Guided maneuvering of a mining vehicle to a target destination
First Claim
1. A system for navigating a haul truck through a mining environment to a target destination associated with a shovel, the target destination being located within a loading area proximate the shovel, the system comprising:
- a distributed objects database, the distributed objects database storing information describing hazards, boundaries and target destinations within the mining environment;
a position sensor, the position sensor configured to identify a position and an orientation of the haul truck, the position sensor being mounted to the haul truck;
a navigation aid configured to;
retrieve a location of the target destination associated with the shovel from the distributed objects database, wherein the location of the target destination is at least partially determined by a position of the shovel, and at least one of a tail drag radius of the shovel, a corner drag radius of the shovel, and a boom radius of the shovel,calculate a path from a current position of the haul truck to the location of the target destination, the calculated path being selected to avoid hazards within the mining environment,use the position sensor to monitor a progress of the haul truck along the calculated path,identify a performance characteristic of the haul truck, andwhen the haul truck deviates from the calculated path, use the performance characteristic to determine whether the haul truck is capable of returning to the calculated path; and
a user interface configured to display at least a portion of the calculated path to an operator of the haul truck.

Abstract
A system and method for navigating a first heavy equipment to a target destination is provided. A location of the target destination is retrieved from a distributed objects database. The location of the target destination is at least partially determined by a position of a second heavy equipment. A position sensor identifies a current position and orientation of the first heavy equipment, and a path from the current position of the first heavy equipment to the location of the target destination is calculated. The calculated path is selected to avoid hazards. A progress of the first heavy equipment along the calculated path is monitored using the position sensor. When the first heavy equipment deviates from the calculated path, a message is outputted to an operator of at least one of the first heavy equipment and the second heavy equipment.

6. A method for navigating a first heavy equipment to a target destination, the method comprising:
-
retrieving a location of the target destination from a distributed objects database, wherein the location of the target destination is at least partially determined by a position of a second heavy equipment; using a position sensor to identify a current position and orientation of the first heavy equipment; calculating a path from the current position of the first heavy equipment to the location of the target destination, the calculated path being selected to avoid hazards; monitoring a progress of the first heavy equipment along the calculated path using the position sensor; and when the first heavy equipment deviates from the calculated path; identifying a performance characteristic of the first heavy equipment, using the performance characteristic to determine whether the first heavy equipment is capable of returning to the calculated path, and outputting a message to an operator of at least one of the first heavy equipment and the second heavy equipment. - View Dependent Claims (7, 8, 9)
