摘要： A pressure device control apparatus including a pressure source having a pump, and an accumulator connected to the pump and a pressure device, and a pressure detector for detecting the pressure in the accumulator; a normally-closed type solenoid valve interposed between the pressure device and the accumulator or a fluid tank; and a control unit having a drive control device for outputting a driving signal indicative of a command to operate the pump in response to a detection pressure detected in the pressure detector becoming equal to or less than a first predetermined pressure and a drive stopping signal indicative of a command for stopping the operation of the pump in response to the detection pressure becoming equal to or more than a second predetermined pressure which is higher than the first predetermined pressure. The control unit includes a first energizing unit for energizing the normally-closed type solenoid valve for a first predetermined time after the drive control device outputs the drive stopping signal, and a deciding unit for deciding that there is a problem in response to the detection pressure detected in the pressure detector becoming equal to or less than the first predetermined pressure after the energization of the normally-closed type solenoid valve by the first energizing unit is completed. This invention ensures that the diagnosis of the problem in the pressure device control apparatus can be reliably effected by the release of the pressure in the accumulator after the pressure increase thereof to a level equal to or more than the second predetermined pressure.

摘要： A pressure source (22) for a pressure device comprises a pump (P) for pumping a fluid from fluid tank (T), an accumulator (AC) connected to the pump (P) and a pressure device, a pressure detecting means (S1) for detecting the pressure in the accumulator (AC), and a controller (C1) for controlling the operation of the pump (P) in an ON-OFF manner on the basis of a result of detection by the pressure detecting means (S1). In this pressure source (22), the controller (C1) includes first and second drive signal generating circuits (251,252) each capable of indepedently generating a drive signal for determining the on-off operation of the pump (P), and a processing circuit (26) which has a calculating function therein and to which at least the pressure detecting means (S1) is connected. The processing circuit (26) is connected to the first drive signal generating circuit (251), and the pressure detecting means (S1) is connected to the second drive signal generating cirucit (252). This ensures that the control of the first drive signal generating circuit (251) can be carried out at any time by a calculation in the processing circuit (26), leading to an increased function. When the processing circuit (26) has a problem, the on-off control of the pump can be carried out by the second drive signal generating circuit (252).

摘要： PROBLEM TO BE SOLVED: To surely diagnose the earth failure of a switch circuit, wherein a switch is interposed between a power source and an earth part, by simple structure. SOLUTION: A power source Vcc and an earth part E4 are connected by a resistance R5 , a switch SW, and a resistance R6 ; and also the power source Vcc and the resistance R6 are connected by resistance R7 to discriminate electric potential at a point (c) by a discriminating means CPU. The electric potential at a point (c) becomes high electric potential when the switch SW is turned ON, and becomes low electric potential when the switch SW is turned OFF, and becomes zero electric potential when the point (d) is earthed to an earthed part E5 by failure. Consequently, earth failure can be discriminated at real time regardless of the ON/OFF condition of the switch SW.
