“…From the reasons given above, it can therefore be assumed that the emission factor is nearly independent of the driving speed. This statement is supported by the findings of Beji et al [34], Feißel et al [21] and Tonegawa and Sasaki [35].…”

“…It is therefore the higher driving force in the tire-road contact that leads to higher PM emissions, not the speed itself. Feißel et al also draw this conclusion from their mobile on-board measurements [21]. Accordingly, this effect is not necessarily visible on the test bench, as there is no air resistance.…”

“…Last but not least, when conducting open-road tests, it is important to note that driving resistance and the driving force required to overcome it increase with driving speed. Possible increases in emissions with increasing driving speed are therefore due to the increased driving force and not to the driving speed itself [21].…”

As fleet electrification progresses, vehicles are continuously becoming heavier, while the used electric motors, with their high torques, enable longitudinal dynamics to be maintained or even increased. This raises the question of what effect electric vehicles have on the emission of tire–road particulate matter (PM). To answer this question, investigations were carried out in this study on a tire internal drum test bench with real road surfaces. In addition to the vertical load, the tire inflation pressure and the driving speed were varied. PM emissions were recorded in real time, resulting in emission factors (emission per kilometer driven) for different load conditions. This allows statements to be made about both the effect on the total emission and on the particle size distribution. It was shown that the PM emission increases linearly with the vertical load at constant longitudinal dynamics. If the tire inflation pressure is increased, the emission also increases linearly, and the increases in emission are equally large for both influences. A clear influence of the driving speed on the emission factor could not be determined. With regard to the particle size distribution, the following correlations were found: higher vertical load and higher tire inflation pressure result in a larger mean particle diameter, while a higher driving speed reduces it. Thus, this study contributes to a better understanding of the expected changes in tire-road PM emissions as a result of electrification.

“…The model was applied for the investigation of wear loss [9]. Feißel et al presented an approach for the estimation of air-borne TRWP emissions as a function of lateral and longitudinal acceleration as well as vehicle velocity [10]. As it can be seen from this review, several approaches for modeling and prediction of exhaust, brake and tire emissions already exist.…”

As a result of rising environmental awareness, vehicle-related emissions such as particulate matter are subject to increasing criticism. The air pollution in urban areas is especially linked to health risks. The connection between vehicle-related particle emissions and ambient air quality is highly complex. Therefore, a methodology is presented to evaluate the influence of different vehicle-related sources such as exhaust particles, brake wear and tire and road wear particles (TRWP) on ambient particulate matter (PM). In a first step, particle measurements were conducted based on field trials with an instrumented vehicle to determine the main influence parameters for each emission source. Afterwards, a simplified approach for a qualitative prediction of vehicle-related particle emissions is derived. In a next step, a virtual inner-city scenario is set up. This includes a vehicle simulation environment for predicting the local emission hot spots as well as a computational fluid dynamics model (CFD) to account for particle dispersion in the environment. This methodology allows for the investigation of emissions pathways from the point of generation up to the point of their emission potential.
