Abstract:
1. A method for preventing engagement of an impermissible speed in an automated gearbox with a gear-switching member that can be moved along a gear-selection speed range and out of said gear-selection speed range into a particular gear-step speed range, selected from a plurality of gear-step speed ranges, comprising the steps of: (a) acquiring the particular gear-step speed range in which the gear-switching member is moved; (b) acquiring a momentary vehicle speed; (c) checking whether the particular gear-step speed range is permissible relative to the momentary vehicle speed; (d) triggering a gear-switching actuator upon finding the particular gear-step speed range is impermissible; and, (e) triggering a fault reaction upon the triggering of the gear-switching actuator toward a setting of the plurality of gear-step speed range that is recognized as impermissible.
