Advanced Real-Time Performance QEMU Emulated Automotive Control System with a Multithreaded PID Controller

초록

Modern vehicles are frequently exposed to a wide range of driving conditions, where external disturbances-such as inclines, heavy loads, or varying road surfaces-can significantly affect control performance. Despite the integration of advanced autonomous driving algorithms, manual intervention by the driver is still often required. In this study, we propose a multithreaded PID controller capable of rapidly compensating for the discrepancy between desired and actual system outputs. Implemented in standard C and deployed within a QEMU-based virtual environment, the controller ensures portability across various hardware platforms and is validated through a Simulink-integrated simulation model. The proposed architecture enables consistent and precise vehicle control without driver intervention, demonstrating real-time responsiveness and platform-independence. © 2025 IEEE.
