Abstract
A hybrid electric powertrain system is provided including a first engine system, a second engine system and an electric motor. During normal driving conditions, a single engine is utilized for providing driving torque to the drive wheels. During periods of operation where increased levels of torque are required, the electric motor is operated temporarily while the second engine is started and brought up to speed to assist the first engine in providing driving torque to the driving wheels of the vehicle.
