Embodiment Construction

[0037] figure 1 A motor vehicle 1 according to an exemplary embodiment of the invention is shown in plan view. Motor vehicle 1 is designed in the present case as a passenger car. Motor vehicle 1 includes a driver assistance system 2 with which at least one object 3 in an environment 4 of motor vehicle 1 can be detected.

[0038] Driver assistance system 2 comprises a controller 5 which may be formed, for example, by an electronic control unit (ECU) of motor vehicle 1 . Furthermore, driver assistance system 2 includes a plurality of sensors 6 , 7 . The sensors 6, 7 may be eg ultrasonic sensors, cameras, radar sensors, lidar sensors, laser scanners or the like. In the present exemplary embodiment, driver assistance system 2 comprises twelve ultrasonic sensors 6 , six of which are arranged in front area 8 and six of which are arranged in rear area 9 of motor vehicle 1 . Ultrasonic sensor 6 can be arranged, for example, on a bumper of motor vehicle 1 . Ultrasonic signals can ...

Abstract

The invention relates to a method for detecting at least one object (3) in an environment (4) of a motor vehicle (1), in which a first sensor (6) is controlled to emit a sensor signal, sensor data describing the sensor signal reflected by the at least one object (3) are received by a second sensor (6), a blurred feature (xU) is determined from the sensor data as an object feature (xP, xL, xU) fordescribing the at least one object (3), wherein the blurred feature (xU) describes a distance between the at least one object (3) and the first sensor (6) and a distance between the at least one object and the second sensor (6), wherein the blurred feature (xU) is described as an ellipse (xE), a further object feature (xP, xL) describing the at least one object (3) is determined on the basis of sensor data from at least one further measurement by the first and / or second sensor (6), the further object feature (xP, xL) and the blurred feature (xU) are converted into a common state space using aninnovation function (h), wherein the innovation function (h) describes a similarity between the blurred feature (xU) and the further object feature (xP, xL), and a combined object feature is determined from the further object feature (xP, xL) on the basis of the innovation function (h).

Description

technical field [0001] The invention relates to a method for detecting at least one object around a motor vehicle, wherein a first sensor is actuated to emit a sensor signal, sensor data is received from a second sensor, the sensor data describing a sensor signal reflected from at least one object , determining an ambiguity feature from the sensor data as an object feature describing the at least one object, wherein the ambiguity feature describes a distance between the at least one object and the first sensor and a distance between the at least one object and the second sensor. Furthermore, the invention relates to a controller and a driver assistance system for a motor vehicle. Finally, the invention relates to a motor vehicle. Background technique [0002] Various methods are known from the prior art with which objects in the surroundings of a motor vehicle can be detected. For example, objects can be detected by means of corresponding sensors, such as ultrasonic sensor...
