PROBLEM TO BE SOLVED: To enable improving both riding comfort and feeling, and stability when a vehicle turns.SOLUTION: A controller 18 operates lateral acceleration of a vehicle body side in estimation based on detection signals from a vehicle speed sensor 15 and a steering angle sensor 16, and obtains the lateral jerk. Warp rigidity of a target that is the rotating rigidity of a diagonal direction of the vehicle body is obtained according to a lateral jerk of the vehicle body. For instance, when determining that the vehicle turns right, an opening command is output from the controller 18 to a supply and drainage valve 13A of a left front wheel side and a supply and drainage valve 13D of a right rear wheel. As a result, an air spring 11A of the left front wheel side and an air spring 11D of the right rear wheel are made to communicate, and air is circulated between the air spring 11A of the left front wheel side and the air spring 11D of the right rear wheel side. As a result, a vehicle attitude of a front down roll can be achieved at a turning operation of the vehicle. |
