Solid-state indication system for automotive application / Nasrul Rahman Abdullah

This project involved the design of solid-state indication system for automotive application. The significance of the project is in the designing of active brake signal and the application of low power solid-state device as replacement to the conventional indication system for automotive. The system is designed to increase safety and reduce the power consumption in vehicle. During initial design session, the existing system was studied. The area of improvement is identified and a rough system design is proposed. Also, the related international standard was collected to ensure proposed design follows the international requirements. Once the proposed design has satisfied the objective of the project, the circuit was designed with suitable values. After all the circuit has been satisfied, a computer simulation using OrCAD® Capture v9. l series - an electronics aided design software was performed. When all the simulation results satisfied with the design specification, the circuit was constructed and tested on a test board. Here component values were adjusted and the circuit was fine tuned. In conclusion, the system constructed met the specification by the design, simulation and build. There were few improvements should be done to the system for better functionality, as mentioned briefly in future development.
