摘要： A signal waveform analysis method includes: determining a trend component of an object signal by applying a zero-phase filter to the object signal; determining an oscillatory component of the object signal by removing the trend component from the object signal; determining a wavelet scalogram by performing a wavelet analysis on the oscillatory component; and determining an oscillation period of the object signal with which the wavelet scalogram indicates a maximum. The signal waveform analysis method is employed to evaluate vehicle dynamic characteristics.
