The invention is based on the realization that the above object can be achieved by switching off one or more electrical consumers of an area of the parking area when this area is completely free, ie when no motor vehicles are parked in the parking spaces within the area.

As a result, the technical advantage in particular that the electrical energy consumption of the parking space can be reduced efficiently.

The fact that the traffic is routed to a partially occupied area when there is a completely free area causes, in particular, the technical advantage that it can be effectively prevented that motor vehicles park in the completely free area with the electrical consumers switched off In turn, this would mean that the electrical consumers would have to be switched on again, which would make energy savings again nullified.

In summary, therefore, the technical advantage is provided that an efficient concept for efficiently reducing an electrical energy consumption of a parking space is provided.

A completely free area in the sense of the description designates an area of the parking space within which no motor vehicles are parked on the parking spaces. This means, in particular, that all or all parking spaces of a completely free area are unoccupied, ie free.

A partially occupied area designates an area of the parking space within which at least one occupied parking space and at least one free parking space is available.

An occupied area refers to an area of the parking area within which there are no more vacant parking spaces. This means that an occupied area has only occupied parking spaces. The occupied area can also be referred to as a fully occupied area.

A fully occupied area thus has an occupancy rate of 100%.

A completely free area thus has an occupancy rate of 0%.

A partially occupied area thus has an occupancy rate of between 0% and 100%, with 0% and 100% not being included.

In the percentages indicated above, the percent refers to a number of parking spaces in the area.

Thus, the phrase "at least partially substantiated" includes, in particular, the phrase "fully occupied" and the phrase "partially substantiated".

The phrase "multiple ranges" means "at least two ranges," that is, two or more ranges.

A traffic includes, for example, one or more motor vehicles and / or one or more bicycles.

3 shows a parking lot 301 for motor vehicles.

The parking lot 301 includes a bullet 303 , Inside the bullet 303 are a first area 305 , a second area 307 , a third area 309 and a fourth area 311 provided or formed.

This means, in particular, that four areas are defined or defined. The four areas 305 . 307 . 309 . 311 each include several parking spaces 313 , The projectile 303 also includes a driveway 315 and one of the driveway 315 opposite exit 317 , wherein, for example, it may be provided that the entrance 315 can also be used as an exit. The exit 317 in particular can also be used as a driveway.

Inside the bullet 303 are several barriers 319 intended. One of the barriers 319 is opposite the driveway 315 arranged. Another barrier 319 is at a driveway 321 to the third area 309 intended. Another barrier 319 is at a driveway 323 to the second area 307 intended. Another barrier 319 is at the exit 317 intended. Another barrier is at a driveway 327 to the fourth area 311 intended. Another barrier is at a driveway 325 to the first area 305 intended

Instead of or in addition to one or more or all of the barriers 319 is provided according to a further embodiment that an optical signal transmitter or a plurality of optical signal transmitters are arranged at the corresponding locations.

In a respective entrance area of the four areas 305 . 307 . 309 . 311 is each an environment sensor 329 intended. For example, several environmental sensors are provided at an entrance area or in an entrance area. The entrance area is also an exit area in this embodiment shown.

The respective environment sensor 329 detects, for example, a retraction of a motor vehicle in the corresponding area or a leaving a motor vehicle from the corresponding area. In this way, for example, the number of vehicles located within the corresponding area can be determined. Motor vehicles that drive in and out of the area, so by means of the respective environment sensor 329 counted.

In an embodiment, not shown, it is provided that the areas 305 . 307 . 309 . 311 each having an exit, on the analogous to the entrance area, an environment sensor is provided to detect departing motor vehicles and to determine based on the detection of a number of extending motor vehicles. For example, based on a determined number of vehicles entering and on a determined number of departing motor vehicles, a number of motor vehicles that are within the corresponding area are determined.

The environment sensors 329 So count the motor vehicles, which drive into the corresponding area respectively drive out of the corresponding area. In this respect, therefore, a balance sheet of the vehicles located within the corresponding area is determined. In this respect, the environment sensor 329 also be referred to as an accounting sensor.

The environment sensor 329 For example, a pressure sensor disposed within a hose is disposed on a lane of the entrance area or sunk in the lane of the entrance area.

The several parking spaces 313 each have a parking space sensor 331 on, which is represented here symbolically by means of a filled circle.

The parking space sensors 331 monitor the corresponding parking space and can determine the occupancy status of the parking space based on the monitoring.

As a result, in particular, the technical advantage is caused that the occupancy states of the parking spaces 313 are known.

The parking space sensors 331 For example, pressure sensors are located on the parking space or submerged in the parking space.

The parking space sensors 331 can also be referred to as single-user sensors, insofar as they detect an occupancy state of a single parking space.

By means of monitoring, it is thus known what occupancy level the areas 305 . 307 . 309 . 311 exhibit. If one of the areas 305 . 307 . 309 . 311 is completely free, becomes a barrier 319 closed the corresponding driveway to block the completely free area for traffic.

In the present case, it is assumed by way of example that the monitoring has revealed that the fourth area 311 completely free. Then it is envisaged that the barrier at the driveway 327 is closed. The traffic now becomes, for example, the first area 305 directed by the barrier 319 at the driveway 325 is opened and the barriers 319 at the driveways 321 . 323 , at the exit 317 and opposite the driveway 315 getting closed. The traffic can thus only to the first area 305 drive and park there.

If the first area 305 has a predetermined degree of occupancy, for example is fully occupied, the barrier becomes 319 at the driveway 325 closed. For example, the traffic now becomes the second area 307 directed. It is intended that this is the barrier 319 opposite the driveway 315 is opened. The closets 319 at the driveway 323 will be opened. The traffic can thus only to the second area 307 drive.

In areas that are completely free, here for example the fourth area 311 , electrical loads are switched off to save electrical energy.

If instead of or in addition to the barriers 319 optical signal transmitters are provided, it is provided, for example, that they emit correspondingly red light or green light. Red light to signal the traffic that he is not allowed to drive through. Green light to signal to the traffic that he is allowed to drive through.

Thus, the parking area includes 301 So several areas 305 . 307 . 309 . 311 , each with several parking spaces 313 include.

The sensors 329 . 331 are encompassed by a monitoring system not further shown here. The barriers 319 are covered by a not further shown here control system. Further, a processor not shown here is also for determining based on the monitoring of a respective occupancy state of the parking spaces of the plurality of areas 305 . 307 . 309 . 311 ,

Thus, the parking area includes 301 a system for guiding a motor vehicle to a parking space of a parking space according to the invention.

The monitoring system includes, for example, other environmental sensors, for example, within the areas 305 . 307 . 309 . 311 are arranged.

Thus, in summary, the invention provides an efficient concept for efficiently reducing electrical energy consumption of a parking space. In particular, it is provided that an instantaneous occupancy state of the parking spaces is detected. Furthermore, it is provided in particular that a guidance or guidance of motor vehicles to free parking spaces is planned, wherein the planning is carried out taking into account, for example, costs, in particular energy costs. This means that the motor vehicles are led to free parking spaces in such a way that energy consumption and thus energy costs of the parking space can be minimized or at least reduced.

A guiding of motor vehicles is carried out in particular by means of barriers or displays respectively optical signal transmitters.

A fundamental idea according to the invention can be seen, in particular, in that electrical consumers of a region which is completely free are switched off.

An electrical load is, for example, an actuator.

An electrical consumer is, for example, one of the following electrical consumers: parking space sensor, surroundings sensor, occupancy status indicator, lighting, illuminant, monitoring system.

In order to reduce the electrical energy consumption, it is thus provided, in particular, not to guide the traffic in the presence of a completely free area to this completely free area, but to an area which is partially occupied. The completely free area is thus no longer hit by motor vehicles and thus remains completely free. Thus, electrical loads in this area are no longer needed and can thus be switched off.

In particular, it is provided that the other areas, which are also partially occupied, to which the traffic is currently not directed, are also closed to traffic at least temporarily. This is particularly due to the fact that barriers or optical signalers signal the traffic that entry into these areas is prohibited or blocked.

For example, traffic is initially directed only to the one area that is partially occupied.

Only when this one area has a predetermined occupancy rate, for example 100%, is it for example provided that another of the several partially occupied areas is reopened for traffic, so that the traffic is then routed to this area.

It is therefore provided in particular that areas are completely filled with vehicles, so that they are therefore initially fully occupied in particular in order to have as many other areas completely free respectively to leave.

This is especially true when motor vehicles leave an area. For example, new vehicles driving into the parking lot are routed again in such a way that they fill areas that have already been filled, so that even previously open areas have been filled Areas can be closed again because they were completely free after leaving motor vehicles.

In closed areas, in particular, unnecessary electrical loads are switched off, for example lamps, parking sensors (parking space sensors) and monitoring systems.

As a result, in particular costs can also be saved if less or no service is required for these closed areas. Such a service includes, for example, a cleaning or a tour of a service staff.

For example, at least two regions, for example exactly two regions, for example at least four regions, are provided.

Preferably, there are guide displays or guide barriers (ie the barriers) for guiding or guiding the traffic. The terms "guiding" and "guiding" in the sense of this description can be used synonymously, for example.

For example, it is provided that the traffic is indicated by means of a display and / or a sign, where it has to go. For example, it is provided that a corresponding driving recommendation is displayed within a motor vehicle, for example by means of a navigation device.

For example, provision is made for barriers to be opened or closed in order to guide the traffic to be conducted precisely to one of the partially occupied areas.

The planning for the guidance of the motor vehicle is thus based, in particular, on parking space occupancy data, which therefore indicate, in particular, an occupancy state of a parking space or occupancy states of the parking spaces.

For example, several single-seat sensor systems (ie single-user sensors) are used to determine the parking space allocation data. Single-seat sensor means here in particular that per parking space a parking space sensor is provided for monitoring the parking space.

Preferably energy self-sufficient floor sensors are used. A floor sensor is, for example, a parking space sensor, which is arranged sunk in accordance with this embodiment on the ground, ie on the parking space surface respectively on the road or in the parking space respectively in the roadway. Such a floor sensor is for example one of the pressure sensors described above.

According to one embodiment, accounting sensors are used instead of or in addition to the single-user sensor systems. These balancing sensors are arranged, for example, at an entrance or at an exit of an area and thus advantageously include motor vehicles that enter or exit the area.

In one embodiment, additional environmental sensors are used for monitoring: for example, motion and / or presence sensors. The corresponding monitoring data of these further environmental sensors are then integrated, for example, into a planning and implementation for the routing of the traffic to be conducted.

According to one embodiment, the customer behavior or the customer's request is included in a planning. For example, it is provided that in the case of a plurality of completely free areas, that free area is selected which is to be opened next for traffic, that is, to which the traffic is to be routed next, whose distance to an entrance door or exit door of the parking space is minimal.

Advantages of the invention are, in particular, savings in costs, in particular energy costs, by switching off electrical consumers, in particular lamps or lamps.

Advantages of the present invention are, in particular, savings in costs by switching off parking reservation displays which, for example, can emit red or green light depending on an occupancy state.
