Abstract
Engine design and its calibration phases are challenges that involve the development of engines, considering that it demands a lot of time and investment from the manufacturer companies. Drive-in-motion simulators try to reproduce the most reliable behavior to the driver according the accuracy level demanded in order to predict vehicle response towards dynamics and driving sensation. This work aims to propose a methodology for evaluating vehicle driveability through a subjective analisys using a Drive-in-motion simulator and an engine model previously developed in AVL-Boost. At first, a 1D engine model was developed to predict the 1.6-liter engine response at WOT. In the DiM simulator model, the original pedal slope was replace by 3 different accelator pedal/engine maps calibrated on-board. Various drivers blind tested the 4 proposed models and evaluated them in relation to fun-to-drive and comfort aspects. The results showed a high level of accordance by the drivers revealing that it is possible to pre-develop a vehicle driveability calibration using a Drive-in-motion simulator to reduce manufacturer vehicle development time and costs.
