を特徴とする電子制御サスペンシヨン装置。 A suspension unit is provided for each wheel and has a fluid spring chamber, and when a roll occurs, fluid is supplied to the fluid spring chamber of the suspension unit on the compression side, and fluid is supplied from the fluid spring chamber of the suspension unit on the floating side. A suspension device that suppresses vehicle body roll by discharging damping force includes a damping force switching device that switches the damping force of each suspension unit between hard and soft, a vehicle speed detection means that detects vehicle speed, and a steering wheel angular velocity. A steering wheel angular velocity detection means, a vehicle speed-steering wheel angular velocity map having a region for specifying the damping force of a front or rear only suspension unit as hard or soft depending on the vehicle speed and the steering wheel angular velocity, and a vehicle speed detected by the vehicle speed detection means. When the steering wheel angular velocity detected by the steering wheel angular velocity detecting means is in a region where only the rear suspension is made hard, the rear suspension unit damping force switching device switches the damping force of the rear suspension unit to hard. An electronically controlled suspension device characterized by:
