Abstract
A tire load calculation section of a controller calculates tire load factors of the respective wheels. A target tire load-factor calculation section calculates a tire load factor average value (η) obtained by averaging the tire load factors (η) of the respective wheels as a target tire load factor. A target tire vertical-load calculation section calculates target tire vertical loads (Fzref) for the respective wheels so that the tire load factors of the respective wheels become equal to the tire load factor average value. A vertical-load control section and a suspension control section control thrusts of electromagnetic dampers for the respective wheels so as to achieve the target tire vertical loads.
