Claims

[Scope of utility model registration request]

A suspension unit provided for each wheel using a combination of main and sub air spring chambers and auxiliary springs, a pair of connecting pipes connecting the left and right main air spring chambers of the front and rear wheel suspension units, and this connecting pipe. A communication control valve interposed between the main air spring chambers of each suspension unit, a reserve tank for storing compressed air, and an air supply valve that connects this reserve tank and the main air spring chamber of the suspension unit. An air supply control valve provided for each suspension unit installed in the piping, and each suspension unit installed in the exhaust piping connecting the main air spring chamber of the above-mentioned suspension unit and the exhaust pipe. control provided by an exhaust control valve provided in the exhaust control valve, a vehicle speed detecting means for detecting the vehicle speed, and either a vehicle speed-steering wheel angle map or a vehicle speed-steering wheel angular velocity map depending on the magnitude of the vehicle speed detected by the vehicle speed detecting means. An electronically controlled suspension device comprising: a controller that selects a valve opening time and controls the opening and closing of the air supply control valve and the exhaust control valve to control vehicle body posture.
