Introduction to IVHM – Integrated Vehicle Health Management

Here’s a short (about ten minutes) presentation I made recently on Integrated Vehicle Health Management (IVHM).

What is Integrated Vehicle Health Management?

Integrated Vehicle Health Management strives to assess the current and future health of a vehicle. That health information is passed onto people who can use it to help plan operations and maintenance for that vehicle (or a fleet of vehicles).

You may also come across Integrated Systems Health Management (ISHM) and Prognostic Health Management (PHM) being used to describe the same sort of thing.

The IVHM name was coined by NASA in the early 1990s.

To oversimplify the idea, you stick sensors on a vehicle and use the data to assess its current state (and possibly future states) so that people can make better-informed decisions about that vehicle.

There are two parts to IVHM. First, the system – equipment and sensors needed to capture and process the information. And second, the service – using of the information to better manage the use and maintenance of the vehicle.

Some of the advantages that can be achieved from implementing IVHM are:

  • Improved safety – diagnostic and prognostics can be used to identify faults or even predict them before they happen.
  • Improved availability – through the better scheduling of maintenance.
  • Improved reliability – through a better understanding of vehicle and its health.
  • Reduced cost – through reduction of unnecessary maintenance and avoidance of unscheduled maintenance.

The SAE International has published several books on IVHM and they offer a great introduction into the topic.
