Abstract
Previous studies [1, 2] have described a new analysis technique for objective measurements of passenger car steering systems carried out using the ISO standards [4]. This analysis technique is based on deriving linearised stiffness and damping metrics from the non-linear results typically obtained for vehicles. In this paper, the previous work is extended by carrying out a more comprehensive study of the correlation between these objective metrics and driver subjective assessments using a wide range of vehicles. It is concluded that subjective assessments of on centre steering effort level, response level, friction and delay correlate well in many cases with the proposed objective metrics.
