摘　　要：汽车总线数据通信技术已经得到了广泛应用,目前这些总线都需要采用专门的数据线束,这将增加汽车的制造成本、维护难度,并给汽车内的数据传输带来不稳定的因素;汽车电力载波总线数据通信技术的研究正快速取得进展,该方式在不增加汽车内的线束的基础上实现汽车内ECU模块间的数据传输和共享;就如何设计和实现该总线的关键技术进行了相关的研究,研究结果表明在汽车内利用汽车线束进行电力线束载波通信是可行的,具有广泛的应用前景。Based on the computer net and fieldwork control technology, specially developed for the data transmission in automobile, auto- mobile data bus has been developed. Those data buses need special data lines, and the ECUs in automobile have different requirements on data transmission, several data nets are needed in one automobile. This will increase the cost and difficulty to manufacture and maintenance. So in this research a new data transmission method is put forward , data transmission by power line in automobile. This method can realize data sharing between ECUs in automobile without increasing data lines.
