| 摘要 |
Provided is a synchronized travel assistance device, comprising: a first acceleration power spectrum acquisition means for acquiring a first acceleration power spectrum from a first vehicle acceleration; a second acceleration power spectrum acquisition means for acquiring a second acceleration power spectrum from a second vehicle acceleration; a cross-power spectrum computation means for computing a cross-power spectrum between the first vehicle and the second vehicle using the first acceleration power spectrum and the second acceleration power spectrum; a coherence computation means for computing coherence from the cross-power spectrum; and a correlation evaluation means for evaluating correlation in synchronized travel of the first vehicle and the second vehicle on the basis of the coherence. |
