The invention relates to a method for determining a friction coefficient (μ) between a wheel (7, 70) of a motor vehicle and a road surface (16), wherein the motor vehicle has an individual wheel drive, which is designed to drive the wheel (7, 70) independently from the at least one other wheel (7, 70) of the motor vehicle, wherein the following method steps are provided: applying a wheel drive torque (MImpuls) to the wheel (7, 70) of the motor vehicle via the individual wheel drive, in such a way that the wheel (7, 70) is caused to slip; and determining the friction coefficient (μ) by means of the friction torque ( MReibung), which results from the difference between the wheel drive torque (MImpuls) and an inertia moment (MTrägheit) of the wheel (7, 70).
