Path planner and method for planning a contour path of a vehicle
First Claim
1. A method for planning a path of a vehicle, the method comprising:
- defining a reference row having a reference contour in a work area;
establishing a representation of the defined reference row, the reference row comprising at least one of a generally curved component and a generally linear component; and
generating one or more contour rows with a tracking contour that tracks or mirrors the reference contour based on a vehicular width and a radius difference parameter associated with the curved component;
the contour rows generated by a translation technique for the generally linear component and a radius modification technique for the curved component.

Abstract
In accordance with one embodiment of the invention, a path planner and method for planning a path of a vehicle defines a reference row having a reference contour in a work area. A representation of the defined reference row is established. The defined reference row comprises a curved component, a generally linear component, or both. A generator generates one or more contour rows with a tracking contour that tracks or mirrors the reference contour based on a vehicular width and a radius difference parameter associated with the curved component. The contour rows are generated by a translation technique for the generally linear component and a radius modification technique for the curved component.
