    • A method and apparatus for correcting the zero pressure value of a hydraulic power steering pressure sensor. A power steering pressure PK is detected through pressure sensors 9 and 10 of a power steering cylinder 1 after an engine 14 stops running. The number of detections D [PK] of the power steering pressure PK is added up, provided that the power steering pressure PK remains unchanged for a predetermined time period, and then after a predetermined time period passes after the engine has stopped running, the power steering pressure PK, at which the number of detections D [PK] reaches a maximum value, is adopted as the zero pressure value of the pressure sensors. This makes it possible to accurately correct the zero pressure value of the pressure sensors in the hydraulic power steering unit.
    • 一种用于校正液压动力转向压力传感器的零压力值的方法和装置。 后发动机运行14点停止通过压力传感器9和一动力转向缸1的10时,检测到动力转向压力PK。 提供的动力转向压力PK被添加了的检测D [PK]的数量,没有动力转向压力PK保持在预定的时间周期不变,然后在发动机已经停止运行后的预定时间段过去之后,功率 转向压力PK,在该检测D [PK]的数目达到最大值,被采用作为压力传感器的零压力值。 这使得可以精确地设置压力传感器的正确零压力值在液压动力转向装置。
