A logic for detecting vehicle rollover includes a first main activation path activated by vehicle lateral acceleration and a second main activation path activated by vehicle vertical acceleration. The logic also includes a first additional activation path activated by vehicle roll angle, a second additional activation path activated by vehicle roll rate, and a third additional activation path activated by vehicle longitudinal acceleration. Activation of each path results from the sensor specific for that path when the output exceeds a threshold value. Logic activation occurs when at least one main activation path and at least one additional activation path are activated.

Logic and a method for detecting a vehicle rollover

A rollover detection system for a vehicle comprises at least one sensor for the detection of the angle of rotation of the vehicle and/or at least one angular rate sensor, an electronic control device connected to the sensors as well as at least one safety device which can be activated via the control device in the event of a rollover scenario detected with reference to the sensor data. At least one irreversible safety device and at least one reversible safety device are provided. The control device distinguishes between at least one stage of a lower degree of severity and at least one stage of a higher degree of severity of the rollover scenario in the detection of a respective rollover scenario with reference to the sensor data in order to activate at least one reversible safety device in the case of a lower degree of severity and to activate at least one irreversible safety device in the case of a higher degree of severity.
