Abstract

A physical attribute of a receiving vehicle (a receiving vehicle parameter) is located by calculating a vehicle parameter offset value indicative of the location of the receiving vehicle parameter relative to a reference point on a following vehicle, the following vehicle providing propulsion to the receiving vehicle. The vehicle parameter offset value is stored for access during an unloading operation. A leading vehicle automatically accesses the vehicle parameter offset value and unloads material into the receiving vehicle using the vehicle parameter offset value corresponding to the receiving vehicle.

First claim

What is claimed is:

1 . A method of controlling an unloading operation for unloading material from a leading vehicle into a receiving vehicle that is propelled by a following vehicle, the following vehicle and receiving vehicle comprising a following vehicle/receiving vehicle pair, the method comprising:
detecting a vehicle identifier corresponding to the following vehicle/receiving vehicle pair; obtaining a vehicle parameter offset value corresponding to the vehicle identifier, the vehicle parameter offset value being indicative of a location of a receiving vehicle parameter relative to a following vehicle reference point on the following vehicle,
wherein obtaining the vehicle parameter offset value comprises:
detecting, by a receiving vehicle sensor on the leading vehicle, the receiving vehicle parameter;
determining a relative location of the receiving vehicle parameter, detected by the receiving vehicle sensor, relative to a leading vehicle reference point on the leading vehicle; and
determining the location of the receiving vehicle parameter relative to the following vehicle reference point based on the relative location of the receiving vehicle parameter relative to the leading vehicle reference point on the leading vehicle;

obtaining an indication of a relative position of the following vehicle reference point relative to the leading vehicle; and controlling the unloading operation based on:
the vehicle parameter offset value indicative of the location of the receiving vehicle parameter relative to the following vehicle reference point on the following vehicle, and
the relative position of the following vehicle reference point relative to the leading vehicle.

2 . The method of claim 1 and further comprising:
storing the vehicle parameter offset value on a data store.

3 . The method of claim 1 and further comprising:
sending the vehicle parameter offset value to at least one of:
a remote system, remote from the leading vehicle, for storage on the remote system; or
a different vehicle, different from the leading vehicle.

4 . The method of claim 1 wherein controlling the unloading operation comprises controlling at least one of:
the leading vehicle;
the receiving vehicle; or
the following vehicle.

5 . The method of claim 1 wherein obtaining the vehicle parameter offset value comprises:
performing an automatic calibration operation to obtain the vehicle parameter offset value.

6 . The method of claim 1 wherein obtaining the vehicle parameter offset value comprises:
displaying an operator interface; and
receiving a parameter offset operator input through the operator interface, the parameter offset operator input being indicative of the vehicle parameter offset value.

7 . The method of claim 6 wherein displaying an operator interface comprises:
displaying the operator interface on the leading vehicle and wherein receiving a parameter offset operator input through the operator interface comprises receiving the parameter offset operator input through the operator interface on the leading vehicle.

8 . The method of claim 6 wherein displaying an operator interface comprises:
displaying the operator interface on the following vehicle and wherein receiving a parameter offset operator input through the operator interface comprises receiving the parameter offset operator input through the operator interface on the following vehicle; and
sending the vehicle parameter offset value to the leading vehicle based on the parameter offset operator input.

9 . The method of claim 1 wherein detecting a vehicle identifier comprises:
receiving an identifier signal from the following vehicle indicative of the vehicle identifier.

10 . The method of claim 1 wherein detecting a vehicle identifier comprises:
receiving the vehicle identifier from the receiving vehicle.

11 . The method of claim 1 wherein detecting a vehicle identifier comprises:
automatically detecting the vehicle identifier based on optical characteristics of the receiving vehicle.

12 . The method of claim 1 and further comprising:
detecting a mismatch between the vehicle identifier used to retrieve the vehicle parameter offset value and a currently-detected vehicle identifier; and
in response to the detected mismatch, retrieving the vehicle parameter offset value, based on the currently-detected vehicle identifier.

13 . The method of claim 1 wherein obtaining the vehicle parameter offset value comprises:
obtaining a plurality of vehicle parameter offset values each being indicative of a location of a different receiving vehicle parameter relative to the following vehicle reference point.

14 . A control system configured to control an unloading operation for unloading material from a leading vehicle into a receiving vehicle that is propelled by a following vehicle, the following vehicle and receiving vehicle comprising a following vehicle/receiving vehicle pair, the control system comprising:
at least one processor; and memory storing instructions executable by the at least one processor, wherein the instructions, when executed, cause the control system to:
retrieve a vehicle parameter offset value using a vehicle identifier corresponding to the following vehicle/receiving vehicle pair, the vehicle parameter offset value being indicative of a location of a receiving vehicle parameter relative to a reference point on the following vehicle;
detect a mismatch between the vehicle identifier used to retrieve the vehicle parameter offset value and a currently-detected vehicle identifier; and
in response to the detected mismatch, perform vehicle parameter offset value retrieval based on the currently-detected vehicle identifier.

15 . The control system of claim 14 , wherein the instructions, when executed, cause the control system to:
retrieve the vehicle parameter offset value, based on the vehicle identifier, and identify a position of the receiving vehicle based on the vehicle parameter offset value; and generate an unloading control signal to control the unloading operation based on the retrieved vehicle parameter offset value.

16 . The control system of claim 14 , wherein the instructions, when executed, cause the control system to:
automatically detect the vehicle parameter offset value corresponding to the vehicle identifier.

17 . The control system of claim 14 , wherein the instructions, when executed, cause the control system to:
generate an operator interface and receive a parameter offset operator input through the operator interface, the parameter offset operator input being indicative of the vehicle parameter offset value.

18 . A method of controlling an unloading operation for unloading material from a leading vehicle into a receiving vehicle that is propelled by a following vehicle, the method comprising:
detecting by a receiving vehicle sensor on the leading vehicle, a receiving vehicle parameter; determining a first relative location of the receiving vehicle parameter, detected by the receiving vehicle sensor, relative to a leading vehicle reference point on the leading vehicle; determining a second relative location of the receiving vehicle parameter relative to the following vehicle reference point based on the first relative location of the receiving vehicle parameter relative to the leading vehicle reference point on the leading vehicle; generating a calibrated offset value, based on the second relative location and controlling the unloading operation based on the calibrated offse
