  1. 1. Recent Trends in Automobile Engg. BY: sham
  2. 2. Google Driverless Cars  On the onset of winter break, on December 23, Google announced its first fully functional driverless car, which is ready for testing on public roads. Prior to this, the Internet giant developed various prototypes that lacked on different fundamental and functional aspect. The latest prototype has all the important elements like headlights, steering and brakes. The company have also created a self-driving system with sensors and computers that can be fitted to SUVs like Lexus. This new technology will not only be a breakthrough in tough traffic congestion but sensing technology can also increase road safety. Countries such as the UK and US are working on laws to allow driverless cars.
  3. 3. Automated Manual Transmission (AMT)  In the 2014 Delhi Auto Expo, where more than 70 vehicles were launched, one that pundits hailed as the most important was Maruti Suzuki's Celerio, the first affordable mass segment gearless hatchback. Celerio comes with AMT (automate manual transmission) sourced from Magneti Marelli, component arm of Fiat. AMT is an electro- hydraulic mechanism for automating manual transmission, which derives from Formula 1. It has a hydraulic system and an electronic system. The electronic transmission control unit helps in engaging and disengaging the clutch and gear through an electronic actuator. It also has a sports mode, which enables drivers to move to the manual shifting of gear to increase and decrease the gear ratios with plus and minus either through gear knob /joystick or the steering. In India, AMT is currently available in three cars — Celerio, Alto K10 and Tata Zest.
  4. 4. V2V Communications  In February, US National Highway Traffic Safety Administration announced that it will begin taking steps to enable vehicle-to-vehicle (V2V) communication technology for light vehicles. This technology would allow vehicles to "talk" to each other and ultimately avoid many crashes altogether by exchanging basic safety data, such as speed and position, ten times per second, to improve safety. It uses 'ad hoc network', where every car is free to associate with any other car available in the network and share equal status. V2V, which is also known as VANET (vehicular ad hoc network), is a variation of MANET (mobile ad hoc network). Many automobile manufacturers including are BMW, Audi, Honda, General Motors, Volvo and Daimler working and developing this technology to improve safety, overcome blind spots and avoid accidents.
  5. 5. Pre-Collision Technology  Top carmakers such as Ford and Hyundai have developed a pre-collision assist and pedestrian detection technology. Besides helping the driver detect blind spots, this technology also alerts the driver when he/she is not paying attention on the road. And if the driver falls asleep and does not respond to the warning, then the system applies the brakes on its own. The driver assist system has two types of sensors. One is millimetre-wave radar located inside the front grille, and the other is a monocular camera mounted on the upper, inside part of the windshield. Its collision mitigation braking system delivers an audio and visual warning when there is a risk of a head-on collision. If the driver fails to react, the car will automatically begin breaking itself to prevent or reduce the severity of a crash. This technology will debut in 2015 with Ford Mondeo in Europe. Hyundai would introduce it in 2015 .
  6. 6. Smart Cars  After smartphones, we will soon have smart cars around. In June 2014, Google launched its 'Android Auto', a telematics software that can be connected to car dash board for infotainment. It also enables the driver to access GPS, maps, streaming music, weather, and a host of other applications. A slew of carmakers including Abarth, Acura, Alfa Romeo, Audi, Bentley, Chevrolet, Chrysler, Dodge, Fiat, Ford, Infiniti, Jeep, Kia, Maserati and Volvo will offer Android Auto i . Earlier, at the Geneva Motor Show in March, Apple announced its 'CarPlay' software, which allows devices running on the iOS operating system to function with built-in display units of automobile dashboards. Carmakers like BMW, Daimler, JLR, Honda and Hyundai have installed it in their cars. Infotainment manufacturers like Pioneer & Alpine too have shown interest in Carplay from Apple.
  7. 7. Ford Aluminium Truck  In 2014, Ford unveiled the first aluminium-bodied full-size pickup, rolling out aluminium version of its popular F-150 from its Dearborn plant. It is 700 pounds or about 318 kg lighter than the steel-bodied version, making it a more fuel- efficient and nimbler pickup. The F-150 has been the best-selling vehicle in the US for 32 straight years. Last year, Ford sold nearly 100,000 more full-size pickups than General Motors. Aluminium isn't new to the auto industry, but this is the first time it will cover the entire body of such a high-volume vehicle.
  8. 8. Start- Stop Technology  Start- Stop Technology Hero MotoCorp introduced its first bike with start-stop technology, Splendor iSmart, in March 2014. The company calls it i3s technology which is also known as Idle Start and Stop System. i3s is a green technology that automatically shuts the engine when idling and turns it on, when needed, with a simple press of the clutch, giving more mileage in congested cities.
  9. 9. Land Rover's Invisible Car  In April, Tata -owned JLR introduced a new technology to give drivers a digital vision of the terrain ahead by making the front of the car 'virtually' invisible. The technology — named Transparent Bonnet — enables a driver climbing a steep incline or manoeuvring in a confined space to see an augmented reality view capturing not only the terrain in front of the car but also the angle and position of the front wheels. The cameras located in the vehicle's grille capture data used to feed a head-up display, effectively creating a 'see-through' view of the terrain through the bonnet and engine bay, breaking new ground in visual driver assistance.
  10. 10.  A supercharger: is an air compressor that increases the pressure or density of air supplied to an internal combustion engine. This gives each intake cycle of the enginemore oxygen, letting it burn more fuel and do more work, thus increasing power.
  11. 11.  A turbocharger is a device driven by exhaust gases that increases engine power by pumping air into the combustion chambers. Combustion is limited not by the amount of fuel that can be injected but by the amount of air an engine can gulp in to mix with that fuel.
  12. 12. Air Bag Safty  An airbag is a vehicle safety device. It is a type of occupant restraint system that consists of a flexible fabric bag, also known as an airbag cushion. The airbag module is designed to inflate rapidly then quickly deflate during a collision or impact with another object or a sudden deceleration. The purpose of the airbag is to provide occupant protection and restraint during a crash event. The airbag provides an energy absorbing surface between the vehicle's occupant and a steering wheel, instrumental panel, A-B- C- structural body frame pillars, headliner and windshield/windscreen.
  13. 13. Tubeless tires or tyres  Tubeless tires or tyres: (are pneumatic tires that do not require a separate inner tube.Unlike traditional pneumatic tires which use a separate inner tube, tubeless tires have continuous ribs molded integrally into the bead of the tire so that they are forced by the pressure of the air inside the tire to seal with the flanges of the metal rim of the wheel.
  14. 14. Parking sensors  Parking sensors are proximity sensors for road vehicles designed to alert the driver to obstacles while parking. These systems, which use either electromagnetic or ultrasonic sensors
  15. 15. Anti-lock braking system (ABS)  Anti-lock braking system (ABS) is an automobile safety system that allows the wheels on a motor vehicle to maintain tractive contact with the road surface according to driver inputs while braking, preventing the wheels from locking up (ceasing rotation) and avoiding uncontrolled skidding.
  16. 16. Night vision with pedestrian detection  An automotive night vision system uses a thermographic camera to increase a driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights. Such systems are offered as optional equipment on certain premium vehicles. Night Vision Assistant was introduced in 2010 on the Audi A8. It uses a thermal imaging camera behind the four rings at the front of the car which can "see" 300 meters (984 ft) ahead. The display in the instrument cluster highlights humans with yellow markings.
  17. 17. Flying car AeroMobil is a flying car that perfectly makes use of existing infrastructure created for automobiles and planes, and opens doors to real door-to-door travel. As a car it fits into any standard parking space, uses regular gasoline, and can be used in road traffic just like any other car. As a plane it can use any airport in the world, but can also take off and land using any grass strip or paved surface just a few hundred meters long.
  18. 18. continuously variable transmission (CVT)  A continuously variable transmission (CVT) (also known as a single-speed transmission, stepless transmission, variable pulley transmission, or, in case of motorcycles, a twist-and-go) is an automatic transmission that can change seamlessly through an indefinite number of effective gear ratios between maximum and minimum values.
