With the number and complexity increase of electronic control units (ECUs) within the automotive industry, the tests requirement’s stringency also tends to increase, regarding safety, performance and quality, which in turn lead to greater costs and time required to implement and execute these tests. This work presents an integrated and automated workflow to setup, execute, monitor and evaluate a stress test for an electronic stability program (ESP) module, that may also be applied to other ECUs with minor changes. The proposed method consists on the repeated reproduction of several controller area network (CAN) logs, collected from a prototype, production vehicle or even a virtual automobile, into a real-time bench mounted system, that contains the targeted ECU and peripherals components. A Hardware-in-the-Loop (HiL) approach is used to reproduce physical sensors and CAN inputs to the ECU.
