Abstract:
A control unit (1) for operating the peripheral instruments of a vehicle comprises a control element (3) with a connected monitor screen (5). The control element is formed by a gear lever (7) for operating a vehicle gear box. The gear lever (7) can be moved between several positions (9), which correspond to different gear ratios in which the gears can be changed. The gear lever (7) can be moved in a limited area (11) around any position (9), so that moving the gear lever operates the peripheral instruments. The control unit (1) also comprises vibration devices (27) that can vibrate the gear lever (7) during its operation. Vibrating the gear lever in different ways allows the user to feel when a switch is made between peripheral instruments and when functions of peripheral instruments are selected or set.

Abstract:
A driving system 1 comprises a drive source 3 with an output drive shaft 5 which can be coupled via a main clutch 7 to a first input 11 of a transmission 9. This main clutch is arranged as a friction clutch which is closed if it is not operated. The transmission 9 further has a second input 31 which can be connected via a further clutch 33 to an intermediate shaft 35 which is connected to the drive shaft 5. The further clutch is also a friction clutch, but which is open if it is not operated. The first gearing 25 is arranged as a lock up clutch and can be switched to a first state in which it connects the two inputs together and a second state in which it connects the first input to the gear train 19. If this first gearing is not operated, it will maintain the state it had before that.
