Abstract:
A method for adaptively controlling propulsion of a series type hybrid electric vehicle including an internal combustion engine connected to a generator, a battery array receiving electric current at least from the generator, and at least one electric motor receiving current from the battery array, comprising:generating a first signal having a value indicative of an accelerator command to a controller; generating a second signal having a value proportional to the first signal and indicative of a demand of the at least one electric motor from the controller to a motor controller; determining if the value of the first signal is smaller than the value of the second signal; increasing the value of a command signal to the at least one electric motor, if the value of the first signal is not smaller than the value of the second signal; and decreasing the value of the command signal, if the value of the first signal is smaller than the value of the second signal.
