摘要

1. A drive train with a selection device ( 4 ) for the selection of driving mode ranges of an automated manual transmission or of an automatic transmission for a motor vehicle. 2.1. Known selection devices which are designed as selector levers in the region of the vehicle tunnel or as steering column gearshifts occupy an inner space and require additional distances to be covered by the driver's hands which normally rest on the steering wheel. Furthermore, the selector lever and the steering column gearshift project into the interior of the passenger cell, with the result that unwanted faulty operations are possible. 2.2. According to the invention, a selection device ( 4 ) for the selection of driving mode ranges is proposed, which is arranged on the steering wheel ( 1 ) of the motor vehicle and, for operation, is moved rotationally about the steering wheel rim ( 3 ) of the steering wheel ( 1 ) and/or along the steering wheel rim ( 3 ). Moreover, the selection device ( 4 ) can be displaced along the steering wheel rim ( 3 ) into a position for a favorable grip and be designed as a switch or push button or as a combination thereof. 2.3. The invention is suitable particularly for the selection of driving mode ranges of an automated manual transmission or of an automatic transmission.
