Hydromechanical PTO Power Management for Traction and Implement Balance

The patent consolidates multiple disparate controllers into a single centralized power management controller that manages power distribution to implements, auxiliary devices, and drive axles. This unified controller architecture reduces system complexity and computing resource consumption while maintaining the ability to independently control each component through integrated power flow management based on net available power calculations.

The patent implements dynamic power allocation that continuously adjusts power distribution between implements and traction based on real-time operating conditions and priority settings. The system calculates net available power and dynamically partitions power flow to optimize performance, allowing operators to prioritize either implement power or traction power as needed, rather than using fixed power partitioning ratios.

The patent changes the engine speed management parameter from drive pedal input alone to a comprehensive power management strategy that considers net available power, implement power requirements, and traction power requirements. This allows the engine to operate at optimal speeds for fuel efficiency during steady-state road travel while maintaining the capability for rapid acceleration response when needed, by coordinating engine speed with overall system power demands rather than solely with accelerator pedal position.

The patent implements a coordinated power distribution strategy with feedback mechanisms that monitor total power demands from implements and traction simultaneously. The centralized controller calculates net available power and adjusts power allocation in real-time to prevent engine overload during combined maneuvers, such as when the vehicle is accelerating while implements are operated in tandem. This feedback-based coordination ensures reliable engine operation while maintaining independent control capabilities.
