Abstract
A monitoring apparatus has a control apparatus for monitoring a cooling apparatus for a power electronics arrangement. The control apparatus has an input and an output, which input is configured to receive a temperature signal from a temperature sensor, and to determine a temperature value depending on the temperature signal, and which output is configured to output an output signal. The control apparatus performs the following steps: ascertaining at least twice a temperature value and a time value assigned to the temperature value, ascertaining a difference quotient of the change in the temperature values to the change in the assigned time values, determining the state of the cooling apparatus of the power electronics arrangement depending on the ascertained difference quotient, outputting the output signal depending on the state in order to influence the power electronics arrangement.
