摘要： The position of the blade of a motor grader is controlled to maintain a smoothly graded surface even when the grader's front wheels travel over undulating ungraded ground. This is accomplished by sensing the degree to which the grader frame pivots with respect to the rear wheels and employing the pivot angle to derive the resultant change in blade position. That change is used to operate a mechanism that produces movement of the blade relative to the earth thereby compensating for effects of the pivoting action.

摘要： At least two crawler tracks (T1-T4) or four wheels or rail bogies are provided for transporting and elevating the frame of a mobile machine having a reference side (R) and a cross slope side (Cs). Two jacking points (C1-C2) are located on the reference side and two jacking points (C3-C4) are located on the cross slope side. The reference side (R) tracks a reference in elevation (W) and adapts a desired reference attitude. An attitude sensor (AR) on the reference side measures the actual attitude of the reference side relative to gravity. Likewise, an attitude sensor (ACS) on the cross slope side measures the actual attitude of the cross slope side relative to gravity. The attitude of the cross slope side is adjusted to match the attitude of the reference side. Finally, a single cross slope sensor (ABC) varies the elevation of the cross slope side relative to the reference side.

摘要： A method and apparatus are disclosed for controlling the cross slope angle cut by the blade (114) of an articulated frame motorgrader (100) operated in the crabbed steering mode wherein the articulation angle (A) of the motorgrader frame is sensed and used to calculate the blade angle relative to horizontal required to maintain a desired cross slope angle. The blade angle is sensed and controlled such that the sensed blade angle is maintained substantially equal to the calculated blade angle. The blade angle calculation is performed using the equation: tan B = (sin (A+R))(tan L) + (cos (A+R))(tan C) where B is the required blade slope angle of the blade (114) relative to horizontal; A is the sensed angle of rotation of a steering unit (106) relative to a drive unit (102), the steering unit (106) and drive unit (102) making up the motorgrader (100) articulated frame; R is the sensed angle of rotation of the blade (114) relative to the steering unit (106); L is the sensed direction of travel slope angle of the motorgrader (100); and, C is the desired cross slope angle which is entered by an operator of the motorgrader (100).

摘要： A rotary broom attachment (2) (Figure 1), for a motor graderwhich has a mold board (4) and means (8)to adjust the mold board for vertical elevation, side shift, and rotary position about vertical and horizontal axes, is mounted behind and parallel to the mold board and has independent adjustment and control means (28, 29) for side shift and vertical positioning of the broom relative to the mold board. Sensors are used to signal automatic shifting of the broom vertically or in side shift to avoid interference with the motor grader structure as well as obstacles in the path of the broom. The downward pressure of the broom is controlled by the proportional lift applied thereto by a hydraulic lift means.

摘要： Automatic height control of a dozer blade, the input from the slow absolute height sensor is combined with an input from a gyroscope that measures the instant rotation and recalculates it into a vertical height change using the length of the supporting arms. The combination obtains the accuracy of the absolute height information and an increased speed of measurement resulting in a compensated height estimate that is input to a hydraulic control system of the feedback type. This enables much more aggressive control even though the hydraulic system has an unknown linearity and delay associated with it. The gyroscopic sensor forms an IMU with one degree of freedom to compensate for drawbacks of the absolute height sensor with regard to delay, noise and update rate to obtain a frequent, time-correct height position with a reduced level of noise by means of a calculation based on both types of sensor output.

摘要： 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.

摘要： 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.

摘要： A blade 50 of a work vehicle 10 is coupled to the forward ends of right and left push-beams 32, 34 of a push frame 30 for having the blade pitch adjusted about a transverse axis 66 defined by pivotal connections of the blade 50 with the push-beams 32, 34; and right and left push-beam cylinders 68, 70 are provided between the push-beams 32, 34 and blade 50 for effecting pitch adjustments and for effecting tilt adjustments of the blade 50 about a longitudinal axis 80 located midway between the push-beams 32, 34. The push frame 30 is mounted for pivoting vertically about a second transverse axis 40 so as to adjust the height of the blade 50, with a pair of lift cylinders 82 being coupled between the work vehicle 10 and the blade 50 for effecting this adjustment. An electro-hydraulic control system 100 including an electronic controller 130 is provided for effecting individual or simultaneous control of the push-beam cylinders 68, 70 for effecting blade tilt and pitch adjustments in accordance with operator inputs, with position feedback being provided by cylinder position sensors 140, 142, 144, 146.
