Harman maintains the new 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 solution can reduce the size of a map update to as low as 2.5% of the original size of the full map image in a failsafe and secure manner.

“The maps we use on our smartphones today are suitable for consumers who can understand simple navigation instructions,” said Harman SVP, Software Platforms, Connected Services, Oren Betzaleli. “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.

“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.”

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.

  • New, built-in Smart Delta technology
  • Support of various maps based on Navigation Data Standard (NDS)
