US-OS characteristic control system for a vehicle responding to turning state quantity and the changing rate thereof
First Claim
1. A control system for controlling the US-OS characteristic of a vehicle having suspension for the front and the rear vehicle wheels, comprising:
- a means for changing the US-OS characteristic of the vehicle;
a means for detecting a turning state quantity;
a means for determining the changing rate of a turning state quantity;
a control means which, in response to the turning state quantity detected by said detecting means and the changing rate of the turning state quantity determined by said determining means, controls said US-OS characteristic changing means so that the higher the changing rate of the turning state quantity is, the more the US-OS characteristic may be shifted toward higher over-steer, and for the same changing rate the higher the turning state quantity is, the more the US-OS characteristic may be shifted toward higher under-steer.

Abstract
In a system for controlling the US-OS characteristic of a vehicle having front and rear suspensions, a device for changing the US-OS characteristic is provided which is adapted to alter the roll stiffness distribution between the front and the rear suspensions. A turning state quantity is detected and the changing rate of a turning state quantity is determined. A control device is further provided which is adapted to respond to the turning state quantity and the changing rate of the turning state quantity, and to control the US-OS characteristic changing device so that the higher the changing rate of the turning state quantity is, the more the US-OS characteristic may be shifted toward higher over-steer, and for the same changing rate the higher the turning state quantity is, the more the US-OS characteristic may be shifted toward higher under-steer.
