About Garrett EWS

Garrettย EWSย (Early Warning System)ย is built to drive a reduction in the cost ofย unplannedย downtimeย & breakdownย on fleets,ย reduce the number of expensive repairsย caused by issue escalation and improve the safety of drivers and passengers.ย ย 

Through early fault detection, Garrett EWS enables fleet managers to shift from regular maintenance appointments towards maintenance to address specific vehicle needs, keeping the vehicleย active on the roadย with the knowledge that vehicle is operating in full health.ย 

Extensiveย testingย has shown significant results including detection of faults up to 21 days before vehicles were signaling a DTC (Diagnostic Trouble Code) and providing fleet managers with insight up to 90 days ahead of a possible vehicle failureย preventingย avoidable downtime and reducingย the risk of the issue escalating to multiple systems over this time.ย 

Withย a dongle placed on the vehicle in partnership with our Telematics Service Providers, Garrett accessesย signal and CAN data.ย ย 

Garrettโ€™s sophisticated diagnostic tools interpret and analyze all theย incomingย signals.ย Through complex algorithms Garrett EWSย interprets and analyses system and sub-system behaviorย in near real timeย whilst theย vehicleย is running. Garrett EWS will signal any anomalies and predictions directly to the fleet manager with clear visibility on theย vehicle health and failure risks.ย ย 

Garrett EWS is designed for the fleet manager with alerts on vehicles at risk and easy visual representation of vehicle behavior across the entire fleet. Garrettย EWS is available on OBD2, J1939 supporting both passenger and commercial vehiclesย 

 

The Pillars of EWS

Detection: Garrett EWS analyses data from the vehicle telematics and identifies a problem in the vehicle behavior near-time. An anomaly can be detected due to a change in the behavior of a mechanical part or a change in fluid e.g. fuel type. ย 

Diagnostics: Garrett EWS pinpoints the issue location, notifies the fleet manager and stores the data history for easy visualization in the garage. Real time fault diagnostics reduces the need to replicate the fault increasing first time fix and reduce time off the road.ย 

Prognostics:ย Driver and vehicle behavior is analyzed using Physics based models (PBM), Artificial Intelligence (AI) and Machine Learning enabling fault prediction from 2 up to 90 days before a critical fault. Reduce unplanned downtime through scheduled maintenance.ย ย 

Service Management: Garrettย EWS compiles a full fault and DTC history including the ability to produce reports of vehicle behavior at the time of the fault. Instantly compare pre and post-fix data.ย 

Garrett EWS also provides follow-up on the repair and produces the evidence in case of a wrong or failed repair.ย 

 

Prediction Types

Remaining Useful Life: Garrett EWSย predicts how many miles & how much time is left from a specific component until it needs to be replaced.ย 

Fault predictions: Garrett EWSย determines if a specific component is prone to failures in an immediate time frame (2-90 days).ย 

Health scoring: Garrett EWSย predicts if a certain component will have an important health degradation in a foreseeable time frame andย whetherย it can affect other systems.ย 

With different vehicle systems and subsystems producing different types of faults, Garrett EWS runs specificย prediction algorithms depending on the system type.ย 

 

Technologyย 

The Garrett EWS platform isย fully developed on cloud technology enabling easy on-boarding of all fleet types and sizes with the platform expandingย to fleetย and analytic needs.ย 

The Garrett EWS platform runs Machine learningย (ML), Artificial Intelligenceย (AI)ย andย Physicsย basedย Modelingย (PBM) that allow the platform to continuously ingest and learnย the characteristicsย and contextย ofย each vehicle in yourย fleet.ย 

GARRETT EWS USE CASES

  • Break Lining Saving
  • Engine Overheat Avoidance
  • Aftertreatment Issues

Garrett EWS diagnostics on break pad lining enables an accurate assessment on break lining lifespan. On average Garrett EWS enables an 8.2% extension on the lifespan of the break pad by running diagnosis on sensor data, driver behavior and vehicle usage. By doing so Garrett EWS enables break pads to be replaced based on real break pad wear on Commercial and Light Commercial vehicles.ย ย 

Garrettโ€™sย assessment deliveredย an averageย saving 560 Euro/year/bus offering over $33K saving per year on aย 60 busย fleet.

By combining sensor data, driver data and vehicle context,ย  Garrett EWS canย prevent the risk ofย anย engine overheat on commercial vehicles, Light commercial vehicles and Passenger vehicles.ย The Garrett EWS platform has delivered 100% accurate detection rate and prevented otherwise undetected engine failures saving over 650 Euro of costsย on a single failure.ย 

Garrett EWS provides early detection on aftertreatment issues on Commercial, light commercial as well as Passenger vehicles.ย  Garrett EWS analyses sensor data combined with vehicle and driver context to make a vehicle system assessment. With a detection accuracy at 86% Garrett EWS has enabledย early vehicle interventionย which resulted in the elimination of an aftertreatment over haul,ย preventing over $2K inย unplannedย costs.ย 

The Garrett EWS Platform

The Garrett EWS interface is designed for the fleet manager to haveย easy visibility of their entire fleet withย full control enabling the ability to drill down toย specific vehicle issues at the click of a button. The fleet canย be managed with a prioritization of common issues, or withย visibility by fleet type and usage.ย

Early Warning System Frequently Asked Questions

Q: If I buy the Garrett EWS Solution from Garrett, will I also need hardware?
Q: Who is the ideal user for Garrett EWS, the Garage or fleet manager?
Q: Does Garrett build the hardware dongles?
Q: Will my Choice of hardware impact the quality of the Garrett EWS solution?
Q: Will the Garrett EWS system allow for remote changes?

A:

This depends on the telematics capability – if they allow to write we can overwrite to change anomalies on the Garrett EWS Platform

Q: Is Garrett EWS Compatible with all vehicles?

A:

Yes. Garrett EWS can connect to OBD2 as well as singles from trucks and trailer units (J1708 & J 1939)

Q: How does Garrett Manage personal data?

A:

Personal data is only used to give the fleet manager visibility on their fleet and is not shared. When the service ends or upon request all personal vehicle data will be erased. Garrett gathers anonymous data from the vehicle to enable predicative modeling. This data is not personalize and can not lead to the identification of a specific vehicle or individual.

Q: How is EWS different to DTC (Diagnostic Trouble Code) decoding?

A:

DTCs arise when the vehicle ECU has identified an error. DTC decoding will notify the user of an impending error. Through EWS the fleet manager will be notified of potential risks before the DTC is being detected, enabling for more time to schedule the vehicle for maintenance at the most optimal time.
