Abstract: An apparatus is provided for suppressing torque steering in a vehicle in which left/right drive shafts are coupled via outer joints to left/right front wheels. The drive shafts are connected via inner joints to an engine and transmission. The height of the inner joints is set 5-20 mm lower than the height of the outer joints, thus forming tilt angles between the left/right drive shafts and the center axis through the left/right wheels and the outer joint. As acceleration of the vehicle increases, the engine moves upward, thus causing the inner joints to move as well. This upward movement of the inner joints causes the tilt angle formed by the drive shafts to decrease. The specific placement of the inner joints is selected so that the left/right tilt angles reach zero at a predetermined rate of acceleration, which may be the vehicle's maximum rate of acceleration.

Abstract: In a method for operating a drive train for a motor vehicle, a torque is produced by means of an internal combustion engine as a function of an available torque set value signal and transmitted to drive wheels by means of a clutch. With the help of an electric motor, a closing force is applied, with which the clutch is held in a closed position against a restoring force. The electric motor is energized in such a way that a high current is used in the case of a high torque and a lower current is used in the case of a lower torque. The thermal load of the electric motor is determined and a load signal corresponding to the thermal load is produced. The load signal is compared with a load limit signal assigned to a permissible load range. If the load signal deviates from the load-limit signal, the torque of the internal combustion engine is limited.
