Protecting vehicle wire harnesses from overloads that could be catastrophic is a critical design criterion. The designer must ensure that the fusing strategy protects the wiring. This process typically involves calculating the maximum load on each wire manually and then comparing the result to a spreadsheet that may have been created many years ago. This process is very error prone due to its manual nature. You might find that alarming — and it is — but cars and planes are driving and flying just fine. There are several reasons that is so…

    Very interesting plunge into a set of questions there is no industry-wide standard answer for in automotive (yet).

    – How much analysis is enough in the sense for example of “safe enough” – when there are thousands of purchasable variations in the car?
    – What human expertise using what software tools can adequately model the behaviors you are interested in over the car platform?

    Mike’s showing the way to achieve the coverage engineers developing the cars need, and that will provide the reassurance owners of cars and regulators demand without adding cost.
