Abstract
The invention provides a method and apparatus for controlling dampers in a suspension system of a vehicle body. A heave velocity of a vehicle body is derived from sensed dynamic variables of the vehicle body. A slew rate limit for a damping control command is derived in response to the heave velocity of the vehicle body. The damping control command for at least one dampers is generated in accordance with the slew rate limit. The limited damping control command is applied to the at least one damper
