摘要:
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.

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.

A method for operating a parking assistance system and a parking assistance system for a vehicle, is characterized by the following steps: a) determination of the length and/or width of a parking space when passing the parking space; b) determination of at least one feasible parking process for the vehicle for entering into or exiting the parking space; c) instructing the driver as to which direction the vehicle shall be moved and how far the steering wheel must be turned, and d) automatic braking and/or acceleration of the vehicle during the parking process into or out of a parking space, wherein steps c) and d) can be effected in any order, one after the other and/or at the same time.

The invention relates to a method for operating a parking assistance system for a vehicle, comprising at least one distance sensor that detects at least sections of the lateral immediate vicinity of the vehicle and at least one path sensor that detects the path travelled by the vehicle. According to the method, a control device determines the length and/or width of a parking space from the values measured by the sensors as the vehicle drives past said parking space. The invention is characterised in that the measured length and/or width of the parking space is/are corrected by a correction value and/or that depending on the speed of the vehicle as it drives past the parking space, the measurement is taken by means of the distance sensor at different time intervals.

摘要:
A method is described for assisting a driver of a vehicle (01) in exiting from a lateral parking space (02) in a longitudinal direction with respect to a roadway, comprising the method steps: starting of the method when a parking space (02) is to be exited longitudinally with respect to a roadway; measuring of at least the length (D) of the parking space (02); determination of a parking-space-exiting trajectory (03) at least on the basis of the data acquired by means of the measurement; starting of the parking-space-exiting process; carrying out of the parking-space-exiting process with simultaneous collision prevention by monitoring the distance from at least objects (05, 07, 08) which bound the parking space (02); and ending of the method as soon as collision-free exiting from the parking space (02) is possible. Furthermore, a driving assistance device for carrying out the method and a computer program product which causes a microprocessor with associated storage means to carry out the method are described.
