Abstract:
It has been established that automobile in-cabin air quality can be improved by
controlling the air recirculation. It has been done since 1989 by closing and
opening the flap at the right times to keep high pollution out of the cabin.
This study evaluates in-cabin pollution reduction using flap open/close
strategies based on real-time air quality map information received by the
vehicle. Traffic pollution data was collected from vehicles with on-board air
quality sensors driven for months within a city. This data was used to create
high-resolution pollution maps. Using these maps, a flap open/close algorithm
was designed and applied to a set of recorded trips. The amount of pollution
entering the vehicle cabin was then calculated and compared, with and without
flap control. Results show that the in-cabin pollution reduction achieved with
flap control is significant, even with a limited amount of data collected to
create the maps. It is expected that the maps will gain in predictive value, as
the amount of data collected to calculate them increases. This should in turn
increase the pollution reduction efficiency of the method.
