摘要： Control method for actuating a loader (WL) comprising an arm (B) to which a bucket (BK) is connected, the method comprising in cyclic execution checks (FB) that a first mono-stable button is depressed, if it is depressed, then execution (Sequence) of the following sequence of operations: unloading, shaking, returning to dig position or if the vehicle is equipped with a 4 in 1 shovel: unloading, 4 in 1 shovel opening, shaking, 4 in 1 shovel closing, returning to dig position, otherwise if the first button (FB) is released then stop (STOP) of the execution of the sequence.

摘要： A method of steering an articulated wheel loader including a front body portion and a rear body portion, the front body portion including a bucket and a pair of front wheels. The rear body portion is pivotally coupled to the front body portion and includes a pair of rear wheels. The method includes steps of: providing a steering command to steer the wheel loader; detecting an angle that a front longitudinal axis of the front body portion forms with a rear longitudinal axis of the rear body portion; and when the detected angle is greater than a threshold automatically implementing a steering brake function to independently brake one of the pair of front wheels or rear wheels that is on a steering side to reduce a speed of the braked wheel to zero so that the braked wheel becomes a pivot point to minimize a turning radius.

摘要： A method for actuating the movement of a boom, or an attachment, in a work vehicle includes determining a joystick position difference between the actual component of the position of the joystick along a boom, or attachment, actuation axis in a first time instant and a neutral position of the joystick along the boom, or attachment, actuation axis, determining a first position of the boom, or attachment, along the boom travel path in the first time instant, and a second position of the boom, or attachment, along the boom travel path in a second time instant, and determining a boom, or attachment, position difference between the second position and the first position. If the determined boom, or attachment, position difference is lower than a threshold and the determined joystick position difference is higher than a joystick position difference threshold, the method also includes slowing movement of the boom, or attachment.

摘要： Method for detecting a work or agricultural vehicle mission through a neural network, wherein the vehicle is provided with an arm including at least two elements wherein one first element is connected to a vehicle frame and one second element is connected to the first element and means to detect a reciprocal degree of freedom between the first element and the frame and between the second element and first element such to assume a plurality of operation configurations, the method including, within an observation time interval, the monitoring of the arm in order detect frequency and time duration for each operation configurations and detecting the vehicle mission as a function of the balance of said frequencies and time durations.

摘要： A method for executing straight tracking control may include receiving an input command(s) associated with controlling the operation of a first-side drive system and/or a second-side drive system of a hydrostatic transmission of a work vehicle to drive the vehicle along a straight path. The method may also include receiving first and second speed signals associated with the output speeds of the drive systems, and modifying the first speed signal or the second speed signal based on a speed scaling factor to generate a corrected speed signal. In addition, the method may include determining an adjusted control command for controlling the operation of the hydrostatic transmission as a function of the input command(s) and a control output determined based on the corrected speed signal. Further, the method may include controlling the operation of the hydrostatic transmission based at least in part on the adjusted control command.
