Abstract
In the last years the automotive industries have been increasingly focused on developing new strategies to overcome the current environmental problems caused by particulate materials expelled by combustion. By optimizing the fuel consumption of engines by decreasing the expulsion of these particles, this is one of the main research focuses of the industry today, through the development of environments for the design and performance testing of control strategies applied to engines, as well as the design of virtual models of engine management meshes that represent a real engine. This paper describes the implementation of a Hardware-In-the-Loop (HIL) test platform to evaluate the algorithms implemented in the Electronic Control Unit (ECU) and validate the AFR air/fuel ratio dynamic model. The proposed HIL platform consists of the implementation of control strategies embedded in the FLEXECU that executes the control strategies for AFR optimization and obtain a desired stoichiometry and a virtual engine model that represents the dynamics of the AFR model. This engine model is based on the VW EA211 TSI and presents a good level of correlation with the real engine. For this implementation, different computational tools such as ASCET, INCA, LABCAR and MATLAB were used to design the FLEXECU control algorithms and to onboard the dynamic model to be controlled. These tools have been widely used by researchers and the automotive industry in the design, testing and refinement of engine control algorithms. This paper proposed an effective way to design and evaluate the performance of engine control software. The study emphasized the importance of testing engine control software under realistic conditions to obtain more accurate and representative results. Overall, this study provides valuable information on the implementation of test platforms for engine control software, especially for small displacement turbocharged engines, which can be used to improve the design and performance of internal combustion engines toward greater efficiency and sustainability
