1. A gear-selection assembly, comprising:
- a vehicle gearbox;
servoassist means operatively connected with said gearbox for shifting gears thereof;
operator-controlled gear-selection means operatively connected to said servoassist means for selecting a gear into which said gearbox is to be shifted;
a clutch pedal depressable by an operator in response to actuation of said operator-controlled gear-selection means to enable shifting of gears by said gear box; and
means responsive to a gearshift performed in said gearbox for generating a haptic signal and applying said signal to said clutch pedal in a form tactilely sensed by said operator while said clutch pedal is depressed, to indicate that said clutch pedal can be released to reengage gears following shifting thereof.

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.
