Control device for a gearbox, in particular for a motor vehicle gearbox, with a system for identifying the engaged gear

摘要

The control device comprises an elongated mechanical transmission member (10; 110) interposed between the gearbox and a control member (100) for transmitting to the gearbox the commands imparted through the control member, in such a manner that the gear engaged by means of the gearbox is linked to the linear position of the transmission member (10; 110). The transmission member (10; 110) includes a rigid end portion (14; 114). The device is provided with a position sensor (26; 126) comprising a movable reference element (28; 128), the movement of which is connected to the movement of the rigid end portion (14; 114), and a stationary detection element (30) for detecting the position of the reference element (28; 128). The reference element (28; 128) is connected to the rigid end portion (14; 114) and spaced apart from it. Preferably, the position sensor is a linear position sensor (26) arranged to detect the linear position of the reference element (28).
