Automotive Functional Safety- ISO 26262
A Streamlined Approach to Meeting Today's Functional Safety Requirements
Just as in Aerospace, the International Standards Organization has created the functional safety standard, ISO 26262, for the automotive industry. Functional safety is the part of the overall safety of a system or piece of equipment that depends on the system or equipment operating correctly in response to it inputs, including the safe management of likely operator errors, hardware failures, and environmental changes.
Why is ISO 26262 Important?
In terms of the automotive industry- OEM’s and suppliers to those OEM’s need to follow the specific ISO 26262 functional safety standard that is intended for safety regulations on the electronic systems of an autonomous vehicle. Without the specific safety standards in place, there would be no regulation controlling the development of self-driving vehicles. In the eyes of the consumer, the ISO 26262 standard should be the fail-safe that measures the competency of an autonomous or semi-autonomous vehicle they are entrusting their lives in. The ISO 26262 standard measures the safety system, performance, or probability of failure within the electronic components in a vehicle with autonomous features.
Per industry experts, the automotive industry is projecting fully autonomous (Level 5) cars by 2021. While the idea of full autonomy seems to be ever more present, a survey from AAA found 75% of U.S. drivers are afraid of relinquishing total control of a 2-ton vehicle to coding. For the average consumer, safety is a top contributing factor when deciding to purchase a new vehicle. With the autonomous trend becoming more of a reality by the minute, OEM’s, suppliers, and government bodies are going to have to band together to ensure consumer safety is on top of mind.

ISO 26262 Facts and Tips
While ISO 26262 seems to be a well-known industry topic, there are still questions surrounding the process and how it is used.
LHP’s functional safety experts weigh in on tips and facts surrounding the ISO 26262 standard
1. ISO 26262 has 8 parts beginning with overall safety management, systems management hardware management, software management, Production & operations, and then supporting processes.
2. ISO 26262 now expands to include ALL road vehicles including; RVs, tractor trailers, busses, and utility vehicles.
3. ISO 26262 governance can be effective in any organization- start-ups, suppliers, and OEMs.
4. ISO 26262 processes must be planned and integrated with quality management processes.
5. The ISO 26262 safety lifecycle encompasses activities during the concept phase, product development, production, operation, service and decommissioning.
6. You can self-certify for ISO 26262, as well as be certified by governing bodies.
7. The ISO committee is attempting to address autonomous driving in the next revision of ISO 26262
8. LHP designed its first safety critical system over a decade before ISO 26262 was released
9. Being ISO 26262 ready will give you the competitive edge over suppliers who are not ready
10. Did you know- one or more functional safety audits are to be performed by your customer? A functional safety audit evaluates the implementation of the processes required for the functional safety activities.
