Hybrid drive system for a combined harvester and traction drive for a combine harvester

摘要

Hybrid drive system for a combine and traction drive for a combine harvester. A hybrid to a combined trigger system including a control is described, wherein the hybrid system control determines a packet load state; battery pack, and the hybrid system control also receives the estimated current engine load and engine speed from the engine control. Depending on these variables, the hybrid control sends a torque command to an engine / generator control to provide a desired mixed engine-generator-speed-torque curve. In cases where the battery pack may be loaded, an engine fuel curve is established by the engine control to provide maximum engine power at isochronous speed, and when the battery pack is fully charged, the engine fuel curve is reduced to be modeled so that battery power assistance is no longer used until engine speed drops
