Abstract

A method for operating a motor vehicle with an automated gearbox (1), which can be connected, via a clutch (2), to a prime mover (3). The output rotational speed of the gearbox (1) is detected by sensors and evaluated for plausibility by comparison with an arithmetic mean value of sensor-detected rotational speeds of the rear wheels (7, 8) of the motor vehicle. It is also possible to determine plausibility, using the arithmetic mean of the sensor-detected rotational speeds of the front wheels (9, 10), in case of a failure of at least one of both generated signals (20, 21) of the rotational speed sensors (18, 19) of the rear wheels (7, 8) for checking the plausibility of the output rotational speed of the gearbox (1).
