheel, an electric motor configured to receive the second DC voltage, and for driving a wheel of said vehicle drive the wheel based on the second DC voltage, and a processor configured to control the engine to run at an engine speed corresponding to a first operating point in a set of operating points, wherein the first operating point corresponds to a demanded power.

Method, apparatus, signals and media, for selecting operating conditions of a genset

A method and apparatus for managing power in a hybrid vehicle is disclosed. The vehicle includes an engine, an electric motor, and an energy storage element coupled to the motor. The method involves receiving a request to supply operating power to drive the vehicle and responding to the request by selecting an apportionment of operating power between the engine and the motor from among a plurality of apportionments having respective operating costs such that the selected apportionment is associated with a minimum operating cost, the operating cost including at least an engine fuel consumption cost and a storage element lifetime cost. The method further involves causing power to be supplied by at least one of the engine and the motor in accordance with the selected apportionment.
