Drivers in tropical Asian countries typically use HVAC recirculation mode in their automobiles. This behavior leads to excessive buildup of cabin CO concentration levels. The paper describes the CO buildup in a typical commute in Bangkok, Thailand. Auto manufacturers can potentially take measures to alleviate such high concentration levels. The paper also discusses the diffusion of CO through the vehicle envelope, an area that has never been investigated before.
In this work, an eco-driving rating based on the relation between fuel consumption and average trip speed commonly used in traffic engineering is presented. A car following experiment with a driving simulator was used to make an eco-rating chart. The leading car was used to control average speed of each experiment. To calculate the rating, the resulting driving data was divided into trips. For each trip, low level of fuel consumption was given high score while high level was given low score. Rating was given as average of the trip scores. Actual driving data was then used for the leading car for evaluation of the rating. One of the desirable properties of the rating proposed by this work is consistency regardless of traffic conditions. As suggested by the rating chart, it was found that the proposed eco-rating is consistent in terms of ranking drivers around when average trip speed is around 50-70 km/h.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
