Such sensors are arranged, for example, on a ceiling of the parking lot and signal by means of different colored light, whether occupied by the parking sensor parking area occupied or unoccupied.

Disclosure of the invention

The object underlying the invention is to provide a concept which allows an efficient detection of a respective occupation state of two parking area sections of the parking area opposite to a carriageway of a parking space.

This object is achieved by means of the subject matter of the independent claims. Advantageous embodiments of the invention are the subject of each dependent subclaims.

• – eine in der Leuchte integrierte Parkbelegungsdetektionseinheit, wobei die Parkbelegungsdetektionseinheit ausgebildet ist, einen jeweiligen Belegungszustand von zwei relativ zu einer Fahrbahn des Parkplatzes gegenüberliegenden Parkflächenabschnitten eines Parkplatzes zu erfassen.

According to one aspect, there is provided an apparatus for detecting a respective occupancy state of two parking area portions of the parking lot opposite to a lane of a parking lot, comprising:

• A lamp for one or more lamps,
• A parking-space detection unit integrated in the lamp, wherein the parking-space detection unit is configured to detect a respective occupancy state of two parking-space sections of a parking-lot opposite to a carriageway of the parking space.

• – Erfassen eines jeweiligen Belegungszustands der zwei Parkflächenabschnitte mittels der Parkbelegungsdetektionseinheit.

According to another aspect, there is provided a method for detecting a respective occupancy state of two parking area portions of the parking lot opposite to a lane of a parking lot using the apparatus for detecting a respective occupancy state of two parking area portions of the parking lot opposite to a lane of a parking lot, comprising the following Step:

• - Detecting a respective occupation state of the two parking area sections by means of the parking occupation detection unit.

• – eine Fahrbahn,
• – zwei relativ zur Fahrbahn gegenüberliegende Parkflächenabschnitte und
• – die Vorrichtung zum Erfassen eines jeweiligen Belegungszustands von zwei relativ zu einer Fahrbahn eines Parkplatzes gegenüberliegenden Parkflächenabschnitten des Parkplatzes.

In another aspect, there is provided a parking lot for motor vehicles, comprising:

• - a roadway,
• - Two relative to the road surface opposite parking areas and
• - The device for detecting a respective occupation state of two opposite to a carriageway of a parking lot opposite parking areas of the parking lot.

The invention is based on the finding that the above object can be achieved by using a parking occupancy detection unit for detecting the respective occupancy state, which is designed to detect a respective occupancy state of two parking area sections of a parking space opposite to a lane of the parking area. Thus, two opposite parking area sections can thus be monitored for their occupancy state by means of a single parking occupation detection unit. This means, therefore, that these two opposite parking area sections do not have to be equipped in each case with their own parking space detection unit. Thus, advantageously, a parking registration detection unit can be saved. This reduces, for example, an assembly effort, in particular an assembly time, inasmuch as now only one parking space detection unit has to be mounted, instead of two parking occupation detection units.

Due to the fact that the parking registration detection unit is integrated in the luminaire, in particular the technical effect is effected that the parking occupancy detection unit is mounted simultaneously with a mounting of the luminaire. This reduces compared to two separate assemblies assembly time, inasmuch as a mounting step is saved.

After all, therefore, the technical advantage in particular that a concept for efficiently detecting a respective occupancy state of two opposite parking area portions of a parking lot can be provided.

A luminaire in the sense of the present invention denotes a device in which a luminous means can be installed.

A lighting means in the context of the present invention denotes an electrical equipment or an electrical consumer, respectively, which is designed to generate light. The lighting means thus forms a light source.

For the purposes of the present invention, a light source is, for example, one of the following lamps: incandescent lamp, gas discharge lamp, glow lamp, energy-saving lamp, fluorescent lamp, cold cathode tube, low-pressure sodium vapor tube, high-pressure mercury vapor lamp, high-pressure sodium vapor lamp, metal halide lamp, xenon arc lamp, induction lamp, light-emitting diode.

For the purposes of the present invention, a resource means, for example, an electrical component, an assembly or an apparatus of an electrical system.

In one embodiment it is provided that the luminaire comprises one or more light sources.

According to a further embodiment, it is provided that the luminaire has a housing for the one or more lighting means, wherein the parking detection unit is arranged within the housing.

As a result, the technical advantage in particular that the parking-space detection unit can be protected by the housing is brought about. Thus, for example, advantageously an existing installation space within the housing can be used efficiently, ie both for mounting or for installation of the lighting means and the parking occupation detection unit.

According to one embodiment, it is provided that the parking occupation detection unit comprises a separate light source in order to optically signal a detected occupancy state of the parking area sections.

As a result, in particular, the technical advantage is achieved that the detected occupancy state of the parking area sections can be signaled efficiently. If, for example, a luminous means of the luminaire fails, an optical signaling of the detected occupancy state by means of the own illuminant of the parking occupancy detection unit is nevertheless made possible.

The suffix "own" before "illuminant" indicates that the illuminant is included in the parking detection unit.

An occupancy state of a parking area section indicates, in particular, whether the parking area section is occupied or unoccupied. An unoccupied parking area section may also be referred to as a free parking area section.

According to one embodiment, it is provided that the luminaire comprises a plurality of luminous means, wherein at least one of the plurality of luminous means is used for illuminating the surroundings, and wherein at least one of the plurality of luminous means is used for the optical signaling of a detected occupation state.

As a result, in particular, the technical advantage is achieved that the lamps of the lamp are used efficiently. Thus, it is not necessary, for example, for the parking-space detection unit to comprise its own lighting means. Thus, the parking occupation detection unit can be produced inexpensively and constructed less technically complex.

In one embodiment, the parking detection unit is free of its own light source for optically signaling a detected occupancy state.

According to one embodiment, it is provided that the parking-space detection unit comprises a plurality of own lighting means. Designs in connection with a light source apply analogously to several own bulbs and vice versa.

Device features result analogously from corresponding process features and vice versa. This means, in particular, that technical functionalities of the method result analogously from corresponding technical functionalities of the device and vice versa.

According to one embodiment of the parking lot, a plurality of devices are provided which are in particular identical or, for example, differently shaped.

According to one embodiment, it is provided that the parking occupancy detection unit comprises at least one environment sensor whose field of view is such that both occupancy states of the parking area sections can be detected simultaneously.

As a result, in particular, the technical advantage is achieved that the environment sensor can efficiently detect the two occupancy states of the opposite parking area sections simultaneously. A field of view can also be referred to as a detection angle. The necessary detection angle depends, in particular, on a distance of the two parking area sections from one another, that is to say in particular also from a width of the roadway. In particular, the field of view or the detection angle depends on a location within the parking space on which the device, that is to say, in particular the parking occupation detection unit, is mounted. For example, if the device is mounted on a ceiling above the roadway, the field of view or angle of capture required will depend on both To seize occupancy states simultaneously, from a ceiling height.

In another embodiment, it is provided that the parking occupation detection unit has at least one environmental sensor having a sensor surface for detecting sound or electromagnetic radiation, a fisheye lens being provided for imaging sound or electromagnetic radiation onto the sensor surface.

By providing a fisheye lens which images the sound or the electromagnetic radiation onto the sensor surface, in particular the technical advantage is brought about that environment sensors can also be used whose field of vision is not such that both occupancy states of the parking surface sections can be detected simultaneously.

For example, the environment sensor is a video sensor, so that the two parking area sections can be optically detected simultaneously by means of the fisheye lens. The electromagnetic radiation is thus light here.

Analogously, this also applies to radar radiation, infrared radiation, laser radiation. Analogously, this applies to sound, which can be ultrasound, for example. This means that even with an ultrasonic sensor, a corresponding fisheye lens is provided, which images the ultrasound onto the corresponding sensor surface of the ultrasonic sensor.

A fisheye lens according to the present invention has, for example, a focal length that is less than or equal to or equal to 16 mm. In particular, a field angle of the fisheye lens is between 180 degrees and 220 degrees.

In another embodiment, it is provided that the parking occupation detection unit comprises at least one surroundings sensor and a displacement device which is configured to move the surroundings sensor from a first position, in which an occupancy state of the one of the two parking area sections can be detected by the surroundings sensor, into a second position which an occupancy state of the other of the two parking area sections can be detected by means of the environmental sensor detectable, and vice versa.

As a result, in particular the technical advantage is brought about that an efficient detection of the corresponding occupancy state can be carried out. In particular, such an environment sensor need not necessarily be formed with a field of view which is such that both occupancy states of the parking area sections can be detected simultaneously. In particular, such an environment sensor does not necessarily have to be provided with a fisheye lens. As a result, conventional environmental sensors can also be used, which reduces costs and technical complexity, for example.

The displacement device comprises, for example, an actuator, that is to say an actuator, which can displace the environmental sensor from the first to the second or from the second to the first position. The actuator comprises, for example, a motor, in particular an electric motor.

For example, according to one embodiment, a rail is provided which guides the environment sensor. This means that the environment sensor is mounted on the rail and can be moved between the two positions.

According to one embodiment, it is provided that the parking occupancy detection unit is configured, in addition to a respective occupation state of the two parking area sections, to detect a respective occupancy state of at least one further parking area section of the parking area adjacent to one of the two parking area sections.

As a result, in particular, the technical advantage is achieved that an efficient detection of the respective occupancy states can be carried out. In particular, therefore, the additional parking area section does not have to be provided with its own parking space detection unit.

For example, according to one embodiment, the parking occupancy detection unit is configured to detect an occupancy state of at least one further parking area section in addition to the occupancy state of the two parking area sections. The displacement facility is configured to shift the surroundings sensor to a third position in which a occupancy state the further parking area section can be detected or can be detected.

That the parking occupation detection unit is designed to detect the occupancy state of the further parking area section means according to one embodiment that a field of view of the environmental sensor is such that the occupancy states of the parking area sections, ie the two opposite parking area sections and the further parking area section, can be detected simultaneously. In particular, a suitably trained fisheye lens is provided.

According to one embodiment, it is provided that the detection of the respective occupancy state of the two parking area sections comprises shifting the surroundings sensor into the first position by means of the displacement device and detecting the occupancy state of the one parking area section, and that the surroundings sensor then moves into the second position by means of the displacement device is shifted and detects the occupancy state of the other parking area section.

According to one embodiment, it is provided that the device is arranged on a ceiling above the roadway.

According to one embodiment, it is provided that the device between the two opposite parking area sections is arranged centrally on the ceiling above the roadway.

According to one embodiment, it is provided that the device between the two opposite parking surface sections is arranged centrally with a maximum deviation of 10%, in particular of a maximum of 20%, on the ceiling above the roadway.

According to one embodiment, it is provided that the lamp comprises an electrical contact for an electrical power supply of the one or more lighting means, wherein the parking detection unit is electrically connected to the electrical contact.

As a result, the technical advantage, in particular, is achieved that an efficient electrical power supply for the parking-space detection unit can be ensured. Thus, it is possible, for example, by means of a single power cable to supply both the lighting means of the lamp and the parking occupation detection unit with electrical energy. Thus, therefore, no longer two separate electrical power cable to the lamp and parking detection unit must be installed, which saves installation and installation time. In particular, it is thus advantageously possible to save material, here in particular a power cable.

An electrical energy supply comprises in particular an electrical power supply and / or an electrical power supply.

According to one embodiment, it is provided that the luminaire comprises a communication interface for communication via a communication network, wherein a communication connection is formed between the parking occupation detection unit and the communication interface, so that the parking occupation detection unit can transmit a detected occupancy state of a defined parking area via the communication interface via the communication network.

As a result, in particular the technical advantage is brought about that an efficient communication possibility for the parking registration detection unit is created. This can thus advantageously use the communication interface of the luminaire to communicate via the communication network.

Furthermore, it is thus possible in an advantageous manner that both the luminaire and the parking-space detection unit can communicate efficiently via the communication network via a common communication interface. Thus, analogously to the electric power cable, only one data cable or communication cable has to be connected to the luminaire in order to allow both devices, the luminaire and the parking detection unit, to communicate via the communication network.

The communication network includes, for example, an Ethernet communication network. For example, the communication network includes a bus system. This means, for example, that the luminaire or the parking occupancy detection unit can form a bus subscriber of the bus system. Accordingly, the luminaire and the parking detection unit may form a subscriber of the Ethernet communication network.

An environment sensor in the sense of the present invention is, for example, one of the following environment sensors: radar sensor, ultrasound sensor, lidar sensor, magnetic sensor, infrared sensor and video sensor. The phrase "at least one environment sensor" includes in particular the case that a plurality of environmental sensors are provided. If a plurality of environmental sensors are provided, they are for example different or, for example, identical.

A parking space according to the present invention may also be referred to as a parking area and serves as a storage area for vehicles. In particular, the car park forms a continuous area that has several parking spaces (in the case of a car park on private land) or parking stands (in the case of a car park on public land). The parking lot is designed according to one embodiment as a parking garage. In particular, the parking lot is designed as a garage. A parking area section is therefore in particular a parking space or a parking lot.
