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
