Abstract
The following paper aims to bring the topics connected testing and emission measurements, together. It provides for the first time an introduction of connected bench testing with the aim to characterize brake particle emissions with a special focus on the impact of regenerative braking.
Such an approach should combine the advantages of a brake dynamometer including an emission testing setup and a HiL setup to allow a simplified and much more precise testing of brake particle emissions under the impact of regen braking.
It is shown, how significant brake rotor temperatures and as a consequence also emissions can be reduced. Especially the positive effect of emission decrease is astonishing—particle number concentration can be lowered by an order of magnitude, particle mass remains on a tenth of the emission level as it is determined for the case without regen braking.
