Software in the Loop (SiL) project, a collaboration between Bosch and FPT, focuses on developing a virtualized environment for automotive testing, specifically for engine development. This environment encompasses the complete virtualization of essential components such as Engine Control Unit (ECU), networks, actuators and engine management. The primary aim is to create a simulation platform that offers improved flexibility and speed compared to existing models, with the ultimate goal of accurately replicating vehicle test results in a virtually simulated environment.
The project is structured into two key stages: software development and performance evaluation. During the software development phase, the engine, ECU, connectors, and actuators are operated together in a closed loop, with basic software enhancements and calibration changes made to mirror the typical behaviour of the engine system. The calibration adjustments and engine performance measurements are carried out using the INCA tool developed by ETAS. In the subsequent performance evaluation stage, the SiL environment is provided with the latest vehicle test performance results as inputs, and the simulated performance is meticulously measured and analyzed.
The measurement framework for the SiL environment is designed to encompass visual trend comparison, statistical metrics, and the ability to consistently recreate results with multiple iterations of the same input. This comprehensive approach ensures a thorough evaluation of the simulated performance in comparison to actual vehicle test results.
Upon the completion of this stage, the SiL environment demonstrates the capability to replicate the fundamental functionality of the engine testing procedure and performs virtual calibration tests and changes that closely mirror those conducted on the actual vehicle. The benchmarked performance serves as a foundational reference point for subsequent stages of the project.
In the next stage, efforts will be directed towards aligning the software setup of both the vehicle and the SiL environment to ensure they run the same software version in accordance with EURO 7 standards, a critical requirement for compliance and validation. This alignment will enable a more accurate comparison and validation of the SiL environment against the actual vehicle performance. The benchmarked data from this stage will provide a necessary starting point for the subsequent phases of the project.
