1. A logic for detecting a vehicle rollover comprisesa first main activation path that is activated if a signal of a vehicle lateral acceleration sensor exceeds a predefined threshold value;

  • a second main activation path that is activated if a signal of a vehicle vertical acceleration sensor exceeds a predefined threshold value;

    a first additional activation path that is activated if a vehicle roll angle exceeds a predefined threshold value and a signal of a vehicle roll rate sensor exceeds a predefined threshold value;

    a second additional activation path that is activated if the signal of the vehicle roll rate sensor exceeds a predefined second threshold value; and

    a third additional activation path that is activated if a signal of a vehicle longitudinal acceleration sensor exceeds a predefined threshold value;

    wherein activation of at least one of the first main activation path and the second main activation path and activation of at least one of the first additional activation path, the second additional activation path and the third additional activation path is needed for activation of the logic.
