Finding a parking slot is a process very stressful for a person who would like to reach a specific place. It could be considered also expensive since it often causes an increasing of traffic with a consequent increase of pollution. In this paper, we present a smart parking system that helps users to reach a free parking slot, in a small area or a city, using context-aware information to help in the...
This paper shows the results of the research work with regard to optimization of test procedures based on systematic analysis of field behavior. The presented approach outlines all important steps of the overall process, the statistical methods and algorithms used with the help of an example from the automotive industry. The example is based on the data gathered during various rides with four different...
Shift quality is the key of automatic transmission research on mining vehicles due to the frequent gear-shifting. A comprehensive dynamic model is built to analyze shifting process of the transmission system. To calibrate and adjust the hydraulic pressure curves of clutches in the model, the experimental data acquired by road test are used in the strategy as the calibrating reference data. Then the...
The main reason of hybrid vehicle fuel saving is superior to the ordinary vehicles is through motor support to optimize the operation of the engine, in order to achieve the purpose of the fuel efficiency and reduce emissions. The traditional optimization method that the baseline is optimization of engine operating point, line, and optimize the operating range to make the engine run in optimal working...
In order to improve vehicle fuel economy, an energy management strategy is designed. The model of a plug-in hybrid electric vehicle (PHEV) with dual clutch is constructed by combining GT-drive and MATLAB/Simulink. Different driving cycles are chose to run the simulation to verify energy management strategy. The results show that the energy management strategy can meet the power demand, and economy...
As worldwide urban populations grow rapidly, higher volumes and more frequent delivery demands create great challenges for all stakeholders in last mile logistics to balance the efficiency of last mile delivery and sustainability of urban environment holistically. We propose a collaborative platform as virtual consolidation center to encourage collaboration among these stakeholders with minimum information...
For evaluating or training different kinds of vision algorithms, a large amount of precise and reliable data is needed. In this paper we present a system to create extended synthetic sequences of traffic environment scenarios, associated with several types of ground truth data. By integrating vehicle dynamics in a configuration tool, and by using path-tracing in an external rendering engine to render...
In this paper, the use of evolutionary metaheuristic for the management of emergency rescue operations applied to real-word scenarios is analyzed. The problem of selecting the best candidate assets for a given emergency event is addressed. While the problem of deploying one single resource is trivial, its complexity grows when considering more assets to be deployed at the same time. Two objective...
To overcome the difficulty on objective measurement of shift comfort of automatic mechanical transmission(AMT) , the feasibility and advantages of using second derivative of the transmission input shaft speed was confirmed to calculate the gear-shifting jerk. The calculation process of jerk was elaborated in more details and jerk nondimensionalization was performed for control necessity. Finally,...
Predictive operational strategies enable fuel savings by optimizing the powertrain operation of a vehicle taking lookahead data like velocity limits and slopes of the planned route into account. Gear changes, free-wheeling, speed and operational modes are optimized along that route to achieve minimal fuel consumption. However, these optimizations assume complete information on the route properties...
Energy efficiency has become a major issue in trade, transportation and environment protection. While the next generation of zero emission propulsion systems still have difficulties in reaching similar travel distances as combustion engine propulsion systems, it is already possible to increase fuel efficiency in regular vehicles by applying a more fuel efficient driving behaviour. An adapted Dynamic...
This manuscript describes a robot interaction for driving assist system of a micro electric vehicle (MEV). A driving assist system has been developed for ordinary car. However, almost driving assist system are one-way communication. We propose an interactive driving support system which a robot is installed in a MEV. As a first step, we propose a driving evaluation system applying a simplified fuzzy...
This article refers to a study on the behavior of an internal combustion engine of a vehicle when you add oxyhydrogen (HHO) as a supplementary fuel, produced from a modified alkaline type electrolyzer, called HHO generator. The first stage consists of a theoretical and experimental analysis of what happens in the internal combustion engine by adding the oxyhydrogen. As a result of this first stage...
It is an important issue to investigate the deterioration state of connectors used in long driven vehicles in order to develop vehicle connectors. There are a few reports that investigated the deterioration state of connectors used in long driven vehicles in detail. Therefore, the deterioration state of a connector collected from a vehicle (driven for 8 years, 100,000km mileage) was investigated through...
The operation of electric vehicles in cold weather is a concern, but the precise nature of the impact on travel range and energy consumption is not well characterized. The Chevrolet Volt, a commercially-available plug-in hybrid electric vehicle (PHEV) was driven-to-depletion across a broad range of temperatures as occur naturally in Winnipeg, Canada, due to its climate. Results conform to a simple...
In order to meet the future fuel economy and Greenhouse gas emission standards, such as the EPA first-ever 2014-2017 Commercial Vehicle regulation, advanced vehicle powertrain concepts have to be introduced to the market. Configurations like hybrid or plug-in hybrid electric vehicle are becoming more accessible and popular due to their perception of efficiency and lower direct environmental impact...
Global climate change, energy independence and sustainability have encouraged automotive sector stakeholders to adopt further technological researches on the integration of Fuel Cell (FC) within Electric Vehicles (EVs). This paper aims at presenting a multi-stack FC configuration inside the EV to minimize its start up, heating/cooling, and cycling problems via proposing a novel thermal management...
This paper results from a governmental founded research project which includes the development, demonstration and evaluation of an innovative power-splitting hybrid drive train. The rear axle is driven electrically; the front axle is driven by a combustion engine (ICE) via a double rotating electric machine which enables a power-splitting operation of the presented hybrid drive train. An Energy-Management-System,...
Automated Manual Transmission based on hydraulic clutch actuation gives high performances and comfort to a recreational vehicle. However, its continuous power consumption is too high to be considered in a hybrid version of a recreational vehicle. Hence, the objective is to evaluate the fuel consumption reduction achieved by the clutch electrification. The method is based on numerical models of energy...
Modern industrial equipments of all kinds are instrumented with a large number of sensors that continuously transmit their readings wirelessly, giving rise to what is often referred to as the ‘industrial internet’. Such data are often explored by engineers to determine the different usage patterns and behavior of similar machines. In this paper we describe a technique to automatically summarize the...
