METHOD FOR PERFORMING A DIAGNOSIS IN A MOTOR VEHICLE

摘要

The invention relates to a method for performing a diagnosis in a motor vehicle (50) in which a time curve of at least one physical variable is detected when the motor vehicle (50) is in operation, said time curve undergoing a frequency analysis such that a frequency spectrum which is characterised by the frequency spectrum data is obtained. Said frequency spectrum data is evaluated and the evaluation is taken into account when operating the motor vehicle (50).
