PURPOSE:To prevent vehicle action from suddenly changing at the time of temporary power interruption or the like by delaying the supply of control oil pressure to a hydraulic actuator by the predetermined time, when a power supply is restored to a conduction condition from a temporary non-conduction condition. CONSTITUTION:A target control quantity, in which the optimum vehicle dynamic characteristic is obtained being based on predetermined input information, is determined by a means (b), while a control oil pressure for obtaining this target control quantity is supplied to a hydraulic actuator (a) from the means (b). While at the time of power supply off and/or in predetermined failure, a means (c) performs opening and closing so as to interrupt supply of the control oil pressure to the hydraulic actuator (a). Further a temporary non-conduction condition, in which the power supply is turned on from off within a short time, is detected in a means (d). When the power supply is restored to a conduction condition from the temporary non-conduction condition, an open command output to the means (c) is controlled so as to be delayed by the predetermined time by a means (e). In this way, a sudden change of vehicle action at the time of temporary interruption or the like is prevented. |
