METHOD FOR CONTROLLING THE DRIVING OPERATION OF MOTOR VEHICLES OR OTHER VEHICLES The present invention relates to a method for controlling the driving operation of motor vehicles or other vehicles according to the preamble of Patent claim 1. Methods for controlling the driving operation of motor vehicles are known, according to specific driving conditions which are detected by way of rotation sensors and evaluated in a control unit to control ABS, ASC or similar systems. Such rotation sensors provide the number of revolutions but not the corresponding rotational direction. If the rotational direction of the wheels or specific sul>-assemblies of the power train is needed, it must be calculated by way of a determination algorithm based on different values in a relatively complex manner, with this as a background, it is the object of the present invention to furnish a method for controlling the driving operation of motor vehicles or the like in which a complex determination algorithm for the calculation of the relevant number of revolutions can be ascertained. The realization of this object results from the characteristics of the main claim, whereas advantageous refinements and furtlier developments of the present invention may be derived from the dependent claims. Rotation sensors as such are known, but they have so far not been used for controlling the driving operation of motor vehicles. The present invention is based on the knowledge that the use of rotation sensors not only make complex determination algorithms for the determination of the number of revolutions dispensable, but facilitate additional useful functions for the operation of a motor vehicle. Thus, the present invention is based on a method for controlling the driving operation of motor vehicles or the like, for example wheel and/or track vehicles, according to which specific driving conditions are detected by way of rotation sensors that are assigned to individual wheels and/or sub-assemblies in the power train, are evaluated in a control unit and are converted into commands for specific functions of the vehicle or waming signals. In the present description, warning signals are understood to be general optic or acoustic signals as well as visual displays. To realize the objective posed, this method additionally provides that rotation sensors are used as rotational direction sensors. The present invention takes advantage of the further knowledge that the information about the cun^ent rotational drrection also implies knowing whether there is rotary motion at all. The information "there is a rotary motion" is usually derived from the information on the number of revolutions. If the number of revolution equals zero, there is not rotary motion. If the number of revolutions is larger than zero (or larger than a defined threshold value), there is rotary motion. When using rotation sensors, this determination whether there is rotary motion or not can be replaced by the determination whether a rotary motion was detected or not When using rotation sensors according to the present invention, functions for which the knowledge whether there is rotation or not is relevant, as well as functions for which the knowledge of the current rotational direction is relevant, can be implemented- At this point, some expressions used in the present description should be defined in more detail: the expression "driving status" describes the motion of the vehicle up to standstill. It thus comprises the statuses "vehicle driving", "vehicle stopped", "vehicle driving forward" and "vehicle reversing"; the expression "operating status" describes the motion of individual elements of the vehicle, comprising statuses such as ''rotating wheel", "non- rotating wheel", "rotating sub-assembly", eta; the expression "driving conditions" should be understood as the conditions specified by the driver according to the desired driving scheme, for example "accelerator activated", "brake not activated", "switched gear", etc; the expression 'stop condition" should be understood as the conditions specified by the driver according to the desired stop scheme, for example "brake activated", "accelerator not activated", etc. According to a variation of the method, it is provided that the current rotational direction of at least one wheel and/or one sub-assembly in the power train is detected and evaluated for the determination of the operating statuses "rotating wheel or sub-assembly" or "non-rotating wheel or sub-assembly", and/or of the driving statuses "vehicle driving" or "vehicle stopped". As already explained in the present case, it is not the current rotational direction that is relevant, but the determination whether there is rotary motion or not. Taking advantage of these properties, it is provided that on determination of the driving status "driving vehicle" and the simultaneous presence of the specified stop conditions (e.g., a certain brake pressure; accelerator not activated), the brake pressure is increased automatically until reaching the driving status "stopped vehicle" or the emission of a warning signal. This way, the vehicle is either stopped automatically or the driver is alerted so that he may take measures to secure the vehicle and prevent rolling when stopping is desired. According to the present invention, the curent rotational direction of various driven wheels is detected where, on determination of the operating status, "at least one rotating wheel and at least one non-rotating wheel" and the simultaneous presence of specified driving conditions (e.g., gear engaged; accelerator activated), a traction control system is activated, which redistributes the driving power of the spinning wheel to the fixed wheels in the usual way, Simllariy, the current rotational direction of various braked wheels can be detected where, on determination of the operating status, "at least one rotating wheel and at least one non-rotating wheel" and the simultaneous presence of specified driving conditions (e.g., gear engaged; brake pedal activated), an anti-locking system is activated, which reduces the brake pressure on the locking wheel in the usual way until it rotates again. In a further embodiment of the present invention, the current rotational direction of both wheels of a pair of driven wheels is detected where, on determination of the operating status "at least one rotating wheel and at least one non-rotating wheel" and the simultaneous presence of specified driving conditions {e.g., gear engaged; accelerator activated), a differential lock is automatically connected, A further advantageous use of the method of the present invention results for vehicles with a lifting axle and/or raising axle. In this case, It is provided that the current rotational direction of at least one wheel of the lifting axle is detected and that on determination of the operating status Votating wheel of the lifting axle" as well as the presence of the driving condition "lifted lifting axle" and/or on determination of the operating status "non-rotating wheel of the lifting axle" and the driving status "driving vehicle" as well as the simultaneous presence of the driving condition "lowered lifting axle", a warning signal is emitted. This allows checking whether a lifting axle was actually lifted or lowered. If the sensors on the wheels of the lifting axle Indicate that there is no rotary motion, the lifting axle can be assumed to be lifted while driving. The comparison with the nominal condition, that is, with the driving conditions specified by the driver, provides confirmation or information on any malfunction. As already mentioned above, there are functions to which the cun^ent rotational direction of the wheels or sub-assemblies in the power train are relevant. This is provided by the employed rotation sensors according to the present invention. Taking advantage of these propertieSp a further embodiment according to the present invention provides that the cun-ent rotational direction of at least one wheel or one sub-assembly in the power train is detected and evaluated for the determination of a driving status "vehicle driving forward" or "vehicle reversing" and/or "wheel or sub-assembly rotating forward' or "wheel or sub-assembly rotating backward". This function allows checking whether the motion of the vehicle corresponds to the driving conditions specified by the driver or not. in the latter case, corresponding countermeasures can automatically be started or warning signals be generated. Hence, a further refinement of the present invention provides that if there is a specific driving condition (for example^ forward gear engaged and/or reverse gear engaged) and a driving status that opposes one of these driving statuses (for example, vehicle reversing and/or vehicle driving forward) is determined, a brake is automatically activated. If the driver of a vehicle selects a fonward gear and wants to start the vehicle and a rotation sensor detects the vehicle is rolling backward, a brake that prevents this can be activated. On the contrary, if the vehicle starts rolling in the direction desired by the driver, an activated brake could be released- Rolling down a mountain would be possible this way. In contrast to the function described above, a further embodiment of the present invention provides that on determination of a certain driving status (e.g.,, vehicle driving forward and/or vehicle driving backward) without the presence of a corresponding driving condition (e.g., fooA/ard gear engaged and/or reverse gear engaged), a brake is automatically activated. If a driver coasts his vehicle downhill, a brake could be activated that would stop the vehicle as soon as a rotation sensor detects that the vehicle is changing direction. When rocking a vehicle free, it is important to detect when a vehicle's motion out of the hole starts rolling in the opposite direction and to react rapidly by switching to the opposite direction or actually contributing to It. According to an embodiment of the present invention, a control function "rocking free" is provided where, on determination of the driving status "vehicle stopped" after Vehicle driving forward", the forward gear is automatically switched to the reverse gear, and with the driving status "vehicle stopped" after "vehicle reversing" a fonvard gear is engaged. On the other hand, a simplified procedure provides that a control function "rocking free" Is provided in which, on determination of the driving status "vehicle stopped*' after an active fonward motion and/or backward motion, the vehicle clutch is disengaged and on determination of the driving status "vehicle stopped" after a respective passive motion in the opposite direction, the vehicle clutch is again engaged for an active motion phase. The function "rocking free" is preferably discontinued automatically and thus ends when the vehicle has covered a predetermined distance in one direction, that is, does not stop immediately. The expression "active" indicates that there is a drive connection to the engine, whereas the expression "passive" indicates that the vehicle is rolling powerlessly. A critical and in some situations difficult maneuver is driving in reverse. Therefore, modern vehicles offer functions that are activated especially in reverse in order to facilitate this and/or make it more uncritical Such systems are again de-activated on subsequent forward driving. The present invention also offers the possibility of automating these functions. Therefore, it is provided that the driving status "vehicle reversing" and/or '^vehicle driving fonA^ard" is performed automatically for the adjustment of the vehicle relevant to the respective driving direction. Thus, the reverse light, a reverse drive warning signal (e.g., warning lights and/or acoustic signal), a reverse drive camera or the like could be activated in reverse. At present^ engaging a reverse gear is generally the necessary condition to be detected by a related sensor. But the cases in which the vehicle is rolled backwand without engaging a reverse gear are not included. Further functions to facilitate driving in reverse could additionally be implemented, namely, adjusting the rear-view mirror for reverse driving, removing pane blinds and rocking to and fro, folding away and/or retracting parts attached to the bodywork, like spoilers and the like. Upon detection of forward driving, the vehicle could be returned automatically to a status that is appropriate for this driving direction. In multi-axle vehicles, it can occur that on a strong steering impact, e.g.,, when the vehicle Is driving fonA/ard, at least one wheel rotates backward. By detecting the rotational direction of the vehicle wheels this way, such a situation can easily be identified. According to a further development of the present invention, it is provided that on determination of the driving status "vehicle driving forward" and/or "vehicle reversing" and simultaneous determination of the respective operating status "at least one wheel rotating backward" and/or "at least one wheel rotating forwanj", a warning signal is emitted, which calls the driver's attention to the excessively strong steering impact. If rotational directions are detected on the wheels when the vehicle is stopped, this may suggest that the driver is changing the steer angle of the stopped vehicle. In this case it is provided that on determination of the driving status "vehicle stopped'* and the operating state "at least one wheel rotating", a warning signal is emitted. Depending on which wheel is rotating in which direction, the steering direction can be derived. If the rotational direction of one wheel changes, the amplitude of the steer angle can be derived. Excessively large steer angles can be excluded in specific operating situations, when the vehicle has to be rocl
