Abstract
The invention relates to a method of storing information in the form of signals from a control system in a vehicle, said method comprising the step of reading a signal on recurrent sampling occasions and increasing the value of a counter which represents a signal value interval. The method further comprises the steps of measuring on each sampling occasion a change of the signal in relation to a previous signal value, comparing change with the threshold value, and, if the change is greater than the threshold value, increasing the value of a counter associated with this threshold value.
