查询词典 speed test

According to the calibration information, Research and development status of automotive bus network and automotive calibration system is studied and the research significance is generalized. First of all, the collectivity precept for calibration system is designed, the calibration platform is set up based on the XCP Protocol and the calibration object is CAN bus network simulation ECUs. Then how to create the calibration system based on Ethernet and Series communication is expatiated, the communication way from computer to ECUs is introduced and the calibration system is tested. Then how to create the calibration system based on CAN bus communication is expatiated, the design and the interface programme are introduced and the calibration system is tested. At last the platform is used to calibrate the CAN bus network simulation system to regulate the simulation system's topology and communication speed to test the communication protocol's feasibility.
