Document Type and Number:
Japanese Patent JP2022025829
Kind Code:
A
Abstract:
To improve the detection accuracy of equipment used to acquire a position of a blade.SOLUTION: A motor grader 1 comprises an antenna 60 for receiving satellite positioning signals located on a roof 3R of a cab 3, a first IMU 61 mounted on the cab 3, a second IMU 62 mounted on a drawbar 40, a rotation angle sensor to detect the rotation angle of a turning circle 41 relative to the drawbar 40, a tilt angle sensor to detect the tilt angle of a blade 42 relative to the turning circle 41, and a controller. The controller obtains the position of the blade 42 in the global coordinate system based on the satellite positioning signals received by the antenna 60 and the detection results of the first IMU 61, the second IMU 62, the rotation angle sensor and the tilt angle sensor.SELECTED DRAWING: Figure 2
