Abstract:
1. A device to detect the position of a gearshift lever ( 2 , 2 ′) for selecting a gear setting of a motor vehicle in which the gearshift lever ( 2 , 2 ′) has a ball-and-socket joint ( 20 ), in which a signal transmitter ( 14 ) comprises a magnet that is installed on the gearshift lever ( 2 , 2 ′) by arrangement on or in a ball ( 22 ) of the ball-and-socket joint ( 20 ) with said magnet defining a north-south axis ( 18 ) and a magnet mid-point, and a signal receiver ( 16 ) comprises a triaxial Hall sensor system that is installed at a distance from the signal transmitter ( 14 ), and in which the position of the signal transmitter ( 14 ) relative to the signal receiver ( 16 ) is different in various selectable gear settings, characterized in that the north-south axis ( 18 ) of the magnet ( 14 ) does not run through a mid-point ( 26 ) of the ball, and the magnet ( 14 ) is arranged eccentrically with respect to an axis ( 28 ) defined by a shortest distance between the ball ( 22 ) and the Hall sensor ( 16 ) and running through the mid-point of the ball ( 22 ).
