Electr Electronic contr onic control units ol units
Electronic control units are tted in your vehicle.
Control units process data which, for example,
they receive from vehicle sensors, generate them-
selves or exchange between themselves. Some
control units are required for the safe operation of
your vehicle, some assist you when driving, such
as driver assistance systems, while others enable
convenience or infotainment functions.
The following provides you with general informa-
tion regarding data processing in the vehicle.
Additional information regarding exactly which
data in your vehicle are collected, saved and
transmitted to third parties, and for what purpose,
can be found in the information directly related to
the functional characteristics in question in their
respective operating instructions. This information
is also available online and, depending on the
vehicle equipment, digitally.
PPer ersonal data sonal data
Every vehicle is identi ed by a unique vehicle
identi cation number. Depending on the country,
this vehicle identi cation number can be used by,
for example, governmental authorities to deter-
mine the identity of the owner. There are other
possibilities to use data collected from the vehicle
to identify the owner or driver, such as the licence
plate number.
Therefore, data generated or processed by control
units may be attributable to a person or, under
certain conditions, become attributable to a per-
son. Depending on which vehicle data are availa-
ble, it may be possible to make inferences about,
for example, your driving behaviour, your location,
your route or your use patterns.
Leg
Legal r al req equir uirements r ements reg egar arding t ding the disclosur he disclosure of e of
data data
If legally required to do so, manufacturers are, in
individual cases, legally obliged to provide govern-
mental entities, upon request and to the extent
required, data stored by the manufacturer. For
example, this may be the case during the investi-
gation of a criminal o ence.
Governmental entities are themselves, in individ-
ual cases and within the applicable legal frame-
work, authorised to read out data from the vehi-
cle. In the case of an accident, information that
can help with an investigation can, therefore, be
taken from the airbag control unit, for example.
Oper
Operational dat ational data in t a in the v he vehicle ehicle
This is data regarding the operation of the vehicle,
which have been processed by control units.
This includes the following data, for example:
R
vehicle status information such as the speed,
longitudinal acceleration, lateral acceleration,
number of wheel revolutions or the fastened
seat belts display
R
ambient conditions, such as temperature, rain
sensor or distance sensor
Generally, the use of these data is temporary;
they will not be stored beyond the period of oper-
ation and will only be processed within the vehicle
itself. Control units o en contain data memories
for vehicle keys, for example. Their use permits
the temporary or permanent documentation of
technical information about the vehicle's operat-
