Definitions
- the invention relates to a parking space recognition system for a motor vehicle, comprising a sensor device which is designed to detect at least one surface of at least one object running in a direction of travel of the motor vehicle in an environment of the motor vehicle, and with a computing device, which is formed, a gap between two detected along the direction of travel extending surfaces as a potential parking space, which can be or include at least one longitudinal parking space or at least one transverse parking space to detect with an associated parking space position.
- the invention also relates to a corresponding motor vehicle and a corresponding method for detecting a parking space.
- Available parking space detection systems detect parking spaces in the passage of a motor vehicle at the parking space. Since the range of the respective sensors in a direction transverse to the direction of travel is limited, often the depth of a potential parking space can not be detected across the direction of travel of the motor vehicle. This can when driving past a larger potential parking space
- Parking space detection systems in general also do not use a basically existing by an orientation of parked vehicles on neighboring parking spaces to the parking space on the corresponding orientation of the parking space or parking spaces, since just the ultrasound sensors typically used surfaces that are transverse to the direction of travel of the motor vehicle, in a
- Ultrasonic parking space detection system only a very rudimentary information about the potential parking space, namely, for example, the length along the direction of travel of the motor vehicle, is available.
- a method for detecting and selecting a parking space is known in which first a geometry of the parking space is detected with a contour-detecting sensors, then a suitable free area is displayed as a possible parking space and a suitable parking space is selected.
- the invention is based on the object, a parking space detection by a
- the invention relates to a parking space recognition system for a motor vehicle having at least one sensor device and at least one computing device.
- the sensor device and / or the computing device can each be an in-vehicle device, ie a sensor device or
- the sensor device is designed to detect at least one surface of at least one object running in the direction of travel of the motor vehicle in an environment of the motor vehicle.
- a surface extending along the direction of travel may in particular be understood to mean a surface running essentially parallel to the direction of travel of the motor vehicle, that is to say a surface running parallel to a predefined maximum deviation from the direction of travel.
- the predetermined maximum deviation can be, for example, 40 degrees or 20 degrees or 10 degrees.
- the sensor device can thus detect a surface of a flower box, a tree or another, for example, parked motor vehicle, which is oriented toward the road traveled by the motor vehicle.
- the computing device is designed to detect a gap between two surfaces (preferably in different positions of the motor vehicle) detected by the sensor device along the direction of travel as a potential parking space with an associated parking space position.
- the potential parking space can include or be at least one longitudinal parking space or alternatively at least one, for example at least two, transverse parking spaces.
- the recognition of the gap between the surfaces can take place on the basis of a predetermined criterion.
- the potential parking space can be recognized as such when the two surfaces are not more than a predetermined distance from each other and / or recognized as a function of detected by a position detection system of the motor vehicle position of the motor vehicle, for example, by accessing a map information.
- the parking space detection system can therefore at least one
- the computing device thus initially has no knowledge of whether the potential parking space includes a longitudinal parking space or a transverse parking space, and consequently whether a parking operation is preferably carried out with a parking longitudinal or transverse to the direction of travel of the motor vehicle when detecting the surfaces.
- the computing device can be configured to provide information about the gap identified as a potential parking space, which includes, for example, position information, to the memory device.
- the parking space detection system has a memory device, such as a database device, which is formed, the detected potential parking space in dependence on a for the parking space position in the
- Memory device for example, on a map, stored parking space information as a longitudinal parking space with space for parking at least one motor vehicle along the direction of travel of the motor vehicle when detecting, so parking in
- the memory device can also have a correspondingly designed arithmetic unit.
- the memory device and the computing device described above can be embodied either as a unit or as separate units.
- the memory device may also be designed to provide a corresponding longitudinal parking signal or a cross-park signal, so that, for example, a parking or driver assistance device of the motor vehicle receives information as to whether the motor vehicle is parked or parked in the parking space should be parked crosswise.
- Memory device is not capable of uniquely identifying the potential parking space as a longitudinal or transverse parking space.
- the corresponding driver or parking assistance system can then, for example, depending on the signal to the Driver issue an appropriate notice and / or at least partially autonomous, so partially autonomous or fully autonomous, park the vehicle in the parking space.
- the driver can be provided with a corresponding indication or a corresponding partially or fully automatic parking maneuver by a parking assistance system of the motor vehicle.
- the sensor device has or is an ultrasound sensor device. It can appropriate
- Ultrasonic sensors of the sensor device have a detection range, which viewed in the direction of travel of the motor vehicle extends in a lateral lateral region of the motor vehicle in the vicinity of the motor vehicle.
- ultrasonic sensor devices typically have a range which is insufficient for a complete detection of a parking space in the depth transverse to the direction of travel and also surfaces of objects which are transverse to the direction of travel of the motor vehicle , bad or can not be detected, so that, for example, two motor vehicles parked next to each other are not detected as separate objects, but rather as only a single object that is particularly long in the direction of travel of the motor vehicle.
- the sensor device typically have a range which is insufficient for a complete detection of a parking space in the depth transverse to the direction of travel and also surfaces of objects which are transverse to the direction of travel of the motor vehicle , bad or can not be detected, so that, for example, two motor vehicles parked next to each other are not detected as separate objects, but rather as only a single object that is particularly long in the direction of travel of the motor vehicle.
- Computing device is designed to detect the gap between the two detected running along the direction of travel surfaces alternatively to the detection as a potential parking space as a cross-parking space. This can be, for example, based on
- a gap which is smaller than a length of the motor vehicle can be recognized directly as a transverse parking space, since it is not eligible for a longitudinal parking of the motor vehicle.
- the memory device is designed, on the one hand, if the transverse parking space has been detected or in the parking space information, for example on the map, for the parking space position recognized as a cross-parking gap parking deposit that the parking space in the parking space position as a transverse parking space has been detected, and on the other hand, if the parking space was recognized as a potential parking space or to deposit in the parking space information for the parking space position recognized as a potential parking space parking gap that the parking space was detected in the parking space position as a potential parking space. It can thus the
- Parking space information is updated in response to the detection of the parking space.
- the parking space information can be stored on a card here and in the other described embodiments.
- this map may include all possible parking lots or parking areas.
- This map may include, for example, all detected parking spaces with their corresponding length in the direction of travel of a vehicle passing by the parking space and possibly also a depth transverse to the direction of travel.
- the parking space information can also have a respective information about the gap, for example, their length.
- the parking space information is updated and so the respective parking space information can be constantly expanded and updated, so that the orientation or orientation of the detected parking space can be determined.
- these can be recognized once as a potential parking space at a first time and this information for the parking space position can be stored in the storage device.
- it can now be detected by the same or another motor vehicle that a transverse parking space is present here, for example if one of the two transverse parking spaces is occupied by a parked motor vehicle and, accordingly, the detected gap between the two surfaces becomes smaller is why a longitudinal parking space for the

- Parking space information be deposited accordingly that the detected parking space was detected as a cross-parking space.
- a transverse or longitudinal parking space for a parking space position can therefore also be recognized as such when the own motor vehicle, ie the motor vehicle in which the sensor device and / or the computing device is located, parks transversely or longitudinally at the corresponding parking space position ,
- Memory device is formed to deposit in the parking space information for at least one respective parking space position, how often and especially when and / or with what confidence for the parking space position a potential parking space and / or a transverse parking space and / or a longitudinal parking space was detected.
- a potential parking space and / or a transverse parking space and / or a longitudinal parking space was detected.
- the memory device is further configured to associate the parking space position depending on the stored frequencies and / or the stored times for the detection of either a transverse parking space or a longitudinal parking space or a potential parking space.
- the stored frequencies can be evaluated using predefined criteria. For example, once detected by the computing device as a cross-parking space parking space always, so with a maximum confidence as such deposited and thus identified, whereas detecting a longitudinal parking space by the computing device already by a single detection of a cross-parking space in the Area of the longitudinal parking space must be corrected.
- corresponding confidence intervals or reliability intervals can be provided so that a predetermined frequency for detecting a parking space at a parking space position as Transverse parking space and / or longitudinal parking space is required before the storage device identifies the corresponding detected potential parking space as a transverse or longitudinal parking space.
- Storage device can be increased. Moreover, a weighting of the particular information used can be flexibly realized here, which flexibility and
- the memory device is designed to assign the parking space position of a potential parking space adjacent to a transverse parking space to assign a transverse parking space and / or a potential parking space adjacent to a longitudinal parking space to assign a longitudinal parking space. This is done on the assumption that mostly several parking spaces side by side have the same orientation or orientation.

- Speed of the motor vehicle to be coupled so that, for example, always detected and detected when the motor vehicle is moving at a speed which is less than a predetermined limit speed.
- Parking space information is updated based on a particularly large amount of data. It can thereby the parking space information for all parking space positions at which the motor vehicle passes is updated.
- the amount of data is then not limited only to an area in which the motor vehicle is to be parked, but in principle all parking spaces in which the motor vehicle drives past are detected and taken into account by the system.
- Memory device comprises or is a vehicle-external storage device.
- the parking space detection system may include a plurality of in-vehicle sensor devices and in-vehicle computing devices, wherein each one sensor device and a computing device associated with a motor vehicle are.

For example, said longitudinal park signal or the cross-park signal may be provided from the storage device to the motor vehicle. It is also possible to transmit information about the gap identified as a potential parking space from the computing device to the storage device.
