A method and an arrangement for the open-loop and/or closed-loop control of the engine power of an internal combustion engine of a motor vehicle is suggested. For checking a safety function, the arrangement intervenes in the fuel metering in the sense of reducing engine speed when an operating condition critical to safety is present. This safety function is triggered in the overrun operation of the internal combustion engine independently of the safety condition and the correct performance is checked. The safety function is detected as being defective when a unlimited metering of fuel takes place in this operating condition when the safety function is triggered.

A method for control of the engine power of an internal combustion engine of a motor vehicle wherein said control is at least one of open-loop control and closed-loop control, with the driver\s desire being electronically transmitted to an engine power actuating element and with a safety function becoming effective when there is an operating condition critical to safety in the area of said control which intervenes on the metering of fuel in the sense of reducing engine speed, the method comprising the steps of: checking the safety function by triggering the safety function during a pregiven operational phase of the engine independently of an operating condition critical to safety; and, checking the correct performance of the safety function.
