  • said temperature sensor detecting a first temperature value;

    said temperature sensor detecting at least one second temperature value after the first temperature value;

    determining a time duration between detection time points of said first and said at least one second temperature values; and

    determining said state of said brake, based on a time profile of said temperatures detected by said sensors;

    wherein said first and at least one second temperature values are detected during a brake application for determining a brake-state, which brake application is initiated by a control unit at predeterminable time points or intervals during vehicle operation, without driver intervention.
