PURPOSE:To make it possible to effect anti-roll control at substantially whole steering speeds, by controlling to maintain a damping force and a spring constant high in the case that difference in load pressures to right and left wheels exceeds a set value during turning of a vehicle for a time beyond a set time of a timer. CONSTITUTION:Output phi and v from a steering speed sensor 1 and a vehicle speed sensor 2 are compared with set values phi0 and v0 by respective comparators 3 and 4. If phi>phi0 and v>v0, a driving circuit 7 is operated by OR gates 6 and 21 to select a damping force selecting actuators 8 to a hard position and also select a spring constant selecting actuator 9 to a high spring constant position. The operation of the driving circuit 7 is continued for a set time of a timer 11. Further, difference DELTAP0 in load pressure to right and left wheels is detected by a pressure differential sensor 12. If an output from the sensor 12 is higher than a reference value DELTAP0, he driving circuit 7 continues to be operated by an output from an AND gate 17 even after the set time of the timer is elapsed. |
