A method for controlling a proportional solenoid valve (28) in which the valve opening degree is controlled by excitation of a proportional solenoid, the method including: a step for generating a drive current (id) for exciting the proportional solenoid (28); reversing the polarity of the drive current (id) at a faster period than the movement of the valve body (18); and controlling the valve opening by the current level of the drive current (id). As a result, the proportional solenoid (28) is caused to generate an alternating magnetic field so as to avoid the influence of residual magnetism, and a desired valve opening is obtained by the level of the drive current (id). 一种比例螺线管阀(28)的控制方法，该比例螺线管阀的阀开度通过比例螺线管的励磁而被控制，其中，该比例螺线管阀的控制方法包含以下工序：生成对比例螺线管(28)进行励磁的驱动电流(id)；以比阀芯(18)的移动快的周期使驱动电流(id)的极性反转；以及通过驱动电流(id)的电流电平对阀开度进行控制。由此，使比例螺线管(28)产生交变磁场以避免剩磁的影响，并且通过驱动电流(id)的电平来获得希望的阀开度。
