A method for operating a machine's steering system having an input device, and components to manipulate the machine's traction devices based on the input device's actuation, includes detecting a condition of at least one component of the components in response to an actuation of the input device; determining a steering angle of the traction devices corresponding to the condition of the component according to a map table; receiving an input to set the steering angle to an actual steering angle; estimating a difference between the actual steering angle and the steering angle determined according to the map table; modifying the map table by shifting each steering angle of the plurality of steering angles with respect to each condition of the plurality of conditions based on the difference to generate an adjusted map table; and outputting the actual steering angle based on the adjusted map table to correspond to the condition.

A method for steering a gantry crane having wheel assemblies includes the steps of: initiating movement of the gantry crane; and rotating the wheel assemblies wherein the front wheel assemblies rotate in a first rotational direction and the rear wheel assemblies rotate in a second rotational direction. The first rotational direction is opposite to the second rotational direction. First side wheel assemblies rotate at a first rotational speed and second side wheel assemblies rotate at a second rotational speed, such that the gantry crane moves from a linear path to an arcuate path with a turning radius decreasing to substantially zero for rotation about a central axis.

The present invention relates to a control system for use in an agricultural harvester, the system comprising a control panel (10) configured to send at least one mode signal (11) to a control means (20) via an user's (100) command (50), the control means (20) being configured to receive the mode signal (11) and generate a set of instructions (30), the set of instructions (30) being a function of the received mode signal (11), the control means (20) being configured to control at least one piece of equipment from a set of equipment (40) of the agricultural harvester depending on the generated set of instructions (30), providing greater reliability, precision and efficiency in its operation and elimination of operational errors caused by the user.

A motorized personal transport utility vehicle comprises a frame, independent front and rear suspension and a plurality of wheel hubs. Each suspension arm is pivotally coupled to a central frame portion. A pair of front wheel hubs are coupled to the front suspension arms and a pair of rear wheel hubs are coupled to the rear suspension arms. Each of the wheel hubs includes an integrated electric hub motor. The front and rear suspension arms are configured such that the front wheel hub track width is greater than the rear wheel hub track width such that the inner width between the insides of the front wheel hubs is greater than the outer width between the rear wheel hubs.

The roll induces four wheel steering vehicle employs a frame system to protect the driver and serves as an attachment point for, independent suspension links pivotally connect to the wheel assemblies enabling four wheel independent suspensions. A mechanically manipulated centrally mounted steering and suspension pivot, provides both steering control and suspension attachment for the shock and spring. The device is controlled by the driver using typical steering wheel and pedal movement. Steering movement by the driver produces proportionally appropriate camber, steering angle, and roll simultaneously. The invention provides a feeling of integration with the vehicle as the driver rolls into turns with the vehicle, while minimizing fatigue caused by the continuous resistance to centrifugal cornering forces.

Automatic steering and four-wheel steering are configured on an agricultural machine so that when automatic steering is enabled, a control system selectively activates and deactivates four-wheel steering depending on sensed turning or non-turning states of the machine. When automatic steering is enabled, the machine can automatically steer, such as according to a prescription map. In straightaway paths, corresponding to non-turning states, the control system can activate two-wheel steering. However, in the headlands of fields, corresponding to turning states, the control system can activate four-wheel steering. Such turning states can be determined based on the machines location on the map. Alternatively, such turning states can be determined based on sensed turning of the wheels. When an operator takes control of steering, such as by turning the steering wheel, automatic steering can disable, and the control system can activate four-wheel steering, to provide an optimum state for turning in the headlands of fields.
