1 What -- Amendment 1986.4.5 The name of the invention is amended as follows. ■Name of the invention The scope of the electronically controlled suspension device utility model registration claim and the brief description of the drawings are amended as follows. Scope of Claim for Utility Model Registration A suspension unit provided for each wheel and each having a fluid spring chamber, a fluid supply means capable of supplying fluid to each spring of each suspension unit through a supply on-off valve, and a suspension. A fluid discharge means capable of discharging fluid from each fluid spring of the unit through a discharge on-off valve, and a fluid spring chamber of each left and right suspension unit are communicated between the front wheels and the rear wheels through communication control valves. m mark υ The fluid spring chamber of the front wheels and the rear wheels are mutually moved, and when roll displacement of the vehicle body is detected by the roll displacement detection means, the communication control valve of the communication means is closed, and the roll direction of the vehicle body is By opening the supply on-off valve of the fluid splash chamber on the compression side of each suspension unit for a set time, a set amount of fluid is supplied to the fluid spring, and the discharge phase opening valve of the spring on the extension side is set. By opening the fluid spring chamber at the same time and discharging a set amount of fluid from the fluid spring chamber, it suppresses the roll displacement of the vehicle body and prevents it from rolling several times! When the handle angle detected by the handle angle detection means becomes less than the set value, the communication control valves of the communication means are turned on and off. In the suspension device equipped with displacement suppression control means, acceleration detection means 31μ detects lateral acceleration acting on the vehicle body.
The roll suppression control means detects roll displacement of the vehicle body by the roll displacement detection means and performs control to suppress the roll displacement, and then the acceleration detected by the acceleration detection means becomes equal to or less than a set value. ``Time'' 2 above, ゛hand
An electronically controlled suspension device, characterized in that it is configured to open a continuous suspension control.

Claims (1)

[Scope of utility model registration request] A suspension unit provided for each wheel that uses a lateral acceleration sensor that detects lateral acceleration, main and auxiliary air spring chambers, and auxiliary springs, and a pair that connects the left and right main air spring chambers of the front and rear wheel suspension units. a connecting pipe, a communication control valve interposed between the main air spring chambers of each suspension unit in this connecting pipe, a reserve tank for storing compressed air, and a main air supply between this reserve tank and the main air spring chamber of each suspension unit. An air supply control valve provided for each suspension unit is installed in the air supply pipe connecting the spring chamber, and an air supply control valve is installed in the exhaust pipe connecting the main air spring chamber of each suspension unit and the exhaust pipe. After controlling the attitude by controlling the opening and closing of the exhaust riverside control valve provided for each suspension unit installed, the communication control valve, the air supply control valve, and the exhaust control valve, the lateral acceleration is detected by the lateral acceleration sensor. An electronically controlled suspension device comprising: a controller that opens the communication control valve and cancels attitude control when it is detected that the lateral acceleration is below a reference lateral acceleration.
