💡 Simulink Requirements – MATLAB Implementation Ideas

⬅️ Back These requirements are ideal for Level 1 & 2 interviews and practical automotive model-based design projects. They can be implemented in MATLAB/Simulink and validated using Simulink Requirements, Traceability, and Test Manager.

🚦 1. Brake Light Control System

Requirement:
- If the brake pedal is pressed, the brake lights shall turn ON.
- If the brake pedal is not pressed, the brake lights shall turn OFF.

Inputs:
- Brake_Pedal_Status (Boolean)

Output:
- Brake_Light (Boolean)

Implementation Hints:
- Use If-Else or logical operator blocks.
- Model must respond instantly to pedal press.
- Link requirement via Simulink Requirements.

🌡️ 2. Temperature Warning System

Requirement:
- When engine temperature exceeds 95°C, turn ON the warning indicator.
- When engine temperature falls below 90°C, turn OFF the warning indicator.

Inputs:
- Engine_Temp (double, °C)

Output:
- Temp_Warning_Lamp (Boolean)

Implementation Hints:
- Use Hysteresis logic to avoid flickering.
- Apply memory block for state retention.

🛑 3. Emergency Stop Logic

Requirement:
- If both Brake_Pedal is pressed AND Obstacle_Detected is true, trigger Emergency_Stop.

Inputs:
- Brake_Pedal_Status (Boolean)
- Obstacle_Detected (Boolean)

Output:
- Emergency_Stop (Boolean)

Implementation Hints:
- Use AND logical block or condition action subsystem.
- Test multiple scenarios using signal builder or test harness.

⛽ 4. Low Fuel Indicator System

Requirement:
- Turn ON Low_Fuel_Lamp when Fuel_Level falls below 10%.
- Turn OFF when Fuel_Level rises above 15%.

Inputs:
- Fuel_Level (percentage, double)

Output:
- Low_Fuel_Lamp (Boolean)

Implementation Hints:
- Use Compare To Constant and Logic blocks.
- Add simulation data inspector traceability.

🔄 5. Gear Shift Requirement

Requirement:
- If Vehicle_Speed > 40 and Engine_RPM > 2500, Shift Up.
- If Vehicle_Speed < 20 and Engine_RPM < 1500, Shift Down.

Inputs:
- Vehicle_Speed (km/h)
- Engine_RPM (rpm)

Outputs:
- Shift_Command (Enum: UP, DOWN, HOLD)

Implementation Hints:
- Use MATLAB Function block or Multiport Switch.
- Integrate with Stateflow for gear logic.

  • 📎 Link each requirement to the model block via Simulink Requirements.
  • 📊 Use Simulink Test to create test cases for each scenario.
  • ✅ Validate using coverage metrics, MIL or SIL.
  • 🔗 Maintain bidirectional traceability with requirement documents.

📝 You can extend these with AUTOSAR properties, integrate into SWCs, or simulate with CAN messages as per domain-specific projects (Maruti, Bosch, Nissan, etc.)
