摘要:
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.
摘要:
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:
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: (a) Adaptively determining the background signal (S0) by localized filtering of the output or base signal (S) using at least one localized filter having a specified width (B); (b) Correcting the background of the output or base signal (s) by (b.1) subtracting the determined background signal (S0) from the output or base signal (S) and (b.2) forming a signal, in particular (s=abs (S−S0)), for example, from the difference (S−S0) of the output or base signal (S) and the background signal (S0); (c) Low-pass filtering, in particular temporal low-pass filtering, of the absolute value signal (s); (d) Forming a correlation signal (k=korr(s)) by correlating, in particular folding, the low-pass filtered absolute value signal (s) with at least one reference maximum having a half-value width; and (e) Determining the at least one object maximum (M) using at least one location-variable, adaptive threshold value (t) which may be determined from the correlation signal (k).
摘要:
A system for detecting objects, in particular for a motor vehicle, is proposed in which, with a radar sensor, the radar signals reflected by the object are processed for ascertaining the distance (d) and/or the relative or approach speed (Cv) of the object. The digital signals from at least one channel (I, Q) of the radar sensor are processed until a first evaluation capability is obtained as a distance signal (d) or as an approach speed signal (Cv), with which it is defined which data are ascertained and will be made available to an interface (6) between the radar sensor and a downstream control unit (7).

In an optical short-range sensor, a plurality of sequentially actuatable transmission elements (21 . . . 27) disposed in a line-like manner in one plane is provided. At least one additional transmission element (1) situated offset in relation to the sequentially actuatable transmission elements and in particular transmitting downward, is provided. In a receiver device (3), the signals reflected by objects are evaluated in particular by propagation time measurement.
摘要:
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.
