Buffering time optimization for path tracking accuracy in remote vehicle control with digital twin computing

On path tracking control of vehicles via the Internet, transmission delay and jitter prevent them from a target accurately. To improve accuracy, it is effective to apply digital twin computing buffer system. The system with has an issue optimizing buffering time. Through simulations by using some realistic models, we quantitatively evaluated accuracy depending on As result, showed that buffered packet rate (BPR) can be key index optimize time according delay.
