EMC as Part of Vehicle

❱ ❱ Future vehicle technology demands a more risk based approach to EMC and cyber threat resilience

Jonathan Newell talks to HORIBA MIRA about its approach to automotive EMC testing as part of a holistic vehicle resilience concept.

requirements for the industry have moved on and so I spoke once again to Anthony Martin, the company’s Chief Engineer for EMC and head of vehicle resilience.


CHANGE OF EMPHASIS Whilst still fulfilling all of the EMC testing and verification services that are necessary for compliance with international standards, HORIBA MIRA is now moving towards covering the wider topic of vehicle resilience. I asked Martin what this means. He explained that resilience encompasses

the next generation of EMC, including the functional safety elements of EMC as well as new areas, such as cyber-security, which has an overall effect on consumer acceptance of the latest generation of cars with active safety and degrees of autonomy. “The concept is based on dependability,

durability and safety. All these need to come together for acceptance and resilience. For example, when something goes wrong, the vehicle systems need to recover safely, something that’s not catered for by simply complying to standards,” he explained. To illustrate this, Martin explained that failing

safe may involve the need to stop the car but that in itself isn’t necessarily a safe condition to fail to – does braking involve a sudden stop or coasting to the side of the road away from moving traffic? Resilience covers this.

RISK ASSESSMENT Currently, within the industry there’s no standard threat analysis package and this is something that HORIBA MIRA’s developing based on the multitude of developments that are happening across automotive technologies. “Vehicle Resilience is an approach of risk assessment and mitigation rather than compliance,” he says.

For example, currently EMC is standards based and although the vehicle manufacturers use enhanced versions of standards, they’re not necessarily related to resilience. The standards change based on adjustments in automotive technology so the EMC standard now has more focus on hybrid and electric vehicles so that manufacturers aren’t measuring performance based on standards written for vehicles that have entirely different power trains. HORIBA MIRA has significant influence in the development of the standards and implements changes in best practice into the EMC road map, according to Martin. The organisation is working on standards, which are applicable across the world as well as working with the industry to perform development activity that takes a risk management approach.


An area of resilience that HORIBA MIRA is taking a particular interest in is cyber-security, which Martin describes as being similar to EMC from a threat perspective in that, for example, there are both internal and external sources to consider. There are various types of attackers and attack methods, making cyber- resilience a complex area. “Defining cyber threats in fact uses a very similar engineering framework to what we’re used to. We use good engineering practices and deep knowledge of the technology to understand both the architecture and the software. This level of understanding of the system is essential to achieving secure designs,” he says. This is a very different approach to the

cyber threat protection that consumers are currently used to and I asked if it would ever be likely that there would be similarities in the automotive industry.

“One commercial piece of software won’t cover the complex architecture involved in vehicle technology. The resilience has to be designed into the product and our Future Vehicle Technology division is working on achieving this using other approaches, including Artificial Intelligence,” concludes Martin.
