- This study analyzed the possibilities to validate the indications of sensors for yaw rate and lateral acceleration within the scope of extended diagnostic routine of the car ESP system at Vehicle Inspection Stations. The stand tests were performed using the reference sensors and a standard diagnostic tester. The comparison of the yaw rate and lateral acceleration results obtained from the working sensor under examination, recorded with the Vbox unit, and the results from the reference sensor demonstrated a good conformity both in quality and quantity. But these tests demonstrated also a pure conformity (both in quality and quantity) with runs obtained from tester. The Root Mean Square (RMS) was used as factor of qualitative estimation. These inconveniences were caused by in sampling frequency incompatibility and lack of recording synchronization for signals from the tester and from reference sensors. The question of primary importance is a firmware modification for selected testers. Such a tester should be able to record signals from a reference sensor and have a set sampling frequency for signals from a working sensor. On the basis of already carried out research analyses the suggested frequency should be no lower than approximately 10 Hz. It resulted from a spectral analysis carried out for possessed runs maintaining the Nyquist limit frequency.
