At CES 2016, HERE introduces HD Live Map, which is 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 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. These maps require a small data footprint, with new events able to be layered on the map without the need to update the whole map itself.
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.
With this, automakers will 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.
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.
