Abstract

In a method for determining a roadway state (STATE) of a roadway on which a vehicle (10) is travelling which has at least one wheel (14) and an acceleration sensor (24) which is assigned to the wheel (14), in order to determine a vertical component of an acceleration of the wheel (14), a characteristic value which is representative of the roadway state (STATE) is determined as a function of a measured signal (AC_VERT) of the acceleration sensor (18).
