Abstract

One aspect of the invention relates to a method for optimizing the parking space of a parking strip which can be parked in the longitudinal direction with a plurality of motor vehicles. Between two specific vehicles there is a longer gap compared to the remaining gaps. This longer gap comprises a buffer space which, unlike the longer gap, does not have the shorter gaps. However, it is also conceivable that the longer gap lies between the foremost vehicle and an optionally existing front boundary or the rearmost vehicle and an optionally existing rear boundary. For parking a Ausparkwilligen vehicle, which does not border on the longer parking space, the one or more vehicle automatically sat down without human driver such that the buffer space is closed and is relocated to the parking willing vehicle, so that the displaced buffer space the ausparkwilligen vehicle for Off-road parking is available.

Description

The invention relates to a method for parking space optimization of a parkable with several motor vehicles, especially cars, parking strip in the longitudinal direction.

When parked in the longitudinal direction parking strips of the existing parking space is generally not optimally used. Frequently, the distances between the vehicles parked in a row are unnecessarily large, so that fewer vehicles can park on the parking strip than would be possible at optimal distances.

From the publication DE 10 2013 221 274 A1 It is known that a signal from a parked vehicle is sent to an already parked vehicle, which then automatically advanced or reset without human driver, so that a sufficiently large gap for the parking vehicle is available. The method may also be extended to a plurality of parked vehicles such that a portion of the vehicles move forward and a portion of the vehicles move rearward to increase the parking space.

In the publication DE 10 2009 057 647 A1 it is similarly known that parked vehicles are prompted by a parking vehicle to increase the parking space by autonomous resetting. For parking an already parked vehicle, the parked vehicle may prompt the neighboring vehicles to move forwards or backwards, so that more space is available for parking.

The publication DE 10 2012 024 151 A1 describes that a signal is sent to a parked motor vehicle and the parked vehicle is moved in response to the signal, so that the parking space is increased and the parking of a motor vehicle to be parked is made possible.

In the method for parking space optimization from the document DE 10 2012 215 218 A1 It is determined whether within a given parking area an additional parking space can be provided by changing the position of parked vehicles, in response to which the parked vehicles are moved remotely.

It is an object of the invention to provide a method for parking space optimization of a parking strip, which is characterized by an improved utilization of the parking space.

The object is solved by the features of the independent claim. Advantageous embodiments are described in the dependent claims. It should be noted that additional features of a claim dependent on the independent claim without the features of the independent claim or only in combination with a subset of the features of the independent claim may form a separate invention independent of the combination of all features of the independent claim, the subject of an independent claim, a divisional application or a subsequent application. This applies equally to technical teachings described in the specification, which may form an independent invention of the features of the independent claims. For example, this applies to the described idea that a vehicle from outside the vehicle can be requested by a person on the vehicle to implement.

One aspect of the invention relates to a method for optimizing the parking space of a parking strip which can be parked in the longitudinal direction with a plurality of motor vehicles. Several motor vehicles park on the parking strip. Preferably, all parked vehicles are set up to be able to automatically reset and reset without human driver.

There are gaps between the neighboring vehicles. Between two specific vehicles there is a longer gap compared to the remaining gaps between the vehicles. It is preferably only a single longer gap available. This longer gap comprises a buffer space which, unlike the longer gap, does not have the shorter gaps. The longer gap with the buffer space is preferably so long that it allows a Ausparken when a vehicle adjacent thereto. The shorter gaps are preferably as short as possible, and for example have a length in the range of 0.02 m to 0.20 m. Compared to the longer gap, the remaining, shorter gaps are preferably so short that a vehicle adjacent to two shorter gaps can not park out (collision-free). The shorter gaps are preferably substantially the same length. For example, the shorter gaps are only 0.1 m long and the longer parking space with buffer space is for example 1.0 m long. However, it is also conceivable that the longer gap lies between the foremost vehicle and an optionally existing front boundary or the rearmost vehicle and an optionally present rear boundary of the parking strip.

To park a ausparkwilligen vehicle, which does not border on the longer parking space, sat one or more vehicle automated to such a way that the buffer space is closed and to ausparkwilligen Vehicle is relocated, so that the displaced buffer space the ausparkigenigen vehicle for parking is available. The one or more vehicles thus move away from the parking-ready vehicle to close the buffer space. For example, the one or more vehicles reset automatically when the longer parking space with the buffer space lies behind the parking-ready vehicle before the transfer takes place. Instead, set the one or more vehicles, for example, automated, if the time before the implementation of the longer parking space with the buffer space in front of the parking lot willing vehicle.

These vehicles can thus be implemented automatically without human driver. Preferably, the conversion takes place completely autonomously. For example, in a parked vehicle with no significant gaps to the vehicle parked in front of it and the vehicle parked behind it, a message may be sent to surrounding vehicles to fully autonomously close and deploy the buffer zone so that the buffer zone shifts to the parked vehicle becomes. Alternatively, however, it may also be provided that a parked vehicle is awakened directly by the driver via built-in sensors by the driver, for example by laying on hands or by holding an NFC token (NFC - Near Field Communication), and then moves automatically when the hand is applied, for example; the vehicle is thus moved by the driver.

In principle, in the method, the gaps between the vehicles can be so small that the vehicles can not easily park out; the parking space of the parking strip can be optimally utilized. However, by providing a longer gap with a buffer space that can be relocated to the parking-ready vehicle, it can be ensured that the parking-willing vehicle can be parked. After the ausparkwillige vehicle has been parked, automatically results in the location of the parked vehicle, a gap that has the maximum possible length. This allows a parking willing vehicle very easily parked in this gap.

The invention is based on the following finding: Often the sum of the parking spaces on a parking stiffener results in a gap that is large enough to allow at least one additional vehicle to park there. In order to optimize the parking space, the vehicles can be arranged for example by means of automated maneuvering with only a very small distance close to each other. This tight arrangement of the vehicles one behind the other with a small distance between the vehicles is possible, if in addition a buffer space is available, which is sufficient for parking a vehicle, and which can be moved by re-parking respectively ausparkwilligen vehicle.

It would be conceivable that, in the case of a plurality of vehicles located between the buffer space and the parking-ready vehicle, they move almost simultaneously from the parking-ready vehicle to relocate the buffer space to the parking-willing vehicle. These vehicles could move up as being substantially simultaneous. However, it is advantageous if the plurality of parking vehicles, which are located between the buffer space and the ausparkwilligen vehicle, successively move up such that the buffer space is moved to the ausparkwilligen vehicle.

It can be provided that the one or more parking vehicles, which are located between the longer parking space and the parking-willing vehicle, each receive a message to implement the vehicle and implement in response to this automated. For example, the message may be sent from the out-of-the-box vehicle to a vehicle to be transposed or sent by a stationary backend system (after the parked vehicle, for example, has sent an umpark request to the backend system).

Communication with the parked vehicles can also be dispensed with if a parked vehicle is being woken up via built-in sensors by the driver of another vehicle (in this case the parking vehicle), for example by laying on hands from outside, and then by the person from outside (making use of the vehicle drive). can be moved, so to speak.

In general, it can therefore be provided that a vehicle which is located between a buffer space comprising the longer parking space and the ausparkwilligen vehicle and adjacent to this longer parking space, using a vehicle-mounted sensors detects that this from outside the vehicle from a person on the vehicle Reactivation is requested. In response to this determination of a request for conversion, the vehicle then moves away from the out-of-vehicle vehicle and thus moves on.

For example, by means of an on-board sensor system, a persistent action (eg touching the vehicle) of the person directed at the vehicle's transposition is detected, the vehicle moving away from the vehicle for the duration of the action. For example, the vehicle automatically moves as long as the person moves it Vehicle touched. If the moving vehicle comes too close to the neighboring vehicle (for example, the distance becomes smaller than a threshold value), the vehicle movement preferably stops automatically. It is advantageous if, prior to the movement of the vehicle, an identification of the person takes place (for example via an NFC token carried by the person or an evaluation of the fingerprint) and the transfer of the vehicle is permitted only after the result of the identification.

However, it can also be provided that a parked vehicle, which must be implemented for parking out the parked vehicle, after an action of the person on the parked vehicle (eg closes, for example, without the person having to continue to touch the vehicle to be converted during the transfer.

It would also be conceivable that the driver of the ausparkwilligen vehicle from his own vehicle out (virtually virtual) can implement / move a vehicle via an actuated control element, for example via a button to be operated. It would be conceivable for the driver to shift an illustrated vehicle with one movement (eg wiping movement) on a screen in one's own vehicle without having to leave the vehicle. It would therefore be conceivable that the driver of the ausparkwilligen vehicle via actuation of a control element in the ausparkwilligen vehicle causes a conversion of the vehicle, which is located between the longer parking space and the ausparkwilligen vehicle and adjacent to the longer parking space.

It has been described above that a vehicle to be converted can be shifted from outside the vehicle. This idea can also be used independently of the features of claim 1.

A further aspect of the invention therefore relates to a method for converting a parked vehicle and a correspondingly equipped vehicle, which detects, by means of a vehicle-mounted sensor system, that this is requested to be moved from outside the vehicle by a person on the vehicle, and in response thereto the vehicle converts. For example, the parked vehicle is awakened by triggering a built-in sensors in the vehicle and then moved by automated driving.

As already described above, for example, by means of a vehicle-side sensor system, a persistent action (eg touching the vehicle) of the person directed towards the vehicle being moved is determined, with the vehicle moving for the duration of the action. For example, the vehicle automatically moves as long as the person touches the vehicle to be moved. If the moving vehicle comes too close to an obstacle (for example, the distance becomes smaller than a threshold value), the vehicle movement preferably stops automatically. It is advantageous if, prior to the movement of the vehicle, an identification of the person takes place (for example via an NFC token carried by the person or an evaluation of the fingerprint) and the transfer of the vehicle is permitted only after the result of the identification.

However, it may also be provided that a parked vehicle, which must be implemented for parking the vehicle out of the park, automatically fills a gap in the vehicle after an action by the person on the parked vehicle (for example, by applying an NFC token to the vehicle to be converted) Essentially completely closes, for example, without the person must continue to touch the vehicle to be converted during the implementation.

A further aspect of the invention relates to a method for converting a parked first vehicle, in which the driver of a second vehicle (for example, a parking or parking vehicle) via actuation of a control element in the second vehicle causes a conversion of the first vehicle. The driver of the second vehicle can thus move out of his own vehicle (virtual, so to speak) a vehicle via an actuated operating element. It would be conceivable for the driver to be able to move one or more vehicles represented on a touch-sensitive screen in his own vehicle with a touch gesture (for example a swipe motion) without having to leave the vehicle.

In a further aspect of the invention, the individual vehicles parked on the parking lane measure the gaps measured by the on-board distance sensors in front of and / or behind the respective vehicle (if suitable distance sensors are present) and report using C2C communication (vehicle-to-vehicle). Vehicle communication) or C2I communication (vehicle-to-infrastructure communication), the distances determined by the vehicle's distance sensors in front of or behind the vehicle on.

An infrastructure or vehicle itself can then determine whether by reducing the distance between the already parked vehicles enough Space for another vehicle can be created. If so, the already parked vehicles automatically drive together so far that the new vehicle can park. This can be driven so far that in a complete parking bay, only so much space between all parked vehicles is available that just a single vehicle can switch on or off by moving.

The invention will be described below with reference to an embodiment with the aid of the accompanying drawings. In these show:

1a - 1d an exemplary Ausparkituation using the method according to the invention;

2 an exemplary flowchart of an embodiment of the method according to the invention; and

3 Exemplary parking situations when considering conventional vehicles.

In 1a - 1d is an exemplary Ausparkituation for a ausparkwilliges vehicle 2 represented using the method according to the invention. 1a shows the Ausparkituation before the start of the Ausparkvorgangs. The passenger cars 1 - 5 are on one side of a road 7 arranged park strips 6 parked in the longitudinal direction. The parking area is optimally utilized: the vehicles are parked with as little distance as possible. Only between two vehicles (here the vehicles 4 and 5 ) there is a longer gap 13 ; the remaining gaps 10 . 11 . 12 between the vehicles are significantly shorter than the longer gap 11 , The shorter gaps 10 . 11 . 12 are so short that the vehicles 2 . 3 not ausparkbar are. Preferably, the shorter gaps 10 . 11 . 12 essentially the same length. For example, the length of these gaps is l ₁ = 0.1 m. Also the gaps 14 and 15 between the foremost vehicle 1 or the rearmost vehicle 5 to the front or rear boundary of the parking strip are similarly short; the vehicle 1 is therefore not ausparkbar (the vehicle 5 would be because of the longer gap lying ahead 13 ausparkbar).

The longer gap 13 includes an extra buffer space and is so long that, for example, that to the gap 13 adjacent vehicle 5 (or 4 ) is collapsible without collision. The longer gap is, for example, l ₂ = 1.0 m long. The buffer space should be sized so that it is sufficient to park for the longest vehicle that supports this procedure.

All parked vehicles 1 - 5 on the parking strip 6 are set up to automatically reset and reset without human driver. It can be provided, for example, that on the parking strip 6 only allowed to park such vehicles set up. All of these vehicles are also configured to park in accordance with the procedure described below.

The following is assumed to be the driver of the vehicle 2 want to park. The parking of the vehicle 2 is carried out automatically. The Ausparkprozess is, for example, by pressing an operating element on the part of the driver of the ausparkwilligen vehicle 2 started. The procedure of the Ausparkprozesses is based on the exemplary flowchart in 2 explained. It is assumed that the order of vehicles and the position of the buffer space the vehicle 2 is known by previous data exchange with the other vehicles.

After starting the Ausparkprozesses sends the ausparkwillige vehicle 2 a message for transferring to the vehicle, which is located between the buffer space and the ausparkwilligen vehicle 2 is adjacent to the buffer space (see step 100 in 2 ). This is the vehicle 4 , This vehicle 4 receives the message and, in response, handles the buffer space behind the vehicle 4 is closed (see step 110 in 2 ). This is what the vehicle is about 4 automated back to just a small gap with the length l ₁ between the vehicle 4 and the vehicle 5 remains. After completion of the conversion and closing of the buffer space, the vehicle sends 4 a message about this (see step 120 ). In 1b is the situation after moving the vehicle 4 shown. The buffer space became the gap 12 between the vehicles 3 and 4 postponed. It will be after moving the vehicle 4 on the part of the vehicle wanting to park 2 Checked if the ausparkwillige vehicle 2 adjacent to the buffer space (see query 130 in 2 ). If this is not the case, the vehicle adjacent to the buffer space is requested to reset and close the buffer space, as previously explained. In this case, the vehicle sets 3 back and closes the buffer space between the vehicle 3 and the vehicle 4 , with only a small gap of length l ₁ between these vehicles 3 . 4 remains.

If repeated passage of the step 140 Finally, it is determined that the ausparkwillige vehicle adjacent to the shifted buffer space, the ausparkwillige vehicle 2 ausparken. This situation is in 1c shown. For the Ausparkvorgang the length l ₁ + l ₂ are available. The vehicle 2 resets into the buffer space and then parks forward out of the parking space. The Resetting the vehicle 2 and the parking of the vehicle 2 be automated. A reset is not required if the moved buffer space is in front of the vehicle 2 located.

Since the Ausparkpuffer has been moved to the ausparkende vehicle and apart from the ausparkende by the vehicle 4 If there is a gap in the parked vehicles as close as possible to one another, it remains after the vehicle has been parked 2 a maximum parking space to allow the next vehicle easy parking. In 1d is the situation after parking the vehicle 2 shown.

A parking willing vehicle 8th can then park with automated lateral and longitudinal guidance in this parking space backwards. In the park end position then points the vehicle just parked 8th the greatest possible distance to the rear vehicle 3 and the smallest possible distance to the front vehicle 1 or vice versa. The buffer space is after parking so in front of or behind the just-parked vehicle 8th , Provided the just parked vehicle 8th a greater length (shorter length) than the vehicle 2 The buffer space is then shorter (longer) by this length difference than before the vehicle has been parked 2 ,

In a simple approach, the buffer space is always behind or always in front of a just-parked vehicle.

In an advanced approach, before concluding the parking maneuver, it is decided, depending on one or more decision criteria, whether the buffer space is in front of or behind the vehicle that has just been parked 8th should be located (ie whether the parking vehicle 8th as far as possible at the end of the parking process or as far as possible). This serves the purpose of having to move the buffer space later as few times as possible if another vehicle from the parking strip 6 want to park.

As a decision criterion, for example, the number N _behind the vehicles that are behind the gap used for parking and the number N in _{front of} the vehicles that are in front of the gap used for parking, are used. For example, if the number N is _{behind before>} N, the vehicle is 8th parked so that after parking the buffer space in front of the just-parked vehicle 8th located. Conversely, if the number N is _{behind before} <N, the vehicle is 8th parked so that after parking the buffer space behind the just-parked vehicle 8th located.

As a decision criterion, information about the Ausparkwahrscheinlichkeit the other vehicles in the park strip 6 be used, for example, information about the maximum parking time of the individual vehicles. For example, when it is known that the parking time of a certain vehicle is next, for example, the buffer space becomes behind the parking vehicle 8th placed when that particular vehicle is behind the gap used for parking. If this particular vehicle is in front of the gap used for parking, the buffer space becomes in front of the parking vehicle 8th placed.

It has been described above that the vehicles were each requested to implement a received message. Communication with the vehicles could also be dispensed with if a vehicle to be converted in each case via a sensor installed in the vehicle to be converted from outside the vehicle to be converted is woken up by the driver of the parked vehicle and can then be displaced on command of the driver. In this case, the driver of the ausparkwilligen vehicle is preferably directly to the vehicle to be converted. It would also be conceivable that the driver of the Ausparkwilligen vehicle from his own vehicle out (virtual, so to speak) can move a vehicle via an actuated control element, for example via a button to be pressed. It is conceivable that the driver on a screen in his own vehicle, the vehicles shown in each case with a movement (eg wiping movement) moves without having to leave the vehicle.

In the example of 1 and 2 it was assumed that all parked vehicles 1 - 5 on the parking strip 6 support the method of the invention and are set up without being able to automatically reset and reset human driver. If individual vehicles on the parking strip are not able to do so, this should be taken into account accordingly. Such vehicles are referred to below as conventional vehicles. If a conventional vehicle interrupts a chain of non-conventional vehicles, a respective buffer zone in the row in front of the conventional vehicle, in particular directly in front of the conventional vehicle, and a buffer zone in the row behind the conventional vehicle, in particular directly behind the conventional vehicle, can be provided become.

For example, the buffer space after parking a vehicle can always be moved so that this is a conventional Vehicle adjoins. Thus, the conventional vehicle always has the opportunity to be able to park without using the method according to the invention. If another non-conventional vehicle adjacent to the buffer space wishes to park, the buffer space may be moved to the out-of-the-box vehicle by automated transfer, as described above. In 3 is a parking situation with a single conventional vehicle 20 shown, for the reasons described above both before and behind the conventional vehicle 20 in each case a buffer space is provided. Unless the conventional vehicle 20 the foremost vehicle or the rearmost vehicle of the series of vehicles becomes a buffer space behind the conventional vehicle 20 or provided in front of the foremost vehicle.

As an alternative to placing the buffer space in front of and / or behind the conventional vehicle, it would also be possible to maintain a certain safety distance from a conventional vehicle so that the conventional vehicle can always park out (for example in front of and behind the vehicle 20 in 3 ). The buffer space can then be located somewhere in the vehicle row.

However, if a buffer space is placed in front of or behind a conventional vehicle, there is the risk that the driver of the conventional vehicle partially or completely closes the buffer space by reacting and thus there is insufficient buffer space available for the method described above. Remedy is an additional buffer space between the non-conventional vehicles, care being taken during the parking, that the buffer space is moved only between the non-conventional vehicles. In 4 such a parking situation is shown. At the vehicles 30 . 31 are conventional vehicles. Behind the conventional vehicle 30 a buffer space or a safety distance is provided so that the vehicle 30 can park without problems. In front of the conventional vehicle 31 In addition, a buffer space or a safety distance is provided, so that the vehicle 31 can park without problems. Between the non-conventional vehicles, a separate buffer space is kept, in the case of 4 between the non-conventional vehicles 32 and 33 , This own buffer space can be shifted between the non-conventional vehicles for parking a particular vehicle, but this should always remain between the non-conventional vehicles.
