Abstract
A system for regulating wheel slippage of a vehicle carrying or trailing an implement. The system includes sensors for sensing the vehicle's apparent speed and ground speed and an input device. The system also includes a control circuit configured to generate a slip signal based at least upon the apparent speed and the ground speed, and to generate a control signal applied to an actuator for moving the implement. The input device can be manipulated to enable and disable slip regulation and to set a slip reference value. The input device can be manipulated to derive the slip reference value from the slip signal, and to increment and decrement the slip reference value. The control circuit regulates wheel slippage by modifying the control signal when the slip signal exceeds the slip reference value with slip regulation enabled. Also, in a vehicle coupled to an implement, an input device can be manipulated to derive a parameter reference value from an operating parameter, and to increment and decrement the parameter reference value based upon further manipulation of the input device, and a control circuit generates a control signal for moving the implement based upon the difference bet…
