ABSTRACT:
A control method for semi-active damper (32) which oscillates in real time (at the frequency of the moving member (22) motion or higher) between a high-damping On state and a low-damping Off state wherein the On and Off damping states are selected by the driver via a driver selectable switch (60) and overridden when the absolute velocity differential across the suspended body exceeds a threshold value and the signs are opposite. Damping bands can be set to a luxury, touring, or sport mode via the driver selectable switch (60). This system provides driver selectable ride feel and yet controls excessive roll and pitch due to vehicle maneuvers, braking, and acceleration by overriding the driver selectable setting whenever the absolute velocity differential threshold setting is exceeded and the directional signs are different. When the threshold is exceeded and the signs are opposed, the null band is adjusted to a narrower setting to initiate control of the damper. This allows the null band to be set wider for normal driving, providing better isolation.
