DEVICE FOR ESTIMATING AN INDICATOR OF THE STATE OF A TRAFFIC ROUTE TAKEN BY A LAND VEHICLE

摘要

The invention relates to an analysis device (DA) provided in a land vehicle (VT) travelling on a traffic route (VC) and including a structure for supporting one or more passengers. Said device (DA) comprises processing means (MT) arranged to estimate at least one dominant frequency fp in at least one signal Z(t) representing excitations of the structure at a time t, and then to determine a value of an indicator representing the state of the traffic route (VC) in accordance with at least said estimated dominant frequency fp.
