Precision maps feature near real-time 'self-healing'
Daimler and HERE Technologies have teamed to make HERE HD Live Map a part of Daimler’s autonomous driving technology. The machine-readable, cloud-based HD Live Map allows an automated vehicle to effectively “see around corners” and consists of multiple layers of information essential for it to know where exactly it is, what lies ahead, and what it should do in various scenarios.
The HD Live Map was designed to be “self-healing.” This means it can reflect dynamic changes in the road environment and update itself accordingly in near real-time. The self-healing ability enables vehicles to proactively adjust to changing road conditions, such as switching lanes and adjusting speed ahead of time in the case of an upcoming lane closure.
Vehicle sensor data is crucial for an HD map to self-heal because of its quality and the sheer volume of vehicles on the road that can detect and validate change. HERE HD Live Map reportedly constantly publishes changes to the map through a content validation process, by which multiple vehicle sensors act as a “closed loop” to detect any deviations from the published data.
“The map of the future is one that’s self-healing—constantly updating to mirror what is happening across the road network,” said Ralf Herrtwich, SVP Automotive at HERE Technologies. “Together with Daimler, we are mastering this powerful mapping technology and are truly excited to make it available for the next generation of Mercedes-Benz vehicles.”
Ola Källenius, member of the Board of Management for Group Research and Mercedes-Benz Cars Development, emphasized, “Maps with centimeter precision updating themselves in near real-time, is one key element for autonomous driving. With the new HD Live Map and the rich, continuously growing information it provides, we are taking a big step on the way towards autonomous driving.”
