Abstract

An automatic driving position adjustment system and its method are disclosed in which a manual adjustment to a first adjustable component results in the automatic adjustment of a second adjustable component. When the position or angle of a seat or other first adjustable component is adjusted by the driver, a detector measures the relative change in position or angle of the first adjustable component. A controller computes the required change in position or angle of the second adjustable component by multiplying a prescribed coefficient by the relative change in position or angle of the first adjustable component.
