Abstract
A work vehicle including an engine, configured to supply power for driving a ground engaging traction device, and a hybrid power system to drive a powertrain. An engine controller is operatively coupled to the engine and is configured to generate a hybrid torque command received by a hybrid powertrain controller operatively coupled to the engine controller. The hybrid powertrain controller is configured to generate an available hybrid torque signal and a desired hybrid torque signal both of which are configured to be received by the engine controller. The engine controller generates an engine command signal configured to command the engine to operate at a commanded engine torque, in response to the available hybrid torque signal and the desired hybrid torque signal.
