Steering Hand Sensing System – Functional Safety ASIL-B

Home Case Studies Steering Hand Sensing System – Functional Safety ASIL-B

Project Scope


  • Review Existing Non-Functional Safe Legacy Steering Hand Sensing System Software and Re-architect it to meet ASIL-B Functional Safety (ISO 26262) rated Software

  • Understand Safety Goals and create Functional Safe Software Requirement Specifications, Software Architect Design, Software Detailed Design, Code


Business Challenges

Redesigning the Non-FuSa System to meet FuSa is time consuming.


ARi’s Solutions


  • Created SRS, SAD, SDD and code based on Technical Safety Requirements, System Design Specification and rated each for FuSa (ASIL-B/QM)

  • Partitioned the existing SWCs for ASIL-B and QM, and allocated respective resources


ARi’s Value Proposition


  • Implemented Memory Protection Unit (MPU) and Fault Injection Testing (FIT) to achieve Safety Standards

  • Implemented software for the components like CRC Driver ASIL-B, CAN Driver, CAN Network Manager, CAN Interface Manager, Fault Manager ASIL-B, Fault Manager QM modules.

  • Achieved Functional Safety ASIL-B compliance for Steering Hand Sensing System
