| Abstract: | The gateway of vehicular CAN bus network is the device connecting each network segment. Its main function is to realize data interaction between electronic control units in each network segment. In order to meet the requirements of real-time and stability of CAN bus, gateway has strict requirements on delay time and frame loss rate of signal forwarding. CANoe is a powerful CAN bus design and test software. It can be used to design a test model with comprehensive functions and realistic simulation environment. According to the actual test data, it can be calculated. The CANoe-based CAN bus gateway test model can accurately test the routing delay time and frame loss rate of gateway routing messages. |
