統合された全地球的航法衛星システム・センサおよび慣性センサを有する自動ブレード制御システム
Document Type and Number:
Japanese Patent JP5466159
Kind Code:
B2
Abstract:
Disclosed are method and apparatus for controlling the blade elevation and blade slope angle of a dozer blade. Elevation and slope angle measurements are calculated from measurements received from a global navigation satellite system (GNSS) antenna and an inertial measurement unit mounted on the dozer blade. The inertial measurement unit includes three orthogonally placed accelerometers and three orthogonally placed rate gyros. The measurements are processed by algorithms to calculate estimates of the blade elevation, blade vertical velocity, blade slope angle, and blade slope angular velocity. These estimates are then provided as inputs to a control algorithm which provides control signals to control a dozer hydraulic system which controls the blade elevation and blade slope angle.
