Stability problems of vehicles, especially commercial vehicles, get more and more attention with the increasing traffic load of the roads. The development of infrastructure can not follow the demands for the increasing traffic and it result in increasing number of accidents. The society can not accept this situation and it raises higher and higher demand on the active safety of the vehicles. This demand resulted that the brake system based drive stability systems are available today and in some cases are obligatory. If the driver demanded vehicle motion (which is calculated on the basis of a reference vehicle model) differs from the measured vehicle motion, the system applies a moment using the brakes to force the vehicle to move on the desired path. However the brake is activated without the direct command from the driver, the system can not be considered as an autonomous driver assistant system, because it just supports the driver to reach his demand. The driver is apart of the control hop completely. The target of the paper is to extend the drive stability system with active steering intervention. The new generation steering systems with the help of a superimposing gear can manipulate the steering angle, and so they can manipulate the acting forces of the tire contact point. So the new generation of the ESP requires the appropriate steering system. As apart of the current development the adequacy of the model is checked by a validation process with a continuous feedback.
