Claims

[Scope of utility model registration request]

A suspension unit provided for each wheel that uses both main and auxiliary air spring chambers and auxiliary springs, a pair of communication pipes that connect the left and right air spring chambers of the front and rear suspension units, and A communication control valve interposed between the main and sub air spring chambers of each suspension unit, a reserve tank for storing compressed air, and piping connecting this reserve tank and the main air spring chamber of each suspension unit. An air supply control valve is provided for each suspended suspension unit, and an air supply control valve is interposed between the reserve tank and each air supply control valve, and the compressed air flow path can be selected into two large and small systems. an exhaust control valve provided for each suspension unit that is interposed in an exhaust pipe connecting the main air spring chamber of each suspension unit and the exhaust pipe;
a steering wheel angular velocity detection means for detecting the steering wheel angular velocity; a vehicle speed detection means for detecting the vehicle speed; and a steering wheel angular velocity detection means for detecting the steering wheel angular velocity; The flow path of the air supply flow path selection control valve is selected according to the control valve opening time given by the vehicle speed - steering wheel angular velocity map, and the air supply control valve and the exhaust control valve are controlled to open and close to control the vehicle body attitude. An electronically controlled suspension device comprising a controller.
