    摘要: An estimate of the relative attitude between an implement and a vehicle body is computed from a body angular velocity measurement received from at least one body gyro mounted on the vehicle body and from an implement angular velocity measurement received from at least one implement gyro mounted on the implement. A first system state vector estimate corresponding to a first time instant includes a representation of a first relative attitude estimate. An updated system state vector is computed based at least in part on the first system state vector estimate, the body angular velocity vector measurement, and the implement angular velocity vector measurement. A second system state vector estimate corresponding to a second time instant is predicted based at least in part on the updated system state vector and a time-dependent system model. The second system state vector estimate includes a representation of a second relative attitude estimate.

    摘要: Disclosed is a method for mapping network identifiers to a set of sensor modules that measure a three-dimensional action vector and that are sensitive to orientation in three-dimensional space. Each sensor module is mounted at a different position on a machine such that the orientation of each sensor module is different. The method includes one or two stages. In the first stage, the machine is placed in a stationary state, and measurements of a static action vector from a sensor module identified by a network identifier are correlated with expected measurements from a sensor module having a corresponding orientation and corresponding position. In the second stage, the machine is placed in a dynamic state, and measurements of a dynamic action vector from a sensor module identified by a network identifier are correlated with expected measurements from a sensor module having a corresponding orientation and corresponding position.

    摘要: An earthmoving system (100) includes a laser transmitter (102) for transmitting a reference beam of laser light, and a bulldozer (106) having a laser receiver (126) mounted on the bulldozer for sensing the laser light. The earthmoving system further includes a frame (108) and a cutting blade (110) supported by a blade support (112) extending from the frame. The blade support has a pair of hydraulic cylinders (114.114) for raising and lowering the blade in relation to the frame. A gyroscopic position sensor (136) senses rotation of the frame about an axis generally transverse to the bulldozer and passing through the center of gravity (134) of the bulldozer. The control (140) is responsive to the laser receiver and to the gyroscopic orientation sensor, and controls the operation of the cylinders and the position of the cutting blade.

    摘要: The invention relates to a computer program product for deriving a heading (512) of an implement (2) of a work vehicle (1). The work vehicle (1) comprises, as independently tracked components, the implement (2), a chassis (4) and an arm (3) connecting the two. For each of the independently tracked components, a respective IMU (52-57) is correspondingly associated, wherein the IMU provides an IMU reference frame of the component representing a measured pose of said component. The computer program product derives, on the basis of the IMU reference frames, internal and external constraints consistent component reference frames. The heading (512) of the implement is derived utilizing the consistent component reference frames.

    摘要: An implement having an implement acceleration is operably coupled to a vehicle body having a body acceleration. An attitude of the implement is estimated by receiving acceleration measurements from an accelerometer mounted on the vehicle body and an accelerometer mounted on the implement. A state vector estimate is calculated based at least in part on the body acceleration measurement and the implement acceleration measurement. The state vector estimate includes a representation of the attitude of the implement relative to the vehicle body. In addition to the accelerometer measurements, angular velocity measurements can be received from a gyro mounted on the vehicle body and a gyro mounted on the implement. The state vector estimate is then calculated based at least in part on the body acceleration measurement, the implement acceleration measurement, the body angular velocity measurement, and the implement angular velocity measurement.

    摘要: Known systems for automatic height control of a dozer blade (302), which rotates about a line through pivot points (304) for supporting arms (303) when it changes its height use feedback and a reference from an absolute blade height measuring system (306). This only permits a slow operation. According to the invention the input from the slow absolute height sensor (306) is combined with an input from a fast gyroscope (307 or 308) that measures the instant rotation and recalculates it into a vertical height change using the length (309) of the supporting arms as the basis. The combination obtains the accuracy of the infrequent 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 improved height feedback 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 (307 or 308) with one degree of freedom to compensate for the inevitable drawbacks of the absolute height sensor (306) in use 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.
