  • Engine load management for traction vehicles
    Patent number: 8428805
    Abstract: 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).
