Developing a Communication between Calibration Tool and Electronic Control Unit Based on CCP Protocol

In the stage of the calibration of electronic control unit of automobile controller, the traditional method needs to connect the calibration tool to the real ECU, which requires high calibration environment. In order to avoid dependence on the real ECU, this paper, through the introduction of the working principle of the communication way of CCP protocol and message format, uses CANoe, which is the product of German company Vector for bus simulation, to develop ECU simulator. In that way, we can realize the calibration of virtual ECU by calibration tool online and improve the efficiency of calibration system development.
