Abstract
A work machine includes an engine power management system. The work machine includes an engine, a hydraulic temperature sensor, and a coolant temperature sensor. The hydraulic temperature sensor is configured to monitor and transmit a hydraulic fluid temperature, and the coolant temperature sensor is configured to monitor and transmit a coolant fluid temperature. The work machine also includes an engine controller and a machine controller. The engine controller includes a processor, and is operatively associated with the engine and the coolant fluid temperature sensor. The machine controller includes a processor, and is operatively associated with the hydraulic fluid temperature sensor and the engine controller. The machine controller is configured to transmit a torque limit command to the engine controller when the hydraulic fluid temperature or the coolant fluid temperature exceeds a predetermined temperature threshold.
