Abstract
An engine control device controls an engine of a motor vehicle. The engine control device predefines an admissible engine torque on the basis of a torque envelope curve in dependence on an accelerator pedal position and an engine speed. The engine control device is connected to a diagnostic device. An intervention variable, that represents an engine torque and/or an engine speed and on the basis of which the engine can be actuated for test/diagnostic purposes, can be predefined for the engine control device by the diagnostic device. When at least one test criterion is fulfilled in the engine control device and/or the diagnostic device, the torque envelope curve of the engine control device can be widened or bypassed for test/diagnostic purposes in such a way that given an unactivated accelerator pedal for a defined engine torque at the request of the diagnostic device a larger engine torque is admissible.
