ROAD PROFILING METHOD FOR MOTOR GRADER Russian patent published in 2019 - IPC E02F3/84 E02F1/00 G05D1/10 

FIELD: road construction.

SUBSTANCE: invention relates to profiling of roadway with motor grader. Method for profiling roadway includes forming vector Ū₃, setting signals of multi-dimensional position control system X_WM, Y_WM, Z_WM mid point of cutting edge and angle β_RO crosswise skew of working member of motor grader in base coordinate system O_bX_bY_bZ_b, measuring coordinates X_WM, Y_WM, Z_WM set of sensors of satellite navigation system, measurement of angle β_WM angle sensor located on the motor grader, determining the deviations of the position of the working member on the coordinates X_WM, Y_WM, Z_WM, β_WM relative to given vector Ū₃, control of position of working member in function of these deviations by means of running and steering devices of motor grader and hydraulic drives of lifting-lowering and warping of working element, periodic measurement of coordinate Z_WM one or more alternative sensors, calculation by developed algorithm of signal Z_K correction, which is used in working member position coordinate control system on Z_WM coordinate.

EFFECT: technical result is higher accuracy of geometrical parameters of erected fabric.
