A hybrid electric vehicle and method of its control include a parallel hybrid powertrain including an engine, a transmission, a battery system, a first electric motor coupled to the engine by a first clutch between the engine and the first electric motor, a second electric motor coupled to the transmission and to the first electric motor by a second clutch between the first and second electric motors, and a controller configured to control the parallel hybrid powertrain for optimal operation across a plurality of different propulsion and charging modes, including calculating cost values for each of the engine and the first and second electric motors and selecting optimal propulsion and charging modes based on the calculated cost values.
