Abstract: A system for controlling slip of vehicle drive members is disclosed. The system includes a power train including a plurality of drive members and a hydraulic transmission configured to supply torque to at least one of the drive members. A magnitude of the torque is related to fluid flow in the hydraulic transmission. The system further includes a controller configured to control the fluid flow in the hydraulic transmission. The controller is configured to receive a signal indicative of a steering command and a signal indicative of a parameter related to pressure in the hydraulic transmission. The controller is further configured to control slip of the at least one drive member based on the signal indicative of a steering command and the signal indicative of a parameter related to pressure.

Abstract: A powertrain arrangement for selectively operating a vehicle in a skid-steer configuration is provided. The arrangement includes an engine coupled to a differential. A first torque transfer mechanism is coupled to a coupling mechanism and arranged to drive a first set of wheels on a side of the vehicle orientated parallel to a wheelbase of the vehicle. A second torque transfer mechanism is coupled to the differential and arranged to drive a second set of wheels on an opposite side of the vehicle. The coupling mechanism is coupled to the differential and includes a rotation selector arranged to selectively engage an output of the differential to provide a torque input to the first torque transfer mechanism of a direction so as to drive the first set of wheels in one of a same and an opposite direction as the second set of wheels.
