Abstract
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.
