The Influence of Different Vehicle Parameters on Steering Controllability and Stability
Published January 01, 1983 by Institution of Mechanical Engineers in United Kingdom
The research in the field of vehicle handling and stability during the past ten years focused to a great extent on the interaction between driver and vehicle in order to improve the performance level of the driver/vehicle system with respect to steering comfort and safety.
The aim of this paper is to describe the influence of different vehicle parameters such as vehicle weight, weight distribution, steering compliance, wheel suspension geometry, tyre characteristics, etc. on steering controllability and stability in the entire range of lateral accelerations.
The study has been performed with the help of an uncomplicated mathematical model, which has been very useful during the development of vehicle handling measuring methods in the Volvo Car Corp.
The results are described using steering control and stability characteristics based on the above-mentioned measuring methods. The investigation indicates, among others, that steering controllability and stability of the driver/vehicle system can be improved considerably, especially in the range of high lateral accelerations.
