Towards Integrated Powertrain Control: exploiting synergy between a diesel hybrid and aftertreatment system in a distribution truck
conference paper
With the increasing demands on driveability, fuel efficiency and emissions, it becomes essential to optimize the overall performance of future powertrains. Therefore, a system approach is required. In this study, the Integrated Powertrain Control concept is presented, which exploits the synergy between engine, driveline and aftertreatment system. To illustrate the benefits of this concept, the combination of a diesel engine, hybrid driveline and DPF system is studied for a distribution truck. Focus is on minimizing the required energy and components for DPF regeneration. For electric DPF heating, electric heating for DOC light off, and idle-stop cases, the impact on fuel consumption and on DPF temperature are determined during DPF regeneration. It is shown that the operating envelop of the DPF can be extended, even to idle.
