ECU Configuration Tool Based On AUTOSAR

AUTOSAR represents the trend of automotive electronics industry development. ECU configuration is an important step within the AUTOSAR system development process. This paper completes an ECU configuration tool for the ECU configuration process of the AUTOSAR methodology. Since there is a large number of configuration items in the step and the requirement of further possible upgrade, we propose an automatic GUI generation method in the development of configuration tool to avoid the disadvantages of manual GUI development such as low efficiency, weak scalability and non-uniform GUI styles. This paper's main work includes the following aspects:Firstly, to discuss of XML files that conforms the AUTOSAR schema as well as ECU parameter definition format.Secondly, the design of the class model for ECU parameter. The information of ECU parameter definitions are converted into the class models so the instances derived from the class models can be accessed. The class models are imported into the ECU configuration tool and based on the model, ECU configuration tool is able to get the parameter definitions and generate the GUI.Thirdly, the implementation of the ECU parameter class models generation tool. In it we designed class model generation factories to perform model generation work in accordance with the parameter definition types.At last, the implementation of the ECU configuration GUI generation. We designed the model analyzer to parse the information annotated in the class model and corresponding widgets factories are invoked to generate the appropriate GUI for users to configure.
