Abstract
A power distribution method for electric vehicle driven by two power sources includes executing a first power distribution law by a vehicle control unit, wherein the first power distribution law sets a distribution ratio according to a vehicle speed of the electric vehicle, a torque demand, and a current gear of a transmission. The powers outputted by first and second motors are adjusted according to the distribution ratio such that the first and second motors can operate at the most efficient operation points to increase the operational efficiency of the electric vehicle driven by two power sources.
