This work presents the evaluation of an experiment on the relationship between driver performance and vehicle handling quantities. Both of them are instrumental quantities, however, the former are driver dependent, the latter are only vehicle dependent. A moving base driving simulator was used to examine 16 truck-trailer-combinations. The driving of 28 test drivers in a special developed manoeuvre resulted in characteristic driver performance values evaluated of vehicle system quantities measured while driving. Stationary and dynamical ISO-handling tests resulted in handling quantities. The correlation by means of regression analysis between these driver performance values and the quantities of the ISO-handling tests are presented here as a step towards the mapping of steering feel.QC 20120213</p

On a Method for Generating a Word Pool for the Description of Steering Feel

“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.QC 20101220</p

Finding correlation between steering feel assessments and the driver’s performance using a moving base driving simulator

There is not yet a standardised method to find mutual corresponding subjective and objective measurements. This paper describes how non-instrumental measurements (made by human measurement gauges) and instrumental measurements (made by measuring instruments) can be distinguished in quantities that are dependent of the vehicle, the driver's skills or the driver's individual preferences. Moreover, this paper shows the correlation between instrumental and non-instrumental measurements.QC 20120215</p
