Abstract
In order to improve the prediction accuracy of noise and vibration performance of vehicles with two-motor hybrid systems during the performance design phase, a 1D system model that can calculate the driving conditions of the vehicle was developed. In addition, an interior noise model was developed that can reproduce power unit noise/road noise/wind noise in an integrated manner. By passing engine speed, engine torque, and vehicle speed from the 1D system model to the interior noise model and coupling them, it is possible to predict the interior noise in conjunction with the power unit control study.
