Electronic control suspension device

Abstract

Abstract PURPOSE:To prevent an amount of control from being short even at rapid acceleration and at rapid damping by variably setting an amount of suspension control corresponding to the magnitude of a longitudinal acceleration of a vehicle detected by an acceleration sensor. CONSTITUTION: An acceleration sensor 36 serving as a vehicle body sensor is adapted to detect changes in vehicle attitude such as pitching, rolling, and yawing on a vehicle spring. When a longitudinal acceleration detected by the sensor 36 is more than a prescribed value, an air supply solenoid valve 19, and solenoid valves 25, 26 are switched to for a control time T being controlled by a roll unit 34. Hereby, compressed air from a reservoir task 15a is fed to the main air spring chamber 3 of front suspension units FS1 and FS2 via the valves 19, 20, and 21, whereby a vehicle height at the front is lifted in response to an amount of attitude change in a noze dive.
