A gear ratio of an automatic transmission is set by a fuzzy logic circuit which evaluates a braking torque desired by a motor vehicle driver and which carries out a change in the transmission gear ratio in order to support the braking torque of a brake system. After changing the transmission gear ratio, the braking torque desired by the driver is again evaluated and, in accordance with the evaluation result, the transmission gear ratio is, if appropriate, again adjusted in view of the desired braking torque. A drive train control system is also provided.
