Abstract [en]

Driving a car gives us a certain feeling. Driving another car returns a very differentexperience. If we could drive with closed eyes, we could nonetheless explain which vehicle itwas we were sitting in. Not only are there differences between sports cars and transporters orlimousines and trucks, but also it is possible to feel the different sensations from drivingtrucks of different manufacturers. It depends on the seat, the sitting position, the view, thesound, the performance, the brakes - and the steering feel.There are many ways how to describe a vehicle's steering feel. There are ISO-standards, suchas ISO/TS 20119 and ISO 14792 that generate characteristic values, there are subjective testsof automotive magazines, and there are opinions of test and race drivers. But exactly there,between the pure objective tests and the subjective impressions that are difficult to describe,exists a gap. This relationship between instrumentally measured numbers and nearlyindescribable feelings has not been fully investigated yet. With a better understanding of thecorrelation between objective values and subjective experience, it may be possible to find ananswer on which parameters can manipulate the feelings.This paper is on an investigation about finding a correlation between instrumental values(values measured by instruments or calculated from those) and non-instrumental values(values obtained by human impressions). The idea is to use drivers as human measuringgauges and let them measure impressions in their own words.Thus, in order to gather a standardized answer that can be evaluated, a questionnaire wasdeveloped. For this questionnaire the most important consideration was to facilitate the testdrivers with their own languages. Therefore, the questions were developed in the test drivers'native language. The characteristic words were chosen corresponding to the results of adouble interrogation process.When people express their feelings like they are accustomed to do, they will utilize a libraryof expressive words instead of numbers. Thus the measuring results will have that character,too. By using the semantic differential method, expressions can be translated into numbers.The semantic differential method is a well-known method especially in psychoacousticswhich allows people describe how noise sounds to them. With this kind of evaluation - valueassigning procedure - a list of parameters comes to existence similar to that containing theinstrumental values. To explore the relation between the instrumental and non-instrumentalvalues, statistical methods are used.

Abstract [en]

“If touching is not a single perception but a plural, then its objects are a plurality, too.” (Aristotle)

For investigating steering feel, a very important part is how to measure what people feel. The hypothesis in the present research work is that steering feel, as perceived by human beings, can be allotted in dimensions. The steering feel of a certain vehicle can then be seen as a point in a space with multiple orthogonal dimensions. The aim is to find the dimensions that people use to perceive and describe steering feel, in order to define this non-instrumental space. This article describes two modes of evaluation, a manual mode anda mathematical mode using the statistical method of multidimensional scaling. Applying these modes, it has been possible to extract nine dimensions describing the steering feel of road vehicles.

2011 (English)In: Vehicle System Dynamics, ISSN 0042-3114, E-ISSN 1744-5159, Vol. 49, no 12, 1837-1854 p.Article in journal (Refereed) Published
Abstract [en]

There have been several investigations to find out how drivers experience a change in vehicle-handling behaviour. However, the hypothesis that there is a correlation between what the driver perceives and vehicle-handling properties remains to be verified. To define what people feel, the human feeling of steering systems was divided into dimensions of perception. Then 28 test drivers rated different steering system characteristics of a semi-trailer tractor combination in a moving base-driving simulator. Characteristics of the steering system differed in friction, damping, inertia and stiffness. The same steering system characteristics were also tested in accordance with international standards of vehicle-handling tests resulting in characteristic quantities. The instrumental measurements and the non-instrumental ratings were analysed with respect to correlation between each other with the help of regression analysis and neural networks. Results show that there are correlations between measurements and ratings. Moreover, it is shown that which one of the handling variables influence the different dimensions of the steering feel.
