本文以ABS采集系統(tǒng)為基礎,利用嵌入式技術設計了以SD卡為存儲介質的駕駛行為再現(xiàn)存儲系統(tǒng),對ABS的數(shù)據(jù)進行讀寫操作。本系統(tǒng)采用了目前通用的通信方式及SD卡對數(shù)據(jù)進行存儲,設計了基于嵌入式的硬件平臺,而在軟件設計方面采用了實時操作系統(tǒng), 為上層運用軟件開發(fā)提供很好的軟件運行環(huán)境, 同時簡化了底層軟件的開發(fā)。最后,系統(tǒng)在實驗中表現(xiàn)出功能適用、性能穩(wěn)定的特點,達到了駕駛行為再現(xiàn)數(shù)據(jù)存儲的目的。

Abstract: In this paper, the driving behavior reconstruction storage system based on SD card and the ABS acquisition system is designed by using embedded technology and with this storage system, the ABS data can be read and written. Moreover, the current communication mode and SD card facility are applied to the storage system, and the hardware platform is designed. In the
software design, the real time operation system is adopted for the upper stratum usage software explorer to provide a good software operation environment, simplifying the explorer of under stratum software. Finally, the storage system manifests the characteristics of function applicability and steady performance, and the driving behavior reconstruction data storage is accomplished.
Key words: driving behavior reconstruction, embedded system SD card, storage
