Abstract
In the case of a circuit arrangement in an electronic control unit of a motor vehicle for the detection of faults in an electronically controlled drive system, which is structured in at least two levels, a first function-controlling level and a second monitoring level, both levels acquire at least the accelerator pedal position as an input signal. The first level has a driver intention determination block for determining a quantity proportional to the desired longitudinal acceleration. The first level transmits this quantity as an input signal to a plausibility block of the second level. The plausibility block has at least one fault detection program, by which a fault can be detected when a defined correct relationship does not exist for a specified time period between the accelerator pedal position and/or the accelerator pedal position change with respect to the determined quantity proportional to the desired longitudinal acceleration—and this relationship is therefore implausible.
