Whilst driving is inherently a safety critical task, awareness of fuel efficient driving techniques has gained popularity in both the public and commercial domains. Green driving, whether motivated by financial or environmental savings, has the potential to reduce the production of greenhouse gases by a significant amount. This paper focusses on the interaction between the driver and their vehicle -what type of eco driving information is easy to use and learn whilst not compromising safety. A simulator study evaluated both visual and haptic eco driving feedback systems in the context of hill driving. The ability of drivers to accurately follow the advice, as well as their propensity to prioritise it over safe driving was investigated. We found that any type of eco driving advice improved performance and whilst continuous real time visual feedback proved to be the most effective, this modality obviously reduces attention to the forward view and increases subjective workload. On the other hand, the haptic force system had little effect on reported workload, but was less effective that the visual system. A compromise may be a hybrid system that adapts to drivers' performance on an on going basis.

“…Also, this manner of driving reduces CO2 emissions by 6 -10% [13] and fuel consumption in buses by 2% in the 12 months following training [14] 4.35% in the two-month follow-up period [15]. The mean change in fuel consumption for all drivers in the study after their eco-driving course was a reduction of 5.8%, but with large differences between individuals [16].…”

Abstract. In Poland, as in the rest of Europe, air quality depends primarily on emissions from municipal, domestic and road transport sources. The problems of appropriate air quality are especially important within urban areas due to numerous sources of emissions being concentrated in relatively small spaces in both large cities and small/medium-sized towns. Due to the steadily increasing share of urban population in the overall number of population, the issue of providing clean air will over the years become a more significant problem for human health, and therefore a stronger incentive to intensify research. The key challenge faced by a modern society is, therefore, to limit harmful substance emissions in order to minimise the contribution of transport to pollution and health hazards. Increasingly stringent emission standards are being imposed on car manufacturers; on the other hand, scant regard is paid to the issue of drivers, i.e. how they can help reduce emissions and protect their life and health by applying eco-driving rules.

“…The Republic of Korea has revised the fuel economy regulations and fuel efficiency standards to promote the improvement of vehicle fuel economy [2] . Eco-driving technology has attracted much interest through its potential of 10%~15% oil saving [3] . Although the gliding in neutral or gear can save fuel, which kind is more fuel-efficient has caused a lot of controversy which is disadvantage of standardizing the eco-driving and restricts the improvement of fuel economy.…”

Abstract. In this paper, the study was based on the vehicle drive cycle of pulse and glide (PnG), the conversion between the kinetic energy of the vehicle and the sliding resistance power was imported. The ideal state was proposed, in which the combustion energy of the fuel is converted into the kinetic energy of the accelerating vehicle. It was derived and calculated that the efficiency of gliding in neutral is better than gliding in gear under the vehicle with the same initial sliding velocity. The kinetic energy's transformation had been analyzed under different gliding conditions, then the strategy of economic driving is shown: gliding with gear is suggested during the vehicle travelling downhill, which plays "engine brake" and saves fuel; pulse and glide in neutral is encouraged during the vehicle automatically cruise, it makes full use of the inertia of the vehicle to improve the fuel efficiency. Gilding in neutral could be adopted when the predictable distance is long or the travelling speed is low, gilding in gear could be adopted when the predictable distance is short or the travelling speed is high, so that making use of the gliding resistance, instead of unnecessary braking, reduces the speed of the vehicle to enhance the fuel economy. The dispute has been solved which is more fuel-efficient between sliding in neutral and sliding in gear, it will provide a new base in theory for making the strategy of gliding in eco-driving.
