  • Patent number: 7565242
    Abstract: A method and a device for triggering emergency braking of a vehicle for avoiding a collision or for reducing the severity of a collision, the vehicle having at least one object detection sensor, an ascertainment being made as a function of the detected objects as to whether a collision with an object is imminent and a risk to one's own vehicle in the event of a triggering of emergency braking being ascertained as a function of the current surrounding situation, the triggering threshold for emergency braking being variable in such a way that the probability for a false triggering is increased if a calculated risk posed by emergency braking is low and the triggering threshold for emergency braking being variable in such a way that the probability for a false triggering is lowered if a calculated risk posed by emergency braking is higher.

  • Publication number: 20090038873
    Abstract: A method and a device for controlling automatic emergency braking of a motor vehicle to reduce the severity of a collision of a vehicle with an object, the position and/or speed of the object with respect to the host vehicle being determined via an object detection device, and this information being sent to a collision detection device which ascertains whether a collision with an object is imminent and, on detecting a collision, triggers emergency braking and ascertains a collision instant, emergency braking being terminated after the period of time until the determined collision instant has elapsed.

  • Patent number: 7382031
    Abstract: A method and device are for anchoring fixed structural elements and, e.g., for anchoring electrodes for components, e.g., SOI wafer components, whose component structure is formed in a silicon layer on top of a substrate used as support. The fixed element may be mechanically connected to the substrate via at least one anchoring element made of an anchoring material and extending through the silicon layer. In the case of an SOI wafer, the anchoring element may extend through the silicon layer and the sacrificial layer of the SOI wafer. To this end, in the area of the surface of the fixed element, at least one recess is made in the silicon layer, which may extend through the entire silicon layer and the sacrificial layer down to the substrate. The recess may then be filled with an anchoring material, so that the fixed element is mechanically connected to the substrate via the anchoring element that is thereby created.

  • Patent number: 7363155
    Abstract: A method and a device for warning the driver of a motor vehicle about a traffic situation involving an increased collision risk are provided. For this purpose, signals of at least one object detector representing motion quantities of detected objects and signals of at least one motion sensor system of the host vehicle are suppliable to an analyzer device. The computing device precalculates all possible motion trajectories for all detected objects and for the host vehicle, taking into account maximum acceleration or deceleration values and maximum change in acceleration or deceleration values over time and, when an imminent collision is recognized, issues a warning to the driver that higher acceleration or deceleration values and/or change in acceleration or deceleration values are needed to avoid a collision.

  • Patent number: 7270868
    Abstract: A component having a surface micromechanical structure containing both movable elements and immovable elements, and a method of manufacturing same are described. The surface micromechanical structure of the component is produced in a functional layer, which is connected to a substrate via at least one electrically non-conductive first insulation layer and at least one first sacrificial layer. The movable elements of the surface micromechanical structure are exposed by removing the first sacrificial layer. The first insulation layer is made of a material which is not substantially attacked by the process of removing the first sacrificial layer. Thus the removal of the sacrificial layer may be limited in a design-controlled manner. At the same time, a reliable electrical insulation of the surface micromechanical structure with respect to the substrate of the component and a reliable mechanical fastening of the immovable elements of the surface micromechanical structure to the substrate are ensured.

  • Publication number: 20070185634
    Abstract: In a method and a system for controlling a driver-assistance device, in which measured quantities to be recorded by sensors are evaluated for triggering a reaction, and measuring instants are determined through essentially repeating cycles for acquiring and evaluating the measured quantities, the measuring instants are controlled in such a way that one of the measuring instants follows as immediately as possible an instant at which measured quantities giving rise to a triggering probably exist.

  • Publication number: 20070075850
    Abstract: A method and a device for warning the driver of a motor vehicle. An object detector is provided, which detects preceding vehicles and ascertains their distance and relative velocity with respect to the host vehicle and supplies these to an evaluation device. The evaluation device assumes that the preceding vehicle would perform a deceleration and ascertains as a further function of the variables measured by the object detector and the driver's reaction time and the host vehicle's maximum possible deceleration whether a collision with the preceding vehicle would be avoidable. If an unavoidability of a collision is recognized, then a driver warning device is activated.

  • Patent number: 7035735
    Abstract: A method and a device for automatically triggering a deceleration of a vehicle so as to prevent a collision with another object. Objects in the range of the vehicle's course being detected using signals of an apparatus for sending and receiving radar signals or lidar signals, or of an apparatus for receiving video signals. An endangerment potential is determined as a function of the objects detected, and when a predefined endangerment potential theshold value, which may be less than the triggering threshold value for the deceleration, is exceeded, the deceleration means of the vehicle are reset to a state in preparation for braking. Furthermore, additional vehicle functions may be carried out when the endangerment potential threshold value is exceeded, whereby passenger safety in this travel situation is enhanced.

  • Patent number: 7015805
    Abstract: A method and a device for controlling deceleration devices of a vehicle during a braking operation, e.g., a vehicle which is equipped with a sensor for adaptive cruise control. During the braking operation, risk dimensions are determined on the basis of driving dynamics models, which are individualized by signals of the surrounding-field sensor system. A first risk dimension is precalculated for the case of continued deceleration and a second risk dimension is precalculated for the case of unbraked further movement of the vehicle. Through the comparison of the two risk dimensions, it is decided whether the automatic vehicle deceleration is to be maintained or whether the braking is to be canceled before the vehicle is brought to a standstill.

  • Patent number: 6856906
    Abstract: A method and a device for triggering and implementing a deceleration of a vehicle to avoid a collision, in which, using a device for adaptive cruise control, objects in the sensor detection range are detected and measured variables are determined for each detected object. The detected objects are assigned to various object classes on the basis of the determined, associated measured variables, and the movement trajectories of the objects are predicted on the basis of the assignment of the detected objects to the particular class. Furthermore, a collision risk and an injury risk are determined from these predicted movement trajectories of the objects and the associated, detected object classes. In the event of the existence of preselected combinations of collision risks and injury risks, the deceleration devices of the vehicle are activated as a function of the degree of the collision risk.
