Abstract
A series type hybrid electric vehicle and method including a generator set having an internal combustion engine and a generator, a battery array and at least one electric motor includes a controller for controlling propulsion of the vehicle. The controller generates a second signal having a value proportional to the value of a first signal, indicative of user demand, and indicative of a demand of the at least one electric motor, determines if the value of the first signal is larger than the value of the second signal, increases the value of a command signal to the at least one electric motor, if the value of the first signal is not larger than the value of the second signal, and decreases the value of the command signal, if the value of the first signal is larger than the value of the second signal.
