A method for acquiring a characteristic point of the stroke movement of a closure element of an injector and an injection system are described. The signal of a drive device for the closure element is used to detect the characteristic point, and specific pre-processing of this signal is carried out. The signal which is made available is tilted to the setpoint signal gradient, and a minimum or maximum of the tilted signal is determined, and the characteristic point of the stroke movement of the closure element is determined therefrom. The injection system has a sensor which is configured to make available a signal of the drive device for the characteristic point, and a computing unit which is configured to carry out the specific signal pre-processing. 描述了种用于获取喷射器的闭锁元件的往复运动的特征点的方法和种喷射系统。用于所述闭锁元件的驱动设备的信号被用于探测该特征点，并且进行这个信号的专门的处理。将被提供的信号倾斜到额定-信号斜度上，确定被倾斜的信号的最小值或者最大值并且由此获取该闭锁元件的往复运动的特征点。所述喷射系统具有传感器以及计算单元，所述传感器被设计用于为所述特征点提供该驱动设备的信号，所述计算单元被设计用于执行专门的信号处理。
