Abstract
A method includes determining a delivery rate of paving material being delivered from a paving material plant to a worksite, and determining a plurality of paving machine speeds, wherein at least one speed of the plurality of paving machine speeds is determined based on the delivery rate. The method also includes determining a desired paving machine speed based on a lowest speed of the plurality of paving machine speeds, and causing a paving machine to travel at the desired paving machine speed while depositing paving material on a work surface of the worksite.
Claims20
A method, comprising:
- determining, with a controller, a delivery rate of paving material being delivered from a paving material plant to a worksite remote from the paving material plant;
- determining, with the controller, a plurality of paving machine speeds, wherein at least one speed of the plurality of paving machine speeds is determined based on the delivery rate;
- determining, with the controller, a desired paving machine speed based on a lowest speed of the plurality of paving machine speeds;
- and
- causing a paving machine, disposed at the worksite, to travel at the desired paving machine speed while depositing paving material on a work surface of the worksite.
2 more elements
A paving system, comprising:
- a haul truck configured to transport paving material from a paving material plant to a worksite;
- a location sensor configured to determine a location of the haul truck;
- a paving machine disposed at the worksite and configured to receive paving material from the haul truck;
- a compaction machine following the paving machine at the worksite;
- and
- a system controller in communication with the location sensor via a network, the system controller being configured to:
- receive a signal from the location sensor, the signal including information indicating a location of the haul truck determined by the location sensor,
- determine, based on the signal, a delivery rate of paving material being delivered from the paving material plant to the worksite by the haul truck,
- determine a plurality of paving machine speeds, wherein a first speed of the plurality of paving machine speeds is determined based on the delivery rate, a second speed of the plurality of paving machine speeds is determined based on a maximum compaction rate of the compaction machine, and a third speed of the plurality of paving machine speeds is determined based on a current paving material production rate of the paving material plant and corresponding to the worksite,
- determine a desired paving machine speed based on a lowest speed of the plurality of paving machine speeds, and
- provide the desired paving machine speed to a paving machine controller via the network, the paving machine controller being configured to cause the paving machine to travel at the desired paving machine speed while depositing paving material on a work surface of the worksite.

A control system, comprising:
- a location sensor configured to determine a location of a haul truck;
- a paving machine controller disposed on a paving machine located at a worksite;
- a system controller;
- and
- a network configured to transmit signals between the location sensor, the paving machine controller, and the system controller, wherein the system controller is configured to:
- receive a signal from the location sensor and via the network, the signal including information indicating a location of the haul truck determined by the location sensor,
- determine, based on the signal, a delivery rate of paving material being delivered from a paving material plant to the worksite by the haul truck,
- determine a plurality of paving machine speeds, wherein at least one speed of the plurality of paving machine speeds is determined based on the delivery rate,
- determine a desired paving machine speed based on a lowest speed of the plurality of paving machine speeds, and
- provide the desired paving machine speed to the paving machine controller via the network, the paving machine controller being configured to cause the paving machine to travel at the desired paving machine speed while depositing paving material on a work surface of the worksite.
