What are the current main challenges for functional safety regulations and applications in the non-road sector? What are the requirements for reliable system safety analysis? How do you deal with rising complexity in control systems? To help you to keep up-to-date with the latest developments in this area, Automotive IQ spoke exclusively to Pierre Loisy, Safety Manager at Volvo Construction Equipment in Sweden.

1. Speaker at the 4th International Conference FunctionalSafety for Non-Road
Vehicles and Mobile Machinery:
Pierre Loisy,
Safety Manager at
Volvo Construction
Equipment

2. Pierre Loisy acts as Functional Safety Manager at the sub-division of compact excavators, Volvo
Construction Equipment (VCE). He handles the process leading to the verification of functional
safetyrequirements for both the hardware and software embeddedcontrol platforms in the frame
of the CE mark. Mr. Loisy shares his time between supporting product development teams,
personal and in-house collaborative investigation of advanced assessment and verification
techniques through exploring various functional safety standards.
Mr. Loisy, where do you see the current main challenges for functional safety regulations and
applications in the non-road sector?
I would say that the construction equipment industry is actually seeking in between different standard
based approaches providing a workflow stability, proven tools and practices, all kind of that suitable
baseline for addressing functionalsafety processconcerns as well as reaching the best confidence level;
 IEC61508 universal standard, however not narrowed to the construction equipment domain
 ISO26262 automotive standard, but not machinery directive integrated, aimed for SEooC
 ISO13849/ISO62061packed standards, aggregation not yet done to turn it a fit for purpose
 ISO25119 agriculture products related standard, no machinery directive integration
One can easily see that none of those can reasonably be aimed to cover our structural and safety cases
needs as a standalone route, thus an overlapping strategy is likely to be appropriate
What are the requirements for reliable system safety analysis? How do you deal with rising
complexity in control systems?
I guess it’s all about the risk mitigation techniques and processes implemented in the design aimed to
achieve an acceptable –tolerable- risk level while operating a machine. Risks and hazards are naturally
unavoidable elements of our lives. Appropriatelymanaging the risk is what makes a technology suitable
and mature enough for the market place.
