Document Type and Number:
WIPO Patent Application WO/2023/276528
Kind Code:
A1
Abstract:
In the present invention, a controller acquires current topography data indicating the current topography which is subject to work. The controller acquires target topography data indicating a target topography. The controller controls a lift actuator such that the blade edge of a blade moves in accordance with the target topography. The controller controls a pitch actuator such that the pitch angle of the blade is changed, on the basis of the vertical positional relationship between any two from among the current topography corresponding to the current blade edge position, the target topography corresponding to the current blade edge position, and the current blade edge position.
