چکیده
This paper will describe different possible control strategies that can be implemented in hybrid electric drivetrains. A non-exhaustive list will be established of possibilities applicable on series (SHEV), parallel (PHEV) and combined hybrid vehicles (CHEV). Some examples: optimal operating point or line, time deviation limits, location (city or country), State of Charge (SoC) and vehicle speed criteria; minimum APU ON-time, relative power distribution, auxiliary power unit (APU) power in function of traction power, minimum efficiency loss, etc.

A Control Strategy for Mode Transition with Gear Shifting in a Plug-In Hybrid Electric Vehicle
The mode transition from electric propulsion mode to hybrid propulsion mode is important with regard to the power management strategy of plug-in hybrid electric vehicles (PHEVs). This is because mode transitions can occur frequently depending on the power management strategies and driving cycles, and because inadequate mode transitions worsen the fuel efficiency and drivability. A pre-transmiss...
