Embedded software is central to modern automotive systems, demanding rigorous practices for safety and reliability. This study compares three code development approaches—unconstrained manual coding, standards-compliant manual coding (MISRA C, ISO 26262), and automatic Simulink-based generation—applied to Vehicle Speed Sensor and Engine Temperature Display subsystems. Quantitative evaluation demonstrates that standards-compliant manual coding balances safety assurance with implementation efficiency, while model-based generation excels in traceability and development speed. The analysis extends to industrial implications including certification, cost, and scalability, while proposing hybrid workflows that leverage both methodologies’ strengths.

摘要

Embedded software is central to modern automotive systems, demanding rigorous practices for safety and reliability. This study compares three code development approaches—unconstrained manual coding, standards-compliant manual coding (MISRA C, ISO 26262), and automatic Simulink-based generation—applied to Vehicle Speed Sensor and Engine Temperature Display subsystems. Quantitative evaluation demonstrates that standards-compliant manual coding balances safety assurance with implementation efficiency, while model-based generation excels in traceability and development speed. The analysis extends to industrial implications including certification, cost, and scalability, while proposing hybrid workflows that leverage both methodologies’ strengths.
