Modern vehicles are rapidly evolving into intelligent systems that integrate electronics, communication, and embedded control to enhance safety, efficiency, and user experience. Traditional vehicle control systems rely heavily on isolated modules with limited monitoring and manual diagnostics, which reduces reliability and scalability. This paper presents the design and implementation of an Intelligent Vehicle Control and Monitoring Unit (IVCMU), a layered embedded system that integrates real-time control, monitoring, security logging, and wireless communication. The proposed system uses a microcontroller-based architecture to monitor critical vehicle parameters such as speed, temperature, and system status, while also enabling remote data access and control through wireless interfaces. The modular layered architecture improves fault isolation, expandability, and system reliability. The IVCMU demonstrates how embedded systems combined with communication technologies can provide a cost-effective and scalable solution for next- generation intelligent vehicles.
