This project offers an engaging way to explore the world of expert systems and rule-based programming using CLIPS, specifically within the context of automotive diagnostics. Designed as a practical learning tool, this expert system simulates the process of diagnosing common car problems based on user input. Initially focused on engine starting, running, and performance issues, the system has been significantly enhanced to include a broader range of maintenance checks, providing a more comprehensive diagnostic experience.
It is crucial to remember that this project is intended solely for educational purposes. It should not be used as a substitute for professional automotive diagnosis or repair advice. Always consult with a certified mechanic for any concerns regarding your vehicle.
Enhanced Car Maintenance Diagnosis
Extended Maintenance Checks
Beyond the engine’s basic functions, the updated car diagnosis expert system now delves into crucial maintenance aspects. When the system determines that the engine starts and runs normally, it proceeds to inquire about the following key maintenance checks:
0. Oil level
1. Coolant level
2. Transmission fluid level
3. Brake fluid level
4. Tire pressure
5. Tire tread depth
6. Air filter condition
7. Windshield wiper fluid level
8. Serpentine belt condition
9. Dashboard warning lightsThese additions broaden the diagnostic scope, allowing users to understand the interconnectedness of various vehicle systems and the importance of regular maintenance.
Smart Repair Suggestions
Responding to the answers from these new maintenance checks, the expert system now provides intelligent repair suggestions. This feature guides users on addressing common maintenance-related issues. For instance, it offers advice on rectifying low fluid levels, correcting abnormal tire pressure, recognizing worn tires, replacing clogged air filters, and interpreting dashboard warning lights. This practical guidance empowers users to learn about basic car maintenance and potential solutions.
Refined Engine Running Logic
The system’s logic has been further refined with an update to the “runs normally” rule. Previously limited to “yes” or “no” responses, the system now accommodates a “maybe” answer. This enhancement allows for more nuanced user input, acknowledging cases where engine performance might be uncertain or intermittent. The underlying rules of the expert system have been adjusted to effectively process this “maybe” response, leading to more accurate diagnostic outcomes.
Using the AI Expert System for Car Diagnostics
To begin using this enhanced automotive expert system AI project, you will need the CLIPS IDE (Integrated Development Environment). You can download the necessary software from the official source: CLIPS 6.40
Once you have installed the CLIPS IDE, follow these simple steps to run the car diagnosis expert system:
1. Launch the CLIPS IDE on your computer.
2. Open and load the provided CLIPS code file into the IDE.
3. Before each use, ensure you "Reset" the system within the CLIPS environment. Then, initiate the expert system's execution.
4. The system will then guide you through a series of questions. These questions are designed to gather information needed to diagnose potential issues with the vehicle, based on your specific answers.
5. Carefully respond to each prompt with accurate information about your car's condition. Based on your responses, the system will provide a suggested repair action aimed at resolving the identified problem.By working through this project, users can gain valuable hands-on experience with AI-driven car diagnosis concepts and improve their understanding of expert systems in a practical, automotive context.
