Abstract

The invention pertains to a motor vehicle with overspeed protector. The clutch in the power train of the motor vehicle can be operated in dependency upon the engine speed in such a way that it is disengaged or operates with slip when the engine speed exceeds a preselected limit while the clutch is engaged. The threshold value of the engine speed is ascertained on the basis of the prevailing (instantaneous) engine speed and the prevailing (instantaneous) or desired increase of transmission ratio. Gear shifting errors and overspeeding of the vehicle are thus prevented in a manner which is more reliable than by following prior proposals.
