This paper investigates an active front steering control strategy based on quantitative feedback theory (QFT). By incorporating
feedback from a yaw rate sensor into the active steering system, the control system improves the dynamic response of the vehicle.
The steering response of a vehicle generally depends upon uncertain quantities like mass, velocity, and road conditions. Thus,
QFT is used to design a controller with robust performance. A multi-degree-of-freedom nonlinear model is co-simulated here
by MATLAB Simulink and ADAMS/CAR. The performance of the control system is evaluated under various emergency maneuvers and
road conditions. The result shows that the designed robust control system has good control performance and can efficiently
improve handing qualities and stability characteristics. 相似文献

This paper describes the development of an optimal design process for a steering column system and supporting system. A design
guide is proposed at the initial concept stage of the development process to obtain sufficient stiffness of the steering system
while reducing the idle vibration sensitivity of the system. Case studies on resonance isolation are summarized, where vibration
modes among the systems are separated by applying a vibration mode map at the initial stage of the design process. This study
also provides design guidelines for an optimal dynamic damper system using a CAE (computer aided engineering) analysis. The
damper FE (finite element) model is added to the vehicle model to analyze the relation between the frequency and the sensitivity
of the steering column system. This analysis methodology makes it possible to achieve target performance in the early design
stage and reduction of damper tuning activity after the proto car test stage. Through the proposed steering column system
development process, a lightweight vehicle with high stiffness is possible prior to the proto build stage. Furthermore, the
improved process is expected to contribute to reducing the overall development period and the number of proto car tests necessary
to achieve the desired steering system performance. 相似文献
