The hybrid powertrain includes an internal combustion engine, a regenerative brake/motor and an electric energy storage device such as a battery. Preferably the internal combustion engine is a diesel engine with programmable injection events and programmable intake and exhaust valve events. The regenerative brake/motor is capable of operating as both an electric generator and as an electric motor. The battery receives electric energy from the regenerative brake. In additional to supplying electricity to the motor, the battery drives the engine accessories. The battery also supplies electric energy to keep the exhaust aftertreatment systems (Lean NOx, NOx absorber, PM Filter) at optimal temperature to improve conversion efficiency. A powertrain controller schedules the energy distribution and driving forces associated with both the diesel engine and the motor to maximize the vehicle fuel economy and to minimize the vehicle exhaust emissions.
