Operational device for menu-controlled functions of vehicle

摘要

The device (1) allows positioning of a cursor on the surface of a video display screen by horizontal movement (10) of an actuator (9) along a cross-bar (8) which slides (11) within a guide (6) in the edge of a frame (7). The movement is sensed by an endless toothed belt and converted into rotation about the shaft of the guide. An electric motor detects the rotation and produces a positioning command for the cursor. The sliding crossbar can also be moved vertically to give a tactile signal to the operator that defined positions have been attained.
