Abstract: A vehicle row follow system may include a vehicle comprising at least one sensor to output signals serving as a basis for a three-dimensional (3D) point cloud and to output signals corresponding to a two-dimensional (2D) image of a region forward the vehicle. The system may further include a non-transitory computer readable medium containing instructions to direct a processor to: determine plan row lines in a 2D image; determine a yaw of the vehicle based upon a slope of a heading line relative to a centerline between the plant row lines in the 2D image; determine a lateral offset of the vehicle from the centerline between the consecutive plant rows based upon an identity of the consecutive plant rows in the 3D point cloud; and output steering control signals based upon the determined yaw and lateral offset of the vehicle.

The variable speed front drive system may include a hydraulic pump, a hydraulic motor driven by the hydraulic pump and operably coupled to the front ground traction members by a planetary gear assembly. The planetary gear assembly may include a sun gear coupled to and driven by the hydraulic motor, a ring gear operably coupled to the rear ground traction members and a planet carrier carrying planet gears intermeshing between the ring gear and the sun gear. The planet carrier has an output shaft operably coupled to the front ground traction members. At least one sun brake is actuatable by the controller to retard rotation of the sun gear.

Abstract: A vehicle may include rear ground traction members, front ground traction members, a rear drive system to drive the rear ground traction members, a continuously variable speed front drive system to drive the front ground traction members, a rear speed sensor to output rear speeds of the rear ground traction members, a front speed sensor to output front speeds of the front ground traction members, and a controller to select a chosen lead for a rear speed of the rear ground traction members based on evaluations of different tractive efficiencies for different leads for the rear speed. The controller may further output control signals to the continuously variable speed front drive system to drive the front ground traction members at the chosen lead.

Abstract: A vehicle is operable in a first mode in which vehicle actions are controlled in response to inputs received by an input device carried by the vehicle from an operator while being boarded on the vehicle and in a second mode in which vehicle actions are controlled in response to inputs received from the operator while the operator is proximate the vehicle, but no longer boarded on the vehicle. The vehicle carries a sensor configured to output a sensed input, as sensed by the sensor, from the operator proximate the vehicle, but not boarded on the vehicle. The sensed input is recognized and associated with a vehicle action and control signals are output to the vehicle based on the sensed input to cause the vehicle to carry out the vehicle action.

Abstract: A vehicle may include rear ground traction members, front ground traction members, a rear drive system to drive the rear ground traction members, a continuously variable speed front drive system to drive the front ground traction members, a rear speed sensor to output rear speeds of the rear ground traction members, a front speed sensor to output front speeds of the front ground traction members, and a controller to select a chosen lead for a rear speed of the rear ground traction members based on evaluations of different tractive efficiencies for different leads for the rear speed. The controller may further output control signals to the continuously variable speed front drive system to drive the front ground traction members at the chosen lead.

Abstract: A tight turn wheel locking system may include a steering end stop sensor to output signals indicating that steered front wheels of a vehicle are in an end stop state towards a short turn side, an end stop steering wheel input sensor to output signals indicating end stop operator input to the steering wheel while the steered front wheels are in the end stop state, and a controller configured to automatically enter a tight turn mode in response to the end stop operator input satisfying a predetermined threshold. The controller, in the tight turn mode, outputs tight turn control signals that cause a vehicle braking system of the vehicle to lock a rear wheel of the vehicle corresponding to the short turn side.

Abstract: A three-point hitch hookup assist system may include a three-point hitch system. The three-point hitch system may include a lower link having a first connection about which the lower link pivots and an implement connector, a powered actuator to pivot the lower link, a first sensor coupled to the lower link to output signals indicating a manual force applied by an operator to the lower link, and a controller. The controller may output control signals to the powered actuator to cause the powered actuator to apply an assist force to the lower link based upon the sensed manual force.

Abstract: A vehicle rollover mitigation system may include at least one first sensor to output rollover symptom signals indicating potential rollover of a vehicle, at least one second sensor to output vehicle environment signals indicating a surrounding environment of the vehicle and a controller to output rollover mitigation control signals for mitigating potential rollover of the vehicle based upon the rollover symptom signals and the vehicle environment signals. The vehicle rollover mitigation system may automatically respond to potential rollover by altering a state of an implement coupled to the vehicle.

Abstract: A vehicle may operate in a first mode in which an electric motor operates in a forward state such that the rear ground traction members of the vehicle are driven forwardly by the electric motor while a hydraulic pump is powered by the electric motor and may alternatively operate in a second mode in which the electric motor operates in a reversed state such that the rear ground traction members are driven forwardly by the electric motor while the electric motor is operably decoupled from the hydraulic pump by a one-way clutch/bearing ring coupled between the electric motor and the hydraulic pump.
