A control system for a work vehicle includes an acceleration detection device and a controller. The acceleration detection device detects an acceleration of the work vehicle. The controller determines whether the acceleration is greater than a first threshold and reduces the a vehicle speed when the acceleration continues to be equal to or greater than the first threshold over a predetermined first determination time period.

SYSTEM AND METHOD FOR CONTROLLING TRANSPORT VEHICLE

A controller acquires a static path indicative of a target route of a transport vehicle. The static path includes a first endpoint and a second endpoint. The static path is set between a first work machine and a second work machine. The controller determines a first dynamic path that connects the first endpoint and a first target position for work of the first work machine. The controller determines a second dynamic path that connects the second endpoint and a second target position for work of the second work machine. The controller controls the transport vehicle so that the transport vehicle travels according to the static path, the first dynamic path, and the second dynamic path.

11549235 · 2023-01-10 · ·

A system to control operation of a machine having a ground-engaging work implement for moving material about a worksite include a controller configured to determine a feasible target profile for the work implement to engage material. The feasible target profile may include a preload segment, a cut segment, and a loading segment. The controller determines a feasible prospective cut segment from a plurality of prospective cut segments. The controller generates a prospective preloading segment and a prospective loading segment associated with the feasible prospective cut profile. Position points associated with the loading segment are extracted and the controller determines if the ground-engaging work implement will align with the plurality of position points. The controller may also determine whether the load volume for the prospective cut segment is efficient.
