A method for determining a current road friction value (μroad) using a control device in a motor vehicle continuously calculates a current friction value demand (μdem) by the control device. A current tire stiffness (St) is determined from the calculated current friction value demand (μdem) and a current tire slip (Slip), and the current road friction value (μroad) is determined from the current tire stiffness (St) by way of a stored table (T), which maps tire stiffnesses (St) to road friction values (μroad).
