PURPOSE:To attain the anti-skid control effectively and with high responsiveness for the dampling control of an automobile, by controlling the impression of high voltage to a piezo-element which is selected in accordance with the contents of a control command. CONSTITUTION:An actuator group 11 consists of plural piezo-elements forming plural plural control valves. In this case, the sensor group 13 detects the revolving speeds, the damping force, the ground speeds, etc. of the wheels. These detection signals are supplied to a control circuit 14. The circuit 14 monitors the state of the control which affects each wheel according to said detection signals. When a lock state is produced, the circuit 14 gives a command to a piezo-element driving circuit 12 to reduce the damping force applied to the locked wheel. Then the power supply voltage supplied to each actuator of the group 11 from a high voltage source 15 is controlled. |
