Overview
This document contains information on the function requirements and function of Car-to-X-Communication.
General
Car-to-X-Communication enables wireless information exchange between vehicles, but also between vehicles and transport infrastructure. Car-to-X-Communication makes it possible to share information regarding dangerous situations that a vehicle has detected in road traffic with all other Car-to-X-Communication users. As with Live Traffic Information, messages distributed via Car-to-X are displayed in the navigation map in the multimedia system. When approaching a hazardous area, Car-to-X warns the driver either visually or acoustically depending on the type of message. The data exchange takes place via the telematics services control unit.
Function requirements
- Service is activated.
- Service is available in your country.
- The telematics services control unit is connected with the Daimler Vehicle Backend (DaiVB).
Function
The multimedia system recognizes hazardous situations automatically and reports these together with position information to the Daimler Vehicle Backend (DaiVB).
For Car-to-X-Communication, the multimedia system evaluates the following information in the vehicle to detect hazardous situations:
- Hazard warning system
- Rear fog lamp
- Windshield wiper
- Accident and breakdown management (crash information, emergency call)
- Vehicle speed
- Low-grip signal from ESP®
- GPS position and time
The driver also has the option to manually distribute a message about a general hazard via the multimedia system.
Daimler AG checks messages received in DaiVB for plausibility. All vehicles participating in Car-to-X-Communication regularly report their position to DaiVB and then receive messages relevant to their surroundings.
Daimler AG pseudonymizes the data, meaning that any data which might be used for identification is replaced. Daimler AG deletes the data after an adequate amount of time (a few weeks).
The multimedia system displays e.g. the following warnings in the navigation map using corresponding symbols:
Information on moving construction sites comes from an external provider.
When approaching a hazardous area, the warning is issued via the voice output from a vehicle speed of at least 60 km/h. There is no warning via voice output for weather hazards.
