Abstract
A method controlling operation of a mechanism mechanically coupling first and second axles of a transmission system of a motor vehicle, the first axle being driven as standard and the second axle being driven as an option depending on a status of the coupling mechanism, the transmission system being capable of operating in a first mode in which a value of transmittable torque that can be transmitted by the mechanical coupling mechanism is fixed, or in a second mode in which the value of the transmittable torque that can be transmitted by the mechanical coupling mechanism is higher than the value of the transmittable torque for the first mode.
