The invention relates to a method for actuating a vehicle seat valve, the piston of which is moved from a closed position into an open position or vice versa by applying a voltage to a drive mechanism, in particular an electromagnetic drive mechanism. The power of the drive mechanism is adjusted via an effective voltage that can be changed by pulse width modulation of a pulse voltage having a constant frequency. In order to move the piston from its closed position to its open position, according to the invention, the duty ratio of the pulse width modulation is first increased from a stationary duty ratio, in particular 0%, to a starting duty ratio of less than 100%, in particular less than 50%, and is only increased to a final duty ratio, in particular to 100%, after the open position of the piston is reached and/or when a blocking which prevents the movement of the piston before the open position is reached is detected.

    本发明涉及一种用于操控车辆座椅阀的方法,车辆座椅阀的活塞通过将电压施加到驱动机构、尤其是电磁的驱动机构上从关闭位置移动到打开位置中或反之亦然。经由可通过对具有恒定频率的脉冲电压进行脉冲宽度调制改变的有效电压来调节驱动机构的功率。为了使活塞从其关闭位置朝向其打开位置移动,将脉冲宽度调制的占空比首先从尤其是0%的静止占空比提高到小于100%、尤其是小于50%的开始占空比并且在到达活塞的打开位置之后和/或在识别到阻止活塞在到达其打开位置之前的移动的阻断时才提高到最终占空比、尤其提高到100%。
