Abstract
A system for controlling an autonomous construction vehicle includes a controller configured to identify a boundary of a construction site, identify a slope within the boundary of the construction site, determine if the slope exceeds a predetermined threshold value, and create a path plan for an autonomous construction vehicle based on whether the first slope exceeds the threshold value to align the movement of the autonomous construction vehicle with the slope.
Claims20
A method for controlling an autonomous construction vehicle, comprising:
- identifying a boundary of a construction site;
- identifying a first slope of the construction site;
- determining if the first slope exceeds a predetermined threshold value, the predetermined threshold value corresponding to a predetermined maximum side slope value for the autonomous construction vehicle;
- creating, at a controller, a first path plan for the autonomous construction vehicle based on whether the first slope exceeds the threshold value;
- and
- controlling the operation of the autonomous construction vehicle based on the first path plan.
A method for controlling an autonomous construction vehicle, comprising:
- mapping, at a controller, a construction site plan including a worksite boundary;
- accessing, at the controller;
- slope data corresponding to a surface within the worksite boundary;
- mapping, at the controller, a first path plan onto the construction site plan such that a first slope is not a side slope relative to movement of the autonomous construction vehicle;
- and
- wirelessly communicating the construction site plan from the controller to the autonomous construction vehicle.
A system, comprising:
- an autonomous construction vehicle;
- and
- a first controller configured to:
- map a construction site plan including a worksite boundary;
- access slope data corresponding to a surface within the worksite boundary;
- map a first path plan onto the construction site plan such that a first slope that exceeds a predetermined threshold value is not a side slope relative to movement of the autonomous construction vehicle;
- wherein the autonomous construction vehicle is configured to move according to the construction site plan.
