The invention relates to a scanning opto-electronic detection device and a method for sensing the surroundings of a motor vehicleby scanning by means of an opto-electronic detection device. The detection devicecomprises a transmission and reception optical systemthat outputs electromagnetic rays and maps reflected rays on a detector, wherein the detector is of multiline design and comprises a plurality of detector cells for providing electrical received signals on the basis of received reflected rays, which detector cells are lined up in a detector cell stack and are evaluable in parallel measurement planes. The detection device furthermore comprises a mirror carrierhaving mirror facesthat are averted from one another and that are arranged in a manner tilted at a tilt angle with respect to an axis of rotationof the mirror carrierand map different vertical sensing regions for reflected rays onto the detector. In order to allow the surroundings of a motor vehicle to be sensed with little physical outlay by means of an opto-electronic detection device having as large a sensing region as possible, the invention provides for determined tilt angles &#x3b1; of the mirror facesthat are such that the sensing regionsintersect in a central section of a total sensing region

Opto-electronic detection device and method for sensing the surroundings of a motor vehicle by scanning

The invention relates to a method for carrying out one or more collision-avoiding measures of a vehicle, in particular a motor vehicle. In the method, the positions of static and dynamic objectsare detected in a stepand one or more trajectorieswhich avoid collisions with the detected objectsare determined for the vehicle in a stepAccording to the invention, a danger valuefor the determined trajectoryor for each of the determined trajectoriesis determined continuously or periodically in a further stepThis danger valueconstitutes a measure for the forces which act on the vehicle when the respective trajectoryis passed through. The collision-avoiding measures are then carried out in a stepif the determined danger valueor the determined danger valuesis/are above a selected or predefined threshold value In addition, the invention relates to a device for carrying out the method.

A control element for a sensor network having a set of different sensors. In operation, the control element transfers connections between the control element and the set of different sensors, where the transfer connections are compliant with respective sensor-specific protocols. A sensor controller element is provided for each sensor, and establishes transfer connections between the control element and new sensors in runtime. Information obtained in a sensor-specific protocol format from the sensors is converted into a common format in the sensor controller elements. The common format information is processed by a set of common control components of the control element. The control element provides a service based on the information in the common format to at least one consumer, and updates the service in accordance with the sensors present in the sensor network.
