The invention relates to a method for operating a drive train of a motor vehicle (10), with the steps: detecting at least one variable (Mmot,pot, Fz,ist, Fy,ist, Mmax, FX,ist, VRadVL, VRadVR, VRadHL, VRadHR, δRad, VRef, ψ, ay, ψs, v, US, OS) quantifying and/or influencing a movement of the motor vehicle (10); depending on the variable (Mmot,pot, Fz,ist, Fy,ist, Mmax, Fx,ist, vRadVL, VRadVR, VRadHL, VRadHR, δRad, vRef, ψ, ay, Ψs, v, US, OS), switching on an all-wheel drive of the motor vehicle (10); wherein it is estimated on the basis of the at least one variable (Mmot,pot, FZ,ist, Fy,ist, Mmax, Fx,ist, VRadVL, VRadVR, VRadHL, VRadHR, δRad, vRef, ψ, ay, ψs, V, US, OS) whether a relevant driving situation is impending and in this case the all-wheel-drive is switched on before occurrence of the relevant situation. The invention further relates to a system for operating a drive train of a motor vehicle (10). |
