Development of Gasoline Engine Management Systems control features Tata Consultancy Services in alliance with a leading Tier-1 supplier has developed control and diagnostic features to be implemented for a Gasoline Engine Management System (EMS) that will be used in a passenger car that meets EU4 emission norms. From the high level requirements provided by the Tier-1 , the control features deve...

A novel fast human vision adapted 3D visualization engine is described. In accordance with the human vision peculiarities (asymmetry between left-right and up-down oppositions, dependence of the spatial resolution on the velocity, etc.), we use the cylindrical coordinate system whose axis coincides with the symmetry axis of an observer, and implement the different rendering regimes for moving a...

The increase in fuel price is constraining car manufacturers to produce highly efficient engines with more regulations in terms of pollutant emissions. The increasing complexity of modern engines has rendered the prototyping phase long and expensive. This is where engine modeling becomes in the recent years extremely useful and can be used as an indispensable tool when developing new engine con...

T he major role that computational devices play in cars became dramatically apparent last September, when the Environmental Protection Agency announced the results of its investigation into Volkswagen. The EPA discovered that the German automaker had installed software in some of its diesel-engine cars that controlled a system for reducing the emission of environmentally hostile nitrogen oxides...

Low fuel consumption is one of the greatest merits of the Diesel engine, emission of nitrous oxides, NOx, and particulate matter, PM, are its most prominent disadvantages. For modern passenger car diesel engines, to achieve low fuel consumption targets, i.e. CO2 emissions, and to simultaneously fulfil the ambitious EU6 emissions legislation, a combination of intelligent injection strategies and...

SpeechDat-Car aims to develop a set of speech databases to support training and testing of multilingual speech recognition applications in the car environment. Two types of recordings compose the database. The first type consist of wideband audio signals recorded directly in the car while the second type is composed by GSM signals transmitted from the car and recorded simultaneously in a far-en...

A Cabin Car Communication System (CCCS) has the goal of improving the communication among passengers inside the car. Wind, road and engine noise, the distance between passengers and other factors make difficult the communication inside vehicles. The driver must often look away from the road and passengers move out of normal seating positions. The CCCS makes use of a set of microphones to pick u...

Binaural Transfer Path Analysis (BTPA) was originally developed for assessing the binaural contributions of individual vehicle noise paths. It is a powerful modeling tool enabling engineers to explore noise transfer mechanisms by distinguishing between excitation source strengths and the transfer behavior of individual elements. The method is well-known for powertrain noise analysis, including ...

Engine fault has a high rate in the car. Considering about the distinguishing feature of the engine, Engine Diagnosis Expert System was investigated based on Diagnosis Tree module, Fuzzy Neural Network module, and commix reasoning module. It was researched including Knowledge base and Reasoning machine, and so on. In Diagnosis Tree module, the origin problem was searched in right method. In whi...
