摘要:
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.

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.
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
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.

A monitoring circuit is provided for an energy storage device. The energy storage device has a plurality of cells which each provide a voltage between their first and second connections and are switched in series. At least two voltage measuring circuits are provided, wherein the voltage measuring circuits each measure the voltage between a first measurement input and a second measurement input. A first connection conductor connects the first terminal of the first cell to the first measurement input of a first voltage measurement circuit. A second connection conductor connects the second terminal of the first cell to the second measurement input of a first voltage measurement circuit. A first load resistor can be switched between the first measurement input of the second voltage measurement circuit and a first fixed potential.

In a method and apparatus for moving a free-swinging load that is suspended relative to a suspension point, a first path along which the load should be moved from a starting point to a destination, with a first location-dependent velocity, is provided to a processor. In the processor, a second path is automatically determined along which the suspension point should be moved with a second location-dependent velocity to cause the load to move along the first path from the starting point to the destination with the first location-dependent velocity. A movement-imparted mechanism, connected to the suspension point, is automatically controlled from the processor to move the freely-suspended load from the starting point to the destination by moving the suspension point along the second path with the second location-dependent velocity.
