    摘要: A loader of the type controlled with an electronic digital controller is disclosed herein. The loader may include conventional mechanical components. However, the hydraulic valve is electronically controlled to provide improved motion control. In particular, the operator controls the loader with a two-axis joystick. When the joystick is moved left or right, the bucket is rolled at a speed proportional to the rate of change of the joystick position and independent of the loader arms. When the joystick is moved forward or backwards, the loader arms of the bucket are raised or lowered. When the joystick is only moved forward or backward with substantially no component of motion left or right, the controller rolls the bucket to maintain a substantially constant angle between the bucket and the loader's frame. This constant attitude control decreases the operator workload and increases control accuracy. The controller provides velocity-based control over the loader arm and bucket motion, or flow-based control for improved stability and accuracy. The controller can monitor available flow and can then limit the commanded flows to the actuators to avoid exceeding the available flow.

    摘要: An automatic guidance system for an agricultural vehicle includes a tractor, a towed implement, an absolute tractor position sensor, a relative implement position sensor, and an electronic control system. The operator inputs the implement geometry and field information into the control system. The control system combines this data with the absolute vehicle position and relative implement position to accurately guide the towed implement through a field.

    摘要: A method for calculating spiral swath paths in an area with irregular boundaries and providing automatic guidance of a vehicle along the calculated spiral swath paths. A baseline swath path is generated, and at least one adjacent swath path is calculated based on the minimum turning radius of the vehicle and associated implement. An algorithm calculates the continuous spiral swath path by monitoring a position data points at the end point of the previous swath path at the starting point of the at least one adjacent swath path, configuring a radius of curvature for each individual swath path determining the radius of curvature for each swath path and joining the individual swath paths into one continuous spiral swath path.
