Abstract
A method for operating a switch valve which opens and closes a fluid line is disclosed. The switch valve is actuated by a pulse width modulated signal. The switch valve is actuated outside of the active operating time of the switch valve using PWM signals with an increasing or decreasing duty cycle. The duty cycle in which the switch valve is opened is determined, and the duty cycle corresponding to the opening time is then used to actuate the switch valve to open and close the switch valve during the active operating time of same. In this manner, the switch valve can be actuated in a particularly precise manner.
