Zusammenfassung:	An apparatus (100) for determining a road friction of a commercial vehicle (10) is disclosed. The commercial vehicle (10) comprises a first axle (11) and a second axle (12), a load distribution mechanism (14) for changing a load (Fn) on the first axle (11) or on the second axle (12), and a slip sensor (16) for determining a slip value for at least one wheel (17, 18) on the first axle (11) or on the second axle (12). The apparatus (100) includes an evaluation unit (110) configured: to control the load distribution mechanism (14) to change the load (Fn) of the first axle (11) or on second axle (12); to determine a change in the slip value in response to the change of the load (Fn); and evaluate the road friction based on the change in the slip value.
