Abstract: A process for the prevention of unintentional gear shifting from a non-friction locked position of a transmission is proposed, which is comprised by an electrical or electronic gear shift control and a friction-locked gear shift or selector device, within the scope of which the requested friction-locked position detected by the electrical or electronic gear shift control is outputted and is displayed to the driver by way of a position display during position shifting from a non-friction locked position, at the latest when the friction-locked gear shift or selector device has reached a position or a range within which it can remain in an automatic lockup, whereupon this position is implemented in the transmission.

Abstract: Servo-assisted gear selection for a vehicle gearbox and gear change controlled by the driver by actuating the clutch, wherein the driver is informed of the selection having been performed in the gearbox by a haptic or tactile signal at the clutch pedal. The signal is transmitted mechanically from an electromagnet to the clutch pedal, or the electromagnet is arranged in the pedal plate of the clutch pedal. The signal generator may also consist of an electromagnet in conjunction with a pressure piston, which acts on the pressure line of the clutch actuating mechanism, or of an electropneumatic valve in conjunction with a differential piston signal generator.
