At CES in Las Vegas, HERE unveiled the HERE HD Live Map, an advanced cloud-based map asset commercially available for vehicles today. HERE is demonstrating HD Live Map at CES: Central Plaza, Booth #CP-2.

Ready to be deployed in connected vehicles in North America and Western Europe, HD Live Map creates a highly detailed and dynamic representation of the road environment, enabling a vehicle to effectively “see around corners” beyond the reach of its on-board sensors.

HD Live Map is an integrated offering, consisting of multiple layers of data delivered in a map-tile format. It is designed to enhance both Advanced Driver Assistance Systems (ADAS) and automated driving functionality, and therefore make driving more comfortable and enjoyable.

HD Live Map includes data which tends to have high permanency, such as lane level information; data which is temporal in nature, such as road construction, traffic and accidents; and analytics data, including speed profile information that informs the vehicle about how to drive based on actual human behavior data.

With highly automated driving set to become prevalent in the next few years, the immediate next step for the automotive industry is to capitalize on the new generation of ADAS that leverages wireless network connectivity and the cloud.

With HERE HD Live Map, automakers have the ability to enhance a vehicle’s ADAS functionality — such as adaptive cruise control, adaptive headlights and curve speed warnings — by giving it access to more accurate and more reliable near real-time content and contextual information about its environment. In doing so, the industry can help drivers build the prerequisite trust and familiarity they need to feel comfortable with increasing levels of vehicle automation.

“As we move towards higher levels of vehicle automation, drivers need to feel that their car is making the right decisions on their behalf,” Floris van de Klashorst, HERE’s vice president of automotive. “When it comes to trusting your car, having consistent real-time awareness of road conditions near and far is absolutely critical. With HD Live Map serving this need, we believe it will become the car industry’s most intelligent vehicle sensor.”

Self-maintaining map. HERE HD Live Map is the first map from HERE that is self-maintaining: through multiple modes of sensor aggregation and ingestion the vehicle’s map is updated and delivered in near real-time.

For example, if vehicle sensors detected a speed limit sign which is inconsistent with what is currently in the map, the map would update accordingly so that other vehicles driving approaching the same spot have the new, correct information. This is important for ADAS functionality such as adaptive cruise control.

Similarly, if a new lane closure was reported, the map would update accordingly so that other vehicles approaching the area can already prepare to switch lanes or alternatively re-route if traffic is heavy.

HERE HD Live Map delivers connected ADAS content via layered live tiles, with dynamic traffic flow data, real-time incident reporting and speed profile data derived from rich behavior information.

HD Live Map is also data-efficient, requiring a small data footprint, with new events able to be layered on the map without the need to update the whole map itself. The small file sizes within each live tile make the delivery of highly precise data much leaner, thus reducing bandwidth requirements.

In the near-term, HD Live Map utilizes a variety of data gathered and delivered by the HERE location platform to enhance the vehicle and the driver’s awareness of what’s happening on the road.

As vehicle automation increases in the future, HD Live Map is ready to serve as an agnostic location cloud, ingesting, aggregating and delivering in near real-time ever vaster quantities of data produced by a variety of sources, especially vehicle sensors. For example, HERE is exploring further enriching its platform with new sensor data from Audi, BMW and Mercedes-Benz vehicles, which would benefit all automakers deploying HD Live Map.

HERE has already been providing either parts or full specifications of HD Live Map for automated driving testing purposes to more than ten automotive companies. Many of those have taken advantage of HD Live Map data HERE is offering of specific stretches of open road in Silicon Valley and Michigan in the United States, as well as in France, Germany and Japan.

Now, with HD Live Map offered across key regions, HERE is able to support automakers seeking to widen and deepen their automated driving development efforts. In supporting larger testbeds, HERE intends to continue to refine HD Live Map together with automakers to ensure it is optimized for their needs today and tomorrow.

“Highly-detailed map data is not only very useful but a requirement for full-featured automated and autonomous driving. In the near term, highly-detailed map data will enhance the performance and benefits of current-generation driver assist technologies; over the longer term, they will enable more effective and efficient operation of vehicles altogether by drivers or self-driving cars. Adding a feedback loop to continually gather, update and share the latest road data will further elevate the technology’s potential,” analysts at IHS Automotive said.
