摘　　要：汽车内部网的应用和无线车载数据的传输受到越来越多的重视。从应用的角度详细描述了车载CAN/GPRS(Controller Area Network/General Packet Radio Service)网关的硬件设计和软件设计。同时,针对目前将CAN设备驱动实现为字符设备驱动带来的缺点,提出了将CAN设备驱动实现为网络设备驱动,使用Socket进行CAN通信。最后,通过测试验证Socket CAN通信和GPRS无线联网。The application of automobile internal networks and the transmission of wireless vehicular data are attracting growing attentions.In terms of the application,we expatiate on the designs of hardware and software of CAN/GPRS vehicular gateway in the paper.Meanwhile,in light to the drawback brought about by implementing CAN device driver to the character driver,we propose to implement CAN device driver to the network devices drivers and using Socket to conduct CAN communication.At last,we validate Socket CAN communication and GPRS wireless internet by test.
