RECENT TRENDS IN AUTOMOBILES
Major Technological Trends
1. Green Engine and Alternate Fuels The desire to lessen environmental impacts and reduce oil dependence is spurring interest in alternative fuels and green technologies. The developments include electric cars, hybrid cars, air powered cars etc.
Green Technology & Alternative Fuels
Hybrids use two or more power systems, such as a gasoline engine and an electric drive motor, to provide more efficient propulsion. Learn more about hybrids and what distinguishes them from other vehicles in Green Car’s section on hybrids
Electric cars use one or more electric drive motors, powered by batteries, for zero-emission motoring. Electric cars are recharged by plugging into the grid
Ethanol is an alcohol-based alternative fuel made from biomass. As a popular alternative fuel, ethanol is typically used in the form of E85 to power flex fuel cars outfitted specifically to run on this blend of 85% ethanol and 15% gasoline. Most ethanol today is produced from corn or sugar cane, although this will change as cheaper cellulosic ethanol made from fast growing woody grasses and other biomass becomes a reality
Hydrogen cars are among the cleanest cars on the road, emitting oxygen and water vapor only. Hydrogen is the cleanest burning of all liquid and gaseous alternative fuels
Natural gas is a clean-burning alternative fossil fuel that can easily power internal combustion engine vehicles. The domestic abundance of natural gas makes it a highly attractive alternative fuel option
As a leading alternative fuel, biodiesel can be made from various sources including soybeans and biomass. Biodiesel can be used in most diesel powered cars without modification
Air powered cars are relatively new to the green car scene. Compressed air is currently being explored as a viable 'alternative fuel' to efficiently power car engines with little or no environmental impact
Within each of these segments, several new applications are emerging. For example, in the infotainment segment, navigation systems are popular with new cars. In the driver assistance segment, lane departure warning systems are assisting with driver safety. Several of these applications originated from the consumer market and are now used in automotive applications.
Recent Developments in Auto mobiles – SAFETY
* An automotive night vision system is a driver assistance system to increase a vehicle driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. They are currently offered as optional equipment on certain premium vehicles.
* Adaptive Highbeam Assist is a new headlamp technology introduced in the new generation Mercedes-Benz e-class in spring 2009 which automatically and continuously adapts
the headlamp range to the distance of vehicles ahead or which are oncoming. It practically eliminates the difference between high and low beam, fusing them into one continuous adapting beam. Unlike conventional automatic headlight dimmers which simply switch between high beam and low beam, the new system continually adjusts the beam so that the headlamp cone falls just in front of other vehicles, at the same time always ensuring maximum possible range without dazzling other road users.
* Parking sensors are a technology that allows the driver of an automobile, truck, or commercial vehicle to be alerted to nearby objects in their path. Parking sensors are also known as backup sensors, parking sonar or just sonar
* Intelligent Parking Assist System (IPAS), also known as the Advanced Parking Guidance System(APGS) for Lexus models in the United States, is an automatic parking system
* Electronic stability control (ESC) is a computerized technology that improves the safety of a vehicle's stability by detecting and minimizing skids. When ESC detects loss of steering control, ESC automatically applies the brakes to help "steer" the vehicle where the driver intends to go
* A smart car is an automobile with artificial intelligence (or known as "AI") functionality. As automation technology has progressed, especially in the decades after the invention of the integrated circuit, more and more functions have been added to automobiles
Cars in the future will evolve to run cleaner and faster than ever before, because technologies are being continuously developed by automakers, engine manufacturers, and component suppliers. While more mainstream technologies like hybrid cars and hydrogen fuel cells continue to push the edges of today’s car technology, all new innovations will be introduced in the future, which also contribute to better fuel economy, lower greenhouse gases and improved tailpipe emissions. The various features under study are:
* New Technology has also developed a second system that can generate electricity from moving trucks, buses, and other large load-bearing vehicles
