A method for controlling a power-split gear shift device in a vehicle by providing an electric variator and a transmission with variable gear shift and connecting a drive motor to a traction drive of the vehicle. The electric variator has a compound gear train with at least one first and at least one second electric machine. The method also includes providing a controller for the electric machines for steplessly varying a gear shift of the compound gear train. Upon detection of an external power requirement by an electric consumer, a gear shift region of the transmission with variable gear shift is set to operate the first electric machine in a generator mode and to operate the second electric machine to compensate for an existing power deficit or a power excess relative to an external power demand.


A method and apparatus for controlling traction of a vehicle with independent drives or motors connected to the wheels or other ground engaging apparatuses. Nominal torque allocations can be determined for a set of motors, the motors connected to ground engaging elements and including a front set of motors and a rear set of motors. The nominal torque allocations can be modified based on a lateral differential correction and a fore-aft differential correction to produce modified torque commands and the modified torque commands can be applied to the set of motors.


An agricultural harvesting machine comprises an exchangeable crop processing element, which is installed in the interior of the harvesting machine and which is available in different variants, an electronic control unit, which is connected with a data bank in which data concerning the crop processing element are stored, and a reading device, which is set up to interact with an identification element placed on the crop processing element and to transmit an output signal to the control device that clearly identifies the crop processing element during or after an incorporation of a crop processing element into the harvesting machine; with the aid of the signal, the control unit updates the data bank.

A baler having a compression system for forming a bale. The baler also has a feed system having a pack mode for accumulating the crop in a pre-compression chamber and a lift mode for conveying the crop to the compression system. The baler also has a sensor arrangement having at least one sensor generating a signal, the at least one sensor being coupled to the feed system. The signal corresponds to a crop load on the feed system. A control unit is configured to receive the signal from the sensor arrangement and initiate the lift mode based on at least the signal.

A crop sensing system for a baler includes a compression system for forming a bale and a feed system for picking up crop from a surface and conveying the crop to the compression system. The crop sensing system includes a sensor arrangement having at least one sensor being coupled to at least one of the compression system or the feed system, wherein the at least one sensor generates a signal corresponding to a crop load on the at least one of the compression system or the feed system. The crop sensing system includes a control unit configured to receive the signal from the sensor arrangement and calculate crop mass data based on at least the signal.
