Abstract
To evaluate a possible driver behaviour for a car and a car-trailer combination a 2- and a 3-level driver are compared. The 3rd level is based on the sliding control approach and moreover takes into account the intentions of a driver to reach the road trajectory with a smooth transition. The simulations are made with a complex car and trailer model while the basics of the control formulations use linearized models. With the results it was possible to show that an increase of the steering activity due to the 3rd level improves the quality of the path correction but leads to partially stronger dynamics of the vehicle.
