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.

Abstract: In a method for detecting the charge balance of a storage battery for an electric drive vehicle by measuring and summing the charge and discharge currents over time, a plurality of current measuring arrangements are provided. Individual electrical power consumers are each assigned to one of these current measuring arrangements, and the currents detected by the current measuring arrangements are added over time. The consumers are assigned mainly on the basis of their power draws. It is also possible to replace one or more current measuring arrangements by a pulse generator. The power draw of the corresponding consumer is then multiplied by its operating time, determined with a given factor. The current draw of the electric drive is measured in any case.
