Abstract
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.
