Jaguar-Land Rover launches noise-cancel tech

Published

on

Jaguar Land Rover says it has developed active road noise cancellation technology that can help remove unwanted sound around the cabin area.

It says in a statement that by reducing low-frequency noise exposure, it can help prevent driver fatigue on longer journeys.

Specifically, the automaker says it is pioneering the software that will reduce motion sickness by adapting the driving style of future autonomous vehicles, to continue to provide its customers with the most refined and comfortable ride possible. It notes that there are a myriad of noises that can distract drivers and increase fatigue.

“In order to quell it, Jaguar Land Rover has revealed new noise cancellation technology that removes unwanted road and tyre sounds from the cabin and provides a quieter and more refined experience for drivers and passengers,” it states.

It says the technology, introduced on the new F-Pace, new XF and Range Rover Velar, is capable of lowering unwanted noise peaks by 10dB and overall noise levels by 3-4dB – the equivalent of turning down the in-car sound system by four ‘steps’.

The firm says this significant reduction in exposure to low-frequency noises up to 300Hz can help prevent driver fatigue on longer journeys.

According to theJLR, its aim to make roads safe by reducing accidents and improving driver well-being is a key component of the car company’s journey to Destination Zero: an ambition to make societies safer and healthier and our environments cleaner through relentless innovation.

Explaining how it works, it states that the Active Road Noise Cancellation, enabled by Silentium’s Active Acoustics technology, uses sensors on each wheel to constantly monitor the vibrations from the road surface and calculates the opposite phase sound wave needed to remove the noise heard by the occupants.

It also says the system uses sensors to monitor in real-time, unexpected noises from potholes or rough surfaces can be isolated and removed.

The cancellation sound is said to play through the Meridian sound system, with the vehicle monitoring cabin occupancy to optimise Active Road Noise Cancellation performance for all drivers and passengers.

The JLR says the technology offers a no-compromise solution to balancing refinement, vehicle weight and driving dynamics for a complete premium feel.Active Road Noise Cancellation combines with Engine Noise Cancellation on the updated F-Pace and new Range Rover Velar with the P400e plug-in hybrid (PHEV) powertrain to further enhance the sense of well-being.

Iain Suffield, Jaguar Land Rover Refinement Advanced Technologies Specialist, is quoted as saying, “We are committed to creating a haven for our customers and this new technology allows us to remove unwanted noises from the cabin. It makes the experience more tranquil, improving passenger wellbeing and helping to reduce cognitive load and thus reaction times. This research is all part of the journey to Destination Zero.”

Dr Steve Iley, Jaguar Land Rover Chief Medical Officer, also said, “Active Road Noise Cancellation technology not only has the potential to improve road safety but also well-being and quality of life for our customers.

“In a post-coronavirus world, where a ‘new normal’ is emerging, we expect customer expectations of private transport to change. An extra focus will be placed on safe, clean mobility where personal space, well-being and hygiene carry a premium.”

Tesla driverless car explodes after crashing into tree

Published

on

Two men have died after a Tesla vehicle, which was believed to be operating without anyone in the driver’s seat, crashed into a tree on Saturday night north of Houston, authorities said.

After the fire was extinguished, authorities located two occupants in the vehicle, with one in the front passenger seat and the other in the back seat of the Tesla

The accident came amid growing scrutiny over Tesla’s semi-automated driving system following recent accidents.

The US auto safety agency said in March it had opened 27 investigations into crashes of Tesla vehicles.

“There was no-one in the driver’s seat,” Sergeant Cinthya Umanzor of the Harris County Constable Precinct 4 said.

The 2019 Tesla Model S was travelling at high speed when it failed to negotiate a curve and went off the road, crashing into a tree and bursting into flames, local television station KHOU-TV said.

Tesla and the National Highway Traffic Safety Administration did not immediately respond to a request for comment.

Tesla CEO Elon Musk said in January that he expected huge profits from the company’s full self-driving software, saying he was “highly confident the car will be able to drive itself with reliability in excess of human this year”.

Experts say the self-driving technology must overcome safety and regulatory hurdles to achieve commercial success.

Mercedes-Benz stuns with another seven-seater crossover SUV

Published

on

A few days after Mercedes-Benz revealed what it calls the mother of all electric vehicles in the form of the sophisticated EQS luxury sedan, it has added another stunning product to the Mercedes-EQ family of cars, the EQB.

This is a seven-seater, crossover sport utility vehicle that is to the GLB-class what the EQA is to the GLA.

Car and Driver in a report quotes the premium German automaker as saying the EQB is based on the GLB crossover.

Mercedes-Benz EQ is a series of battery electric vehicles manufactured by Mercedes-Benz. The first model was previewed at the Paris Motor Show in 2016 with the Generation EQ concept vehicle.

The EQB will be launched first in China, where it debuts in a luxuriously equipped all-wheel-drive version with AMG Line styling.

Europe is to have it next in three versions: front- and all-wheel-drive models and a range-optimizing mid-level EQB.

The new vehicle will however not be released to the US market until next year.

While the sheet metal and glass are identical, the styling department under Gorden Wagener has cleaned up the exterior for a more contemporary and sophisticated look.

The front is graced by the trademark EQ headlight/fascia assembly, with a horizontal light bar stretching over the entire width.

This element is reflected on the tail end, which boasts a horizontal light strip as well.

There are EQ-specific colours and wheels, and there will be a choice of regular or AMG-Line front and rear bumpers.

The interior is carried over from the GLB as well, but it comes with EQ-exclusive color and trim options, including rose gold (pictured here), one of Wagener’s favorite colors.

Due to the battery packs in the floor, interior space suffers a bit: Daimler cautions that the third row will only work for people up to 5’5″ and the trunk shrinks considerably.

That said, the EQB is still a crossover SUV that offers more space than usual for its exterior dimensions.

The EQB was unveiled in China, and it will be launched there first as a fully loaded model with a standard AMG Line look, all-wheel drive, and two motors that make a combined 288 horsepower.

Europe will get both the EQB350 4Matic with around 268 horsepower and the front-wheel-drive EQB250 with 221 horsepower; there will also be a mid-level version designed as a long-range model. Both China and Europe will see the EQB at dealers within the 2021 calendar year.

The US will have to wait until 2022, and the company is mum about the possible powertrain options.

Car and Driver says, “What we can deduce from our experience with the EQA is that even the least powerful versions of the EQB will come in at around 4500 pounds, which we hope won’t translate into plodding, cumbersome handling characteristics, even if that would feel a bit less out of place in a people hauler like the EQB than in a compact hatch like the EQA.

“There will be no true AMG version, unlike on the EQS and the EQE. However, we’ll suspend judgment until we can drive it.”

Audi to light up Auto Shanghai with new E-Tron

Published

on

Audi has released a first teaser of its new E-Tron sedan ahead of the launch of the lustrous car today April 19 at the 2021 Auto Shanghai.

But it only showed the long front end, though the company is back with a second teaser that reveals much more for the car.

The latest teaser, posted to Audi’s Weibo account, the Facebook-like Chinese social media site, shows the car in profile with dramatic shadows obscuring most of the bodywork. But a little tweaking in Photoshop reveals a bit more of the car’s styling.

One of the first things jumping out is the rear overhang, which looks oddly elongated compared to the front.

Audi will show off the car at Auto Shanghai 2021 on Monday, April 19.

However, while its reveal is imminent, the new sedan isn’t expected to go on sale until the 2023 model year, so it will be a bit before you can buy one.

It should be the first model to ride on the brand’s Premium Platform Electric architecture that Audi jointly developed with Porsche.

The teaser confirms much of what is expected – a sedan similar in size and shape to the Audi A5 Sportback.

However, the new E-Tron does look sleeker than the A5 Sportback, with a lower greenhouse and unique proportions. One can even spot the charging door on the rear quarter panel.

Elections will power the new fastback sedan, though the setup remains unclear. A single-motor model will power the rear wheels, while a dual-motor setup in higher performance trim will power all four.

It should also sport 800-volt charging and offer around 300 miles of range, though that could be less in the US with its strict testing regiment. Inside, people should expect to see a similar design to what’s in the E-Tron GT, though it will be a bit less luxurious as this new E-Tron will likely slot below the GT.
