1. A vehicle comprising:
- an engine;
a generator driven by the engine and configured to produce an electrical power output;
a direct current (DC)-to-DC converter configured to;
derive a first DC voltage from the electrical power output, andconvert the first DC voltage to a second DC voltage;
a wheel;
an electric motor configured to;
respond to the second DC voltage, anddrive the wheel based on the second DC voltage; and
a processor configured to control the engine to run at rotational speeds corresponding to operating points in a set of operating points, wherein the operating points correspond to a demanded electrical power output and the rotational speed increases or decreases substantially monotonically as a function of the demanded electrical power output.

Abstract
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.
