A shovel includes a traveling body, a turning body mounted on the traveling body, a work attachment including a boom attached to the turning body, an arm attached to an end of the boom, and an end attachment attached to an end of the arm, and a processor coupled to a memory storing instructions and configured to read and execute the instructions stored in the memory to control a turning operation of the turning body in accordance with a predetermined operation of the work attachment to cause the end attachment to perform the predetermined operation as seen in a plan view in response to an operation by an operator.

A system for controlling implement orientation of a work vehicle includes a computing system configured to control an operation of a lift actuator of the vehicle such that an implement of the vehicle is moved from a first vertical position relative to a second vertical position. Furthermore, the computing system is configured to monitor the angle of the implement as the implement is moved from the first vertical position to the second vertical position. Additionally, the computing system is configured to determine an actual error value between the monitored angle and a selected angle of the implement. Moreover, the computing system is configured to determine a modified error value that is different than the actual error value and control an operation of a tilt actuator of the vehicle to adjust the angle of the implement relative to the driving surface based on the modified error value.

A method of moving material, using a first machine, from a first location to a second location, the second location being a dump bed of a second machine. The method includes determining, by a controller of the first machine, a type of a material to be moved, sending, by the controller of the first machine, the material type to a controller of the second machine, determining, by a controller of the second machine, a load distribution on the dump bed based on the material, determining, by the controller of the second machine, a first position of the dump bed at which a first dump should be unloaded from the first machine, and sending, by the controller of the second machine, an identification of the first position to the controller of the first machine.

An adjustable ride control circuit and method that includes a head valve that controls flow between a boom cylinder head intake and an accumulator, and a rod float valve that controls flow between a boom cylinder rod intake and tank, where the rod float valve is electronically adjustable and proportionally controls flow restriction. A controller controls ride control activation, and adjustment of the head and rod float valves. When ride control is activated, the head valve allows flow between the head intake and the accumulator, and the controller automatically adjusts the rod float valve. When ride control is deactivated, the head valve blocks flow between the head intake and the accumulator, and the rod float valve blocks flow between the rod intake and tank. An enable valve can control positioning of the head valve. A flow selector can select manual or automatic adjustment of the rod float valve.

A system includes a machine position sensor and a controller. The machine position sensor outputs current position data indicative of the position of the work machine. The controller acquires actual topography data including the position of a first slot extending in a predetermined work direction, the position of a second slot positioned beside the first slot, and the position of a first excavation wall positioned between the first slot and the second slot. The controller determines a first excavation path extending from the first slot to a first position on the second slot and cuts across the first excavation wall. The controller determines a transportation path extending from a position behind the first position in the work direction, along the second slot, and toward a predetermined soil unloading position. The controller controls the work machine to move according to the first excavation path and the transportation path.

A method for automated or automatic loading of a work tool of a work machine includes determining, as a function of operating conditions of the work machine, a probability of whether the work tool comes into or is in engagement with a material pile, and activating, in response to the determined probability being greater than a limit value, a load function for the automated or automatic loading. The method further includes ascertaining, when the load function is activated, a setpoint value for a lift position, a setpoint value for a tilt position, and a setpoint value for an accelerator pedal actuation as a function of a pressure measurement value on a hydrostat side of a power split transmission of the work machine, and ascertaining actuating signals for the automated or automatic loading as a function of a comparison of the ascertained setpoint values with corresponding actual values.

A work equipment control device of a work vehicle includes state determination unit and an automatic dump determination unit. The state determination unit determines a work state of the work vehicle based on a traction force of the work vehicle and a posture of work equipment. An automatic dump determination unit determines an automatic dump availability mode indicating the availability in performing automatic dump control for automatically driving a bucket to a predetermined dump angle, in accordance with the work state.

A pitch angle acquisition unit is configured to acquire a pitch angle of a vehicle body. A blade position calculation unit is configured to calculate a position of a blade with reference to the vehicle body. A traveling direction specification unit is configured to specify a traveling direction of the vehicle body based on the pitch angle and the position of the blade.

A controller may obtain, from one or more first devices of a first machine, first information regarding a load associated with a first portion of an object. The first portion, of the object, may be carried by an implement of the first machine and a second portion, of the object, may be carried by an implement of a second machine. The controller may obtain, from one or more second devices of the first machine, second information regarding an orientation of the first machine. The controller may determine, based on the first information and a threshold derived based on the second information, that a load drop condition is satisfied; perform a first action associated with dropping the load; and transmit, to the second machine, information regarding the first action to cause the second machine to perform a second action.

A dozer blade attachment control system for a work machine comprises a dozer blade attachment coupled to the attachment coupler, a hydraulic circuit, and an electronic controller. The hydraulic circuit comprises a hydraulic pump, a diverter valve operable in a first position and second position, and a pressure compensated directional control valve. The electronic controller is communicatively coupled to the hydraulic circuit. The electronic circuit may modify the hydraulic circuit to one or more of a first configuration with the diverter valve in the first position for tilt, a second configuration with the diverter valve in the second position for angling, and a third configuration with the diverter valve in the second position and the pressure compensated directional control valve creating a shuttle flow path from a higher and a lower side of the hydraulic circuit for simultaneously tilting and angling.
