Precise data for greater safety:
Audi warns its drivers faster about slippery roads

Car-to-X services
  • Swarm data improves car-to-X service “Local Hazard Information”
  • Around 1.7 million cars in the Group make up the swarm intelligence
  • New procedure detects the smallest changes in friction coefficient
  • Joint development between Audi and Car.Software organization, NIRA, and HERE

Audi is taking another step toward safer and more intelligent mobility. The premium carmaker is using high-precision swarm data for the first time to improve its car-to-X service “Local Hazard Information” (LHI). The new version uses a car-to-cloud application that is based on a novel procedure for estimating the coefficient of friction on the basis of the wheel slip. This technology can detect the tiniest changes in road surface adhesion, upload data to the cloud for processing, and warn upcoming drivers of road ice or other slippery conditions in near real time.
