Description

TECHNICAL FIELD

[0001] The utility model relates to a method for interrupting a charging process of an electrically operated vehicle and a system for interrupting a charging process of an electrically operated vehicle. Furthermore, the utility model relates to an electrically operated vehicle which is configured to carry out the method and / or comprises the system. BACKGROUND

[0002] In order to charge an electric vehicle, a charging plug of a charging station is usually connected and locked with a charging connector unit of the vehicle in order to prevent a separation of the charging plug from the charging connector unit during the charging process. The charging connector unit is for example part of a charging flap system which comprises a charging socket as an electrical connection element and a closing flap or charging flap which covers the charging connector unit when the electric vehicle is not being charged.

[0003] A button is usually used for the charging unlocking, which is arranged within or at the charging socket. Such a charging unlocking button has the disadvantage that it leads to higher production costs. Furthermore, the charging unlocking button leads to an additional operating step, because the button has to be pressed in order to charge.

[0004] Furthermore, the button can influence the design of the vehicle, so that in many cases the button is difficult to find for the user due to the design, especially when the user is a changing user, for example in the case of carpooling or rental cars. Especially in the dark, the user has the problem that the button cannot be seen, because the button is designed to be as visually inconspicuous as possible due to the design in most cases.

[0005] In order to avoid the button for the reasons mentioned, there are solutions which interrupt the charging process as soon as the user actively unlocks the vehicle or the vehicle is unlocked by an identification ID transmitter. The disadvantage of such a solution is for example that, if a person for example only wants to sit in the vehicle, or wants to take something out of the locked vehicle or wants to store an item in the vehicle during the charging, the charging process is interrupted by unlocking the vehicle and the vehicle is not continued to be charged. Furthermore, in many cases the charging process cannot be resumed automatically after the charging interruption, because the user has to log in again to the charging station for example in order to continue the charging process.

[0006] An alternative solution is that the charging process is not interrupted when the vehicle is unlocked. Here, the user has to enter the vehicle first, carry out the unlocking in an operating menu of a display and operating unit of the vehicle and then be able to pull out the charging plug. This solution is relatively complex for the user and furthermore the function in the display and operating unit of the vehicle can not be found or not easily found, especially when the user is a changing user who is not familiar with the vehicle. SUMMARY

[0007] The task is to avoid the above-mentioned disadvantages and to provide a charging unlocking, which does not require a charging unlocking button, avoids additional operating steps and enables entry into the vehicle during charging without the charging process being ended and the charging connector being unlocked as a result.

[0011] Preferably, the signals of one or more microphones and / or further sensors are additionally taken into account in the analysis.

[0012] Preferably, one or more status recognition signals reflecting the status of one or more vehicle components are additionally taken into account in the analysis.

[0013] Preferably, the charging process is only interrupted when it is determined in the analysis that the person, after approaching the charging connector unit purposefully, remains in the vicinity of the charging connector unit for a time that exceeds a defined minimum time period.

[0014] According to one aspect of the utility model, a kind of system for interrupting the charging process of electrically operated vehicle, comprising: control device for controlling charging process, the control device is connected by signal connection with parking sensor and / or camera installed in vehicle and is connected with sensor for receiving identification transmitter signal, to receive its signal;Coupled to control device, the computing unit of the computing unit is configured to analyze received signal in terms of movement pattern;Wherein, the computing unit includes decision logic, when indicating that a person authorized to use the vehicle is approaching the charging connector unit of the vehicle purposefully movement pattern is recognized based on analysis, this decision logic promotes control device and interrupts charging process.

[0015] Preferably, the computing unit is configured to execute artificial intelligence, which recognizes an intention of the user to end the charging process from the received signals and / or image data.

[0016] Preferably, the control device is additionally connected with one or more microphones and / or further sensors via a signal connection.

[0017] Preferably, the control device is connected with at least one state recognition unit via one or more further signal connections in order to receive state recognition signals reflecting a state of one or more vehicle components and to take the state recognition signals into account in the analysis.

[0018] According to a further aspect of the utility model, an electrically operated vehicle is provided, which is configured to carry out a method according to the utility model and / or comprises a device according to the utility model.

[0019] The advantages, features and details described in connection with the method also apply to the other aspects of the utility model, respectively, to each other.

[0020] The utility model uses, inter alia, the following basic idea, i.e. the function recognition of the operation desired by the customer is recognized as a planned charging process. If necessary, the recognition can be supported via KI (artificial intelligence).

[0021] A particular advantage of the utility model is the use of functions and hardware that are usually already present in a vehicle, such as, inter alia, parking sensors, cameras, etc. By suitable combination of KI functions and, in particular, by supplementation of KI functions, costs can be significantly reduced compared to a button solution, wherein, at the same time, the interests of the vehicle user are increased.

[0026] In the drawings, elements that are identical or correspond to each other are denoted by the same reference signs, respectively, and are therefore not newly described (unless appropriate).

[0027] Figure 1 A vehicle 10 is shown, which is equipped with a system 11 for interrupting a charging process according to a particularly preferred embodiment of the utility model.

[0028] The system or charging interruption system 11 comprises a control device 12 for controlling a charging process, which is carried out for example at an external charging station, not shown in the drawing. The system 11 is connected via a signal connection with a parking sensor 13 and / or a camera 14 installed in the vehicle 10, and with a sensor or ID sensor 15 for receiving an identification transmitter signal, in order to receive the signals of the parking sensor, camera, sensor or ID sensor.

[0029] The signal connection, which is not visible in the drawing, is configured for example as a cable or bus system and / or also wirelessly.

[0030] The parking sensor 13 is configured for example as an ultrasonic sensor. These cameras 14 or a part thereof can also form a parking sensor.

[0031] In particular, the parking sensor 13 and / or the camera 14, which are provided as a parking aid in the vehicle, are used as part of the charging interruption system 11. This means that the signals of the parking sensor 13 and / or the parking camera 14 are used to identify, by means of an analysis of the signals, whether the charging should be interrupted.

[0032] Furthermore, an identification transmitter or ID transmitter 23, which has a key function for unlocking the vehicle 10 by means of a wireless transmission of an ID transmitter signal, and an identification sensor or ID sensor 15, which is used to receive an identification signal or ID signal, are also used as part of the charging interruption system 11. That is, the ID transmitter signal received in the sensor or ID sensor 15 is also used to identify, by means of an analysis of the signal, whether the charging should be interrupted, without the need for a button or other operating element to be actuated. In particular, a varying signal strength of the received ID transmitter signal is used to take the movement of the ID transmitter 23 and thus of the person 18 carrying the ID transmitter 23 into account in the analysis.

[0033] As a result, there is no need for a button or other operating element to be actuated. In particular, it is advantageous, but not necessarily required, for the vehicle 10 to be equipped with further sensors for the charging interruption identification.

[0034] The control device 12 can be additionally connected for example via a further signal connection with one or more microphones and / or further sensors. In particular, in the particular embodiment shown, a further sensor 16, which is configured for example as a camera and / or as a sound sensor, is arranged on or in the vicinity of a charging cover or charging connector unit 19 of the vehicle 10.

[0035] It is particularly advantageous for the control device 12 to be connected to at least one state recognition unit 20 via one or more further signal connections, which are not visible in the drawing. The state recognition unit 20 is configured in such a way that it receives state recognition signals which reflect the state of one or more vehicle components. Here, the state recognition signals of the vehicle components recognized by the state recognition unit 20 are taken into account in the analysis by means of the computing unit 17. For example, the state recognition unit 20 recognizes whether the doors 22, 32 of the vehicle 10 are open, which doors of the vehicle are open, if necessary, or in which state the doors are.

[0036] The computing unit 17, which is electrically coupled to the control device 12, is configured to analyze the signals received by the different sensors and / or cameras 13, 14, 15, 16 in terms of movement patterns. The computing unit 17 comprises a decision logic 21 (cf. Figure 3 ) which prompts the control device 12 to interrupt the charging process when, on the basis of the analysis of the received signals, a movement pattern 25 is recognized which indicates that the person 18 authorized to use the vehicle is approaching the charging connection unit 19 of the vehicle 10 purposefully. In Figure 1 In the example shown, the person 18 is approaching the charging connection unit 19 purposefully via a path X1.

[0037] The computing unit 17 combines the various received signals. If, in addition to the parking sensors 13 already installed in the vehicle and / or the vehicle cameras 14 installed in the vehicle for parking, further sensors and signal generators, for example sensors 14, 16 or others, are provided, they are advantageously used by appropriate mutual combination.

[0038] Thus, a better recognition of the intention of the user 18 to cause an interruption of the charging and to unplug the charging plug from the vehicle is provided. As a result of the charging interruption system 11, it is not necessary to operate a button or other operating unit.

[0039] The computing unit 17 is configured to execute artificial intelligence (KI) in the preferred example. To this end, the computing unit comprises a KI function unit 24 which determines the intention of the user to end the charging process from the received signals and / or image data and, if necessary, from the state recognition signals and their analysis. Here, the KI is stored as software in a data memory or implemented in the computing unit 17. The KI is configured in particular in such a way that it independently combines as many different signals or data as possible with one another.

[0040] Preferably, the computing unit 17 improves its analysis and thus its recognition independently and continuously by means of the implemented KI function 24 and thus imitates the behavior of the user 18 of the vehicle 10 in order to recognize the intention of the user. The intention of the user to cause an interruption of the charging is recognized only from the detected and stored movement patterns and, if necessary, from the vehicle state, without a manipulation button or other type of operating unit being required for this purpose.

[0041] Figure 2 It is also shown that the vehicle 10, however, is in a case in which no movement pattern leading to an interruption of the charging is recognized by means of the analysis by the computing unit 17.

[0042] In this example, the movement of the user 18 takes place along a path X2 which does not explicitly target the charging cover 19, but rather a door 22 of the vehicle 10, in this example the driver's door.

[0043] For all further details, reference is made to the above description of Figure 1 .

[0044] Figure 3 In connection with Figure 1 and Figure 2 a case recognition is shown which is in accordance with a particularly preferred embodiment of the method according to the application.

[0045] Here, Figure 1 a case is shown in which the driver or vehicle user 18 does not want to continue charging his vehicle 10. It is recognized by means of the movement pattern 25 of the driver 18, who for example has a key or ID transmitter 23 in his pocket, that the driver does not want to continue charging his vehicle 10. Then, the charging process is interrupted and the charging cable is unlocked. Thus, the driver 18 can disconnect the charging cable from the vehicle 10 or from the charging connection unit 19.

[0046] In contrast, Figure 2 a case is shown in which the driver or vehicle user 18 wants to continue charging his vehicle 10, i.e. the charging process should not be interrupted. It is recognized by means of the movement pattern 26 of the driver 18, who for example has a key or ID transmitter 23 in his pocket, that the driver only wants to unlock the door 22. In the case of this recognition, the charging cable remains locked in the charging connection unit 19.

[0047] In particular, as Figure 3 is shown, the method is executed as follows:

[0048] First, the KI function 24 implemented in the vehicle 10 recognizes, for example, that the vehicle 10 is being charged (block 31)

[0049] The environment of the vehicle 10 is monitored by means of a parking sensor 13 and / or a camera 14 installed in the vehicle. By means of the signals obtained, an environmental analysis with regard to movement patterns takes place. In particular, movement patterns are determined from the signals, which preferably indicate a targeted approach to the charging connector unit 19 in at least two dimensions due to the spatial course of the path x1 (including the continuous movement direction contained therein). This is carried out in particular by means of a computing unit 17 or a KI function, which is configured in such a way that it automatically learns from the paths detected to date and thus continuously improves the recognition security of the user's intention to end the charging process.

[0050] The control unit or control device 12 evaluates the feedback of the sensors 13, 15, 16 or the camera 14 and then decides whether the charging should be interrupted or the charging connector unit 11 unlocked (block 32).

[0051] By determining the ID transmitter signal transmitted by the ID transmitter 23 by means of the ID sensor 15, it is recognized that the ID transmitter 23 and thus the authorized vehicle user carrying the ID transmitter is located in the vicinity of the vehicle 10. This takes place in particular by means of the KI function (block 32).

[0052] By receiving the ID transmitter signal by means of the ID sensor 15, it is recognized that the ID transmitter 23 is located in the vicinity of the vehicle 10 (block 33)

[0053] For example, depending on the evaluation or environmental analysis by means of the parking sensor and / or the camera 14 and the received ID transmitter signal, for example, a movement pattern 25 is recognized, which proves that the authorized vehicle user 18 is approaching the charging cover 19 in a targeted manner (see Fig. 2). Figure 1 This is supported in particular additionally via the KI function 24 or the state recognition matrix in order to correctly recognize the state. In this case, the charging process is ended or interrupted by the control device 12 (block 34).

[0054] Preferably, it is also recognized in the analysis whether the authorized person stays in the vicinity of the charging cover 19 in a defined minimum time period after approaching the charging cover 19 in a targeted manner, which is for example 1 to 5 seconds, in particular approximately 2 to 3 seconds. The recognition security of the user's intention leading to the interruption of the charging is thus additionally also improved.

[0055] Alternatively or additionally, it can be recognized by means of a further sensor or microphone whether the charging cover 19 has been opened. This is also used to additionally improve the recognition security.

[0056] In particular, the state recognition signals of the vehicle 10 are taken into account in the analysis and evaluation.

[0057] For example, it is identified by including a status recognition signal that the vehicle door or the trunk lid is not open. This also strengthens the recognition of the user's intention to interrupt the charging process.

[0058] For example, as shown in Figure 2 the motion pattern 26 is identified by an evaluation or environmental analysis which certifies that the authorized person is not approaching the charging flap 19 and / or is approaching the vehicle door 22 purposefully instead.

[0059] For example, it is identified that the authorized person is staying in the vicinity of the driver's door 22.

[0060] For example, it is determined by the status recognition that the vehicle door or the trunk lid is open. This increases the likelihood that the user needs to access the interior space of the vehicle in order to, for example, deposit items therein or remove items and therefore does not necessarily intend to interrupt the charging process.

[0061] In particular, in interaction with the above-mentioned steps, the charging process is interrupted via the KI or KI function 24 and the charging connection 19 of the vehicle, for example configured as a charging socket, is unlocked.
