A method and associated safety system are provided for the recognition of defects in a drive system of a motor vehicle, having an electronically controllable brake control system and having at least one electronically controlled driving engine, an electronically controllable clutch and/or having an electronically controllable transmission. An electronic braking control device is assigned to the brake control system, which braking control device is connected with an independent monitoring module. The independent monitoring module checks for an occurrence of an implausible braking torque, for detecting a defect in the drive system.

Method and safety concept for recognizing defects in a drive system of a motor vehicle

A method is provided for detecting faults in an electronically controlled drive system of a motor vehicle by way of an electronic control unit. The electronic control unit detects at least the accelerator pedal position and the longitudinal acceleration of the motor vehicle as input signals. The control unit is configured to carry out a first fault detection program independently of its actual functional scope, by which program, a fault is detected if a defined acceleration gradient, which is dependent on a change in the accelerator pedal position, is exceeded for longer than for a predefined time period.
