Embodiment Construction

[0030] Just like in Figure 1, image 3 A parking space search is shown while vehicle 10 is driving past a parking space extending between two vehicles 30 , 40 arranged at the edge of a roadway. In contrast to the illustration in FIG. 1 , ultrasonic sensor 20 mounted on the side of vehicle 10 has a reduced effective opening angle. Detection range 22 of ultrasonic sensor 20 , which is also reduced as a result of the reduced opening angle of ultrasonic sensor 20 , is at image 3 drawn in. exist image 3 In , the distance value of the actual distance between the ultrasonic sensor 20 and the vehicle 40 is marked with d0.

[0031] image 3 Also shown is a detection region 21 , which the ultrasonic sensor 20 has at large opening angles, for example between −60° and +−60°, which is comparable to the previously mentioned detection region 22 —the ultrasonic sensor 20 . This detection range is present in the case of a reduced effective opening angle between −15° and +−15°, for example—f...

Abstract

The invention relates to a method for detecting a parking space extending between objects arranged laterally at the edge of a roadway, wherein, during the passing of a vehicle (10) along the objects (30, 40), Ultrasonic pulses are transmitted by means of ultrasonic sensors (20) mounted on the side of the vehicle (10), ultrasonic pulses which are transmitted and reflected at the objects (30, 40), called echo pulses, are received and The received echo pulses generate an electrical receive signal. In this case, the electrical reception signal is evaluated for detecting a parking space extending between the objects ( 30 , 40 ). Furthermore, in the band-pass filtering of the first of the received signals, received signals from echo pulses which are not Doppler-shifted with respect to the transmitted ultrasound pulses of the first received signal are allowed to pass through . The received signals of the first received signals that are passed in the first bandpass filter are also evaluated for detecting the object ( 30 , 40 ) located on the roadway facing the object ( 30 , 40 ). Object edges and / or object corners (31, 41) on one side of .

Description

technical field [0001] The invention relates to a device or a method for detecting a parking space extending between objects arranged laterally at the edge of a roadway. The invention also relates to a vehicle having a device according to the invention. Background technique [0002] It is known from the prior art to search for parking spaces extending between objects arranged at the edge of a roadway by means of ultrasonic sensors mounted on the side of the vehicle. [0003] FIG. 1 shows a vehicle 10 having a laterally mounted ultrasonic sensor 20 with a large opening angle. In FIG. 1 , a large detection region 21 of the ultrasonic sensor 20 is also drawn as a result of the large opening angle of the ultrasonic sensor. FIG. 1 shows the search for a parking space while a vehicle 10 is driving past a parking space extending between two objects or vehicles 30 , 40 arranged at the edge of a roadway. In this case, the sensor 20 mounted on the side of the vehicle 10 is guided a...
