THE ADVANCED COCKPIT
The survey carried in June that showed most American automobile buyers was not a wind noise or inadequate acceleration. Drivers today expect vehicles to be advancing in technology, and the automakers are making their driving experience together with it. At the moment the companies have problem of keeping up with the advances. As the apple company comes up with new model of iphone the General Motors also needs to finalize hardware and software in time before their cars reach their market. The automakers will soon emulate the software engineers who write the Smartphone application as they improve their cars. Now you can be able to connect you smart phone using the USB-cable to your car dash board, load your contacts and music. According to engineer David bloom of the BMW group, he considers a Smartphone as free powerful computer customer is bring to the car which will revolutionize you cockpit from navigation screen, gauges and voice commands just as Smartphone this days.
Engineers began to think a way automobiles can communicate with the drivers this is to prevent digital technology from becoming a distraction, for example, Early this year Audi exhibited a system that conveys data about the terrain that could be used in cars. The Cadillac XTS sedan 2013 model sends data to their drivers using tactile feedback from the seat to warn the drivers of dangers. Like movement through blind spots. The Carnegie Mellon University designed a steering wheel that only uses vibration to transmit instructions. As the car reaches turning point, the frequency of 20 tiny buzz increases in clockwise or counterclockwise pattern, thus drivers know which way to turn to.
THE CARBON FIBER
With only two third weight of steel yet 5 times stronger the CFRP is the choice material in making of the racecars. However it is uneconomical for passenger vehicle because of its time consuming and labor intensive manufacturing process. BMW will start selling i3 electric car the following year made with carbon fiber chassis. The four-seat weighs 50% less that of a steel structure. BMW joint enterprise has invested around 100 million dollars in Washington State factory that manufactures carbon fiber bundles of 50,000 carbon fiber filaments. The i3 carbon fiber chassis saves enough weight that offset the mass of the car’s lithium-ion battery pack. The car reaches 100 miles of driving range using smaller, cheap battery than their competitors. The automaker plan is to begin building 1 million or more carbon fiber structural parts yearly by the following year. According to the M.D. BMW Washington Mr. Joerg Pohlman the carbon fiber still costs more than aluminum but BMW can cut the costs to par with aluminum once it starts building cars large quantity. This could make car faster, efficient and more crash resistant.
BEAUTY OF ULTRA-CAPACITORS
Acceleration an electric car reduces the driving cars battery miles but smooth and slow drive the range of drive increases thus perfect battery predictability range. However pairing the batteries with ultra capacitors you could fix that. Ultra-capacitors store charges in electromagnetic field between the two electrodes coated in a porous active carbon allowing them to capture more electricity as fast as an outlet can discharge. This is translated to fast recharge and powerful acceleration.
Today the best ultra-capacitors hold only about 5% as much energy compared to a sized lithium-ion battery this is not enough to power an electric car but it surely helps. A professor in department of electrical engineering at MIT, researching on ways to use nano-tubes to improve ultra-capacitors, says hybrid is the best solution where battery is advanced to store the total energy, while the ultra-capacitor takes care of the peak power demands during acceleration. This could solve the problem of long recharging time of empty electric vehicle to less than 30 minutes. The Ultra-capacitors captures full charge in matter of minutes, enabling faster charging of empty batteries.
Today highly advanced cars correct you when you steer out of lane, brake automatically preventing knocking other vehicle and also determine when you are almost falling asleep. For this network of autonomous cars to work, vehicles must communicate with each other. In May the European Union members funded project called SARTRE that dispatched a trail consisting of tractor trailer being followed by 3 Volvo vehicles on a highway in Spain. The vehicles were separated by 20 feet, all traveling at 50 miles an hour with only one driver driving the This is the 1st real world test of trail of cars autonomous that followed human operated lead vehicle. This trailer of vehicles can be passenger cars on long journey. Thus if the wind resistance is dealt with, this convoys could reduce fuel consumption and reduce tail-pipe emissions by 20% .This in turn can make road trips more pleasant.
THE INTERNAL COMBUSTION
Car manufacturers are including turbocharger and computer controlled direct injection to engines since fuel economy standard is set to increase to 54.5 mpg by year 2025. For example, 2012 BMW 328i runs on turbocharged four-cylinder engine that produces more torque compared to the six-cylinder when replaced. However, turbochargers and direct injection can not do much thus engineers have to think of internal combustion. Scuderi Group in Massachusetts is testing engines that devote separate pistons to compression and power strokes, hence sets motion in series of changes that improves mileage by 50%. The EcoMotors Michigan based firm is perfecting an opposed cycle engine that allows a pair of pistons moving horizontally to share combustion chamber. This added efficiency can push compact car to 100 mpg.
