CES 2017: High-resolution car services drive the development of intelligent autonomous vehicles.

The route to full-fledged autonomous driving is not a straight shot, but a puzzle. Yet all the necessary pieces are snapping into place faster and faster. Until 2025, level 4/5 capabilities (compare graph) that allow cars to take over for their human drivers will grow exponentially. And high-definition maps that are tightly linked to the cloud to bring in the latest information will play a key part in getting there.

That’s the message from Daimler’s Ola Källenius and Edzard Overbeek, head of the open mapping platform HERE. Speaking at an Inspiration Talk at the Mercedes-Benz stall at this year’s tech trade show CES in Las Vegas, both drove home the point that autonomous vehicles powered by HD and live maps are only a matter of time.

“The full transportation ecosystem, from cars to trucks, will benefit from autonomous driving. It’s a journey of building blocks, but eventually we’ll get to the prize: level 5 autonomous vehicles,” said Källenius, Member of the Board of Management of Daimler AG, responsible for Group Research & Mercedes-Benz Cars Development. He pointed to the fact that already today, more and more features let modern cars take over from the driver.

Working on autonomous vehicles

While bundles of sensors are the eyes and ears of the car, maps are one of the most important innovations to make sense of the various info streams, from navigation and points of interest to live weather and traffic plus behavioural data.

“When everything is digital, everything needs a location,” said Overbeek, CEO of Berlin-based HERE which was acquired by Audi, BMW and Daimler in 2015. At CES, it drew additional investment from chip giant Intel and also partnered with graphics chip maker NVIDIA to jumpstart work on autonomous systems.

Overbeek described HD maps as a key enabler of autonomous driving because they marry real-time sensor feeds from an individual car with data from the cloud at ten centimetre precision. “We can make cars intelligent already, bringing in weather and even the brake lights in front of us.”

Road information from the cloud

In its 25 year-long mapping effort, HERE has amassed 50 petabytes of data and is capturing the world with military-grade cameras, LiDAR sensors, and combining it with aerial footage and ultrasound. A direct outgrowth is a new offering called “electronic horizon” that HERE announced at CES.

Software embedded in the vehicle pulls in map data and dynamic road event data from the cloud to create a simplified representation of the road ahead with a range of a few hundred metres to several kilometres. It then feeds that model of the road to the car’s advanced driver assistance systems (ADAS) to optimise performance of the engine and safety systems. Before taking a highway exit, for instance, the system would know how slowly other drivers have taken the upcoming tight turn.

Even before full autonomy arrives, drivers and passengers already reap the benefits of live HD maps. “We’re moving from pure navigation in 2D to exploring things around us in 3D. We reduce the information density of a map and highlight just the important details in context,” explained Alexander Hilliger von Thile, senior manager advanced graphics and rendering at Mercedes-Benz Research and Development North America. “Maps of the future will dynamically change based on intelligent predictions before the journey even starts.”
