In this work, methods of estimation of road roughness by processing data of laser sensors of distance measurement are investigated. Depending on the layout of the sensors and the processing of the data, the Japanese, symmetrical and asymmetrical roughness estimation methods are elaborated in this work. The experimental research that was carried out by “Japanese method” on two known profile road surfaces allowed evaluating the influence of the vehicle’s suspension and the body pitch rate oscillation on the calculation of the roughness. The validation of the results showed that the compensation of the suspension travel does not warrant the sufficient accuracy of the estimation of the road roughness because the pivoting of the bodywork has a greater influence on the processing of the signals recorded by the sensors attached to it.

Artykuł przedstawia i ocenia metody określania nierówności nawierzchni drogi na podstawie danych z laserowych czujników pomiaru odległości. W artykule omówiono opracowane w Japonii symetryczne i asymetryczne metody określania nierówności nawierzchni, które różnią się sposobem rozmieszczenia czujników i przetwarzania danych. Badania eksperymentalne przeprowadzone na podstawie „metody japońskiej” na dwóch zadanych profilach nawierzchni pozwoliły na ocenę wpływu zawieszenia samochodu i zmian przechyłu nadwozia względem osi podłużnej na obliczanie nierówności nawierzchni. Walidacja wyników pokazała, że kompensacja odchylenia zawieszenia nie zapewnia wystarczającej dokładności pomiaru nierówności drogi, ponieważ przechyły nadwozia mają większy wpływ na przetwarzanie sygnałów rejestrowanych przez zamontowane na nim czujniki.
