A current tire stiffness (St) is determined from the calculated current friction value demand (μ) and a current tire slip (Slip), and the current road friction value (μ) is determined from the current tire stiffness (St) by way of a stored table (T), which maps tire stiffnesses (St) to road friction values (μ).",
