The Active Front Steering (AFS) system has been described, from a plain functional point of view, though (i.e. a electronically controlled superposition of an angle to the hand steering wheel angle that is prescribed by the driver). The need for installing model based safety functions, additionally to the basis sensor diagnostics and range and gradient checks, has been motivated and some of the application dependent safety functions have been described, in particular the pinion angle plausibility check and the monitoring of the kinematic relation between the three angles, important for AFS. This list is far from being complete. A function, that can be directly experienced by the driver has been described as well: the (speed and pinion angle) variable steering ratio. All descriptions have been accompanied by measurements from AFS vehicles. Another function that can be experienced by the driver is the so-called steering lead, that essentially enhances the vehicle reaction during quick steering maneuvers. This function will be described in future works, also some more details on particular model based safety functions. Future work with respect to the safety functions will focus on more advanced monitoring strategies such as observer based approaches.
