摘要
文章介绍了ESP HIL湿式台架和自动化测试管理系统构建及应用。台架由dSPACE测控系统、ESP系统机电液零件、车辆动力学模型和系统仿真模型等构成,实现了ESP系统开闭环测试;自动化测试管理系统基于dSPACE SYNECT开发集成,实现了测试脚本创建、测试过程执行和测试报告输出全流程自动化。以ESP附加功能中的坡起辅助(HSA)功能测试实例介绍了自动化测试的应用,有力支持了ESP系统开发验证,显著提高测试效率和覆盖率,保证测试的精确追溯性,是一套有效的技术解决方案,具有较好的行业推广性。
This paper introduces ESP HIL wet bench and automatic test management system. The bench is composed of dSPACE measurement and control system, electro-hydraulic parts of ESP system, vehicle dynamics model and system simulation model, which realizes the open and closed loop test of ESP system. The automated test management system is based on the development and integration of dSPACE SYNECT, which realizes the automation and test management of test script generation, test implementation and result output. The application of the system is demonstrated with an example of hill start assistant (HSA) function test in ESP additional function. It strongly support ESP system development and test. It is a very effective technical solution, which can improve test efficiency and coverage, ensure the accurate traceability and good promotion.
