The invention relates to a method for determining a coefficient of friction (μ) between a wheel (7,70) of a motor vehicle and a road surface (16), wherein the motor vehicle has a Einzelradantrieb, which is adapted to the wheel (7,70) regardless of to drive the at least one other wheel (7, 70) of the motor vehicle, the following method steps being provided: applying a wheel drive torque (M impulse ) to the wheel (7, 70) of the motor vehicle by the individual wheel drive, such that the wheel ( 7,70), and determining the coefficient of friction (μ) by means of the friction torque (M friction ), which is the difference of the wheel drive torque (M impulse ) and an inertia (M inertia ) of the wheel (7, 70). |
