Automatic Blade Control System during a Period of a Global Navigation Satellite System ...

Номер: US20120059554A1
Автор: Alexander N. Omelchenko, Alexey V. Zhdanov
Принадлежит: Topcon Positioning Systems Inc

For precision grading of terrain by a dozer, the dozer blade can be automatically controlled based on measurements from a combination of a global navigation satellite system real-time kinematic mode (GNSS RTK) system and inertial sensors. At least one GNSS sensor and at least one inertial sensor are mounted on the dozer. Control algorithms are based on blade elevation and blade slope angle. During a period of GNSS RTK system outage, control of blade elevation is not available. Blade control is maintained by switching to control algorithms based on blade slope angle and blade pitch angle. Blade slope angle and blade pitch angle are controlled based on extrapolated target values of blade slope angle and blade pitch angle. The extrapolated target values of the angles are extrapolated from target values of the angles prior to the GNSS RTK system outage with the use of a distance travelled by the dozer.

Automatic Blade Slope Control System

Номер: US20120239258A1
Автор: Hiroyuki Konno, Renard Tomas Graham, Vernon Joseph Brabec
Принадлежит: Topcon Positioning Systems Inc

The slope angle of a blade on an earthmoving machine is automatically controlled based on measurements from a three-axis gyroscope, a blade slope angle tilt sensor, and a blade tip angle tilt sensor mounted on the blade. A three-axis gyroscope has high dynamic response and high resistance to mechanical disturbances but is subject to potentially unbounded errors. A tilt sensor has bounded errors but has a slow dynamic response and a high sensitivity to mechanical disturbances. The combination of a three-axis gyroscope and two tilt sensors provides an advantageous measurement system. Algorithms for performing proper fusion of the measurements account for the lack of synchronization between the three-axis gyroscope and the tilt sensors and also screen out invalid measurements from the tilt sensors. The blade slope angle is controlled based on a reference blade slope angle and an estimate of the blade slope angle computed from properly fused measurements.

Dozers outfitted with manual or electric valves can be retrofitted with a control system for automatically controlling the elevation and orientation of the blade. No modification of the existing hydraulic drive system or existing hydraulic control system is needed. An arm is operably coupled to the existing joystick, whose translation controls the elevation and orientation of the blade. The arm is driven by an electrical motor assembly. Measurement units mounted on the dozer body or blade provide measurements corresponding to the elevation or orientation of the blade. A computational system receives the measurements, compares them to target reference values, and generates control signals. Drivers convert the control signals to electrical drive signals. In response to the electrical drive signals, the electrical motor assembly translates the arm, which, in turn, translates the joystick. If necessary, an operator can override the automatic control system by manually operating the joystick. 1.

In one aspect, a method for creating a final graded soil surface may include controlling an operation of a grading implement of a work vehicle such that the grading implement removes a layer of soil from a current soil surface as the work vehicle is moved in a forward direction. The method may also include receiving an input indicative of the current soil surface being at an offset soil depth relative to the initial ungraded soil surface, with the offset soil depth differing from the final soil depth. When the current soil surface is at the offset soil depth, the method may further include adjusting a position of the grading implement to add or remove soil based on a depth differential defined between the offset soil depth and the final soil depth to create the final graded soil surface as the work vehicle is moved in the reverse direction. 1. A method for creating a final graded soil surface having a final soil depth relative to an initial ungraded soil surface , the method comprising:controlling, with a computing device, an operation of a grading implement of a work vehicle such that the grading implement removes a layer of soil from a current soil surface as the work vehicle is moved in a forward direction, the work vehicle extending longitudinally between a forward end and an aft end, the grading implement being located at the forward end of the work vehicle, the grading implement traversing the current soil surface prior to the aft end of the work vehicle when work vehicle is moved in the forward direction, the aft end of the work vehicle traversing the current soil surface prior to the grading implement when work vehicle is moved in a reverse direction;receiving, with the computing device, an input indicative of the current soil surface being at an offset soil depth relative to the initial ungraded soil surface, the offset soil depth differing from the final soil depth; andwhen the current soil surface is at the offset soil depth, adjusting, with the computing ...

A controller calculates a virtual design surface including a first design surface extending from an excavation start position in a traveling direction of a work vehicle and a second design surface further extending from the first design surface in the traveling direction. The controller generates a command signal that causes the work implement to move along the virtual design surface. The controller changes a position of the first design surface so that the first design surface extends along the current landscape or is located below the current landscape when the first design surface is located above the current landscape.
