Vehicle control system

A vehicle control system applied to an object vehicle that includes an actuator for applying control force in an up-down direction to a suspension of an object wheel, the vehicle control system comprising:

• one or multiple processors that control the actuator to execute damping control for suppressing vibration in a sprung structure above the object wheel;
• and
• one or multiple storage devices that store a map indicating a correspondence relation between an up-down motion parameter related to up-down motion of a wheel, and a position, wherein
• the damping control includes
• a preview control that uses the up-down motion parameter that is obtained from the map, and
• a non-map-dependent control that uses the up-down motion parameter that is calculated based on a measurement result by a sensor that is installed in the object vehicle,
• a total gain is a sum of a first gain for the preview control and a second gain for the non-map-dependent control,
• an ideal gain is the total gain that minimizes the vibration of the sprung structure, and is set in advance, and
• the one or multiple processors are configured to set the first gain and the second gain such that the total gain does not exceed twice the ideal gain.
