So far, real driving emissions knowledge involves installing Portable Emissions Measurement Systems (PEMS). As a consequence, large scale campaigns of measurement are not feasible. This paper describes an innovative coupling of Information and Communication Technology (ICT) and physical modeling to turn the driver's smartphone into a virtual sensor of pollutant emissions of his/her vehicle. It consists...
This paper proposes a control strategy for an automotive selective catalytic reduction (SCR) system using a NO x sensor in a feedback loop. As is representative of real world applications, the employed NO x sensor is cross-sensitive to NH 3 , which induces several complexities. In particular the ambiguity of the measurements could be detrimental to the closed loop response,...
A simple distributed parameter model is proposed for a Diesel Oxidation Catalyst (DOC). This model focuses on the propagation of the inlet temperature variations. The inlet-to-outlet temperature transfer function is computed. Its inversion allows to derive an open-loop control law corresponding to finite-time transitions of the outlet temperature. However, this straightforward strategy has some shortcomings...
