The tilt control system includes a stabilizer bar adjustable by a hydraulic actuator which is movable in first and second opposing directions for adjusting vehicle body roll resistance provided by the stabilizer bar, and having a pressure control valve for controlling hydraulic pressure to the actuators. The method includes the following steps: a) obtaining a lateral acceleration magnitude signal; b) comparing the lateral acceleration magnitude signal to a first lateral acceleration threshold; c) enabling the active tilt control system for the vehicle when the lateral acceleration magnitude signal exceeds the first lateral acceleration threshold; d) disabling the active tilt control system for the vehicle when the lateral acceleration magnitude signal is less than the first lateral acceleration threshold; e) comparing the lateral acceleration magnitude signal to a third lateral acceleration threshold; and f) resetting the active tilt control system for the vehicle when the lateral acceleration magnitude signal is less than the third lateral acceleration threshold continuously for at least a predetermined period of time.Field of SearchAttitude change suppressive control (e.g., antiroll or antipitch)Indication or control of braking, acceleration, or deceleration Antiskid, antilock, or brake slip control VEHICLE CONTROL, GUIDANCE, OPERATION, OR INDICATION Antiroll or antisway SUSPENSION MODIFICATION ENACTED DURING TRAVEL (I.E., ACTIVE SUSPENSION CONTROL) Of lateral vehicle attitude (e.g., antiroll, antisway) Including condition or parameter adjustment occurring at longitudinally spaced vehicle axles Controlling lateral vehicle attitude (e.g., antiroll, antisway) Lateral and longitudinal vehicle attitude control (e.g., combinations of antidive, antipitch, antiroll, antisquat, antisway, antiyaw, riding, or suspension height) Lateral vehicle attitude | |
