The invention relates to a method of evaluating a movement of a motor vehicle, in particular of a vehicle movement influencing the safety of vehicle occupants, in which the acceleration of the vehicle in at least one linear direction, in particular in the direction of a vehicle axis, is measured a multiple of times, the time change of the vehicle acceleration in the at least one linear direction is determined and the determined time change of the vehicle acceleration in the at least one linear direction is taken into account in the evaluation of the vehicle movement. The invention furthermore relates to a method of activating a vehicle safety system and to an apparatus for the evaluation of a movement of a motor vehicle.

Method of evaluating a movement of a motor vehicle

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.
