Abstract
Methods, apparatus, and articles of manufacture to generate a turn path for a vehicle are disclosed. An example apparatus disclosed herein includes input interface circuitry to obtain a guidance path for a vehicle, turn identification circuitry to identify a turn in the guidance path, and turn pattern selection circuitry to select, from a plurality of predetermined turn patterns, a turn pattern for the turn, wherein the turn pattern satisfies a condition.
Claims20
An apparatus comprising:
- interface circuitry;
- machine-readable instructions;
- and
- at least one processor circuit to be programmed by the machine-readable instructions to:
- identify, in a guidance path of a vehicle having an implement coupled thereto, a turn from a first path section to a second path section;
- identify, from a plurality of predetermined turn patterns, first turn patterns that do not include a curved backup path and second turn patterns that include a curved backup path;
- when the implement is pivotable relative to the vehicle, select, from the first turn patterns, a turn pattern for the turn;
- and
- cause steering of the vehicle along the turn based on the selected turn pattern by causing the vehicle to:
- travel forward on a first forward path along the first path section;
- travel rearward on a first rearward path along the first path section;
- travel forward on a curved turn path from the first path section to the second path section;
- travel rearward on a second rearward path along the second path section;
- and
- travel forward on a second forward path along the second path section.

- machine-readable instructions;
- and
- at least one processor circuit to be programmed by the machine-readable instructions to:
- identify, in a guidance path of a vehicle having an implement coupled thereto, a turn from a first path section to a second path section;
- identify, from a plurality of predetermined turn patterns, first turn patterns that do not include a curved backup path and second turn patterns that include a curved backup path;
- when the implement is fixed relative to the vehicle, select, from the second turn patterns, a turn pattern for the turn;
- and
- cause steering of the vehicle along the turn based on the selected turn pattern by causing the vehicle to:
- travel forward on a first forward path along the first path section;
- travel rearward on a curved turn path from the first path section to the second path section;
- and
- travel forward on a second forward path along the second path section.

- identify, from a plurality of predetermined turn patterns, first turn patterns that do not include a curved backup path and second turn patterns that include a curved backup path;
- select, based on whether the implement is fixed or pivotable relative to the vehicle, a turn pattern for the turn from one of the first turn patterns or the second turn patterns;
- and
- cause steering of the vehicle along the turn based on the selected turn pattern by causing the vehicle to:
- travel forward on a first path from a first location to a second location, the first path substantially aligned with and parallel to the first path section;
- travel on a curved turn path from the first path section to the second path section, the curved turn path to be within an area defined between the first location and the second location;
- and
- travel forward on a second path substantially aligned with and parallel to the second path section.
