A method and system is provided for acquiring and analyzing vehicle motion signals to determine vehicle performance. The sampled vehicle motion signals are transferred from the time domain to the frequency domain using online frequency analysis. Once the frequency spectrum for the sampled vehicle motion data is obtained, the main frequencies and associated amplitudes are identified. Depending on the type of test conducted and the vehicle components to be analyzed, the natural frequencies of interest will be known and identified in the frequency spectrum. Online frequency analysis is used for analyzing the pre-defined frequencies in embedded systems with restricted computational resources and storage facilities. A weight filter matrix is used to calculate the frequency spectrum of interest in real time. The matrix is pre-calculated in accordance with a given sampling time, sampling rate, and selected frequencies.
