IVHM – Proven in Aerospace, new ideas for Automotive


Integrated Vehicle Health Management - Definition

...the transformation of system data into information to support operational decisions that results in: • Enhanced operational awareness • Minimised maintenance action/time • Improved readiness and availability • Reduced inspections and troubleshooting • Reduced redundancies & design margins • Reduced schedule interruptions • More efficient logistics operations • Reduced environmental impact hence creating real business benefit

SAE History - and Future….

SAE (automobile) formed in 1905 to promote safety and common practices for the emerging automobile market.

Automobile & Aeronautic Engineers Societies merged in 1917 to create SAE. 1st SAE Aerospace Standard, 1917

SAE E-32 – EHM committee established, 1975

G-11 SHM is formed – work begins on the SHM guidebook (ARP6461), 2008

IVHM Steering Group established in June, HM-1 Committee in October, 2010

SAE AeroTech, first SAE IVHM Book, 2011

IVHM Business Case Book published, 2012

SAE AeroTech, IVHM and SHM Panel Session @ LHT, 2013

10 HM-1 documents in progress, 7 HUMS/IVHM standards published

TYPES OF SAE AEROSPACE STANDARDS

11

AS Aerospace Standards – specific performance requirements used for design standards, parts standards, minimum performance standards, quality and other areas conforming to broadly accepted engineering practices or specs for a material, product, process, procedure or test method AMS Aerospace Material Specifications – specific performance requirements for material and process specifications ARP Aerospace Recommended Practices – documentations of practice, procedures, and technology that are intended as guides to standard engineering practices. May be of a more general nature or propound data that have not yet gained broad acceptance. AIR Aerospace Information Reports – compilations of engineering reference data, historical information, or educational material useful to the technical community

IVHM, Maintenance Credits and Safety

A new SAE document addressing IVHM, Maintenance Credits and Safety is in development. This will look at the role IVHM may be able to play in the safety case – and will leverage synergies with the Safety Management community and safety data.

No Fault Found

While the technology development is progressing, supported by standards, the next frontier is implementation.

Reduction or elimination of No Fault Found is a key component, and will help to prove the reliability of the system necessary to take “credit” for the use of IVHM – a major driver for airlines. A new SAE book exploring NFF was published in September 2015.

SAE IVHM Initiative – Future Focus



• The shift from the sale of products to the sale of services requires IVHM. • Much progress has been made in this field over the last 10 years, in many

different sectors. • SAE is putting aerospace standards in place for IVHM at the vehicle level,

along with education and training. • The goals that are being set for the future could affect how IVHM relates to

maintenance and safety.
