Abstract: 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.

Abstract: A method and a device are for detecting the initiation of the driving off process by a driver of a vehicle. The time derivatives of the engine torque and of the engine speed are determined, and the initiation of the driving off process is then inferred from an evaluation of these time derivative values. The detection of the driving off process can be used for releasing a brake while avoiding unintentional rolling of the vehicle when making a hill start.

Abstract: The invention relates to a method and a device for detecting the initiation of the driving off process by a driver of a vehicle. In this context, at least one variable (M, N) is determined and the initiation of the driving off process is then inferred from said variable (M, N). The engine torque (M) and/or the engine speed (N) and/or a variable ({dot over (M)}, {dot over (N)}) which is correlated with the at least one variable (M, N) to be evaluated is used as at least one measured variable. The detection of the driving off process can be used, for example, in methods and devices for avoiding unintentional rolling of the vehicle, in particular when making a hill start.

Abstract: The invention relates to a method and a device for actuating at least one wheel brake device of a vehicle for preventing inadvertent rolling. A driving off assistance mode with a predefined brake pressure reduction is activated in the at least one wheel brake device if the stationary state of the vehicle has been detected (50) and the vehicle is located (51) on an incline, when viewed in the longitudinal direction of the vehicle, and an uphill direction was detected (52) as the designated driving off direction of the vehicle. The brake pressure reduction can take place with a delay after the brake pedal has been released in such a way that the vehicle rolls back at a crawling speed.
