ABSTRACT:
A process for preventing the engagement of an impermissible speed in an automated gearbox with a gear-switching member, which can be moved along a gear-selection speed range and out of it into speed step ranges containing the following steps: acquiring the speed step range in which the gear-switching member is moved; acquisition of the momentary vehicle speed; checking as to whether the speed, belonging to the particular speed step range related to the momentary vehicle speed, is permissible; acquisition of the triggering of a gear-switching actuator in case of an impermissible speed; and, triggering of a fault reaction upon the activity of the gear-switching actuator toward the setting of the speed that is recognized as impermissible. A device for implementing the method is also disclosed.
