Tyres influence on vehicle fuel economy

Fuel Economy Sensitivity to Vehicle Mass for Advanced Vehicle Powertrains

In 2002, the U.S. Department of Energy (DOE) launched FreedomCAR, which is a partnership with automakers to advance high-technology research needed to produce practical, affordable advanced vehicles that have the potential to significantly improve fuel economy in the near-term. Advanced materials (including metals, polymers, composites, and intermetallic compounds) can play an important role in...

Vehicle Miles Traveled, Fuel Economy Efficiency And Costs of Corporate Average Fuel Economy Standard

This paper investigates how fuel economy efficiency affects household vehicle mileage traveled and its distribution. Using a detailed micro-level data of National Household Travel Survey 2001 and 2008, we estimated a recursive structural model for joint determination of vehicle fuel efficiency choice and vehicle mileage traveled each year. We further studied the distributional effects on vehicl...

Vehicle cruise: Improved fuel economy by periodic control

-It is shown that time-dependent periodic control can improve the fuel economy of vehicles in cruise. The time-dependent controls considered are relaxed steady-state (RSS) control, quasi-steady-state (QSS) control and quasi-relaxed steady-state (QRSS) control. Examples are given which show that QRSS control may give better performance than either RSS or QSS control. Properties of optimal cost f...

Impact of PCC Pavement Structural Response on Rolling Resistance and Vehicle Fuel Economy

Reduction in vehicle fuel consumption is one of the main benefits considered in technical and economic evaluations of road improvements considering its significance. Surface roughness, texture, and structural response are the main pavement characteristics influencing rolling resistance. This project investigates the increase in vehicle energy consumption caused by the structural response of a c...
