A high-pressure fluid shutoff valve and an optional electrically or manually operated valve are additionally provided as means to ensure disconnection of the high pressure source in the event of a failure. Displacement stroke position and pressure differentials across the pump/motor are continually monitored. On detection of various modes of failure or irregularity in control of displacement, actions are taken including any of: the high pressure and low pressure accumulators are shut off automatically or manually, a check valve between the high and low pressure ports of the pump/motor is activated, and a small amount of pressurized fluid is released from the high pressure circuit to depressurize the captive fluid. Safe startup and shutdown procedures are also specified. The system provides for safe operation of a hydraulic hybrid vehicle that includes an engine pump and drive motor, at least one of which operates over-center. The system optionally provides a displacement control valve that is controlled by feedback from an actuator or displacement position sensor and that on loss of electric power to the displacement control valve will cause the controlled pump/motor to stroke to a zero displacement position. | ||||||

| In a method for controlling a valve system controlling an actuator, the first direction of motion of the actuator is controlled solely by the first and the second valve series; or, its second direction of motion is controlled solely by the third and the fourth valve series; and an error caused by a fault situation in the control of the actuator is compensated for by using, for the control of the first direction of motion, also the third valve series, the fourth valve series, or both of them; or, an error in the control of the actuator caused by a fault situation is compensated for by using, for the control of the second direction of motion, also the first valve series, the second valve series, or both of them. In the method, for searching for faults in the valve system controlling the actuator, the pressure of the inlet port of the valve system, the pressure of the first working port, and the pressure of the outlet port are determined; one or more valves of the first valve series and one or more valves of the second valve series are opened; the measured pressure of the first working port is compared with a situation corresponding to a system operating correctly; and on the basis of the comparison it is concluded whether the single valve is faulty or not. | ||||||
