摘要: A method is provided for monitoring a state of health of a vehicle system and includes measuring a plurality of parameter values for the system at different running conditions as an end of line test, storing the parameter values in a fingerprint file, measuring the same plurality of parameter values that is comprised in the fingerprint file after a predefined time interval, adding a predefined, ageing offset to the fingerprint file, where the ageing offset corresponds to a predicted wear of the system during the predefined time interval, thereby obtaining a time modified fingerprint file for the system, comparing the measured values with the time modified fingerprint file, and issuing a message if the measured values deviates from the time modified fingerprint file. The state of health can be compared with initial measurements such that the state of health of a vehicle system or component can be monitored over a longer time period.
