Using on-board logging devices to study the longer-term impact of an eco-driving course

In this paper the long-term impact of an eco-driving training course is evaluated by monitoring driving behavior and fuel consumption for several months before and after the course. Cars were equipped with an on-board logging device that records the position and speed of the vehicle using GPS tracking as well as real time as electronic engine data extracted from the controller area network. The data includes mileage, number of revolutions per minute, position of the accelerator pedal, and instantaneous fuel consumption. It was gathered over a period of 10 months for 10 drivers during real-life conditions thus enabling an individual drive style analysis. The average fuel consumption four months after the course fell by 5.8%. Most drivers showed an immediate improvement in fuel consumption that was stable over time, but some tended to fall back into their original driving habits.     

国内客车安全技术研究进展

为提高客车安全性,了解目前客车相关安全标准法规的状况及不足,分析了当前先进的国内汽车主动安全新技术,尤其是部分国内客车企业在安全预警系统、基于ABS的拓展技术及协同式智能安全技术等先进主动安全新技术在客车上的研发和应用;针对国内客车被动安全性存在的问题,分析了部分客车企业在全承载技术、正面碰撞及侧翻试验方面的最新进展状况,并简要概述了国内外安全法规对客车被动安全的性能要求和试验方法。对国内客车安全技术研究进展分析有助于制订更加先进、合理的客车技术标准法规,使其进一步促进国内客车安全技术水平的提高。
