Texasota Report post Posted December 20, 2014 Continuing with the Hybrid Electric Control Software, the Creep Mode was the first item: Driving ModesThere are five fundamental operating modes in the hybrid electric system: • series mode • electric mode • positive split mode • negative split mode • engine cranking mode Series ModeThe system operates in this mode when the engine is running and the vehicle is not moving. This is the preferred mode whenever the high voltage traction battery is charging, passenger compartment temperature control, high voltage traction battery temperature control or catalyst warm up is necessary.Electric ModeThe system operates in this mode when the vehicle is propelled by the electrical power stored in the high voltage traction battery. The torque is supplied to the output shafts by the traction motor. This is the preferred mode whenever the desired torque is low and can be produced more efficiently by the electrical system than the engine. The electric mode is also used in reverse because the engine can deliver torque only in a forward direction. Come on, GrySql! I'm not going to sleep a wink tonight until I get to read about the remaining three modes. You are a tease. Quote Share this post Link to post Share on other sites
