The present invention relates to a logic unit and a method for detecting vehicle rollover or dangerous situations that may precede a rollover of a vehicle. The logic unit (1) is preferably connected with at least one protection device for an occupant of a vehicle and comprises the first main activation path (2), which is activated if a signal of a vehicle lateral acceleration sensor (21) exceeds a predefined threshold (22); the second main activation path (3), which is activated if a signal of a vehicle vertical acceleration sensor (31) exceeds a predefined threshold (32); and the first additional activation path (4), which is activated if a vehicle roll angle exceeds a predefined threshold (42a) and a signal of a vehicle roll rate sensor (51) exceeds a predefined threshold (42b); the second additional activation path (5), which is activated if a signal of a vehicle roll rate sensor (51) exceeds a predefined second threshold (52); the third additional activation path (6), which is activated if a signal of a vehicle longitudinal acceleration sensor (61) exceeds a predefined threshold (62), wherein the activation of the logic unit (1) depends on the activation of individual activation paths and for the activation of the logic (1) at least one main activation path must be activated. Preferably the activation of at least one main activation path (2, 3) and at least one additional activation path (4, 5, 6) is sufficient for the activation of the logic unit (1). <IMAGE> |
