In a method for controlling an electromagnetic valve, the temperature of the valve is detected, and activation of and/or the current feed to the valve are performed as a function of the temperature of the valve.

Device and method for controlling an electromagnetic valve

In a device for controlling an electromagnetic valve, input device(s) write a multitude of measured values for the current and/or the voltage into a first memory to represent a characteristic. Analysis device(s) perform a state analysis and/or a change-over-time analysis. On the basis of the state analysis and/or the change-over-time analysis, evaluation device(s) correct at least one control variable, which characterizes the control, and write it into a second memory. Control device(s) control an output stage on the basis of the control variables.

Device for controlling an electromagnetic valve

A procedure for checking the functionality of an electric heating device () with at least one PTC-element () is suggested. The electric heating device () is operated at a battery voltage. When controlling the heating device () it is impinged with a current and at least one measuring value is detected, which represents the current that flows through the heating device. The measuring value for the current is compared to at least one reference value with a default tolerance width while considering the battery voltage. In the case of a measuring value that deviates from the reference value an error can be assumed.
