Abstract
A suspension system S according to the present invention is configured to control actuators AFR, AFL, ARR, ARL by determining a pitch damping force FP and a roll damping force FR to cancel roll and pitch moments MP, MR of a body B, and determining target control forces FTFR, FTFL, FTRR, FTRL in consideration of the pitch damping force FP and the roll damping force FR. When the pitch damping force FP and the roll damping force FR are output to the actuators AFR, AFL, ARR, ARL, the actuators AFR, AFL, ARR, ARL can each generate a control force for cancelling a force acting on the body B not later but preliminarily.
Claims5
A suspension system comprising:
- four actuators interposed between a body of a vehicle and four front and rear, right and left wheels of the vehicle;
- and
- a controller for controlling the actuators, wherein
- the controller controls the actuators by
- determining a pitch damping force and a roll damping force to cancel roll and pitch moments of the body, respectively, on the basis of vertical displacements of the four front and back, right and left wheels in the vehicle, and
- determining a target control force for each of the actuators on the basis of the pitch damping force and the roll damping force.
