Embodiment Construction

[0056] exist figure 1 An embodiment of a device 1 for improved data fusion in a motor vehicle 50 is shown in FIG. The device 1 comprises at least one sensor 2 , object recognition means 3 , fusion means 4 and control means 5 . The control device 5 has access to a memory 6 in which an environment map with objects, object positions and orientation features is stored. The fusion device 4 includes an artifact detection device 7 and likewise has access to the memory 6 . Optionally, the device 1 comprises further sensors 8, 8'.

[0057] The method according to the invention is now carried out in the device 1 as follows. At least one sensor 2 detects the environment of motor vehicle 50 . The measurement data 20 detected by the at least one sensor 2 are then forwarded by the control device 5 to the object recognition device 3 . The object recognition device 3 recognizes in the measurement data 20 objects and object positions belonging to the recognized objects. Likewise, th...

Abstract

The invention relates to a method for improved data fusion during environment detection in a motor vehicle (50), comprising the following steps: detecting (101) an environment (40) of the motor vehicle (50) using at least one sensor (2); recognising (102) objects (81) in measurement data (20) detected by the at least one sensor (2); fusioning (115) of the recognised objects (81) and the object positions thereof in an environment map (80), wherein a probability of existence is / will be assigned to objects (81) recorded in the environment map (80), and wherein the probability of existence of a recorded object (81) is reduced, when a free region (86, 86.1) is measured during the detection of the position of the recorded object, wherein a respective orientation attribute (60) is assigned to theobjects (81) recorded in the environment map (80) and recorded in the environment map (80), and for a region in the sensor region (83.1, 83.2, 83.3) of the at least one sensor (2), in which a free region (86, 86.1) is measured, the probability of existence of an object (81) recorded in the region of the environment map (80) corresponding to the region is reduced in accordance with the assigned orientation attribute (60). The invention also relates to the associated device 1.

Description

technical field [0001] The present invention relates to a method and apparatus for improved data fusion for environmental detection in motor vehicles. Background technique [0002] Modern motor vehicles offer a wealth of assistance systems that support the driver when driving the motor vehicle. Such assistance systems are, for example, parking aids, which optically or acoustically provide additional information to support parking, such as the distance from adjacent motor vehicles or obstacles, and in the event of a risk of collision Send an alarm signal. Furthermore, semi-automatic and fully automatic parking aids are also known. [0003] In order to be able to provide assistance functions that specify and / or monitor the distance to adjacent motor vehicles or obstacles, the parking aid must always obtain information about the state of the environment of the motor vehicle. Usually, the environment is detected for this by means of sensors, for example by means of ultrasound...
