Abstract：To address the issue of significant impact on vehicle terminal data transmission due to varying communication quality across regions and packet loss,this study further optimizes and enhances data transmission quality by designing an asynchronous architecture for data reading,storage,and transmission.Based on TCP protocol caching,a data buffer pool is introduced to separate data reception and transmission processes,enabling data buffering between blind zone storage and real-time transmission modes for vehicle terminals.By comparing data transmission performance before and after implementing this solution across 10 vehicles in different regions,the results show that the asynchronous vehicle-to-cloud data transmission architecture significantly improves data integrity and markedly reduces the impact of signal strength variations.The proposed architecture demonstrates notable effectiveness in enhancing data transmission quality and improves the adaptability of vehicle terminals to varying communication network conditions.
