Evidence for a fundamental property of steering
Paper i proceeding, 2014
In this paper, a general and fundamental property of steering is demonstrated: It is shown that steering corrections generally follow bell-shaped proﬁles of steering rate. The ﬁnding is strongly related to what is already known about reaching movements. Also, a strong linear relationship was found between the maximum steering wheel rate and the steering wheel deﬂection, something that indicates a constant movement time for the correction. Furthermore, by closer examination of those corrections that cannot be described by a single bell-shaped rate proﬁle, it was found that they typically can be described using two or, in some cases three or four, overlapping proﬁles, something which relates to superposition of motor primitives.
