Vehicle Infotainment System (2025)
Project Overview
VehicleSys is a sophisticated automotive infotainment interface developed as a personal learning project to demonstrate advanced Qt/QML development skills and modern C++ programming practices. The project showcases professional-grade automotive UI development with real-time vehicle control systems, climate management, and interactive multimedia interfaces.
Technical Architecture
The application demonstrates advanced Qt/QML integration patterns with a clean separation between C++ backend controllers and QML frontend components. The architecture follows professional automotive software development standards with modular component design and real-time property binding systems.
Backend Controllers (C++)
- System Controller: Manages core vehicle state including lock status, temperature monitoring, and user authentication
- HVAC Handler: Dual-zone climate control system with independent driver/passenger temperature management (50-90°F range)
- Audio Controller: Dynamic volume management with four-state visual feedback system
Frontend Components (QML)
- Modular Architecture: Reusable component system with configurable parameters
- Property Binding: Real-time UI updates using Qt's reactive property system
- Event Handling: Responsive mouse interactions with immediate visual feedback
