Abstract: A delay which may take the form of a hydraulic flow restriction (either fixed or variable with a given parameter such as vehicle speed) or a suitable electronic delay circuit, is interposed between a device which outputs a signal indicative of the front wheels being steered and a device which is operatively connected with the rear wheels and which varies the orientation of the rear wheels in a manner to "steer" same in response to the signal to control the yawing of the vehicle.

Abstract: To control the compliance steering of the rear wheels of a vehicle during cornering or the like, a link member of the rear suspension arrangements supporting each of the rear road wheels, is provided with a servo mechansim which can vary the length thereof in a manner which tends to steer the rear wheel associated therewith in the same direction as the front wheels are turned to produce the cornering.

Abstract: The pressure outputs of a power steering control valve are fed either to hydraulic cylinders (or servos) or to chambered elastomeric insulator units to, in the case of the rear wheels, produce a bias which opposes a side force produced during cornering to prevent the rear wheels from undergoing "compliance steering", while in the case of front wheels, induce same to turn through an angle slightly greater than intended by the driver to either prevent compliance steering or increase same to improve vehicle handling when cornering respectively .
