  • Method for the automatic control of the locking clutches of an all-wheel driven vehicle, and vehicle with articulated-vehicle steering and lockable differentials
    Patent number: 6009969
    Abstract: A method for the automatic locking of the differentials of an all-wheel driven vehicle, slip signals being formed which, as soon as they exceed a threshold value, initiate the driving of the respective differentials. In order to take into account the influence of the steering rolling radius, the change in the steering value is ascertained. From this, using a function determined by the geometry of the vehicle, an apparent slip is ascertained. From the respective apparent slip, corrected threshold values are determined and measured slip signals are compared with the corrected threshold values and, if necessary, the driving of the respective differential is initiated. The method can also be used on a vehicle having articulated-vehicle steering.
