Description

The invention relates to a method for operating an operating interface for a motor vehicle and an operating interface for a motor vehicle. The invention further relates to a motor vehicle.

Modern motor vehicles have contactless operating interfaces at the rear with which the tailgate can be opened and/or closed. For example, an indicated kicking movement can be carried out under the rear to effect a tailgate opening.

From the US 2007/0205863 A1 a vehicle, in particular a motor vehicle, is known, comprising a flap that opens automatically based on an opening command, the opening command taking place without manual actuation of an unlocking/locking mechanism. There is a proximity sensor and a control device coupled to it, the control device being designed in such a way that it detects the presence of a valid access authorization means within an environmental area and, when a valid access authorization means is detected, activates the unlocking/locking mechanism depending on the presence of an unlocking signal from the proximity sensor Release of the automatically opening flap activated.

From the US 2016/0137165 A1 a method for detecting a functional operation on vehicles is known. Here, signals from a proximity sensor are monitored for a signal change in the form of a characteristic first signal response, which indicates an approach to the proximity sensor. The signals from the proximity sensor are then observed for a period of time, with the method being aborted if the signal response of the proximity sensor changes by more than a predetermined value within the period of time. After the period of time has elapsed, a signaling device is activated in order to signal to the operator that the actuation time has expired. The signals from the proximity sensor are now monitored for a second period of time, with the method only continuing if the signal from the proximity sensor changes by more than a predetermined value within the second period of time. In this case, the function is activated on the motor vehicle.

From the DE 10 2009 023 594 A1 a method and a device for automatically actuating a closing element of a vehicle are known. The locking element is actuated when a movement of an object corresponding to a predetermined movement profile is detected in an area surrounding the vehicle and when a vehicle key assigned to the vehicle is detected at the same time. On the one hand, it is possible that the movement of the object in the surrounding area of the vehicle is monitored through the interaction of a capacitive sensor and an optical sensor or that the movement profile first includes an approach to the vehicle and a subsequent removal from the vehicle, so that the closing element is only activated after it has been removed from the vehicle.

From the DE 10 2008 025 669 A1 a vehicle is known with a sensor for detecting the presence of a vehicle occupant and another sensor for detecting an occupant response in relation to an automatic opening of a vehicle closing element. An actuator opens the locking element when the presence and response of the occupant are detected. A signal from a transmitter outside the vehicle indicates the presence of an occupant. A photoelectric and/or optical device, an audio receiver and/or a touch-sensitive sensor detect the response. The optical device projects a beam of light, and breaking the beam with a gesture signals the response. An automatic closure element opening device includes an RF receiver adapted to receive an RF signal to detect an occupant presence, a sensor for detecting the occupant response, and an actuator for opening the closure element when both the presence and the The occupant's response can be detected. A method for automatically opening the closure element includes detecting an occupant presence and an occupant response and automatically opening the closure element when a predetermined response is detected.

From the DE 10 2016 212 804 A1 a method and a system for the contactless opening of a vehicle door, in particular a tailgate, in a vehicle and the use of the system in a vehicle are known. An electronic key is registered in a predetermined area using first radio signals and a gesture carried out by a user with the electronic key is detected using a gesture sensor. The gesture carried out by the user with the electronic key is also compared with at least one predetermined gesture and authorization of the electronic key is checked using second radio signals. The vehicle door, in particular the tailgate, of the vehicle is opened when the gesture performed by the user with the electronic key essentially matches at least one predetermined gesture and the electronic key is used to open it the vehicle door, especially the tailgate, of the vehicle is authorized.

The invention is based on the object of improving a method for operating an operating interface for a motor vehicle and operating interface for a motor vehicle, in particular with regard to ease of use.

The object is achieved according to the invention by a method with the features of patent claim 1 and a device with the features of patent claim 9. Advantageous embodiments of the invention result from the subclaims.

In particular, a method for operating an operating interface for a motor vehicle is provided, wherein a control device is used to determine via a wireless communication interface whether an ID transmitter intended to authorize an operation is within a predetermined authorization range and, in addition, the ID transmitter is on a gesture detection area of at least one gesture sensor approaches or additional activation takes place by means of the ID transmitter, and if this is detected or has been detected, the at least one gesture sensor is activated by means of the control device after a person has entered the gesture detection area of the at least one gesture sensor and one of the Gesture detected by at least one gesture sensor is recognized and at least one operating signal for at least one function of the motor vehicle is generated and output from the recognized gesture.

Furthermore, in particular, an operating interface for a motor vehicle is created, comprising at least one gesture sensor, a wireless communication interface, set up to communicate with an ID transmitter, and a control device, wherein the control device is set up to determine via the wireless communication interface whether a Operation of the intended ID transmitter is located within a predetermined authorization area and additionally approaches a gesture detection area of the at least one gesture sensor or is additionally activated by means of the ID transmitter, and if this is determined or has been determined, after a person has entered the gesture detection area of the at least one gesture sensor to activate the at least one gesture sensor and to recognize a gesture detected by the at least one gesture sensor and to generate and output at least one operating signal for at least one function of the motor vehicle from the recognized gesture.

The method and the device make it possible to simplify operation of functions of the motor vehicle from the outside. In particular, the method and the operating interface make it possible for a person other than the person who has the ID transmitter to carry out an operation on the operating interface. For this purpose, the first condition for activating at least one gesture sensor via a wireless communication interface, which can also be a communication interface of the motor vehicle, is to determine whether an ID transmitter intended to authorize an operation is within a predetermined authorization range. As a second condition, it is also determined whether the ID transmitter is approaching a gesture detection area of the at least one gesture sensor or whether activation takes place using the ID transmitter. An approach is determined here, for example, by a change in position of the ID transmitter, whereby the positions can be determined by means of the communication interface from the communication with the ID transmitter and/or in some other way. Activation using the ID transmitter includes generating an activation signal in the ID transmitter by executing a gesture intended for activation near the ID transmitter, which is detected by a sensor system of the ID transmitter and is converted into an activation signal (e.g. tapping on the ID transmitter, stomping your foot or pressing a button, etc.). Only when both conditions are met is the at least one gesture sensor activated when a person enters the gesture detection area of the at least one gesture sensor. After activating the at least one gesture sensor, gestures are detected by the at least one gesture sensor and a signal representing the detected gesture is transmitted to the control device. The control device recognizes a gesture based on the signal and generates at least one operating signal for at least one function of the motor vehicle linked to the recognized gesture and outputs the generated at least one operating signal.

An advantage of the disclosed method and the disclosed operating interface is that a second person who is not wearing the ID transmitter can trigger a function of the motor vehicle through a gesture in the detection range of the at least one gesture sensor, for example a tailgate of the motor vehicle can be opened without contact. For authorization, only a person with the specified ID provider needs to be within the authorization area, provided the two aforementioned conditions are met. Nevertheless, incorrect operation can be avoided: In particular, a static position of the ID transmitter within the authorization area activates If a person is present in the gesture detection area, it does not automatically activate at least one gesture sensor.

A typical example scenario in which the operating interface can be used to advantage is the following: A couple goes shopping and then moves towards the rear of the motor vehicle at a distance of a few meters. The next person carries the ID transmitter. The person in front reaches the gesture detection area of a gesture sensor first. Since authorization can be carried out by the subsequent ID transmitter without the ID transmitter itself having to be within the gesture detection area, the person in front can already trigger a function on the operating interface, for example opening the tailgate.

An ID transmitter is in particular an intelligent vehicle key (e.g. a SmartMobile radio key) or a smartphone that is used for authorization. Communication and/or position determination can take place, for example, using ultra-wideband technology (UWB), e.g. according to IEEE 802.15.4a, and/or via Bluetooth.

The authorization area includes in particular an area of a few meters, in particular a radius of a few meters, around the at least one gesture sensor. For example, the authorization area can have a radius of 6 meters.

The gesture detection area of the at least one gesture sensor in particular includes a smaller area than the authorization area and lies in particular within the authorization area. For example, the gesture detection area can include a semicircle in front of the at least one gesture sensor with a radius of 1 meter.

A gesture sensor can be a sensor that works capacitively, optically, inductively and/or based on another physical method. In particular, the gesture sensor delivers a signal that is representative of a distance and/or movement of a person within the gesture detection area.

The at least one function of the motor vehicle can include at least one of the following functions: tailgate opening, door opening, unlocking the motor vehicle, opening or closing a fuel tank flap, retracting or extending a trailer hitch, folding down or folding up seats or seat backs, lighting control for access to the motor vehicle, convertible top control Convertibles, opening or closing a sunroof.

Parts of the operating interface, in particular the control device, can be designed individually or collectively as a combination of hardware and software, for example as program code that is executed on a microcontroller or microprocessor. However, it can also be provided that parts are designed individually or combined as an application-specific integrated circuit (ASIC).

In one embodiment it is provided that the activation of the at least one gesture sensor is signaled by means of at least one signaling device. This allows one or more users to be directly signaled that the at least one gesture sensor is ready or activated for detection and that operation can take place. The at least one signaling device can, for example, comprise at least one optical signaling device, for example one or more light-emitting diodes (LEDs). These can be supplied with a current during or after activation so that they light up. The operating interface includes the at least one signaling device, which is correspondingly controlled by the control device.

In one embodiment it is provided that an approach of a person and/or the ID transmitter to the gesture detection area of the at least one gesture sensor is signaled by means of at least one further signaling device. This allows one or more users to be directly signaled that the person and/or the ID provider intended for authorization is approaching. The at least one further signaling device can, for example, comprise at least one optical signaling device, for example one or more light-emitting diodes (LEDs). For example, a number of LEDs arranged next to one another can be gradually supplied with a current depending on the progress of the approach, so that they are gradually made to light up. The operating interface includes the at least one further signaling device, which is controlled accordingly by the control device. The at least one further signaling device and the at least one signaling device can also be identical.

In one embodiment it is provided that the operating interface is at least partially formed in an emblem of a motor vehicle. As a result, an already marked area of the motor vehicle can be used to form the operating interface. In particular can the operating interface can be at least partially integrated into an emblem on a rear of the motor vehicle. For example, an emblem module can be provided in which the operating interface is integrated and which forms or includes the emblem.

In one embodiment it is provided that after activating the at least one gesture sensor, at least one display device is used to display which function or functions can be operated using the operating interface. This allows a user to be shown the functions that can be triggered. The operating interface includes the at least one display device, which is controlled accordingly by the control device. In a simple example, the display device includes, for example, backlit pictograms or icons, each of which corresponds to the functions that can be triggered. The backlighting is activated when at least one gesture sensor has been activated.

In one embodiment it is provided that when or after activating the at least one gesture sensor, a change in position and/or change in orientation of at least part of the operating interface takes place. This allows a position and/or an orientation of the gesture sensor to be adapted to a person who is in the gesture detection area. For example, a position and/or an orientation of the at least one gesture sensor can be changed such that the at least one signaling device can be detected particularly well. If the operating interface is at least partially formed in an emblem of the motor vehicle, it can be provided, for example, that the emblem is tilted, as is already known for extending or activating a rear-view camera. As a result, an outside of the emblem points upwards after tilting, so that the outside can be better perceived. If there is a signaling device or a display device on this outside, for example for displaying the operable functions, this can be better detected by the person standing in front of the operating interface or the at least one gesture sensor within the gesture detection area. For this purpose, the operating interface can have an actuator system that is controlled accordingly by the control device.

In one embodiment it is provided that at least some of the gestures are designed as finger gestures and/or swipe gestures. This enables simple and contactless operation on the operating interface. In principle, however, other gestures can also be provided, which include, for example, the use of other and/or additional body parts of a person (e.g. hip swing, rotation of the entire body, etc.).

In one embodiment it is provided that a function of the motor vehicle to be controlled is or is determined via a direction of the finger gesture and/or the swipe gesture. This allows several functions of the motor vehicle to be operated in a way that is easy to learn and easy to carry out. In particular, it can be provided that a display device, for example one or more LEDs or a backlit display, displays the functions and the directions of the finger gestures and/or swiping gestures associated with triggering the functions.

Further features for the design of the operating interface result from the description of embodiments of the method. The advantages of the operating interface are the same as in the embodiments of the method.

Furthermore, a motor vehicle is also created, comprising at least one operating interface according to one or more of the described embodiments.

• 1 eine schematische Darstellung einer Ausführungsform der Bedienschnittstelle für ein Kraftfahrzeug;
• 2 eine schematische Darstellung einer Ausführungsform der Bedienschnittstelle in einem Emblem am Heck eines Kraftfahrzeugs.

The invention is explained in more detail below using preferred exemplary embodiments with reference to the figures. Show here:

• 1 a schematic representation of an embodiment of the operating interface for a motor vehicle;
• 2 a schematic representation of an embodiment of the operating interface in an emblem at the rear of a motor vehicle.

In 1 a schematic representation of an embodiment of the operating interface 1 for a motor vehicle 50 is shown. The operating interface 1 includes a gesture sensor 2, a wireless communication interface 3 and a control device 4. The gesture sensor 2 can detect gestures of a person within a gesture detection area 10. In principle, the gesture sensor 2 can be designed in any way, for example, it can work according to a capacitive, optical, inductive and/or other method, for example using UWB. The gesture detection area 10 is, for example, semicircular with a radius of 1 meter. The wireless communication interface 3 is set up to communicate with an ID transmitter 30, for example via Bluetooth and/or UWB. The wireless communication interface 3 can also be a communication interface of the motor vehicle 50.

The control device 4 is set up to determine via the wireless communication interface 3 whether an ID transmitter 30 intended to authorize an operation is within a predetermined authorization area 11. The authorization area 11 includes, for example, a circular area around the operating interface 1 with a radius of 6 to 9 meters.

Furthermore, the control device 4 is set up to determine whether the ID transmitter 30 is also approaching the gesture detection area 10 of the gesture sensor 2 or whether activation is additionally carried out by means of the ID transmitter 30.

• - ein zur Autorisierung einer Bedienung vorgesehener ID-Geber 30 befindet sich innerhalb eines vorgegebenen Autorisierungsbereiches 11 UND der ID-Geber 30 nähert sich an den Gestenerfassungsbereich 10 des Gestensensors 2 an (verdeutlicht durch den Richtungspfeil 12) ODER
• - ein zur Autorisierung einer Bedienung vorgesehener ID-Geber 30 befindet sich innerhalb eines vorgegebenen Autorisierungsbereiches 11 UND zusätzlich erfolgt eine Aktivierung mittels des ID-Gebers 30.

There are therefore at least two constellations that are determined by the control device 4:

• - an ID transmitter 30 intended for authorizing an operation is located within a predetermined authorization area 11 AND the ID transmitter 30 approaches the gesture detection area 10 of the gesture sensor 2 (illustrated by the directional arrow 12) OR
• - an ID transmitter 30 intended for authorizing an operation is located within a predetermined authorization area 11 AND, in addition, activation takes place using the ID transmitter 30.

If one of the two possibilities is or has been determined, the control device 4 checks whether a person is entering or has entered the gesture detection area 10 of the gesture sensor 2. A position of the person entering does not have to coincide with a position of the ID transmitter 30. If a person enters the detection area 10, the control device 4 activates the gesture sensor 3. After activation, detected gestures can be recognized and trigger a function of the motor vehicle 50.

The control device 4 recognizes gestures detected by the gesture sensor 2 and generates from a recognized gesture at least one operating signal 20 for at least one function 21 of the motor vehicle 50 linked to the recognized gesture and outputs the generated at least one operating signal 20. The operating signal 20 can be analog or digital, for example as a data packet that is supplied via a CAN bus (not shown) to a device of the motor vehicle 50, for example an actuator of the motor vehicle 50 for opening or closing the tailgate or for unlocking or opening a Vehicle door of motor vehicle 50.

Further functions can be: tailgate opening, door opening, unlocking the motor vehicle 50, opening or closing a fuel filler flap, retracting or extending a trailer hitch, folding down or folding up seats or seat backs, lighting control for access to the motor vehicle 50, convertible top control of a convertible, opening or closing a sunroof .

The disclosed operating interface 1 is particularly advantageous if a position of the ID transmitter 30 does not coincide with a position of a person using the operating interface 1 through gestures. A typical example scenario is the following: A couple goes shopping and then moves towards the rear of the motor vehicle 50 at a distance of a few meters. The following person carries the ID transmitter 30. The preceding person reaches the gesture detection area 10 of the gesture sensor 2 first. Since authorization can be carried out by the subsequent ID transmitter 30 without the ID transmitter 30 itself having to be within the gesture detection area 10, the preceding person can already trigger a function on the operating interface 1.

It can be provided that the operating interface 1 has at least one signaling device 5, it being provided that the activation of the gesture sensor 3 is signaled by means of the at least one signaling device 5. The control device 4 controls the at least one signaling device 5 for this purpose. The at least signaling device 5 can include, for example, optical signaling, for example in the form of lighting using LEDs.

It can also be provided that an approach of a person and/or the ID transmitter 30 to the gesture detection area 10 is signaled by means of at least one further signaling device 6. The at least one further signaling device 6 can also be the at least one signaling device 5, which is used for signaling the activation of the gesture sensor 4. The approach can be signaled, for example, in the form of a progress display using LEDs arranged next to one another. The LEDs can also be arranged in an interior, for example on an interior door panel that is visible from the outside.

It can be provided that the operating interface 1 is at least partially formed in an emblem 51 of a motor vehicle 50. At least part of the operating interface 1 is then designed in particular as a module, the outside of which forms the emblem. In particular, it can be provided that a rear-view camera is also integrated into such a module.

It can be provided that after activating the gesture sensor 2, a display device 7 is used to display which function or functions can be operated using the operating interface 1. For example, pictograms or icons representing the individual functions can be depicted on an outside of the operating interface 1, for example in an area in which the emblem 51 of the motor vehicle 50 is formed. After activation, the pictograms or icons will be backlit so that they become visible. The control device 4 controls the display device 7, for example one or more LEDs for backlighting the pictograms or icons, accordingly.

It can be provided that a change in position and/or orientation of at least part of the operating interface 1 takes place during or after activation of the gesture sensor 2. For this purpose, the operating interface 1 in particular has an actuator system (not shown), which is controlled accordingly by the control device 4 during or after activation. By driving, the actuator tilts, for example, an emblem in which the operating interface 1 is at least partially integrated, so that an outside of the emblem at least partially points upwards, for example at an angle of 45°.

It can be provided that at least some of the gestures are designed as finger gestures and/or swiping gestures. This allows for a simple and easy-to-learn non-contact operation of the operating interface 1.

In a further development, it can be provided that a function of the motor vehicle 50 to be controlled is or is determined via a direction of the finger gesture and/or the swipe gesture. For example, the following gestures can be provided to trigger three different functions of the motor vehicle 50: wiping from right to left, wiping from left to right and wiping from bottom to top, whereby the wiping must, for example, take place along the emblem, in particular without the emblem to touch. When these gestures are recognized, the control device 4 generates and outputs a corresponding operating signal 20 so that the corresponding function is started.

In 2 a schematic representation of an embodiment of the operating interface 1 is shown. The operating interface 1 is at least partially formed in an emblem 51 at the rear of a motor vehicle 50. The operating interface 1 is basically like the one in the 1 Embodiment shown is formed, wherein the gesture sensor, the communication interface and the control device are not visible since they are arranged behind an outside 8 of the operating interface 1.

It is envisaged that the operating interface 1 has a signaling device 5, with provision being made for the activation of the gesture sensor to be signaled by means of the signaling device 5. The control device controls the signaling device 5 for this purpose. The signaling device 5 is ring-shaped and arranged in an outer area of the emblem 51 and comprises a large number of LEDs arranged next to one another. If the gesture sensor is activated, the LEDs light up.

It is further provided that a change in position and/or orientation of at least part of the operating interface 1 takes place during or after activation of the gesture sensor. For this purpose, at least part of the emblem 51 is tilted along a horizontal axis, so that the outside 8 then points at least partially upwards. For this purpose, the control device 4 ( 1 ) an actuator (not shown) that causes the tilting (and tilting back after the process has been completed). An actuator system can also be used here, which is used to tilt the emblem when extending or activating a rear-view camera arranged behind the emblem 51.

Furthermore, it is provided that after activating the gesture sensor, a display device 7 is used to display which function 15 or which functions 15 can be operated using the operating interface 1 after activation. The display device 7 includes, for example, backlit pictograms 16 or icons, each of which corresponds to one of the triggerable functions 15. The functions 15 in the embodiment shown are, for example, the following: unlocking (left), opening the tailgate (top) and folding the seat back (right).

The individual functions 15 can be triggered or activated by swiping gestures 17. To do this, a hand must be moved or “wiped” over the emblem 51, in particular without touching the emblem 51. It is provided here that a function 15 to be triggered is or is determined via a direction of the swipe gesture 17.

In particular, it is provided that the signaling of the active gesture sensor by means of the signaling device 5 and the display of the operable functions 15 only take place after the emblem 51 has been tilted. This can prevent any disturbing light from being emitted directly to the rear.

The disclosed operating interface 1 and the disclosed method for operating the operating interface 1 increase comfort when operating functions 15 of the motor vehicle 50 outside the motor vehicle 50.
