An engine drag-torque control, particularly for motor vehicles, in which the
engine
torque is increased by an EDC augmenting torque when the driven wheels drop below
a slip threshold due to the braking action of the engine and exhibit a brake slip
which is too high. To improve the vehicle control during cornering on a roadway
having a low coefficient of friction, it is provided to increase the slip threshold
for the driven wheels to thereby set the drag-torque control to be more sensitive.
