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 a connection between this reserve tank and the main air spring chamber of each suspension unit. An air supply control valve provided for each suspension unit installed in the piping, and an air supply control valve interposed between the reserve tank and each air supply control valve to select two large and small compressed air flow paths. a control valve for selecting an air supply flow path, an exhaust control valve provided for each suspension unit installed in the exhaust pipe connecting the main air spring chamber of each suspension unit and the exhaust pipe, and a handle. A steering wheel angular velocity detection means for detecting angular velocity, a vehicle height detection means for detecting the vehicle height of the vehicle body, and a vehicle height sensor position map or a vehicle speed-steering wheel angular velocity map based on the magnitude of the steering wheel angular velocity detected by the above-mentioned steering wheel angular velocity detection means. 1. An electronically controlled suspension device comprising: a controller that controls the opening and closing of the air supply control valve and the exhaust control valve by selecting the control valve opening time given by either one of the control valves, and controls the vehicle body attitude.
