摘要： A controllable valve assembly (18) applicable in Magnetorheological (MR) fluid devices (20), such as MR mounts and MR dampers. The valve assembly (18) includes a valve body (32) having a magnetic circuit (40) contained therein which carries magnetic flux .PHI., a controllable passageway (42) within the magnetic circuit (40), a MR (magnetically controlled) fluid (44) including soft-magnetic particles in a liquid carrier contained in the controllable passageway (42), a magnetic flux generator, such as a wound wire coil (46), generating magnetic flux .PHI. which is directed through the MR fluid (44) in the controllable passageway (42) thereby generating "rheology" changes causing restriction in flow of MR fluid (44) therethrough. In one aspect, a one-way check valve (34) is operative with a passive passageway (36) which is arranged in parallel relationship to the controllable passageway (42) provides "asymmetric" damping across the controllable valve (18) creating higher pressure differentials in a first direction and a lower in a second direction without "rapidly switching" the current to the coil (46). In another aspect, "asymmetric" damping is provided by a "changeable gap" formed by a moveable wall portion of the controllable passageway (42). In a third aspect, a first controllable passageway provides controllable flow in a first direction and a second controllable passageway provides controllable flow in a second direction, thereby provide "asymmetry." In a fourth aspect, "asymmetry" is provides by a "variable magnetic short" which changes magnetic circuit reluctance dependent on flow direction.

摘要： An Adaptive Off-state (AO) control method (55) for use in conjunction with a suspension system (10) including a controllable damper (22) interconnecting relatively moveable members (12, 14) to reduce the transmission of vibrational forces therebetween. Such suspension systems (10) are switchable between alternative on- and an off-state in accordance with a primary control method (53) and/or a secondary override control method (59). Sensors (48, 52) monitor the parameters of the suspension system (10), such as the displacement, velocity, and acceleration of the moveable members (12, 14). Damper command signals (107) are provided to the damper (22) in the on-state (116) to adjust the damping characteristics thereof. In the off-state, the damping signal in conventional systems is approximately zero or a constant relatively low magnitude. According to the present adaptive off-state control method (55), the off-state damping signal (109) to the controllable damper (22) is modulated over time to make the off-state damping a function of the system inputs. In a preferred embodiment, the modulation is a function of the real time or time-averaged input disturbances to the system (10). In an alternative embodiment, the modulation is derived from a user switch (57) that imparts a user variable Off-State Gain (OSG) to the off-state damping signal (109) based on operator perceived ride characteristics.
