Description

Technical area:

The present invention relates to a method and a device for detecting incorrect occupancy of a, in particular public, parking lot with a charging station for electrically charging a vehicle, in particular a (hybrid electric / electric) vehicle or an electric bicycle.

State of the art and object of the invention:

Currently (public) parking spaces (parking facilities) with charging stations (charging facilities) for the electrical charging of vehicles, especially hybrid electric / electric vehicles or electric bicycles are still very limited and manageable, so that a correct use of this parking still exists and a misuse of these parking lots not frequent occurs.

In the future, the expansion of parking spaces with charging stations is planned. With the increase in parking spaces with charging stations, however, the "danger" of a "false occupancy" increases that the parking lots with charging stations not only by vehicle users (ie drivers or owners of the vehicles) are used, which also actively use the charging option.

In other words, the parking spaces with charging stations can increasingly be occupied by vehicle users who consciously or unconsciously do not carry out the electrical charging and thus would use the parking spaces, which are primarily intended for the electrical charging of the vehicles, wrongly. For example. Vehicle users of pure combustion vehicles or hybrid electric / electric vehicles can park their vehicles in the parking lots with charging stations without initiating a charging process.

However, such a development is not in the sense of infrastructure or parking lot operators, because then the costly infrastructure or parking can not be fully utilized, or have temporal training phases.

From the US 2014/0167985 A1 a system for managing a parking space for a vehicle for a room, comprising means for detecting whether the room is occupied, and at least one charger which is suitable for automatic loading, in particular for automatic loading after manual correction.

From the HK 1217604 A2 a parking space monitoring system for electric vehicles is known, comprising a main unit for each parking lot, a router, which is housed in the main unit and connected to a network. At least one digital camera is arranged in a position to take digital pictures of a parking lot.

From the DE 10 2015 204 366 A1 a system for the release control of a parking lot for a motor vehicle is known. It comprises an electric charging device mounted in the area of the parking space for a motor vehicle with an electric driving energy storage, a device for determining whether the charging system is in operation, and a processing device for releasing the parking space for use by a motor vehicle with electric driving energy storage, if the charging system not connected to a motor vehicle.

From the KR 10 1691559 B1 or its English translation, a system and method for remotely monitoring a charging infrastructure of an electric vehicle to unnoticed operate and effectively manage a charging infrastructure of an EV station known.

The object of the invention is therefore to provide a possibility with which a misuse of parking spaces with charging stations can be effectively prevented.

Description of the invention:

This object is solved by subject matters of the independent claims. Advantageous embodiments are the subject of the dependent claims.

According to a first aspect of the invention, a method for detecting incorrect occupancy of a, in particular public, parking space (ie a parking space) with a charging station (a charging facility) for electrically charging a vehicle, in particular a (hybrid electric / electric) vehicle or provided an electric bicycle.

According to the method, it is detected (or determined) whether the parking space is occupied by the vehicle. Upon detection of the occupancy, the charging status of the vehicle is determined. If a missing charging process or a pseudo-charging process is detected by determining the charging status, a warning signal is emitted.

A parking space with a charging station is a parking space that is primarily intended for the electrical charging of a vehicle and not for the pure parking of the vehicle.

The detection or determination of the occupancy of the parking lot is performed, for example, by the charging station. Alternatively, the detection or the determination but also by the vehicle be carried out and then the charging station, for example, be communicated via a wireless (or wireless) message transmission.

By (automatically) determining the charging status of the vehicle is easily and reliably detected whether the parking lot is missing. In the case of a failed unsuccessful determination of the charging status of the vehicle, it is also assumed that the parking space was incorrectly allocated.

The term "faulty occupancy" is understood here as an occupancy of a parking lot, which is primarily intended for the electrical charging of vehicles, but the charging function of the parking lot is not used at all (lack of charging) or only to an insufficient extent (pseudo-charging) ,

The term "pseudo-charging" means that a charging process is initiated, although this would not have been necessary at all, or this would be done only with a very low charging power, with which a rapid charging is not possible. With a "pseudo-charging" is thus the parking lot with the charging function, which is primarily intended for charging, not used in the intended context or insufficiently.

Esp. In the case of a parking lot with an inductive charging station, where a "correct" charging operation is difficult to recognize from a "outside" manual visual inspection, it is easy and reliable to ascertain a faulty occupancy by determining the charging status mentioned above.

By issuing a warning signal, a "conscious or unconscious" misuse of the parking space struck vehicle users or other involved persons or even automated systems for managing the parking lot can be communicated in a simple manner so that they (persons, including the vehicle users, or systems) can take appropriate action , such as B. driving away the vehicle from the parking lot or initiating a "proper" charging.

With the described method it can be ensured that the parking spaces with charging stations are not occupied by vehicles without the charging function of the parking spaces being used in the intended context. This does not only apply to electrically non-rechargeable vehicles, such as: As vehicles with only a purely internal combustion engine drive, but also for electrically rechargeable vehicles such. B. hybrid electric vehicles, which do not use the parking or insufficiently in the intended frame, so do not use for loading but only for parking.

This provides a possibility with which a misuse of parking spaces with charging stations can be effectively prevented.

The steps: recognizing the occupancy and determining the charging status, autonomous and esp. Can be done without a manual or automatic intervention of a central, if necessary, also networked control system.

For example. the occupancy of the parking space is detected (by the vehicle) by means of a pressure-sensitive sensor (pressure sensor mat), a photosensitive sensor (photocell), or a camera.

As a pressure-sensitive sensor, for example, a pressure sensor mat can be used, which is placed on the parking lot floor or embedded in the parking lot floor and is adapted to detect by measuring the pressure values acting on the pressure sensor mat or their change in value, whether a vehicle is parked in the parking lot ,

As a photosensitive sensor, a photointerrupter installed at the parking lot and arranged to detect, based on an interruption of, for example, a light beam (possibly reflected) emitted therefrom, whether a vehicle is parked in the parking lot.

A lack of charging of parked in the parking lot vehicle is detected, for example. By detecting that the vehicle is not electrically connected to the charging station of the parking lot (in the case of a wired charging) or no charging current from the charging station flows to the vehicle (im Case of inductive charging).

A pseudo-charging operation of the vehicle parked in the parking space is detected, for example, when it is determined that the charging power of the charging station of the parking lot for electrically charging the vehicle is below a predetermined minimum desired charging power.

For example. the pseudo-charging process is further detected when it is determined that the state of charge of the vehicle at the start time of charging at a predetermined state of charge value of, for example. Over 80%, esp. Over 90%, especially over 95%.

Alternatively or additionally, the pseudo-charging process is, for example, further detected when it is determined that the state of charge of the vehicle via a given time duration at the given state of charge value of, for example, more than 80%, esp. Over 90%, especially over 95%, remains.

For example. the charging status of the vehicle is repeatedly determined at predetermined intervals. In this case, the warning signal, for example, even delivered when the missing charge or the pseudo-charging over a predetermined period of more than 5 minutes, esp. Over 30 minutes, especially over an hour, is detected.

For example. the warning signal is emitted in the form of an optical and / or an acoustic signal. Esp. the warning signal is emitted at or near the car park.

Thus, vehicle users can be informed before or when leaving the vehicles that a "proper" charging was not initiated.

For example. the warning signal is delivered via a wired or wireless message transmission to a message receiving device, for example, the vehicle user. Esp. the warning signal is emitted in the form of a telephone call or a radio message to a, in particular mobile, telephone / radio-message receiving device.

In this case, the telephone / wireless message receiving device may be a device of the user of the vehicle. This can also be used to inform vehicle users who are not in the immediate vicinity of the vehicles. Alternatively or additionally, the telephone / radio message receiving device may be a device from a private or public car park management office, in particular a public traffic control for the prosecution of parking violations.

For example. the warning signal is given to a, especially fully automatic, parking management system. Here, the parking lot management system may be a system of the aforementioned private or public car park management office.

For example. An identification feature of the vehicle can also be detected. The detected identification feature can then be delivered with the warning signal to the parking lot management system. Thus, the vehicle and thus also its users can later be clearly identified, for example. In the case when z. B. a reminder or a fine for the wrong occupancy of the parking lot should be issued.

By way of example, the vehicle registration number of the vehicle can be detected as the identification feature, for example by a photograph of the vehicle registration number by means of a camera installed in the parking space.

For example. it is further determined whether the vehicle is locked. In this case, the warning signal is issued only when it is determined that the vehicle is locked.

This avoids vehicle users who are, for example, being in the process of initializing a charging process, such as eg. B. by plugging a charging cable to the charging station to be premature warning.

According to a further aspect of the invention, a device is provided for detecting incorrect occupancy of, in particular, public, parking space with a charging station for electrically charging a vehicle, in particular a hybrid electric / electric vehicle or an electric bicycle.

The device comprises a recognition arrangement which is set up to detect or determine whether the parking space is occupied by the vehicle. The device further comprises a charging control arrangement for controlling and / or regulating the charging station for electrically charging the vehicle. In addition, the device comprises a warning arrangement for emitting a warning signal.

In this case, the recognition arrangement is further set up to give an occupancy signal to the charging control arrangement when recognizing the occupancy of the parking space.

The charging control arrangement is further configured to receive the occupancy signal from the detection arrangement and to determine the charging status of the vehicle upon receipt of the occupancy signal. In the event that the determined charge status indicates a missing charge or a dummy charge, the charge controller issues a charge status alert to the alert device.

The warning arrangement is further configured to receive the charging status warning signal from the charging control unit and to output the warning signal upon receipt of the charging status warning signal.

Advantageous embodiments of the method described above are, as far as possible, transferable to the above-mentioned device, to be regarded as advantageous embodiments of the device.

• 1 in a schematic representation of an apparatus according to an embodiment of the invention;
• 2 in a schematic flow diagram, a method according to an embodiment of the invention.

Detailed description of the drawings:

1 shows a schematic representation of a public parking lot PP with a charging station LS for electrically charging hybrid electric / electric vehicles and a device V for detecting incorrect occupancy of the parking lot PP ,

The charging station LS includes a pressure sensor mat DS known type, which in the bottom of the parking lot PP is admitted and is set up by measuring on this applied pressure force or their change detect whether a vehicle FZ In the parking lot PP is turned off. The charging station LS further comprises a transmitting coil SP known type for inductive charging of hybrid electric / electric vehicles. In addition, the charging station includes LS a charging control arrangement SA for controlling and regulating the inductive charging of the transmitting coil SP , The charging control arrangement SA is also part of the aforementioned device V ,

The device V is formed, for example, in the form of an electronic unit and in the charging station LS integrated. The device V includes a recognition arrangement KA to recognize an occupancy of the parking lot PP through vehicles. The device V further comprises the aforementioned charge control arrangement SA , In addition, the device includes V a warning arrangement WA to deliver a warning signal.

The recognition arrangement KA includes, for example, a light barrier, which recognizes in a manner known to those skilled by emitting a light beam and detecting a light reflection, whether the parking lot PP from a vehicle FZ is occupied.

The recognition arrangement KA further comprises a signal output unit, which is set up when recognizing the occupancy of the parking lot PP generate an occupancy signal and to the charging control arrangement SA leave.

The charging control arrangement SA includes a signal receiving unit and is about this with the recognition arrangement KA or their signal output unit connected by signal technology.

The charging control arrangement SA Further comprises a charging status determination unit which is arranged, in a manner known to those skilled in a charging status of the vehicle FZ to determine whether the vehicle FZ for charging its power storage device via a vehicle-side inductive receiving unit for inductive energy transmission with the parking-side transmitting unit SP is electromagnetically coupled, or whether a charging current with a predetermined charging power from the charging station LS to the vehicle FZ flows.

The charging control arrangement SA Further comprises a signal output unit and is further configured, in the case that the charging status determined by the charging status determination unit shows a missing charging or a pseudo-charging operation (which means that the parking lot PP is misplaced), via the signal output unit, a charging status warning signal to the warning device WA leave.

A missing charge is detected when an inductive energy transfer from the charging station LS to the vehicle FZ not taking place.

A pseudo-charging is determined when the inductive charging power from the charging station LS to the vehicle FZ is below a predetermined minimum target charging power, which is a rapid charging of the vehicle FZ ensures.

The warning arrangement WA in turn comprises a signal receiving unit and is further configured to receive the charging status warning signal from the charging control arrangement SA or its signal output unit and to issue a warning signal upon receipt of the charging status warning signal.

The warning signal includes, for example, an optical, an acoustic signal or a comparable signal, which is directly from the warning arrangement WA is given and by a person near the parking lot PP is perceptible. Thus, the warning signal indicates that the charging process is not started or already completed, or that a pseudo-charging process is present. In this case, the warning signal can be given immediately after receiving the charge status warning signal to keep it still in the vicinity of the vehicle FF user (driver or holder) of the vehicle FZ to inform in time of this condition.

The warning signal may further include a telephone call and / or a wireless message, which / which, for example. Via a mobile network to a mobile telephone / wireless message receiving device such. As a smartphone, the user of the vehicle FZ is discharged, so that this, for example, in good time from the completed charging of the vehicle FZ is informed. The vehicle user can then do that vehicle FZ in time from the parking lot PP drive away and thus release this for other vehicles for electrical charging. In this case, the warning signal can be given off for a short time, for example, 5 minutes after the receipt of the charging status warning signal, in order to make the vehicle user aware of this condition (the incorrect assignment) in a timely manner.

The warning signal may further comprise another radio message, which is transmitted via a wired or wireless communication network to a spatially from the parking lot PP remote automated parking management system (for example, a public traffic control to punish parking violations) is sent. The parking management system can then automatically issue the vehicle user a reminder or a fine for the incorrect occupancy of the parking lot PP. In this case, the warning signal can be given, for example, 30 minutes after receipt of the charging status warning signal, so that the vehicle user still has sufficient time, the vehicle FZ from the parking lot PP drive away.

For this purpose, the device comprises V furthermore a camera KM , which is set up, the vehicle registration number of the vehicle FZ to photograph and the photo-taking in a manner known to those skilled in the warning arrangement WA forward.

The warning arrangement WA is then set up to deliver the photo including the radio message to the parking management system, so that the vehicle FZ can also be clearly identified.

The device V further comprises a communication arrangement XA (a type of infrastructure vehicle communication) over which the device V among other things, a state of charge of the vehicle-side power storage and a locking state (whether the vehicle FZ locked or not). The communication arrangement XA is signal output side with the charging control arrangement SA connected by signal technology and is also set up, the determined state of charge and locking state of the vehicle FZ to the charging control arrangement SA forward.

After that the device V for detecting incorrect occupancy of the parking lot PP based on 1 has been described in detail, a corresponding method for detecting incorrect allocation based on 2 described in more detail.

Becomes a vehicle FZ In the parking lot PP turned off, so this is according to a process step S100 from the recognition arrangement KA using the pressure sensor mat DS recognized.

Will the vehicle FZ In the parking lot PP recognized, it is according to a further process step S200 the charging status of the vehicle FZ determined.

This is done according to a sub-step S210 determines or checks whether a charging process, ie a process for electrically charging the vehicle FZ at the corresponding charging station LS , initiated and also released.

If this is not the case, then according to a further method step S400 Check if the vehicle FZ is locked.

Is the vehicle FZ locked, then becomes according to another step S300 the visual and audible warning signal is issued, causing the vehicle user, the vehicle FZ leaves and thus near the parking lot PP is informed in time of the missing charge.

If a successful initiation or a successful release is determined, then in a further sub-step S220 determines or checks whether the state of charge of the vehicle FZ or its current memory (which is to be charged) at the start time of the charging process is over 90%.

If this is the case, it is assumed that the type of "pseudo-charging" is incorrect, because with a charging state of more than 90%, the need for charging the vehicle FZ usually very low.

If this is the case and according to the step S400 determines that the vehicle FZ is locked, then according to the step S300 the visual and audible warning signal is issued, causing the user of the vehicle, which is still near the parking lot PP, to be made aware in good time of the "pseudo-charging process".

If a charging process with a sufficiently high charging power is determined, then in a further sub-step S230 determines or checks whether the initiated or released charging power of the charging station LS below a predetermined minimum target charging power, for example. Less than 10% of the target charging power is. If this is the case, then a misregistration of the type "pseudo-charging", a faulty charging process or a successfully completed charging process is detected.

If this is the case, then the warning signal according to the step S300 issued in the form of an automatic telephone call or a radio message (such as SMS, Short Message Service) to a mobile phone of the vehicle user, whereby the vehicle user, who is located away from the parking PP, from the "pseudo-charging", informed of the faulty or successfully completed charging process.

The sub-step S230 is repeatedly carried out at predetermined time intervals of, for example, one minute, so that the charging process is monitored almost continuously.

Preferably, another sub-step S240 in which it is checked how long the state of the according to the sub-step S230 detected "pseudo-charging", the faulty or successfully completed charging is present.

If this condition is, for example, over five minutes before and according to the step S400 determines that the vehicle FZ is still locked, the warning signal according to the step S300 issued in the form of the telephone call or the radio message, whereby the vehicle user, who is located away from the parking lot PP, repeatedly informed of and explicitly requested by the "pseudo-charging", the faulty or the successfully completed charging, the vehicle FZ of the Parking PP to drive away.

If this does not happen and the state of the "pseudo-charging", the faulty or successfully completed charging according to the step S400 For example, for more than half an hour, then the warning signal according to the step S300 issued in the form of another radio message to the parking management system. The parking management system then automatically creates a reminder or a penalty notice for the vehicle occupant for the incorrect occupancy of the parking lot PP.

For this purpose, according to a further sub-step S310 photographing the vehicle registration number of the vehicle FZ with the aid of the charging station-side camera KM and attaching the photo recording to the parking management system in a manner known to the person skilled in the art so that the vehicle clearly identifies FZ or its users and thus correctly delivers the reminder or the fine notification becomes.

In addition, for the sake of completeness, it should be mentioned that in the 1 Example shown, in which an inductive energy transmission is described, of course, in a similar mutated form also applies to a wired charging the vehicle, or a solution with a wired energy transfer (instead of an inductive energy transfer) is included in the scope.
