The invention relates to a method (900) for operating a tractor-trailer unit (100) consisting of a tractor (104) and a trailer (106). In a reading step (902) of said method, input variables (108) on the tractor (104) and the trailer (106) are read. The input variables (108) include payload data (306) on a payload (mload, mtrailer) of the tractor-trailer unit (100), torque data (308) on a torque (M) acting on a powertrain of the tractor (104), brake pressure data (310) on brake pressures (P1, P2, P3, Ptrl) provided in the tractor-trailer unit (100), and gradient angle data (312) on a gradient angle (α) of a roadway below the tractor-trailer unit (100). In a determination step (904), output variables (110) are determined using the input variables (108) and a processing rule (314). The output variables (110) include front axle load data (316) on an axle load (m) acting on a front axle of the tractor (104) as well as rear axle data (318) on an axle load (m) acting on a rear axle of the tractor (104). In a utilization step (906), the output variables (110) are used for controlling a brake system of the tractor-trailer unit (100) in order to operate the tractor-trailer unit (100).
