Abstract:
1. A method for actuating an electromagnetic valve, the electromagnetic valve having at least two switching states, one of the switching states being an open state, wherein switching between the switching states is effected by an electrical current, and wherein timing of the switching can be controlled by controlling a ramp-up of the electrical current, the method comprising: applying an electrical voltage to the electromagnetic valve causing the ramp-up of electrical current; and ensuring that the electromagnetic valve switches to the open state during the ramp-up of electrical current by clocking the electrical voltage if without clocking the electromagnetic valve would switch to the open state outside of the ramp-up, wherein a signal corresponding to a current profile is determined by a measurement resistor and amplified by a differential amplifier, and wherein the signal can be converted to a digital signal and evaluated by a control device, the control device being able to control the switching process.
