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 suspension for front and rear wheels, a pair of communication pipes connecting the left and right air spring chambers of the John unit, and this communication pipe. A communication control valve is installed between the main and auxiliary air spring chambers of each suspension unit in the road, and a reserve tank that stores compressed air is connected to 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. an exhaust control valve provided for each suspension unit, which 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, an internal pressure weft means for detecting the internal pressure of each of the main air spring chamber and the reserve tank, and a steering wheel angular velocity detection means based on the magnitude of the steering wheel angular velocity detected by the steering wheel angular velocity detection means. The control valve opening time given by the angular velocity map is corrected based on the internal pressures of the main air spring chamber and the reserve tank detected by the internal pressure detection means using the correction coefficient given by the main tank internal pressure-reserve tank internal pressure map. An electronically controlled suspension device comprising: a controller that controls opening and closing of the air supply control valve and the exhaust control valve according to the control valve opening time to control vehicle body posture.
