Control mapping for hydraulic machines

A machine control system can store model weights determined via machine learning using a training dataset correlating preset hydraulic valve displacements to measured movement parameters of a machine component. The machine control system can receive an input command for the component and machine state data from machine sensors. A control mapping model can use the model weights to map a combination of the input command and the machine state data into a predicted displacement of the hydraulic valve that causes movement of the component in response to the input command.

A camera captures an image of a region including at least a portion of an operating member and generates image data indicative of the image. A controller acquires the image data from the camera. The controller determines whether an operation of the operating member by an operator is an intentional operation or an unintentional operation based on the image. When the operation of the operating member by the operator is determined to be the intentional operation, the controller controls a work machine according to the operation of the operating member. When the operation of the operating member by the operator is determined to be the unintentional operation, the controller invalidates the operation of the operating member.

A one-handed joystick for excavators allows an operator to make all necessary motions with a single hand and arm for manipulating an excavator tool. The one-handed joystick includes a rotatable cylinder bar, a rotatable ring and an industrial joystick base. The rotatable cylinder bar is grasped with a hand. The industrial base is moved front to back, or right to left. The following are preferable hand/arm motions. A downward hand curl is associated with a bucket digging motion; an upward hand curl is associated with a bucket dump; a forearm forward push is associated with a boom/stick extension; a forearm reward pull is associated with a boom/stick retraction; a left-hand movement is associated with swinging the excavator left; a right-hand movement is associated with swinging the excavator right; a clockwise hand twist is associated with a stick/boom extension; and a counter clockwise hand twist is associated with a stick/boom retraction.

An attachment is attached to an upper turning body. During a normal operation, a drive means drives the attachment according to an input of an operator to a manipulation device. A sensor detects a motion of an excavator. Based on an output of the sensor, the slip suppression unit detects slip of a traveling body in an extension direction of the attachment and corrects an operation of the attachment performed by the drive means.

The hydraulic excavator includes a vehicle body, a work implement , a display section, a detection section , and a display control section. The vehicle body includes a driver’s seat . The work implement is attached to the vehicle body and operates with respect to the vehicle body. The display section is provided on the work implement. The detection section detects an object in a region on a side opposite to the driver’s seat with respect to the work implement around the vehicle body. The display control section displays the information detected by the detection section on the display section.

Excavator

An excavator includes a traveling body, an upper turning body rotatably provided on the traveling body, an attachment which has a boom, an arm, and a bucket and is attached to the upper turning body, and a controller configured to perform a control of a cylinder of at least one shaft of the attachment so as to suppress a vibration of the traveling body or the upper turning body, which is caused by an aerial operation of the attachment.

Work machine

The front pillar disposed on the second side face of the cab is located behind the front pillar disposed on the first side face of the cab. The boom mounting bracket and the front pillar overlap each other in a side view.

Counterweight removal protection system
11542682 · 2023-01-03 · ·

A counterweight removal protection system and a method of controlling removal of the counterweight to avoid damage to an imaging sensor system of a work vehicle, such as an excavator. The imaging sensor system includes an imaging sensor supported by the counterweight and configured to transmit an imaging sensor signal to a vehicle controller to determine the state of the imaging sensor signal. A user interface in the work vehicle includes a selectable touch button to enable removal of the counterweight depending on the state of the imaging sensor signal. An interlock device prevents lowering the counterweight based on the state of the imaging sensor signal. In one embodiment, the imaging sensor signal is a heartbeat signal.
