Patent ID: 7304445

Claim:
A motorized off road vehicle, comprising: at least one motor; a plurality of electrical energy converters operable to convert energy to electrical energy having a desired electrical characteristic, the plurality of electrical energy converters comprising first and second electrical energy converters having respectively first and second output voltages and first and second output currents; a plurality of energy sources operable to provide energy to the plurality of electrical energy converters, the plurality of energy sources comprising first and second engines corresponding respectively to the first and second electrical energy converters; and a common Direct Current (DC) power bus electrically connecting the plurality of electrical energy converters and the at least one motor and operable to transport electrical energy from the electrical energy converters to the at least one motor, wherein, at a selected time, the relationship between at least one of a current level and a voltage level of the common power bus on the one hand and at least one of the first and second output currents and the first and second output voltages of the first and second electrical energy converters on the other hand determine, at a selected point in time, which of the first and second engines supplies energy to the bus through the corresponding electrical energy converter.
