Abstract

The progressive electrification of the transportation sector has necessitated the development of advanced, efficient, and centralized electronic control systems in Electric Vehicles (EVs). This paper addresses the growing demand for intelligent powertrain management. This paper demonstrates a practical implementation of a centralized control architecture capable of managing traction, illumination, and signalling functions simultaneously, thereby reflecting real-world automotive engineering practices.

The core problem addressed is the fragmentation and inefficiency of decentralized vehicle electronics. Traditional architectures require separate control modules for each subsystem, resulting in heavy wiring harnesses, multiple failure points, and poor adaptability. The objective is to consolidate traction control, dashboard illumination management, and indicator blinking into a single microcontroller-based VCU using multi-channel PWM.
