The invention relates to a method for operating a drivetrain of a motor vehicle (10). The method includes following steps: detecting at least one variable (Mmot, pot, Fz, ist, Fy, ist, Mmax, FX, ist, VRadVL, VRadVR, VRadHL, VRadHR, deltaRad, VRef, Psi, ay, Psis, v, US, OS) quantifying and/or influencing a movement of the motor vehicle (10); and depending on the variable (Mmot, pot, Fz, ist, Fy, ist, Mmax, Fx, ist, vRadVL, VRadVR, VRadHL, VRadHR, deltaRad, vRef, Psi, ay, Psis, 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, deltaRad, vRef, Psi, ay, Psis, 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 drivetrain of a motor vehicle (10).
