摘要： A vehicle suspension system control unit (40) is arranged to determine from a lateral accelerometer (42) and vehicle speed sensor (44) when the vehicle is executing a series of opposite turns in a slalom type manner which are likely to cause a build-up of body roll. In this situation the roll control system is modified from a regime in which some body roll is allowed, to a regime in which body roll is substantially prevented thereby to prevent the build up of body roll during slalom type manoeuvres.

摘要： An active vehicle roll control system is disclosed in which a roll bar (22) has two halves (22a, 22b) which can be locked together to allow the system to operate passively. A sensing system based on a lateral accelerometer and vehicle speed sensor is arranged to detect when the vehicle is on a side slope and to put the roll control system into the passive mode.

摘要： In an active roll control system for a vehicle, anti-roll bars (26, 30) are provided with actuators (28, 32) which can provide a torque in the anti-roll bars to control vehicle body roll. Under certain cornering conditions when the vehicle is liable to over-steer, the pressure supply to the actuators is pulsed so that the front wheels of the vehicle tend to break away more easily, thereby reducing over-steer.

摘要： An active vehicle roll control system is disclosed in which a roll bar (22) has two halves (22a, 22b) which can be rotated relative to each other by a control unit (26) in order to actively control vehicle roll. The control unit (26) receives signals from lateral accelerometers (29, 30). In order to determine accurately when the vehicle is experiencing zero lateral acceleration, the control unit (26) averages the signal from each accelerometer (29, 30) continuously and uses the average signal as an indication of the straight ahead position. The averaging algorithm defines a window of low lateral accelerations to be used, and a gain to be applied to the acceleration signals, each of which is speed dependent so that the averaging process is not affected by abnormal vehicle movements.

摘要： A vehicle roll stabilising system uses front and rear stabiliser assemblies (23, 34) which each use a stabiliser bar (24) and a hydraulic ram (33, 35) to resist vehicle roll. Selector valves (43, 44) select pressure from a pump (36) or return hydraulic oil to a reservoir (37) according to mode. A diverter valve (73) 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 0.4g 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.
