Suspension apparatus of automotive vehicle
First Claim
1. A suspension apparatus of an automotive vehicle having a liquid cylinder disposed between a member on a side of a vehicle body and a member on a side of each wheel and a flow rate control valve so disposed as to implement a supply or discharge of an operating liquid to or from a liquid pressure chamber of the liquid cylinder, comprising:
- a control means for generating a control signal to the flow rate control valve so as to make the vehicle body in a reversely rolling state in a predetermined running region;
a vehicle-behavior detecting means for detecting automotive vehicle body movement; and
a determination means for determining the movement of the automotive vehicle in accordance with a signal detected by and generated by said vehicle behavior detecting means, wherein the determination means suspends control by the control means to reverse roll control the movement of the vehicle body by making the vehicle body roll in a reverse way when the movement of the automotive vehicle has been determined by said determining means as changing frequently.

Abstract
A suspension apparatus of an automotive vehicle having a liquid cylinder disposed between a member on the side of a vehicle body and a member on the side of each wheel and a flow rate control valve so disposed as to implement a supply or discharge of an operating liquid to or from a liquid pressure chamber of the liquid cylinder is so designed as to implement reverse roll control for reversing rolling the vehicle body when the vehicle is running in a predetermined running region. When the behavior of the vehicle is changing frequently, for example, when the vehicle is running along a zig-zag course, namely, when the direction of transverse acceleration acting upon the vehicle body changes frequently, the reverse roll control is inhibited.
