This paper introduces a special 'quality' parameter on automotive perspective, i.e. the quality index in order to measure the customer satisfaction with car manoeuvrability In particular, it describes how the characteristic setting curves of a car shock-absorber can be optimized using subjective customer assessment of three categories of perception: handling, steering quality and ride-comfort. These, called manoeuvrability indices, were used to represent the assessment of customer satisfaction with car manoeuvrability The characteristic curves for each shock-absorber setting were defined using parameters which uniquely determined their shape. Subsequent analysis was carried out using simulated experimental design which adopts a numeric model of vehicle simulation thereby enabling experimental costs to be reduced. This analysis made it possible to ascertain which setting parameter values provided the best compromise among the three categories of required performance. A codified method of optimization was then developed. This method, which includes the three categories of perception, will be extended to all new projects. Copyright (C) 2001 John Wiley & Sons, Ltd.
