Traction-slip control method with theoretical transversal acceleration and control circuit for carrying out such a traction-slip control method

A control circuit for controlling the driving stability of a vehicle, wherein defining input quantities for fixing a course are sensed and processed so that traction slip control can be performed by influencing a transmission of engine torques to individual wheels, comprising:

• a control circuit having a means for determining and/or storing a reference transverse acceleration for a cornering maneuver to be expected and a comparator;
• wherein the comparator compares the reference transverse acceleration (ay-ref) with a determined actual transverse acceleration, and it is determined whether the amount of the difference exceeds a limit value;
• and
• wherein in the case that the amount of the difference exceeds the limit value, the slip control is modified so that a higher torque can be achieved at least on two wheels than in the case that the amount of the difference does not exceed the limit value.

A traction slip control method for an automotive vehicle wherein a traction slip control phase for a respective drive wheel is activated by way of a control strategy when the traction slip of said wheel exceeds a predeterminable slip threshold value comprising the steps of:

• determining a reference transverse acceleration for a cornering maneuver to be expected;
• determining an actual transverse acceleration;
• calculating a difference between the reference transverse acceleration (ay-ref) and the actual transverse acceleration (ay-ist);
• and
• determining whether the amount of the difference exceeds a limit value, and wherein in the case that the amount of the difference exceeds the limit value, modifying the control strategy so that a higher torque can be achieved on all driven wheels than in the case that the amount of the difference does not exceed the limit value.
