Abstract: The invention relates to method and a device for determining the projected distance between a distance measuring device and a nearest point on the surface of an obstacle, the projected distance between said point and the distance measuring device being fundamentally the shortest in relation to all points of the obstacle. The aim of the invention is to be able to calculate the current distance between the nearest point and the distance measuring device, when the point P is no longer inside the detection region of the distance measuring device. According to the invention, the calculation of the projected distance is based on information about the relative movement of the distance measuring device and the obstacle, and on a defined limiting distance.

Abstract: A method and a device for monitoring a space for the presence of a foreign body comprises at least one transmitter and a first and second receiving device. The signal of the second receiving device which is spaced further apart from the transmitter than the first receiving device is evaluated for its parasitic signal portions. If the distance between the first and the second receiving device is not too great, it can be assumed that parasitic signal portions detected in the second received signal are also contained in the first received signal. In this case, it is recommended to discontinue monitoring the space or to discard any result of this monitoring already obtained at least until no parasitic signal portions are detected in a repeated evaluation of the second received signal.

Abstract: The invention relates to a method for detecting the contour of an obstacle in the surroundings of a moving vehicle by means of a sensor device that is preferably integrated in the lateral area of the vehicle. In previously known methods of this type, the sensor device usually emits a sensor signal to the obstacle already when said obstacle lies ahead in the direction of travel while also emitting a sensor signal once the vehicle has passed the obstacle. In order to improve evaluation of the sensor signals with regard to the reflection thereof on the obstacle, the reflection signals thus generated are first mathematically averaged so as to be able to then derive in a more precise manner the actual position and the actual shape of the contour of the obstacle from the obtained averaged reflection signal.

Abstract: The invention relates to a method for determining the position (x, y) of at least one point of reflection (R1-2) on an obstacle. According to traditional methods of this kind a first distance (r1) between the point of reflection (R1-2) and a first position (x1) of a distance measuring device is calculated by evaluating a time period between the emission of a transmission signal and reception of a reflection signal. In order to state the unsharp position of the point of reflection thereby obtained even more precisely, in addition to the first distance (r1), a second distance (r2) of the point of reflection is calculated with respect to a second position (x2) of the distance measuring device in analogy to the calculation of the first distance (r1) and then a defined position (x, y) is calculated from the pair of variates (x1, r1) (x2, r2) so obtained using the triangulation method.

Abstract: The invention relates to a method and a device for monitoring a space for the presence of a foreign body. The monitoring device usually comprises at least one transmitter and a first and second receiving device. Conventional methods for evaluating the signals received by the receiving devices only allow for a limited statement as to whether the received signals possibly contain parasitic signal portions which would falsify an evaluation with respect to the presence of a foreign body. The aim of the invention is therefore to provide a method and device which improve the reliability of such a statement. For this purpose, the signal of the second receiving device which is spaced further apart from the transmitter than the first receiving device is evaluated for its parasitic signal portions. If the distance between the first and the second receiving device is not too great, it can be assumed that parasitic signal portions detected in the second received signal are also contained in the first received signal.
