BACKGROUND
A top automotive parts supplier specializing in steering systems and mechatronics, partnered with us to accelerate Electric Power Steering (EPS) model development and strengthen ISO 26262 compliance using a Model-Based Design (MBD) approach. We improved test automation, increased software reliability, and reduced hardware-dependent validation, helping them achieve safety-critical standards in software-defined vehicles (SDVs).
THE CHALLENGES
Addressing the
critical gaps
Build reusable EPS model libraries for EPS functions that could support multiple vehicle platforms while preserving functional consistency.
Ensure system meets ISO 26262 and AUTOSAR standards without slowing down development caused by safety validation activities.
Strengthen code reliability through MISRA-C compliance checks, static code analysis, and early runtime error detection before system integration.
Reduce hardware dependency and accelerate validation cycles through efficient simulation-driven testing (MIL, SIL, integration testing).

THE ROBOSOFT SOLUTION
We built and optimized EPS Simulink/Stateflow models using a MBD approach. Every model went through structured reviews with MXAM (Model Examiner) to make sure it followed MAAB, JMAAB, and ISO 26262 guidelines for easy readability, maintainability, and scalability.
Applied Polyspace Code Prover and Bug Finder with MISRA-C for static code analysis. We designed and implemented unit testing (MIL/SIL) using BTC Embedded, automating test case execution and reporting. With integration testing for SIL environments, we validated real-world EPS conditions and interactions with MCU, Powertrain, and vehicle networks.
With structured and outcome-driven documentation, we provided transparent traceability of contributions from requirements through model, code, and test results.
