PURPOSE:To make improvements in a feeling of driving comfortableness and drivability, by judging the occurrence of rolling on the basis of road surface states at both sides, while controlling a degree of roll rigidity, and constituting a setting value for judgment so as to be changed with the control signal. CONSTITUTION:Each of detecting signals RL and RR out of road state detector 1L and 1R is inputted into a differential value output circuit 3 via each of processing circuits 2L and 2R and outputted to a signal processing circuit 4 as signal differences at both sides. This signal processing circuit 4 individually selects and extracts an unspringing resonance component and a springing resonance component and outputs each of signals VA and VB to a judging circuit 5. A roll judging circuit 5 compares these input signals VA and VB with the setting value and outputs each of spring constant command signal CS1-CS4 commensurate to the preset spring constant to an air pressure regulator 6, controlling each of variable rate springs 11a-11b, simultaneously changes the setting value via a voltage setting circuit 7 for judgment. Thus, a feeling of driving comfortableness is improved. |
