Build-up of customized test automation solutions for efficient verification of chassis systems in vehicle HILS

Chassis control system should be verified and analyzed with many test scenarios by test engineer within the given time period prior to real vehicle level testing. As a result, test automation plays very important role in testing of chassis ECUs. Test automation system by current software provider cannot be modified by user and has some restrictions. This paper describes newly customized test automation solutions and the proposed automation method is introduced. First of all, the management templates for test cases are designed and parsed by customized test automation tool. And then by using this tool, test scripts which are utilized to manage the test variations and to enable test automation are created. In addition, the generation of tailored test report is automatically or manually conducted right after the selected variations by the test engineer are carried out. Hence, proposed solutions show the efficiency and improvement for testing of chassis ECUs and save the verification time and resource.
