Investigation of a method to extend the use of output data from Scania's Hardware-In-the-Loop simulations: Development of database and search algorithm
Independent thesis Advanced level (professional degree), 20 credits / 30 HE creditsStudent thesis
In the automotive industry, Hardware-In-the-Loop (HIL) laboratories are used for testing vehicle functions and systems. Swedish heavy truck manufacturer Scania recently upgraded its HIL lab resulting in an opportunity to save all data generated by simulations in the HIL lab for post analysis. Thus, Scania wished to investigate the possibility to extend the use of output data by examining a new test method. The new test method was intended to be used for disclosing a type of error that had not been possible to detect prior to the upgraded HIL lab. The proposed test method was to store tests in a database and to run the tests upon output data generated in the HIL lab. The tests which were to be stored in the database existed as scripts written in the programming language Python. In order to insert tests into the database the data had to be extracted from the Python test scripts. The investigation showed the database test method to be feasible in small scale for some test scripts but the results also indicated weaknesses with the method’s setup. Insertion of data, extracted from test scripts, into a relational database showed to be problematic as the data was highly heterogeneous and did not fit easily into relational tables. For future implementations it is suggested that the method incorporates other information sources complementing the test scripts.
