A suspension device includes: a damping device that damps a force generated between a vehicle body and a wheel of a vehicle; a determination unit that determines whether the vehicle is jumping, using an acceleration of the vehicle in a front-rear direction, an acceleration of the vehicle in a left-right direction, and an acceleration of the vehicle in a vertical direction; and a damping force control unit that increases a damping force of the damping device so as to be greater than the damping force generated when the determination unit does not determine that the vehicle is jumping, when the determination unit determines that the vehicle is jumping.

A shock damper is disposed between a vehicle body side and a wheel side. A suspension control device calculates a damping force of the shock damper on the basis of vehicle height information and controls the damping force. A steering system includes an electric motor and a steering control device that controls the electric motor, and assists steering effort of the driver through the electric motor. The suspension control device calculates the vibration generated in a steering on the basis of a detected value of a vehicle height sensor and creates a signal for generating steering torque that reduces the generated vibration. The suspension control device outputs the created signal to the steering control device. Steering torque for cancelling steering vibration is accordingly outputted from the electric motor of the steering system.

The present invention obtains a controller capable of suppressing worsening of comfort of an occupant in a vehicle when compared to the background art.

The controller according to the present invention is a controller that is mounted to the vehicle and outputs a command signal corresponding to a damping coefficient of a shock absorber to an actuator that adjusts the damping coefficient of the shock absorber of a damping force adjustment type. In the case where, in the vehicle, a portion on a wheel side with the shock absorber being a reference is set as an unsprung portion, where a state where a frequency of the unsprung portion is higher than a prescribed frequency is set as a first frequency state, and where a state where the frequency of the unsprung portion is lower than the prescribed frequency is set as a second frequency state, the controller is configured to output, to the actuator, such a command signal that reduces the damping coefficient of the shock absorber to be smaller than the damping coefficient of the shock absorber in the second frequency state when a state becomes the first frequency state.

A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.
