Fail-operational electric power steering (EPS)

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.

A global leader in automotive applications, Infineon offers a complete fail-operational EPS chipset from one source that’s unique on the market. All eight components are proven to work together smoothly and have been tested to ensure they fulfill all safety requirements. Unlike standalone solutions, our chipset is aligned, so you get the level of safety you need with much less development effort required on your part. Furthermore, the small footprint of our solution enables to reduce your BOM and it’s scalable to accommodate various can models and driving modes. Finally, you can be sure that all components in our chipset uphold Infineon’s zero defect quality standard for automotive components.
