Abstract
A vehicle suspension control stores, for each direction of vehicle lateral acceleration, a first set of enhanced vehicle damping commands that provide enhanced damping in compression for the suspension dampers on the outside of a turn and in rebound on the inside of the turn and a second set of enhanced body damping commands that provide enhanced damping in compression and rebound on both sides of the vehicle. Responsive to a sensed vehicle lateral acceleration, the control applies the first set of enhanced damping commands to the suspension dampers if a sensed steering angle is in the same direction as the sensed lateral acceleration and applies the second set of enhanced body damping commands to the suspension dampers if the sensed steering angle is in the opposite direction as the sensed lateral acceleration. The control may derive a demand force command for each of the dampers from the determined relative velocities of the dampers and apply each of the demand force commands to its respective damper only when a comparison of the direction of the demand force command with the sensed relative velocity of the damper indicates that a force corresponding to the demand force command can be effectively exerted by the damper. The enhanced body damping commands are applied to the suspension dampers without regard for any application of the demand force command.
