An apparatus (100) for determining road friction characteristics of a commercial vehicle (10) is disclosed. The commercial vehicle (10) comprises a first axle (11), a second axle (12), a load distribution mechanism (14) for changing a load (Fn) on the second axle (12) or the first axle (11), and a slip sensor (16) for determining a slip value of at least one wheel (17, 18) on the first axle (11) or the second axle (12). The device (100) has an evaluation unit (110) which is configured to: control the load distribution mechanism (14) in order to vary the load (Fn) on the second axle (12) or the first axle (11); determining a change in the slip value in response to a change in the load (Fn); and evaluating the road friction characteristic according to the change of the sliding value. 公开了一种用于确定商用车辆(10)的道路摩擦特性的设备(100)。所述商用车辆(10)包括第一车轴(11)、第二车轴(12)、用于改变所述第二车轴(12)或所述第一车轴(11)上的负载(Fn)的负载分配机构(14)以及用于确定所述第一车轴(11)或所述第二车轴(12)上的至少一个车轮(17、18)的滑动值的滑动传感器(16)。所述设备(100)具有评估单元(110)，所述评估单元配置为能够：控制所述负载分配机构(14)以改变所述第二车轴(12)或所述第一车轴
