Hyundai develops Road Noise Active Noise Control (RANC)

Hyundai has announced that the company will unveil an upgraded version of its noise reduction system, Active Noise Control (ANC) system. This new technology promises to drastically reduce cabin noise.

Hyundai named the latest technology as the Road Noise Active Noise Control (RANC) system. Though the new technology works on the same principle of emitting inverted sounds of incoming noise, according to Hyundai, the new technology uses sound insulation materials in order to block engine and road noise and this is a shift from the traditional approach.

The company said that ANC is a better alternative than the traditional noise reduction approach because it uses lighter parts such as microphones and controllers which are much more effective. And apart from being effective, they also don’t increase the weight of the vehicle.

Hyundai accepted that in the previous technology, the iteration of the noise control system was limited in its workings. They also said that literally ANC gave results only “when noise was constant and the occurrence of the noise predictable.” Hyundai is considering that the new technology, RANC will be able to process multiple times of noises a lot quicker and cancel them out faster than done by ANC.

RANC uses an accelerator sensor with which, the system calculates the vibration of the road to the car and this is then analyzed by the control computer. RANC takes just 0.002 seconds to analyze. Simultaneously, it produces an inverted soundwave which is generated by the Digital Sound Processor. The microphone constantly monitoring the road noise cancellation status and sends related information to the DSP. This new system cancels noise for the driver’s seat, the passenger seat, and the rear seat separately.

Hyundai stated “RANC is a remarkable technology which takes existing NVH technology to the next level,” said Gangdeok Lee, a Research Fellow of NVH Research Lab, “We will continue to take the leading position of NVH technology and deliver the highest level of quietness to customers.”

Low powered versions with a low battery will also be available, which will consist of a single motor. This will let the Q4 sportsback to release at lower prices.

Although they have just released the concept model, the exterior designer Amar Vaya says that, the product version of Q4 sportsback e-tron will be very similar to this.

The car will have a length of 4.6 meters and height of 1.6m which is just slightly shorter than Ford Mustard Mach E and Model Y which might be potential competitors for Q4 sportsback e-tron. Audi claims that the product version of Q4 sportsback e-tron will hit the markets by late 2020.

This might be one of the best looking Audi vehicle in the market with its aggressive and classy design.

Hyundai Venue to get the clutchless manual transmission

Hyundai has announced that they are introducing a new clutchless manual transmission in their new Venue Compact SUV. It is called the intelligent Manual Transmission or iMT. The engine will be designed with a 120hp, 1.0L, direct injection turbo petrol engine and the company claims that the gearbox will be the first in the market to combine the power of manual and automatic transmissions.

The iMT system is a two-pedal clutch system where the driver can change the gears manually according to his wish without having to use the clutch. The functionality of the clutch pedal is automated.

The system uses an intention sensor, where the gear lever will inform the Transmission Control Unit (TCU) if the driver has any intentions of changing the gear. The TCU, then signals the hydraulic actuator, which will engage and disengage the clutch plate when the driver shifts the gears.

With the iMT/ the two-pedal system, the need to manually operate the clutch is eliminated while the driver gets the full driving experience by being able to shift the gears himself. This will relieve the stress of driving in the city traffics. Hyundai says that the efficiency of the vehicle is improved using iMT without compromising fuel efficiency and performance.

The Hyundai Venue is currently offered with a 6-speed manual and a 7-speed DCT auto box with a small capacity turbo power plant. The 1.0 liter turbo engine with manual transmission is available in S, SX and SX(O) which is priced at 8.46-10.95 Lakhs. The DCT automatic is available in S and SX+ at the rate of 9.60-11.51 lakhs.

The iMT technology might be a game-changer in the market and Hyundai will probably beat its sister company Kia in bringing the technology to Indian markets. Kia had announced that their upcoming Venue fighter, the production version of sonet compact , SUV will debut with an iMT gearbox.

The first modern electric car - EV1 Electric

There are lots of confusion regarding which one is the first electric car in the world and people often come to the conclusion that it might be Tesla or Nissan Leaf. But. According to the latest reports published by Interesting Engineering, the first modern age electric car was launched in 1996 and is the EV1 by General Motors.

The history of electric cars goes back to 200 years even before the launch of the first combustion cars. Professor Sibrandus Stratingh of Netherlands, in 1834 made the first electric car along with his assistant Christopher Becker. The car was basically, a four-wheeled cart with non-rechargeable batteries. In the U.S a chemist, William Morrison from Des Moinus, Lowa made tan electric wagon 1890. It was a 6 passenger vehicle with a top speed of 14 miles per hour.

The British inventor, Robert Anderson developed the first crude electric engine. It was in the late 1800s or the second half of the 19th century that the first useable electric cars came on to the roads.

In 1996, General Motors released the first mass-produced electric cars of the modern era, EV1. It was a two doors subcompact coupe with a drive train. The General Motors EV1 was designed based on the model of the Impact electric concept car which was exhibited by GM in Los Angeles Auto Show in 1990. They received positive responses from the experts for their model and later mass-produced the EV1 vehicle following the same concept. The company stopped the production of this car in 1999.

GM EVI was a 2 door coupe as mentioned earlier, and measured 4310mm in length, 1770 in width. It had a height of 1280mm. The vehicle was not just the first to use electric power in the era but also the first to use Aluminium for chassis. The body panels were made of plastic instead of metals and wheels had magnesium alloys. This reduced the overall weight of the vehicle. The drag coefficient of the vehicle was 0.19 which was very low and made it more efficient.

This electric car had a three-phase AC induction motor and the electric motor could produce 137BHP and a torque of 149nm. The car was front-wheel drive electric vehicle with single-speed reduction transmission system. General Motors had also fitted the car with an Anti break locking system, traction control system, and low rolling resistant tires.

 

Although the EV1 was a technological trendsetter, it was a failure in the commercial market. The demand for the electric vehicle was not as big as that for other vehicles. Therefore, the production of GM EV1 was stopped in 1999 and they ended the project in 2003, the same year that Tesla came into existence. They released their first electric car in 2008 which was powered by Lithium-ion batteries.

The launch of Tesla Model S in 2012 had changed the face electric vehicles and their market.
