2. Predictive Control of Hybrid Electric Vehicles on Prescribed Routes
Abstract : At the highest level in the powertrain control system in a hybrid electric vehicle an energy management controller interprets the driver’s pedal actions as a torque that is to be delivered at the powertrain output. The energy management controller distributes this torque between the engine and the electric machines and decides when to change gear and when to turn off the engine for pure electric propulsion.
