Abstract:
1. A method of operating a motor vehicle with an automated gearbox ( 1 ) which is connectable, via a clutch ( 2 ), to a prime mover ( 3 ), and an output rotational speed of the gearbox ( 1 ) is detected by sensors and assessed for plausibility by comparison with an arithmetic mean value of sensor-detected rotational speeds of rear wheels ( 7 , 8 ) of the motor vehicle, upon a failure of at least one of both generated signals ( 20 , 21 ) of rotational speed sensors ( 18 , 19 ) of the rear wheels ( 7 , 8 ), the arithmetic mean of sensor-detected rotational speeds of front wheels ( 9 , 10 ) is used for checking the plausibility of the output rotational speed of the gearbox ( 1 ), and upon detection of significant differences between the arithmetic mean value of the rotational speed sensors of the front wheels ( 9 , 10 ) and the output rotational speed of the gearbox ( 1 ), at least one of: preventing the gearbox ( preventing the clutch (
