Suspension control apparatus for a vehicle.

摘要

A suspension control apparatus for a vehicle having a plurality of suspension units S each disposed between a road wheel and the body of a vehicle for effectively and quickly correcting any deviation of the vehicle height from a normal height level immediately upon finishing of active suspension control operations. A suspension control unit 37 responds to signals from vehicle height sensors 34, roll sensor 39, speed sensor 38, steering sensor 40 and accelerator sensor 42. It determines priority for vehicle-height control and various active suspension control operations such as roll control, nose-dive and squat control, and pitching and bouncing control so that normal vehicle-height control is stopped or inhibited while active suspension control operations are being carried out, thereby preventing the traveling attitude of the vehicle from being made unstable. Also, a vehicle-height control determining time interval from the instant when active suspension control operations has been finished until the time when vehicle-height control is restarted is substantially reduced as compared with that required in the case when the vehicle is traveling in a normal attitude without any active suspension control operation, whereby any deviation of the vehicle height from a target height level can be quickly removed to make the actual vehicle height match with a target height level in a very short time immediately after the finishing of the active suspension control operations.
