ことを特徴とする電子制御サスペンシヨン装置。 In an electronically controlled suspension system equipped with an attitude control function that reduces roll displacement of the vehicle body by individually adjusting the fluid pressure in the fluid spring chambers provided in each left and right suspension unit, damping is provided in each suspension unit. A damping force switching function that switches between hard and soft forces, an actuator that controls the damping force switching function, a G sensor that detects lateral acceleration acting on the vehicle body, and a roll control function using the above attitude control function. The vehicle is characterized by comprising control means for operating the actuator to hard control the damping force switching function of each of the suspension units when an acceleration equal to or higher than a preset acceleration is detected by the G sensor. Electronically controlled suspension device.
