4 Data
memory
A variety of electronic components of the machine contains data memories that save
temporarily and permanently technical information on machine condition, events and errors.
This technical information generally documents the condition of a part, module, system or of the
environment:
–
Operating states of system components (e.g. filling levels)
–
Status messages of the machine and its single components (e.g. number of revolutions of
wheel, wheel speed, retardation of movements, lateral acceleration)
–
Malfunctions and defects in important system components (e.g. light and brakes)
–
Reactions of machine in special driving situations (e.g. actuation of airbag, installing stability
control systems)
–
Ambient conditions (e.g. temperature)
These data are exclusively of a technical nature. They are used to detect and remedy errors as
well as to optimize machine functions. There is no possibility to create motion profiles on driven
routes from these data.
If services are occupied (e.g. repair services, service processes, warranty cases, quality
assurance), this technical information can be read by employees of service network (including
manufacturer) from the event and error data memory by means of special diagnostic units.
There you receive further information, if necessary. After the error has been remedied, the
information in the error storage is either deleted or overwritten continuously.
When using the machine, situations are possible in which these technical data in connection
with other information (accident protocol, damage to the machine, testimonies etc.) could
become transferable to people - if applicable in consultation with an expert.
Additional functions regulated by a contractual agreement with the customer (e.g. remote
maintenance) permit the transmission of certain machine data from the machine.
