Abstract
A vehicle roll stabilizing system uses front and rear stabilizer assemblies (,) which each use a stabilizer bar (,) and a hydraulic ram (,) to resist vehicle roll. Selector valves (,) select pressure from a pump (,) or return hydraulic oil to a reservoir (,) according to 4 modes, two of which the selector valve is in an on and an off condition, respectively. A diverter valve (,) operates to control the pump pressure in proportion to lateral acceleration to provide an actuator effort which resists roll during vehicle cornering. This effort is provided up to a limit equivalent to a lateral acceleration of approximately 0.4 g after which roll is allowed to increase, either by keeping the pump pressure (and hence effort) constant or by increasing the pump pressure at a reduced rate.
