摘要：
A steering pressure control apparatus for a power-assisted steering system for a vehicle including a steering power cylinder to develop a steering assistance fluid pressure, comprising a detecting unit operative to detect a state in which the steering wheel is held in an angular position turned from the straight-ahead position thereof through an angle smaller than a predetermined value and to produce an output signal when the that predetermined state is detected; and a control unit responsive to the output signal from the detecting unit and operative to control the steering assistance fluid pressure to be developed in the steering power cylinder so that the steering assistance fluid pressure is lower or higher in the presence of the signal than in the absence of the signal.
