Abstract
A motor vehicle with four drive wheels mounted on first and second axles, including: a transfer shaft connected to the first axle and a controlled coupling that can transfer part of the torque from the transfer shaft to the second axle; a mechanism determining respective speeds of the first and second axles, and a torque distribution control system configured to determine a slip value representative of the speed difference between the first and second axles and to control the coupling. The torque distribution control system is further configured to control the coupling such as to suppress any torque transfer via the coupling when the average slip value over a pre-determined period exceeds a threshold.
