The invention relates to an intelligent tractor network system which comprises a vehicle body BCAN bus, an information ICAN bus, a chassis CCAN bus and a power PCAN bus which are in signal connection with a central gateway, the communication rate of the vehicle body BCAN bus and the communication rate of the information ICAN bus are set to be 250K bps, and the communication rate of the chassis CCAN bus and the communication rate of the power PCAN bus are set to be 500K bps. The network nodes with the communication rate of 500K bps comprise an engine control system (EMS), a transmission control unit (TCU), a hydraulic retarder random access memory (RAM), an anti-lock braking system (ABS)/EBS, an air bag suspension ECAN, an automatic emergency braking system (AEB) and an electronic parking braking system (EPB). According to the invention, through optimizing the network topology, reasonably distributing the load of each network segment and improving the communication rate, the intelligent and networking configuration upgrading requirements of the whole vehicle can be met.
