Method for determining roof load mounted in vehicle e.g. motor car, involves comparing measurement waveform of detected vehicle vibrations with characteristic measured quantity to determine roof load on vehicle

摘要

The method involves detecting measurement signal modulated by the roof load (1) using a sensor (4). The roof load characteristic measured quantity is derived from the measurement signal. The vehicle is excited and vibrations are detected. The measurement waveform of the detected vehicle vibrations is compared with the characteristic measured quantity to determine the roof load on the vehicle (3).
