DESENVOLVIMENTO DE UM MODELO COMPUTACIONAL PARA SIMULAÇÃO E CONTROLE DE TORQUE EM VEÍCULO

This study proposes the development of a computational model for the simulation and control of torque in a vehicle equipped with a nine-speed automatic transmission, operating under con- ditions with a driver and four passengers. To achieve this objective, vehicular data was collected through the On-Board Diagnostics (OBD) system, allowing the identification and analysis of the variables for torque control, such as engine rotation, accelerator pedal position, and the differ- ent torque components. Based on the data analysis, a computational model was developed that integrates closed-loop PID controllers and an ARX model to adjust the torque application. The simulations conducted in the modeling environment demonstrated that the combination of the PID controller model is effective in reducing the discrepancy between the requested torque and the torque actually applied. In particular, the configuration called PIDARX6 showed the best per- formance, presenting a satisfactory mean error (RMSE) relative to the minimum consumption curve, which suggests a significant potential for reducing fuel consumption and improving the vehicle’s energy efficiency. Thus, the developed model contributes to the enhancement of vehi- cle performance, offering a promising tool for improving vehicular systems under real operating conditions
