Abstract
When a single shock due to a bump or dip in a road surface is detected at the front wheel of a vehicle running on the road, the characteristic of the air suspensions is immediately altered to improve comfort of ride thereof. For that purpose, a distance between the body of the vehicle and the front wheel is detected and when the distance exceeds a predetermined value, the suspension characteristic is altered to a softer state by communicating the air chambers of the front and the rear air suspensions. Further, the pressures of the air chambers are detected and, in case the pressure difference is greater than predetermined value, the communicating operation is prohibited in order to prevent an abrupt change of the vehicle posture.
