A system (1) for controlling and/or adjusting a steering system of a vehicle (2), mechanically coupled to the wheels (8) and including an actuator (25) for applying a force or a torque to the steering system. A force or torque can be superimposed on a force or torque originating from the wheels (8). The system (1) includes at least one detection unit (4) disposed on the vehicle (2) and configured for anticipatorily detecting at least one surface condition (20) of a surface section located ahead of the vehicle (2) in the direction of vehicle travel and subsequently driven on by the vehicle (2). The system including a data processing unit (6) disposed on the vehicle (2) and connected to and communicating with the detection unit (4). The data processing unit (6) configured for generating control signals for controlling an actuator (25) of the steering system based on the detected surface condition (20).
