ABSTRACT:
The invention provides a method for detecting the wheel rpm values of the nondriven and the driven wheels and for comparing them with one another in order to improve vehicle stability, for example when the driving torque of the engine is too high. A friction clutch located between the drive motor and the wheels in the drive train is disengaged when the rpm of the driven wheels is less than the rpm of the nondriven wheels and the difference between the two wheel rpm values exceeds a given limiting value. The friction clutch is re-engaged when the difference between the two wheel rpm values reaches or falls below a second limiting value.
