    • A method for detecting a malfunction in an electromagnetic retarder. More specifically, the method relates to a retarder comprising: stator primary coils (8); a control unit (19) for injecting a current into the primary coils (8), the current having an intensity corresponding to an intensity set value (Ci); a sensor (21) which delivers a signal that is representative of an effective intensity value (Ie) of the current passing through the primary coils (8); and a shaft (7) bearing secondary windings (5) defining several phases and field coils (13), as well as a current rectifier (5) which is disposed between the secondary windings (5A, 5B, 5C) and the field coils (13). The method consists in comparing the intensity set value (Ci) and the effective intensity (Ie) in the control unit (19) in order to identify a fault in the event that the intensity set value (Ci) and the effective intensity (Ie) differ by an amount greater than a threshold value. The method is suitable for electric retarders (1) which are intended for heavy vehicles, such as trucks or other vehicles.

    • A method for controlling an electromagnetic retarder. More specifically, the method relates to determining, in a control unit, a maximum allowable intensity (Im) of an excitation current to be injected into an electromagnetic retarder (1). The retarder includes a shaft bearing secondary windings (5) and field coils (13) which are supplied by the secondary windings (5), the primary coils (8) and secondary windings (5) forming a generator. The retarder also includes a jacket (9) inside which the field coils (13) generate Foucault currents and a circuit for the liquid cooling of said jacket. The method consists in determining the maximum intensity in real time from data and values that are representative of the speed of rotation of the rotary shaft, the heat load that the cooling circuit can dissipate and the flow rate (D) of the coolant. The method is suitable for electromagnetic retarders which are intended for vehicles such as heavy vehicles.
