Abstract: Vehicle gateway is at the core of internal communication local area network (LAN) of automobile control. High performance gateway controller plays an important role in the architecture of the vehicle control system. In this paper, according to the design requirements of a passenger vehicle electric power steering system controller, based on CANoe gateway system test of Vector company in Germany, the hardware architecture of the test platform is constructed, its working principle is analyzed, and the CANoe simulation environment is imported, the simulation model is established, and the test program is designed. Finally, the gateway controller is tested on the experimental bench to verify the feasibility of the design scheme, and the results show that the system achieves the desired effect.
