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 regulating or control unit actuates a stop/start unit for an internal-combustion engine in a motor vehicle. At least one sensor is provided for detecting at least one parameter which is dependent on a steering wheel position of the motor vehicle. The regulating or control unit actuates the stop/start unit as a function of the detected parameter information.

Abstract: A control method for an internal-combustion engine, working with a variable stopping delay. The stopping delay is essentially affected by the following parameters: the operational mode selected for the internal-combustion engine, the previous driving mode based on a driver-type classification, the past speed profile, the navigational data of GPS-systems, traffic guiding systems and digital street maps, and the actual braking pressure.

Abstract: A method and a device for automatically starting an internal combustion engine having a brake pressure monitoring system and an arrangement evaluating the brake pressure with respect to its profile over time. The brake pressure gradient is evaluated when the brake pedal is released before the vehicle is restarted. If the absolute value of the negative brake pressure gradient when the brakes are released exceeds a threshold value, this upward transgression of the threshold value causes an electronic control system in the motor vehicle to restart the internal combustion engine in conjunction with a start/stop function. The main advantage which is achieved in this way is that the brake pressure gradient precedes the point at which the brake pressure reaches its position of rest so that a vehicle driver can sense the restarting of the internal combustion engine to be more spontaneous than in the prior art.
