It is really nice to note that your field of discipline is electronics and you are looking for a project related to Automotive Electronics. I have done B.E. Electronics from NUST. My final year degree project was, "Design & Fabrication of ECU for both Petrol & CNG fuels". The ECU was encompassing both Electronic Fuel Injection (EFI) and Distributorless Ignition System (DIS). In addition, we had kept On-board Diagnosis (OBD) in it. The project was lively demonstrated on a car.
I want to guide you a bit that this project really demands your full dedicated efforts but at the end you can know which is really differentiating. Our project was sponsored by Dewan Farooq Motors and we had their total support in the availability of car, any additional sensors/actuators/wires/components we needed. More to this we had some set of instruments all time available with us from our institute.
What you have decided as your final year project?
BTW, do you know that we had met in ISB when we displayed Tire Pressure Monitoring System (TPMS)!
