Estimating the term…
An electric drive system includes a fuel-driven engine (202) driving an electrical power generator (204) that provides power to one or more electric drive motors (210). A method of load management in the electric drive system includes receiving an actual fuel signal, an engine speed (920) signal, a throttle position signal, a motor speed (712) signal, an intake air pressure, a barometric pressure signal, and an intake air temperature signal. These values are used to determine a torque limit. The torque limit is used to limit a torque command to the electric drive motors (210) such that the torque command is consistent with the operating capabilities of the engine (202).
A computer-readable medium having thereon computer-executable instructions for performing load management within an electric drive system including an engine having an output for driving an electrical power generator, the electrical power generator providing power to one or more electric drive motors, the computer-executable instructions comprising:
