Abstract :
A new concept is introduced to optimize the performance of the entire powertrain: integrated powertrain control (IPC). In this concept, the synergy between engine, driveline and aftertreatment system is exploited by integrated energy and emission management. As a result, fuel efficiency and drivability can be optimized simultaneously within the boundaries set by emission legislation. This is essential to meet both future CO2 targets and ultra low emission limits. As a first step towards IPC, the potential of the proposed approach is demonstrated for a series hybrid diesel passenger car. The studied powertrain is based on a VW 1.2l TDI engine, which is equipped with a urea-based SCR-deNOx aftertreatment system. For three different energy management strategies, chassis dynamometer results are presented over a European NEDC test cycle. Additional simulations demonstrate the potential of integrated energy and emission management, especially during low temperature conditions. Projections show that 130 g/km CO2 and Euro-6 NOx emission targets can be simultaneously met for the studied C-segment vehicle.
