Embodiment Construction

[0056]infigure 1 One embodiment of apparatus 1 showing an improved data fusion in the motor vehicle 50 is shown in the motor vehicle 50. The device 1 includes at least one sensor 2, an object recognition apparatus 3, a fusion apparatus 4, and a control device 5. The control device 5 is capable of accessing the memory 6, saved in the memory having an environment map having objects, object locations, and oriented features. The fusion apparatus 4 includes a artifact identification device 7 and can also access the memory 6. Alternatively, the device 1 includes additional sensors 8, 8 '.

[0057]The method according to the invention is now performed in device 1 as follows. At least one sensor 2 detects the environment of the motor vehicle 50. The measurement data 20 detected by at least one sensor 2 is then forwarded to the object recognition device 3 by the control device 5. The object recognition device 3 identifies the object and the object position belonging to the identified object in ...

Abstract

The invention relates to a method for improved data fusion in the detection of surroundings in a motor vehicle (50), the method comprising the steps of: detecting (101) the location of the motor vehicle (50) by means of at least one sensor (2) environment (40); identifying (102) an object (81) in measurement data (20) detected by at least one sensor (2); fusing (115) the identified object (81) with its position in the environment map (80) object locations, wherein the objects (81) stored in the environment map (80) are associated with or are associated with presence probabilities, and wherein if a free area (86) is measured at the location of the stored object upon detection , 86.1), then the probability of existence of the saved objects (81) is reduced, each of which one orientation feature (60) is associated with and saved in the environment map (80) of the object (81), And for an area in the sensor area (83.1, 83.2, 83.3) of at least one sensor (2) for which a free area (86, 86.1) is measured, in the environment map (80) stored in an area consistent with said area The presence probability of an object (81) is reduced according to the associated orientation feature (60). Furthermore, the invention relates to an associated device 1 .

Description

Technical field[0001]The present invention relates to a method and apparatus for improved data fusion in an environmental detection in a motor vehicle.Background technique[0002]Modern motor vehicles provide a rich auxiliary system that supports the driver when driving a motor vehicle. Such auxiliary system is, for example, a parking assist in providing additional information to support parking in an optical or acoustic manner, such as a spacing of adjacent motor vehicles or obstacles, and in danger of collision Alert signal. In addition, half-automated and fully automated parking assistance are known.[0003]In order to provide an auxiliary function of explaining and / or monitoring the spacing of adjacent motor vehicles or obstacles, parking assist must always obtain information about the environment of the motor vehicle. Typically, the environment is detected for this purpose, for example, by ultrasonic, radar, laser, or the like. Subsequently, according to sensor data, for example ...
