1. A method for recognizing a defect in a drive system of a motor vehicle equipped with an electronically controllable brake control system, the drive system having an electronically controllable driving engine, an electronically controllable clutch and/or an electronically controllable transmission, wherein the method comprises the acts of:

  • assigning an electronic braking control device to the brake control system, the braking control device being connected with an independent monitoring module;

    determining, via the independent monitoring module, an occurrence of an implausible braking torque;

    determining, via the independent monitoring module, that the implausible braking torque was caused by a defect in at least one of the electronically controllable driving engine, the electronically controllable clutch and the electronically controllable transmission, and not by the electronically controllable brake control system;

    upon receiving a defined defect signal from the independent monitoring module, interrupting, via an electronic control device of the drive system, (i) a power connection between the driving engine and driven wheels of the motor vehicle, or (ii) a power transmission of the driving engine.
