The invention provides an automobile communication device, and relates to an automobile bus communication device. The invention solves the problem that in the prior art, an automobile bus is poor in integration. The automobile communication device comprises a CAN line, a pin line and a K line which are used for automobile equipment communication, wherein the CAN line, the pin line and the K line are respectively communicated with the same FPGA circuit through a transceiver circuit, and the FPGA circuit is communicated with an upper computer. According to the invention, the FPGA is used for replacing a host to realize communication of each bus of the automobile, so that the resource occupation of the host is reduced, and the communication speed and reliability are improved. Besides, the FPGA circuit is uniformly connected with an upper computer through a PCIE serial bus to realize uniform management and coordination of the bus. The K line and the lin line are unified into one K line/linline channel, so that the FPGA circuit achieves the purpose that a pair of signal ends can communicate with the K line and the lin line, and can be freely switched to K line or lin line communication.
本发明提供了一种汽车通信装置,涉及一种汽车总线通信装置。它解决了现有技术中汽车总线集成性差的问题。本汽车通信装置,包括汽车设备通信用的CAN线、lin线、K线,所述CAN线、lin线、K线分别通过收发器电路与同一FPGA电路通信,FPGA电路与上位机通信。本发明利用FPGA代替主机实现对汽车各总线的通信,这样不但减轻主机的资源占用也使得通信速度及可靠性得到提高。FPGA电路通过PCIE串行总线统一与上位机连接,实现对总线的统一管理与协调。通过将K线与lin线统一为一个K线/lin线信道,从而使得FPGA电路实现一对信号端即可与K线通信又可与lin线通信的目的,并可自由切换为K线或lin线通信。
