A loader vehicle including a frame system, a plurality of wheels, a plurality of drive units and a controller. The plurality of wheels are subject to rapidly changing loads and are associated with the frame system. The plurality of drive units are each associated with a corresponding subset of at least one of the plurality of wheels. The controller is configured to compute a slip error for one of the plurality of wheels dependent on an integral term derived from a wheel speed of at least one other of the plurality of wheels. The controller computes a slip target value for the one wheel. The controller further uses the slip error and the slip target value to arrive at a command that is applied to the drive unit corresponding to the one wheel.
A loader vehicle, comprising:
A drive system for a loader vehicle having right and left front wheels and right and left rear wheels a plurality of wheels, the drive system, comprising:
A method of applying torque to ground engaging wheels of a loader vehicle including a front pair of right and left wheels mounted to a front frame section for individual rotation about a first transverse axis, a rear pair of right and left wheels mounted to a rear frame section for individual rotation about a second transverse axis, and said front and rear frame sections being coupled together for selected articulation relative to each other about an upright axis, comprising the steps of:
