Eco driving courses are one of the methods to gain cost savings in transport companies. Road transport drivers equipped with appropriate knowledge of Eco- driving and defensive driving can reduce the costs of fuel consumption even by one third as compared to those involved in their previous driving style. This is the knowledge of a vehicle operation and ability to use driving techniques that leads to fuel consumption reduction. Based on the conducted tests, an analysis of behavior change of drivers who use Eco- driving in road transport systems has been performed. A comparison of the number of drivers’ reactions to road situations allows to determine percentage change in their behavior which leads to fuel-efficient and ecological driving.

The spread of Smartphones and Tablets has led to the birth and the development of a new business: mobile applications on smartphones. Mobile telephonys continuous growth implies a large number of users that can access all applications of online stores. Mobile business is evolving continuously and offers applications that grant many different innovative services and at the same time mobile business offers many opportunities of development for companies and corporations because participating this new sector is becoming more and more required to improve performances and competitiveness. The purpose of this paper is a quantitative analysis of the smartphone application market through a survey of users desires and an analysis of different mobile application features and business models. The results of the survey provide a full representation of the mobile market potential, with a focus on the applications that work on fuel consumption reduction and road safety. In this framework an evaluation of the presented application EcoSmart is carried out. The application estimates users fuel consumption and returns conclusions about his driving style (with focus on fuel consumption). The user can also review offline his paths and the geo-localised driving style data thanks to the Smartphones GPS. The EcoSmart application replaces the OBD device and the consumption data, that can be obtained from the car engine, approximating fuel consumption just based on the dynamic of vehicle motion that is evaluated on GPS data. This procedure is simple and innovative. This study provides a demand survey for this kind of services and a sector analysis. The survey has been carried out using traditional market research methods, with a qualitative approach that is used to understand users habits of purchase and users desires. The second one was realised investigating the applications which are similar to EcoSmart on the Apples Appstore and the Google Play Store, analysing their features and how they can be distributed to the users.

Optimization of gear ratio with the objectives of fuel consumption reduction and vehicle longitudinal performance improvement has been the subject of many studies for years. Finding a strategy for changing gears with specific control objectives, especially in the design of vehicles equipped with Continuously Variable Transition system (CVT), which has advantage of arbitrary selection of gear ratio, has been the aim of some recent researches. Optimal control theory has rarely been used in the previous control approaches applied to such systems due to the limitations in the use of fast computational systems. The aim of this study is to design the aforementioned gear ratio change strategy and related control rules on the basis of optimal control. A driver model is also designed for the simulation of driving cycle using MATLAB Simulink Toolbar. Results of implementing optimal control rules in vehicle longitudinal movement simulation with the aim of fuel consumption reduction are finally represented. The presented method has the remarkable advantage of considerable fuel consumption reduction in comparison to other proposed approaches for gear ratio change strategies.

Establish simulation models of the conventional and parallel hybrid electric back-loading compression sanitation vehicle by AVL CRUISE and MATLAB/Simulink software. Study on control strategy of parallel hybrid electric vehicle based on the work characteristics of back-loading compression sanitation. Results show that: about 24.5% fuel consumption reduction in hybrid modeling compared to the conventional sanitation vehicle under heavy commercial vehicle standard test cycle (C-WTVC, Adapted World Transient Vehicle Cycle), and battery SOC was little changed at 50%. About 32% fuel consumption reduction in hybrid compared to the conventional vehicle under the actual road testing spectrum, and SOC increased about 21.6% relative to the initial state. It controls the engine to work in more stable operation region and reduces engine idle time, but increases engine start-stop times. It also could provide some references for specific engine development of parallel hybrid electric vehicle
