Problem. The most effective energy management strategies for hybrid vehicles and electric are optimization-based strategies. These require prior knowledge of the driving cycle, which is not easy to predict. Goal. goal combine Worldwide harmonized light test cycle (WLTC) with short trips on small sections real traffic levels predict fuel consumption vehicles. Methodology. Research methods experi...

Energy efficiency enhancement has become an increasingly important issue for battery electric vehicles. Even if it can be improved in many ways, the driver's driving pattern strongly influences the battery energy consumption of a vehicle. In this paper, eco assist techniques to simply implement an energy-efficient driving assistant system are introduced, including eco guide, eco control and eco...

Plug-in hybrid electric vehicle (PHEV) technology may reduce fuel consumption and tailpipe emissions in many mediumand heavyduty vehicle vocations, including school buses. The true magnitude of these reductions is best assessed by comparative testing over relevant drive cycles. The National Renewable Energy Laboratory (NREL) collected and analyzed real-world school bus drive cycle data, and sel...

Based on the research of traffic flow model, generating Vehicle Hours Travelled (VHT) and weight factors matrix different cities in speed phase by using GIS whole road network data low-frequency dynamic data. Applying weighting to generate a unified - acceleration distribution with chi-square test select candidate short trips, determine cycle duration each developing Chinese Light Duty Driving ...

Published by Context: Publicized sobriety checkpoint programs deter alcohol-impaired driving by stopping drivers systematically to assess their alcohol impairment. Sobriety checkpoints were recommended in 2001 by the Community Preventive Services Task Force for reducing alcohol-impaired driving, based on strong evidence of effectiveness. Since the 2001 review, attention to alcohol-impaired driv...
