چکیده

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 dafür diskutiert. Der Analyseprozess, der Sicherheitsintegritätslevel des Systems und der Komponenten bestimmt, wird erläutert, gefolgt von der Spezifikation der Sicherheitsanforderungen und Überwachungsfunktionen. Zum Schluss werden einige modellbasierte Überwachungsfunktionen beschrieben, wie sie im technischen Sicherheitskonzept, speziell in der Verifikation der Eingangssignale des Active Front Steering der Nachfolgegeneration Anwendung finden sollen.

Integrated Active Front Steering and Semiactive Rear Differential Control in Rear Wheel Drive Vehicles

Abstract: Many vehicle control systems are based on the yaw rate error to help the driver during oversteer and understeer conditions. The control systems usually operate on brake pressures distributions such as ESP and/or on active front and rear steering control. Recently many papers are focused on the design of integrated global chassis control systems. The main contribution of this paper is ...

Optimal Roll Center Height of Front McPherson Suspension System for a Conceptual Class A Vehicle

In this paper, the effects of roll center height of McPherson suspension mechanism on dynamic behaviour of a vehicle are first studied, and then the optimum location of roll center of this suspension system is determined for a conceptual Class A vehicle. ADAMS/Car software was used for the analysis of vehicle dynamic behaviour in different positions of suspension roll center. Next, optimization...

Nonlinear 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...

Concept 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...

Experimental Verification of Reaction Torque Control Based on Driver Sensitivity to Active Front Steering

In today’s world, the effectiveness of electronic active control systems in stabilizing a vehicle’s motion has been recognized; thus, numerous active control systems have been developed to realize effective braking torque and traction control and have been incorporated in mass-produced vehicles. However, an effective active control system for steering is not yet available. Active front steering...
