  • Patent number: 10293687
    Abstract: A control apparatus for a four-wheel drive vehicle includes a current detector configured to output a detection signal in accordance with the magnitude of an actual control current, a target current value calculator configured to calculate a target current value that is a target value of the control current, and a current controller configured to control a current output circuit to output the control current having the target current value calculated by the target current value calculator based on a result of detection performed by the current detector. When the four-wheel drive vehicle is in a two-wheel drive mode in which first and second friction clutches are released, the current controller performs zero-point adjustment for adjusting a zero point of the control current to be output from the current output circuit.

  • Patent number: 10286893
    Abstract: A device for operating an all-wheel-drive agricultural commercial vehicle with a driven rear axle and a front axle that can be engaged for performing an all-wheel-drive mode. A control unit determines, during the all-wheel-drive mode, a front wheel slip parameter that characterizes a drive wheel slip occurring on the front axle of the agricultural commercial vehicle. The control unit deactivates the all-wheel-drive mode independent of the driver if this unit detects that the determined front wheel slip parameter is greater than a specified threshold value.
