Subjective Comfort Evaluation using Simpack
Comfort is becoming the key performance attribute for vehicle dynamics: the driving task is increasingly becoming automated and this is allowing drivers to value how relaxed and comfortable they feel in the vehicle. However, comfort development is still a big challenge: it requires a driver to feel and validate high fidelity prototypes, prototypes that must typically have a high level of maturity and are therefore usually only available at the later stages of vehicle development. IDIADA and Toyota Motor Europe (TME) have been collaborating on one solution: that of taking the development of ride comfort to a virtual environment using TME’s Simpack vehicle models and IDIADA’s dynamic driving Simulator. Virtual ride comfort development requires a complex high-fidelity vehicle model capable of running in real-time, and we will go through TME’s modelling process on Simpack to achieve a such a model with enough fidelity to evaluate comfort. We will also go through its integration on IDIADA’s state-of-the-art driving simulator capable of replicating accelerations with high amplitude and frequency response in all directions. The process is aimed at significantly cutting the physical development of prototypes whilst at the same time maintaining the same level of performance as that of real testing. Subjective feedback of professional drivers confirms that a rich and complex ride can be felt using TME’s vehicle models coupled with IDIADA’s simulator, especially when driving on IDIADA’s high-definition road models.
