In recent years emissions related to transportation
have been in the focus of a lot of research and various legislation
changes. Especially CI engines were found to show substantial
differences between certification values and measured on-road
emission. Motivated by that we study if automated longitudinal
control can help improving emission compliance.
Therefore within this work a fuel optimal longitudinal vehicle
control, which allows emission consideration, is developed. The
potential of optimal vehicle control is investigated, and it is
shown that the sole focus on fuel efficiency is not always
desirable. The method presented relies on information of the
future road grade and considers comfort oriented limits to avoid
unrealistic and uncomfortable trajectories.
A lot of work on optimal vehicle control focuses solely on
fuel efficiency, however we show that not considering emissions
when planing vehicle trajectories can lead to different speed
profiles and undesired excess emissions.
