HARMAN’s Smart Delta for Maps enables OEMs, map providers to deliver updates, enhance ADAS, automated driving features

HARMAN , a wholly-owned subsidiary of Samsung Electronics, announced on Tuesday Smart Delta for Maps for connected vehicles. This product will allow car manufacturers to push new HD Maps updates in greater frequency, so drivers can benefit from up-to-date information, such as available parking spots or recent road works in near real-time.

The resource-efficient product, which is part of the company’s Over-The-Air (OTA) solution, resolves major challenges Smart Delta for Maps face currently – limited size updates, and difficulties in updating over intermittent LTE or Wi-Fi Coverage.

HARMAN’s new solution can reduce the size of a map update to as low as 2.5 percent of the original size of the full map image in a failsafe and secure manner. HARMAN has re-engineered the update process, which typically take days, to occur near real-time with this new product.

HARMAN Remote Vehicle Updating Service (OTA) with the new Smart Delta for Maps product are designed to provide a reliable and superior user experience through its new, built-in Smart Delta technology; support of various maps based on Navigation Data Standard (NDS); advance connected urban driving with efficient Point of Interest (PoI) updates; and update only new data within the layer(s) of a map.

Maps can take upwards of 8 to 20 GB of data. HARMAN’s new Smart Delta for Maps can seamlessly integrate with a map provider’s OTA service, allowing the OEM to leverage this new technology and continuously keep their customers’ Navigation System up-to-date. Irrespective of the frequency of the map update releases and location, Smart Delta technology enables automotive OEMs and map companies to provide up-to-date map content across fleets and to multiple individual customers regardless of the OTA solution they use.

“The maps we use on our smartphones today are suitable for consumers who can understand simple navigation instructions. However, as we move to Level 3 or 4 semi-autonomous vehicles, the need to make decisions on the road, will increase and will require more detailed and accurate maps,” said said Oren Betzaleli, HARMAN’s senior vice president for software platforms and connected services. “HARMAN’s new Smart Delta for Maps for Connected vehicles, will allow OEMs and map providers to dramatically reduce the size of map updates using this technology, and by extension reduce the cost, transfer and amount of storage required on the vehicle.”
