Fail-operational electric power steering (EPS)
A safety-first step in future-ready cars
Fail-operational electric power steering (EPS) is a safety critical application in cars that are increasingly autonomous. A redundant system ensures that EPS will continue to function even in the highly unlikely event of a system failure. Beyond fulfilling safety requirements and providing peace of mind, a fail-operational design also provides all the advantages of a standard EPS system. For instance, drivers benefit from around 3% less fuel consumption and an improved overall driving experience while engineers and manufacturers look forward to space savings and easier integration.
