Abstract
The invention concerns a method for operating a motor vehicle with selectable all-wheel drive. The all-wheel drive is implemented with no central differential and the rear axle is implemented with no axle differential. The motor vehicle includes first and second partial clutches for independently decoupling left and right rear wheels from the drive train of the motor vehicle motor vehicle. The method includes determining a value that is representative of a ratio of the speeds of the front wheels to each other, comparing the value with a reference value, and disengaging the partial clutch that is associated with an outer rear wheel when the motor vehicle is turning, when the value is greater than the reference value, in order to prevent negative torques on the outer rear wheel.
