Customer information261This data includes, for example:● Vehicle status information (e.g. wheel rotation rate, speed,
movement delay, lateral
acceleration, "seatbelts
fastened" display),
● Ambient conditions (e.g. temperature, rain sensor,
distance sensor).
Most of this data is volatile and is processed only in the vehicle itself,and not beyond the operating time.
Moreover, many control units include
data storage device (amongst others the vehicle key). This is used to allow
information to be documented
temporarily or permanently on vehicle
condition, component stress,
maintenance requirements and
technical events and errors.
The following information, for
example, is stored:
● System component operating states (e.g. fill level, tyre
pressure, battery status),
● State of charge of the high voltage battery, estimated range
(in the case of electric vehicles),● Faults and defects in important system components (e.g. lights,
brakes),
● System reactions in special driving situations (e.g. triggeringof an airbag, actuation of the
stability control systems),
● Information on events damaging the vehicle.
In special cases (e.g. if the vehicle
has detected a malfunction), it may be
necessary to save data that would
otherwise just be volatile.
When you use services, the operating data saved can be read together withthe vehicle identification number andused if necessary. Staff working for
the service net-work (e.g. garages,
manufacturers) or third parties (e.g.
breakdown services) can read the
data from the vehicle. Services
include repair services, maintenance
processes, warranty cases and
quality assurance measures.
Data is generally read via the OBD
(On-Board Diagnostics) port
prescribed by law in the vehicle. The operating data which has been read
out documents the technical conditionof the vehicle or individual
components and assists with fault
diagnosis, compliance with warranty
obligations and quality improvement.
This data, in particular information on
component stress, technical events,
operator errors and other faults, is
transmitted to the manufacturer
where appropriate, together with the vehicle identification number. The
manufacturer is also subject to
product liability. The manufacturer
potentially also needs operating data
from vehicles for product recalls.
Fault memories in the vehicle can be
reset by a service company when
carrying out servicing or repairs.
Comfort and infotainment
functions
Comfort settings and custom settings can be stored in the vehicle and
changed at any time.
