Abstract:
A method for adjusting an output torque of an internal combustion engine in a motor vehicle including at least four wheels arranged on at least two axles and driven by the internal combustion engine, the motor vehicle including a plurality of differentials including at least one transverse differential assigned to one of the at least two axles associated with driven ones of the at least four wheels, the motor vehicle including a center differential of the plurality of differentials assigned to two of the at least two axles having the driven wheels, the motor vehicle including at least one of a wheel-specific control system that is deactivatable for a driven case of the motor vehicle and for a braking action on the at least four wheels, a control system for the output torque of the internal combustion engine, and a control system for the output torque of the internal combustion engine, in the wheel-specific control system for the braking action when deactivated, the method comprising the steps of:measuring rpm quantities that represent rotational motions of the at least four wheels; generating a plurality of difference quantities as a function of the rpm quantities, the difference quantities representing at least one of an rpm and rotational speed differences at outputs of the differentials; comparing the difference quantities with specifiable threshold values; and adjusting the output torque of the internal combustion engine in accordance with a reduction if at least one of the specifiable threshold values is exceeded.
