Method and apparatus for adaptive control of hybrid electric vehicle propulsion

摘要

A series type hybrid electric vehicle 10 including a generator set 300, 310 having an internal combustion engine 300 and a generator 310, a battery array 30 and at least one electric motor 50, 60 includes a controller 200 for controlling propulsion of the vehicle 10. The controller 200 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 50, 60, 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 50, 60, 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. A method for adaptively controlling propulsion of a series type hybrid electric vehicle 10 including an internal combustion engine 300 connected to a generator 310, a battery array 30 receiving electric current at least from the generator 310, and at least one electric motor 50, 60 receiving current from the battery array 30 includes generating a first signal having a value indicative of a user demand, generating a second signal having a value proportional to the first signal and indicative of a demand of the at least one electric motor 50, 60, determining if the value of the first signal is larger than the value of the second signal, increasing the value of a command signal to the at least one electric motor 50, 60, if the value of the first signal is not larger than the value of the second signal, and decreasing the value of the command signal, if the value of the first signal is larger than the value of the second signal.
