Abstract:
A method of controlling a suspension system for a motor vehicle, said suspension system including a shock absorber arranged between a vehicle body and a wheel of the motor vehicle and having a device for allowing a change in a damping-force characteristic, the method comprising the steps of:sensing a vertical behavior of the motor vehicle;sensing a roll angle of the motor vehicle during steering operation;sensing a roll rate of the vehicle during steering operation;carrying out a first control of the damping-force characteristic of the shock absorber in accordance with said vertical behavior as sensed;carrying out a first roll restraining control in place of said first control when said roll angle as sensed is equal to or greater than a predetermined threshold value; andcarrying out a second roll restraining control in place of said first control when said roll rate as sensed is equal to or greater than a predetermined threshold value,said second roll restraining control providing the damping-force characteristic of the shock absorber higher than that of said first roll restraining control.
