Continental and Sennheiser create an immersive vehicle sound system without speakers

New technology shown at CES allows for automakers to say goodbye to speakers inside their vehicles.

Premium audio systems have what, like 12, 15 speakers? More? Contentnail and Sennheiser teamed up to create a concept car at CES that immerses its occupants in a sound cocoon without using a single speaker.

What?! How does that work?! The technology merges Sennheiser's AMBEO 3D audio technology with Continental's Ac2ated Sound system. The Continental system eschews speakers and instead uses surfaces within a vehicle to produce sound. When this technology is combined with Sennheiser's AMBEO Mobility, the result is "a breathtaking 3D sound reproduction that envelops passengers in an incredibly detailed and vivid soundscape and lets them enjoy their in-car entertainment to the fullest," according to a release.

The weight savings is significant for autos. The Ac2ated Sound system enables up to a 90-percent reduction compared to the average weight of a sound system. Vehicles with the top-tier trim levels generally weigh more than their mid-grade and base model counterparts, which causes them to be less fuel efficient.

"For Ac2ated Sound we have brought together the highest levels of expertise in the areas of acoustics, infotainment and vehicle design. In Sennheiser we have found an audio expert who helped us make our pioneering audio system even better," said Helmut Matschi, member of the Executive Board and Head of the business area Vehicle Networking and Information at Continental. "Together, we have developed an audio system that creates premium sound out of nowhere. Additionally, Ac2ated Sound reduces space and weight. At Continental, we call this sustainability that's music to your ears."

But, how does it sound? According to the companies, the result of the technology is a natural sound experience that, for the occupants, feels, "as if they are sitting in a concert hall surrounded by sound."

The technology, if implanted in passenger vehicles, would allow designers more leeway in designing an interior, saving 75-90 percent of the space of a traditional audio system. It also would make the vehicles more fuel efficient.

The new Maps+ app will allow drivers to use a navigation system who had not previously purchased navigation.

General Motors is giving its vehicles a new navigation solution. Maps+, an in-vehicle, app-based way-finding program, will begin rolling out to approximately 900,000 model year 2018 and newer Chevrolet, Buick, GMC and Cadillac vehicles by the end of 2021, starting on April 30.

"We know customers want an easy and convenient in-vehicle experience that improves over time," said Santiago Chamorro, GM vice president of Global Connected Services. "We listened to customer feedback and developed a product that works seamlessly with our current infotainment systems and provides a highly personalized experience that will iterate throughout the lifetime of the vehicle."

Maps+ was developed in partnership with Mapbox. The new app replaces navigation functionality in already-purchased vehicles that had purchased a navigation system. It provides navigation functionality to drivers of vehicles that did not opt for navigation at the onset.

The new application features Alexa build-in voice control that allows users to listen to music or podcasts using the system's integrated audio apps. A search box allows users to find points of interest, shops, restaurants, parking, and more. There is also embedded speed alert, low fuel recognition, predictive keyboard entry, day and night modes, category shortcuts, rear-time traffic routing, and dynamic mapping capability.

"Our obsession is the driver," said Peter Sirota, CEO of Mapbox. "The map is the canvas for providing the driver with a delightful, easy-to-use experience. From discovering new places to avoiding traffic on your commute to paying at the pump or the plug, Maps+ lays the foundation for an excellent navigation experience. We are excited to build upon this with GM to continue to drive adoption."

GM and Mapbox are committed to continuing Maps+ post-launch, developing new features and improvements based on feedback and metrics.

Maps+ will be available on select vehicles through Connected Vehicle, Premium and App Access subscription plans. Current eligible Chevrolet, Buick, GMC and Cadillac owners will be notified when their vehicle is eligible for Maps+.

New driver assist technology is coming to the Lexus lineup later this year.

New Lexus Teammate driver assistance technology will debut on the 2022 Lexus LS 500h later this year. Its availability is constrained to all-wheel drive models.

The technology was developed based on the Mobility Teammate Concept. This automated driving concept is unique to Toyota sough to enhance communication between drivers and cars, "enabling them to reach out to each other for mutual assistance". The concept sees cars and humans interacting and partnering rather than having automation take over for drivers. This approach allows drivers to enjoy the experience of driving but allowing the vehicle to take over some functions of driver's duties at times. In this way, the tech works as both guardian and chauffeur.

2022 Lexus LS 500h

On the 2022 Lexus 500h, Lexus Teammate will offer two functions: Advanced Drive and Advanced Park.

Advanced Drive is design to "accurately detect driving conditions to plan and execute acceleration, braking, and steering commands to maintain the vehicle within the lane, follow other vehicles, change lanes, navigate certain interchanges and traffic jams and overtake slower vehicles." It's a Level 2 functionality that "allows for driving on limited-access highways with partial hands-free, eyes-on-the-road operation".

This description makes it sound a lot like the suite of lane keeping, lane centering, and adaptive cruise control technology that Hyundai offers rather than true Level 3 technology that General Motors's Super Cruise delivers.

Advanced Park operates similar to how the Genesis GV80's hands-free parking assist technology works. The Lexus tech automatically controls steering, acceleration, braking, and gear changes with parallel parking or backing into a parking space. It uses a combination of 360-degree sensing technologies and a bird's eye view display to perform the task while allowing the driver to monitor progress.

"We are very proud of Lexus Teammate, which is the culmination of five years of close collaboration between our technical centers in Japan and the US. We conducted simultaneous development and rigorous testing in both markets with the goal of achieving industry-leading advanced driver assistance functionality," says Derek Caveney, executive engineer at Toyota Motor North America's Integrated Vehicle Systems team.
