What is claimed is: 1. A method for the error control procedure of an electronic control device (24) of an automatic transmission (6, 8), especially an automated shift transmission, disposed within the drive train of a motor vehicle, wherein the control device in the error-free state produces signals calling for an increase in torques from an engine (4) during a gear shift according to which the torque produced by the engine is controlled, in which method a requested value that is a function of the requested torque is compared to a predetermined limit value and an error signal is produced if the requested value exceeds the limit value. 2. The method as described in claim 1, wherein the requested value corresponds to the sum of the torques requested during a defined period of time. 3. The method as described in claim 1, wherein the limit value is a function of the position of an accelerator pedal. 4. The method as described in claim 1, wherein the comparison occurs only when predetermined operating states are present. 5. A device for an error control procedure of an electronic control device (24) of an automated shift transmission (8) and a clutch (6), disposed within a drive train of a motor vehicle, wherein the clutch is arranged to transmit torque directly from the engine to the transmission, the control device comprises a microprocessor (26) with program memory (28) and data memory (30) connected to sensors (34-50) for the detection of operating parameters of the drive train, said microprocessor is linked to at least one actuator (46, 50) to control a gear ratio of the transmission, and, when predetermined operating states are present, especially during the course of a gearshift operation, in an error-free state produces signals that call for predetermined torques from an engine (4) according to which torque produced by the engine is controlled. 6. The device recited in claim 5, wherein said device is operatively arranged to compare a requested value that is a function of the requested torque to a predetermined limit value and to produce an error signal if the requested value exceeds the limit value. 7. The device recited in claim 6 wherein the requested value corresponds to the sum of the torques requested during a defined period of time. 8. The device recited in claim 6 wherein the limit value is a function of the position of an accelerator pedal. 9. The device recited in claim 6 wherein the comparison occurs only when predetermined operating states are present. 10. A method for the error control procedure of an electronic control device (24) of an automatic transmission (6, 8), especially an automated shift transmission, disposed within the drive train of a motor vehicle, wherein the control device in the error-free state produces signals calling for predetermined torques from an engine (4) under predetermined operating conditions according to which the torque produced by the engine is controlled, in which method a requested value that is a function of the requested torque is compared to a predetermined limit value and an error signal is produced if the requested value exceeds the limit value and wherein the requested value corresponds to the sum of the torques requested during a defined period of time. 11. A system for controlling operation of a drive train, comprising a controller (24), wherein, the drive train includes an engine (4), an automated shift transmission (8), and a clutch (6) and wherein the clutch is arranged to transmit torque directly from the engine to the transmission and wherein the controller produces signals calling for predetermined torques from the engine under predetermined operating conditions according to which the torque produced by the engine is controlled, compares a requested value that is a function of the requested torque to a predetermined limit value, and produces an error signal if the requested value exceeds the limit value. 12. A method for the error control procedure of an electronic control device (24) of an automatic transmission (6, 8), especially an automated shift transmission, disposed within the drive train of a motor vehicle, wherein the control device in the error-free state produces signals calling for requested torques from an engine (4) in a mode of an engaged gear according to which the torque produced by the engine is controlled, in which method a requested value that is a function of the requested torque is compared to a predetermined limit value and an error signal is produced if the requested value exceeds the limit value and wherein the requested value corresponds to the sum of the torques requested during a defined period of time. 13. A device for an error control procedure of an electronic control device (24) of an automated shift transmission (8) and a clutch (6), disposed within a drive train of a motor vehicle, wherein the clutch is arranged to transmit torque directly from the engine to the transmission, the control device comprises a microprocessor (26) with program memory (28) and data memory (30) connected to sensors (34-50) for the detection of operating parameters of the drive train, said microprocessor is linked to at least one actuator (46, 50) to control a gear ratio of the transmission, and, when predetermined operating states are present, especially during the course of a gearshift operation, in an error-free state produces signals that call for predetermined torques from an engine (4) according to which torque produced by the engine is controlled, wherein said device is operatively arranged to compare a requested value that is a function of the requested torque to a predetermined limit value and to produce an error signal if the requested value exceeds the limit value and wherein the requested value corresponds to the sum of the torques requested during a defined period of time. 14. A device for an error control procedure of an electronic control device (24) of an automated shift transmission (8) and a clutch (6), disposed within a drive train of a motor vehicle, wherein the clutch is arranged to transmit torque directly from the engine to the transmission, the control device comprises a microprocessor (26) with program memory (28) and data memory (30) connected to sensors (34-50) for the detection of operating parameters of the drive train, said microprocessor is linked to at least one actuator (46, 50) to control a gear ratio of the transmission, and, when a gear is engaged, in an error-free state produces signals that call for predetermined torques from an engine ( 4) according to which torque produced by the engine is controlled.
