Softwarový nástroj pro automatizaci reakci řídící jednotky motoru na chybové stavy

Abstract

Since Bosch launched electronic ABS in 1978, on-board automobile electronics have significantly improved. Automotive electronic control units (ECUs) are essential to the electronic architecture of automobiles, allowing them to be controlled and kept in proper working order. In order to automate the post-processing of inter-system validation test results acquired on Hardware-in-the-loop (HIL) test benches, I designed and developed a Python tool for my Diploma Thesis at the Renault Lardy Technical and Test Centre in France. Inter-system tests involve assessing proper communication between the various electronic control units within the vehicle and Hardware-in-the-loop (HIL) benches are testing platforms which employ physical hardware components to mimic real-world interactions, facilitating the evaluation and validation of electronic control units. The ultimate goals of this diploma thesis are to decrease validation times and costs while increasing the quality of new project development for the Renault Group. First of all, I was able to plan the project's progress timetable and organize my work by creating the Python tool's architecture. I was able to develop the many functions that make up the tool in this way. The results acquired by human and automatic test analysis were then identical, except for a few rare occurrences, as revealed by the tool's validation period. Additionally, the tool was made available to my team at the end of the diploma thesis, it confirmed that this automated post-processing tool for HIL bench tests frees up human resources to focus on activities which have a higher added value, including fixing tool-detected mistakes.
