    摘要: Provision of a power steering system capable of giving a driver no discomfort during high-speed travel. A controller calculates or stores a current instruction value I1 in accordance with a steering angle supplied from a steering angle sensor and a current instruction value I2 in accordance with a steering angular velocity; performs multiplication of the steering angle base current instruction value I1 and the steering angular velocity base current instruction value I2 by current instruction values I5, I6 set based on a vehicle speed, respectively; applies current instruction values I7, I8 in accordance with the vehicle speed serving as limit values to the corresponding steering angle base and steering angular velocity base current instruction values resulting from the multiplication; selects a larger value of the two current instruction values below the limit values; and determines the selected value as a solenoid current instruction value SI.

    摘要: In a power steering apparatus according to the present invention, a threshold ITH of a motor electric current for actuation of an oil pump is set at a lower level when a working oil has a high viscosity resistance at a low oil temperature, so that the oil pump can be actuated at an earlier stage. Conversely, when the working oil has a low viscosity resistance at a high oil temperature, the threshold ITH of the motor electric current for the actuation of the oil pump is set at a higher level because there is no need to actuate the oil pump at the earlier stage. Thus, the electric motor can be actuated without any problem even at an extremely low temperature, so that an entrapped feeling can promptly be mitigated.

    摘要: A motor is stopped (S14), if a steering angular speed V.theta. which is the time-related change rate of a steering angle is not greater than a stop threshold value Vb (YES in S10) and a motor electric current value Im is kept within a motor stop range .DELTA.I predetermined on the basis of a non-load electric current value for a predetermined time period (YES in S12, S13). The non-load electric current value is an electric current value observed at a steering torque of zero and, therefore, the motor stop range corresponds to a range where no steering assist force is required. That is, when the steering angular speed V.theta. and the steering torque are small, the steering assist is regarded unnecessary, and the motor is stopped.

    摘要: A flow regulator for a pump, particularly a vane pump, which regulates the fluid flow delivered to a consumer by the pump, and has a control piston acted on by the pressure built up by the pump, on the one hand, and, on the other, is acted upon by an initial force counteracting this pressure, and has a control edge, which interacts with the discharge bore, and a continuation, which penetrates an aperture, to form a delivery throttle, which is dependent on the piston path. The outside surface (31) of the continuation (25) of the control piston (5) has at least two regions (35, 37) with different outside diameters, separated from one another by a sharp-edged step (39).

    摘要: A hydraulic system for use in an automotive vehicle. A source of hydraulic pressure selectively operates in two modes. In one mode, it feeds a radiator cooling fan and a power steering system in parallel when a system pressure or flow exceeds a predetermined pressure rate. In another mode, it feeds the radiator cooling fan and the power steering system in series when the system pressure or flow is less than the predetermined pressure or flow.
