PreviewESC - powered by eHorizon
Scope
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.

Technology
- 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 Continental.cloud, loops aggregated/normalized values back to vehicles / PreviewESC
- In case of inappropriate speed PreviewESC intervenes to ensure the Stability
Benefits
- Avoid a stability critical situation of the vehicle
- Warns driver on upcoming critical situation
- Protects the vehicle from road departures
