ABSTRACT:
A suspension control system for an automotive vehicle employs a suspension system provided between a vehicle body and a suspension member rotatably supporting a road wheel, the suspension system incorporating means for varying suspension characteristics between at least a first mode with a softer suspension characteristic and a second mode with a harder suspension characteristic. A lateral acceleration sensor is provided for monitoring lateral acceleration exerted on the vehicle body to produce a lateral acceleration indicative signal. A control unit processes the lateral acceleration indicative signal in such a manner that the control unit detects initiation of vehicular rolling on the basis of the sum value for producing a first suspension control signal ordering the second mode and detects termination of vehicular rolling on the basis of magnitude of lateral acceleration for producing a second suspension control signal ordering the first mode.
