- Ultrasonic sensor received ultrasonic signal determined again at a later point in time and compared with the stored portion.
- a similar method is known from DE 10 2017 111 931 A1, but instead of ultrasound optical signals are used to detect an object.
- the device for object detection in the underbody area of a motor vehicle has a sensor system and an evaluation unit, the sensor system being designed as at least one radar sensor which is arranged on the motor vehicle in such a way as to emit and reflect radar radiation in the underbody area between the motor vehicle and the floor
- the evaluation unit is designed to detect the movement of an object on the basis of a detected Doppler shift.
- the device is thus possible, in particular, to detect living beings such as sleeping cats, because their breathing and heartbeat lead to a slight movement of the body, which can be detected as a Doppler shift.
- classic objects e.g. a ball
- the measurement should be carried out for a certain time in order to avoid the slow
- the measurement does not yet provide any distance information, although the power of the radar sensor is preferably set in such a way that only objects a few meters further than the motor vehicle generate significant reflection signals, since a cat 20 m away is not a relevant object represents more.
- the radar sensor is designed to work in FMCW or pulse mode.
- a transit time can also be determined and a distance measurement can also be made.
- the radar sensor is arranged on the underbody of the motor vehicle.
- the radar sensor preferably has as large a radiation angle as possible in order to scan the underbody area as broadly as possible.
- the radar sensor is designed to be retractable into the sub-floor.
- it can be protected from damage while driving.
- this is not mandatory, as it is another advantage over an ultrasonic sensor is that radar sensors are more flexible in terms of installation and can, for example, be installed behind radar-permeable parts.
- the radar sensor is designed to be rotatable, so that complete scanning of the underbody area is facilitated. It can be provided that the radar sensor can be rotated through predetermined angular ranges and the
- two radar sensors are provided, a first radar sensor being arranged in the front area of the underbody and a second radar sensor in the rear area of the underbody.
- the front radar sensor shines to the rear, whereas the rear radar sensor shines to the front. In this way, too, full-surface scanning can easily be guaranteed.
- the evaluation unit is designed in such a way, a

- an acoustic or optical device can be installed to warn or scare away the object.
- a user can be informed that the automated journey cannot be started due to an object.
- the warnings described above can also be used in a conventional, manually operated motor vehicle.
- the device has at least one further sensor system to detect objects in the underbody area and / or in the vicinity of the motor vehicle, the evaluation unit being designed to verify the data from the at least one radar sensor using the data from the further sensor system .
- 1 shows a schematic representation of a device for object recognition in a first embodiment
- 2 shows a schematic representation of a device for object recognition in a second embodiment.
- a motor vehicle 1 is shown schematically in FIG. 1.
- the motor vehicle 1 has a front side F and a rear side R. Furthermore, the motor vehicle 1 has tires 2 by means of which the motor vehicle 1 stands on a floor 3, so that an underbody area 5 is formed between an underbody 4 of the motor vehicle 1 and the floor 3.
- the motor vehicle 1 has a device 6 for object recognition in the underbody area 5, which has a radar sensor 7 and an evaluation unit 8.
- the radar sensor 7 is designed to be retractable and extendable in the sub-floor 4 and to be rotatable, which is indicated by the broken lines and the arrow.
- the evaluation unit 8 is connected to a further control device 9.
- Objects O, in particular animals, in the underbody area are intended to be detected by means of the device 6 in order to prevent injury to the objects O when the motor vehicle 1 starts up.
- the radar sensor 7 is extended and emits radar beams
- the radiation angle of the radar sensor 7 is as large as possible.
- Radar sensor 7 detects the reflected radar radiation and transmits it to the
- Evaluation unit 8 If the radar radiation hits a living object O, breathing and the heartbeat result in regular movement of the object O. This movement leads to a Doppler shift in the recorded radar signal, whereby the object O is on the radar -Sensor 7 moved too and sometimes moved away. This Doppler movement is recorded in the evaluation unit 8. If an object O is then detected, the
- Control device 9 a warning device can be controlled to generate an acoustic horn signal. A motor vehicle driver can also be informed. Furthermore, the control device 9 can be designed to prevent the motor vehicle 1 from starting, which is important in particular in the case of motor vehicles 1 that drive automatically.
- the radar sensor 7 is preferably designed to work in FMCW mode, as such
- a radar image of the underbody area 5 can be recorded and stored as a reference. Before the motor vehicle 1 is started, the current radar image can then be compared with this reference.
- data from further sensors 10 can be used, which are designed, for example, as ultrasonic sensors or cameras, in order to detect the immediate vehicle surroundings or also the underbody area 5.
