System and method for speed-based coordinated control of agricultural vehicles
First Claim
1. A control system for a haul vehicle, comprising:
- a first transceiver configured to receive a signal from a second transceiver, wherein the signal is indicative of a first determined position of a target vehicle and a first determined velocity of the target vehicle; and
a controller communicatively coupled to the first transceiver, wherein the controller is configured to automatically control the speed of the haul vehicle by;
determining a target position of the haul vehicle and a target speed of the haul vehicle based at least in part on the first determined position and the first determined velocity;
determining a first radius of curvature of the target vehicle based at least in part on the first determined position and the first determined velocity;
determining a second radius of curvature of the haul vehicle based at least in part on the first radius of curvature and the target position;
instructing an automated speed control system to establish a ground speed of the haul vehicle to reach the target position; and
instructing the automated speed control system to control the ground speed of the haul vehicle to maintain the target position during docking of the haul vehicle with the target vehicle, while docked, and during turning of both the target vehicle and the haul vehicle, wherein, during turning of both the target vehicle and the haul vehicle, instructing the automated speed control system to control the ground speed of the haul vehicle based at least in part on the first radius of curvature, the second radius of curvature, and the first determined velocity of the target vehicle.

Abstract
A control system for a haul vehicle, includes a first transceiver configured to receive a first signal from a second transceiver, wherein the first signal is indicative of a first determined position and a first determined velocity of the target vehicle. The control system includes a controller communicatively coupled to the first transceiver, wherein the controller automatically controls the speed of the haul vehicle by determining a desired position and a desired speed of the haul vehicle based at least in part on the first determined position and the first determined velocity of the target vehicle, instructing an automated speed control system to establish the ground speed of the haul vehicle to reach the target position, and instructing the automated speed control system to control the ground speed of the haul vehicle to maintain the target position, including during turning of the target and haul vehicles.
