VEHICLE SUSPENSION CONTROL WITH VEHICLE HANDLING ENHANCEMENT HAVING RELATIVE VELOCITY DEPENDENT ADJUSTMENT

A vehicle suspension control derives demand force commands from relative velocities of the suspension dampers at the corners of the vehicle and applies the demand force commands only when a force corresponding to the demand force command can be effectively exerted by the damper. The control is also responsive to a sensed vehicle handling event to derive a body control enhancement damping commands for selected suspension dampers and apply the body control enhancement damping commands without regard for the direction of demand force for the suspension dampers. Each body control enhancement damping command is derived from one or more measured vehicle dynamic variables associated with the sensed vehicle handling event and modified in magnitude in response to the direction and/or magnitude of the sensed relative velocity of damper to which the body control enhancement damping command is to be applied.
