Patent attributes
A suspension system for a vehicle, including: four displacement force generators each having an electromagnetic motor and configured to generate, based on a motor force generated by the motor, a displacement force forcing sprung and unsprung portions of the vehicle toward or away from each other; and a controller configured to control the displacement force generated by controlling operation of the motor is disclosed. The controller includes a target-value determining portion configured to determine a target value of a displacement-force-relating amount of each of the four displacement force generators, and a target-value reducing portion configured to reduce the target value of the displacement-force-relating amount of a subjected device as one of the four displacement force generators, in accordance with a certain rule. The target-value reducing portion is configured to reduce the target value of the displacement-force-relating amount of each of at least one of non-subjected devices as the other three of the four displacement force generators, in accordance with the certain rule, when reducing the target value of the displacement-force-relating amount of the subjected device in accordance with the certain rule.
