摘要： In a motor vehicle having an internal combustion engine which has an automatic start/stop device, and a controllable brake device at the start of and during an automatic stop phase, the effect of a braking torque which is greater than a threshold value is ensured. For this purpose, the brake device can increase the braking torque. The threshold value is previously calculated in such a way that the motor vehicle is reliably prevented from rolling away. As a result, the internal combustion engine can be stopped frequently, and at the same time unintentional rolling away of the motor vehicle during the stop phase can be avoided.

摘要： In a method for forming the mixture in a combustion space of an internal combustion engine, fuel is injected into the combustion space with a varying fuel mass flow during an operational cycle of the internal combustion engine. In one embodiment at least under certain engine operating conditions, three-stage fuel injection is carried out during the compression phase so that a main fuel quantity is injected in a first injection step, an additional fuel quantity with a reduced fuel mass flow is injected in a second injection step and an ignition fuel quantity is injected in a third injection step. In another embodiment, a fuel quantity is injected with a fuel mass flow which is reduced so that it falls steadily from a maximum initial value down to zero and, in accordance with a third method, a fuel quantity is injected during the induction phase with a fuel mass flow which is, at least at times, proportional to the air mass flow.
