PURPOSE:To reduce power consumed by a pump by providing a pressure detector in a high pressure line leading to a power steering device, and actuating the hydraulic pressure control valve of an active suspension while constricting the valve in accordance with pressure drop in the high pressure line. CONSTITUTION:A hydraulic pump 1 is driven by an engine 2 and high pressure oil generated is fed to a high pressure line 3 and separated into a power steering device 9 and an active suspension device 10. In this case, the high pressure line 3 is provided with a pressure detector 6 and the output signal of the detector 6 is input to the active suspension controller 10. The signal of the pressure detector 6 is sent via an LPF 13 to a limiter circuit 14 and an output increase judging machine 15 along with the signal of a detector 10g for acceleration and the like and a hydraulic control valve 10c is controlled by final control operation input U2 obtained by limiting of control operation input U1 in accordance with lowering of the output Pm of the LPF 13. When the output Pm of the LPF 13 is lowered to below a reference value a signal requiring an increase in output is obtained for an engine controller 4. |
