Device and method for detecting the position of a shift fork of a manual transmission

摘要

The invention relates to a device (30) with a Hall sensor device (10) for detecting the position of a shift fork (7) in a transmission (1), wherein the shift fork (7) with a piston rod (6) one in a shift cylinder (3) axially movably guided switching piston (2) is operatively connected and in an axially displaceable on a transmission shaft (9) arranged sliding sleeve (8) engages to move this sliding sleeve (8) for engaging or disengaging a gear ratio of the gearbox (1). Here, it is provided according to the invention that at least one of the adjustable actuators switching piston (2), piston rod (6) or shift fork (7) a magnet (13) is arranged as a signal generator that a relative to the magnet (13) fixedly arranged 3D Hall sensor (11) is present as a signal receiver, by means of which a magnetic field generated by the magnet (13) is spatially detectable that the 3D Hall sensor (11) is connected to an electronic control unit (31), and that the Control unit (31) is designed such that with this from the respective relative position between the magnet (13) and the 3D Hall sensor (11) the current position of the shift fork (7) determinable and as a signal is available, wherein linear Movements, rotational movements and / or pivotal movements of the relevant actuator (2, 6, 7) are considered.
