摘　　要：利用载波通信技术可通过汽车电力线实现汽车ECU之间数据传输。通过在XML6796E1G金龙大客车上进行实验,在0～10MHz频段用矢量网络分析仪研究客车在静止和运行情况下载波通信信道的传输特性。实验表明,汽车电力线载波信道具有时变性,但在频率高于5MHz时,时变性不明显。By utilizing carrier communication technique, the data transmission between various electronic control units （ECUs） can be realized through the power lines in vehicle. An experiment is performed on a King Long bus with a vector network analyzer to study the transmission characteristics of the carrier communication chan- nel at a frequency range of 0 to 10MHz under both stand still and operation conditions of vehicle. The results show that the transmission characteristics of the carrier communication channel vary with time when the frequency is lower than 5 MHz.
