Intelligent Smart Approach to Design an Automatic Featured Car



Intelligent vehicles enhance the safety and convenience for both the drivers and passengers. An intelligent vehicle uses various intelligent sensing and control algorithms to assess the vehicle’s environment and assist the driver with safe driving. These algorithms include the collision warning system that allows the driver to avoid a collision. Because of the ability to enhance the safety and convenience, intelligent vehicles becomes a crucial research area for the intelligent transportation system Car headlights are among the most efficient safety measures available. Studies have shown that the accident rate is 1.5 to 2 times higher during night-time than in daylight. The general trend in the Westernized world has been a decrease in road casualties, although the impact that road deaths and injuries have on society is still too great technology can be used to make vehicles that allow
a much greater level of vehicle automation to take place. These changes will also mean a much greater interaction between the driver, the road environment, the vehicle, and other vehicles using the transport system.
All the steps taken towards automation of vehicles, reduces the instances of driver error, which is a contributory factor in at least 9 out of every 10 road accidents. Technology supports a driver in different ways and at different times depending on the vehicle or circumstances, and there are many potential interventions to prevent an accident that can be implemented up until the point at which the accident occurs. There are areas of passive safety in which improvements can be made, such as safer vehicle drive system which has automatic headlights and wipers and anti-collision system and vehicle-to-vehicle compatibility. However, progress in this field is expected to slow and any future work about passive safety is likely to be based around enhancing and developing existing technology rather than new design initiatives.

Electric Cars -What is the future ?

Findings by Transportation Research Board Business Office,Washington (USA) show that
Driven by concerns related to climate change and the depletion of fossil fuels, there is a renewed interest in electric cars. Because electric cars are more expensive than fossil fuel cars, have a limited range and battery charging facilities are still limited, the question is to what extent they will penetrate the market. This paper reports on a state choice experiment conducted in the Netherlands to examine the car drivers’ trade off among purchase price, range, fuel cost reduction and the availability of slow and fast battery charging facilities. The results indicate that especially purchase price, range and the availability of fast charging facilities influence electric car purchase. The results further indicate that market shares for the typical electric cars now available on the market probably will remain low and the target of 200,000 electric cars in the Netherlands in 2020 will likely not be met without policy measures. The analysis suggests that providing a purchase subsidy of 5000 euro and realizing fast battery facilities at all fuel stations both can stimulate electric car purchase to about the same extent. However, providing fast charging facilities is a cheaper option and therefore may be considered the more cost-effective policy measure.

Battery Cars cause higher life cycle emissions than gasoline-powered series hybrid cars

In a  recent finding submitted by Christoph Meinrenken of
Columbia University it is said that ;
Battery cars powered by grid electricity promise reduced life cycle
green house gas (GHG) emissions from the automotive sector. Such scenarios
usually point to the much higher emissions from conventional, internal
combus-tion engine cars. However, today's commercially available
series hybrid technology achieves the well known efficiency gains in
electric drive trains (regenerative breaking, lack of gearbox) even if
the electricity is generated onboard, from conventional fuels.
Here, They analyze life cycle GHG emissions for commercially
available, state-of the-art plug-in battery cars (e.g. Nissan Leaf)
and those of commercially available series hybrid cars
(e.g., GM Volt, at same size and performance). Crucially, they
find that series hybrid cars driven on (fossil) gasoline cause fewer
 emissions (126g CO2eq per km) than battery cars driven on current
US grid electricity (142g CO2eq per km). They attribute this novel
finding to the significant incremental emissions from plug-in battery
cars due to losses during grid transmission and battery dis-/charging,
and manufacturing larger batteries.

Ferrari F430 Spider

The F430 Spider joins the F430 as the latest addition to the new generation of Ferrari V8-engined sports cars. The F430 Spider's innovative aerodynamics, honed to generate dynamic air flows to increase down-force and improve cooling, and the F1 gearbox featuring upgraded software, are just two examples of how Ferrari's technological excellence has been transferred from the track to road.
The F430 Spider's all-aluminium bodywork and chassis have also been carefully strengthened, to guarantee both occupant safety and the structural rigidity demanded by a car of such high performance.
Two very robust steel roll-bars are integrated into the windshield structure to guarantee maximum occupant protection. The electric hood is fully automatic and folds away under its own flush-fitting tonneau cover, allowing Ferrari engineers to hone the aerodynamics of the car with the hood down.
