Abstract: Described herein are methods and systems for controlling differential wheel speeds of multi-independent-wheel vehicles, such as four-wheel-drive electric tractors (4WD-ETs). Specifically, a method comprises determining a target speed for each wheel of the vehicle based on at least the steering input. The linear travel speeds (corresponding to these target speeds) of any two wheels are different when the vehicle turns (steering input deviates from a no-steering baseline) or the same when the vehicle travels in a straight line (steering input is at the no-steering baseline). Each target wheel speed is then used to control the rotational speed of the corresponding electric motor, which independently drives one of the vehicle's wheels. This process of determining the target wheel speeds and independently controlling all electric motors is frequently repeated such that the vehicle can be propelled through the turn at the desired speed with minimal wheel slip.

Abstract: In a power steering system employing an end of travel system including valve actuating rings disposed about a Pitman arm shaft, a device is provided for setting the positions of the rings on the shaft. The device includes a fixed member positioned about, and fixed against movement along, a longitudinal axis perpendicular to the shaft's rotational axis and a movable member that moves along the longitudinal axis relative to the fixed member. The movable member defines a pin at one end configured for engagement with the circumferential ends of the actuating rings. A positioning force applied to one of the members causes the movable member to move between set and reset positions in which the pin engages corresponding ends of the actuating rings during rotation of the shaft and a running position in which the pin remains disengaged from the ends of the actuating ring during rotation of the shaft.
