Abstract

"Yawing center" may be considered significant information for the driver to control vehicle steering performance.

This paper introduces the concept of "yawing center" of a vehicle in yawing motion, with the following factors analyzed by computer simulation with two-degreesof freedom:

How "yawing center" of two-wheel steering car varies while running.
How it is improved by adopting four-wheel steerings ystem.

The results indicate that it is possible to control the position of "yawing center" by using a four-wheel steering system, which improves vehicle response to steering input and reduces cornering kinetic energy.
