Systemsicherheit des Active Front Steering (Active Front Steering - System Safety)
Active Front Steering ist ein elektronisch geregeltes Lenksystem für Kraftfahrzeuge, das situationsabhängig eine Überlagerung eines Winkels zum Lenkradwinkel erlaubt und somit eine Variation der Lenkübersetzung ermöglicht. Für ein solches System muss die funktionale Sicherheit gewährleistet sein. Ziele der funktionalen Sicherheit werden erläutert und messbare Kriterien und deren Nachweisbarkeit...
متن کاملConcept and Functionality of the Active Front Steering System
Active Front Steering (AFS) provides an electronically controlled superposition of an angle to the steering wheel angle. This additional degree of freedom enables a continuous and driving-situation dependent adaptation of the steering characteristics. Features like steering comfort, effort and steering dynamics are optimized and stabilizing steering interventions can be performed. After the suc...
متن کاملApplication Study of Active Front Steering with Integrated Feedback Control for Steering-by-Wire System
Combined with a linear two degrees of freedom vehicle model, a kind of new integrated feedback control strategy, which is on the basis of weighting factors of the realtime yaw rate and the lateral acceleration, is put forwards in this paper. An ideal variable steering ratio strategy is developed and the corresponding controller is also designed. By the computer-simulation technique, the double ...
متن کاملController design of a new active front steering system
An AFS (active front steering) on the basic of a C-EPS (column electric power steering) system was developed. Based on the mathematical model of essential components, the AFS controller was designed covering two units: an EPS actuator unit was used to reduce the steering torque requirement to the driver; an AFS actuator unit was used to compensate the steering angle for steering characteristics...
متن کاملNonlinear Controller Design for Active Front Steering System
Active Front Steering system (AFS) provides an electronically controlled superposition of an angle to the steering wheel angle. This additional degree of freedom enables a continuous and driving-situation dependent on adaptation of the steering characteristics. In an active steering system, there needs be no fixed relationship between the steering wheel and the angle of the road wheels. Not onl...
