Abstract

A filter monitoring system and method are described. The filter monitoring system includes a remote telematics system, and a data link between the remote telematics system and an onboard telematics system. The remote telematics system is configured to receive, via the data link, an indication of a pressure drop across a filter cartridge of the filtration system from the onboard telematics system, determine a first value indicative of a remaining filter life of the filter cartridge of the filtration system, determine a second value indicative of a remaining filter life of the filter cartridge that is determined in a different manner than the first value, compare the first value to the second value to determine which value indicates a least amount of life remaining for the filter cartridge, and transmit an indication of the least amount of life remaining for the filter cartridge based on the comparison.

First claim

What is claimed is:

1. A monitoring system for a filtration system, comprising:
a remote telematics system; and
a data link between the remote telematics system and an onboard telematics system, wherein the remote telematics system is configured to:
receive, via the data link, an indication of a pressure drop across a filter cartridge of the filtration system from the onboard telematics system;
determine a first value indicative of a remaining filter life of the filter cartridge of the filtration system based at least in part on the indication of the pressure drop across the filtration system,
determine a second value indicative of the remaining filter life of the filter cartridge based at least in part on the amount of time the filter cartridge has been used in the filtration system, the second value determined in a different manner than the first value,
compare the first value to the second value to determine which of the first value or the second value indicates a least amount of life remaining for the filter cartridge, and
transmit an indication of the least amount of life remaining for the filter cartridge based on the comparison.

2. The monitoring system of claim 1 , wherein the remote telematics system is configured to:
receive, via the data link, an engine parameter of a vehicle; and
determine a current flow rate of fluid through the filtration system based on the engine parameter, and wherein determining the first value comprises:
comparing the indication of the pressure drop with a terminal pressure drop of the filter cartridge at the current flow rate; and
updating the first value based on the comparison.

3. The monitoring system of claim 1 , wherein the data link is a wireless data link.

4. The monitoring system of claim 1 , wherein the remote telematics system is part of a remote telematics system, and wherein the onboard telematics system communicates with an engine control module of a vehicle.

5. The monitoring system of claim 1 , wherein the remote telematics system is further configured to:
receive, via the data link, an identifier associated with a radio frequency identity tag of the filter cartridge;
determine an installation date of the filter cartridge based on receiving the identifier; and
determine the amount of time the filter cartridge has been used in the filtration system based at least in part on the installation date.

6. The monitoring system of claim 1 , wherein transmitting the indication of the least amount of life remaining comprises sending, by the remote telematics system, the indication of the least amount of life remaining to at least one of a display console, an operator or technician computing device, the onboard telematics system, or an external telematics service.

7. The monitoring system of claim 1 , wherein the indication of the least amount of life remaining is transmitted to the onboard telematics system, wherein transmitting the indication of the least amount of life remaining causes an engine control circuit of a vehicle to derate an internal combustion engine of the vehicle or prevent the internal combustion engine from starting.

8. An apparatus, comprising:
a filter monitoring system circuit comprising a memory storing machine readable instructions and a processor, the machine readable instructions structured to cause the processor to perform operations comprising:
determining a first value indicative of a remaining filter life of a filter cartridge of a filtration system monitored by the filter monitoring system circuit, the first value based at least in part on an indication of a pressure drop across the filtration system;
determining a second value indicative of the remaining filter life of the filter cartridge based at least in part on an amount of time the filter cartridge has been used in the filtration system, the second value determined in a different manner than the first value;
comparing the first value to the second value to determine which of the first value or the second value indicates a least amount of life remaining for the filter cartridge; and
transmitting an indication of the least amount of life remaining for the filter cartridge based on the comparison.

9. The apparatus of claim 8 , wherein the machine readable instructions are structured to cause the processor to further perform operations comprising:
receiving an engine parameter of a vehicle; and
determining a current flow rate of fluid through the filtration system based on the engine parameter, and wherein determining the first value comprises:
comparing the indication of the pressure drop with a terminal pressure drop of the filter cartridge at the current flow rate; and
updating the first value based on the comparison.

10. The apparatus of claim 8 , wherein the machine readable instructions are structured to cause the processor to further perform operations comprising receiving, via a wireless data link from an onboard telematics system, the indication of the pressure drop across the filter cartridge.

11. The apparatus of claim 8 , wherein the machine readable instructions are structured to cause the processor to further perform operations comprising:
receiving an identifier associated with a radio frequency identity tag of the filter cartridge from an electronic recognition circuit of the filtration system;
determining an installation date of the filter cartridge based on receiving the identifier; and
determining the amount of time the filter cartridge has been used in the filtration system based at least in part on the installation date.

12. The apparatus of claim 8 , wherein transmitting the indication of the least amount of life remaining comprises sending the indication of the least amount of life remaining to at least one of a display console, an operator or technician computing device, an onboard telematics system, or an external telematics service.

13. The apparatus of claim 8 , wherein the indication of the least amount of life remaining is transmitted to an onboard telematics system, and wherein transmitting the indication of the least amount of life remaining causes an engine control circuit of a vehicle to derate an internal combustion engine of the vehicle or prevent the internal combustion engine from starting.

14. The apparatus of claim 8 , wherein the machine readable instructions are structured to cause the processor to further perform operations comprising receiving an indication of a fluid quality from an onboard telematics system.

15. The apparatus of claim 8 , wherein the machine readable instructions are structured to cause the processor to further perform operations comprising receiving an indication of a presence of water in fuel from an onboard telematics system.

16. A monitoring system for a filtration system comprising:
a remote telematics system; and
a data link between the remote telematics system and an onboard telematics system, wherein the remote telematics system is configured to:
receive, via the data link, an indication of a pressure drop across a filter cartridge of the filtration system from the onboard telematics system;
determine a first percent loading of the filter cartridge based at least in part on the indication of the pressure drop,
determine a second percent loading of the filter cartridge based at least in part on the amount of time the filter cartridge has been used in the filtration system, the second percent loading determined in a different manner than the first percent loading;
compare the first percent loading to the second percent loading to determine which of the first percent
