Method for controlling an automatic shut-off process and/or start-up process of an internal combustion engine in a motor vehicle

A method for controlling at least one of an automatic shut-off and start-up process of an internal combustion engine in a motor vehicle having a start/stop device, the method comprising the acts of:

• automatically shutting-off the internal combustion engine after driving the motor vehicle upon stopping the motor vehicle when predetermined shut-off conditions are met by corresponding influencing variables;
• automatically starting-up the internal combustion engine after being automatically shut-off when predetermined start-up conditions are satisfied by corresponding influencing variables;
• and
• wherein at least one of the following influencing variables are evaluated to meet said at least one of the predetermined shut-off and start-up conditions:
• a) in the case of the automatic shut-off process, a presence or absence of at least one of a driver identification transmitter and a vehicle key;
• b) a current saturation state of a tank ventilation system;
• c) in the case of the automatic shut-off process, a current tank fill level of a fuel tank;
• d) an activity state of at least one of a workshop mode, a works mode, a service mode, and a production mode;
• e) an evaluation of a device for detecting occupancy of the driver's seat wherein the device for detecting occupancy of the seat is configured as at least one of a seat occupancy mat, a camera system, and a seat belt buckle evaluation system;
• f) a detection of a cylinder synchronization process;
• g) an activity state of a driving speed control system;
• h) in the case of the automatic start-up process, an activity state of an auto hold function in a motor vehicle having an automatic transmission;
• and
• i) in the case of the automatic start-up process, an activity state of a hill hold function.
