Abstract
A device for the recording, storing and outputting of data of a control unit in a motor vehicle, besides the operating time of the control unit, makes it possible for other data to be acquired and stored as well, so that information will be provided regarding the probability of failure or the future reliability of the control unit. Noteworthy as these additional data is at least one of the quantities:
maximum control-unit temperature
duration of a control-unit temperature above a certain value
minimum control-unit temperature
duration of a control-unit temperature below a certain value
maximum value of the voltage on the supply-voltage line
length of time a supply voltage is applied above a certain value
duration and intensity of interference voltages on control-unit lines.
