Project 2 - Development of Coolant Temperature Software Component Meter

Project 2 - Development of Coolant Temperature Software Component Meter

The Engine Coolant Temperature Sensor is a temperature variable resistor, which usually has a negative temperature coefficient. It is a two wired thermistor immersed in coolant and measures its temperature. The temperature value is then given to the ECU. From there, the vehicle ECU will use this temperature information to either continue operating or adjust certain engine functions, always working to keep the engine temperature at an optimal level. Coolant Temperature Meter receives Engine Coolant Temperature Signal from the CAN whenever Ignition is turned ON. Subsequently, Signal Processing is performed for Coolant Temperature Indication.

Key Highlights:

• Project covers contents from Week 3 to Week 10
• Objective of the project is to calculate the speed value which is getting displayed in the cluster unit
• Stages of development starts from Requirement Engineering to Model Development complying to JMAAB guidelines
• This is followed by Simulink Design Verifier – Design Verification stage.
• This is followed by writing functional test cases, MIL & SIL validation.
• Next is Simulink Design Verifier – Test Generation Criteria
• Next stage is Polyspace Static Code Analysis followed by test automation using Simulink Test Manager

Deliverables:

• Software Requirement Report (SwREQ document)
• Working Model with SLDD file
• Reports including JMAAB, Requirement Tagging report, SLDV reports & MIL – SIL Coverage Reports
• Auto - generated code
• MIL SIL Test Harness, Test Results & Functional Test Cases
• QA Static Code Analysis results
• Simulink Test Manager Results
