发明名称 METHOD OF OPERATING A TRANSMISSION SYSTEM OF AN AUTOMOTIVE VEHICLE OF THE FOUR-WHEEL DRIVE TYPE COMPRISING A MEANS OF MECHANICALLY COUPLING THE FIRST AND SECOND AXLES
摘要 A method of operating a transmission system of an automotive vehicle, the transmission system including a mechanism of mechanically coupling first and second axles of the transmission system, a status of the coupling mechanism defining a number of transmission modes. In the method, if the automotive vehicle crosses a speed threshold for a determined length of time, for example between 30 seconds and two minutes, the transmission system switches from a first mode in which the torque that can be transmitted by the mechanical coupling mechanism is fixed, into a different transmission mode.
