Abstract
A controller acquires current position data indicative of a current position of a work machine. The controller acquires an inclination angle of an actual topography to be dug. The controller acquires a maximum climbing angle when the work machine travels in reverse. The controller determines a digging angle with respect to the actual topography based on the inclination angle and the maximum climbing angle. The controller determines a target digging trajectory based on the digging angle. The controller controls a work implement according to the target digging trajectory.
