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
