PreviewESC - powered by eHorizon


PreviewESC observes the road ahead by evaluating dynamic friction map data provided by eHorizon. Acting as a virtual sensor eHorizon provides a friction map based on estimated friction values as well as on predicted road surface conditions. PreviewESC will warn the driver and intervene before a vehicle velocity is likely to cause a stability critical situation.

  • Localization of the vehicle by GPS
  • eHorizon provides curvature and road friction on the road ahead
  •  Friction data generation based on crowd-sourced approach from previous vehicles
  • PreviewESC determines the max. velocity based on received eHorizon data and vehicle dynamics
  • PreviewESC performs deceleration control

Driving experience

  • Demonstration of a predictive ESC function, powered by eHorizon 
  • End-to-End capability from one supplier
  • Product lifecycle experience: vehicle collects friction value, provides it to, loops aggregated/normalized values back to vehicles / PreviewESC
  • In case of inappropriate speed PreviewESC intervenes to ensure the Stability


  • Avoid a stability critical situation of the vehicle
  • Warns driver on upcoming critical situation
  • Protects the vehicle from road departures
  • Increase driving stability on curvy roads
