A work vehicle includes a hydraulic actuator that changes an actual steering angle, an actual steering angle detecting part, an operating unit that performs a steering operation, a position adjusting control part that controls the position adjusting part based on the actual steering angle, and a steering control part that controls the hydraulic actuator. The operating unit includes a support part, a rotating part supported rotatably by the support part, an operating part supported rotatably by the support part or the rotating part, a biasing part that biases the operating part to a predetermined position with respect to the rotating part, a position adjusting part that adjusts a rotation angle of the rotating part with respect to the support part, and a rotation angle detecting part configured to detect the rotation angle of the operating part with respect to the support part or the rotating part.

Steering a vehicle in an electronic steering mode of operation that includes a front axle steering system, a rear axle steering system, one or more vehicle environment sensors, and a controller operatively coupled with the front axle steering system, the rear axle steering system, and the vehicle environment sensors. Commanding the vehicle to operate at a desired vehicle speed, detecting a lateral force acting on the vehicle in response to input from the vehicle environment sensors, and determining an actual lateral acceleration of the vehicle and a predicted lateral acceleration of the vehicle from the desired vehicle speed. Determining a lateral acceleration error by comparing the predicted lateral acceleration to the actual lateral acceleration, and determining if the lateral acceleration error exceeds a lateral acceleration limit, then turning both of the front axle steering system and the rear axle steering system to a crab steering correction angle.

The articulated self-propelled work machine (1), such as, for example, an articulated telescopic handler or the like, comprises: a front frame (11), provided with a pair of front wheels (111); a lift arm (2), adapted to support a load, hinged to the front frame (11) and mobile with respect thereto by means of at least one actuator (21, 22); a rear frame (12), provided with a pair of rear wheels (121) and articulated to the front frame (11); detecting means (51, 53, 54) for detecting an angular parameter relative to a steering angle between the front frame (11) and the rear frame (12); and electronic processing means (6) configured to control the operation of the actuator (21, 22) on the basis of the angular parameter.

Systems and methods for vehicle controllers for agricultural and industrial applications are described. For example, a method includes receiving image data, captured using one or more image sensors connected to a vehicle, depicting one or more plants in a vicinity of the vehicle; detecting the one or more plants based on the image data; responsive to detecting the one or more plants, adjusting implement control data; and controlling, based on the adjusted implement control data, an implement connected to the vehicle to perform an operation on the one or more plants.

Disclosed embodiments include steering circuits utilizing a controllable cross-feed loop between left and right drive motor sides of an articulated power machine to reduce skidding caused by a turning operation in which an articulation actuator changes an articulation joint angle between a front frame member and a rear frame member of the power machine.
