Abstract

TNO Automotive is developing an Integrated Powertrain Control (IPC) concept for powertrain controls that focuses on integration of the engine, aftertreatment and parallel hybrid electric system. One of the first steps is the focus on hybrid assisted Diesel Particulate Filter (DPF) regeneration. For inner-city distribution trucks the legislation on particulate matter is becoming more stringent. This means that diesel particulate filters will be increasingly applied to inner-city distribution trucks. The fact that these trucks often operate at idle- and part-load poses a great challenge to the successful regeneration of the DPF. Based on a simulation study, the capability of hybrid-assisted DPF regeneration is shown, along with the additional requirements placed on the hybrid components.
