Description

The invention relates to a parking authorisation device, in particular a parking authorisation device for a vehicle with an electric drive.US 2011 / 0068739 A1 shows a parking management system with a plurality of parking spaces for electric vehicles. When a vehicle is parked in a parking lot, it requests a time slot for parking. If the time slot is clear, the park management system accepts the request and transmits an authorization code. An alarm signal is triggered as long as no authorization code has yet been entered.CH 688 599 A5 shows a charging station for electric vehicles which has two spring-loaded buffer-shaped contactors which are arranged in a stationary manner and which interact with contact elements of wide area on the bumper of an electric vehicle. Without an electric vehicle on the buffers, the charging point is deactivated by an OFF limit switch, and is activated by an ON switch when the electric vehicle is positioned. If the electric vehicle emits a coded signal via a transmitting device and is authorized to use the charging station, a green lamp of a signaling system flashes as soon as the electric vehicle has released the OFF limit switch by approximating the buffer. As soon as the ON switch recognizes the end position of the electric vehicle, the green lamp is continuously switched on. Without authorisation, a red lamp of the signalling system lights up.WO 2012 / 013427 A2 discloses a device and a method for tamper-proof charging of an electric vehicle via a charging column.It is therefore an object of the invention to provide a novel parking permission device.The object is achieved by the subject matter of claim 1.The visual display via a display device as a function of a first signal from an external data station enables an advantageous display and can be visually checked by a parking controller, for example.According to a preferred embodiment, the display device comprises at least one of the following displays:interior lighting,ambient external lighting,a stationary light,low beam, low beam,- rear light,flashing light.Of course, in addition or alternatively, another lighting device installed in the vehicle can also be provided. Thus, already existing displays of a vehicle can be used, or additional displays can be provided.According to a preferred embodiment, the control device is configured to enable the output of a flashing light via the display device. A flashing light is particularly easy to recognize as a signal for the human brain.According to a preferred embodiment, the control device is designed to enable the output of a continuous light via the display device. Continuous light can be used, for example, to indicate a charging process, and continuous light is well suited, in particular in the case of large, high-intensity displays.A traction battery is assigned to the parking authorization device, and the control device is designed to enable the visual display to be output during a charging process of the traction battery. This enables an advantageous use of the parking authorisation device in connection with a charging process.According to a preferred embodiment, a traction battery is assigned to the parking authorization device, and the control device is designed to enable the output of the visual display after or during a charging process of the traction battery. This allows, for example, an indication that the charging process has ended.The control device is designed to receive a first signal from an external data station designed as a charging station via the data transmission device, and the first signal comprises an authorization signal of the external data station, wherein the control device is designed to output the visual display via the display device as a function of the authorization signal. This allows the external terminal to directly influence the visual display.The control device is designed to output a second signal to the external data station via the data transmission device, which second signal comprises an identification signal in order to enable the external data station to check the authorisation. This allows the external terminal to check the authorisation without providing special devices for identification.According to a preferred embodiment, the control device has a data memory with position data and is designed to receive the first signal from an external data station designed as a satellite navigation system via the data transmission device, and the control device is designed to determine a position value for the position of the parking authorisation device from the first signal, wherein the control device is designed to determine the authorisation depending on the position value and the position data from the data memory and to output the visual display via the display device. This enables a very advantageous checking of the authorisation by the participation of the parking authorisation device. Alternatively, location information from a database may be used in the backend.According to a preferred embodiment, the control device is configured to receive a radio signal via the data transmission device and to determine a position value for the position of the parking authorisation device from this, wherein the control device is configured to output a second signal to the external data station via the data transmission device, which second signal comprises the position value in order to enable the external data station to check the authorisation. This results in an advantageous interaction of the parking authorisation device and the external data station, and the external data station does not have to have any sensors for detecting the position of the parking authorisation device.According to a preferred embodiment, the parking authorisation device is arranged in a vehicle, wherein the display device is at least partially visible from outside the vehicle. The visibility of the display device from outside the vehicle allows easy inspection.According to a preferred embodiment, the control device is designed to receive a first signal from the external data station via the data transmission device, which first signal contains information which directly determines which optical display is to be output by the display device, in order thereby to enable specification of the optical display by the external data station. This makes manipulation of the visual display difficult and the external terminal can use uniform visual displays.Further details and advantageous developments of the invention are evident from the exemplary embodiments described below and illustrated in the drawings, which are in no way to be understood as limiting the invention, and from the dependent claims.

FIG. 1 shows a vehicle 10 having a traction battery 14 and an electric drive 12.A parking authorisation device 20 is provided on or in the vehicle 10, and the parking authorisation device 20 has a control device 30, a display device 32, a data memory 36 and a data transmission device 34 for data transmission between the parking authorisation device 20 and an external data station 80. The control device 30 is designed to receive a first signal 51 from the external data station 80 via the data transmission device 34 and to output a visual display 33 via the display device 32 as a function of the first signal 51.The data transmission device 34 is preferably designed to output a second signal 52 to the external data station 80.The external terminal 80 preferably also has a display device 82 for outputting an optical display 83.The display device 32 preferably comprises at least one of the following display devices:interior lightingAmbient outdoor lighting- stationary lightlow beam - low beam- Backlightflashing light- LED.The LED may be provided, for example, on the upper side of the dashboard, so that it is visible through the front windshield. Preferably, a safe LED is used. The remaining display devices are usually at least partially present on vehicles and can be used as display device 32. Any legal requirements that may be present must be complied with here.The display device 32 is preferably designed as a tamper-proof display device 32, i.e. it is protected against manipulations such as bridging.The display device 82 at the external data station 80 can be, for example, a display or another lighting means.The control device 30 is preferably configured to enable a flashing light to be output via the display device 32. Such a flashing light can be used, for example, to indicate that the authorisation has not yet taken place. A flashing light of another color may also be output if the authority has been denied.The control device 30 is preferably designed to enable the output of a continuous light via the display device 32, i.e. a light which is switched on for a longer time, for example during the entire charging process, or during the period of a valid parking authorization, or for 10 minutes.Control device 30 is preferably designed to enable the output of visual display 33 during a charging process of traction battery 14. As a result, during the charging process, it is possible to check, for example by a parking monitor, whether there is authorisation for the parking space or for the charging.The control device 30 is preferably designed to enable the output of the optical display 33 after the termination of a charging process of the traction battery 14. For this purpose, for example, a different optical display 33 can be selected than during the charging process in order to indicate that the authorisation is running.The external data station 80 is preferably a charging station for a vehicle having a traction battery 14. the charging station can thus determine directly, by outputting a first signal 51, which visual display 33 is displayed on the vehicle 10 or whether an indication is actually occurring.When using a charging station as external data station 80, control device 30 is preferably designed to output second signal 52 to the charging station via data transmission device 34, which second signal 52 includes an identification signal, in order to enable external data station 80 to check the authorization. The control device 30 can thus transmit an identification signal, which allows the charging station to ascertain the identity of the vehicle 10. The charging station can then determine, for example via a database, whether the vehicle 10 or the parking authorisation device 20 are authorised to park in the parking space or to carry out a charging process. If this is the case, the charging station can output a first signal 51 to the parking authorisation device 20 in order to activate the visual display 33.In another exemplary embodiment, the control device 30 can be designed to receive the first signal 51 from an external data station 80 designed as a satellite navigation system via the data transmission device 34. For this purpose, the control device 30 is preferably designed to determine a position value for the position of the parking authorisation device 20 from the first signal 51. Depending on the position value and the position data from the data memory 36, the parking authorisation device 20 can determine whether authorisation for the current position is present and output a corresponding visual display 33 via the display device 32.As satellite navigation systems, it is possible, for example, to use a satellite navigation system. Data of the following systems can be used:GPS (Global Positioning System),Galileo,- ERA-GLONASS.Satellite navigation systems usually do not allow a second signal 52 from the data transmission unit 34 to the satellite navigation system.The control device 30 is preferably designed to receive a first signal 51 from the external data station 80 via the data transmission device 34, which first signal 51 contains information which directly determines which optical display 33 is to be output by the display device 32, in order thereby to enable specification of the optical display by the external data station 80. This allows the external terminal 80 to determine which optical signal is to be displayed for which operating state. A uniform display in a parking lot or at a charging station can thus be used.FIG. 2 shows a further exemplary embodiment for the use of the parking authorisation device 20. the vehicle 10 is only schematically illustrated and corresponds in design preferably to the exemplary embodiment of FIG. 1. the parking authorisation device 20 can receive radio signals 101 from a satellite 100 via the data transmission device 34.The external data station 80 has a charging park 90 with at least one charging column 91, and a backend 92 is provided which provides the basic infrastructure. The backend 92 is preferably connected to the charging park 90 via a line 94 or wirelessly in order to enable a data transmission. The data transmission device 34 of the parking authorisation device 20 is connected to the charging column 91, to the backend 92 or to the charging column 91 and the backend 92 in a wired or wireless manner.The first data 51 and the second data 52 between the data transmission device 34 and the charging column 91 are preferably transmitted via the charging cable, but they can also be transmitted wirelessly. A data transmission between the data transmission device 34 and the backend 92 is preferably effected wirelessly, and in the case of a wireless data transmission, the backend 92 can either not determine the position of the vehicle 10 or of the parking authorisation device 20 at all, or additional position detection sensors are required, for example. Cameras in the respective parking space. The control device 30 (cf. FIG. 1 ) is preferably designed to receive a radio signal 101 via the data transmission device 34 and to determine a position value for the position of the parking authorisation device 20 from this. For this purpose, for example, the signal 101 of a satellite navigation system 100 can be used, as described above. However, it is also possible, for example, to carry out a position determination via WLAN routers present in the vicinity. If the control device 30 has determined a corresponding position value, it preferably outputs a second signal 52 to the backend 92 via the data transmission device 34, which second signal 52 comprises the position value. The data station 80 or the backend 92 can hereby perform a checking of the authorisation with the aid of the position value.Data can be exchanged via the data line 94, so that the charging column 91 is activated.Of course, within the scope of the present invention, numerous modifications and variations are possible.List of reference characters10 Vehicle 12 Drive 14 Traction battery 15 Charging line 20 Parking authorisation device 30 Control device 32 Display device 33 Display 34 Data transmission device 36 Data memory 51 First signal 52 Second signal 80 External data station 82 Display device 83 Display 90 Charging park 91 Charging column 92 Backend 94 Signals between charging park and backend
