Abstract:
Es wird ein Konzept zur Verankerung von unbeweglichen Strukturelementen und insbesondere zur Elektrodenverankerung für Bauelemente vorgeschlagen, deren Bauelementstruktur in einer Siliziumschicht (2) über einem als Träger dienenden Substrat (4) ausgebildet ist. Dieses Konzept eignet sich besonders für Bauelemente, die aus SOI-Wafern hergestellt werden. Erfindungsgemäß wird das unbewegliche Element (6) über mindestens ein sich durch die Siliziumschicht (2) erstreckendes Verankerungselement (7) aus einem Verankerungsmaterial mechanisch mit dem Substrat (4) verbunden. Im Falle eines SOI-Wafers erstreckt sich das Verankerungselement (7) durch die Siliziumschicht (2) und die Opferschicht (3) des SOI-Wafers. Dazu wird im Bereich der Oberfläche des unbeweglichen Elements (6) mindestens eine Ausnehmung in der Siliziumschicht (2) erzeugt, die sich durch die gesamte Siliziumschicht (2) und die Opferschicht (3) bis zum Substrat (4) erstreckt. Die Ausnehmung wird dann mit einem Verankerungsmaterial verfüllt, so dass das unbewegliche Element (6) über das dabei entstehende Verankerungselement (7) mechanisch mit dem Substrat (4) verbunden wird.
Abstract:
Safety device for motor vehicles, having an impact detection system (16) and a triggering device (26) for triggering a braking operation as a function of a signal (a) of the impact detection system, characterized in that the triggering device (26) is configured to trigger the braking operation when the impact detection system (16) indicates the start of an impact.
Abstract:
The invention relates to a method and device for initiating and executing a deceleration of a vehicle in order to avoid a collision. According to the invention, objects in a sensor detection range are detected by means of a device for regulating distance and speed of the vehicle, and measured quantities are established for each detected object. The detected objects are assigned to different object classes based on the established associated measured quantities, and the movement trajectories of the objects are predicted based on the assignment of the detected objects to the respective class. In addition, a risk of collision is determined from these predicted movement trajectories of the objects and from the associated detected object classes. In the event of a predeterminable risk of collision, the deceleration devices of the vehicle are actuated according to the degree of the risk of collision.
Abstract:
The invention relates to a method and a device for automatically releasing a deceleration in a motor vehicle in order to prevent a collision with another object. According to the invention, objects in the path of the vehicle are detected by means of signals from a device for emitting and receiving radar or lidar signals or a device for receiving video signals. A danger potential is determined according to the detected objects. If a pre-determined danger potential threshold value (SW), which is less than the release threshold value (AS) for the deceleration, is exceeded the means for decelerating the motor vehicle are placed in a state of preparation for braking. Additional vehicle functions can be carried out when the danger potential threshold value has been exceeded, whereby the passenger security in said driving situation is increased.
Abstract:
The invention relates to a method and a device for warning the driver of a motor vehicle. According to the invention, an object detector detects preceding vehicles, determines their distance and relative speed in relation to the driver's vehicle and feeds the values to an evaluation device. The evaluation device (1) assumes that the preceding vehicle (13) will decelerate (a1
Abstract:
The invention relates to a method and a device for detecting obstacles and/or traffic participants. An object (3) which is to be recognised comprises at least one individual centre of reflection (31, 32). Distance, relative speed and the capture angle in relation to the object can be determined from measuring signals based on reflections at the individual centre of reflection (31, 32). The measuring signals are statistically evaluated. Evaluation consists in comparing an actual variation of the measuring signals and an anticipated value of the variation based on an actual movement.
Abstract:
The invention relates to a method comprising steps of detecting an object in an environment of a motor vehicle, tracking the object in relation to the motor vehicle by means of a first motion model of the motor vehicle in a first phase, detecting an impact of the motor vehicle with an obstacle, and tracking the object in relation to the motor vehicle by means of a second motion model of the motor vehicle in a second phase.
