  • Patent number: 10186090
    Abstract: A method is provided for determining a collision characteristic of a vehicle collision for triggering safety means of the vehicle. The method has a step of an ascertainment of at least one determination-relevant time segment of a sensor signal representing the vehicle collision before a triggering time for a safety means. The method also has a step of a comparison of at least two features of the sensor signal in the at least one time segment with one another in order to determine the collision characteristic.

  • Patent number: 10077017
    Abstract: A device for controlling personal protection apparatus in a vehicle includes: at least one sensor unit that acquires at least one physical quantity; and evaluation and control unit which (i) produces, from the at least one acquired physical quantity, at least one signal curve that characterizes an impact, (ii) determines, as a function of an energy dissipation behavior of the vehicle, at least one temporal phase in the produced signal curve, and (iii) evaluates the at least one phase for crash classification and for a triggering decision for the personal protection apparatus. The evaluation and control unit retroactively calculates at least one feature of the energy dissipation based on a characteristic time in the signal curve that represents the end of a first temporal phase.

  • Patent number: 9792509
    Abstract: A method for determining a course of a lane of a vehicle. In this connection, a first marking course of a first marking of the lane and a second marking course of a second marking of the lane are initially recorded. The first marking course and the second marking course are subsequently checked for plausibility. Finally, the lane course is determined on the basis of a previous width of the lane and a plausible marking course in response to at least one marking course proving to be implausible in the checking step.
