How it works

Increase safety based on real-time information

1. Identify dangerous traffic events

Based on their ABS and ESP sensors our connected Mercedes-Benz vehicles detect a wide variety of dangerous situations, e.g. slippery roads via tire sensors, broken down vehicles on the emergency lane or accidents that have just happened. These and other events are transmitted to the Mercedes-Benz Data backend and made available to our customers in anonymized form.

2. Get information about weather conditions

Classic weather service data does not capture local road sections, the sensor technology of the Mercedes-Benz vehicle fleet helps out here. If the vehicle sensors identify heavy rainfall, fog or dangerous crosswinds, we are happy to make this data available to increase safety on the roads.

Learn about the Mercedes-Benz vehicle fleet from potholes, among other things, perceived by the vehicle sensors. Valuable information for your customers.
Warn about slippery roads using our real-time sensor data to protect road users in the immediate vicinity from the hazard.
Do not allow motorists to drive into poor visibility conditions without timely warning.
