A method for mapping surroundings of a vehicle, objects in the surroundings of the vehicle being detected with the aid of sensors and particular detected objects being described by two coordinate points and also by a position fuzziness assigned to the particular coordinate point, the coordinate points and the position fuzziness values being stored in an interface in the form of data which may be accessed by driver assistance systems of the vehicle. A method is also described for ascertaining the collision probability of a vehicle with an object, in which the surroundings of the vehicle are initially mapped using the method for mapping the surroundings of a vehicle, a travel path to be traveled by the vehicle is ascertained in a subsequent step, and the degree of overlap between the object and the travel path and also the collision probability are finally determined, taking the position fuzziness into account.

Method for mapping the surroundings of a vehicle

A control unit for automatically guiding a vehicle, in particular during a parking procedure, has an interface to a monitoring unit of a brake operating unit of the vehicle to ascertain a braking readiness of the driver in such a way that automatic guiding of the vehicle is interrupted if a braking readiness of a driver is not detected.

Control unit and method for automatically guiding a vehicle

A sensor unit, in particular a sensor unit in or on a vehicle, for capacitively ascertaining the distance between the sensor device and an object, having an electrode for forming a capacitive system with the object and an apparatus for creating a signal proportional to the capacitance of the capacitive system. The sensor unit has a reference electrode for forming a capacitive reference system with the object, an additional apparatus for creating a reference signal proportional to the capacitance of the capacitive reference system, and an analyzer device for ascertaining the distance by forming a ratio of the signal and the reference signal, the reference electrodes having an electrode shape, which is different from the electrode shape of the electrode.

Sensor device for capacitively ascertaining distance

A device for approving automatic guidance of a vehicle, having an interface to a monitoring apparatus for at least partially monitoring a vehicle driver located in the vehicle, having an interface to an apparatus for automatically guiding the vehicle and for ascertaining a travel direction of the vehicle when automatic guidance is to be performed, and having an analysis unit for comparing a field of vision of the driver, which is determined from the monitoring of the driver, to the travel direction of the vehicle during the automatic guidance, automatic guidance only being approved if the travel direction of the vehicle during the automatic guidance is in the field of vision of the driver.

Device and method for approving automatic guidance of a vehicle

A device for measuring a parking space as a vehicle drives past the parking space includes a depth-measuring line scan camera movable together with the vehicle for acquiring individual images of the environment surrounding the vehicle transverse to a longitudinal direction of the vehicle, an arrangement for acquiring the movement of the vehicle, and an evaluation device. The individual images of the environment surrounding the vehicle contain depth information that is resolvable in a vertical direction.

Device and method for measuring a parking space

A driver assistance system includes a distance measuring device which detects distance values of objects from the surroundings of a vehicle. Based on a coordinate system that is fixed to the vehicle, the surroundings of the vehicle are subdivided into zones. Individual quality measures are assigned to distance values from the particular zones or measured quantities derived from these distance values. The individual quality measure is a function in particular of the variation of the component of the relative velocity in the longitudinal direction of the vehicle.

Driver assistance system

A method for the detection of surroundings is performed using a source which emits pulsed signals. Signals backscattered from an object are detected by a sensor. When performing the method, a presence of the object is detected during coarse sampling. To determine a variable related to the detected object, operating parameters of the source are set for fine sampling.

Method for the detection of surroundings

An object detection system, in particular for a motor vehicle, has multiple object detectors and/or operating modes with which different detection ranges and/or detection zones are detected. In this case, an object detector is preferably a radar sensor which has a relatively large detection range with a relatively small angular detection zone in a first operating mode and has a detection range that is small relative to the first with an enlarged angular detection zone in a second operating mode.

Object detection system

A control/evaluation system for a set of sensors, in particular in motor vehicles, has a plurality of areas, each of which has at least one controller and a plurality of sensor devices connected thereto; the controllers may be connected to each other for a common application function.

Control and evaluation system for a compound sensor

A method for object detection using vehicle-mounted sensors is provided, the sensing ranges of which sensors overlap at least partially. In this context, signals of at least two sensors having sensing ranges with essentially identical coverage, and additional signals of at least one additional sensor having a sensing range which only partially overlaps with the sensing ranges of the at least two sensors, are evaluated. An object is identified as relevant when it is detected by at least three of the sensors.

Vehicle mounted system for detecting objects

To provide a method of processing output or base signals (S), in particular intermediate frequency output or base signals, from at least one device, in particular at least one radar device, for determining a distance (d), in particular a small distance on the order of magnitude of approximately zero meters to approximately 7 meters, of an object, by which it is possible to obtain from the raw signals, i.e., the output or base signals, distance information with respect to at least one object located in the detection or sensing range of the device, the following steps are provided:

Method for processing output or base signals from a device for determining a distance of an object

In order to refine a method, as well as a system for detecting at least one object, in particular for detecting its specific parameters such as the relative position of the object or the relative speed of the object, such that the objects to be detected may be classified with respect to their spatial dimensioning, in particular with respect to their lateral extension, the spatial, in particular the lateral, extension of the object is detected using at least three distance-resolving units, mounted in particular on a means of transportation.

Method for identifying obstacles for a motor vehicle, using at least three distance sensors for identifying the lateral extension of an object

A cruise controller is provided, which regulates the driving speed of the vehicle not only beyond a certain minimum speed but also at speeds below a preselected critical speed down to standstill of the vehicle. Detecting the traffic situation using a distance sensor allows the vehicle to be automatically started once the driver has responded to a corresponding starting instruction. The starting instruction is effective until a preselected time limit, but, alternatively may also be repeated. However, in any traffic situation, the driver may override the cruise controller by operating the accelerator pedal or the brake pedal.

Speed controller for a motor vehicle

A method and a device for detecting objects that has at least two near distance sensors installed on a vehicle. The at least two near distance sensors have detection ranges that overlap at least partially. The relative positions of possible detected objects with respect to the at least two near distance sensors are determined in the overlap area by the triangulation principle. Possible apparent objects obtained by determining the relative position of possible detected objects are identified using dynamic object monitoring.
