provide assistance during driving, for instance
driver assistance systems. Furthermore, control
devices facilitate comfort or infotainment func‐
tions.
Information about stored or exchanged data can
be requested from the manufacturer of the vehi‐
cle, in a separate booklet, for example.
Personal reference
Each vehicle is marked with a unique vehicle
identification number. Depending on the country,
the vehicle owner can be identified with the vehi‐
cle identification number, license plate and corre‐
sponding authorities. In addition, there are other
options to track data collected in the vehicle to
the driver or vehicle owner, e.g. via the Connec‐
tedDrive account that is used.
Operating data in the vehicle
Control units process data to operate the vehicle.
For example, this includes:
Status messages for the vehicle and its indi‐
vidual components, e.g., wheel rotational
speed, wheel speed, deceleration, transverse
acceleration, engaged safety belt indicator.
Ambient conditions, e.g., temperature, rain
sensor signals.
The processed data is only processed in the ve‐
hicle itself and generally volatile. The data is not
stored beyond the operating period.
Electronic components, e.g. control units and ig‐
nition keys, contain components for storing tech‐
nical information. Information about the vehicle
condition, component usage, maintenance re‐
quirements or faults can be stored temporarily or
permanently.
This information generally records the state of a
component, a module, a system, or the environ‐
ment, for instance:
Operating states of system components,
e.g., fill levels, tire inflation pressure, battery
status.
Malfunctions and faults in important system
components, for instance lights and brakes.
Responses by the vehicle to special situa‐
tions such as airbag deployment or engage‐
ment of the driving stability control systems.
Information on vehicle-damaging events.
The data is required to perform the control de‐
vice functions. Furthermore, it also serves to rec‐
ognize and correct malfunctions, and helps the
vehicle manufacturer to optimize vehicle func‐
tions.
The majority of this data is transient and is only
processed within the vehicle itself. Only a small
share of the data is stored event-related in event
or fault memories.
When servicing, for instance during repairs, serv‐
ice processes, warranty cases, and quality assur‐
ance measures, this technical information can be
read out from the vehicle together with the vehi‐
cle identification number.
A dealer’s service center or another qualified
service center or repair shop can read out the in‐
formation. The socket for OBD Onboard Diagno‐
sis required by law in the vehicle is used to read
out the data.
The data is collected, processed, and used by
the relevant organizations in the service network.
The data documents technical conditions of the
vehicle, helps with the identification of the fault,
compliance with warranty obligations and quality
improvement.
Furthermore, the manufacturer has product
monitoring duties to meet in line with product lia‐
bility law. To fulfill these duties, the vehicle man‐
ufacturer needs technical data from the vehicle.
The data from the vehicle can also be used to
check customer claims for warranty and guar‐
anty.
Fault and event memories in the vehicle can be
reset when a dealer’s service center or another
qualified service center or repair shop performs
repair or servicing work.
