  • Patent number: 10227057
    Abstract: In a method for identifying misuse of a seat belt in a vehicle, vehicle data are detected and, based on said data, a plausibility check is performed for determining whether the seat belt is fastened as intended. Signals of at least one belt buckle sensor and of at least one webbing extension sensor are detected and a plausibility check for misuse is performed by taking the time course of the signals and/or the point in time of input of the signals into account so as to make a comparison with stored reference data. A seat belt system in a vehicle for carrying out said method comprises at least one belt buckle sensor and at least one webbing extension sensor as well as at least one seat occupation sensor, one door sensor, one vehicle acceleration sensor and/or one vehicle speedometer as well as a control unit in which the signals of the sensors are stored and evaluated.

  • Patent number: 10207712
    Abstract: Control system, which is adapted for application in a vehicle and intended to detect following vehicles on the basis of environmental data which are obtained from one or several environmental sensors disposed on the vehicle. The environmental sensors are adapted to provide an electronic controller of the control system with the environmental data which reflect the area in front of, laterally next to and/or behind the vehicle. The control system is at least adapted and intended to detect one or several other vehicles participating in traffic behind the own vehicle with the environmental sensors. A lane associated with each other vehicle, in which the other vehicle(s) drive(s), is detected. An occupancy of the own lane and/or of at least one adjacent lane by the other vehicle(s) is determined.

  • Publication number: 20190023303
    Abstract: A collapsible steering column assembly comprises a telescopic steering shaft that is supported within a steering column shroud. The telescopic steering shaft comprises a first shaft having a hollow end with an inwardly facing wall and a second shaft that has an end that is located within the hollow end of the first shaft. A damper device is located at the end of the second shaft that is located within the hollow end of the first shaft and includes a contact member defining a contact part that contacts the inwardly facing wall. A portion of the inwardly facing wall tapers away from the open end of the hollow end so that in the event of a collapse of the steering column assembly the damper device is forced to move along the tapered portion whereby it is increasingly deformed radially thereby to provide a resistance to further collapse of the steering column assembly.
