Problems solved by technology

[0005] If the idling speed of the internal combustion engine is not increased, especially in such emergency operating situations, the associated idling performance of the internal combustion engine is not of the quality expected by the driver
In addition, "stall / flame-off" of the internal combustion engine cannot be reliably avoided

Abstract

The invention relates to a method for regulating the idling speed of an internal combustion engine (2) of a motor vehicle (1), whereby the internal combustion engine ( 2), wherein the generator (3) is driven by means of the internal combustion engine (2) for supplying power to the on-board electrical system (4), the internal combustion engine (2) being connected to the transmission (5) of the motor vehicle (1), if detected The predetermined power demand then disconnects the connection between the internal combustion engine (2) and the transmission (5) and / or provides a predetermined braking force by means of at least one brake (9) of the motor vehicle (1).

Description

technical field [0001] The invention relates to a method for regulating the idling speed of an internal combustion engine of a motor vehicle, wherein the idling speed of the internal combustion engine is increased if a predetermined power requirement in the on-board electrical system / on-board electrical system of the motor vehicle is detected, wherein the idling speed of the internal combustion engine is increased by means of The internal combustion engine is used to drive a generator for supplying power to the vehicle electrical system, and the internal combustion engine is connected to the transmission of the motor vehicle. Furthermore, the invention relates to a device for regulating the idle speed of an internal combustion engine. Finally, the invention relates to a motor vehicle with such a device. Background technique [0002] The focus here is on internal combustion engines for motor vehicles. Motor vehicles can be driven with such an internal combustion engine. Fu...
