Car2X communication
Introduction
How Car2X works
1)
Car2X enables communication between sev-
eral vehicles, as well as between vehicles and
the road infrastructure (hereinafter referred to
as “participants”) in the vicinity. Communica-
tion between the participants is established
in accordance with Car2X and WLAN (Wi-
Fi) standards, regardless of the manufacturer.
Car2X only works in some countries.
When Car2X is connected, data are transmit-
ted permanently between the participants, re-
gardless of whether their vehicle is in online or
oline mode.
To prevent misuse and to sign Car2X data
with changing IDs, Car2X data transmitter must
have valid certicates. This means that each of
the recipients can check that the Car2X data
are authentic and that they come from a legiti-
mate participant.
The vehicle’s own certicates can only be re-
newed automatically in online mode.
To update the Car2X certicates to ensure
that Car2X remains active, activate the Online
mode in the vehicle at least once a month.
Continuously changing provisional Car2X data
IDs minimise the probability that the data that
is sent can be linked to you personally.
Meaning of the symbol
Indicates that the connected Car2X also
sends and receives data in Oline mode.
Data transmissions
When Car2X is connected, the following data
are sent and received via the Car2X antennas:
●
Vehicle data such as speed.
●
Position data.
●
Data about incidents, e.g. accidents.
Car2X distinguishing element
If you can switch on Car2X communication in
Privacy settings in the infotainment system,
this means that the vehicle is tted with Car2X
technology.
