AUTOMATIC STEERING OF VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17804462 titled 'AUTOMATIC STEERING OF VEHICLE

Simplified Explanation

The patent application describes a method for automatically turning an autonomous mining truck (AMT) in an operating area.

  • The method involves retrieving boundary data associated with the operating area and using this data, along with the dimensions of the AMT, to determine a first path for the turn maneuver.
  • The first path consists of a number of legs that the AMT needs to follow to complete the turn maneuver.
  • The method also includes completing the first leg of the turn maneuver.
  • If the AMT is unable to execute the first path, the method determines a second path and the number of legs necessary to complete the turn maneuver.
  • Finally, the AMT executes the second path to successfully complete the turn maneuver.


Original Abstract Submitted

A method of automatically turning an autonomous mining truck (AMT), including front wheels and rear wheels, around in an operating area, including retrieving boundary data associated with the operating area, determining a first path to follow to execute a turn maneuver within the operating area based at least on the boundary data and dimensions of the AMT, wherein the first path includes a number of legs necessary to follow the first path through the turn maneuver, completing a first leg of the turn maneuver, determining a second path to follow and number of legs necessary to execute the turn maneuver based on an inability to execute the first path, and executing the second path to complete the turn maneuver.
